Flying Car Flying car races are no longer just reserved for computer games and science fiction movies, now they are hitting the real world. The organisers behind the world’s first motorsport series for flying electric cars,  Airspeeder , say the races are expected to take place in 2020, with a view to scheduling a full Grand Prix championship season soon after. Meanwhile, they have "bold ambitions to accelerate a revolution in sustainable transport," the founder of the race, Matt Pearson told Euronews Living. Once restrictions related to the coronavirus crisis are lifted, the Speeders (flying electric cars) will be further tested - they have already undergone successful unmanned tests using a remote control. A team of test pilots recruited from the US Air Force and Martin Aviation are in charge of the MK3 prototype, which is set to be trialled in the Mojave Desert, California. The Speeders can gain up to 200 kph at full speed and fly between 5-40 metres off the groun

       About Human Heart: A well developed specialized system to transport nutrients,gases and hormones within the body.' This system is known as circulatory system,namely blood , blood vessels and heart.                   Blood is a fluid connective tissue. Blood circulates and transport essential substances such as oxygen and nutrients to the cells all over the body. It composed of plasma and blood cells.There are three type of blood cells or corpuscles. They are red blood cells(RBCs) or erythrocytes,white blood cells (WBCs)or leukocytes, and blood platelets or thrombocytes. Diagram of Heart. The  heart  is a  muscular   organ  in most animals, which pumps  blood  through the  blood vessels  of the  circulatory system . [1]  Blood provides the body with  oxygen  and  nutrients , as well as assisting in the removal of  metabolic wastes . [2]  In humans, the heart is located between the lungs, in the  middle compartment  of the  chest . [3] In humans, other

"Rerouting a fraction of flights may reduce the sooty clouds’ environmental impact" High-flying jets often create long white lines across the sky. Called contrails, those narrow clouds can vanish within minutes or last for days. Like other clouds, long-lasting contrails can trap heat in the atmosphere. Scientists have found in the last year or two that these contrails can boost the warming of Earth’s atmosphere. But it may be fairly simple to lower that contribution: Just make a few planes fly higher throughout much of their route. Engineers in England recently studied flights and contrails in a high-traffic part of the sky above Japan. Along the way, they turned up a surprising pattern. About 80 percent of the warming from contrails came from just 2 percent of the flights. “The fact that it’s such a small [number] of flights means we think it’s a feasible solution,” says engineer Marc Stettler. He led the study and works at Imperial College London. Sending just
