Medical Xpress / Blood and spinal fluid proteins reveal distinct fingerprints of four brain diseases
Researchers at WashU Medicine have uncovered new molecular insights into Alzheimer's disease, Parkinson's disease and other forms of dementia by analyzing thousands of proteins in both cerebrospinal fluid and blood plasma. ...
Phys.org / Self-regulating process governs cosmic order inside star clusters
A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, the mass of new stars born inside a star cluster is actually governed by a defined process of self-regulation. ...
Phys.org / Chromosomes condense in three timed chemical waves during cell division, study shows
DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes. These histones carry numerous chemical modifications that act as molecular signals, controlling ...
Phys.org / Promising H5N1 vaccine protects dairy calves and mice against severe disease
Researchers at the University of Nebraska–Lincoln have developed a vaccine approach that shows promise in protecting against highly pathogenic bird flu, demonstrating strong efficacy in both mice and cattle. Avian influenza ...
Phys.org / Sombrero Galaxy's vast halo emerges in rare detail 30 million light-years away
Messier 104, nicknamed the Sombrero Galaxy, is a popular target for amateur observing and astronomical research. Its recognizable extended halo, as well as a faint stellar stream, are captured in exquisite detail in this ...
Phys.org / A mother's gift: Plastid-derived structures help sea urchin development and dispersal
During the development of marine organisms—from fertilization through to juvenile stages—it is often observed that the eggs released into the water column are initially supplied with only a small fraction of the energy they ...
Medical Xpress / Label-free optical imaging enables automated measurement of human white matter microstructure
White matter pathways allow distant parts of the brain to communicate, supporting memory, emotion, and language. One such pathway, the uncinate fasciculus, connects the front of the temporal lobe with regions of the frontal ...
Phys.org / Low wages, poor training put security guards—and the public—at risk, study finds
Tens of thousands of private security guards in California play a critical role in public safety, but poverty-level wages and poor training put both the guards and the public at risk, according to a new study by the UC Berkeley ...
Medical Xpress / New study finds high rates of outpatient antibiotic exposure in children with medical complexity
A new study from Boston Children's Hospital found that annual prescription rates increased nonlinearly as children's underlying level of medical complexity increased. Frequent antibiotic use has associated risks, including ...
Phys.org / One blue whale song unlocks oceans of data
Trying to find a whale song in the ocean is like trying to find a needle in a haystack. But now, UNSW Sydney researchers say they've trained a model, with just a single case study, to find blue whale songs in recordings that ...
Phys.org / Genomic tool untangles how microbes spread—even when they look almost identical
Researchers have developed a powerful new tool that can track how microbes spread between people with unprecedented precision, offering new ways to prevent infections and improve treatments in the future. The research, published ...
Phys.org / Extra sets of chromosomes may help aggressive tumor cells spread, study finds
One of the biggest challenges in cancer research is understanding why some tumor cells become especially aggressive, invasive and resistant to treatment. Scientists have increasingly linked these dangerous traits to polyploid ...
