Medical Xpress / Research reveals how blood flow directs vessel health at the molecular level
How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi University and the InFLAMES ...
Medical Xpress / Lost under stress? Study shows cortisol can scramble the brain's internal map
The stress hormone cortisol disrupts the brain's navigational system. It impairs the function of the grid cells that play a crucial role in orientation. This has been verified by researchers from Ruhr University Bochum, Germany, ...
Phys.org / Ultrasound-based approach to delivering potent drugs into cancer cells shows promise in benchtop experiments
Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct. Dubbed "Sonoporation-assisted Precise ...
Phys.org / Geospatial model maps potential lumpy skin disease entry points into Australia
Two locations have been identified as the most likely entry points into Australia for a disease that poses a huge risk to the beef and dairy industries. A University of Queensland-led team has built the first geospatial model ...
Phys.org / How an unlikely all-female clonal fish species copied and pasted itself free from extinction
The tiny Amazon molly (Poecilia formosa) has always fascinated researchers because, according to the rules of evolution, it shouldn't have survived as a species, let alone thrive as a species for over 100,000 years. Using ...
Tech Xplore / New chip lets robots see in 4D by tracking distance and speed simultaneously
Current vision systems for robots and drones rely on 3D sensors that, although powerful, do not always keep up with the fast-paced, unpredictable movement of the real world. These systems often struggle to measure speed instantly ...
Phys.org / Urban park soil microbes reveal function–evolution trade-off
Urban parks are a vital component of urban ecosystems and provide distinctive habitats for soil microorganisms. Yet scientists have questioned whether—and how—the functional diversity and evolutionary potential of microbial ...
Phys.org / Leopard gecko study clarifies how temperature shapes sex development
In reptiles, a simple temperature change can determine whether an egg develops into a male or female. This process is formally known as temperature-dependent sex determination (TSD), in which the sex of an embryo is determined ...
Medical Xpress / Experimental Alzheimer's drug reverses memory loss in mice by reprogramming gene activity
A team from the University of Barcelona has designed and validated in animal models an innovative compound with a pioneering mechanism of action for the treatment of Alzheimer's disease. Unlike current drugs, which mainly ...
Phys.org / Quantum computers must overcome major technical hurdles before tackling quantum chemistry problems
Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, published in Physical ...
Medical Xpress / How the brain filters out 'expected' sounds: Orbitofrontal cortex study offers new insight
Humans and other animals gradually learn what sounds or other sensory cues in their surroundings are meaningful or potentially threatening. Via a process known as habituation, they gradually learn to ignore non-threatening ...
Medical Xpress / Machine learning models identify key predictors of driving under the influence of alcohol or cannabis
The frequency of substance use, early age of initiation, and cannabis-related memory impairments are among the primary factors contributing to driving under the influence, according to a new analysis using machine learning. ...
