Mechanism by which exercise strengthens bones and immunity
Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well a.....»»
Nano-confinement may be key to improving hydrogen production
Researchers at Lawrence Livermore National Laboratory (LLNL) have discovered a new mechanism that can boost the efficiency of hydrogen production through water splitting......»»

Gnatalie is the only green-boned dinosaur found on the planet. She will be on display in LA
The latest dinosaur being mounted at the Natural History Museum in Los Angeles is not only a member of a new species—it's also the only one found on the planet whose bones are green, according to museum officials......»»
"A history of contact": Geneticists are rewriting the narrative of Neanderthals and other ancient humans
Ever since the first Neanderthal bones were discovered in 1856, people have wondered about these ancient hominins. How are they different from us? How much are they like us? Did our ancestors get along with them? Fight them? Love them? The recent dis.....»»
How Some People’s Body Resists Getting COVID
When scientists exposed people to the virus that causes COVID, only a subset got sick. Studying them could offer clues to immunity.....»»
DNA analyses show the plague may have caused the downfall of Stone Age farmers
Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research.....»»

Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Notepad’s spellcheck and autocorrect are rolling out to everybody after 41 years
It's still bare-bones by most standards, but Notepad has evolved a lot recently. Testing spellcheck in the latest version of Windows Notepad......»»
Pear-derived discovery: A genetic mechanism to fortify crops against drought
A recent study has shed light on a critical genetic mechanism that boosts plants' ability to withstand drought. The research uncovers the role of the transcription factor PbERF3, native to wild pears, which works in concert with the protein PbHsfC1a.....»»
Scientists uncover conserved mechanism of pericentric heterochromatin initiation in vertebrates
A study published in Nature on July 4 by Prof. Zhu Bing from the Institute of Biophysics of the Chinese Academy of Sciences has shed light on the conserved mechanism responsible for the initiation of pericentric heterochromatin in vertebrates......»»
New theory reveals fracture mechanism in soft materials
A new theory has finally deciphered the physical mechanisms of fracture in soft materials. This discovery could soon lead to new, defect-free materials that are more resistant and durable as well as environmentally friendly. The article "Elastic inst.....»»
High-altitude cave used by Tibetan Buddhists yields a Denisovan fossil
Cave deposits yield bones of sheep, yaks, carnivores, and birds that were butchered. Enlarge / The Baishiya Karst Cave, where the recently analyzed samples were obtained. (credit: Dongju Zhang’s group (Lanzhou University)).....»»
Simulations demonstrate potential mechanisms of intermediate-mass black hole formation in globular clusters
Joint research led by Michiko Fujii of the University of Tokyo demonstrates a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed st.....»»

Researchers reveal a new mechanism of hyaluronic acid with a specific molecular weight to improve host inflammation
Previous studies on the function of glycosaminoglycans have primarily focused on improving host physiological indices. However, little attention has been paid to the material basis and mechanism of their mediated improvement of host health by gut mic.....»»
Droplets that swim toward dissolution could inspire fluid microbots
Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop fluid micro robots......»»
New insights into the interaction of femtosecond lasers with living tissue
Nonlinear light microscopy has revolutionized our ability to observe and understand complex biological processes. However, light can also damage living matter. Yet, the mechanism behind the irreversible perturbation of cellular processes by intense l.....»»
