A malaria vaccine has been particularly elusive in the medical community because malaria originates from a parasite and not a virus. Therefore, a live but weakened form of the parasite that infects humans was used in the creation of this new investigational vaccine, Sanaria® PfSPZ. The weakened sporozoites parasite was developed by Sanaria Inc. through a clinical study conducted by researchers from the National Institute of Health’s (NIH)
As far as cancers go, one of the worst is a type of brain cancer called glioma - the disease has a five-year survival rate of just 5 percent, and no reliable method for early detection.
A giant study that pooled genetic data from tens of thousands of people could change that, finding more than a dozen new mutations for physicians to hunt for in an effort to identify who is at risk of developing glioma.
Scientists at the Gladstone Institutes discovered a key mechanism that protects mice from developing a human disease of aging, and begins to explain the wide spectrum of disease severity often seen in humans. Both aspects center on the critical role of telomeres, protective caps on the ends of chromosomes that erode with age.
Researchers have developed a line immortal stem cells that allow them to generate an unlimited supply of artificial red blood cells on demand.
If these artificial blood cells pass clinical trials, they'll be far more efficient for medical use than current red blood cell products, which have to be generated from donor blood - and would be a huge deal for patients with rare blood types, who often struggle to find matching blood donors.
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...
