Until recently cancers were seen as lifestyle and genetic diseases, brought on by exposure to carcinogens or a mutated gene. Recent studies are linking microbes to many diffe... Read More
Although we all know that sneezes and coughs transmit infections, little research had been done to model how they work. To address this knowledge gap, Lydia Bourouiba and John Bush of MIT’s Applied Mathematics Lab used high speed cameras and fluid mechanics to reveal why we’ve grossly underestim... Read More
If you aren’t familiar with the TEDEd series of animated videos, you should be. The series pairs professional educators with top-notch animators to create short video “lessons” on a huge variety of topics in science, medicine and history. The latest episode features several of the early attempt... Read More
Researchers have developed new insight into a rare but deadly brain infection, called progressive multifocal leukoencephalopathy (PML). This disease – which is caused by the JC virus – is most frequently found in people with suppressed immune systems and, until now, scientists have had no effect... Read More
Ebola is transmitted from person to person through direct contact with the body or with body fluids of an infected person. Ebola virus is NOT a respiratory virus and is NOT transmitted through the air. It is not a gastrointestinal virus either, so it is NOT generally transmitted via water or foo... Read More
Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional res...

Biologists dissected tissue samples from an oarfish carcass found in California and discovered the creature was hosting quite a few parasites.
“Our findings say that these are actually majorly parasitized fish,” says Armand Kuris, professor of zoology at the University of California, Santa Ba... Read More
A new technology under development by an academic–industry partnership protects oral vaccines from destruction by the digestive system. From the mouth to the small intestine, the digestive system presents a series of challenges designed to protect us by killing ingested bacteria. If a microbe su... Read More
A newly developed antifungal, isavuconazole, is as effective as an existing drug, voriconazole against invasive mold disease in cancer patients with less adverse ... Read More
Community ecologist Sunshine Van Bael of the Smithsonian Tropical Research Institute in Panama details her work and role in understanding the world's first known farmers leafcutter ants, plant-insect-fungal interactions, endophytic fungi, and their dynamic relationships with the surrounding envi...

A form of bacteria responsible for respiratory illness, including the deadly pneumonia known as Legionnaire's disease, may be able to grow in windshield washer fluid and was isolated from nearly 75% of school buses tested in one district in Arizona. The participant will discuss findings from ... Read More
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-... Read More
For nearly a decade, Brooklyn-based artist, photographer, and Guggenheim Fellow Rachel Sussman has been traveling the globe to discover and document its oldest organisms — living things over 2,000 years of age. Her breathtaking photographs and illuminating essays are now collected in The Oldest ... Read More
One of the most critical biological advances in the past decade was the discovery that the introduction of four simple genetic factors can turn a fully mature adult cell back into an embryonic-like state, a process called reprogramming.

Using animals to test drugs destined for humans is controversial, with critics arguing there are other ways to ensure new medicines are safe and effective. But the scientists who carry out the research say animal studies remain necessary.
It is estimated that in the UK around three million mi... Read More

If we could somehow rewind the history of life to the dawn of the animal kingdom, it would be unlikely that we humans would ever evolve, the evolutionary biologist Stephen Jay Gould argued. The history of life was shaped by too many flukes and contingencies to repeat its course.

By evaluating the bacteria and fungi found in fossilized feces, microbiologists are providing evidence to help support archeologists' hypotheses regarding cultures living in the Caribbean over 1,500 years ago. Researchers discuss how the analysis of 1,500-year-old coprolites from archeologica... Read More
