This One Habit at Night Could Silently Change The Shape of Your Heart - ScienceAlert

Nobody likes the feeling of being constipated, but the consequences of being backed up might be more serious than you realize. Research shows that the amount of time poop sticks around in your body can have an overlooked impact on your health and quality of life, with constipation being a known risk factor for cardiovascular events, including heart attacks, heart failure, and stroke, among other complications. Fortunately, there are steps you can take to get things moving again, and one of the easiest strategies is simply doing some light exercise. We know that people who do regular exercise have less risk of developing constipation, whereas low levels of physical activity and high amounts of sedentary behavior may increase your chances of getting blocked. What's less clear, though, is what exercise actually does inside the body to help prevent or alleviate constipation, but a recent study published in Scientific Reports offers some plausible explanations – and suggests physical activity has an "immediate effect" on your gut, which could help ease the problem.

Exercise is well known for supporting physical fitness and mental well being. New research from BYU suggests it may also offer benefits for marriage, particularly when spouses are active together. The study, recently published in Family Relations, found that couples who exercised together reported better communication, more effective conflict resolution and less marital stress than couples who did not share physical activity.

Milky Way’s first microblazar candidate sits 12,000 light-years away, offering a rare ground-level lab for studying relativistic jetsA black hole 12,000 light-years away is firing a jet of plasma almost directly toward Earth. At that distance, no known or expected danger to Earth has been identified by the researchers or the institutions involved. What astronomers have actually found is rarer and more interesting than a threat. Researchers have identified IRAS 18293-0941 as a compelling candidate for the Milky Way’s first microblazar, a class of object that gives astrophysicists a close-up laboratory for studying some of the most violent physics in the galaxy. What Astronomers FoundThe discovery centers on a binary system whose black hole expels plasma jets at close to three-quarters the speed of light, pointed almost directly toward Earth. The system pairs a hot, massive star with a black hole that completes a full orbit roughly every 11.38 days. Material drawn from the companion star feeds the black hole, and some of that matter gets expelled outward as opposing jets traveling at approximately three-quarters the speed of light. Terminology matters here.
