Russia's prototype fifth-generation Sukhoi T-50 fighter jet has carried out its first long-range flight. The flight was carried out during the transfer from a manufacturing plant in the far east to an assigned airfield near Moscow, deputy Prime Minister Dmitry Rogozin said. "It is a serious breakthrough! The plane flew 7,000 km, making two landings, in Abakan and Chelyabinsk, on the way to the Russian capital," Rogozin, who oversees the defence industry, wrote in Twitter.

By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers have found that greenhouse gas concentrations similar to the present are systematically associated with sea levels at least nine metres above current levels.

India achieved partial success while test firing its first indigenous cruise missile 'Nirbhay' as it's lift-off was successful but the flight was terminated halfway. However, the scientists at Defence Research and Development Organisation (DRDO), which has tested this missile at Sea test range Chandipur, Odisha said that they have not been able to achieve complete range capability, but the mission objectives have been met.

Prime Minister Manmohan Singh Thursday called for a scientific approach to dealing with contentious issues such as genetically modified food and nuclear energy. Speaking at the Indian Science Congress centenary session here, he said "complex issues" including those of "genetically modified food or nuclear energy or exploration of outer space cannot be settled by faith, emotion and fear but by structured debate, analysis and enlightenment".

A new strain of norovirus that could cause a severe epidemic of acute gastroenteritis this winter has surfaced, warn researchers.

A NASA spacecraft is providing new evidence that a Martian crater once may have held groundwater-fed lake. The new information comes from researchers analyzing spectrometer data from NASA's Mars Reconnaissance Orbiter (MRO), which looked down on the floor of McLaughlin Crater. The Martian crater is 57 miles (92 KM) in diameter & 1.4 miles (2.2 KM) deep. McLaughlin's depth apparently once allowed underground water, which otherwise would have stayed hidden, to flow into the crater's interior.

In a first, Prime Minister Manmohan Singh Thursday chaired a session on science for shaping the future of India at the Science Congress here.
