Can this Thumb Test tell if you are at increased Risk of a Hidden Aortic Aneurysm?

All the parts of our bodies share an inherent connectivity. This goes much further than “the foot bone’s connected to the … leg bone.” For instance, both hands and feet are connected to a constantly flowing bloodstream, and a nerve network that makes their muscles kick.

So what about the connection recently proposed by some news outlets regarding a simple test involving your palm and thumb? Could it really help diagnose a silent, yet potentially serious problem?

An aneurysm is what we’re referring to here. This is a ballooned segment of an artery—the vessels that supply oxygenated blood to your body tissues. Aneurysms may cause no problems, but if they grow larger, they can weaken, burst and bleed...

Stretchable E-Skin could give Robots Human-Level Touch Sensitivity

A first-ever stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.

The new stretchable e-skin, developed by researchers at The University of Texas at Austin, solves a major bottleneck in the emerging technology. Existing e-skin technology loses sensing accuracy as the material stretches, but that is not the case with this new version.

“Much like human skin has to stretch and bend to accommodate our movements, so too does e-skin,” said Nanshu Lu, a professor in the Cockrell School of Engineering’s Department of Aerospace Engineering and Engineering Mechanics wh...

New Discoveries about Jupiter’s Magnetosphere

New discoveries about Jupiter could lead to a better understanding of Earth’s own space environment and influence a long-running scientific debate about the solar system’s largest planet.
“By exploring a larger space such as Jupiter, we can better understand the fundamental physics governing Earth’s magnetosphere and thereby improve our space weather forecasting,” said Peter Delamere, a professor at the UAF Geophysical Institute and the UAF College of Natural Science and Mathematics.

“We are one big space weather event from losing communication satellites, our power grid assets, or both,” he said.

Space weather refers to disturbances in the Earth’s magnetosphere caused by interactions between the solar wind and the Earth’s magnetic field...

A Common Type of Fiber may Trigger Bowel Inflammation

Inulin, a type of fiber found in certain plant-based foods and fiber supplements, causes inflammation in the gut and exacerbates inflammatory bowel disease in a preclinical model, according to a new study by Weill Cornell Medicine investigators. The surprising findings could pave the way for therapeutic diets that may help ease symptoms and promote gut health.

The study, published March 20 in the Journal of Experimental Medicine, shows that inulin, which is found in foods such as garlic, leeks and sunchoke, as well as commonly used fiber supplements and foods with added fiber, stimulates microbes in the gut to release bile acids that increase the...
