Researchers from the FAMU-FSU College of Engineering have developed a class of breakthrough motion sensors that could herald a near future of ubiquitous, fully integrated and affordable wearable technology...

The super-Earth exoplanet 55 Cancri e, depicted with its star in this artist’s concept, likely has an atmosphere thicker than Earth’s but with ingredients that could be similar to those of Earth’s atmosphere. Credit: NASA/JPL-Caltech

Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides. Based on a 2016 study using data from NASA’s Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness...

The unparalleled liquid strength of cartilage, which is about 80% water, withstands some of the toughest forces on our bodies. Synthetic materials couldn’t match it – until “Kevlartilage” was developed by researchers at the University of Michigan and Jiangnan University. “We know that we consist mostly of water – all life does – and yet our bodies have a lot of structural stability,” said Nicholas Kotov, the Joseph B. and Florence V. Cejka Professor of Engineering at U-M, who led the study. “Understanding cartilage is understanding how life forms can combine properties that are sometimes unthinkable together.”

Scientists at the University of Sussex have disproved the existence of a specific type of axion – an important candidate ‘dark matter’ particle – across a wide range of its possible masses. The data were collected by an international consortium, the Neutron Electric Dipole Moment (nEDM) Collaboration, whose experiment is based at the Paul Scherrer Institut in Switzerland. Data were taken there and, earlier, at the Institut Laue-Langevin in Grenoble. Professor Philip Harris said: “Experts largely agree that a major portion of the mass in the universe consists of ‘dark matter’. Its nature, however, remains completely obscure...
