Diabetes reversed in mice with a pill mimicking high altitude hypoxia. Scientists say red blood cells hold the key.

People living at high altitude have long been observed to develop diabetes less often than those at sea level. Scientists now say they have identified a biological explanation for the trend.

Scientists have discovered that red blood cells act as hidden glucose sponges in low-oxygen conditions, explaining why people ...

While high blood pressure, diabetes and a sedentary lifestyle are linked to dementia, the exact molecular connection between ...
