Washington, April 21 : Scientists at the Cambridge University, UK, have discovered that freshwater algae can form stable groupings in which they dance around each other, resembling forms like waltz and minuet.

The researchers studied the multicellular organism Volvox, which consists of approximately 1,000 cells arranged on the surface of a spherical matrix about half a millimetre in diameter.

Washington, April 21 : Scientists at Harvard University, US, have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming.

The finding provides more evidence of the intertwining of severe weather and global warming by demonstrating a mechanism by which storms could drive climate change.

Many scientists now believe that global warming, in turn, is likely to increase the severity of tropical cyclones.

Washington, April 20 : A new study has determined that a widely discussed "atmospheric engineering" scheme intended to combat global warming could have unanticipated consequences in reducing the effectiveness of certain kinds of solar power around the Earth.

In the study, the National Oceanographic and Atmospheric Administration's Daniel M. Murphy examines a proposal to minimize climate change by enhancing the stratospheric aerosol layer, which reduces sunlight to Earth by scattering it to outer space.

London, April 20 : Marc Ona Essangui, a campaigner who was jailed during his battle to save the rainforest in Gabon, Africa, has received a top international award, known as the `Green Nobel'.

According to a report by BBC News, Ona was honoured for his fight to stop what he describes as a destructive mining project in the Ivindo National Park.

He is one of seven people from six continental regions to be awarded an equal share of the 900,000 dollars (600,000 pounds) 2009 Goldman Environmental Prize.

Washington, Apr 20 : Michigan scientists have unravelled the mystery behind the much hyped healing power of the main ingredient in turmeric, a spice revered in India as `holy powder.'

Turmeric has been used for centuries in folk medicine to treat wounds, infections, and other health problems.

While many scientists have conducted research on its main ingredient-curcumin-no details had been revealed as to how it functions in the body, until now.
