Genetic history of modern Europeans a tangled tale: Research

The genetic origins of modern Europeans may be more complicated that previously thought.

New genetic risk markers identified for pancreatic cancer

A new discovery has been made with help of large DNA analysis of humans, which says that there are several genetic markers to identify pancreatic cancer.

`Common` rare genetic factors responsible for developing autism: Study

A recent study has proved that 60 percent of the risk for developing autism is caused by genetics and a major portion of that risk is caused by inherited variant genes that are common in the population and present in individuals without the disorder.

Gene that mediates ageing identified

In what could point towards the possibility of one day using therapeutics to combat ageing, researchers have found in animal models that a single gene plays a surprising role in ageing that can be detected early in development.

Genetic `barcode` to identify origin of malaria

Containing malaria could be a lot more convenient as researchers have now designed a genetic barcode of malaria parasite, which can be used to identify the geographic origin of the parasite from a blood sample and monitor its spread.

Genetically-modified mosquitoes could help wipe out malaria

Scientists have successfully modified mosquitoes to produce sperm that will only create male offspring, pioneering a fresh approach to eradicating malaria.

Subtle changes in DNA determine our hair colour

Researchers have claimed that a molecule critical to stem cell function plays a major role in determining human hair color.

Learn why homo sapiens survived when others could not

Only we, the Homo sapiens, who lived side by side with Neanderthals and Denisovans of Siberia survived and a study offers fresh insights into what gave the modern man the advantage over other extinct humans.

Down`s chromosome cause genome-wide disruption

The extra copy of Chromosome 21 that causes Down`s syndrome throws a spanner into the workings of all the other chromosomes as well, said a study published Wednesday that surprised its authors.

Age-related decline in sleep quality could be reversed

Researchers have suggested that age-related sleep decline can be prevented and might even be reversible.

`Carb breakdown` gene key player in obesity

Scientists have discovered that people with fewer copies of a gene coding for a carb-digesting enzyme may be at higher risk of obesity.

Men four times likelier than women to suffer from autism

Researchers have revealed that that it takes more mutations to trigger autism in women than in men, which may explain why men are four times more likely to have the disorder.

Self-rated physical fitness in midlife may reveal individuals` risk of dementia

A new collaborative study from Finland has found that a simple question about self-rated physical fitness in midlife may reveal individuals who are at an increased risk of developing dementia.

Genetics linked to violent media consumption in children

A new study has found that a specific variation of the serotonin-transporter gene was linked to children who engaged in increased viewing of violent TV and playing of violent video games.

Dogs suffer from OCD too

A new study has found that certain dog breeds such as German shepherds and Doberman pinschers are prone to high rates of obsessive-compulsive disorder(OCD.

Genetic function that could pave way for cancer therapies discovered

A team of researchers has discovered a genetic function that helps one of the most important "tumour suppressor" genes to do its job and prevent cancer.

New drug breakthrough brings osteoporosis cure closer to reality

A team of scientists has discovered a new drug which appears to be a potent stimulator of new bone growth, thus leading to new treatments for osteoporosis and other diseases that occur when the body doesn`t make enough bone.

33 new genes behind onset of cancer uncovered

A research team has found many new cancer genes - expanding the list of known genes tied to these cancers by 25 percent.

20% of women with ovarian cancer inherit predisposition to disease

A new research at Washington University School of Medicine in St. Louis has estimated that one in five women with ovarian cancer inherit genetic mutations that increase the risk of the disease.

Genetic causes of schizophrenia are multiple

Schizophrenia is caused by a large number of rare genetic mutations rather than a few, easily-identifiable faulty genes, said scientists who compiled the world`s largest database on the debilitating disorder.
