London, April 27 : In a new research that involved the use of computer simulations, scientists have shown that raindrops actually splash just a few microseconds before hitting the ground.

A liquid drop hitting a surface often flattens into a thin sheet that then bounces to form a crown shape.

Previous experiments have suggested the surrounding air plays a role: a droplet doesn't splash so easily when the air pressure is low, instead spreading out into a thin pancake.

London, Apr 27 : In a new study on stem cells, scientists at Gladstone Institute of Cardiovascular Disease have discovered a combination of genes, which can play a vital role in repairing damaged heart.

The research team led by Dr Benoit Bruneau has found that the combination of three genes can turn nonmuscle cells into beating heart cells.

"The heart has very little regenerative capacity after it has been damaged," said Nature magazine quoted Bruneau as saying.

Washington, April 27 : Scientists have discovered a dinosaur tooth along what's now the Kakanaut River of northeastern Russia, a find that shows dinos once lived above the Arctic Circle.

Scientists say the dinosaurs became extinct 65 million years ago when a big meteor crash set off volcanoes galore, with dust and smoke filling up the air.

One theory holds that cold, brought on by the Sun's concealment, is what did them in, but a team of paleontologists led by Pascal Godefroit, of the Royal Belgian Institute of Natural Sciences in Brussels, argues otherwise.

Washington, Apr 27 : New York scientists have found that cutaneous application of nanoparticles, could offer a new means of delivering drugs to treat erectile dysfunction (ED).

The findings have revealed that topical treatments for ED could provide localized therapeutic results with the benefit of lower dosage and the avoidance of adverse side effects due to systemic absorption.

For the study, the researchers investigated a novel hybrid hydrogel/glass nanoparticle platform.

Hamburg  - Using 21st Century medical computer technology, German researchers have unveiled the "hidden face" below the surface facial features of the famed bust of 18th Dynasty Queen Nefertiti - dispelling once and for all nagging rumours that the bust might be a duplicate made at the orders of Adolf Hitler in the 1930s, and that the genuine bust was lost in the chaos following World War II.

London, Apr 26 : A team of researchers has claimed to have solved the mystery that intrigued the science world for decades: Whether or not fish feel pain?

And, the answer is yes. Just like humans, goldfish feel pain too.

Whilst the marine creatures can be seen to react to a jab or blow, experts have disagreed over whether the reaction indicates a sensation of pain, or is little more than a basic reflex.

Therefore, researchers, from Norway and the US, embarked on a study to set the record straight.
