August 22, 2013 Scientists are always looking for a more accurate answer to the question, "What time is it?" Now they've built the most precise atomic clock yet — but it's not just telling time. It has the potential to investigate the accuracy of the General Theory of Relativity.
August 22, 2013 When Republicans on Capitol Hill want to hear reasons not to take strong action on climate change, sometimes they call on Judith Curry to testify. The climatologist has staked out an unusual position on the subject: She says the climate is changing and people are partly responsible, but we shouldn't bother regulating carbon dioxide.
August 22, 2013 Looks like our prehistoric ancestors were bigger foodies than we realized. Archaeologists have found evidence that hunter-gatherers added a hot, mustard spice to their fish and meat thousands of years ago. So meals weren't just about consuming calories. Taste and flavor were important, too.
August 22, 2013 What surgeons see when they open us up and look inside is not pretty — unless you're a surgeon. But when designer Kelli Anderson opens us up, we are feathery, pipe filled, ivory-boned, wired, clean, elegant — just gorgeous. Plus, we are entirely made of colored paper. Check out this new transparent (and interactive!) human body — perfect for kids.
August 22, 2013 NASA says the small object that was caught on video by a spacecraft called the Solar and Heliospheric Observatory was most likely a member of a sun-grazing group of comets known as the Kreutz family.
August 21, 2013 Just a fragment of genes in bat guano was enough for researchers trying to find out how a deadly new virus spreads. It's the first time the Middle East respiratory syndrome virus has been found in an animal, and offers strong evidence that bats carry the virus.
August 21, 2013 Beta agonists, a class of drugs widely fed to cattle and hogs to make them put on weight faster, are coming under increasing scrutiny. Reports suggest animals fed these drugs can seem reluctant to move — lethargic, unable to walk properly — and may die more often, too.
August 21, 2013 WBURThe windswept island about 6 miles off the coast was a haven for a hugely diverse bird population until fishermen decimated the birds' ranks. Puffins have been successfully reintroduced to Eastern Egg Rock, but warming ocean waters may be threatening their ability to survive.
August 21, 2013 An experimental drug rescued three out of seven monkeys from lethal doses of Ebola. The study marks the first time researchers have shown that a drug can successfully treat Ebola in animals even after the infection is well underway.
August 21, 2013 Runners often ask themselves, "Why am I doing this? Why do I want to make myself hurt so?" With help from the webcomic The Oatmeal, we might have an answer.
August 20, 2013 By precisely measuring footfalls, scientists discovered that healthy human feet bend and flatten much like the feet of tree-dwelling apes. And the flex in one person's foot can vary a lot from one step to the next.
