MIT scientists have solved a decades old mystery by demonstrating impact vaporization is the primary cause of the moon’s thin atmosphere, reports Eric Lagatta for USA Today. The findings, “have implications far beyond determining the moon's atmospheric origins,” writes Lagatta. “In fact, it's not unthinkable that similar processes could potentially be taking place at other celestial bodies in the solar system.”
By analyzing isotopes of potassium and rubidium in the lunar soil, Prof. Nicole Nie and her team have demonstrated that micrometeorite impacts are the main cause of the moon’s thin atmosphere, reports Isabel Swafford for National Geographic. “Understanding the space environments of different planetary bodies is essential for planning future missions and exploring the broader context of space weathering,” says Nie.
Newsweek reporter Jess Thomson spotlights, Prof. Nicole Nie’s research uncovering the origins of the moon’s thin atmosphere. “The researchers described how lunar samples from the Apollo missions revealed that meteorites of varying sizes have constantly hit the moon's surface, vaporizing atoms in the soil and kicking them up into the atmosphere,” writes Thomson. “The constant hitting of the moon replenishes any gases lost to space.”
By analyzing lunar soil samples, MIT scientists have found that the moon’s thin atmosphere was created by meteorite impacts over billions of years, reports Will Dunham for Reuters. “Many important questions about the lunar atmosphere remain unanswered,” explains Prof. Nicole Nie. “We are now able to address some of these questions due to advancements in technology.”
MIT scientists analyzed lunar soil samples and discovered that meteorite impacts likely created the moon’s thin atmosphere, reports Nicola Davis for The Guardian. “Our findings provide a clearer picture of how the moon’s surface and atmosphere interact over long timescales, [and] enhance our understanding of space weathering processes,” explains Prof. Nicole Nie.
MIT scientists have discovered how propofol, a commonly used anesthetic, induces unconsciousness, reports Adam Kovac for Gizmodo. “The new research indicates that [propofol] works by interfering with a brain’s ‘dynamic stability’ – a state where neurons can respond to input, but the brain is able to keep them from getting too excited,” explains Kovac.
MIT scientists have found that lakes and seas made of methane may have shaped Titan’s shores, writes Jess Thomson for Newsweek. “This discovery could allow astronomers to learn even more about the conditions on Titan,” writes Thomson. “Knowing that waves carved out the coast enables them to predict how fast and strong the winds on the moon are and from which direction they blow.”
Gizmodo reporter Passant Rabie spotlights new research by MIT geologists that finds waves of methane on Titan likely eroded and shaped the moon’s coastlines. “If we could stand at the edge of one of Titan’s seas, we might see waves of liquid methane and ethane lapping on the shore and crashing on the coasts during storms,” explains Prof. Taylor Perron. “And they would be capable of eroding the material that the coast is made of.”
Prof. Bob Langer and Prof. Giovanni Traverso have co-founded Syntis Bio, a biotech company that will use technology to “coat the stomach and potentially other organ surfaces, [change] the way that drugs are absorbed or, in the case of obesity, which hormones are triggered,” reports Allison DeAngelis for STAT.
Prof. Anna Frebel joins Arun Rath of WGBH’s All Things Considered to discuss her recent discovery of some of the universe’s oldest stars, an out-of-this-world identification made the help of MIT undergraduates Hillary Andales, Ananda Santos and Casey Fienberg. “When you meet someone new, you want to know what their name is, how old they are, maybe where they live and what they do, right?” says Frebel. “We do the same with all the astronomical objects in the sky.”
Researchers at MIT have created a noise-blocking sheet of silkworm silk that could “greatly streamline the pursuit of silence,” reports Andrew Chapman for Scientific American. “The silk sheet, which is enhanced with a special fiber, expands on a technology also found in noise-canceling headphones,” explains Chapman. “These devices create silence by sampling the ambient noise and then emitting sound waves that are out of phase with those in the environment. When the ambient and emitted waves overlap, they cancel each other out.”
For the first time ever, researchers at MIT have observed electrons form “fractional quasiparticles without enabling the influence of a magnetic field,” reports Daniel Garisto for Quanta Magazine. This discovery “may carry the seeds of long-sought quasiparticles with stable memories that could underpin a new and powerful approach to quantum computing.”
Researchers at MIT have developed a fiber capable of suppressing sound that is made up of “silk, canvas and other common materials,” reports Charlie McKenna for MassLive. “The silk is barely thicker than human hair and is made by heating the materials and drawing them into a fiber,” explains McKenna. “Since each material flows at the same temperature, they can be pulled into a fiber while maintaining their structure.”
MIT have developed a new ingestible vibrating capsule that could potentially be used to aid weight loss, writes Newsweek’s Robyn White. Prof. Giovanni Traverso said the capsule “could facilitate a paradigm shift in potential therapeutic options for obesity and other diseases affected by late stomach fullness.”
MIT engineers have developed a new adhesive, low-cost hydrogel that can stop fibrosis often experienced by people with pacemakers and other medical devices, reports for Maria Bolevich Interesting Engineering. “These findings may offer a promising strategy for long-term anti-fibrotic implant–tissue interfaces,” explains Prof. Xuanhe Zhao.
