The court ruled that Myriad Genetics, which sells expensive tests for the genetic markers for cancer, could not claim patents on the DNA it identified in the 1990s to develop the tests.

Mysteries of myopia may soon become clear

A study aims to find genes that make us short-sighted and may reveal why so many people of Asian descent are affected. Photo: Dickson Lee

Two professors are hoping to discover why Asians are nearly three times more likely to be short-sighted than Westerners. They are taking part in a global study which has revealed that both groups share similar myopic-related genes. And they say the data will lead towards the development of genetic tests for short-sightedness, clinically known as myopia.

Video: Mutant cockroaches develop mechanism to evade sugar traps

The head of a male German cockroach. The insect's taste hairs, which extend from its face, antennae and mouth, contain sweet and bitter detectors that help some cockroaches avoid traps baited with glucose. Photo: Handout

In an evolutionary twist, some German cockroaches have developed a genetic mechanism that makes sugar taste bitter – allowing them evade sugary bait set out to kill them.

Three medical leaps that could transform disease treatments

Graphic: SMP

More than once last year, researchers described leaps in medical science that were so breathtaking, and held so much potential for patients, that they immediately joined the list of fields to watch in the year ahead. In most cases, the work was, and is, at an early stage and its success far from certain. But some may go down in history for transforming how medicine is done.

How we live affects our descendants' genes, epigenetics shows

Is smoking a sin?

The First Commandment of the Bible states: "For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children to the third and fourth generations of those who hate me ... "

Should we be cursed because of the sins of our forefathers until the third and fourth generations?

Scientists rebuild genome of girl from 50,000 years ago

Scientists have rebuilt the entire genetic make-up of a girl who lived and died in a Siberian cave more than 50,000 years ago.

The young woman belonged to a long extinct group of humans called Denisovans, their existence known only from meagre fossil remains uncovered at the Denisova cave in the Altai mountains in 2008.
