Loren Grush of Popular Science writes about a new type of antibiotic developed by MIT researchers that could help kill drug-resistant bacteria. “[T]he team developed their own gene-editing system, capable of turning off certain bacterial genes that spur antibiotic resistance,” Grush explains.
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.
Financial Times reporter Clive Cookson highlights the work of MIT researchers in identifying a new culprit for the Earth’s largest mass extinction. While volcanic activity did contribute to the extinction, Cookson reports, MIT researchers found the main cause was methane-producing microbes.
The Huffington Post reports on new research from MIT that indicates microbes may have been responsible for Earth’s largest mass extinction. The “Great Dying,” which took place 252 million years ago, wiped out 90 percent of all species.
“These microbes of death were so small, that 1 billion of them could fit in a thimble-full of ocean sediment, and yet, they were almost responsible for killing off all the life on our planet,” writes Los Angeles Times reporter Deborah Netburn about new research from MIT that indicates microbes may be responsible for the end-Permian mass extinction.
“A microbial feeding frenzy may have fueled the biggest mass extinction in Earth's history,” writes Tia Ghose for CBS News about new research by Professor Daniel Rothman and Gregory Fournier that suggests microbes may be responsible for the Earth’s largest mass extinction.
Washington Post reporter Fred Barbash highlights new MIT research that shows that a microbe called “Methanosarcina” triggered the largest mass extinction in Earth’s history.
Reporting for NPR’s Morning Edition, Christopher Joyce features new work by Professor Daniel Rothman that indicates the world’s largest mass extinction may have been caused by microbes.
MIT researchers have found evidence that methane-producing microbes may have triggered the largest mass extinction in Earth’s history, reports Will Dunham for Reuters.
