Scientists steer the development of stem cells to regenerate and repair organs
Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily structures, a critical step in eventually regenerating and repa.....»»
The microbiology of honey: A sweet symphony of life
Honey, a complex substance made by a variety of species of bees, is often celebrated for its sweetness and health benefits. In fact, humans have been using honey, sometimes called liquid gold, for generations to soothe cold symptoms and promote wound.....»»
Simulations of hominin Lucy help show how long distance running evolved in modern humans
A team of natural scientists, musculoskeletal specialists, and evolutionary biologists affiliated with several institutions in the U.K., working with a colleague from the Netherlands, has found via simulations, that the famous early hominin Lucy, cou.....»»
Sea snakes regain advanced color vision, recovering a complex trait once lost to evolutionary time
Nine species of sea snakes have now been identified as having regained the genetic requirements for advanced color vision, demonstrating that once a complex trait has been lost to evolutionary time, it may be regained in some way......»»
Giant sloths and mastodons coexisted with humans for millennia in Americas, new discoveries suggest
Sloths weren't always slow-moving, furry tree-dwellers. Their prehistoric ancestors were huge—up to 4 tons (3.6 metric tons)—and when startled, they brandished immense claws......»»
Environmental groups challenge update to California"s low-carbon transportation rules
A coalition of environmental groups challenged California's leading climate regulator on Wednesday, alleging that a recent update to a leading climate program will create additional pollution in the state's San Joaquin Valley......»»
Here’s what we learned driving Audi’s new Q6 and SQ6 electric SUVs
Audi's mid-sized electric SUV is now on sale in the US, and we've tested it. Audi provided flights from Washington, DC, to San Francisco and accommodation so Ars could drive the Q.....»»
Scientists document rich biodiversity along underexplored Chilean coastline
An international team of scientists on board a recent Schmidt Ocean Institute R/V Falkor (too) expedition surveyed nearly 20 methane seeps, some of which are new discoveries, and four submarine canyon systems previously never before seen by humans......»»
NASA payload aims to probe moon"s depths to study heat flow
Earth's nearest neighboring body in the solar system is its moon, yet to date, humans have physically explored just 5% of its surface. It wasn't until 2023—building on Apollo-era data and more detailed studies made in 2011–2012 by NASA's automate.....»»
Arctic snow shows up to 71 times more PFAS during sunny months
PFAS refers collectively to the thousands of man-made chemicals that take a very long time to break down in nature. None of these substances occur naturally—also called forever chemicals, and several are suspected of negatively affecting humans and.....»»
San Diego is relaxing its no-gas rule for new city buildings: To environmentalists, it"s "a giant loophole"
Local environmentalists are criticizing San Diego for retreating on a two-year-old policy that requires all new and significantly renovated city buildings to rely entirely on electricity instead of gas......»»
Are threat feeds masking your biggest security blind spot?
Security teams that subscribe to threat feeds get lists of known malicious domains, IPs, and file signatures that they can leverage to blacklist and prevent attacks from those sources. The post Are threat feeds masking your biggest security blind spo.....»»
New software unlocks secrets of cell signaling, showing realistic simulations
Researchers at University of California San Diego have developed and tested a new software package, called Spatial Modeling Algorithms for Reactions and Transport (SMART), that can realistically simulate cell-signaling networks—the complex systems.....»»
How a giant prehistoric elephant skull helped untangle an evolutionary mystery
About 400,000 years ago, early humans in Europe, Asia and Africa lived alongside giant straight-tusked elephants, far bigger than their modern-day cousins. Their evolution has long been a mystery to paleontologists, but an extraordinary, enormous and.....»»
Melting sea ice in Antarctica causes ocean storms, scientists say
The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday......»»
Ice is melting, seas are rising—how scientists are tracking the changes
Will the sea rise by 20 cm or 3 meters by 2100? This is obviously an interesting question to answer. Predicting the sea level in 75 years requires precise calculations and correct models of the melting of the ice from, e.g., Greenland. To do so, rese.....»»
Russian oil spill contaminates 50km of Black Sea beaches
Russia Wednesday expanded an operation to clean up thousands of tonnes of oil that spilt into the sea and contaminated 50 kilometers of beaches after tanker ships were wrecked in a storm......»»
Dogs demonstrate ability to match voices to familiar humans
Researchers at ELTE Department of Ethology, Hungary designed an experiment to investigate whether dogs can recognize their owners based on pre-recorded speech. The results provided the first evidence that dogs are capable of voice-based individual-le.....»»

A monkey mapping study could boost conservation of animal species that share their habitats with humans......»»
NASA missions spot cosmic "wreath" displaying stellar circle of life
Since antiquity, wreaths have symbolized the cycle of life, death, and rebirth. It is fitting then that one of the best places for astronomers to learn more about the stellar lifecycle resembles a giant holiday wreath itself......»»
