Karen Hopkin of Scientific American writes about a new method developed by MIT researchers for increasing the size of tissue samples to allow for better observation. Thus far, the researchers have used the new technique to “peer into the brains of mice, fruit flies and zebrafish,” Hopkin explains.
Using a polymer found in diapers that swells on contact with water, Prof. Ed Boyden and his colleagues have developed a method for enlarging tissue samples to allow for better 3-D imaging, writes Jessica Hamzelou for New Scientist. The team can enlarge samples to more than four times their original size, Hamzelou reports.
John Markoff writes for The New York Times about a new technique for observing minuscule features in biological samples developed by Prof. Ed Boyden and his colleagues. The researchers “were able to increase the physical size of cultured cells and tissue by as much as five times while still preserving their structure,” Markoff explains.
Rebecca Jacobson of the PBS NewsHour reports that MIT researchers have developed a new technique to enlarge tissue samples, allowing scientists to create high-resolution images of specimens. Prof. Ed Boyden explains that “now you can see tiny structures with your own eyes.”
Carolyn Johnson of The Boston Globe writes that MIT researchers have developed a new way to enlarge microscopic lab samples to allow for more-detailed imaging of brain cells. The new technique “may offer an inexpensive way for people to examine fine cellular structures at a detailed level using off-the-shelf ingredients.”
A team of MIT researchers has devised a new method for obtaining super-high resolution images from lab microscopes, writes Malcolm Ritter for the AP. The researchers found that by permeating a tissue sample with a specialized version of sodium polyacrylate they were able to enlarge the sample, making them easier to image.
Cynthia Graber of Scientific American reports that MIT researchers have developed a new technique that turns a smartphone into a sensor that can detect hazardous gases and environmental pollutants. "The method was tested with ammonia, cyclohexanone and hydrogen peroxide. And the tags could sense the substances at levels of a few parts per million,” reports Graber.
MIT engineers are developing a paper test that can identify Ebola, writes BetaBoston reporter Nidhi Subbaraman. Prof. Lee Gehrke’s goal is to develop a “cheap, disposable front-line detector for this disease that many people can get their hands on — and fast,” Subbaraman reports.
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.
A new technique developed by MIT researchers for capturing waste heat that can be used to produce electricity has been named one of 10 World Changing ideas by Scientific American, reports Ryan Bradley. “This is something attractive,” says Dr. Yuan Yang, a postdoctoral associate at MIT, “because low-grade heat is everywhere.”
Boston Globe reporter Callum Borchers writes about how MIT researchers have developed a new coating that could reduce the risk posed by ingesting batteries. The battery has “been shown in lab tests to deactivate an ingested battery without compromising its performance in electronic devices,” writes Borchers.
A system developed by Prof. Alfredo Alexander-Katz allows microscopic devices to navigate a cell’s surface, reports Alissa Zhu for Popular Science. “Doctors could use them to provide real-time updates on internal structures or distribute drugs to specific targets within a body.”
Scientists at the Singapore-MIT Alliance for Research and Technology have discovered a new way to test for malaria using magnets, reports Charlotte Seager of The Guardian. The new method will allow for individual diagnostic tests to be performed for less than 10 cents.
Nicole Skinner writes for Nature about how MIT researchers have developed a new technique to test for malaria. The new method only requires a tiny droplet of blood to check for malaria and can provide a diagnosis within minutes.
Andrea Timpano of Boston Magazine reports on the new biodegradable nanoscale film developed by MIT researchers. The film could be used to deliver long-lasting medication for patients suffering from chronic pain.
