Phys.org / Atomic view of Alzheimer's disease peptide could inform new drugs
One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide ...
Phys.org / AI and 'Ramanomics' could eliminate a major obstacle to studying living cells
Fluorescent dyes have long been used in biological research to identify and visualize structures within living cells. Although effective, they have several drawbacks, including altering the cells under study, limiting the ...
Medical Xpress / How multinucleated cells help the brain reorganize after localized astrocyte loss
The human brain contains various types of cells that collectively support its functions. In addition to neurons, nerve cells that communicate via electrical and chemical signals, it also relies on star-shaped cells known ...
Phys.org / Backpack lab finds wastewater contamination and drug-resistant bacteria in Galápagos waters
From routine surgeries to cancer treatment, modern medicine depends on drugs that can fight infections caused by microbes such as bacteria, viruses, fungi and parasites. But some microbes are becoming resistant to the drugs ...
Medical Xpress / Scientists discover a brain cycle that may explain why learning eventually stalls
For many who have struggled to learn a new language or instrument, it's a familiar pattern: They make rapid progress at first, then hit a plateau that no amount of diligent practice or concentration seems to break.
Phys.org / Bioengineers develop biochemical halo to cloak insulin-producing cells from body defenses
A protein known as interleukin 10 (IL-10) is the lynchpin of a new method to protect transplanted cells from host immune system attacks. Rice University researchers engineered a living factory to produce a localized biochemical ...
Phys.org / Fossils from Wyoming's Smiley Draw deepen understanding of early primate evolution
A new study from the University of Kansas complicates the picture of primates living in North America some 55 million years ago during the Eocene, a warm period that allowed mammals to diversify quickly.
Phys.org / 'Little red dots' may be pulsating monster stars that created early-universe black holes
Astronomers have speculated about the mysterious "little red dots" seen through the James Webb Space Telescope's images of the early universe: They could be galaxies, black holes, quasi-stars, starbursts ... or something ...
Phys.org / One of the world's only two complete dodo skulls reveals new clues about the extinct bird
Only two complete dodo skulls are known to exist anywhere in the world: one at the Natural History Museum Denmark and one at the Oxford University Museum of Natural History. The specimen housed in Copenhagen has been preserved ...
Phys.org / Turning one of the world's most difficult plastics into premium lubricant
Virginia Tech chemist and chemical engineer Guoliang "Greg" Liu and his lab have developed a process that converts the plastic polyvinyl chloride (PVC) into polyalphaolefin, a key component in lubricants such as engine oil. ...
Phys.org / How the 'fecal revolution' changed Earth's ecosystems
An international study led by Flinders University has found a fertile area of inspiration to explain an important step in evolution—and it's a whole lot of poop. The new study describes the "fecal revolution" to explain a ...
Medical Xpress / What's in kratom products? Tests find 85% conflict with labels
What's listed on a kratom product label may not tell the full story. Researchers in the University of Florida College of Pharmacy have found that commercially available kratom products, including many kratom-derived products, ...
