New evidence for a direct sugar-to-diabetes link: Results of a large epidemiological study suggest sugar may also have a direct, independent link to diabetes. Stanford researchers and colleagues analyzed data on sugar availability and diabetes rates from 175 countries over the past 10 years; after accounting for obesity and a large array of other factors, the findings showed that increased sugar in a population’s food supply was linked to higher diabetes rates, independent of obesity rates.
“What’s that?” Stanford researchers identify cells important to hearing loss: Stanford researchers have discovered a group of progenitor cells in the inner ear that can become the sensory hair cells and adjacent supporting cells that enable hearing. Future research on these progenitor cells holds the promise to yield treatments that could help millions of Americans suffering from hearing loss due to damaged or impaired sensory hair cells.
