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...
