Climate change won't reduce deaths in winter

A new study published in Nature Climate Change found no link between warmer winters and reduced excess winter death rates in the UK. Instead, flu activity was identified as the main cause of year-to-year variation in winter mortality.

Researchers create synthetic version of heparin for use in kidney patients

A team led by Robert Linhardt and Jian Liu created a synthetic form of low-molecular-weight heparin, which can be reversed in cases of overdose and is safer for patients with poor kidney function. The new drug is also cost-effective and has improved properties compared to the animal-derived alternative.
