DNA in the news

DNA carries traces of past events meaning poor lifestyle can affect future generations

Scientists now know that our DNA is being altered all the time by environment, lifestyle and traumatic events.

Genetic test proves President Harding DID father a love child with mistress who he would have sex with in a West Wing closet

 Pres.Harding+Nan Britton+Elizabeth Ann

Relatives of President Warren G Harding revealed to the New York Times on Wednesday that he did indeed father a daughter in 1919 with his longtime mistress Nan Britton, after receiving the results of a genetic test linking them to the son of the love child.
Rumors of Harding's infidelity became tabloid fodder in 1927, when Britton authored a tell-all on their secret relationship, revealing juicy facts like the fact that they used to have sex in a West Wing closet.  But Britton's claim that she bore Harding's one-and-only offspring was treated with heavy skepticism, as the president's family insisted that he had was sterile due to a childhood case of the mumps.

Smart people live longer: 95% of the link between intelligence and longevity 'is down to good genes'

Researchers analyzing data from twins found that 95 per cent of the link between intelligence and life expectancy is genetic.
They found that, the brighter twin tends to live longer and noted the pattern was much more pronounced in fraternal - non identical - twins, than identical pairs.  By looking at both fraternal twins - who only share half their twin's DNA - with identical twins, helps researchers distinguish between genetic effects and environmental factors, including housing, schooling and childhood nutrition.

Amazon, Google race to get your DNA into the cloud

Amazon.com Inc is in a race against Google Inc to store data on human DNA, seeking both bragging rights in helping scientists make new medical discoveries and market share in a business that may be worth $1 billion a year by 2018.

That growth is being propelled by, among other forces, the push for personalized medicine, which aims to base treatments on a patient's DNA profile. Making that a reality will require enormous quantities of data to reveal how particular genetic profiles respond to different treatments.  Already, universities and drug manufacturers are embarking on projects to sequence the genomes of hundreds of thousands of people. The human genome is the full complement of DNA, or genetic material, a copy of which is found in nearly every cell of the body.

Clients view Google and Amazon as doing a better job storing genomics data than they can do using their own computers, keeping it secure, controlling costs and allowing it to be easily shared.
