It's just crazy enough to work.

A gene normally responsible for repairing DNA may have a darker side when produced in excess. Cancer treatment is increasingly moving beyond where a tumor forms and focusing instead on the genetic flaws that drive it. Now, researchers at Penn State College of Medicine have identified an unexpected DNA repair gene that could help expand [...]

I t was the dead of winter in Boston. The surface of the Charles River was frozen solid. But Zachary Kelso braved the biting cold to finally put to rest a mystery that has haunted neuroscience labs for over half a century. To do that, Kelso, a research assistant in the Harvard lab of the neuroscientist Sam Gershman, needed some worms. Specifically, planarians: arrow-headed flatworms…

New DNA evidence reveals bed bugs tracked human expansion from ancient caves to modern cities.

Scientists have uncovered evidence that tiny microbes living inside fish may be helping shape the chemistry of the world’s oceans. The new study, led by former graduate student Anthony Bonacolta at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, suggests that bacteria in fish intestines may work together with their hosts [...]
