The researchers in the US have created see-through (transparent) solar cells that can be used as windows on cars or buildings, even as they generate electricity. 

Solar cell technology, which earlier used to be really light weight was not efficient enough to covert large amount of Sun’s energy into electricity. 

Nevertheless, a technique was discovered through the study led by scientist John Rogers of the University of Illinois, under which super thin cells were created that, delivered excellent efficiency. 

Washington, Oct 8 : When it comes to leadership, ‘self-centered’ narcissists are the best bet – if the group is without a leader.

That’s the conclusion of a new study.

Narcissism is a trait in which people are self-centered, overconfident in their own abilities, exaggerate their talents and abilities, and lack empathy for others.

In three consecutive studies, researchers found that people who score high in narcissism tend to take control of leaderless groups.

Washington, Oct 8 : A research team in Denmark has found new data about thermoelectric materials that can be used to develop motors that are more fuel-efficient and for more environmentally friendly cooling methods in the future.

Researchers at the University of Arhus, Riso-DTU and the University of Copenhagen, in Denmark, found the data.

Thermoelectric materials can be assembled into units, which can transform the thermal difference to electrical energy or vice versa - electrical current to cooling.

An effective utilization requires however that the material supplies a high voltage and has good electrical, but low thermal conductivity.

Washington, Oct 8 : Researchers at the Hebrew University of Jerusalem have discovered how to not only boost the natural smell of flowers by up to 10 fold but also transfer different scents between plants.

The research team has found a way to genetically enhance the scent of flowers and implant a scent in those that don''t have one.

"Aroma is of major importance for defining the taste of food,” said Prof. Alexander Vainstein, who is heading the team at the Robert H. Smith Faculty of Agriculture, Food and Environment.

Washington, October 8: Google has come up with “Mail Goggles” that can prevent people from sending stupid e-mails, especially at particular hours when they are most likely to be inebriated and at risk of making a complete idiot of themselves.

Mail Goggles throw five maths problems up on the screen when a user presses the “send” button. The problems have to be solved within a limited period of time.

Being able to do so would cause the system to presume that the user’s mental state is sound enough to send appropriate mails.

Even if a person is very good at solving mathematical problems, there is an option to ramp up the difficulty of the questions.

Washington, Oct 8: Pakistan once again emerged as one of the focal points of the debate between Democratic and Republican presidential candidates, Barack Obama and John McCain. The two rivals had the second of their three debates yesterday.

Both stuck to their earlier stances regarding tackling terrorism in Pakistan, particularly along the Pak-Afghan border.
