Indian start-up launches shoes that show you the way

"Wizard of Oz" heroine Dorothy only had to click her ruby red slippers together and they would spirit her home to Kansas.

Now, an Indian high-tech start-up is promising to do the same in real life with a new, GPS-enabled smart sports shoe that vibrates to give the wearer directions.

The fiery red sneakers, which will also count the number of steps taken, distance travelled and calories burned, will go on sale in September under the name LeChal, which means “take me along” in Hindi.

The shoes come with a detachable Bluetooth transceiver that links to a smartphone app to direct the wearer using Google maps, sending a vibrating signal to indicate a left or right turn.

They are the brainchild of 30-year-old Krispian Lawrence and Anirudh Sharma, 28, two engineering graduates who founded their tech start-up Ducere in a small apartment in 2011 with backing from angel investors and now employ 50 people.

"We got this idea and realised that it would really help visually challenged people, it would work without any audio or physical distractions," said Lawrence in an interview with AFP.

"But then we were trying it out on ourselves and suddenly we were like, ‘wait a minute, even I would want this,’ because it felt so liberating not having to look down at your phone or being tied to anything."

"The footwear works instinctively. Imagine if someone taps your right shoulder, your body naturally reacts to turn right, and that’s how LeChal works."

If A Fish Grows Up On Land, Will It Learn To Walk?

Flipping your fins actually does get you pretty far.

by Lauren Grush

The old idiom about “being a fish out of water” just lost some of its luster. Researchers from McGill University in Canada successfully trained a group of fish to live on land and strut around.

The idea was to simulate what might have happened 400 million years ago, when the first group of ancient fish moved from water to land, eventually evolving into the amphibians, reptiles, birds and other animals roaming the Earth today. The researchers wanted to see if their land-dwelling fish looked and behaved similarly to the ancient fish, based on what has been learned about them from fossil records.

For their experiment, the research team raised 111 juvenile Polypterus senegalus – African fish also known as the “dinosaur eel” — on land. These fish already look a lot like the ancient fish that evolved millions of years ago, and they’re already capable of “walking” with their fins and breathing air.  According to the Verge, their terrestrial environment had mesh flooring covered in pebbles, as well as 3 millimeters of water, so the fish didn’t dry out completely…
