Medical Xpress / Lab-grown retinal cells show promise for new eye therapies
Biomedical engineers at Duke University have used induced pluripotent stem cells (iPSCs) to grow specialized blood vessel cells critical to retinal health for the first time. When injected into mouse models of retinal disease, ...
Phys.org / Giant exoplanet may hold a magnetic grip on its host star
Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.
Phys.org / How boundary geometry helps embryonic cells organize themselves
One of the most striking biological transitions in nature happens early in development, when an embryo transforms from a simple ball of cells into a highly ordered structure with distinct tissue layers that later develop ...
Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Medical Xpress / New T‑cell therapy targets three tumor proteins, shows early survival gains in aggressive pediatric brain cancers
Researchers report encouraging early results from a first-in-human clinical trial led by Children's National Hospital using a new T-cell immunotherapy for children and young adults with some of the deadliest brain tumors, ...
Phys.org / Unexpected pathway turns water and CO₂ into climate‑neutral methane on nickel–zirconia
Natural gas still plays an important role in many industrial sectors, but it is a climate-damaging fossil fuel. TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible ...
Science X / Built-in 'antenna' may help cells sense a healing spark to guide repair after injury
When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current ...
Medical Xpress / Popular GLP-1 weight loss drugs are being misused by people struggling with eating disorders, research reveals
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as Ozempic or Wegovy, have revolutionized type 2 diabetes and weight-loss management, but they have also led to some unfortunate outcomes. A recent study in JAMA ...
Phys.org / Mummified dogs reveal Tiwanaku people buried companions beside homes long before they became status symbols
In the arid landscapes of southern Peru, around 1,100 years ago, someone carefully dug a small pit, laid down a woven mat and placed a young dog within as if sleeping, possibly wrapped in twine. Centuries later, the mummified ...
Phys.org / Shining blue light on gold-graphene nanodots achieves wound healing trifecta
Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, ...
Phys.org / How cricket mothers control the developmental timing of their offspring
Diapause is a fascinating form of biological dormancy employed by a broad array of animals as a survival strategy to endure adverse environmental conditions. To overcome the problems associated with seasons that are unsuitable ...
Phys.org / Lost megalodon vertebrae resurface, confirming 80-foot size estimate
An associated set of gigantic vertebrae belonging to the iconic extinct megalodon, or megatooth shark, that had been missing in action since the 1980s was discovered, providing new information about the shark's lifestyle. ...
