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.
The first direct evidence of white dwarf stars solidifying into crystals has been discovered by astronomers at the University of Warwick, and our skies are filled with them.

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

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

While the Agriculture Department continues to inspect domestic meat and poultry, the F.D.A. has reduced inspections of fruits, vegetables and other foods.
An analysis concluded that Earth's oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago, a finding with dire implications for climate change.
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

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

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.

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

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 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

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.

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.

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

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.
Data from the Gaia satellite has revealed that the oldest stars in the Milky Way are crystallising as they cool down, a process that will take billions of years

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.

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.

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.

An elephant never forgets. This seems to be the case, at least, for elephants roaming about Namibia, looking for food, fresh water, and other resources.
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.

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.
Among the social insects, bees have developed a strong and rich social network, where busy worker bees tend to the queen, who in turn, controls reproduction for the benefit of the hive.

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."

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.

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
