Deducing the scale of tsunamis from the 'roundness' of deposited gravel
Posted on Sunday August 25, 2019
Scientists have found a link between the 'roundness' distribution of tsunami deposits and how far tsunamis reach inland. They sampled the 'roundness' of gravel from different tsunamis in Koyadori, Japan, and found a common, abrupt change in composition approximately 40% of the 'inundation distance' from the shoreline, regardless of tsunami magnitude. Estimates of ancient tsunami size from geological deposits may help inform effective disaster mitigation.

How diabetes can increase cancer risk: DNA damaged by high blood sugar
Posted on Sunday August 25, 2019
For years, scientists have been trying to solve a medical mystery: Why do people with diabetes have an increased risk of developing some forms of cancer? Today, researchers report a possible explanation for this double whammy. They found that DNA sustains more damage and gets fixed less often when blood sugar levels are high, thereby increasing cancer risk.
