Tracing the rapid evolution of spermatogenesis across mammals
Evolutionary pressure across male mammals to guarantee the procreation of their own offspring led to a rapid evolution of the testicle. Bioinformatic studies—conducted by an international team of researchers led by Prof. Dr. Henrik Kaessmann from t.....»»
Human cases of H5N1 confirmed in California amid rapid dairy spread
The CDC confirmed two new bird flu cases, bringing the human tally to 17. Two California dairy farm workers who had contact with H5N1-infected cows have contracted an H5 avian inf.....»»
Study suggests statistical "noise" affects perceived evolutionary rates
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, in evolutionary terms,.....»»
Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather a dynamic mix of water a.....»»
Bottlenose dolphins "smile" at each other while playing, research shows
Dolphins are extremely playful, but little is known about how they—and other marine mammals—communicate during playtime. New research published October 2 in the journal iScience shows that bottlenose dolphins (Tursiops truncates) use the "open mo.....»»
SVS Ultra Evolution Pinnacle speakers: warm, sweet, effortless sound
The SVS Evolution Pinnacle speakers are excellent in so many ways that it might seem hard to believe. But these could well be the only speakers I ever need......»»
New insights into sauropod evolution: Discovery of tail clubs in India
A new University of Michigan study of dinosaur fossils from India has revealed that the sauropod dinosaur Kotasaurus yamanpalliensis wielded a bony tail club......»»
Could APIs be the undoing of AI?
Application programming interfaces (APIs) are essential to how generative AI (GenAI) functions with agents (e.g., calling upon them for data). But the combination of API and LLM issues coupled with rapid rollouts is likely to see numerous organizatio.....»»
Octopuses work together with fish to hunt—and the way they share decisions is surprisingly complex
A new study published in Nature Ecology & Evolution lifts the veil on what happens when octopuses and fish hunt together. As it turns out, this cross-species relationship is more complex than anyone expected......»»
SpyCloud Connect delivers automated remediation of compromised identities
SpyCloud released new hosted automation solution, SpyCloud Connect, which delivers custom-built automation workflows to Information Security (InfoSec) and Security Operations (SecOps) teams. The solution enables rapid automation of SpyCloud’s suite.....»»
Plant lineage study provides insights into the ecological and evolutionary effects of different reproductive strategies
Hang Sun's group from Kunming Institute of Botany, Chinese Academy of Sciences has demonstrated the ecological and evolutionary effects of changes in plant reproductive strategies on phylogenetic evolution. The study is published in the journal Scien.....»»
Researchers crack a key problem with sodium-ion batteries for electric vehicles and grid energy storage
Lithium-ion batteries have long dominated the market as the go-to power source for electric vehicles. They are also increasingly being considered for storage of renewable energy to be used on the electric grid. However, with the rapid expansion of th.....»»
AI trained on evolution"s playbook develops proteins that spur drug and scientific discovery
A new artificial intelligence model developed by researchers at The University of Texas at Austin paves the way for more effective and less toxic treatments and new preventive strategies in medicine. The AI model informs the design of protein-based t.....»»
Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
LG TVs start showing ads on screensavers
LG's TV business is heightening focus on selling ads and tracking. Enlarge / LG's 2024 G4 OLED TV. (credit: LG) Last month, Ars Technica went on a deep dive into the rapid growth of ads in TV software. Less than three.....»»
New evolutionary model revises the origins of biodiversity
An international team of scientists has made a discovery that could reshape our understanding of how global biodiversity evolved. By reconstructing the evolution of species over the past 45 million years, researchers found that the geographic origins.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
How a butterfly invasion minimizes genetic diversity
Until a few years ago, the butterfly known as the southern small white could barely be found north of the Alps. That was before a Europe-wide invasion that brought a huge increase in the insect's distribution—at the same time as a rapid decrease in.....»»
Quantum sensing approach captures nanoscale electrochemical evolution in battery
Battery performance is heavily influenced by the non-uniformity and failure of individual electrode particles. Understanding the reaction mechanisms and failure modes at nanoscale level is key to advancing battery technologies and extending their lif.....»»
