Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they created a gene expression atlas that identifies rare stem cel
阅读全文Researchers from the University of Waterloo discovered that measuring long-term stress through children’s hair samples can reveal early signs of mental health risks in those living with chronic physical illnesses. Children with persistently high cortisol
阅读全文Scientists at UC San Diego have identified a new drug, ION224, that could transform the treatment of MASH, a dangerous form of fatty liver disease tied to obesity and diabetes. By blocking a key liver enzyme, the drug reduces fat and inflammation, halting
阅读全文Preschoolers with ADHD are often given medication right after diagnosis, against medical guidelines that recommend starting with behavioral therapy. Limited access to therapy and physician pressures drive early prescribing, despite risks and reduced effec
阅读全文Eating more like the Mediterranean—rich in vegetables, legumes, fruits, and olive oil—may do more than just support heart health. A new King’s College London study suggests it also protects against gum disease by lowering inflammation markers in the blood
阅读全文QROCODILE has set record-breaking sensitivity in the search for dark matter, detecting signals at energy levels once thought impossible. These results may be just the first step toward finally capturing direct evidence of the universe’s hidden mass.
阅读全文People taking semaglutide report far fewer obsessive thoughts about food, with cravings dropping sharply and mental health improving. This new research hints the drug may offer freedom from the constant distraction of food noise.
阅读全文Some people taking Ozempic, Wegovy, or Mounjaro notice that food suddenly tastes sweeter or saltier, and this subtle shift in flavor perception appears tied to reduced appetite and stronger feelings of fullness. In a study of more than 400 patients, rough
阅读全文Switching clocks twice a year disrupts circadian rhythms in ways that harm health. Stanford scientists found permanent standard time would reduce obesity and stroke rates nationwide, making it the strongest option over permanent daylight saving time or se
阅读全文Behind the dusty clouds of the Cigar Galaxy lies a dazzling powerhouse of star formation, where stars are being born ten times faster than in the Milky Way. Astronomers using the Hubble Space Telescope have uncovered massive super star clusters in its cor
阅读全文NASA’s Perseverance rover has delivered its most compelling clue yet in the search for life on Mars. A rock sample called “Sapphire Canyon,” taken from the Bright Angel formation in Jezero Crater, shows unusual mineral patterns known as “leopard spots” th
阅读全文Scientists have uncovered how the brain reroutes its communication pathways depending on whether it’s processing something new or recalling the familiar. By fine-tuning the balance between different inhibitory circuits, the brain flexibly shifts between r
