(Credit: Baronb/Shutterstock) Animals from sheep to fur seals share a curious acoustic trait: Their calls feature a vibrato-like trill. Vibrato is the small, quick oscillation in pitch that musicians use to accentuate certain notes. It makes a note sound a bit wobbly and helps catch our attention. It’s found all over the animal kingdom, too — think the staccato “baaaaa’s” of a goat. But animals’ pulsating cries are far more than stylistic. A new study f ...read more

In April 2016, an FDA committee voted not to recommend acceptance of eteplirsen, a drug designed to treat muscular dystrophy.

What followed was an unusual scientific controversy that played out in the peer-reviewed literature, discussed in a Retraction Watch post this week. Following the approval of eteplirsen, Ellis Unger and Robert Califf wrote a letter to ...read more

The impression that your cup of coffee is laughing at you, or that your laundry machine has googly eyes, is uncanny but common. It’s even the subject of a Twitter account called Faces in Things with more than half a million followers. The account has featured winking chairs, moping suitcases and a smug lemon loaf. But this illusion, called face pareidolia, isn’t uniquely human. Monkeys can see it too.  Face pareidolia could be a side effect of humans&rs ...read more

The Folsom point ...read more

Image: Flickr/Joe Loong Mmm… warts! Those fun, fleshy skin growths caused by papillomavirus. They are harmless, and yet… ugh. One of the most common methods of removal is to freeze them off using liquid nitrogen (cryotherapy). But apparently there’s a DIY method that, according to this study, works even better: covering them with duct tape. It takes up to a couple months of diligent tape-wearing to work, but hey, it might help you avoid yet another medical bill. And for tho ...read more
