Long-term exposure to low levels of air pollution increases risk of heart and lung disease
Analysis of records for more than 63 million Medicare enrollees from 2000 to 2016 finds long-term exposure to air pollution had a significant impact on the number of people hospitalized for cardiac and respiratory conditions. Researchers examined three components of air pollution: fine particulate matter, nitrogen dioxide and ozone. Even levels lower than national standards affected heart and respiratory illnesses.

Yale neurologists identify consistent neuroinflammatory response in ICH patients
Understanding how the immune system responds to acute brain hemorrhage could open doors to identifying treatments for this devastating disease. However, up until now, there has been limited information on inflammation in the brain from human patients, especially during the first days after a hemorrhagic stroke. This led a team of researchers to partner with a large clinical trial of minimally-invasive surgery to tackle defining the human neuroinflammatory response in living patients. (2021-02-22)

Stroke of luck: Scientists discover target for stroke therapy in blood-brain barrier
The blood-brain barrier prevents immune cells from circulating freely in the brain, and the breakdown of its function is a major cause of post-stroke inflammation. Now, for the first time, researchers have identified how a toxic stroke byproduct, acrolein, could activate the barrier-degrading enzyme proheparanase (proHPSE). The research group has discovered that proHPSE degrades the glycocalyx within the post-stroke brain's blood vessels, providing hope for new and effective therapeutics against post-stroke inflammation.

Butterfly wing clap explains mystery of flight
The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers at Lund University in Sweden have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a highly effective clap technique, therefore making use of their unique wings. This helps them rapidly take off when escaping predators. (2021-01-20)
