New York, Aug 12, 2025.- The skin has two types of adult stem cells: epidermal and hair follicle. Their jobs seem pretty well-defined: maintain the skin, or maintain hair growth. But as research from Rockefeller University has shown, hair follicle stem cells (HFSCs) can switch teams, pitching in to healContinuar Leyendo
In a Q&A, Yale neuroscientist Amy Arnsten discusses the state of Alzheimer’s disease research, exciting treatment breakthroughs on the horizon, and the key role of NIH funding in making it all happen. New Haven, CT, Aug 11, 2025.- One-third of people older than 85 in the United States are estimatedContinuar Leyendo
An international research group involving the University of Bern has discovered that soil microorganisms shift their seasonal rhythm more than plants in response to climate warming. The resulting discrepancy between plants and microorganisms could disrupt essential ecosystem processes and jeopardize their functionality. Bern, 05 Aug, 2025.- Most living creatures followContinuar Leyendo
High levels of a hormone found in cells in the gut could underlie many cases of chronic diarrhoea and help explain up to 40% of cases of patients with irritable bowel syndrome with diarrhoea, according to a new study led by scientists at the University of Cambridge. Cambrigde, Aug 01,Continuar Leyendo
Researchers control ring polymer shapes by tuning electric charge What if a complex material could reshape itself in response to a simple chemical signal? A team of physicists from the University of Vienna and the University of Edinburgh has shown that even small changes in pH value and thus inContinuar Leyendo
More than one star contributes to the irregular shape of NGC 6072 París, July 30, 2025.- Webb’s newest look at planetary nebula NGC 6072 in the near- and mid-infrared shows what may appear as a very messy scene resembling splattered paint. However, the unusual, asymmetrical scene hints at more complicatedContinuar Leyendo
Autophagy is essentially the ‘rubbish collection’ of our cells. If there are problems in this process, which is so important for our health, diseases such as Parkinson’s can result. In their latest study, leading cell biologists at the Max Perutz Labs at the University of Vienna investigated mitophagy – aContinuar Leyendo
Scientists have discovered that certain species of microbe found in the human gut can absorb PFAS – the toxic and long-lasting ‘forever chemicals.’ They say boosting these species in our gut microbiome could help protect us from the harmful effects of PFAS. Cambrigde, July 13, 2025.- PFAS have been linked withContinuar Leyendo
To mark its third year of highly productive science, astronomers used the NASA/ESA/CSA James Webb Space Telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region. Paris, July 10, 2025.- Webb’s NIRCam instrument was used to look at this particular area ofContinuar Leyendo
New York, July 09, 2025.- The COVID pandemic illustrated how urgently we need antiviral medications capable of treating coronavirus infections. To aid this effort, researchers quickly homed in on part of SARS-Cov-2’s molecular structure known as the NiRAN domain—an enzyme region essential to viral replication that’s common to many coronaviruses.Continuar Leyendo
