New Formula Leads to Improved Liquid Battery

MIT engineers have developed an improved liquid battery system that could enable renewable energy sources to compete with conventional power plants. Extensive testing has shown that even after 10 years of daily charging and discharging, the system should retain about 85 percent of its initial efficiency. Donald Sadoway and colleagues have already started a company […]

New Materials Have the Ability to Quickly Change Colors and Textures

A team of engineers has developed a new synthetic material that can change its fluorescence and texture in response to a change in voltage applied to it. Cephalopods, which include octopuses, squid, and cuttlefish, are among nature’s most skillful camouflage artists, able to change both the color and texture of their skin within seconds to […]

Sun Powered Desalination technology To Provide Drinking Water for India

A newly published study from MIT shows that a desalination technology powered by solar panels could provide enough clean drinking water for many of the typical villages in India. Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water — and much […]

Neuroscientists Reverse Emotional Association of Memories

Neuroscientists from MIT have identified the brain circuit that controls how memories become linked with positive or negative emotions, revealing that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics. Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach […]

Coated Tissue Scaffolds Help the Body Grow New Bone

Chemical engineers from MIT have developed coated tissue scaffolds that help the body grow new bone to repair injuries or congenital defects. MIT chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold […]

New Evidence Raises Questions About When Dinosaurs Evolved in North America

Scientists at MIT precisely dated the rocks in which the earliest dinosaur fossils were discovered in the southwestern United States, raising questions about when dinosaurs evolved in North America. The Jurassic and Cretaceous periods were the golden age of dinosaurs, during which the prehistoric giants roamed the Earth for nearly 135 million years. Paleontologists have […]
