Philosophers have debated the nature of “nothing” for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, explains that when physicists talk about nothing, they mean empty space (vacuum). […]

In their paper published in Proceedings […]
Pills hailed as the first real “anti-aging” drugs inched a little closer to the market after a study found they cut the number of respiratory infections in the elderly by half. The drugs: The pills act on an aging-related pathway called TORC1. Inhibiting this pathway “has extended life span in every species studies to date,” […]
As if the line between human and machine wasn’t already blurry enough, researchers in Tokyo have developed a new method for using living rat muscle tissue in robotics. The “biohybrid” design, described today in the journal Science Robotics, simulates the look and movements of a human finger. Video shows how it bends at the joint, […]
Viruses attached to a fragment of a bacterial cell wall. “Viruses modulate the function and evolution of all living things,” scientists wrote last year. “But to what extent remains a mystery.”
Researchers have found hundreds of years’ worth of rare-earth materials underneath Japanese waters — enough to supply to the world on a “semi-infinite basis,” according to a study published in Nature Publishing Group’s Scientific Reports. Rare-earth metals are crucial in the making of high-tech products such as electric vehicles and batteries, and most of the […]
“No one thought this was possible in solid materials.” One of the ultimate goals of modern physics is to unlock the power of superconductivity, where electricity flows with zero resistance at room temperature. Progress has been slow, but physicists have just made an unexpected breakthrough. They’ve discovered a superconductor that works in a way no […]
Scientists have developed a new type of “super wood” that is more than 10 times stronger and tougher than normal wood – and this innovation could potentially become a natural and inexpensive substitute for steel and other materials.
The slope rises as high as London’s Big Ben tower. Beneath its ruddy layer of dirt is a sheet of ice 300 feet thick that gives the landscape a blue-black hue. If such a scene sounds otherworldly, it is. To visit it, you’ll have to travel to Mars.
The drug reportedly increases the metabolism of white fat cells.
