A study co-authored by Prof. Josh Tenenbaum finds that learning a new language should start before age 10 to achieve a native-like grasp of the grammar, reports BBC News. People remain highly skilled language learners until about 17 or 18, but then fall off, which Tenenbaum says could be due to “a biological change” or “something social or cultural.”
Led by graduate student Adam Haar Horowitz, researchers at the Media Lab have developed a device, known as Dormio, which aims to understand how humans can control the “semi-lucid” phase before sleep, called “hypnagogia,” reports Laura Yan for Popular Mechanics. "I have no doubt that Hypnagogia holds applications for augmenting memory, learning, and creativity,” says Haar Horowitz.
The Media Lab’s Fluid Interfaces Group has developed a device “to influence and extend the semi-lucid sleep state called hypnagogia,” writes Jesus Diaz of Co.Design. Called Dormio, the system is a “first step towards creating interfaces that allow us to interact with our subconscious the same way we interact with our conscious mind,” explains Diaz.
Research by Prof. Susumu Tonegawa suggests that a specific region of the hippocampus plays a role in how memories can trigger a physical stress response, writes Fiona McMillan for Forbes. The findings, McMillan notes, are “providing new insight into the complex interplay between emotion, stress and memory.”
Researchers at the Tangible Media Group have developed “programmable droplets” of water that can be used to communicate words. “One potential application is a mirror that, when steamed, allows someone to display a message from a smartphone” writes Jesus Diaz for Co.Design. “The larger idea is to provoke surprise and delight, the way only the natural world can.”
NASA’s recently launched Transiting Exoplanet Survey Satellite (TESS) “will spend the next two years scanning 200,000 stars looking for any exoplanets orbiting them,” explains New Scientist. In about two months, once the satellite is in orbit and its cameras are tested, “there’ll just be a flood of information,” says MIT’s George Ricker, the principal investigator on TESS.
Writing for The Verge, Angela Chen highlights advances in AI that are allowing researchers to discover and understand new materials at a rapid pace. Chen cites a study co-authored by Assistant Prof. Elsa Olivetti, who “developed a machine-learning system that scans academic papers to figure out which ones include instructions for making certain materials.”
Using several comparative models, a new study led by MIT researchers reveals that China’s pledge to peak its carbon emissions by 2030 could cut down on as many as 160,000 premature deaths. “Politically, the research confirms why Chinese officials have their own internal reasons to cut CO2 even though the U.S. is abandoning Paris and disengaging internationally on climate,” writes Ben Geman for Axios.
A team led by research scientist Ming Dao has made diamond nano-needles that can bend without breaking and snap back into to their original position, New Scientist reports. “The tiny needles had very little room for defects in their crystal structure, so they could bend without snapping,” the article explains.
A study led by research scientist Nick Obradovich found that people’s behavior on social media may be influenced by weather conditions. “Positive posts increased as the temperature rose,” reports Robert Preidt in US News & World Report, but “precipitation, humidity levels of 80 percent or higher, and high amounts of cloud cover were associated with a greater number of negative posts.”
A new study finds that a 4% reduction in China's carbon emissions by 2030 could save a total of $464.5 billion in healthcare costs, writes Chase Purdy for Quartz. “We have all these policy goals for a transition toward a more sustainable society,” says Associate Prof. Noelle Selin. “Mitigating air pollution, a leading cause of death, is one of them, and avoiding dangerous climate change is another.”
Forbes contributor Brid-Aine Parnell describes new research from MIT and others who discovered that even though diamonds are hard and brittle, “needle nanodiamonds can stretch by as much as 9%.” Because of this, such nanodiamonds could “be biocompatible for vivo imaging, optoelectronics or even delivering drugs into cancer cells,” writes Parnell.
In this one-minute read for Fast Company, Michael Grothaus quips that “40 is the new 20,” based on a new working paper by Sloan Prof. Pierre Azoulay and graduate student Daniel Kim. They found that “when it comes to entrepreneurship, the average successful business founder is 42 years old,” reports Grothaus.
A device developed by MIT researchers allows people to be aware of the brief period between wakefulness and sleep or hypnagogia, reports Daniel Oberhaus of Motherboard. “The system is meant to prevent the user from falling deeper into sleep, effectively suspending them in an extended state of hypnagogia,” Oberhaus explains.
In a VICE News Tonight climate segment, MIT postdocs Volodymyr Koman and Seon-Yeong Kwak explain their technique for making plants glow in the dark to a first-grade class in Boston. Following a demonstration mixing plant glucose with the specialized nanoparticles, one student exclaims in disbelief, “no battery or anything!”
