Alzheimer's trial screening data links high amyloid levels with early stage disease  

A new study supports the hypothesis that higher levels of amyloid protein in the brain represent an early stage of Alzheimer's disease. Screening data for the study show that amyloid burden in clinically normal older adults is associated with a family history of disease, lower cognitive test scores, and reports of declines in daily cognitive function.

Upper ocean water masses shrinking in changing climate: Less efficient CO2 sink  

The oceans help buffer the Earth from climate change by absorbing carbon dioxide and heat at the surface and transporting it to the deep ocean. New research indicates the North Atlantic Subtropical Mode Water, an upper ocean water mass, is shrinking in a changing climate and becoming a less efficient sink for heat and carbon dioxide.

Shorter radiotherapy treatment for bowel cancer patients during COVID-19  

An international panel of cancer experts has recommended a one-week course of radiotherapy and delaying surgery as the best way to treat patients with bowel cancer during the COVID-19 pandemic. The short course of treatment involves higher-intensity radiation rather than five weeks of radiotherapy coupled with chemotherapy. Surgery, which normally happens one to two weeks after radiotherapy, can be safely delayed by up to 12 weeks, say the expert panel.

In overweight and obese Chinese men and women, larger thigh circumferences were associated with lower blood pressure. These findings suggest that carrying more weight on the thighs may be a marker of better heart health in Chinese obese and overweight people, who are at a greater risk of heart disease.
