A new study describes the strength of diabolical ironclad beetle exoskeletons. The findings could help designers create hardier vehicles and...
Scientists analyzed genomic information from over 6,000 samples of SARS-CoV-2, the coronavirus behind the COVID-19 pandemic. Results show that early measures in states such as California and Washington were effective at limiting viral spread in the early phases of the pandemic.
By examining the guano of the fringe-lipped bat (Trachops cirrhosus), biologists encountered surprising results about its eating habits and foraging abilities.
Poop is full of secrets. For scientists, digging into feces provides insights into animal diets and is particularly useful for understanding nocturnal or rare species. When animals eat, prey DNA travels all the way through animal digestive tracts and comes out again. Poop contains very precise information about the prey species consumed. At the Smithsonian Tropical Research Institute (STRI), a...
As insulators, metal oxides—also known as ceramics—may not seem like obvious candidates for electrical conductivity. While electrons zip back and forth in regular metals, their movement in ceramic materials is sluggish and difficult to detect.
No one has yet found the first stars.
Ancient Maya in the once-bustling city of Tikal built sophisticated water filters using natural materials they imported from miles away, according to the University of Cincinnati.
Today, the Energy Futures Initiative (EFI) and Stanford University released "An Action Plan for Carbon Capture and Storage in California: Opportunities, Challenges, and Solutions," a report providing policymakers with options for near-term actions to deploy carbon capture and storage (CCS) to meet the state's climate goals.
Researchers at Empa and ETH Zurich succeeded in developing a material that works like a luminescent solar concentrator and can even be applied to textiles. This opens up numerous possibilities for producing energy directly where it is needed, i.e. in the use of everyday electronics.
New research shows how a combination of imagery from mobile phones, drones and satellites can be used to clamp down on banana threats. The images of varying resolutions are fed into a platform "trained" through machine learning to identify banana crops and analyze threats with 97% overall accuracy. The findings were published in the ISPRS Journal of Photogrammetry and Remote Sensing.
The Codex Cospi is one of the few Aztec 'books' in the world and it is kept at Bologna University Library. A new research project will investigate with unprecedented detail the painting techniques and tools with which it was made.
Venezuela's opposition warned of a potential "environmental catastrophe" Thursday as a damaged oil tanker threatened to spill 1.3 million barrels of crude into waters separating Venezuela from Trinidad and Tobago.
Orange skies, winds gusting up to 70 mph, smoke tornadoes and hazardous air. While it could be an apocalyptic scene out of a movie, it's become the reality of Colorado's wildfire season.
The Dutch government said Thursday it is ordering poultry farms to keep their birds indoors after six wild swans were found recently dead and tests on two of the birds came back positive for a highly pathogenic strain of bird flu.
During a blip in time in the late Jurassic, a dinosaur that weighed no more than a chinchilla flung itself from tree to tree, spread its wings and tried to soar. In theory, it sounds beautiful -- an early attempt at flight before birds figured out the blueprint.In practice, it was chaotic.The dinosaur, Yi qi, only barely managed to glide, stretching out and shimmying its skin-flap, downy-feathered...
A 'safety net' made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team of researchers analyzing the new goals for biodiversity being drafted by the UN's Convention on Biological Diversity (CBD).
Repurposed solar panel research could be the foundation for a new ultrahigh-resolution microdisplay. The OLED display would feature brighter images with purer colors and more than 10,000 pixels per inch.
Ancient Maya in the once-bustling city of Tikal built sophisticated water filters using natural materials they imported from miles away, according to new research. A multidisciplinary team of anthropologists, geographers and biologists identified quartz and zeolite, a crystalline compound consisting of silicon and aluminum, that created a natural molecular sieve. Both minerals are used in modern...
Computational astrophysics study modeled for the first time faint supernovae of metal-free first stars, yielding carbon-enhanced abundance patterns for star formation. Study investigated formation of first stars and the origin of elements heavier than hydrogen, helium, lithium.
As insulators, metal oxides - also known as ceramics - may not seem like obvious candidates for electrical conductivity. While electrons zip back and forth in regular metals, their movement in ceramic materials is sluggish and difficult to detect.
Scientists have discovered a way to control the growth of twisting, microscopic spirals of materials just one atom thick. The continuously twisting stacks of two-dimensional materials built by a team create new properties that scientists can exploit to study quantum physics on the nanoscale.
Virologists have identified a critical role played by a cellular protein in the progression of Hepatitis C virus infection, paving the way for more effective treatment. No vaccine currently exists for Hepatitis C virus infection, which affects more than 130 million people worldwide and nearly 250,000 Canadians. Antivirals exist but are expensive and not readily available in developing countries,...
Movement in animals is complex. Little has been known about how spinal inhibitory interneurons work to silence other neurons and related muscle groups in coordination with the active muscle groups across changing speeds. Now a research team has discovered in a study of zebrafish that there is a very orderly relationship between when these critical inhibitory neurons are born, their participation...
Tiny movements in Earth's outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now detecting these long-hidden microquakes in the growing mountain of seismic data.
When humans age, they tend to favor small circles of meaningful, already established friendships rather than seek new ones. People are also more likely to lean toward positive relationships rather than ones that bring tension or conflict. These behaviors were thought to be unique to humans but it turns out chimpanzees, one of our closest living relatives, have these traits, too. The study shows...
Researchers develop a one-pot, low temperature catalytic method to turn polyethylene polymers into alkylaromatic molecules.
In this week's issue of our environment newsletter, we look at ways to reduce the waste around trick-or-treating and some of the hurdles to widespread electric-vehicle adoption in Canada.
While it could be an apocalyptic scene out of a movie, it has become the reality of Colorado's wildfire season. One of Colorado’s smaller fires exploded late Wednesday from 30 square miles (78 square kilometers) to 196 square miles (508 square kilometers) and closed Rocky Mountain National Park. Fire officials say it has so far burned 265 square miles (686 square...
Researchers say chimpanzees and humans share same pattern of social ageingThere is more that comes with older age than greying hair and wrinkled skin. When humans reach their later years, they favour more established friends and their social circle is pared down.Now, for what appears to be the first time, scientists have seen the same behaviour in another species. More than two decades of...
When we started using plastics about 70 years ago, not much thought—if any—was given to the implications of their lifespan and the fact that they can take centuries to decompose. Consequently, as plastics have diversified and become easier to manufacture, the planet is now straddling some 8.3 billion tons of the stuff—almost every bit of plastic ever produced—without enough technology or...
No new friends and no drama.
Scientists at the University of Wisconsin-Madison have discovered a way to control the growth of twisting, microscopic spirals of materials just one atom thick.
A new USC-led study suggests a change to the developmental—and evolutionary—story of the pituitary gland.
Nearly three decades have passed since world leaders agreed to reverse biodiversity loss. It hasn't gone according to plan. This year, the current decade of biodiversity conservation targets are set to expire well short of the goal line. The world needs to change strategies if we are to have any hope for biodiversity. A global group of scientists has provided advice for a more successful...
A critically endangered species of frog seems to have a bright future after conservationists in Chile launched a rescue campaign that has produced 200 offspring.
Policy changes can help to fight stigmas of multiracial Americans, one of the fasting growing minority groups in the United States according to a new study.
Over the last century, the compound ammonium nitrate has been involved in at least 30 disasters and terrorist attacks.
Hydraulic fracturing has boomed in the U.S. over the past decade, but unless you live near it, you may not realize just how close fracking wells can be to homes and schools. In Colorado, the wellbore—the hole drilled to extract oil or gas—can be 500 feet from someone's house under current state rules. In some states, like Texas, drilling can be even closer.
