Coated seeds may enable agriculture on marginal lands

A specialized silk covering could protect seeds from salinity while also providing fertilizer-generating microbes. David L. Chandler | MIT News OfficeNovember 25, 2019 Providing seeds with a protective coating that also supplies essential nutrients to the germinating plant could make it possible to grow crops in otherwise unproductive soils, according to new research at MIT. […]

Researchers uncover key reaction that influences growth of potentially harmful particles in atmosphere

NOVEMBER 25, 2019 by University of Pennsylvania Air-quality alerts often include the levels of particulate matter, small clumps of molecules in the lower atmosphere that can range in size from microscopic to visible. These particles can contribute to haze, clouds, and fog and also can pose a health risk, especially those at the smaller end of […]

Producing better guides for medical-image analysis

Model quickly generates brain scan templates that represent a given patient population. Rob Matheson | MIT News OfficeNovember 26, 2019 MIT researchers have devised a method that accelerates the process for creating and customizing templates used in medical-image analysis, to guide disease diagnosis.   One use of medical image analysis is to crunch datasets of […]

Study paves way to better understanding, treatment of arthritis

NOVEMBER 25, 2019 by Steve Lundeberg, Oregon State University Oregon State University research has provided the first complete, cellular-level look at what’s going on in joints afflicted by osteoarthritis, a debilitating and costly condition that affects nearly one-quarter of adults in the United States. The study, published today in Nature Biomedical Engineering, opens the door to better […]

NASA rockets study why tech goes haywire near poles

NOVEMBER 25, 2019 by Miles Hatfield, NASA’s Goddard Space Flight Center Each second, 1.5 million tons of solar material shoot off of the Sun and out into space, traveling at hundreds of miles per second. Known as the solar wind, this incessant stream of plasma, or electrified gas, has pelted Earth for more than 4 billion years. […]

Heating techniques could improve treatment of macular degeneration

NOVEMBER 24, 2019 by American Physical Society Age-related macular degeneration is the primary cause of central vision loss and results in the center of the visual field being blurred or fully blacked out. Though treatable, some methods can be ineffective or cause unwanted side effects. Jinglin Huang, a graduate student in medical engineering at Caltech, suggests […]

Shaking head to get rid of water in ears could cause brain damage, physicists find

NOVEMBER 24, 2019 by American Physical Society Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers at Cornell University and Virginia Tech show shaking the head to […]

Blowing bubbles: Scientist confirms novel way to launch and drive current in fusion plasmas

NOVEMBER 18, 2019 by Raphael Rosen, Princeton Plasma Physics Laboratory An obstacle to generating fusion reactions inside facilities called tokamaks is that producing the current in plasma that helps create confining magnetic fields happens in pulses. Such pulses, generated by an electromagnet that runs down the center of the tokamak, would make the steady-state creation of […]

Physicists determine dripline for fluorine and neon isotopes

NOVEMBER 22, 2019 An international team of physicists with the BigRIPS experiment taking place at the RIKEN Radioactive Isotope Beam Factory in Japan has determined the dripline for fluorine and neon isotopes. In their paper published in the journal Physical Review Letters, the researchers describe how they found the driplines and where their research is headed […]

Chemistry in the turbulent interstellar medium

NOVEMBER 22, 2019 by Harvard-Smithsonian Center for Astrophysics Over 200 molecules have been discovered in space, some (like Buckminsterfullerene) very complex with carbon atoms. Besides being intrinsically interesting, these molecules radiate away heat, helping giant clouds of interstellar material cool and contract to form new stars. Moreover, astronomers use the radiation from these molecules to study […]
