A Yale-led research team has discovered a galaxy that contains no dark matter — a finding that confirms the possibility of dark matter as a separate material elsewhere in the universe. The discovery has broad implications for astrophysics, the researchers said. It shows for the first time that dark matter is not always associated with […]

Ever heard of the planet Vulcan? In the late 1800s, many scientists thought it was real: a hot planet near Mercury (thus named for the god of the forge), whose gravitational pull supposedly caused a wobble in Mercury’s orbit. But in 1915, Albert Einstein killed off this notion, as MIT’s Thomas Levenson recounts in his […]

Research Triangle engineers have developed a simple, energy-efficient way to create three-dimensional acoustic holograms. The technique could revolutionize applications ranging from home stereo systems to medical ultrasound devices. Most everyone is familiar with the concept of visual holograms, which manipulate light to make it appear as though a 3-D object is sitting in empty space. […]

Early detection of the most common form of epilepsy in children is possible through “deep learning,” a new machine learning tool that teaches computers to learn by example, according to a new study that includes researchers from Georgia State University. Benign epilepsy with centrotemporal spikes (BECT), one of the most frequent epilepsies, accounts for 15 […]

As an embryo develops, tissues bend into complex three-dimensional shapes that lead to organs. Epithelial cells are the building blocks of this process forming, for example, the outer layer of skin. They also line the blood vessels and organs of all animals. These cells pack together tightly. To accommodate the curving that occurs during embryonic […]

Multiferroics – materials that exhibit both magnetic and electric order – are of interest for next-generation computing but difficult to create because the conditions conducive to each of those states are usually mutually exclusive. And in most multiferroics found to date, their respective properties emerge only at extremely low temperatures. Two years ago, researchers in […]
