Scientist identifies signaling underlying regeneration
The mystery of why salamanders can regenerate a lost limb, but adult mammals cannot has fascinated observers for thousands of years. Now, a team of scientists has come a step closer to unraveling that mystery with the discovery of differences in mole.....»»
Jellyfish regenerate lost tentacles, and now we know how
Jellyfish regeneration looks a lot like that of amphibians and other animals. Enlarge (credit: Gerard Soury) The mythical Hydra may have been able to grow one of its many heads back every time it suffered a decapitation,.....»»
Research finds climate-dependent dispersal limitation plays an important role in mountain soil microbiome
Microbial communities are highly diverse, yet the mechanisms underlying microbial community assembly are not well understood. In 1967, Daniel Janzen hypothesized that low climatic variability along elevational gradients results in greater constraints.....»»
Elusive cytonemes guide neural development, provide signaling "express route"
St. Jude Children's Research Hospital scientists found that cytonemes (thin, long, hair-like projections on cells) are important during neural development. Cytonemes connect cells communicating across vast distances but are difficult to capture with.....»»
Novel path of intercellular signal sharing discovered in zebrafish experiments
Researchers at the University of Exeter, U.K., have discovered intricate mechanisms of ligand–receptor complex transport via specialized protrusions transporting signaling components between cells, challenging the conventional understanding of cell.....»»
New study reveals five new species of soft-furred hedgehogs from Southeast Asia
A new study led by scientists at the Smithsonian's National Museum of Natural History identifies five new species of soft-furred hedgehogs from Southeast Asia......»»
Human brain cells put much more energy into signaling
Signaling molecules help modulate the brain's overall activity. Enlarge (credit: Westend61) Indian elephants have larger brains than we do (obviously). Mice have a higher brain-to-body mass ratio, and long-finned pilot w.....»»
2023"s extreme storms, heat and wildfires broke records—a scientist explains how global warming fuels climate disasters

Horizon scan identifies 15 most pressing issues for conservation, including invertebrate decline and marine ecosystems
Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year......»»
Study identifies Florida"s potential invasive species threats
In a first-of-its-kind study for North America, scientists accumulated a list of potential invasive species for Florida, and researchers deemed 40 pose the greatest threat......»»
New method tags cells with location coordinates for single-cell studies
When a scientist wants to study individual cells at the molecular level within an organ like the heart or brain, they usually break the tissue up to analyze the cells. This provides rich detail about gene activity, but doesn't retain information abou.....»»
DNSFilter Malicious Domain Protection identifies risky domains
DNSFilter announced the addition of a new Malicious Domain Protection feature to its protective DNS software, building on its machine learning capabilities. This feature bolsters DNSFilter’s defenses providing better visibility and protection a.....»»
Scientist show trees in wetter regions are more sensitive to drought
This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spo.....»»
Webb identifies tiniest free-floating brown dwarf
Brown dwarfs are sometimes called failed stars, since they form like stars through gravitational collapse, but never gain enough mass to ignite nuclear fusion. The smallest brown dwarfs can overlap in mass with giant planets. In a quest to find the s.....»»
Political science meets physical science: The shared concept of stability
In a Perspective, a biophysical chemist, Kenneth J. Breslauer, and his brother, a political scientist, George W. Breslauer, explore the parallelisms between the concept of stability as it is used in their respective fields. The Perspective is publish.....»»
SAFE Materiality Assessment Module identifies top cyber risk scenarios
Safe Security announced its new SAFE Materiality Assessment Module, enabling security and risk leaders to achieve SEC compliance by estimating and tracking materiality of cyber incidents. Safe Security’s materiality module is based on the fully.....»»
NASA"s Perseverance rover deciphers ancient history of Martian lake
Marking its 1,000th Martian day on the Red Planet, NASA's Perseverance rover recently completed its exploration of the ancient river delta that holds evidence of a lake that filled Jezero Crater billions of years ago. The six-wheeled scientist has to.....»»
Underwater architects: The "burrowing effect" of foraminifera on marine environments
Dr. Dewi Langlet, a scientist at the Evolution, Cell Biology and Symbiosis Unit at the Okinawa Institute of Science and Technology (OIST), studies foraminifera, single-cell organisms with shells made of calcium carbonate. He and his collaborators hav.....»»
Ukraine has lost almost 20% of its scientists due to the war, study finds
Until the early morning of February 24, 2022, Ukrainian scientist Olena Iarmosh did not believe there would be a Russian invasion of Ukraine. Iarmosh grew up and had settled in Kharkiv, her beloved city in Eastern Ukraine and only 40 km away from the.....»»
Coral reefs in peril from record-breaking ocean heat
