Op-Ed: The patent gene debate: who owns your genes?

The Federal Court of Australia has rejected an appeal of a ruling that allows companies to patent isolated human genes. This reignites the debate: who owns your genes - you or the company that extracts them?

Scientists identify gene responsible for jet lag

Research from the Salk Institute for Biological Sciences has pin-pointed the gene responsible for sleep and wake cycles, and could explain the reason why many folk find it difficult to adjust their sleep cycles when flying between time zones.

Mother’s diet can influence obesity in her young

Ramat Gan - By studying rats, researchers have unearthed an epigenetic link between a mother's diet and an offspring's risk of future obesity. This link relates to the blocked expression of a gene which goes onto trigger overeating.

New findings into an alcohol dependence gene

Scientists have linked a gene, already identified with alcohol dependence, with a neurotransmitter involved in anxiety and relaxation.

How genes tune the internal body clock

The human body clocks are regulated by a type of molecule known as long non-coding RNA, according to new research. Understanding this promises new insights into human health.

Genetic recipe allows lizards to re-grow their tails

Scientists have discovered the genetic “recipe” for lizard tail regeneration. This comes come down to using genetic ingredients in just the right mixture and amounts.

Fighting malaria by targeting genes

A new approach to preventing malaria by knocking out parasite's genes has been proposed. Biological engineers have demonstrated that a new genome-editing technique can disrupt a single parasite gene with a success rate of up to 100 percent.

Gene treatment for rare blood disorder

The blood disorder β-thalassemia is caused by a mutation in the HBB gene, which results in a severe hemoglobin deficiency. Researchers have successfully corrected the mutation in human induced stem cells.

Genetic engineering increases tomato yields

Enhancing the expression of a single gene in tomatoes seemingly improves the plant’s ability to withstand light and increases yields.

New autism genetic link revealed

In a new study, researchers determine that heritability outweighs non-genetic risk factors when it comes to the developmental disorder.

Genetic causes of schizophrenia are 'considerable'

The number of known genetic variants linked with schizophrenia has more than tripled, following a massive genome-wide association study.

Elephants are the greatest 'sniffers' on the planet

African elephants have the largest number of olfactory receptor genes known in mammals, nearly twice as many as dogs have, and five times more than humans.

Is there a genetics of 'friendship'?

A new study suggests that people tend to choose friends who share their genes. The inference is that humans tend to associate with other people who are very similar to themselves. Not all biologists agree.

Is intelligence inheritable?

Atlanta - The inheritance of intelligence has proved to be a controversial subject over many decades, and one fused with the nature-nurture debate. To add to the mix, some researchers have said that chimpanzees inherit general intelligence from their parents.

Not such a bitter taste for Vampire bats

Wuhan - Vampire bats exist on a diet mainly made up of blood. Due to this, the flying mammals have largely lost the ability to taste bitter flavors, according to a new study.

Genetic diversity high in Mexico

Mexico - A new genomic survey of Mexicans has revealed a range of gene diversity throughout North America’s southernmost land. The Mexican people studied showed as much genetic distance between them as individuals from different continents.

Companies in lawsuit over genetic tests

Tech company Myriad Genetics, a company behind tests for the cancer-associated mutations, is suing another competitor for patent infringement.

Mutation might reduce heart disease

New York - Genetic variants (mutations) that cripple a particular type of protein have been linked with a lower risk of heart attack and stroke.

KITLG gene regulates hair color

Stamford - A science team have pinpointed a gene enhancer that contributes to blond locks in humans. To have brown hair is more common; whereas to have blond hair is a form of gene mutation.

Gene within a gene contributes to aggressive leukemia

A small gene that is embedded in a larger gene plays a role in promoting acute myeloid leukemia, according to a new study. The research also identified a drug that inhibits expression of the smaller gene.

Link between Down syndrome and leukemia found

A link between people with Down syndrome and people at a heightened risk of developing leukemia during childhood has been uncovered through a new study harnessing advanced medical testing.

Should the U.S. prohibit reproductive cloning? Special

Researchers have produced stem cell lines using somatic cell nuclear transfer (SCNT) from cells, making human reproductive cloning more technically feasible. Is this a good idea?

Gene clue opens paths to treat child brain cancer

Paris - Genetic mutations found in brain tumours in children have opened up intriguing avenues to tackle this lethal form of cancer, researchers said on Sunday.

Removal of fat gene may slow down aging

A single gene appears to play a key role in coordinating the immune system and metabolism. Research suggests that deleting the gene in mice reduces body fat and extends lifespan.

Why some breast cancer treatments fail

Scientists have found why a type of breast cancer therapy that blocks estrogen synthesis to activate cancer-killing genes sometimes loses its effectiveness. This is because the cancer takes over patient's tumor and re-writes the DNA.

The first comprehensive atlas of human gene expression

Tokyo - A large international consortium has released the first comprehensive map of gene activity across the human body. It is hoped the findings can help to combat genetic diseases.

Breast cancer gene linked to brain development

The breast cancer-associated gene BRCA1 appears to play a protective role in neural stem cells, a new mouse study has found.

New gene linked to heart attack risk

Detroit - A previously unrecognized gene variation that makes humans have healthier blood lipid levels and reduced risk of heart attacks has been found by researchers.

Microbes and genes can affect cancer

Research suggests that the genes of certain bacteria, when they interact with the cells inside a person’s stomach, can influence whether the person is likely to develop cancer or not.

New clues to stopping breast cancer

A new study suggests that a protein has a significant effect on the risk that breast cancer will spread. The study also showed that lowering the protein’s level could reduce chances for the disease to extend beyond the initial tumor.
