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.....»»
Study sheds new light on mechanism of robust motility of flagellated bacteria
Flagellated bacteria are propelled by the rotation of helical flagellar filaments, each with a flagellar motor at its base. Taking Escherichia coli (E. coli) as an example, each cell has 3–7 flagella whose rotation as a helical bundle enables the c.....»»
Scientists 3D print a robotic hand with human-like bones and tendons
As a layer is printed, an optical scan IDs flaws and corrects them in the next layer. Enlarge / The 3D-printed hand made via the new method. (credit: ETH Zurich/Thomas Buchner) Have you ever wondered why robots are unabl.....»»
Research reveals molecular mechanism of asymmetric calcium-sensitive receptor activation
Calcium-sensing receptors (CaSRs), widely distributed in tissues and organs such as parathyroid glands, intestines, bones and kidneys, sense the concentration of calcium ions in the blood and maintain the calcium balance in the human body. CaSR is so.....»»
Children"s spelling skills found to improve when teaching integrates movement
A new study from the University of Copenhagen's Department of Nutrition, Exercise and Sports shows that children who use their bodies to 'shape' letter sounds improve their spelling skills more than those who receive traditional classroom instruction.....»»
Judge tosses social platforms’ Section 230 blanket defense in child safety case
Judge: Section 230 doesn’t cover platform design defects allegedly harming kids. Enlarge (credit: ljubaphoto | E+) This week, some of the biggest tech companies found out that Section 230 immunity doesn't shield them f.....»»

For years, John Hancock has made the Apple Watch available for (almost) free to customers participating in its Vitality Plus life insurance program. Now, this offer has been expanded to include the latest Apple Watch Series 9, Apple Watch Ultra 2, an.....»»
How green algae count cell divisions illuminates key step needed for the evolution of multicellular life
An international research team led by James Umen, Ph.D., member, Donald Danforth Plant Science Center has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division. Chlamyd.....»»
The unsafe Safeguard Mechanism: How carbon credits could blow up Australia"s main climate policy
A time bomb is ticking inside the Albanese government's climate policy. When it explodes, Australia will fall short of its climate targets and leave a gaggle of investors shirtless......»»
Crumpled sheets reveal a mechanism for glassy relaxations
We often crumple a scrap piece of paper into a ball before throwing it. This mundane action, however, creates a unique complex system with surprising mechanical properties. Take a thin plastic sheet such as cellophane and try it yourself. While a reg.....»»
Research explores molecular basis of ventilator-induced diaphragm weakness
A study, published in PNAS Nexus, presents evidence that mitochondrial fragmentation is a proximal mechanism underlying ventilator-induced diaphragm dysfunction (VIDD)—and identifies a possible therapeutic to limit diaphragm atrophy during a stay.....»»
Identifying a silicon transporter to improve the yield of rice
Silicon (Si) is abundant in terrestrial environments and accounts for 0.1% to 10% of a plant's dry weight. Certain plant species show high levels of Si accumulation, and research has identified high Si accumulation as a protective mechanism against a.....»»
Microsoft Authenticator suppresses suspicious MFA notifications
Microsoft has quietly rolled out a new mechanism that shields users of its mobile Authenticator app from suspicious (and annoying) push notifications triggered by attackers. Preventing attacks relying on MFA fatigue When faced with MFA-protected acco.....»»
The cell"s "read–write" mechanism: Researchers uncover how instructions for gene expression are relayed
The "read–write" mechanism by which cells replicate and use chemical instructions for expressing genes has been uncovered by RIKEN researchers. The quality and quantity of gene expression correlates not only with instructions by transcription facto.....»»
A new trail to exoplanets: Team successfully detects ammonia isotopologues in atmosphere of cold brown dwarf
They reveal the origin of wine, the age of bones and fossils, and they serve as diagnostic tools in medicine. Isotopes and isotopologues—molecules that differ only in the composition of their isotopes—also play an increasingly important role in a.....»»
