Scientists at the Swiss Light Source SLS have succeeded in mapping a piece of brain tissue in 3D at unprecedented resolution using X-rays, non-destructively. The breakthrough overcomes a long-standing technological barrier that had limited the use of X-rays for such studies. With the SLS upgrade now complete, the path lies open to imaging much [...]
Researchers found persistent microclot and NET structures in Long COVID blood that may explain long-lasting symptoms. Researchers examining Long COVID have identified a structural connection between circulating microclots and neutrophil extracellular traps (NETs). The discovery indicates that the two may interact in the body in ways that could lead to harmful effects when these [...]
Groups of normal cbiells can sense far into their surroundings, helping explain cancer cell migration. Understanding this ability could lead to new ways to limit tumor spread. The tale of the princess and the pea describes someone so sensitive that she can detect a single pea beneath layers of bedding. In the biological world, [...]
Bacteria that multiply on surfaces are a major headache in health care when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon to fight these hotbeds of bacterial growth—one that does not rely on antibiotics or toxic metals. The [...]
New research reveals that standard screening misses most people with a common inherited cholesterol disorder. A Mayo Clinic study reports that current genetic screening guidelines overlook most people who have familial hypercholesterolemia, an inherited disorder that can lead to dangerously high cholesterol and early heart disease. This condition can move quietly through families for many years. [...]
Summary: Researchers at Ruhr University Bochum explore why consciousness evolved and why different species developed it in distinct ways. By comparing humans with birds, they show that complex awareness may arise through different neural architectures yet serve similar purposes. New research examines why consciousness evolved by comparing humans with birds. What evolutionary purpose does consciousness serve, [...]
Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have reported early success with a novel mRNA-based therapy designed to combat antibiotic-resistant bacteria. The findings, published in Nature Biotechnology, show that in preclinical studies in mice and human lung tissue in the lab, the therapy slowed bacterial growth, strengthened immune cell activity, [...]
A breakthrough zwitterionic polymer slips through the skin’s toughest barriers, carrying insulin deep into tissue and normalizing blood sugar, offering patients a painless alternative to daily injections. A recent study published in the journal Nature examines the use of the skin-permeable molecule poly[2-(N-oxide-N,N-dimethylamino)ethyl methacrylate] (OP) as a delivery system for insulin, a key drug in the [...]
Antibiotic resistance is a growing concern - from human health to crop survival. A new study successfully uses nanogels to target and almost entirely inhibit the bacteria P. Aeruginosa. Recently published in Angewandte Chemie, the study demonstrates 99.9 % effective inhibition against P. Aeruginosa, a particularly evasive bacterium. By combining pathogen-specific sugar ligands with a membrane-disrupting antimicrobial peptide, [...]
Biomedical researchers at Texas A&M University may have discovered a way to stop or even reverse the decline of cellular energy production—a finding that could have revolutionary effects across medicine. Dr. Akhilesh K. Gaharwar and Ph.D. student John Soukar, along with their fellow researchers from the Department of Biomedical Engineering, have developed a new [...]
