MIT researchers have found that when raindrops hit the ground they release aerosols, which produce a distinctive scent, reports Avianne Tan of ABC News. Prof. Cullen Buie explains that the findings also show how bacteria could spread through “chemicals being carried by aerosols."
“It turns out tiny bubbles may be to thank for that earthy smell we get after it rains, according to a study from researchers at the Massachusetts Institute of Technology,” writes Lori Grisham for USA Today. “The study may serve as a jumping-off point for other research about chemicals in soil.”
MIT researchers have discovered why rainfall produces such a distinctive smell, reports Rachel Feltman for The Washington Post. The researchers examined high-speed footage of raindrops and found “when rain hits the ground [it] may be sending out signature smells that get carried away on the wind."
MIT scientists have uncovered the mechanism behind why rainfall can produce such a distinctive scent, writes Macrina Cooper-White for The Huffington Post. The researchers found that when rain hits a porous surface, tiny bubbles form. When the bubbles burst, they release aerosols, which carry the “rainlike aroma” into the air.
Using high-speed cameras, MIT researchers have captured how the smell of rain is released into the air, the BBC reports. “The results may help to explain how some soil-based diseases are spread and the authors are now studying whether contaminants such as E. coli can be spread significantly via rainfall,” the BBC explains.
In a piece for Salon, Paul Rosenberg writes about Prof. Jeremy England’s theory about the origins of life. England’s theory, based on the principals of thermodynamics, shows that under certain conditions “where life is possible…it is also quite probable, if not, ultimately, inevitable,” Rosenberg explains.
Professor Jeremy England appears on WGBH television’s Greater Boston to discuss his work examining the origins of life. England explains his theory that, from the perspective of physics, energy played a role in the formation of life.
Writing for Scientific American, Jennifer Ouellette features Professor Allan Adams research on black holes on her list of the 20 best physics papers of 2014. “We showed that when you throw stuff into a black hole, the surface of the black hole responds like a fluid,” says Adams.
Carolyn Johnson of The Boston Globe reports on Prof. Benjamin Weiss’ research examining evidence that the moon had a magnetic field. Johnson writes that analysis of moon rocks has shown that the moon "had a magnetic field caused by an ancient core dynamo.”
Presidential Medal of Freedom recipient Prof. Mildred Dresselhaus speaks with Julianna Goldman of CBS Evening News about her career at MIT and what continues to inspire her to come to work seven days a week. "Every year there's something new that comes along that's too exciting to quit," says Dresselhaus.
Scientific American reporter Charles Choi writes that MIT researchers have uncovered evidence that magnetic fields played a role in forming the early solar system. "Magnetic fields can introduce viscosity into the disk, essentially making the gas in it more sticky," explains MIT graduate student Roger Fu.
Nidhi Subbaraman of BetaBoston writes that Institute Professor Mildred Dresselhaus has been honored with a Presidential Medal of Freedom. Subbaraman explains that Dresselhaus conducted early research into the electric properties of graphite, “and her work led to the discovery of graphene, the atom-thin carbon sheets that are expected to revolutionize the way we work with electronics.”
David Jackson of USA Today writes about the recipients of the Presidential Medal of Freedom, including two MIT honorees, Institute Professors Mildred Dresselhaus and Robert Solow. Dresselhaus was honored for “deepening our understanding of condensed matter systems and the atomic properties of carbon,” while Solow was recognized for “laying the groundwork for much of modern economics.”
Science reporter Vijaysree Venkatraman speaks with Presidential Medal of Freedom recipient Professor Mildred Dresselhaus about her career, in particular what it was like to be a female professor in a male-dominated field. Her advice for other women aspiring to work in academia: “Don’t give up.”
Researchers from MIT have detected the brightest pulsar ever recorded, reports Brook Hays of UPI. “Despite its small dimensions and modest mass, the pulsating dead star is burning with the energy of 10 million suns,” writes Hays.
