A research team led by scientists at Queen Mary University of London, UK, has developed a new way to grow materials which could regenerate hard tissues. The materials exhibit high stiffness, hardness, and acid resistance, and could be used for a wide variety of dental complications such as the prevention …

Ever since NASA’s Voyager 1 flew past Jupiter in 1979, planetary researchers have wondered about the origin of Jovian lightning. That encounter confirmed the existence of the lightning, which had been theorized for years. But when the venerable explorer hurtled by, the data showed that the lightning-associated radio signals didn’t …

NASA’s Juno probe has been studying Jupiter for almost two years, but the mission has not gone exactly to plan. It’s taking Juno longer than NASA expected to map the gas giant, and operations were scheduled to cease this summer. Luckily, NASA has secured an additional $1 billion in funding …

A bit more than two years ago, a pair of astronomers made waves when they suggested that the orbits of a group of trans-Neptunian Objects, or TNOs, might be evidence for the existence of an undiscovered planet in our own solar system. This hypothesized world, dubbed Planet 9, would be …

Walking at average or brisk/fast pace is associated with a reduced risk of all-cause and cardiovascular disease (CVD) mortality, an analysis of data from 50,225 walkers has found. Increasing walking pace could reduce risk for all-cause and CVD mortality. Image credit: Daniel Reche. “A fast pace is generally 3-4 mph …

Cells enter a state of dormancy as tissues starved of oxygen become increasingly acidic, according to a new study. Published in the journal Cell, the study found that this dormancy, thought to be a major cause of drug resistance and disease relapses in cancer, might be relatively easy to reverse …

A 6-foot (2 m) wide asteroid called 2018 LA disintegrated harmlessly over Botswana, Africa, just hours after its discovery on Saturday morning (June 2, 2018). Artist’s concept of a near-Earth asteroid. Image credit: NASA / JPL-Caltech. 2018 LA was first discovered by the NASA-funded Catalina Sky Survey, located near Tucson …

Technology is constantly becoming more powerful and compact. What used to require a room full of equipment can now work with devices that fit in the palm of your hand. The same is true of medical devices, which are increasingly designed to be implanted in the human body. However, powering …

The Cretaceous/Paleogene mass extinction ended the reign of the dinosaurs and wiped out 76% of species on Earth. It was caused by the impact of an asteroid in the southern Gulf of Mexico approximately 66 million years ago, forming the Chicxulub impact crater. Although the asteroid killed off species, new …

A new study using X-ray data from NASA’s Chandra X-ray Observatory indicates that the neutron star merger that became the gravitational wave source, GW170817, likely created the lowest mass black hole known. The first artist’s illustration shows a key part of the process that created this new black hole, as …
