As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells。 By calming this cellular “overdrive,” researchers restored the stem cells’ youthful function, dramatically boosting their ability to regenerate and produce balanced blood cell
Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive。 These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly iron-triggered collapse。 New drugs remove that protection, causing the cells to self-destruct
People confide almost everything to their phones
Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease。 A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced。 Eve
Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses—the group behind diseases like polio, myocarditis, encephalitis, and even the common cold—to reproduce inside human cells。 The team captured, in unprecedented detail, how viral RNA recruits both viral and human proteins to assemble the m
These bookshelf speakers are excellent for music playback, but you'll want to stick with a soundbar for theater-shaking surround sound
Scientists may have uncovered a surprising secret behind why life exists at all。 A new study suggests that the Universe’s fundamental constants — the deep physical rules that govern everything from atoms to stars — appear to sit within an incredibly narrow “sweet spot” that allows liquids to flow properly inside living cells。 Even tiny shifts in th
A casual conversation between graduate students helped spark a breakthrough in aging research at Mayo Clinic。 Researchers discovered that tiny synthetic DNA molecules called aptamers can selectively attach to senescent “zombie cells,” which are linked to aging, cancer, and neurodegenerative disease。 The method could eventually help scientists ident
A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers stumbled upon a bizarre genetic code in a microscopic pond organism。 Instead of following the near-universal “rules” of life, this newly identified protist rewrites how genes signal their end。 This unexpected discovery challe
Scientists revisiting mysterious 540-million-year-old microfossils from Brazil have overturned a major idea about early animal life。 What were once thought to be trails left behind by tiny worm-like creatures are now believed to be fossilized communities of bacteria and algae — some with remarkably preserved cells and organic material still intact
Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs。 By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice。 They then used a gene therapy inspired by zebrafis
