Scientists develop culture system to unlock secrets of the skin microbiome
The human skin is home to a wide variety of bacteria. The composition of the community of bacteria—called the "skin microbiota"—has serious implications for skin health. A healthy balance between different species of bacteria on the skin often tr.....»»
The moon might be older than scientists previously thought; a new study shines light on its history
A physicist, a chemist and a mathematician walk into a bar. It sounds like the start of a bad joke, but in my case, it was the start of an idea that could reshape how scientists think about the history of the moon......»»
Lab work digs into gullies seen on giant asteroid Vesta by NASA"s Dawn
Pocked with craters, the surfaces of many celestial bodies in our solar system provide clear evidence of a 4.6-billion-year battering by meteoroids and other space debris. But on some worlds, including the giant asteroid Vesta that NASA's Dawn missio.....»»
Scientists observe "negative time" in quantum experiments
Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter......»»
Saturday Citations: Chicxulub meteorite found guilty; Good news and bad news for LLMs
It's the last week before Christmas and not a creature is stirring, not even a mouse model bred to exhibit characteristics of ADHD for in vivo studies of central nervous system stimulants. This week, we reported on the discovery of the world's oldest.....»»
Introducing perceptein, a protein-based artificial neural network in living cells
Westlake University in China and the California Institute of Technology have designed a protein-based system inside living cells that can process multiple signals and make decisions based on them......»»
Two stars may be orbiting each other near a supermassive black hole in our Milky Way galaxy
Scientists have spotted what appear to be two stars whipping around each other near the supermassive black hole at the center of our Milky Way galaxy......»»
Tom Holland says he doesn’t ‘know anything about’ the Christopher Nolan movie he’s starring in
The actor has been famous for letting secrets about his projects slip, so it might be for the best if he's kept in the dark......»»
Report: Every iPhone model will be able to update to iOS 19, but some iPads left behind
Thanks to a usually-reliable tip off from iPhoneSoft, we may already know device compatibility for Apple’s next major operating system updates coming next year. The report says that every iPhone model that currently supports iOS 18 will also sup.....»»
Wireless antennas harness light to decode cellular communication signals
Monitoring electrical signals in biological systems helps scientists understand how cells communicate, which can aid in the diagnosis and treatment of conditions like arrhythmia and Alzheimer's......»»
"Living" ceramics utilize bacteria for gas sensing and carbon capture
A team of materials scientists and chemists at ETH Zürich has developed a way to make "living" ceramics that can detect small amounts of formaldehyde and capture carbon dioxide from the air. In their project, reported in the journal Advanced Materia.....»»
Cyanobacteria research unlocks potential for renewable plastics from carbon dioxide
Scientists at The University of Manchester have achieved a significant breakthrough in using cyanobacteria—commonly known as "blue-green algae"—to convert carbon dioxide (CO2) into valuable bio-based materials......»»
Ferns" ancient resilience aids modern ecosystem recovery after disasters
Scientists have suggested an updated framework for the role of ferns in environmental recovery from disaster. Instead of competing with other organisms, ferns may act as facilitators that ease the way for other plants and animals to re-establish them.....»»
Volunteers should not become friends with patients, say Norwegian researchers
When a volunteer supports a patient, a special and often rather unequal relationship can develop between the helper and the person receiving the help. Researchers have now investigated this relationship and offer guidance on finding the right balance.....»»
Biosensors mimic human olfactory system to discriminate between very similar odors
The human olfactory system discriminates between thousands of odors by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different intensities, and the same odorant can activate more th.....»»
Avalanches, icy explosions and dunes: NASA is tracking New Year on Mars
Instead of a winter wonderland, the Red Planet's northern hemisphere goes through an active—even explosive—spring thaw. While New Year's Eve is around the corner here on Earth, Mars scientists are ahead of the game: The Red Planet completed a tri.....»»
Apple warns spyware targets via ‘threat notifications,’ offers these next steps
Did you know that Apple, for years, has had a system and process for sending ‘threat notifications’ to users of suspected spyware attacks? Here’s what that means, and new details on the guidance Apple gives users with a compromised device......»»
Shedding light on snow"s crucial role in Earth"s climate system
EU researchers are braving extreme Arctic conditions to shed light on snow's crucial role in Earth's climate system......»»
Neural networks unlock potential of high-entropy carbonitrides in extreme environments
The melting point is one of the most important measurements of material properties, which informs potential applications of materials in various fields. Experimental measurement of the melting point is complex and expensive, but computational methods.....»»
Intense ribbons of rain also bring the heat, scientists say
The environmental threat posed by atmospheric rivers—long, narrow ribbons of water vapor in the sky—doesn't come only in the form of concentrated, torrential downpours and severe flooding characteristic of these natural phenomena. According to a.....»»
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.....»»
