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 / 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 / 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 ...
