Tech Xplore / Stacked ionic cells inspired by electric rays generate over 100V for small electronics
Inspired by electric rays that generate high voltages through stacked electrocytes, researchers at UNIST have developed a novel energy harvesting technology that mimics this biological mechanism. Unlike electric rays, which ...
Medical Xpress / Cancer tumors may protect against Alzheimer's by cleaning out protein clumps
Cancer and Alzheimer's are two of the most common chronic diseases associated with aging. For years, doctors have known about a curious aspect of these two conditions: people who survive cancers are significantly less likely ...
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 ...
Medical Xpress / These two viruses may become the next public health threats, scientists say
Two emerging pathogens with animal origins—influenza D virus and canine coronavirus—have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among ...
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 / Chip-sized optical amplifier can intensify light 100-fold with minimal energy
Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to fiber-optic cables that carry the internet across oceans. Stanford physicists recently found a way to make ...
Medical Xpress / Vaping zebrafish suggest e-cigarette exposure disrupts gut microbial networks and neurobehavior
Electronic cigarettes (e-cigarettes), widely marketed as a safer alternative to traditional cigarettes, are now hooking younger generations. World Health Organization data from 2025 show that at least 15 million adolescents ...
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 / 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 / NASA's Juno measures thickness of Europa's ice shell
Data from NASA's Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter's moon Europa. Using the spacecraft's Microwave Radiometer (MWR), mission scientists determined ...
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 / Shipping regulations to reduce pollution may have exacerbated Great Barrier Reef bleaching
Rising ocean temperatures have been implicated in mass coral bleaching events affecting the Great Barrier Reef (GBR). These events have been increasingly frequent, with major events occurring in 2016, 2017, 2020, 2022, 2024, ...
