Slow Response to Bird Flu in Cows Worries Scientists
The H5N1 virus is a long way from becoming adapted to humans, but limited testing and tracking mean we could miss danger signs.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»

Scientists use drones to track white sharks along California beaches
The forecast at the beach today is cloudy, with a chance of sharks. At least, that's the forecast that researchers at UC Santa Barbara would like to be able to provide. They're leading a project to predict when and where great white sharks show up ne.....»»
Machine learning accelerates discovery of high-temperature alloys
In a study recently published in Engineering, scientists from the University of Science and Technology Beijing, Guangdong Ocean University, and AiMaterials Research LLC have demonstrated a novel method to accelerate the discovery of refractory high-e.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Developing an effective cyberwarfare response plan
In this Help Net Security interview, Nadir Izrael, CTO at Armis, discusses how AI has transformed cyberwarfare by amplifying attacks’ scale and sophistication. Izrael emphasizes the need for AI-powered defenses and proactive cybersecurity strat.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Sloth survival under threat due to climate change, study finds
A new PeerJ study has revealed that sloths, the famously slow-moving creatures of Central and South America, may face existential threats due to climate change. The research, conducted by scientists studying the metabolic response of sloths to rising.....»»
On remote Greek island, migratory birds offer climate clues
Gently holding a blackcap warbler in his palm, ornithologist Christos Barboutis blew on its feathers to reveal the size of its belly: a good indicator of how far the bird can migrate......»»
NASA"s Artemis science instrument gets tested in moon-like sandbox
On Sept. 9 and 10, scientists and engineers tested NASA's LEMS (Lunar Environment Monitoring Station) instrument suite in a "sandbox" of simulated moon regolith at the Florida Space Institute's Exolith Lab at the University of Central Florida in Orla.....»»
Transforming caragana waste into nutritious ruminant feed
In an advance for agricultural waste management, scientists from the Chinese Academy of Sciences have devised a method to convert Caragana korshinskii Kom. waste, a common forestry byproduct in China, into a potential ruminant feed. The research, pub.....»»
First lunar farside samples from Chang"e-6 mission analyzed
A team of Chinese scientists has studied the first lunar farside samples brought back by the Chang'e-6 mission. The findings mark a significant milestone in lunar exploration science and technical exploration capability. The study was published in Na.....»»
These 3D-printed pipes inspired by shark intestines outperform Tesla valves

Scientists uncover a critical component that helps killifish regenerate their fins
Spontaneous injuries like the loss of a limb or damage to the spinal cord are impossible for humans to repair. Yet, some animals have an extraordinary capacity to regenerate after injury, a response that requires a precise sequence of cellular events.....»»
Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
Model predicts 2024 tick cases in Australian pets
For the first time, University of Queensland scientists have been able to make a prediction about the severity of upcoming tick seasons to help vet surgeries and pet owners prepare......»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Bird study shows that grounded running styles conserve energy
A small team of biologists and animal movement specialists in the Netherlands and the U.K. has found that birds such as the emu have a grounded running style at medium speeds, allowing them to conserve energy compared to the ungrounded running style.....»»
Mysterious orca group near Chile tracked down, revealing newly discovered hunting skills
