Phys.org / Phages unlock essential vitamin B12 by bursting open gut bacteria
All living organisms need vitamin B12 to form red blood cells and DNA, as well as to build and support brain and nerve cells. But it's hard to come by: Humans don't make it. Animals don't make it. Plants don't make it. In ...
Medical Xpress / Household hums below hearing range damage mouse kidneys in five-day experiment
Previous studies have hinted that people surrounded by more environmental noise—low, deep rumblings from air-conditioning units, elevator motors, distant traffic and ventilation ducts—tend to have worse kidney function. But ...
Phys.org / Birdsong and whale song show patterns similar to human language
An international team of researchers has uncovered a previously undetected structure in the birdsong of Bengalese finches that has the same statistical patterns found in human languages.
Medical Xpress / A precise neuronal mechanism allows the brain to plan future routes to remembered goals
When humans and other animals move through familiar or unfamiliar environments, their brains rely on numerous intricate neural processes to decide which path to take next. Past studies have identified a specific population ...
Phys.org / JWST study suggests a handful of 'leaky' galaxies reionized the early universe
A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work ...
Medical Xpress / Brain activity reveals two stages of visual processing before conscious perception
Seeing feels immediate; we open our eyes and the world seems to appear as a continuous stream. But some visual illusions show that events occurring later can change how we perceive what happened earlier, suggesting that the ...
Phys.org / First full zoysia grass genetic blueprint opens doors for drought-tolerant turf
A new genomic resource from the Texas A&M AgriLife Research plant genomics team is providing a powerful new foundation for faster, more precise turfgrass genetics and breeding. The team discovered a breakthrough genome that ...
Medical Xpress / Parkinson's-linked α-synuclein blocks protein transport in neurons, disrupting cells' waste recycling
Parkinson's disease affects more than 10 million people worldwide. The disease is characterized by the buildup of abnormal clumps of the protein alpha-synuclein inside brain cells, but scientists have long struggled to understand ...
Phys.org / Sunlight-powered setup generates quantum entanglement
Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that quantum entanglement between photons ...
Phys.org / Antenna-like cell appendage may help turtle embryos sense sex-deciding nest temperatures
When most baby turtles hatch, their sex depends on the temperature of the sand or soil where their mother laid her eggs. Warm incubation produces females, while cool nests produce males.
Phys.org / Hydraulic traits reveal why some mountain trees move uphill while others shift downhill
As global temperatures rise, scientists have largely assumed that mountain tree species will move uphill in search of cooler conditions. A new study published in Nature Climate Change reveals a more complex reality: Some ...
Medical Xpress / Common midlife vascular risk factors may cut dementia-free life by up to 13 years
A new study, published in Neurology Open Access, shows an association between three common vascular risk factors and the amount of dementia-free time people experience after age 55. The study hints that dementia is not inevitable ...
