Medical Xpress / Brain 'hazmat' protein cleans up tau: Could it prevent dementia?
Researchers at UC San Francisco have identified a hazardous waste collector in the brain that disposes of the toxic clumps of tau protein that can lead to dementia. Neurons with more of this garbage collector, technically ...
Phys.org / One single protein, one big decision: How brown algae know when to reproduce
Scientists at the Max Planck Institute for Biology have discovered a remarkably streamlined strategy for developmental control in brown algae. They have shown that a single ARGONAUTE (AGO) protein orchestrates the transition ...
Phys.org / Great white sharks grow a whole new kind of tooth for slicing bone as they age
A great white shark is a masterwork of evolutionary engineering. These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialized for stealth, speed ...
Phys.org / Hearing angry or happy human voices is linked to changes in dogs' balance
In a small study, dogs experienced both stabilization and destabilization of their balance upon hearing angry or happy human voices, but angry voices were linked to the biggest destabilizing effects. Nadja Affenzeller and ...
Phys.org / The pros and cons of pesticides and fertilizers in real-world mandarin orange farms
Researchers led by Yasunori Ichihashi at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan recently examined how different kinds of pesticides and fertilizers affect mandarin oranges across Japan. Their study, ...
Phys.org / Rare fossils reveal 91 new species that survived ancient mass extinction
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday.
Phys.org / Pesticides significantly affect soil life and biodiversity, study finds
Seventy percent of soils in Europe are contaminated with pesticides. A Europe-wide study co-led by researchers of the University of Zurich now shows that their effects on soil life are substantial, as pesticides suppress ...
Phys.org / Novel 'XFELO' laser system produces razor-sharp X-ray light
A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the process, much like happens ...
Medical Xpress / How the brain's 'memory replay' goes wrong in Alzheimer's disease
Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College London (UCL) scientists. The ...
Phys.org / Surprising green ice on Lake Lipno: Cyanobacteria bloom in mid-winter
An unusual natural phenomenon appeared on Lake Lipno in South Bohemia, the Czech Republic, at the end of 2025. Large amounts of accumulated cyanobacteria in the water caused the ice to turn green. The phenomenon was thoroughly ...
Medical Xpress / Fruit fly 'Fox' neurons show how brains assign value to food
Why do we sometimes keep eating even when we're full and other times turn down food completely? Why do we crave salty things at certain times, and sweets at other times? The answers, according to new neuroscience research ...
Phys.org / A new look at trends in human deaths due to climate extremes
A new study of climate extremes since 1988 finds that many regions have seen increases in deaths due to floods, storms and extreme temperatures. In human terms, the harm comes not just from deaths, but also from lost labor ...
