Hospital infections associated with higher risk of dementia

A new meta-analysis published in Aging-US found a significant association between hospitalization for infections and the risk of developing dementia. Adults hospitalized with infections were at an increased risk of all-cause dementia, especially after a single infection-related hospitalization, which can speed up cognitive decline.

How to turn water into wine, with raisins

Researchers from Kyoto University found that soaking sun-dried raisins in water can create wine. The process facilitates the growth of yeast and results in higher ethanol concentrations.

Much-needed new drug approved for deadliest blood cancer

Researchers at the University of Virginia Health System have developed a new treatment for acute myeloid leukemia, a deadly form of blood cancer.
