Washington: NASA is planning to send a nuclear-powered submarine to explore one of the methane seas located on Saturn's moon Titan.

The single-tonne concept robot submarine is equipped with a seafloor camera and sampling system.

The submarine could fit into a space plane such as Boeing's X-37, which was recently used for a classified Air Force mission.

The plane could land on Kraken Mare, the largest known body of liquid on Titan that consists mostly of liquid methane, or possibly drop the submarine using a parachute, 'ibtimes. Com' reported.

"The vehicle would use conventional propulsors to yaw around, using a sun sensor to determine the initial azimuth to Earth and begin communication using a terrestrial radio as a more precise reference," NASA said.

London: Scientists have found that reducing the size of tiny hair like structures on stem cells stops them from turning into fat cells, a discovery that may allow for new treatments to prevent obesity.

The research, conducted at Queen Mary University of London (QMUL), found that a slight regulation in the length of primary cilia, small hair-like projections found on most cells, prevented the production of fat cells from human stem cells taken from adult bone marrow.

Part of the process by which calories are turned into fat involves adipogenesis, the differentiation of stem cells into fat cells, researchers said.

The study showed that during this process of adipogenesis, the length of primary cilia increases associated with movement of specific proteins onto the cilia.

London: Mysterious cloud-like plumes seen reaching high above the surface of Mars have puzzled scientists studying the atmosphere of the Red Planet.

On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet.

The plumes were seen rising to altitudes of over 250 km above the same region of Mars on both occasions. By comparison, similar features seen in the past have not exceeded 100 km.

"At about 250 km, the division between the atmosphere and outer space is very thin, so the reported plumes are extremely unexpected," said Agustin Sanchez-Lavega of the Universidad del Pais Vasco in Spain, lead author of the paper published in the journal Nature.

New Delhi: Betting big on new technologies to boost growth, country's second-largest software services firm Infosys will acquire US-based automation technology company Panaya for USD 200 million (over Rs 1,200 crore).

The all-cash deal is the second-largest acquisition for the Bangalore-based firm, after Swiss consulting company Lodestone, which it bought for about USD 350 million (Rs 1,932 crore) in 2012.

The move comes as part of Infosys' 'Renew and New' strategy to enhance competitiveness and productivity of current service lines by leveraging automation, innovation and artificial intelligence, Infosys said in a statement.
