Researchers have identified a cellular mechanism that allows them to reverse ageing in mouse DNA and protect it from future damage.
They've shown that by giving a particular compound to older mice, they can activate the DNA repair process and not only protect against future damage, but repair the existing effects of ageing. And they're ready to start testing in humans within six months.
Researchers have successfully used spinach leaves to build functioning human heart tissue, complete with veins that can transport blood.
To tackle a chronic shortage of donor organs, scientists have been working on growing various tissues and even whole organs in the lab. But culturing a bunch of cells is only part of the solution - they simply won't thrive...
Type 2 diabetes is generally considered to be a chronic health condition that can't be cured once it develops, and can only be managed with a combination of medication and healthy living – assisted by gastric band (bariatric) surgery in some cases.
But new research suggests that people may actually be able to beat the disease for set periods, by undertaking an intensive short-term course of medical treatment that's been shown...
Taking popular heartburn drugs for prolonged periods has been linked to serious kidney problems, including kidney failure. The sudden onset of kidney problems often serves as a red flag for doctors to discontinue their patients' use of so-called proton pump inhibitors (PPIs), which are sold under the brand names Prevacid, Prilosec, Nexium and Protonix, among others.
Since 1995, hundreds of poor children in Muzaffarpur, India have mysteriously suffered seizures and feelings of brain fogginess, usually in the morning. Many would soon die. This happened every year between May and July: In 2014, for example, Muzaffarpur hospitals admitted 390 kids with the symptoms, resulting in 122 deaths.
Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants.
It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera – named after the cross-species beast of Greek mythology – has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch.
Scientists have engineered the first ever 'semi-synthetic' organisms, by breeding E. coli bacteria with an expanded, six-letter genetic code.
While every living thing on Earth is formed according to a DNA code made up of four bases (represented by the letters G, T, C and A), these modified E. coli carry an entirely new type of DNA, with two additional DNA bases, X and Y, nestled in their genetic code.
