New York, March 7 : The anxiety-relief effects of marijuana are well known but scientists have found for the first time, how the controlled use of the drug may help people in distress.
Sachin Patel, a professor of psychiatry and molecular physiology at Tennessee-based Vanderbilt University identified cannabinoid receptors in the brain through which marijuana exerts its effects.
The cannabinoid receptors are located in a key emotional hub in the brain involved in regulating anxiety and the flight-or-fight response.
"The discovery may help explain why marijuana users say they take the drug mainly to reduce anxiety," Patel said.

Washington, March 7 - A scientist has created a mathematical recipe for the simplest trick - the flat loop.
Dr Pierre-Thomas Brun, of EPFL in Switzerland, said that elastic threads are everywhere in daily lives - from hair and textile yarns to DNA and undersea broadband cables.
He said that all of these threads twist and coil according to the same equations as the cowboy's lasso.
Dr Brun said that the physics just boils down to a few simple rules, asserting that the about 70 per cent of rope should be used in the loop, the BBC reported.

Washington, March 7 : A piece of rock that found its way from Mars to a desert in northwest Africa may help reveal the history and evolution of Mars.
Researchers pinpoint Mojave Crater, a 55-kilometer-wide-basin on the planet's equator, as the origin of the so-called "shergottites" meteorites, a family that includes about 75 percent of the roughly 150 known Martian meteorites, Discovery News reported.
Knowing where the meteorites came from will help researchers find about the history and evolution of Mars.

Emotinent has developed the ' Sentiment Analysis' prototype app, which aims to tell Google Glass wearers what other people are feeling based on their facial expressions.
The company's CEO Ken Denman said that it was a breakthrough technology that allows companies to aggregate customer sentiment by processing facial expressions anonymously, which would be particularly applicable in retail, Cnet reports.

Researchers at the University of Pennsylvania are adapting patients' own immune systems to help them defend against HIV.
Millions of T-cells were taken out from the patient's blood and grown in the laboratory until the doctors had billions of cells, the BBC reported.
Researchers then edited the DNA inside the T-cells to give them the shielding mutation - known as CCR5-delta-32.

Researchers using NASA's Spitzer Space Telescope to study developing stars have had a hard time figuring out why the stars give off more infrared light than expected.
The planet-forming disks that circle the young stars are heated by starlight and glow with infrared light, but Spitzer detected additional infrared light coming from an unknown source.

Washington, March 7 : Scientists have shown that in certain circumstances a pool of dense particles normally circling Earth, deep inside the magnetosphere, can extend a long arm out to meet - and help block - incoming solar material.
Brian Walsh, a space scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said that the material that is usually much nearer Earth stacks up against the outer boundary of the magnetosphere, throttling the interaction there and stopping solar material from entering.
Walsh and his colleagues compared observations from the ground and in space during a solar storm on Jan. 17, 2013.
Washington, Mar 07 : Facebook's constant tweaking of its News Feed apparently doesn't help much, as the latest change is really just the old feed with bigger photos and different font .

The images were acquired by ESA's Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found.
The lava flows seen in this image come from Arsia Mons, the southernmost volcano in the Tharsis complex, which lies around 1000 km to the northwest of the region featured here.

Although fragile comet nuclei have been seen to fall apart as they approach the Sun, nothing like the breakup of this asteroid, P/2013 R3, has ever been observed before in the asteroid belt.
The crumbling asteroid was first noticed as an unusual, fuzzy-looking object on 15 September 2013 by the Catalina. Follow-up observations on 1 October with the Keck Telescope on Mauna Kea, Hawaii, revealed three co-moving bodies embedded in a dusty envelope that is nearly the diameter of Earth.
