Scientists create microscopic ‘swimmers’ controlled by a magnetic field

A one-torso, one-arm swimmer made of magnetically linked particles moves under the influence of an eccentric magnetic field. Rice University researchers believe it represents the simplest possible form of locomotion.

International research consortium identifies 22 new genetic risk factors for stroke

March 13, 2018 An international research consortium studying 520,000 individuals from around the world has identified 22 new genetic risk factors for stroke, thus tripling the number of gene regions known to affect stroke risk. The results demonstrate shared genetic influences with multiple related vascular conditions, especially blood pressure, but also coronary artery disease, venous […]

Self-adhering chest patch may better detect common heart rhythm disorder than usual care

March 12, 2018 For people at heightened risk for atrial fibrillation (AFib)—a common heart rhythm disorder that also carries a high risk of stroke—wearing a self-adhering chest patch that records heart patterns may better detect the condition and facilitate more timely treatment than relying on usual care, according to one-year data being presented at the […]
