Scientists ‘edit’ DNA to correct adult genes and cure diseases

A genetic disease has been cured in living, adult animals for the first time using a revolutionary genome-editing technique that can make the smallest changes to the vast database of the DNA molecule with pinpoint accuracy. Scientists have used the genome-editing technology to cure adult laboratory mice of an inherited liver disease by correcting a single “letter” of the genetic alphabet which had been mutated in a vital gene involved

Nasa images suggest that Saturn is about to ‘give birth’ to a new moon

New images from Nasa ‘s Cassini-Huygens space probe suggest that Saturn may be in the process of forming a new moon, which has already been affectionately named by scientists as “Peggy”. The tiny, icy satellite has not been spotted directly, but a bulge in Saturn’s A Ring — the brightest and outermost ring — suggests that the new arrival could soon join Saturn’s already impressive family of 62 moons. “We

Supermoon shines brightly this weekend

A “supermoon” rises this weekend. The biggest and brightest full moon of the year graces the sky early Sunday as our celestial neighbor swings closer to Earth than usual. While the moon will appear 14 percent larger than normal, sky watchers won’t be able to notice the difference with the naked eye. Still, astronomers say it’s worth looking up and appreciating the cosmos. “It gets people out there looking at the

Russian scientists claim to have found woolly mammoth blood in preserved carcass

RUSSIAN scientists claim to have discovered blood in the carcass of a woolly mammoth, adding that the rare find could boost their chances of cloning the prehistoric animal. An expedition led by Russian scientists earlier this month uncovered the well-preserved carcass of a female mammoth on a remote island in the Arctic Ocean. Semyon Grigoryev, the head of the expedition, said the animal died at the age of around 60

Scientists finally clone human embryos

For some time, scientists have been able to craft precise genetic copies of many creatures. Whether they are animals, or single cells, they are similarly referred to as clones. For various technical and perceived ethical reasons, the procedures involved have been difficult to replicate for humans. Scientists in Oregon successfully used cloning to harvest human embryonic stem cells, a major scientific breakthrough that could help doctors develop tissue replacement treatment
