Increasing physical activity to recommended levels over as few as 6 years in middle age is associated with a decreased risk of heart failure, according to a study published recently in the journal Circulation. The same study found that as little as six years without physical activity in middle age was linked to an increased risk of the disorder. Six years of exercise, or lack of it, may be enough to change heart failure risk. Image credit: Skeeze. Unlike...

Artist’s illustration of Jupiter and Europa with NASA’s Galileo spacecraft after its pass through a plume erupting from Europa’s surface. A new computer simulation gives us an idea of how the magnetic field interacted with a plume. The magnetic field lines (depicted in blue) show how the plume interacts with the ambient flow of Jovian plasma. The red colors on the lines show more dense areas of plasma.

Panoz-Brown et al show that rats remember a stream of multiple episodes and the order in which they occur by engaging hippocampal-dependent episodic memory replay; rats remember the order of events using episodic memory replay and that replay is part of long-term memory, resistant to interference, and hippocampal dependent. The discovery could help advance the development of new drugs to treat Alzheimer’s disease. Image credit: Panoz-Brown et al, doi: 10.1016/j.cub.2018.04.006.
