Innovations like 3-D printing have enabled scientists to make significant progress in manufacturing various bioengineered organs and tissues. However, the one organ that has been hard to replicate is the human heart. That’s because current technology is unable to create the network of tiny blood vessels that transport oxygen inside a tissue as dense as the human heart muscle.
Glen Claudette, a Professor of Biomedical Engineering at the Worcester Polytechnic Institute (WPI) in Worcester, Massachusetts, was pondering over this issue with graduate student Joshua Gershlak when they came up with a brilliant idea. Instead of trying to re-create the tiny veins, why not take advantage of the similar network present in leaves to deliver water and nutrients to plant cells?

When Michael Phelps announced his retirement at the 2016 Rio Olympics he really had no intention of swimming competitively again. However, that changed when the decorated athlete was approached by the Discovery Channel to help kick off Shark Week with a race against one of the world’s fastest and most efficient predators — a great white!
To prepare for the big event, Phelps, who has set 39 world records and garnered 28 Olympic medals, practiced by racing against a reef and a hammerhead shark – both computer generated, of course. While the swimmer’s time of 18.7 seconds was enough to beat the reef shark by 0.2 seconds, he fell behind the hammerhead, which completed the 50-meter distance in 15.1 seconds.

Flying cars have been in the works since 1946, when aeronautical engineer Ted Hall created two prototypes of the ConvAirCar. Unfortunately, a crash landing due to low fuel caused the hybrid vehicle’s manufacturer, Convair, to lose interest and shut down the venture within a year. While there have been numerous attempts since, none have gone beyond the experimental stage. That is about to change thanks to a slew of new and established companies that are determined to make this 70-year-old quest a reality.
On April 25, California-based start-up Kitty Hawk made headlines when it unveiled a video of its flying vehicle that will be available before the end of the year. The single-seater, propeller-powered Kitty Hawk Flyer is classified as an ultralight aircraft by the Federal Aviation Authority (FAA) and approved for recreational flying in “uncongested areas.” Though the jet-ski-like vehicle, which can only be flown over water, is not quite the futuristic flying commuter car one would have envisioned, Kitty Hawk says they have other models in the works.
