Study links intense energy bursts to ventilator-induced lung injury

Matter and energy from Science Daily Feed - Mon, 03/03/2025 - 4:13pm
A new study sheds light on ventilator-induced lung injury, a complication that gained increased attention during the COVID-19 pandemic, which led to a surge in patients requiring mechanical ventilation. The study suggests that repeated collapse and reopening of tiny alveoli -- air sacs in the lungs essential for breathing -- during mechanical ventilation may cause microscopic tissue damage, playing a key role in ventilator-related injuries that contribute to thousands of deaths annually.

From handicap to asset: AI approach leverages optics phenomenon to produce better images

Matter and energy from Science Daily Feed - Mon, 03/03/2025 - 11:20am
Quantitative phase imaging (QPI) is a microscopy technique widely used to investigate cells and tissues. Even though first biomedical applications based on QPI have been developed, both acquisition speed and image quality need to improve to guarantee a widespread reception. Scientists suggest leveraging an optical phenomenon called chromatic aberration -- that usually degrades image quality -- to produce suitable images with standard microscopes.

ChatGPT on the couch? How to calm a stressed-out AI

Computers and Math from Science Daily Feed - Mon, 03/03/2025 - 11:16am
Distressing news and traumatic stories can cause stress and anxiety -- not only in humans, but these stories can also affect AI language models, such as ChatGPT. Researchers have now shown that these models, like humans, respond to therapy: an elevated 'anxiety level' in GPT-4 can be 'calmed down' using mindfulness-based relaxation techniques.

A hot droplet can bounce across a cool pan, too

Matter and energy from Science Daily Feed - Mon, 03/03/2025 - 11:12am
When a droplet of water falls on a hot pan, it dances across the surface, skimming on a thin layer of steam like a tiny hovercraft; this is known as the Leidenfrost effect. But now, researchers know what happens when a hot droplet falls on a cool surface. These new findings demonstrate that hot and burning droplets can bounce off cool surfaces, propelled by a thin layer of air that forms beneath them. This phenomenon could inspire new strategies for slowing the spread of fires and improving engine efficiency.
