Scientists seeking to bring the fusion reaction that powers the sun and stars to Earth must keep the superhot plasma free from disruptions. Now researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered a process that can help to control the disruptions thought to be most dangerous.
Carrying extra body fat, especially around the middle, may be linked to brain shrinkage, according to new research. For the study, researchers determined obesity by measuring body mass index (BMI) and waist-to-hip ratio in study participants and found those with higher ratios of both measures had the lowest brain volume.
Well, that was the shortest, most easily resolved national emergency in U.S. history. Twelve hours ago, the president was preparing to set aside the regular process of law. By 9 p.m. eastern time? Not so much. Perhaps somebody pointed out that 15-year civil-engineering projects do not look very convincingly like emergency measures. “My house is burning! Time to begin the process of calling for de
Amyloid-β precursor protein (APP) is central to the pathogenesis of Alzheimer’s disease, yet its physiological function remains unresolved. Accumulating evidence suggests that APP has a synaptic function mediated by an unidentified receptor for secreted APP (sAPP). Here we show that the sAPP extension domain directly bound the sushi 1 domain specific to the -aminobutyric acid type B receptor subu

A team of European scientists has deliberately triggered electrical activity in thunderclouds for the first time, according to a new paper in the latest issue of Optics Express, the Optical Society's (OSA) open-access journal. They did this by aiming high-power pulses of laser light into a thunderstorm.
Termites perform key ecological functions in tropical ecosystems, are strongly affected by variation in rainfall, and respond negatively to habitat disturbance. However, it is not known how the projected increase in frequency and severity of droughts in tropical rainforests will alter termite communities and the maintenance of ecosystem processes. Using a large-scale termite suppression experimen
What Anita Radini noticed under the microscope was the blue—a brilliant blue that seemed so unnatural, so out of place in the 1,000-year-old dental tartar she was gently dissolving in weak acid. It was ultramarine, she would later learn, a pigment that a millennium ago could only have come from lapis lazuli originating in a single region of Afghanistan. This blue was once worth its weight in gold
The gene editing technique known as CRISPR is a revolutionary approach to treating inherited diseases. However, the tool has yet to be used to effectively treat long-term, chronic conditions. A research team led by Dongsheng Duan, PhD, at the University of Missouri School of Medicine has identified and overcome a barrier in CRISPR gene editing that may lay the foundation for sustained treatments u
Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or 'hiatus' in global warming over the past 15 years were unfounded.
Disk- and rod-shaped molecules are incompatible in coassembly, as the former tend to stack one-dimensionally whereas the latter tend to align in parallel. Because this type of incompatibility can be more pronounced in condensed phases, different-shaped molecules generally exclude one another. We report that supramolecular polymerization of a disk-shaped chiral monomer in nematic liquid crystals c
Darwin proposed that mate choice might contribute to the evolution of cognitive abilities. An open question is whether observing the cognitive skills of an individual makes it more attractive as a mate. In this study, we demonstrated that initially less-preferred budgerigar males became preferred after females observed that these males, but not the initially preferred ones, were able to solve ext
They’ve weathered blistering attacks from the president, the exposure of sensitive sources, and the politicization of classified information.

On Nov. 22, 2014, astronomers spotted a rare event in the night sky: A supermassive black hole at the center of a galaxy, nearly 300 million light years from Earth, ripping apart a passing star. The event, known as a tidal disruption flare, for the black hole's massive tidal pull that tears a star apart, created a burst of X-ray activity near the center of the galaxy. Since then, a host of observa
Observational studies and clinical trials conducted over nearly 40 years reveal the health benefits of eating at least 25g to 29g or more of dietary fiber a day, according to a series of systematic reviews and meta-analyses.
Observations from Gemini Observatory identify a key fingerprint of an extremely distant quasar, allowing astronomers to sample light emitted from the dawn of time. Astronomers happened upon this deep glimpse into space and time thanks to a foreground galaxy acting as a gravitational lens, which magnified the ancient light. The Gemini observations provide critical pieces of the puzzle in confirming
Feature describes newly discovered stabilizing effect of underappreciated 1983 finding that variations in plasma temperature can influence the growth of magnetic islands that lead to disruption of fusion plasmas.
After combining several imaging sources, including hard X-rays and radiowaves, a team now speculates that the telescopes captured the exact moment a star collapsed to form a compact object, such as a black hole or neutron star. The stellar debris, approaching and swirling around the object's event horizon, caused The Cow's remarkably bright glow.
Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or "hiatus" in global warming over the past 15 years were unfounded.
A small percentage of Americans, less than 9 percent, shared links to so-called "fake news" sites on Facebook during the 2016 presidential election campaign, but this behavior was disproportionately common among people over the age of 65, finds a new analysis by researchers at New York University's Social Media and Political Participation (SMaPP) Lab and Princeton University.
Light is the most energy-efficient way of moving information. Yet, light shows one big limitation: it is difficult to store. As a matter of fact, data centers rely primarily on magnetic hard drives. However, in these hard drives, information is transferred at an energy cost that is nowadays exploding. Researchers of the Institute of Photonic Integration of the Eindhoven University of Technology (T
A team of researchers from the Netherlands, Italy and Poland has developed a way to make complex molecules that spontaneously fold like proteins. In their paper published in the Journal of the American Chemical Society, the group describes their approach to manipulating molecules in useful ways, what they discovered, and the ways they believe their results might be used.

Conservatives’ obsession with Alexandria Ocasio-Cortez may seem ridiculous. Ever since the 29-year-old former bartender wrested the Democratic primary nomination from the 10-term incumbent Joe Crowley, right-wing media has fixated on the unapologetically left-wing representative. From her clothes to her nickname to her high school to her childhood home , conservatives seem particularly intent on
Research in mice finds a new molecular mechanism that is essential for maturation of brain function and may be used to restore plasticity in aged brains. Unlike previous research that broadly manipulated brain plasticity and affected the entire brain, this work targets for the first time a specific molecule acting on a single type of neuronal connection to modulate brain function. The findings may
A new bioengineering approach for boosting photosynthesis in rice plants could increase grain yield by up to 27 percent, according to a new study. The approach, called GOC bypass, enriches plant cells with CO2 that would otherwise be lost through a metabolic process called photorespiration. The genetically engineered plants were greener and larger and showed increased photosynthetic efficiency and
An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation's (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF's Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation. Observations made with facilities ranging from
Flat earthers, who believe the Earth is a large disk, may be shocked to find the ship’s navigation is based on a spherical planet A group of people who believe the Earth is flat have announced their “biggest, boldest, best adventure yet”: a Flat Earth cruise scheduled for 2020. The cruise, organized by the Flat Earth International Conference , promises to be a lovely time. Flat earthers – who inc
Singing humpback whales from different ocean basins seem to be picking up musical ideas from afar, and incorporating these new phrases and themes into the latest song, according to a newly published study in Royal Society Open Science that's helping scientists better understand how whales learn and change their musical compositions.
The president of the United States has many faults, but let’s not ignore this one: He cannot write sentences. If a tree falls in a forrest and no one is there to hear it … wait: Pretty much all of you noticed that mistake, right? Yet Wednesday morning, the president did not; he released a tweet referring to “forrest fires” twice , as if these fires were set by Mr. Gump. Trump’s serial misuse of p
Men die earlier than women and commit more acts of violence. But the American Psychological Association did not have a guide for working with males, in part because they were historically considered the norm.
How exactly does gender work? It's not just about our chromosomes, says biologist Karissa Sanbonmatsu. In a visionary talk, she shares new discoveries from epigenetics, the emerging study of how DNA activity can permanently change based on social factors like trauma or diet. Learn how life experiences shape the way genes are expressed — and what that means for our understanding of gender.

Using data from NASA's Kepler space telescope, citizen scientists have discovered a planet roughly twice the size of Earth located within its star's habitable zone, the range of orbital distances where liquid water may exist on the planet's surface. The new world, known as K2-288Bb, could be rocky or could be a gas-rich planet similar to Neptune. Its size is rare among exoplanets—planets beyond ou
Almost from the moment the camera blinked on in the Oval Office, it was clear that President Donald Trump was delivering a Stephen Miller special. The 33-year-old White House speechwriter has a hand in virtually everything the president reads from a teleprompter. But as one of the most strident immigration hawks in the West Wing, Miller has been especially influential over the past two years in s
Eric Young is the president of the union that represents the approximately 30,000 employees of the Federal Bureau of Prisons who are working during the government shutdown. Young’s members, scattered at 122 facilities located in largely rural areas across the country, aren’t being paid and don’t know when their next paycheck will come. Like the leaders of virtually every federal-employee union du
A study published in The FASEB Journal demonstrated that dietary supplementation with omega-3 fatty acids (or fish oils) reduced the rate at which young women lost muscle mass during a period of immobilization.
Whether we pick healthy or indulgent foods may depend on what other foods sit nearby on the grocery shelf, new research suggests. Paradoxically, the nearby presence of an indulgent treat can cause more people to opt for a healthy food, says study coauthor Scott Huettel, professor of psychology and neuroscience at Duke University. Context, in other words, affects food choices. “When people choose
People with schizophrenia can have higher levels of antibodies against Epstein-Barr virus, a herpes virus that causes infectious mononucleosis, new research suggests. Researchers didn’t design the study to pinpoint cause and effect, but say there are at least two possible explanations: Schizophrenia might alter immune systems and make patients more susceptible to the Epstein-Barr virus, or EBV in
Researchers are working to make sure a seeing, hearing, door-opening robot called “ANYmal” can also function in extreme conditions—a mission that takes them to the labyrinth of drains and tunnels below Zurich. Their aim is to determine whether ANYmal—a robot that ANYbotics, an ETH Zurich spin-off company, jointly developed with Robotic Systems Lab—could one day be useful in sewer systems. It migh
Sex helps initiate romantic relationships between potential partners, a new study finds. “Sex may set the stage for deepening the emotional connection between strangers,” says lead author Gurit Birnbaum, a social psychologist and associate professor of psychology at Interdisciplinary Center Herzliya in Israel. “This holds true for both men and women. Sex motivates human beings to connect, regardl
Researchers have overcome a barrier in CRISPR gene editing that may make it an effective way to treat long-term chronic conditions, like Duchenne muscular dystrophy (DMD). The body’s natural defensive ability to fend off viruses inspired CRISPR gene editing. The technology allows scientists to cut out and replace a mutation in the genome to alter DNA sequences, which has the potential to treat a
Circadian (~24-hour) rhythms depend on intracellular transcription-translation negative feedback loops (TTFLs). How these self-sustained cellular clocks achieve multicellular integration and thereby direct daily rhythms of behavior in animals is largely obscure. The suprachiasmatic nucleus (SCN) is the fulcrum of this pathway from gene to cell to circuit to behavior in mammals. We describe cell t
An Medical Research Council funded study published today in the journal Science, has found that astrocytes, previously thought of as just supporting neurons in regulating circadian rhythms, can actually lead the tempo of the body's internal clock and have been shown for the first time to be able to control patterns of daily behaviour in mammals.
Eighty-six Americans lost their lives last year in the Camp Fire, the largest and deadliest wildfire in California’s modern history. More than 11,000 people lived through the blaze but saw their homes destroyed . On Wednesday, President Donald Trump threatened to cut off relief for survivors and communities affected by that blaze, amid an ongoing political standoff with high-ranking California po
There are many times when our cells need to move. Mobile cells guide our body's formation (embryonic development). Immune cells roam to capture unwanted intruders. And healing cells (fibroblasts) migrate to mend wounds. But not all movement is desirable: Tumors are most dangerous when cancer cells gain the ability to travel throughout the body (metastasis). Certain bacteria and viruses can harness
A handful of brain cells deep in the brain may play a surprising role in controlling women's bone density, according to new research. Researchers showed that blocking a particular set of signals from these cells causes female (but not male) mice to build extraordinarily strong bones and maintain them into old age, raising hopes for new approaches to preventing or treating osteoporosis in older wom
How old are each of the stars in our roughly 13-billion-year-old galaxy? A new technique for understanding the star-forming history of the Milky Way in unprecedented detail makes it possible to determine the ages of stars at least two times more precisely than conventional methods, Embry-Riddle Aeronautical University researchers reported Jan. 10 at the American Astronomical Society (AAS) meeting.
Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce 3-D images of cellular microarchitecture. Writing in Light: Science & Applications, Stephan Kellnberger and colleagues at the Institute of Biological and Medical Imaging, now rep
In a new Caltech-led study, researchers from campus and the Jet Propulsion Laboratory (JPL) have analyzed pulses of radio waves coming from a magnetar—a rotating, dense, dead star with a strong magnetic field—that is located near the supermassive black hole at the heart of the Milky Way galaxy. The new research provides clues that magnetars like this one, lying in close proximity to a black hole,

China on Friday broadcast pictures taken by its rover and lander on the moon's far side, in what its space program hailed as another triumph for the groundbreaking mission to the less-understood sector of the lunar surface.
A team of researchers with members affiliated with the University of Auckland, the University of Cambridge, Bertha von Suttner University and the Max Planck Institute for the Science of Human History has found evidence that suggests New Caledonian crows can infer the weight of an object by watching how it behaves in the wind. In their paper published in Proceedings of the Royal Society B, the grou
Repeating bursts of radio waves detected for first time since initial accidental discovery in 2007 Astronomers have detected mysterious, ultra-brief repeating energy bursts from deep space for only the second time in history, and some experts suggested they could be evidence of advanced alien life. The origin of fast radio bursts (FRBs), millisecond-long pulses of radio waves, is unknown, but mos
A president only gets one chance to make his first Oval Office address—making Donald Trump’s reiteration of familiar talking points in a short speech Tuesday night all the more puzzling. Over the course of roughly 10 minutes, Trump brought his case for more spending on border security directly to the American people, saying there is “a growing humanitarian and security crisis at our Southern bord
As the costs of college have climbed, some students have gone hungry. When they’ve voiced frustration , they’ve often been ridiculed : “Ramen is cheap ,” or “ Just eat cereal .” But the blight of food insecurity among college students is real, and a new report from the Government Accountability Office (GAO), a nonpartisan congressional watchdog, highlights the breadth of those affected. There are
Researchers have uncovered part of the explanation for why poor sleep is linked to Alzheimer's disease. They found that older people who have less slow-wave sleep — the deep sleep you need to consolidate memories and wake up feeling refreshed — have higher levels of the brain protein tau. Elevated tau is a sign of Alzheimer's disease and has been linked to brain damage and cognitive decline.
Researchers investigated the impact of parenting practices on the amount of time young children spend in front of screens. They found a majority of parents use screen time to control behavior, especially on weekends. This results in children spending an average of 20 minutes more a day on weekends in front of a screen. Researchers say this is likely because using it as a reward or punishment heigh
Nearly 25 years after the genocide against the Tutsi of Rwanda took the lives of up to one million victims, the offspring of Tutsi survivors, who weren't even born at the time, are among those most affected by trauma.
Bullying rates among middle school students in the spring of 2017 were 18 percent higher in localities where voters had favored Donald Trump than in those that had supported Hillary Clinton, according to a new study.
Singing humpback whales from different ocean basins seem to be picking up musical ideas from afar, and incorporating these new phrases and themes into the latest song, according to a newly published study that's helping scientists better understand how whales learn and change their musical compositions.
A new study has found that — despite its seemingly harsh conditions — the ISS is not causing bacteria to mutate into dangerous, antibiotic-resistant superbugs. The bacteria are instead simply responding, and perhaps evolving, to survive in a stressful environment.
After almost four decades, Leiden and Eindhoven chemists have resolved the discussion about the correct model regarding the simplest chemical reaction in heterogeneous catalysis, which is essential for fuel cells. Using a unique curved platinum surface, Ludo Juurlink and Ph.D. candidate Richard van Lent from Leiden and Michael Gleeson from DIFFER showed which model correctly describes the reaction
Researchers at The University of Manchester's National Graphene Institute in the UK have succeeded in making artificial channels just one atom in size for the first time. The new capillaries, which are very much like natural protein channels such as aquaporins, are small enough to block the flow of smallest ions like Na+ and Cl- but allow water to flow through freely. As well as improving our fund
As a presidential candidate, Donald Trump pledged to reduce illegal immigration from Central America, and since taking office he has paired that vow with professed concerns about not just the flow of asylum seekers into the United States, but the smuggling of drugs and the potential entry of terrorists, too. That, in his telling, is why he wants $5 billion from Congress for a wall along the U.S.

Borders are an invention, and not even an especially old one. Predated by the printing press by a good 200 years, borders are constantly under revision. Even the zone of a border itself, the Supreme Court has held , extends far beyond the technical outline of a nation. Imagine a border as the human-made thing that it is, and it’s no longer surprising that it takes a multitude of forms: a line on

If a doctor told that you needed surgery, you would want to know why — and you’d expect the explanation to make sense to you, even if you’d never gone to medical school. Been Kim, a research scientist at Google Brain, believes that we should expect nothing less from artificial intelligence. As a specialist in “interpretable” machine learning, she wants to build AI software that can explain itself
An international team of researchers led by ANU is helping to build a safe data superhighway for the highly anticipated quantum internet, which promises a new era of artificial intelligence and ultra-secure communication.
On the night of Jan. 9, 2019, the V. M. Blanco 4-meter telescope at the National Science Foundation's (NSF) Cerro Tololo Inter-American Observatory (CTIO), high in the mountains of Chile, will close the camera's shutter on the final image from the Dark Energy Survey (DES) — a survey that has mapped 5,000 square degrees of the heavens, almost one-quarter of the southern sky.
For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort. These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others. Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too. None The divine is supernatural, but religion is very much of this world. The
When Amazon launched its Alexa virtual assistant in 2014, it probably didn't think that a bird would expose a potentially significant legal issue with the device. But an African grey parrot named Rocco, living in Blewbury, England, appears to have done just that.
Fast radio bursts have caused more suspicion about extraterrestrial activity In the 400 years since Galileo Galilei first held a telescope to the heavens, astronomers have laid bare some of the deepest mysteries of the cosmos. They have seen comets crash into planets, found oceans inside moons, and witnessed the shudder of spacetime as black holes collide. But space remains a realm of the unknown
Donald Trump is right that the United States desperately needs more walls. He’s just wrong about their ideal dimension, purpose, and location. The U.S. need not spend tens of billions of dollars on a single barrier extending along the southern border between the United States and Mexico. Rather, what the suddenly wobbly U.S. economy could really use is millions of walls at 90-degree angles. I mea
A new study explores society's relatively poor vaccination coverage through the lens of hysteresis, a phenomenon that describes how systems are dependent on their history. The results show how 'imperfect vaccines' and episodes of public confusion can result in sharp drops in population-wide immunization rates, and how it can take years for those rates to recover. By promoting an individual's choi
Single lens eyes, like those in humans and many other animals, can create sharp images, but the compound eyes of insects and crustaceans have an edge when it comes to peripheral vision, light sensitivity and motion detection. That's why scientists are developing artificial compound eyes to give sight to autonomous vehicles and robots, among other applications. Now, a new report describes the prepa
Many biosensing applications rely on characterization of specific analytes such as proteins, viruses and bacteria, among many other targets, which can be accomplished by using micro- or nano-scale particles. In such biosensors, these particles are coated with a surface chemistry that makes them stick to the target analyte forming clusters in response. The higher the target analyte concentration is
The asteroid that crashed into the Yucatan caused a mile-high tsunami. The wave was 52 times higher and 2,600 times more energetic than the 2004 Indian Ocean tsunami that killed over 227,000 people. Sediment was disturbed 3,700 miles from the site of the crash. None Becoming a fossil is no easy matter. There are a number of conditions that have to be met, according to Paige Williams, author of Th
Today, at the 233rd AAS meeting in Seattle, astronomers from the Sloan Digital Sky Survey (SDSS) announce that they have developed a new tool to find otherwise-hidden galaxy mergers in data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey of SDSS. These results show that by going beyond simple searches for merging galaxies based just on how they look, astronomers will no
Astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode. Through repeated observations of SN 2015cp, a supernova 545 million light years away, the team detected hydrogen-rich debris that the companion star had shed prior to the explosion.
Many stars explode as luminous supernovae when, swollen with age, they run out of fuel for nuclear fusion. But some stars can go supernova simply because they have a close and pesky companion star that, one day, perturbs its partner so much that it explodes.
Italian astronomers have investigated the young open cluster NGC 6530 by conducting a statistical study of its global properties. The research, which provides important insights on the cluster membership, was presented in a paper published December 29 on the arXiv pre-print repository.
On March 11, an instrument aboard the International Space Station detected an enormous explosion of X-ray light that grew to be six times as bright as the Crab Nebula, nearly 10,000 light years away from Earth. Scientists determined the source was a black hole caught in the midst of an outburst — an extreme phase in which a black hole can spew brilliant bursts of X-ray energy as it devours an ava

A team led by researchers at Baylor College of Medicine and the University of Texas at Austin has applied an unconventional approach that used bacteria to discover human proteins that can lead to DNA damage and promote cancer. Reported in the journal Cell, the study also proposes biological mechanisms by which these proteins can cause damage to DNA, opening possibilities for future cancer treatmen
Entomologists have performed a study on the Big Island and found viruses associated with the varroa mite, a parasite of honeybees, have spilled over into the western yellowjacket, a honeybee predator and honey raider. The result is a hidden, yet remarkable, change in the genetic diversity of viruses associated with the larger pathogen community of the mite and wasp, with repercussions yet to be un
The reddish-brown varroa mite, a parasite of honeybees and accidentally introduced in the Big Island of Hawaii in 2007-08, is about the size of a pinhead. Yet, its effects there are concerning to entomologists because the mite is found nearly everywhere honeybees are present.
A confounding new disease is killing beech trees in Ohio and elsewhere, and plant scientists are sounding an alarm while looking for an explanation. Researchers and naturalists in northeastern Ohio report on the emerging 'beech leaf disease' epidemic, calling for speedy work to find a culprit so that work can begin to stop its spread.
Chaetognaths, whose name means "bristle-jaw," can be found all over world, swimming in brackish estuaries, tropical seas and above the deep dark ocean floor. Also known as arrow worms, the creatures have been around since the Cambrian Period, but their precise place in evolutionary history has long eluded scientists. Now, researchers at the Okinawa Institute of Science and Technology Graduate Univ
Newborn falls during the postpartum period are a serious potential adverse event and are almost always a result of maternal fatigue. There is reason to be concerned that well-meaning but overzealous promotion of breastfeeding may increase the risk.

A Canadian-led team of scientists has found the second repeating fast radio burst (FRB) ever recorded. FRBs are short bursts of radio waves coming from far outside our Milky Way galaxy. Scientists believe FRBs emanate from powerful astrophysical phenomena billions of light years away.
Scientists have found the second repeating fast radio burst (FRB) ever recorded. The discovery of the extragalactic signal is among the first, eagerly awaited results from the Canadian Hydrogen Intensity Mapping Experiment (CHIME). The repeating FRB was one of a total of 13 bursts detected over a period of just three weeks during the summer of 2018, while CHIME was in its pre-commissioning phase.
Your knees and your smartphone battery have some surprisingly similar needs, a University of Michigan professor has discovered, and that new insight has led to a "structural battery" prototype that incorporates a cartilage-like material to make the batteries highly durable and easy to shape.
A new analysis of the 2011 census has revealed that social differences among city populations significantly influence how neighbourhoods take shape. Researchers hope that their insights could help councils to make better planning decisions.
Space It's not actually dark and it's definitely not red. If you’ve been looking closely at the pictures of the moon's far side, you could be forgiven for thinking that the far side of the moon is red.
The first ever images taken from the surface of the far side of the moon have been released following the Chinese National Space Administration's (CNSA) successful landing there. The lander Chang'e 4 and rover Yutu 2 follow from Chang'e 3 and the original Yutu rover that were deployed on the moon's near side in 2013.

From sex to sugar to social media, people are in the grip of a wider range of compulsive behaviours. But what is driving them – and what can be done? Addiction was once viewed as an unsavoury fringe disease, tethered to substances with killer withdrawal symptoms, such as alcohol and opium. But now the scope of what humans can be addicted to seems to have snowballed, from sugar to shopping to soci
Brain drain is a terrible phenomenon with a long and ignoble history. Recently, it has occurred in several countries that were doing well even a few years ago. Can it happen here? Many of us who have ever dared to complain about the place we live in have heard the juvenile rebuttal "If you don't like it, why don't you leave?" As it turns out, sometimes people take that advice. When a country's ed
I alt regner Cowi med, at der skal bruges svimlende 23 millioner m3 jord til opfyldningen af de 3,1 millioner kvadratmeter store øer. Hvis det bliver svært at skaffe jord kan det true hele projektets businesscase.
In a four-year study, a group of science faculty finds that student buy-in to a new curriculum, and therefore satisfaction, increases with each successive undergraduate cohort—and learning gains did not suffer. The researchers say the results of their longitudinal study should help encourage college faculty and administration to create, adapt, and support innovative courses for their students.
In 1889, Achille-Claude Debussy, then in his mid-20s, was one of 30 million people to walk through the iron arches of the newly completed Eiffel Tower. Throughout that year, the arches served as the grand entryway to the Exposition Universelle , a world’s fair celebrating the cultural, technological, and colonial prowess of France a century after the revolution. A stunning variety of sights greet
BERLIN—On the Wednesday before Christmas, Christoph Scheuermann apprehensively called up a 99-year-old former member of the anti-Nazi resistance who had been imprisoned during World War II. The Washington bureau chief of Der Spiegel , a German news magazine, needed to ask her a question no journalist wants to reckon with: Did his colleague, a now-disgraced star reporter, invent an interview with
The T.S.A. said it favors floppy-eared dogs over pointy-eared dogs in airport jobs because floppy-eared dogs appear friendlier and less aggressive. There is a scientific explanation behind the perception.
The annals of science fiction are full of visions of the future. Some are techno-utopian like "Star Trek" in which humanity has joined together in peace to explore the cosmos. Others are dystopian, like the World State in "Brave New World." But many of these stories share one thing in common – they envision a time in which humanity has moved past narrow ideas of tribe and nationalism. That assumpt
Scientists have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism. The findings could bring about a better understanding of many cancers' metabolic needs and lead to the development of more effective therapies for squamous cell skin cancer and other forms of epithelial cancer.
Keto diets have attracted a lot of media attention lately, and are becoming quite the rage in wellness circles. But while it might make you lose weight in the short term, it's doing one heck of a number on your body. Fitness and nutrition expert Jillian Michaels walks us through why keto might be a no-no. The 6 Keys: Unlock Your Genetic Potential for Ageless Strength, Health, and Beauty List Pric
With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.
Landscapes can change from day-to-day and year-to-year, and many animals will move about according to resource availability. But do they remember past resource conditions? Just how important is memory and spatial cognition when seeking to understand wildlife movement? Researchers in Etosha National Park, Namibia, examined this question through African elephants.
South Korea and US teams say infertility could be linked to deficiency of a protein in womb A new study has cast light on why some women with endometriosis experience infertility, with scientists saying the finding could lead to new treatment options. Endometriosis is an inflammatory condition in which cells that usually form the lining of the uterus are present elsewhere, such as the ovaries, fa
Irisin, a hormone in the human body that is generated by muscle tissue and is carried throughout the body in the bloodstream, can play a part in Alzheimer's onset and effects. In tests on mice, it has become clear that irisin plays a key part in memory and learning; the removal and subsequent adding back of the hormone showed dramatic changes in memory and learning. Researchers think a supplement
Scientists have developed a combination of monoclonal antibodies that protected animals from all three Ebola viruses that cause human disease. The antibody 'cocktail,' called MBP134, is the first experimental treatment to protect monkeys against Ebola virus (formerly known as Ebola Zaire), as well as Sudan virus and Bundibugyo virus, and could lead to a broadly effective therapeutic.
Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round — an unusual circumstance for a whale species known to migrate across ocean basins.
Even though every dollar spent on soil improvement can save much more in environmental costs down the road, startup costs can sometimes make it hard for farmers to implement best environmental practices. A team of researchers from Rice and North Dakota State universities argues that this is especially true for using biochar, but that the problem can be addressed through well-designed policy.
Astrophysicists have found the first ever evidence of gigantic remains being formed from repeated explosions on the surface of a dead star in the Andromeda Galaxy, 2.5 million light years from Earth. The remains or "super-remnant" measures almost 400 light years across. For comparison, it takes just 8 minutes for light from the Sun to reach us.
There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet's growing population will only further increase the need for animal protein, one of the most resource-intensive types of food to produce.
Bacteria have a number of well-known tricks available to them to adapt to changing environments, such as mutation and sharing snippets of DNA with each other. Less studied is a mechanism that allows bacteria to hedge their bets against rapid environmental changes by fine tuning their use of particular genes or pathways, a process known as "phase variation."
Researchers have found yet another way in which climate change has been detrimental to migrating birds. As European winters have become warmer, pied flycatchers traveling from Africa to reach breeding grounds in the Netherlands are arriving to find that resident great tits have already claimed nesting sites for the season. As a result, the number of flycatchers killed in great tit nests has risen

As a result, the number of flycatchers killed in great
The human nose can distinguish one trillion different scents—an extraordinary feat that requires 10 million specialized nerve cells, or neurons, in the nose, and a family of more than 400 dedicated genes. But precisely how these genes and neurons work in concert to pick out a particular scent has long puzzled scientists. This is in large part because the gene activity inside each neuron—where each
A new study has investigated whether taking vitamin E supplements could affect risk of cancer and found that genetic variations in the gene COMT influenced whether vitamin E decreased or increased risk of developing cancer during and after the study periods.
Deploying a new technique for the first time in the region, geoscientists at the University of Massachusetts Amherst have reconstructed the longest and highest-resolution climate record for the Northeastern United States, which reveals previously undetected past temperature cycles and extends the record 900 years into the past, well beyond the previous early date of 1850.

CRISPR-Cas9 is a revolutionary tool in part because of its versatility: created by bacteria to chew up viruses, it works equally well in human cells to do all sorts of genetic tricks, including cutting and pasting DNA, making pinpoint mutations and activating or inactivating a gene.
One of the greatest superhero movies of all time is Tim Burton’s Batman Returns , a bleak fantasia about three comic-book characters (Batman, Catwoman, and the Penguin) whose identities were forged in trauma, and whose costumed alter egos are exaggerated responses to that pain. Batman Returns came out in 1992, before the costumed-hero drama became Hollywood’s predominant genre. At the time, the m

Children are a wonderful gift, bringing joy, laughter, and love. But, then there are the toys, the sleepless nights, the constant barrage of “why?" questions and the plethora of sticky handprints. For many parents, the decision to have a second child is made with the expectation that two can't be more work than one. But our research on Australian parents shows this logic is flawed: second childre
When it comes to health advice, don’t take Instagram’s word for it. The platform is rampant with misinformation about wellness, argues the Atlantic staff writer Amanda Mull. Behind many fads are Instagram influencers with perceived authority on health and wellness—the majority of whom have no real nutritional training or expertise. Take celery juice, for example.

A notable contender this awards season, Barry Jenkins’s film If Beale Street Could Talk is an exquisite adaptation of James Baldwin’s novel about black intimacy against the backdrop of white racism. The movie also offers viewers a chance to reflect on the work of an author who is as indispensable today as he was in his own lifetime. Baldwin’s literary career spanned four decades, from 1947 to 198
In survival game shows, contestants are whisked away to a foreign location, where they face unfamiliar stresses. To stay in the game, they must adapt to the surroundings and often need to work together with fellow competitors.
The Oscars have always been the guardians of mainstream film taste, for better and for worse. The definition of a “prestige movie,” a term often deployed with derision, is a film made to attract the votes of the Academy of Motion Picture Arts and Sciences (AMPAS) and that thus often tries to win the broadest consensus possible from a group that trends old, white, and male. This approach explains
In 1934, a German pulmonologist wrote a book that contained child-rearing advice that promoted extreme forms of neglect in order to encourage toughness in children. The Nazis later incorporated these principles into a mothers' training program that millions of German women undertook. Some German therapists suggest that the effects of these harsh parenting styles are still being felt by German adu
Until we can design a mind that's superhuman and flawless, we'll have to settle for instilling plain old human values into artificial intelligence. But how to do this in a world where values are constantly evolving? Many of our life choices today would be considered immoral by people in the Middle Ages — or even the 1970s, says Ben Goertzel, whose family personally experienced the sad state of LG
CERN is synonymous with accelerators, designed to boost particles to close to the speed of light. But what if you want to slow down a particle and hold it in place while you study it? Particle traps are devices that use electromagnetic fields to suspend particles – macroscopic or elementary – in stasis long enough to do so. At CERN, experiments such as GBAR use ion traps to capture antihydrogen io
Two international research teams have identified key regulatory networks controlling how plants grow 'outwards', which could help us to grow trees to be more efficient carbon sinks and increase vegetable crop yields.
Eventually, humanity will want to travel to a new solar system to propagate the human race, explore, and maybe find signs of alien life. But our closest neighbor, Proxima Centauri, is so far away that current methods could take tens of thousands of years. How will we surmount this incredible distance and the other challenges associated with interstellar travel? None Alpha Centauri, the closest st

During the European Middle Ages, literacy and written texts were largely the province of religious institutions. Richly illustrated manuscripts were created in monasteries for use by members of religious institutions and by the nobility. Some of these illuminated manuscripts were embellished with luxurious paints and pigments, including gold leaf and ultramarine, a rare and expensive blue pigment
During a visit on Thursday to the nerve center of the Arab world, Mike Pompeo declared that reports of America’s departure from the Middle East under Donald Trump had been greatly exaggerated, and that it was Barack Obama who had abandoned the region—to devastating effect. And yet the irony is that while the conduct of Obama and Trump in the Middle East couldn’t be more different, they’ve in fact

Researchers were able to identify mother's perceived stress during the first year of the child's life as a risk factor for developing overweight in infancy. Researchers found this to have long-lasting effects on girls' weight development in particular.
New research describes a mechanism in a mouse model of asthma that supports the hygiene hypothesis — researchers found that infant mice need a higher exposure to a bacterial endotoxin, compared to adult mice, to avoid developing asthma-like reactions to house dust mites. The hygiene hypothesis suggests that decreased exposure to microbial products in industrialized nations is the main driver of i
Researchers have reviewed medical marketing (the marketing of prescription drugs, disease awareness, laboratory tests and health services to consumers and professionals) over a 20-year period from 1997 through 2016 and found that while it had increased dramatically from about $17.7 billion to $29.9 billion, regulation has not.
Scientists increasingly believe that one of the driving forces in chronic pain — the number one health problem in both prevalence and burden — appears to be the memory of earlier pain.

The microbial metabolite, Urolithin A, derived from a compound found in berries and pomegranates, can reduce and protect against inflammatory bowel disease (IBD). Urolithin A (UroA) and its synthetic counterpart, UAS03, mitigate IBD by increasing proteins that tighten epithelial cell junctions in the gut and reducing gut inflammation in animal models. Tight junctions in the gut barrier prevent ina
Galaxy mergers—in which two galaxies join together over billions of years in sometimes-dramatic bursts of light—aren't always easy for astronomers to spot. Now, scientists from the University of Colorado Boulder have developed a new technique for finding these cosmic couplings in surveys of the night sky.
Gaze skyward from the Southern Hemisphere and it’s hard to miss the Large Magellanic Cloud. The fact that it looks like one of the Milky Way’s spiral arms, albeit smaller, reveals that it’s a small galaxy roughly 30,000 light-years across with a few billion stars. Indeed, any small telescope will show that it’s scattered with glowing nebulae that are punctured by dark dollops of dust. And it isn’

Intentionally "squashing" colloidal quantum dots during chemical synthesis creates dots capable of stable, "blink-free" light emission that is fully comparable with the light produced by dots made with more complex processes. The squashed dots emit spectrally narrow light with a highly stable intensity and a non-fluctuating emission energy. New research at Los Alamos National Laboratory suggests t
Out of the box, crystalline MOFs (metal-organic frameworks) look like ordinary salt crystals. But MOFs are anything but ordinary crystals – deep within each crystalline "grain" lies an intricate network of thin, molecular cages that can pull harmful gas emissions like carbon dioxide from the air, and contain them for a really long time.
Astronomers have found a new exoplanet that could alter the standing theory of planet formation. With a mass that's between that of Neptune and Saturn, and its location beyond the 'snow line' of its host star, an alien world of this scale was supposed to be rare.
Years before the devastating Tohoku earthquake struck the coast of Japan in 2011, the Earth's crust near the site of the quake was starting to stir. Researchers at The University of Texas at Austin are using computer models to investigate if tiny tremors detected near this site could be connected to the disaster itself.
Using the CRISPR gene editing tool, researchers have developed a new way to control and suppress populations of insects, potentially including those that ravage agricultural crops and transmit deadly diseases. The 'precision-guided sterile insect technique' alters key genes that control insect sex determination and fertility. When pgSIT eggs are introduced into targeted populations, only adult ste
A new study has found that astrocytes, previously thought of as just supporting neurons in regulating circadian rhythms, can actually lead the tempo of the body's internal clock and have been shown for the first time to be able to control patterns of daily behavior in mammals.

When people pose the old question about whether a tree falling in an empty forest makes a sound , they presuppose that none of the other plants in the forest are listening in. Plants, supposedly, are silent and unhearing. They don’t make noises, unless rustled or bitten. When Rachel Carson described a spring bereft of birds, she called it silent . But these stereotypes may not be true. According

A team of researchers affiliated with the Max Planck Institute for Evolutionary Anthropology, Yale University and the University of Göttingen, has found that older children are more likely to make seemingly irrational decisions when social comparison is at play. In their paper published in Proceedings of the Royal Society B: Biological Sciences, the group describes experiments they carried out wit
Although sunscreen is critical for preventing sunburns and skin cancer, some of its ingredients are not so beneficial to ocean-dwelling creatures. In particular, sunscreen chemicals shed by swimmers are thought to contribute to coral reef decline. Now, researchers say that one such chemical, octocrylene (OC), which is also in some cosmetics and hair products, accumulates in coral as fatty acid est
Tyrannosaurus rex, renowned for being one of the most fearsome creatures to have ever lived, evolved a bite that was less impressive in relation to its body size than a tiny Galapagos ground finch, scientists say.
Aging bodies undergo biological changes that cause a decline in the function of cells and tissues. However, most studies attempting to identify molecules involved in age-related dysfunctions have focused only on mechanisms based on mRNA transcription, a very important step in gene expression, but nonetheless only part of the complex regulatory mechanisms in our cells.
Researchers have found that the RNA-binding protein PUM2 contributes to the accumulation of defective mitochondria, a key feature of the aging process. Targeting PUM2 in old animals protects against age-related mitochondrial dysfunction.
Termites are commonly regarded as one of the most destructive insect pests, yet its unknown side was recently revealed by a major new study. Researchers have discovered that termites actually help mitigate against the effects of drought in tropical rainforests.
The term dinosaur comes from the ancient Greek root words deinos , or “terrible,” and sauros , or “lizard.” As our understanding of these prehistoric creatures has become more refined over time, attempts to create life-size models of them have, more or less, increased in accuracy and lifelike quality. Of course, many of the thousands of dinosaur statues in the world have been made with an eye mor
Researchers conducted focus groups with students who recently graduated from high school to ask them about their experience with peer groups. Altogether, the participants identified 12 distinct "peer crowds" and ranked them in a social hierarchy. The results show that, compared to past decades, some groups have risen or fallen in the hierarchy, and a couple new groups have emerged. None How do mo
Radio signals could be signs of extraterrestrial life. But, with Brexit and Trump, could they have chosen a worse time to call? Earlier this week, astronomers announced that they had observed repeated bursts of radio waves coming from deep space, with some experts suggesting this could be evidence of alien life . Is this it? Could extraterrestrials finally be trying to contact us? I hope not. Rela
What We’re Following Welcome to day 19 of the government shutdown. Hundreds of thousands of federal workers are about to miss a paycheck. Some are furloughed, while others—from TSA agents to prison guards— are required to show up for work anyway. Federal government workers technically aren’t allowed to strike due to a 1947 law , and with the prospect of the shutdown dragging on for weeks or month
What We’re Following 1. Negotiations to end the U.S.-government shutdown are still stalled as President Donald Trump remains steadfast in his demand for money to build a southern-border wall—a major campaign promise. Even if a physical wall is built, it might not achieve the president’s desired effect. For one, a border is much more than just a membrane separating one location from another, and “
What We’re Following Today It’s Wednesday, January 9. President Donald Trump had lunch with Senate Republicans on Capitol Hill today to talk about the government shutdown, now in its 19th day. Members said the president urged the caucus to stay strong, and described him as “resolute.” Later in the day, Trump reportedly walked out of a meeting with Democratic leaders because they wouldn’t agree to
What We’re Following Today It’s Thursday, January 10, and the partial government shutdown has been going on for 20 days. President Donald Trump visited the southern border in the town of McAllen, Texas, where he continued to push for his proposed wall; before he left, he told reporters he was prepared to declare a national emergency to unlock funding for the project. In a Holding Pattern: Even af
It’s likely you’ve never read, or even heard of, most of the books Atlantic writers have reviewed since the magazine was founded in 1857.

But then, inside the cr
Phineas Gage is considered to be Patient Zero for traumatic brain injury. The story of Gage at the time was that his damaged brain rendered him a different, monstrous person. This wasn't true. Recent studies demonstrate that an injured brain can see an increase in connection in areas associated with touch and learning. Phineas Gage was a railroad foreman in the 19th century. In 1848, while blasti
Last week, many viewers watched Surviving R. Kelly in horror as the documentary highlighted old and new sexual-abuse allegations against the singer.

Typically, when a president wants to make policy, he has to negotiate a deal with Congress. Because that hasn’t worked out for President Donald Trump in securing his border wall, he’s tried to find another way to lock down the $5 billion he wants to build it. “I have the absolute right to do national emergency if I want,” he told reporters on Wednesday. By Thursday night, administration officials

When blue-collar workers go on strike, demands such as wage increases and better hours are usually the objective. But when nearly 8,000 Marriott International employees marched outside hotels for two months in late 2018, one request stood out among the rest: protection against the automated technology that’s remaking the hotel industry. Marriott employees are right to worry. Over the past few yea
As President Donald Trump descends on the border Thursday to further make his case for a wall, back home in Washington congressional Republicans—the ones whose resolve he needs if he’s going to continue his shutdown campaign—are growing more anxious. While the images Trump broadcasts to the nation may bolster his case to his base, these Republicans are left to talk and share doubts among themselv
It was Thursday around lunchtime, and Lindsey Graham was over it. “Right now I am going to the gym,” the South Carolina senator told reporters in the Capitol. “I have never been more depressed about moving forward.” There was reason to be depressed. Thursday was day 20 of the partial government shutdown, and despite the flurry of speeches, meetings, and press releases that had marked these weeks,
Study reveals the Americans who live in states that spend more on tangible "public goods" are happier. This spending makes communities "more livable." Pain of higher property taxes largely balanced out by higher property values and quality of life.

A new map from WalletHub, generated by comparing various federal data, shows the states most affected by the government shutdown. About 800,000 federal employees are furloughed or are working without pay. Government shutdowns have become an increasingly common political tool, but it wasn't until the early 1980s that they started resulting in the closing of federal agencies. None Friday marked the
A spider’s web is more than a trap or a home. It is also an extension of the spider’s senses . By paying attention to vibrations traveling through the silken threads, the arachnid can learn about its surroundings. Certain vibrations might mean ensnared prey. A different frequency might reveal a nearby mate. And since spiders extrude their webs from their bodies, they can also change the stiffness

When Nancy Pelosi and Chuck Schumer finished their rebuttal to President Donald Trump’s Oval Office address on Tuesday, it was not entirely clear what Democrats were hoping to accomplish. The dual remarks seemed largely like a rehash of familiar talking points. But their effectiveness emerged Thursday when President Trump traveled to McAllen, Texas. On Tuesday, Pelosi, the House speaker, had said
After weeks of to-ing and fro-ing about timetables, Donald Trump is keeping his promise—sort of, with adjustments. On Friday, the military announced that it was beginning the process of withdrawing troops from Syria. This a few weeks after the president shocked Washington in December by declaring that he intended to get out, starting “now,” having vowed to do so on the campaign trail more than tw
Donald Trump hasn’t talked about the opioid epidemic much recently. So when he used the peerless pulpit of the Oval Office to discuss it on Tuesday night, it could have been an opportunity to rally the public and to provide meaningful solutions. His words framed the urgency of the situation, which for many Americans may have been out of sight in the past few months. “Our southern border is a pipe
On Tuesday, Donald Trump delivered a televised Oval Office address, hoping to marshal the gravitas of the presidency to get his way on a border wall. The gambit was doomed from the start. Insofar as prime-time addresses from the White House have power, it is rooted in the public’s belief that there is dignity in the office, that its occupant possesses moral authority, and that he or she would ask
President Donald Trump may now be talking more about steel than cement, but his proposed border wall remains the Rosetta Stone for understanding both his conception of the presidency and his political strategy. Nothing better illustrates Trump’s political calculus than his determination to build the wall, a goal that most Americans consistently oppose in polls, even at the cost of shutting down t
