We’re not the only species that knows the difference between a face-to-face chat and a remote one. Research out of Vienna shows cows prefer live human voices to recorded ones. Plus: on National Chocolate Day, we pay a visit to the world's largest chocolate moose, in Scarborough, Maine.
A sensor developed at MIT uses a set of microneedles to push through packaging and determine whether the food inside is safe to eat, which could prevent food waste and help head off outbreaks of salmonella. Plus: did you know China is apparently home to several thousand glass footbridges, where you can walk across and see what's underneath?
Research at the University of Oslo shows that humans have an almost unstoppable urge to start moving when the music starts - though, of course, some kinds of music and other factors can lead to more moving than others. Meanwhile, in Austin, Texas, you can (virtually) move through some of the city's most unusual houses through a virtual Weird Homes tour.
"Ambush predators" like lions go after livestock while those animals aren't looking. So scientists at the University of New South Wales tested a theory in Botswana: what if we painted eyes on the back ends of cattle so the lions thought they were watching? Plus: National Roller Coaster Day is coming up, make your plans to visit Japan's famous pedal-powered SkyCycle.
Judging by my kids' toy collections I thought fluorescents were already about as bright as possible. But chemists at Indiana University and the University of Copenhagen have found a way to make the brightest fluorescent materials ever made. Plus: for World Elephant Day, meet Lucy, the elephant-shaped hotel on the Jersey Shore.
On this day in 1999 a court rules in a case involving a guy who tried to use a huge number of points in a Pepsi reward program to buy a fighter jet, which the soda maker had jokingly offered in one of its ads. It didn't work, but still, an A for effort. Plus: there's a new uncuttable substance that might make for a great bike lock.
Maybe everyone in junior high was right: the clothes you wear really can make you cool! At least if those clothes are the new fabric developed in China with a kind of cooling system embedded inside. Plus: it's National Chocolate Chip Cookie Day, so let's find out about the largest chocolate chip cookie of all time.
Researchers at the University of Washington call it a "GoPro for beetles" - a ultralight, wireless, steerable camera that can ride on the back of a bug. And it's pretty effective at letting us see what these bugs see. Plus: a new online chart tracks the vocal range of famous pop singers, by measuring the highest and lowest notes they ever sung on a recording.
Our entire show is based on the idea that we might say something interesting enough that it might get you to perk up your ears, figuratively speaking. Or, as a team at Saarland University has found, maybe not so figuratively speaking. Plus: a sculpture garden in Dublin, Ohio pays tribute to ears of a different kind.
Our planet is sometimes called the big blue marble, but Professor Shiladitya DasSarma of the University of Maryland-Baltimore has a hypothesis that suggests if you look way back in time, Earth may have once been bright purple. Plus: meet a guitar with LEDs built into its body that can flash in time with the music.
