New Type of Electrolyte Could Enhance Supercapacitor Performance

Novel class of “ionic liquids” may store more energy than conventional electrolytes — with less risk of catching fire. Supercapacitors, electrical devices that store and release energy, need a layer of electrolyte — an electrically conductive material that can be solid, liquid, or somewhere in between. Now, researchers at MIT and several other institutions have developed a […]

Evidence Shows Dinosaur Extinction Drove Pulses of Fish Diversification

A research team has found new evidence that fish rapidly evolved in two phases following the Cretaceous-Paleogene (K/Pg) mass extinction that occurred 66 million years ago. The team, which included Yale’s Pincelli Hull, made the discovery by examining microscopic fish teeth preserved in sediments buried deep in the bottom of the Pacific Ocean. Elizabeth Sibert […]

Mass Extinction Happened in a Geological ‘Instant’

It took less than 30,000 years and maybe only thousands, to kill more than 90% of sea creatures and most land species, according to the most precise study ever published about the mass extinction marking the end of the Permian Period. Earth’s greatest mass extinction, also known as the “Great Dying,” occurred about 252 million […]

Easter Island’s Moai Provide Hints of a Complex Society

You probably know Easter Island as “the place with the giant stone heads.” This remote island 2,300 miles off the coast of Chile has long been seen as mysterious—a place where Polynesian seafarers set up camp, built giant statues, and then destroyed their own society through in-fighting and over-exploitation of natural resources. However, a new […]

Probiotics and Antibiotics Eradicate Drug-Resistant Bacteria

In the fight against drug-resistant bacteria, MIT researchers have enlisted the help of beneficial bacteria known as probiotics. In a new study, the researchers showed that by delivering a combination of antibiotic drugs and probiotics, they could eradicate two strains of drug-resistant bacteria that often infect wounds. To achieve this, they encapsulated the probiotic bacteria in a […]

Scientists Develop a New Way to Turn Sunlight Into Fuel

The quest to find new ways to harness solar power has taken a step forward after researchers successfully split water into hydrogen and oxygen by altering the photosynthetic machinery in plants. Photosynthesis is the process plants use to convert sunlight into energy. Oxygen is produced as by-product of photosynthesis when the water absorbed by plants […]

Scientists Use Acoustic Forces to Print Like Never Before

Honey is a prototypical example for viscous fluid, being 25 thousand times more viscous than water. Acoustophoretic printing enables droplet formation of any material, generating the tiniest possible single drop of honey in a tiny honey jar. Credit: Daniele Foresti, Jennifer A. Lewis/Harvard University Harvard University researchers have developed a new printing method that uses […]
