A team led by Professor Timothy Lu has developed a new class of antibiotic that can selectively kill bacteria based on their genes, reports Michael Eyre for BBC News. "This is an enabling toolkit for the basic scientists to now start probing these systems a little bit better,” says Lu.
Researchers at MIT have developed a waterproof glue based on the proteins that allow shellfish to cling to rocks, reports Brooks Hays for UPI. "We're trying to figure out if by adding other mussel foot proteins, we can increase the adhesive strength even more and improve the material's robustness," said Professor Timothy Lu.
CBS News reports that MIT engineers have identified several combinations of genes that make bacteria more vulnerable to antibiotics. This research could help in the fight against “superbugs,” drug-resistant bacteria that kill at least 23,000 people per year in the U.S.
Lina Zeldovich of The Atlantic writes about how Prof. Eric Alm and one of his graduate students tracked their bacterial fluctuations for a year to better understand how daily activities influenced their microbiome. “We just don’t know much about the functional role of any of these bugs,” says Alm.
Dietary changes can alter human gut bacteria, Mary Elizabeth Dallas reports in a U.S. News & World Report article on a new MIT study on the role of bacteria in the digestive tract. “These fluctuations could lead to monitoring systems that might help detect and ease flare-ups for people with certain chronic illnesses, such as inflammatory bowel disease (ulcerative colitis and Crohn's disease),” Dallas writes.
In a piece for National Geographic, Ed Yong writes about how a team of scientists from MIT has found a corresponding rhythm of behavior amongst marine bacteria. “The study reveals the power of sophisticated sampling devices for studying ocean features that were heretofore inaccessible,” says MIT Prof. Penny Chisholm.
Lauren Hitchings of New Scientist reports on findings showing that marine microbes exhibit daily patterns of behavior. “The researchers think this might be a result of the low nutrient levels in the open ocean, and the need for organisms to rely on one another for metabolic functions,” writes Hitchings.
NPR’s Joe Palca reports on MIT Professor Rohit Karnik’s work to develop a cheap and effective way to filter water. Karnik’s new solution is a filter made from a pinewood branch peeled of its bark.
Boston Globe reporter Carolyn Johnson writes that Professor Rohit Karnik has developed a, “promising next-generation water filter that might be effective, cheap, and biodegradable.”
“The function of xylem's filtration formed the basis of a paper published this week by a team from the Massachusetts Institute of Technology,” Jason Tetro writes of Rohit Karnik’s work with water filtration in the Huffington Post. “The premise was that xylem could help to filter water and make it safe to drink.”
The New York Times examines the work of MIT startup OpenBiome, which is aimed at providing doctors with, “safe, inexpensive fecal material from screened donors to treat patients with Clostridium difficile.”
