Scientists have uncovered a novel antibiotic-free approach that could help prevent and treat one of the most widespread bacterial pathogens, using nanocapsules made of natural ingredients.
The UCSF scientists who identified the two known human genes that promote “natural short sleep” – nightly sleep that lasts just four to six hours but leaves people feeling well-rested – have now discovered a third, and it’s also the first gene that’s ever been shown to prevent the memory deficits that normally accompany sleep deprivation. The researchers believe this latest discovery may one day lead to a druggable target for therapies that improve sleep and treat sleep disorders.
In symptom-free individuals, the detection of misfolded amyloid-β protein in the blood indicated a considerably higher risk of Alzheimer's disease – up to 14 years before a clinical diagnosis was made. Amyloid-β folding proved to be superior to other risk markers evaluated, as shown by scientists from the German Cancer Research Center (DKFZ), Ruhr University Bochum (RUB), the Saarland Cancer Registry, and the Network Aging Research at Heidelberg University.
In a world first, a team of Australian-led researchers has discovered a uniquely shaped fungus in pristine waters, which may mimic opioids with fewer side-effects. It had been hoped that such a molecular structure might exist.
