Washington, September 17: Babies as old as 12 to 18 months not only observe what is going on around them, but also use their own visual self-experience to judge what other people can and cannot see, according to a new study.

"This research shows how infants are using their own experiences to understand the inner lives of other people," said Andrew Meltzoff, co-director of the University of Washington's Institute for Learning and Brain Sciences.

Washington, September 17: The discovery of ultra-efficient devices for drug delivery inside the body may have come a step closer to reality, with an India-origin University of Illinois researcher announcing the discovery of the physical mechanism behind the rapid transport of water in carbon nanotubes.

Narayana R. Aluru, a Willett Faculty Scholar and a professor of mechanical science and engineering, says that this discovery may also be beneficial for water purification, and nano-manufacturing.

"Extraordinarily fast transport of water in carbon nanotubes has generally been attributed to the smoothness of the nanotube walls and their hydrophobic, or water-hating surfaces," he said.

Washington, September 17: NASA’s Hubble Space Telescope has captured a rare alignment between two spiral galaxies, with images showing the outer rim of a small, foreground galaxy silhouetted in front of a larger background galaxy.

Skeletal tentacles of dust can be seen extending beyond the small galaxy’s disk of starlight.

Such outer dark dusty structures, which appear to be devoid of stars, like barren branches, are rarely so visible in a galaxy because there is usually nothing behind them to illuminate them.

Washington  - President George W Bush on Tuesday added Bolivia to a drugs blacklist after concluding the South American country has failed to cooperate in stemming the production and trafficking of illegal narcotics.

Bolivia joins Venezuela and Myanmar - also known as Burma - for failing to meet international obligations to curb drug trafficking, Bush said in a statement released by the White House.

Washington  - The United States on Tuesday welcomed the power sharing arrangement worked out between Zimbabwean President Robert Mugabe and opposition leader Morgan Tsvangirai and Washington expects the deal to be fully carried out by both sides.

The deal called for Mugabe to end his 28-year monopoly on power by naming Tsvangirai, the leader of the Movement for Democratic Change (MDC) as prime minister and divide cabinet posts evenly between the MDC and Mugabe's Zanu-PF party.

Washington  - The US Federal Reserve kept interest rates unchanged on Tuesday, citing both growth and inflation risks to the US economy amid an ongoing financial crisis in the country.

In a unanimous decision, the US central bank's federal funds rate was left at 2 per cent, despite some expectation that the week's financial turmoil might lead to a cut in the benchmark rate.

Wall Street stocks on Monday posted their worst losses since the September 2001 terrorist attacks, but had recovered slightly Tuesday afternoon.
