University of Queensland researchers have developed new noninvasive sensors that measure muscle forces, unlocking new possibilities for wearable robotic mobility devices. Ultra-wideband radar sensors measure electromagnetic ...

In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult ...

One year after unveiling a first-of-its-kind "microwave brain" microchip capable of computing on ultrafast data and wireless signals, researchers from the Cornell Duffield College of Engineering have shown how the chip can ...

Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat. Many eventually undergo surgery under general anesthesia, while others endure pain ...

Since their discovery by NASA's James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has ...

Researchers have developed and tested an infrared spectroscopy system that can rapidly detect chemical aerosols from a distance by using light reflected from common surfaces such as traffic signs, tree trunks or painted surfaces. ...

A team of researchers has discovered that winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery ...

Remembering the past can help living organisms make better decisions, but memory comes at a cost. Whether it is an animal searching for food or a single cell responding to its surroundings, storing and using information requires ...

A newly discovered dinosaur from Zimbabwe is offering fresh clues to how the animals diversified, suggesting they spread across distinct ecosystems in southern Africa, scientists said Wednesday.

When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it can do any harm. Biology ...

Despite the promise of rebounding green sea turtle numbers, many sea turtle populations continue to flounder under the pressures of changing climates, overfishing and urbanization.

Using neutrons at the Department of Energy's Oak Ridge National Laboratory, researchers from The Ohio State University are studying residual stress caused by friction stir welding (FSW) to reveal how to strengthen armor steel ...
