Why Do Creationists Place So Much Importance On A Prehistoric Mollusk?

Along the Grand Canyon section of the Colorado River sits a canyon that was carved out of redwall limestone by flowing water. There, the rocks contain fossils of the orthocone nautioloid, which lived 500-200 million years ago. But a prominent young-Earth creationist says they're solid proof of Noah's flood. » 8/15/14 8:45am Friday 8:45am

Yellowstone Is Not Erupting And Killing Us All, Again

Someone, somewhere, decided that Yellowstone was in a period of unusually high geologic activity and facing major road closures and evacuations, and therefore was in danger of imminent eruption. This is all so ridiculously untrue, I hesitate to even use the "debunkery" tag because it's hard to believe it needs… » 8/10/14 6:20pm 8/10/14 6:20pm

Reality Check: Most Scientists Never Believed In "Global Cooling"

Climate-change deniers like to remind us how, in the 1970s, scientists all believed the Earth was heading for another ice age. So why should we believe the doomsayers who now claim the opposite? Here's why: Most scientists rejected the "global cooling" theory and, even then, were convinced the real problem was… » 8/08/14 11:00am 8/08/14 11:00am

Don't Get Too Excited About NASA's New Miracle Engine

News spread quickly this week that a propulsion system said to violate the laws of physics had been validated by no less an authority than NASA itself. Could a fuel-less space drive propelled by microwave thrust –something once deemed impossible – actually be possible? We spoke with some experts. Let's just say… » 8/04/14 11:30am 8/04/14 11:30am

How a Mysterious Body Part Called Fascia Is Challenging Medicine

Fascia is a web of fibrous tissue that permeates the body, but is it really the "Cinderella Tissue" that new age therapists, Rolfers, and yoga instructors suggest? The fascial system is still a medical mystery. But that could soon change, thanks to an unlikely alliance between researchers and alternative therapists. » 7/29/14 12:07pm 7/29/14 12:07pm

Tylenol No More Effective Than Placebo in Treatment of Back Pain

A 3.5-year, double-dummy, randomized, placebo-controlled trial, conducted across 235 primary care centers in Sydney Australia has found that paracetamol (trade name: Tylenol, aka acetaminophen), one of the most widely used analgesics in the world, is no more effective in the treatment of back pain than placebo. » 7/24/14 3:40pm 7/24/14 3:40pm

Family That Walks On All Fours Not A Product Of 'Reverse Evolution'

In Turkey, there's a family with an apparent genetic disorder that causes them to walk on all fours. Scientists have speculated that they're an example of "devolution" — a backwards step towards our quadrupedal past. A new paper challenges this assumption, offering a far more reasonable explanation. » 7/17/14 7:40am 7/17/14 7:40am

That ISIS "Caliphate Map" Is Bogus, So Stop Freaking Out

Judging from the comments on Twitter, a lot of people are panicking over the map that's appeared on ABC News, purporting to show ISIS' "five-year expansion plan" for conquering vast territory. Let's stop this meme right now, shall we? ISIS didn't even make the map—and a neofascist group is circulating it. » 7/01/14 12:00pm 7/01/14 12:00pm

What Sound Did T. rex Actually Make?

It's an iconic scene in every dinosaur movie: the huge, conquering carnivorous theropod rears back and lets out a terrifying bellow. But how close to reality are these sounds? Do we have any ways of using science to figure out what dinosaurs and other stem-birds may have sounded like? Do we have evidence that they… » 6/15/14 1:00pm 6/15/14 1:00pm
