MIT researchers were able to reverse depression-like behavior by reactivating happy memories, writes Carolyn Gregorie for The Huffington Post. Graduate student and lead author Steve Ramirez “hopes that scientists will one day find a way to prevent depressive symptoms from occurring in the first place.”
In this video, CNN examines a new printable origami robot developed by MIT researchers that can dissolve in a variety of liquids. CNN explains that the researchers hope that the robot could one day be used to perform medical tasks inside the human body.
Professor Susumu Tonegawa’s research group has found that artificially stimulating positive memories can ease depression, reports Jonathan Webb for BBC News. Webb explains that the research “demonstrates the power of rekindling happy memories.”
In an article for The Wall Street Journal, Chris Jacobs writes about a study co-authored by Prof. Amy Finkelstein that examines the utility and efficiency of Medicaid coverage. The study “found that beneficiaries valued Medicaid at 20 cents to 40 cents on the dollar,” writes Jacobs.
In an article for TIME, Jeffrey Kluger reports that MIT researchers have uncovered the mystery behind Saturn’s Earth-sized cyclones. The researchers found that lots of mini-storms combine to produce “one massive, long-lived one at the top of the planet.”
MIT physicists have cooled molecules to just above absolute zero, reports Macrina Cooper-White for The Huffington Post. “The team hopes to cool molecules to an even lower temperature, study the interactions between them, and learn more about the limits on their lifetime,” Cooper-White explains.
Graduate student Tristan Swedish has devised a concept for a device that allows patients to photograph their retinas, according to The Economist. Swedish hopes the device could allow, “people to monitor themselves and, if there are any warning signs, to be advised to see a doctor.”
Jesse Emspak of Live Science writes that MIT researchers have successfully cooled molecules to just above absolute zero. The researchers found that when the molecules were cooled to 500 nanokelvins they “were quite stable, and tended not to react with other molecules around them.”
New Scientist reporter Rowan Hooper writes about how MIT researchers have developed a 1.7-centimeter long origami robot that can self-fold, walk and swim. Hooper explains that, “using liquid-soluble materials, different versions of the robot can dissolve in either water or acetone, leaving only the permanent magnet behind.”
Financial Times reporter Eric Beinhocker reviews Prof. César Hidalgo’s new book, “Why Information Grows: The Evolution of Order, from Atoms to Economies.” Beinhocker writes that Hidalgo’s book is, “the future of growth theory and his thought-provoking book deserves to be widely read.”
MIT researchers have developed lightweight, inflatable tents that could allow astronauts to spend more time exploring the moon, reports Charles Choi for Popular Science. Choi explains that the “mobile overnight habitat, designed to fit aboard a no-frills lunar rover” would only take up “roughly half as much space as an average refrigerator” when packed.
Prof. Ki Goosens is investigating how the gherlin hormone could possibly be used to develop a vaccine for PTSD, reports Bree Sison for CBS Boston. “If we can pick even just one mental illness and improve the outcome for people who suffer from it, I’d be happy,” says Goosens.
MarketWatch reporter Sally French writes that researchers from MIT CSAIL have developed an algorithm that can be used to predict how memorable a person’s is. “The algorithm was created from a database of more than 2,000 images that were awarded a “memorability score” based on human volunteers’ ability to remember the pictures,” French writes.
In an article for Nautilus, Elizabeth Preston writes about Prof. Lydia Bourouiba’s work examining how rain can spread crop diseases. Through a close examination of high-speed images, Bourouiba found that how raindrops bounce off different plant leaves “is really at the root” of the spread of pathogens among plants.
A new study co-authored by MIT Prof. Joseph Doyle found that juveniles who were incarcerated were less likely to return to school and more likely to return to jail as adults, reports Chris Sweeney for Boston Magazine. “If you want to be tough on crime, locking up juvenile offenders is counterproductive,” says Doyle.
