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: Astronomers have found evidence that high-speed collisions between large galaxies can turn off the process of star formation.

The evidence was found in the form of a deep new image of the Virgo cluster, which revealed monumental tendrils of ionized hydrogen gas 400,000 light-years long connecting the elliptical galaxy M86 and the disturbed spiral galaxy NGC
4438.

Taken with the wide-field Mosaic imager on the National Science Foundation’s Mayall 4-meter telescope at Kitt Peak National Observatory, the image and related spectroscopic measurements of the filament provide striking evidence of a previously unsuspected high-speed collision between the two galaxies.

Washington, Oct 8: Scientists have suggested that mass extinctions have happened in the Earth’s history because the planet got “sick”.

It is believed that asteroids are the reason behind cataclysmic events leading to mass die-off of life on the planet.

But, many geologists suggest that an asteroid is the prime suspect only in the most recent of five mass extinctions, the catastrophe 65 million years ago that wiped out the dinosaurs.

“The other four have not been resolvable to a rock falling out of the sky,” Bottjer said.

Washington, October 8: A team of Canadian psychologists has created a personality inventory that can help detect people who can excel in academic and creative domains, even when respondents are trying hard to fake their answers.

The researchers say that their inventory can offer a better tool than the traditional personality questionnaires that have been plagued by the problem of biased responding.

"It''s very common for people to try and make themselves look better than they actually are on these questionnaires, especially if they know they are being evaluated," said Jordan B. Peterson, psychology professor at the University of Toronto.

Washington, Oct. 7: Democratic presidential candidate Barack Obama has said that he has no knowledge of William Ayers' terrorist activities during the violent Weather Underground movement.

"When he went (in 1995) he certainly didn't know the history," chief Obama strategist David Axelrod told CNN.

Washington, Oct 7: A tiny boulder sized asteroid, discovered at an Arizona observatory, is predicted to enter the Earth’s atmosphere tonight, and burn up before reaching the ground.

There is no danger to people or property since the asteroid will not reach the ground. It is between 3 and 15 feet (1-5 m) in diameter and will burn up in the upper atmosphere, well above aircraft heights.

A brilliant fireball will be visible as a result.
