London, Oct 31: A new research has pinpointed some of the genetic changes that allowed vampire bats to evolve to subsist on a diet of pure blood.

According to a report in New Scientist, key among those changes is a knack for keeping their meals from coagulating, which they do with the help of a gene found in other animals – plasminogen activator.

In humans, the gene protects against heart attack by producing proteins that bust up blood clots and clear vessels.

Previous research had shown that vampire bats activate the gene in their saliva, too.

Washington, Oct 31: A new research has determined that ancient meteorites that are among the oldest rocks ever found, still contain magnetic records about the very early history of planets.

MIT planetary scientist Benjamin P. Weiss did the research.

Weiss and his five co-authors examined pieces of three meteorites called angrites, which are among the most ancient rocks known.

The analysis showed that surprisingly, during the formation of the solar system, when dust and rubble in a disk around the sun collided and stuck together to form ever-larger rocks and eventually the planets we know today, even objects much smaller than planets — just
160 kilometers across or so — were large enough to melt almost completely.

Washington, Oct 31: Former President Bill Clinton said at a rally that Democratic presidential nominee Barack Obama during the financial meltdown acted like “what a president does in a crisis.”

“He said, ‘Tell me what the right thing to do is. What’s the right thing for America? Don’t tell me what’s popular. You tell me what’s right – I’ll figure out how to sell it,’” Clinton said.

Clinton said when the crisis broke, Obama called his own advisers as well as those of the former two-term president, Bill Clinton, Warren Buffet and others.

Washington, Oct 31: Risk of heart attack increases with adjusting clocks in summers while turning the clock back during autumn reduces the danger slightly, shows a new Swedish study.

Scientists at Karolinska Institutet have examined how the incidence of myocardial infarction in Sweden has changed with the summer and winter clock-shifts since 1987.

The researchers found that adjusting the clocks to summertime on the last Sunday in March increases the risk of myocardial infarction in the following week, because of a lack of sleep during the time.
