New training technique would reveal the basis for machine-learning systems’ decisions by Larry Hardesty, MIT News Office CAMBRIDGE, Mass. — In recent years, the best-performing systems in artificial-intelligence research have come courtesy of neural networks, which look for patterns in training data that yield useful predictions
Imaging technique that creates 3-D video of serotonin transport could aid antidepressant development by Rob Matheson, MIT News CAMBRIDGE, Mass. — Serotonin is a neurotransmitter that’s partly responsible for feelings of happiness and for mood regulation in humans. This makes it a common target for antidepressants,
Brain cells that provide structural support also influence feeding behavior, study shows by Anne Trafton, MIT News CAMBRIDGE, MA – MIT neuroscientists have discovered that brain cells called glial cells play a critical role in controlling appetite and feeding behavior. In a study of mice,
Freeze-dried cellular components can be rehydrated to churn out useful proteins. by Anne Trafton, MIT News Office CAMBRIDGE, MA — Researchers at MIT and other institutions have created tiny freeze-dried pellets that include all of the molecular machinery needed to translate DNA into proteins, which
Newly discovered phenomenon could affect materials in batteries and water-splitting devices by David L. Chandler, MIT News Office CAMBRIDGE, Mass. — When one type of an oxide structure called perovskite is exposed to both water vapor and streams of electrons, it exhibits behavior that researchers
By Jennifer Chu, MIT News Office Rubbery hair-lined wetsuits may help keep surfers warm CAMBRIDGE, Mass. — Beavers and sea otters lack the thick layer of blubber that insulates walruses and whales. And yet these small, semiaquatic mammals can keep warm and even dry while diving,
Technique mass-produces uniform, encapsulated particles for pharmaceuticals, many other uses Larry Hardesty, MIT News Office CAMBRIDGE, Mass. — Microencapsulation, in which a tiny particle of one material is encased within a shell made from another, is widely used in pharmaceuticals manufacturing and holds promise for other
Energy storage device could produce more power than current versions of this technology By David L. Chandler, MIT News Office CAMBRIDGE, Mass. — Energy storage devices called supercapacitors have become a hot area of research, in part because they can be charged rapidly and deliver
Device can predict tumor responses by measuring cell growth after drug exposure Anne Trafton, MIT News Office CAMBRIDGE, MA — Choosing the best treatment for a cancer patient is often an inexact science. Drugs that work well for some patients may not help others, and
Anne Trafton, MIT News Office Researchers at MIT and other institutions have created tiny freeze-dried pellets that include all of the molecular machinery needed to translate DNA into proteins, which could form the basis for on-demand production of drugs and vaccines.
