Physical activity crucial for poststroke recovery

A University of Gothenburg study shows that increased physical activity, with four hours of weekly exercise, doubles the chances of recovering well by six months after a stroke. Men and people with normal cognition tend to maintain an active lifestyle more often, leading to better recovery outcomes.

THE LANCET: An estimated one million stillbirths and newborn baby deaths could be prevented each year by implementing low-cost pregnancy interventions in low- and middle-income countries

Eight low-cost interventions can prevent an estimated 566,000 stillbirths and 5.2 million babies born preterm or small for gestational age each year. Implementing these interventions in 81 low- and middle-income countries could save the lives of millions of babies and improve long-term health outcomes.

A new twist on chirality: researchers extend the concept of directionality and propose a new class of materials

A team led by Taylor Hughes and Gaurav Bahl has experimentally realized a theoretical extension of chirality in two dimensions. They constructed a topological circuit network to explore new behaviors predicted by this extended chirality, which manifests as locking between a particle's flow direction and an arrow carried along with it.
