Instead of blocking hackers, a new cybersecurity defense approach actually welcomes them. The method, called DEEP-Dig (DEcEPtion DIGging), ushers intruders into a decoy site so the computer can learn from hackers' tactics. The information is then used to train the computer to recognize and stop future attacks.
Wearing hearing aids may delay cognitive decline in older adults and improve brain function, according to promising new research. University of Melbourne researchers have tested the use of hearing aids in almost 100 adults aged 62-82 years with hearing loss. After 18 months of hearing aid use, researchers found speech perception, self-reported listening disability and quality of life had significa
A research team demonstrated for the first time that the number of soldiers in a trematode colony depends on the local invasion threat, showing that such societies produce greater standing armies in areas of greater threat. This has big implications for understanding how animal societies determine their resource allocation.
If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases, and live longer—eat less food. That's the conclusion of a new study by scientists from the US and China that provides the most detailed report to date of the cellular effects of a calorie-restricted diet in rats. While the benefits of caloric restriction have long been known, the new results
Properly designed and maintained outdoor green space has the potential to reduce violent crime and gun violence, to make communities safer and keep residents healthier, a new study suggests. Conversely, green space that is poorly designed and inadequately maintained can help crime take root and spread.
On Wednesday, prominent academic journal The Lancet retracted a call for help that had ostensibly been written by Chinese health workers fighting the coronavirus outbreak in Wuhan. The problem? The journal now says the two authors of the original article lied, claiming to witness horrifying scenes in understaffed hospitals firsthand. "Questions regarding the validity of this correspondence were b
Picture the following sacred but unhygienic scene: Pilgrims from a dozen countries converge on one small city. They stay in cramped hotels, using communal toilets and eating meals together. For their main ritual, they converge on the tomb of a woman, the sister of a holy man, and as they get closer, they feel with rising intensity grief over her death and the deaths of her kin. The grief is a com

JACEP Open, a new official open access journal of the American College of Emergency Physicians (ACEP), explores coronavirus (COVID-19) concerns in two new analyses. The first paper explores risk factors for transmission while the second outlines broad public health concerns amplified during an outbreak.
The impacts of the coronavirus on people's health and daily life, stock markets, and businesses illustrate the increasingly interconnected nature of the challenges facing governments around the world. Putting systemic thinking at the centre of policymaking will be essential to address these issues in an era of rapid and disruptive change, according to a new joint report by IIASA and the Organisati
Recent days have brought reports of shoppers clearing out supermarket shelves from Wuhan and Hong Kong to Singapore and Milan in response to the spread of coronavirus. This behaviour is often described as "panic buying."
As of February 2020, the number of people infected with the coronavirus Covid-19 has surpassed 80,000, with nearly 2,700 deaths. Efforts to contain the outbreak have led to full or partial quarantines of several Chinese provinces and cities, as well as other countries that have been hit. The movement restrictions that have been implemented currently affect 500 million people.
Given that news about the deadly COVID-19 coronavirus outbreak is practically unavoidable at this point, it shouldn't come as a surprise that a 2017 infographic about proper respirators use from the CDC is resurfacing.

Philosopher Peter Singer cites his top three ethical issues in the world today as: extreme poverty; climate change, which is related to poverty; and the way humans treat animals. Any rational being should be interested in trying to understand how they ought to live, and whether they are doing things that are right or wrong. Singer suggests asking yourself important questions. When it comes to ext
A trillion trees is a lot, but would be woefully inadequate to address the global warming crisis, according to Democrats and climate scientists who said Republican backers of a tree-planting plan are using it to distract attention from the need to phase out fossil fuel use.

Transportation produces a sizable amount of greenhouse gas emissions, largely by using petroleum to power internal combustion engines. Alternatives –- for example, organic materials such as grasses to produce fuels or electricity –- could avoid petroleum use altogether.
Black carbon particles—more commonly known as soot—absorb heat in the atmosphere. For years, scientists have known that these particles are affecting Earth's warming climate, but measuring their exact effect has proved elusive.
NASA has selected a new space-based instrument as an innovative and cost-effective approach to maintaining the 40-year data record of the balance between the solar radiation entering Earth's atmosphere and the amount absorbed, reflected, and emitted. This radiation balance is a key factor in determining our climate: if Earth absorbs more heat than it emits, it warms up; if it emits more than it ab
Scientists developed a new method to convert carbon dioxide to methane with an electric field at low temperatures. In comparison to previous methods, this new method can produce any amount of methane whenever necessary. Because methane is a valuable gas which can be used to generate heat and electricity, this method could be exploited to help reduce the use of fossil fuels and prevent global warmi

When disease epidemics and outbreaks occur, conspiracy theories often emerge that compete with the information provided by public health officials. A Dartmouth-led study in Science Advances finds that information used to counter myths about Zika in Brazil not only failed to reduce misperceptions but also reduced the accuracy of people's other beliefs about the disease.
Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far remained elusive. Now, researchers have systematically mapped skin cells and their genetic programs, creating a detailed molecular atlas of the skin in its complexity.
How does a developing embryo, which is initially round, tell left from right? This basic process is still poorly understood. However, investigating unusual cases can help shed light on how this process occurs in animals. More than a century ago, German biologist Dr. H. C. Delsman described unusual left-right (L-R) patterning in the tadpole-like tunicate Oikopleura dioica. Now, researchers at Osaka

Discovery suggests screening for bug that creates toxin could prevent thousands of cases Scientists have raised fresh hopes for preventing bowel cancer after discovering that a common gut bacterium drives genetic mutations that can cause the disease. Researchers found that a toxin secreted by a particular strain of the microbe E coli creates distinct mutations in DNA, which contribute to an estim
Weather is an ever-present force in consumers' daily lives, yet there is little marketing research on how it affects consumers and businesses. A new UBC Sauder School of Business study reveals that sunny and snowy conditions trigger consumers to mentally visualize using products associated with the respective weather, which leads to consumers placing a higher value on them. Researchers also found
Senckenberg researcher Dr. Torben Riehl and his colleague Dr. Bart De Smet from Ghent University in Belgium have named a previously unknown species of deep-sea crustacean in honor of the band Metallica. The deep-sea scientist from Frankfurt suggested the name to pay tribute to his rock idols. At the same time, the researchers want to raise awareness. This creature has been discovered in the abyss
Vegetable oil biofuels are increasingly used as an alternative to fossil fuels despite the growing controversy regarding their sustainability. In a study, researchers investigated the effect of palm-oil biodiesel on greenhouse gases for the entire life cycle.

For half a century, scientists who have developed models of how ecological communities function have arrived at an unsettling conclusion. Their models' predictions—seen as classic tenets of community ecology—suggested that mutualistic interactions between species, such as the relationship between plants and pollinators, would lead to unstable ecosystems.
Liberia was the epicenter of a high-profile Ebola outbreak in 2014-15, which led to more than 10,000 deaths in West Africa. But for all the devastation the illness caused, it could have been worse without an innovative, volunteer-based outreach program Liberia's government deployed in late 2014. A study shows how much that program, consisting of door-to-door canvassing by community volunteers, spr
Researchers have used cryo-electron microscopy to elucidate for the first time the structure and function of a very small enzyme embedded in cell membranes. This enzyme builds complex sugar trees that are subsequently attached to other membrane proteins. The findings could accelerate the development of new, protein-based medications.

The tiny forefoot of a lizard of the genus Anolis was trapped in amber about 15 to 20 million years ago. Every detail of this rare fossil is visible under the microscope. But the seemingly very good condition is deceptive: The bone is largely decomposed and chemically transformed, very little of the original structure remains. The results, which are now presented in the journal PLOS ONE, provide i
For the first time, researchers have used an advanced analytical technique known as dual-comb spectroscopy to rapidly acquire extremely detailed hyperspectral images. By acquiring a full spectrum of information for each pixel in a scene with high sensitivity and speed, the new approach could greatly advance a wide range of scientific and industrial applications such as chemical analysis and biomed
The underlying cause for why some regions are home to an extremely large number of animal species may be found in the evolutionary adaptations of species, and how they limit their dispersion to specific natural habitats. This was shown in a new study by researchers from the University of Copenhagen and the Smithsonian Institution. The research sheds new light on an old controversy regarding the or
Now researchers are presenting guidelines for how active matter, such as cells and microorganisms, can best be studied using machine learning techniques. The guidelines can help others navigate the new field, which can significantly improve research in active matter.

Since the 1970s, scientists have been trying to knot molecules together to create new, custom-made mechanical properties, which will give rise to new materials. Today, researchers have developed a simple and effective technique for tying knots in molecules, and have for the first time observed the changes in properties that result from these interlockings. The results open up new perspectives for
The development of classical and quantum information–processing technology calls for on-chip integrated sources of structured light. Although integrated vortex microlasers have been previously demonstrated, they remain static and possess relatively high lasing thresholds, making them unsuitable for high-speed optical communication and computing. We introduce perovskite-based vortex microlasers an
Scientists have been attempting to come up with an equation to unify the micro and macro laws of the Universe; quantum mechanics and gravity. We are one step closer with a paper that demonstrates that this unification is successfully realized in JT gravity. In the simplified toy model of the one dimensional domain, the holographic principle, or how information is stored on a boundary that manifest
As experimental proposals go, this one certainly doesn't lack ambition. First, take a black hole. Now make a second black hole that is quantum entangled with it, which means that anything that happens to one of the black holes will seem to have an effect on the other, regardless of how far apart they are. The rest sounds a bit easier, but a lot weirder. Feed some information into the first black
"Kangaroo care," the practice of holding babies using skin-to-skin contact, is safe and beneficial for babies born with congenital heart defects, a new study shows. This kind of holding—between a baby wearing just a diaper and a parent with a bare chest—has scientifically proven physiological benefits for infants, researchers say. They're less likely to intermittently stop breathing. Their heart

Nature Communications, Published online: 27 February 2020; doi:10.1038/s41467-020-14960-3 CRISPR homing gene drives are highly invasive and can fail due to the rapid evolution of resistance. Here the authors present TARE drive, inspired by naturally occurring selfish genetic elements, which is less vulnerable to resistance and can potentially be confined to a target population.
Nature has provided a great deal of inspiration for computer scientists developing search algorithms and ways to solve complicated problems with as little computing power as possible. Ant colonies, beehives, bat hunting, and now slime mold foraging can be used as models on which an algorithm can be constructed.
Organic halides are important building blocks in synthesis, but their use in (photo)redox chemistry is limited by their low reduction potentials. Halogen-atom transfer remains the most reliable approach to exploit these substrates in radical processes despite its requirement for hazardous reagents and initiators such as tributyltin hydride. In this study, we demonstrate that α-aminoalkyl radicals

Teenagers' Career Aspirations and the Future of Work is based on the latest PISA survey of 500,000 15-year-olds from 41 countries. • Young people's career aspirations have remained largely frozen since 2000. • Ge
Researchers at the Chinese Academy of Sciences in Beijing have started analyzing data collected by the country's Yutu-2 Moon rover's ground-penetrating radar. The instrument peered 40 meters (131 feet) below the lunar surface — and found it was sitting on top of a mountain of fine dust. China's Chang'e 4 lander touched down on the far side of the Moon in January 2019, becoming the first man-made
Yes, these won't fit in your back pocket, but no smartphone will be able to take photos like a camera with the right lens. (ShareGrid via Unsplash/) One of the best things about DSLR and mirrorless cameras (and their main advantage over your smartphone ) is their ability to be specific. While taking photos with a device you carry around in your pocket all day is easy, shooting with a dedicated ca
In a groundbreaking discovery, researchers at Children's Hospital of Philadelphia (CHOP) developed a new imaging method that allows scientists to view the enteric nervous system (ENS) — a key part of the human colon — in three dimensions by making other colon cells that normally block it invisible. The ENS has previously only been visible in thin tissue slices that provide limited clinical infor
Chill out with some cold brew. (Matt Hoffman via Unsplash/) Getting your caffeine fix in warm weather can be complicated. Hot coffee or tea is unappealing when you're already sweating, and a trip to the cafe for something cold is exhausting if you haven't already had a cup. Though cold-brew coffee may carry an air of mystery, it is easier than ever to make at home. Doing so will save you time, mo
The outer Solar System object (486958) Arrokoth (provisional designation 2014 MU 69 ) has been largely undisturbed since its formation. We studied its surface composition using data collected by the New Horizons spacecraft. Methanol ice is present along with organic material, which may have formed through irradiation of simple molecules. Water ice was not detected. This composition indicates hydr
The great mystery of consciousness is why matter lights up with felt experience. After all, we are composed of particles indistinguishable from those swirling around in the sun; the atoms that compose your body were once the ingredients of countless stars in our universe's past. They traveled for billions of years to land here—in this particular configuration that is you—and are now reading these
Wenlock Edge, Shropshire: Hierarchies, dependence and relationships determine the birds' comings and goings The bird feeder hangs from a branch a few metres from the hide. It has been placed there and filled with seed by the National Trust in woodland next to an old quarry above the road along Wenlock Edge. There's a path from the car park that passes the hide and it's a favourite place for child
CRISPR-Cas9 gene editing provides a powerful tool to enhance the natural ability of human T cells to fight cancer. We report a first-in-human phase 1 clinical trial to test the safety and feasibility of multiplex CRISPR-Cas9 editing to engineer T cells in three patients with refractory cancer. Two genes encoding the endogenous T cell receptor (TCR) chains, TCRα ( TRAC ) and TCRβ ( TRBC ), were de

Does brain asymmetry for speech and music emerge from acoustical cues or from domain-specific neural networks? We selectively filtered temporal or spectral modulations in sung speech stimuli for which verbal and melodic content was crossed and balanced. Perception of speech decreased only with degradation of temporal information, whereas perception of melodies decreased only with spectral degrada
A targeted therapy drug used for breast and kidney cancers may also extend progression-free survival for patients with advanced head and neck cancer who are at high risk for recurrence after standard treatment. Patients enrolled in a randomized phase II trial who received the mTOR inhibitor everolimus were more likely to be cancer-free a year after therapy than those who took a placebo, and the be
A research team led by a scientist at the University of California, Riverside, has found that brains treated with certain drugs within a few days of an injury have a dramatically reduced risk of developing epilepsy later in life. The development of epilepsy is a major clinical complication after brain injury, and the disease can often take years to appear.
The Minor Planet Centre has just announced that the Earth has been orbited by a second moon for the past three years or so. But while excitement about the discovery is growing, it is important to keep in mind that this moon isn't as impressive as our main satellite. It is extremely faint—it is estimated to be only between one and six metres across—and won't be with us for much longer.
If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases, and live longer — eat less food.

Ecological differentiation is correlated with taxonomic diversity in many clades, and ecological divergence is often assumed to be a cause and/or consequence of high speciation rate. However, an analysis of 30,074 genera of living marine animals and 19,992 genera of fossil marine animals indicates that greater ecological differentiation in the modern oceans is actually associated with lower rates
If a philosopher starts speaking about elementary particles, run. Pinterest I recently discovered panpsychism. That's the idea that all matter—animate or inanimate—is conscious, we just happen to be somewhat more conscious than carrots. Panpsychism is the modern elan vital. When I say I "discovered" panpsychism, I mean I discovered there's a bunch of philosophers who produce pamphlets about it. H
This month: The impulse to "fix" intersex infants with invasive surgeries is facing increased and, some would argue, long-overdue scrutiny. As doctors, parents, and intersex people face decisions that may affect their long-term health, researchers grapple with defining and measuring outcomes.
Ecologically diverse clades came to dominate the modern oceans because they were better buffered against the successive mass extinctions events which reshaped marine animals over evolutionary time — not because of their higher rates of speciation, according to a new study.
Consuming extra virgin olive oil has proved to have protecting effects for the health, especially due to its antioxidant content. However, there are not many studies on whether it is the best oil to use when cooking. A study by the University of Barcelona stated this kind of oil keeps the levels of antioxidants -regarded as health- when used for cooking in the Mediterranean cuisine. These results

These smaller handheld vacs, known commonly as "dust busters
For centuries, flow visualization has been the art of making fluid motion visible in physical and biological systems. Although such flow patterns can be, in principle, described by the Navier-Stokes equations, extracting the velocity and pressure fields directly from the images is challenging. We addressed this problem by developing hidden fluid mechanics (HFM), a physics-informed deep-learning f

The nature of consciousness seems to be unique among scientific puzzles. Not only do neuroscientists have no fundamental explanation for how it arises from physical states of the brain, we are not even sure whether we ever will. Astronomers wonder what dark matter is, geologists seek the origins of life, and biologists try to understand cancer—all difficult problems, of course, yet at least we ha
Fast-charging batteries typically use electrodes capable of accommodating lithium continuously by means of solid-solution transformation because they have few kinetic barriers apart from ionic diffusion. One exception is lithium titanate (Li 4 Ti 5 O 12 ), an anode exhibiting extraordinary rate capability apparently inconsistent with its two-phase reaction and slow Li diffusion in both phases. Th

Years before smart homes became a thing, I replaced all the switches in our house with computerized switches. At first, it was just a way to add wall switches without pulling new wire. Over time, I got more ambitious. The system runs a timer routine when it detects no one is home, turns on the basement light when you open the door, and lights up rooms in succession on well-worn paths such as bedr
The Cold Classical Kuiper Belt, a class of small bodies in undisturbed orbits beyond Neptune, is composed of primitive objects preserving information about Solar System formation. In January 2019, the New Horizons spacecraft flew past one of these objects, the 36-kilometer-long contact binary (486958) Arrokoth (provisional designation 2014 MU 69 ). Images from the flyby show that Arrokoth has no
The 2013 Universal Credit welfare reform appears to have led to an increase in the prevalence of psychological distress among unemployed recipients, according to a nationally representative study following more than 52,000 working-age individuals from England, Wales, and Scotland over nine years between 2009-2018, published as part of an issue of The Lancet Public Health journal on income and heal
It can be hard to comprehend the true scope of something as disastrous as the opioid epidemic. Perhaps that's why it's been compared with falling 747s and crashing cars . But in fact, knowing exactly how many people have perished is crucial to stopping the deaths. That's why Elaine Hill and Andrew Boslett, economists at the University of Rochester, were so concerned when they found that many pote
O n February 27 , 1860, Abraham Lincoln stood before a simple wooden lectern in New York City's Cooper Union and delivered one of the most consequential speeches of his life. He offered a ringing condemnation of slavery, an unapologetic appeal to the righteous position of the free states, and a clear-eyed assessment of the dark and dangerous years ahead. When the tall prairie lawyer began this sp

The New Horizons spacecraft's encounter with the cold classical Kuiper Belt object (486958) Arrokoth (provisional designation 2014 MU 69 ) revealed a contact-binary planetesimal. We investigated how Arrokoth formed and found that it is the product of a gentle, low-speed merger in the early Solar System. Its two lenticular lobes suggest low-velocity accumulation of numerous smaller planetesimals w
With prescription drug costs continuing to grow, lawmakers on both sides of the aisle have proposed modest reforms, including pegging drug prices to an international index. But the moment might be ripe for an even bolder idea: letting the federal government get into the business of generic drug manufacturing.
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Beihang University have developed an octopus-inspired soft robotic arm that can grip, move, and manipulate a wide range of objects. Its flexible, tapered design, complete with suction cups, gives the gripper a firm grasp on objects of all shapes, sizes and textures — from eggs to iPhones to large exer
It's bigger than a plant. (Stan Horaczek /) Venture into the stereo department of any brick-and-mortar department store and it feels like entering a time warp. So many of the systems seem stuck where they were decades ago, with neon lights that glow and flash from behind oversized buttons and dials. Exaggerated grills and tubes promise mega bass in all caps. They shout "PARTY" louder than an obno
The first cinematic adaptation of H. G. Wells's The Invisible Man came in 1933 , when the height of special effects involved props dangling from wires and a special velvet suit . Almost 90 years have passed, and many invisible men (and women ) have come and gone, but it's comforting to see that in Leigh Whannell's latest take on the horror icon, the simplest bits of camera trickery are still the
For more than five years, University of Utah air quality sensors have hitched rides on TRAX light rail trains, scanning air pollution along the train's Red and Green Lines. Now the study, once a passion project of U researchers, has become a state-funded long-term observatory, with an additional sensor on the Blue Line into Sandy and Draper and additional insights into the events that impact the S
After President Donald Trump appeared to exert what military lawyers call "command influence" over yet another Justice Department prosecution—this time that of his ally Roger Stone—Attorney General William Barr politely asked the president to be quiet and let him do his job. Barr got kudos across the political spectrum for standing up to the president and living to tell the tale, and still appare
Two tree species native to the Northeast have been found to be structurally sound for use in cross-laminated timber (CLT) – a revolutionary new type of building material with sought-after sustainability characteristics, according to research by a University of Massachusetts Amherst timber engineer.
I'm sitting in an MIT conference on AI in drug discovery/development as I write this. One of the speakers here (Mathai Mammen, J&J/Janssen) just made a good point – not a new one, but a solid one that deserves some thought. He called for "bilingual" people, by which he means people who have some fluency in data science and some fluency in one or more of the various fields that make up drug resear
While older adults, defined as those 65 and older, make up the largest percentage of cancer patients and survivors, this group is not adequately represented in clinical trials, research at the University of Cincinnati has shown.
University Hospitals in Cleveland was one of the sites for a national study published Feb. 25 in Journal of the American Medical Association which found 'Fast Breast MRI' detected significantly more cancers than digital breast tomosynthesis (3-D mammography) in average-risk women with dense breast tissue.
The unsaturated fats in fingerprints can reveal their age, a new proof-of-concept study shows. It's information that could potentially tie a suspect to a crime scene. Chemist Paige Hinners was using a computer algorithm to objectively analyze the degradation and spread of fingerprint ridges over time—potentially a way to determine the age of a fingerprint—when she noticed something else in her da
L ast month, Juan Guaidó appeared in Washington in the role of political totem. Venezuela's main opposition leader—the man who is recognized by that country's National Assembly, millions of his fellow citizens, and several dozen foreign countries as the rightful president of Venezuela—was one of the special guests at the State of the Union address. President Donald Trump welcomed Guaidó as living
Around 3,300 years ago, the port city of Ugarit was a vibrant urban centre, located strategically on the overland network linking Egypt with Asia Minor and on the route between Persia and India in the east and Greece and Cyprus in the west. The city's origins date back to 3000BC and the first alphabet and alphabetic writing system are believed to have developed there in the 14th century BC.

In just over a month, the YouTubers behind the account "The Hacksmith" have built a half-scale Cybertruck so powerful that it can win against a full-sized Ford F-150 pickup truck in a tug of war. In a video uploaded today, the team of crafty Canadian engineers showed off what their adorable take on Tesla's brutalist stainless steel monstrosity can do. It can Tokyo drift around corners in the snow
In the absence of a federal mandate, some local governments and institutions are stepping up. (Unsplash/Pixabay/DepositPhotos/) In 2018, the United Nations' Intergovernmental Panel on Climate Change set a deadline : Snuff greenhouse gas emissions 45 percent by 2030 to keep warming from creeping past 1.5 degrees Celsius, the threshold beyond which lie the worst consequences of an overheated planet
Researchers in this study estimated the potential water conservation and financial savings generated by eliminating running water for hand scrubbing before surgery in favor of exclusive use of an alcohol-based scrub at a large ophthalmic surgical hospital.
Project Blitz, a coalition of Christian right groups founded by former Republican congressman, Randy Forbes, began as a way to introduce pro-Christian legislation. Bills include faith-based adoption discrimination and mandating that public schools use "In God We Trust" on signage. This year, 226 pieces of anti-transgender legislation, many backed by The Blitz, have been introduced. In 1861, Rever
In the last few months, a number of questions have come in asking if NASA has attributed Earth's recent warming to changes in how Earth moves through space around the Sun: a series of orbital motions known as Milankovitch cycles. What cycles, you ask? Milankovitch cycles include the shape of Earth's orbit (its eccentricity), the angle that Earth's axis is tilted with respect to Earth's orbital pl
The size of glass used for serving wine can influence the amount of wine drunk, suggests new research from the University of Cambridge, funded by the National Institute of Health Research (NIHR). The study found that when restaurants served wine in 370ml rather than 300ml glasses they sold more wine, and tended to sell less when they used 250ml glasses. These effects were not seen in bars.
