Ikea's New Chainless Bike Never Rusts

Dealing with a rusty bicycle chain can be a messy affair, but an innovative new bike from Ikea solves that pesky problem. The furniture retail giant recently introduced its new "Sladda" bike, which uses an oil-free and corrosion-resistant drive belt rather than a metal chain. The drive belt is designed to last about 9,320 miles (15,000 kilometers), which is about two to three times longer than a typical steel chain, according to Ikea.

A robot to teach kids coding

By Ben Gruber Cambridge, MASS (Reuters) - A robot named Root has been developed to expose kids of all ages to coding in a way that brings the often daunting world of computer science to life.   Root looks like a smoke detector but is actually a sophisticated robot. Zivthan Dubrovsky of Harvard's Wyss Institute recalls testing out Root with kids for the first time.  "If you ask kids can you make a text based java script line follower?

Does The Full Moon Make Kids Hyper? Here’s What Science Says

Kids really do sleep less when there's a full moon, but only by a few minutes, according to a new study that included children from a dozen countries. What's more, the study failed to find a link between the occurrence of the full moon and kids' activity levels, debunking the myth that kids are more hyper during a full moon. The study "provides solid evidence … that the associations between moon phases and children's sleep duration/activity behaviors are not meaningful from a public health standpoint," the researchers, from the Children’s Hospital of Eastern Ontario Research Institute in Ottawa, Canada, wrote in the March 24 issue of the journal Frontiers in Pediatrics.

Chemicals in Fast Food: Should You Be Worried?

People who eat fast food may be ingesting potentially harmful chemicals called phthalates, a new study finds — another reason to avoid eating these typically unhealthy foods, experts say. However, experts emphasize that most Americans are exposed to phthalates every day, and it's not clear exactly how much of this exposure comes from fast food. Still, for people who want to reduce their exposure to phthalates, a chemical used in plastics that can leach into foods, reducing fast food consumption could be one way to do this, said Dr. Kenneth Spaeth, chief of occupational and environmental medicine at Northwell Health, a health care network headquartered in Great Neck, New York.

The Real Reason AI Won’t Take Over Anytime Soon

Artificial intelligence has had its share of ups and downs recently. In what was widely seen as a key milestone for artificial intelligence (AI) researchers, one system beat a former world champion at a mind-bendingly intricate board game. In early March, a Google-made artificial intelligence system beat former world champ Lee Sedol four matches to one at an ancient Chinese game, called Go, that is considered more complex than chess, which was previously used as a benchmark to assess progress in machine intelligence.

Turn Your Photos Into Fine-Art 'Paintings' on Free Website

Users can upload photos and choose an art style from a selection of well-known paintings, illustrations and sketches in the online database — or even add new ones. "The algorithm uses so-called deep, artificial neural networks — a mathematical model built of units called neurons linked with each other," Kidzi?ski told Live Science in an email. One example, shared by Twitter user @claudeschneider, combined a photograph of a dancer posing in a rocky landscape with the Picasso painting "Woman with Mandolin" (1910), to create a Cubist ballerina.

Lost Wright Brothers' 'Flying Machine' Patent Resurfaces

The Wright brothers didn't wait for the patent to be granted to take flight. On Dec. 17, 1903, the brothers lofted their flying machine into the air for 12 seconds, flying 120 feet at Kitty Hawk, on North Carolina's Outer Banks.

Neanderthal Table Manners: They Used Toothpicks, Too

Neanderthals, the closest known extinct relatives to humans, probably had to pick annoying bits of food out of their teeth from time to time. The bits of bark likely came from toothpicks or possibly wooden tools used as a third hand during crafting, said the new study, published in the April issue of the journal Antiquity.

Shackled Skeletons Could Be Ancient Greek Rebels

A trove of shackled skeletons unearthed in a mass grave near Athens may have once belonged to the followers of a tyrant who sought to overthrow the leader of ancient Greece. "These might be the remains of people who were part of this coup in Athens in 632 [B.C.], the Coup of Cylon," said Kristina Killgrove, a bioarchaeologist at the University of West Florida, in Pensacola, who was not involved in the current study. The mass grave was uncovered as archaeologists were excavating a huge cemetery in the ancient port city of Phaleron, just 4 miles (6.4 kilometers) from Athens.
