New research: Danish nasal filter more than halves symptoms of hay fever
Clinical trials carried out by Aarhus University show that the use of a mini filter prevents pollen inhalation and results in significantly fewer symptoms such as sneezing, watery eyes and drowsiness. These results have just been presented in Barcelona.
For 25 years, inventor Keahi Seymour has dreamed of running with the speed and loping gait of an animal. His inspiration struck at age 12, while he was watching a program about kangaroos. “The announcer said it moves at such an efficient gait by using its Achilles tendons as springs,” Seymour says. “I thought, ‘Why not replicate that in a device that could propel a human?’ ” He began sketching footwear using ostriches, which, he discovered, run more like humans, as his model.
By the age of 17, he had built his first prototype using old Rollerblade boots, steel tubing, and bungee cords. Then, he built some 200 more. Today, Seymour’s Bionic Boot can propel him forward at 25 miles per hour. “You really feel superhuman,” he says. Eventually, Seymour hopes to boost the speed to 40 miles per hour, perhaps by enhancing the boots’ springy heels with electrical actuators. That, he expects, will take a few more prototypes.
The latest facial recognition technology works in the dark
It's getting harder and harder to get away from the cameras these days, and now a new type of facial recognition system goes further than most: it uses infrared scanning technology to match the thermal heat signature of a person’s with a standard photograph of it.
