Washington, Dec 13: Fossil experts have identified a new species of meat-eating dinosaur, which is larger than Tyrannosaurus Rex, from the remains found in North Africa.

The study, led by Steve Brusatte, a student at the University of Bristol in the United Kingdom, stated that the formerly unknown dinosaur, named as Carcharodontosaurus iguidensis, grew up to 45 feet long and used huge ‘steak knife’ teeth for slashing through prey.

"It was just a completely ferocious animal. The teeth of this guy were enormous. They were the size of bananas, but they were very thin teeth, " National Geographic quoted Brusatte, as saying.

The dinosaur's skull was about 5.5 feet long and was relatively lightweight given the animal's size.

London, Dec 13: A team of researchers including an Indian scientist have identified the chemical switch that facilitates the genetic mechanism controlling human body’s circadian rhythms or the internal body clock.

The findings by the researchers at University of California, Irvine, have discovered the precise information regarding the body’s circadian rhythms till date and this would specifically lead to a new pharmaceutical approach for sleep disorder treatments.

The study was authored by Paolo Sassone-Corsi, distinguished Professor and Chair of Pharmacology and Saurabh Sahar, Department of Pharmacology, School of Medicine, UC.

It was discovered that the genes controlling circadian rhythms were stimulated by a single amino acid.
