Life on Earth began on land, not sea: Scientists

The findings pushes back the time for the emergence of microbial life on Earth by 580 million years.

Scientists discover mechanism that may prevent death of cells

Scientists discover mechanism that may prevent death of cells

The UK's University of Sheffield scientists identified that tuning up the activity pathway of the DNA's natural repair toolkit ? which normally helps to restore breakages in genetic material - could help to prevent the death of nerve cells which trigger neurological diseases.

The well-functioning artificial heart is a real necessity, researchers said.

New robots can follow spoken instructions

New robots can follow spoken instructions

Scientists, including those of Indian origin, have developed robots that can follow spoken instructions, an advance that may make it easier for people to interact with automated machines at home and workplaces.

Excess calcium behind dangerous hospital infection

The study showed that increased levels of calcium in the gut, because of certain medications or supplements, triggers Clostridium difficile (C. diff) -- a bacterium that chiefly affects older patients living in nursing homes, or those who have been confined to a hospital environment for a long time.

This eight-legged ‘freak’ animal will survive on Earth until Sun dies

The tardigrade is considered the world’s toughest animal, despite its diminutive size which is under a millimetre (0.04 inches).

Scientists encode, replay movie encoded in bacterial DNA

Harvard scientists have encoded and played back a primitive movie in the DNA of living bacterial cells, an advance that may lead to "molecular recorders" which will help observe brain cells in real time.

A human enzyme that can unravel protein aggregates the hallmark of a number of neurodegenerative diseases has been identified by scientists.

Scientists discover rare blue-coloured parrot species in Mexico

Scientists discover rare blue-coloured parrot species in Mexico

The parrot, referred to as the Blue-winged Amazon, occupies a similar area in the Yucatan Peninsula as the Yucatan Amazon and the White-fronted Amazon but it does not hybridise with them, said researchers from the University of Florida in the US.

Scientists give clue on how to block bad memories

Scientists give clue on how to block bad memories

Brains create long-term memories by increasing the strength of connections between neurons and maintaining those connections over time.
