DNA Repair Earned the Nobel Prize in Chemistry, and Here's Why

Yesterday the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry to Tomas Lindahl, Aziz Sancar, and Paul Modrich for their work in mapping out how cells repair damaged DNA. Their research improved our understanding of how our own cells work and helped in the development of cancer treatments, but… »10/08/15 3:50pmThursday 3:50pm

A Few Mutant Genes Can Turn a Stomach Bug into the Black Death

Scientists have long known that one little microbe is responsible for the infamous Black Death plague that decimated Western Europe in the Middle Ages, wiping out roughly one-third of the population. Now they’ve learned more about where it comes from: it takes just a few small genetic changes to turn a mild stomach… »10/07/15 8:20pmWednesday 8:20pm

Here's the Exact Way That the Ice Bucket Challenge Helped ALS Research

Last year’s hugely popular “ice bucket challenge” saw celebrities pouring buckets of ice water over their heads to help fight Lou Gehrig’s Disease (ALS). Skeptics dismissed it as mere “slacktivism,” but researchers told us that the money led directly to a scientific breakthrough. Can slacktivism actually work? »9/16/15 1:20pm9/16/15 1:20pm

We Thought These Microscopic Invertebrates Never Had Sex. Maybe We Were Wrong.

Chances are, you’ve never heard of bdelloid rotifers, strange microscopic creatures that typically live in freshwater ponds and streams. In the grand scheme of things, they’re related to arthropods, a group which includes insects, spiders, and crustaceans. But honestly, they’re in a unique class all their own. And… »9/02/15 2:00pm9/02/15 2:00pm

'Metabolic Switch' Toggles Our Cells to Store or Burn Fat

It seems like cruel fate that some folks are naturally thin, while others have to work tirelessly to control their weight. But in the future, we may be able to level the playing field, because scientists have just discovered a ‘metabolic master switch’ that determines whether fat-producing adipocytes store or burn… »8/22/15 3:00pm8/22/15 3:00pm
