San Diego: Dr John Kelsoe has spent his career trying to identify the biological roots of bipolar disorder.

A genetic circuit in HIV that decides whether it switches on or stays dormant could hold the key to anti-HIV therapy, according to a new study.

Overeating disrupts entire networks of genes in the body, causing not only obesity, but diabetes and heart disease, in ways that may be possible to predict, researchers reported on Sunday.

Washington: Tiny skeletons found in the caves of the Pacific islands of Palau undercut the theory that similar remains found in Indonesia might be a unique new species of humans, researchers reported

Washington: China's current carbon emission levels have set alarm bells ringing for environmentalists as they are likely to upset global greenhouse stabilisation efforts.

New York: Scientists claim to have built a supercomputer which has confirmed the Standard Model theory of the Universe to even greater precision than before. The 30-year-old theory encapsulates understanding of all the material that makes up the universe. However, it excludes the force of gravity which is the missing piece in the jigsaw that would extend the Model into a complete theory. The project's enormously complex calculations relate to the behaviour of tiny particles found in the nuclei of atoms, known as quarks. In order to carry out these calculations, the researchers first designed and built a supercomputer that was among the fastest in the world, capable of tens of trillions of calculations per second. The computations themselves have taken a further three years to complete. The results have revealed that the Standard Model's claim to be the best theory invented holds firm. It raises the stakes for the riddle to be solved by experiments to be conducted later this year. "Modern supercomputers and improved theoretical techniques are allowing us to explore the limits of the Standard Model to an unprecedented precision. "The next stage will be to combine such computations with new experimental results expected from the Large Hadron Collider to unravel the next level of fundamental physics,' lead scientist professor Chris Sachrajda of the University of Southampton was quoted by the ScienceDaily as saying. Added co-researcher professor Richard Kenway: "Although the Standard Model has been a fantastic success, there were one or two dark corners where experiments had been inconclusive as vital calculations were not accurate enough. We shone a light on one of these, but nothing was lurking there.' PTI

Pranab Aims To Take IAEA Safeguards Pact To US The ides of March may be India's internal deadline for completing the IAEA safeguards agreement on its civilian nuclear facilities. This has reportedly been decided by the government, after the MEA-DAE team returned from Vienna on Sunday with what appears to be the final draft of the agreement. The government's legal brains will now go through the agreement to see if India can "live with' it. This exercise, sources said, should be completed by the middle of this month. The completed Indian safeguards agreement is expected to dovetail into foreign minister Pranab Mukherjee's maiden visit (as foreign minister) to Washington on March 23-25, where he is expected to present this to his counterpart Condoleezza Rice. Politically, sources said, it would make sense for Mukherjee to go to Washington with a concrete document in hand, rather than open himself up to a host of diplomatic harangue. Sources indicated that the crucial UPA-Left meeting will probably be scheduled after his return and after the CPM's party congress scheduled for March 29. This remains the imponderable because it's not yet clear whether the government will take the agreement beyond the Left's veto
