New research by Prof. Susumu Tonegawa presents the possibility that depression can be alleviated by recalling happy memories, reports Clive Cookson for The Financial Times. The findings suggest, "new ways to treat depression by manipulating memory neurons.”
Wired reporter James Temperton writes that MIT researchers have created a portable spectrometer that is small enough to fit inside a smartphone. The spectrometer could be used to diagnose diseases, “analyse urine samples, check pulse and oxygen levels and measure environmental pollutants,” Temperton explains.
MIT researchers have developed a quantum-dot spectrometer that is small enough to fit into a smartphone, reports Alexandra Ossola for Popular Science. “Having all that computational power in the palms of their hands could help scientists diagnose of diseases (especially skin conditions), test urine samples, or identify food contaminants,” Ossola writes.
Wall Street Journal reporter Gautim Naik interviews Professor Kerry Emanuel about Pope Francis’ encyclical on climate change. “The Pope more or less gets it right on the science,” said Emanuel. “But what struck me was his linking of environmental degradation to cultural, political and social decline.”
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 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.
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.”
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.
Huffington Post reporter Jacqueline Howard writes about how MIT researchers have uncovered what causes the rapid draining of the meltwater lakes atop Greenland’s ice sheet. Howard explains that, “the finding could help scientists better predict how much meltwater from the ice sheet is contributing to rising sea levels, especially as the climate in the region becomes warmer.”
Professor Vladan Vuletić and his colleagues have successfully developed a new technique for simulating friction between two surfaces at the nanoscale, reports Davide Castelvecchi for Nature. The research “could bring enormous savings by reducing friction between the moving parts of machines,” writes Castelvecchi.
Robert Ferris writes for CNBC that MIT researchers have developed a new technique for creating surfaces that can slide past each other without friction. The researchers hope to use the technique to “build devices that can preserve themselves by being nearly immune to friction.”
Jessica Hamzelou writes for New Scientist that MIT researchers have been able to recover memories using light. The technique could eventually be used to help people with Alzheimer’s or amnesia. Hamzelou writes that Prof. Susumu Tonegawa, hopes to “develop a way to reactivate forgotten memories in people before the brain tissue itself is damaged, as is often the case in dementia.”
Washington Post reporter Chris Mooney writes that MIT researchers have found that giant cracks allow for the rapid draining of lakes on Greenland’s ice sheet. “We know that the ice sheet will continue to increase its contribution to sea level rise over the coming years,” explains lead author Laura Stevens. “The implications of this study show us more of how these processes will play out.”
MIT researchers have uncovered how the meltwater lakes atop Greenland’s ice sheet drain, reports Richard Valdmanis for Reuters. Lead author Laura Stevens explains that the findings will help “predict more accurately how supraglacial lakes will affect ice sheet flow and sea level rise.”
