What happens when “Tom Hanks,” “Tom Cruise” and “Kesha” sit around a table? When the talkers are actually teens using researcher-requested pseudonyms they chose to anonymously discuss their driving habits, the results are surprising, maybe even more so than if the real celebrities got together.
Antiretroviral therapies, or ART, have enabled people with HIV and AIDS to live much longer lives, transforming what was considered a death sentence into a chronic condition. Yet concerns for these patients remain.
Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it’s easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn’t understand why.

When the Department of Defense offers researchers the chance to think big and take risks, and provides the funding to back it up, scientists tend to get really excited.
RNA, once thought to be a mere middleman between DNA and protein, is now recognized as the stage at which a host of regulatory processes can act to allow for flexibility in gene expression and thus the functions of cells and tissues.
Four faculty members at the University of Pennsylvania have been named Fellows of the American Association for the Advancement of Science. They are among a class of 347 researchers that have been awarded this honor by AAAS because of their scientifically or socially distinguished efforts to advance science or its applications
Biological molecules are chiral. Like gloves, they have either left- or right-handed versions that can’t be superimposed on one another. Macromolecules like DNA are also chiral and are exclusively made of building blocks with the same handedness.
When times are good, it pays to be the big fish in the sea. In the aftermath of disaster, however, smaller is better.
