A study led by Prof. John Hansman suggests that slower planes would significantly reduce noise on the ground. “It turns out engines aren’t the major culprit anymore,” writes Scott McCartney for The Wall Street Journal. “It’s the “whoosh” that big airplanes make racing through the air.” 

A working paper published by MIT’s Center for Energy and Environmental Policy Research found that 74% of rideshare drivers earn less than the minimum wage for their state. “The report also showed a huge turnover rate among drivers, with half to 90 percent quitting after a short time,” writes Carolyn Said for the San Francisco Chronicle.

Mary Beth Griggs writes for Popular Science about a new Nature study where researchers have identified cold hydrogen dating back to 180 million years post-big bang. “Some of the radiation from the very first stars is starting to allow hydrogen to be seen,” says Alan Rogers of the Haystack Observatory.

Prof. John Gabrieli writes about new research that uses brain scans to predict who will be receptive to certain therapies for mental illness. "Brain scans to tailor treatments embody a new form of personalized medicine, an approach that often relies on customizing therapies based on an individual's genetics," Gabrieli writes for Scientific American.

This April, NASA will launch the Transiting Exoplanet Survey Satellite, or TESS, which will measure the masses of at least 50 “potentially Earth-like worlds,” writes Irene Klotz for Scientific American. “We’re finding the particular star that actually potentially hosts an exoplanet around it,” said senior research scientist George Ricker, the lead scientist on TESS.

The Nature Podcast, hosted by Adam Levy and Shamini Bundell, highlights research from the Haystack Observatory and Prof. Li-Huei Tsai’s findings around Alzheimer’s and its connection to brain waves.

A robotic carpenter developed by CSAIL is pre-cutting wood for flat-pack furniture, making assembly safer and more efficient. Called AutoSaw, the idea “was not to replace human carpenters but to allow them to focus on more important tasks such as design,” writes Dave Lee for the BBC.

Heidi Ledford of Nature highlights the modification of an enzyme that will allow for enhanced CRISPR-Cas9 gene editing, led by Broad Institute researcher David Liu. Ledford explains that while Liu believes the enzyme could be a staple in the lab, he also adds that “it will need more testing before its full potential becomes clear.”

Led by senior research scientist Rolland Pellenq, students in the School of Engineering developed a model “that links a city’s ‘texture’ to its night-time UHI (Urban Heat Index),” writes Laurie Winkless for Forbes. The team hopes their research will influence future urban development, especially in very hot or cold climates.

David Grossman of Popular Mechanics writes about AutoSaw, a system developed by CSAIL researchers that assists in custom build carpentry projects. The system is designed “to split the difference between machine-built quality and unique customization” and requires human assembly after the pieces are cut, explains Grossman.

Hydrogen detected via radio waves by MIT researchers indicates the presence of stars 180 million years after the Big Bang, reports Will Dunham of Reuters. The radio waves also indicate that the universe was likely twice as cold as was previously believe, which Research Affiliate Alan Rogers suggests “might be explained by interaction between the gas and dark matter.”

Prof. Li-Huei Tsai found that use of a small flickering light could prevent plaque-forming proteins in the brains of mice - a practice that has potential to combat Alzheimer’s disease. “The work offers the possibility of forestalling or even reversing the damage caused by such conditions without using a drug,” writes Helen Thomson for Nature.

Autosaw, the robotic carpenter developed by researchers from CSAIL, can cut pieces for furniture building, as long as you provide the raw materials. “It’ll cut pieces to shape, drill the necessary holes and even move them around the workshop for you,” writes Thomas Tamblyn for Huff Post.

Research led by Prof. Shigeru Miyagawa finds that cave art may be symbolic of early human languages. “The cognitive functions needed to transfer acoustic sounds to pictures are the same cognitive functions needed in language,” senior researcher Cora Lesure tells Sarah Gibbens of National Geographic.

Alan Rogers of MIT's Haystack Observatory co-authored a study that identifies the earliest traces of hydrogen in the universe. The gas is “from 180 million years after the Big Bang,” writes Elise Takahama for The Boston Globe, which suggests that stars would have appeared around this time, creating a “cosmic dawn.”
