How aggression can change your brain

 Aggression can lead to generation of new nerve cells in the brain and also change the activity of existing cells, new research has found.

How vitamin A can reduce scarring in blood vessels

 A team of US researchers has developed a new biodegradable material with built-in vitamin A which has been shown to reduce scarring in blood vessels.

Decoded: What 'silences' X chromosome in girls

Nearly every girl and woman on Earth carries two X chromosomes in each of her cells -- but one of them does (mostly) nothing. Do you know why?

Now, novel way to make cleaner fuel cells

An international group of scientists from Russia, France and Germany has developed a novel method to make cleaner fuel cells.

Smokers, e- cigarettes can harm human cells

If you were thinking that electronic cigarettes are harmful for your health, then a recent study reveals that they can damage cells in ways that could lead to cancer and this damage can occur even with nicotine-free versions of the product.

Cellular sensor helps plants find light: Study

Plants wage wars to absorb sunlight and outgrow each other by using their cellular sensors that can set off an internal alarm when threatened by the shade of other plants, scientists have found. If a plant is shaded by another, it becomes cut off from essential sunlight it needs to survive.

Is Ebola virus one-up against bats?

Ebola virus and bats have been waging a molecular battle for survival that may have started at least 25 million years ago, revealed a new study led by an Indian-origin scientist.

Umbilical cells help eye's neurons connect

 Cells isolated from human umbilical cord tissue produce molecules that help retinal neurons from the eyes of rats grow, connect and survive, a new study reveals.

Japanese scientists discover HIV inhibiting protein

TokyoJapanese scientists have discovered a protein, found in humans, that has inhibitory effects on the human immuno-deficiency virus (HIV), the media reported on Wednesday.

Research reveals how cells repair DNA damage

 Danish researchers have discovered a previously unknown function in histones -- responsible for packaging the DNA into structural units -- that will help improve understanding of how cells protect and repair DNA damage.

Humans may one day regrow their own teeth

 Humans may be able to regrow their own teeth in the same way as a cichlid fish in Malawi lake, according to a new research.

High cholesterol may cause tendon abnormalities

 High levels of cholesterol are linked to a heightened risk of tendon abnormalities and pain, reveals a pooled analysis of the available evidence.

Researchers develop new method to trap cancer cells

An international team has discovered a new way to potentially "fence in" a tumour and help stop cancer cells spreading, according to a study released on Thursday by Cancer Research UK.

Now, stopping spread of cancer comes closer to reality

Scientists have discovered a new way to potentially trap cancer cells before they spread.

Viruses are actually living entities

Viruses are actually living entities

Viruses are living entities that share a long evolutionary history with cells, says a new study that traces viral evolution back to a time when neither viruses nor cells existed in the forms recognised today.

Tree of life shares common molecular tool kit

 In one of the largest and most detailed studies of animal molecular biology ever undertaken, researchers discovered the assembly instructions for nearly 1,000 protein complexes shared by most kinds of animals, revealing their deep evolutionary relationships.

Cells that re-generate liver without cancer risk

 Scientists have discovered new type of cells which are an important part of liver regeneration.

Here's what switches our sleep button on and off

Ever wondered how you went off to sleep and how you woke after sleep?

Genetically-modified yeast yields cheap painkillers

 Researchers from Stanford University have genetically engineered yeast to make painkilling medicines, a breakthrough that heralds a faster and potentially less expensive way to produce many different types of plant-based medicines.

Scientists identify source of liver stem cells

Scientists identify source of liver stem cells

Solving a long-standing mystery about the origin of new cells in the liver, scientists have identified stem cells in the gland that give rise to functional liver cells.
