A team of engineers at the University of California San Diego has developed the first fully integrated wearable ultrasound system for deep-tissue monitoring, including for subjects on the go. It facilitates potentially life-saving cardiovascular monitoring and marks a major breakthrough for one of the world’s leading wearable ultrasound labs. The paper, “A fully integrated wearable ultrasound system to monitor deep tissues in moving subjects,” is published in the May 22, 2023 issue of Nature Biotechnology.

“This project gives a complete solution to wearable ultrasound technology — not only the wearable sensor, but also th...

Scientists make First Observation of a Polar Cyclone on Uranus

NASA scientists used microwave observations to spot the first polar cyclone on Uranus, seen here as a light-colored dot to the right of center in each image of the planet. The images use wavelength bands K, Ka, and Q, from left. To highlight cyclone features, a different color map was used for each.

Scientists used ground-based telescopes to get unprecedented views, thanks to the giant planet’s position in its long orbit around the sun.

For the first time, NASA scientists have strong evidence of a polar cyclone on Uranus. By examining radio waves emitted from the ice giant, they detected the phenomenon at the planet’s north pole...

Using a new strategy, researchers were able to reduce the challenging MRSA infection in the wounds of diabetic mice by 94%. They were able to completely sterilize the wounds in several of the mice, and the rest had significantly reduced bacterial burden.

Chronic wounds are open sores or injured tissue that fail to heal properly. These types of wounds are notoriously challenging to treat because of bacterial infections like Staphylococcus aureus, or S. aureus. Additionally, bacterial infections that are highly resistant to antibiotics, such as methicillin-resistant S...
