Washington, March 18: A mechanical engineer of Indian origin is developing techniques that will help improve gas mileage by reducing the drag of vehicles.

Drag is an aerodynamic force that is the result of resistance a body encounters when it moves in a liquid or gaseous medium, such as air.

Reduction in drag means less fuel would be required to overcome the fluid resistance encountered by the moving vehicle.

Ramesh K. Agarwal, the William Palm Professor of Engineering at Washington University in St. Louis, has successfully demonstrated that the drag of airplane wings and cars/trucks can be reduced by employing the active flow control (AFC) technology.

London, March 18 : Scientists have spotted

Washington, March 18: A new crewmate aboard the International Space Station (ISS) is testing a new line of clothing that is literally threaded with anti-bacterial and deodorizing materials, making it ‘odor free’.

According to a report in Discovery News, the crewmate in question is Koichi Wakata, a Japanese astronaut, who is serving as a station flight engineer on the ISS.

Wakata is testing a new line of clothing developed for the Japan Aerospace Exploration Agency that is made with anti-bacterial and deodorizing materials.

Washington, March 18: Marine scientists have discovered a new species of jellyfish near the waters of Tasmania, which has a “rainbow glow”.

According to a report in National Geographic News, Jellyfish expert Lisa Gershwin caught the unnamed species in early March while swimming near a jetty off the Australian island of Tasmania with a “phototank” — a small aquarium that makes it easy to photograph sea life.

The jellyfish does not emit its own light, as bioluminescent creatures do.

Washington, March 18 : Scientists at the University of California - Los Angeles (UCLA) say that a new study lends more force to the suggestion that intelligence is largely inherited.

The researchers used a new type of brain-imaging scanner to show that intelligence is strongly influenced by the quality of the brain''s axons, or wiring that sends signals throughout the brain.

Given that the integrity of the brain''s wiring is influenced by genes, the researchers suggest that the inheritance of genes play a far greater role in intelligence than was previously thought.

Washington, March 18 : A new analysis by a group of mission scientists has determined that salty, liquid water has been detected on a leg of the Mars Phoenix Lander and therefore could be present at other locations on the Red Planet.

This is the first time liquid water has been detected and photographed outside the Earth.
