Dark matter could make our galaxy's innermost stars immortal

Stars near the center of our galaxy are acting kind of weird. Dark matter may be the explanation.

Stars near the center of our galaxy are acting kind of weird. Dark matter may be the explanation. A team of scientific detectives (so to speak) have discovered a potential new class of stars that could exist within a light-year of the Milky Way's center that could be operating according to an unusual mechanism: dark matter annihilation. This process would produce an outward pressure on the stars other than hydrogen fusion, keeping them from gravitationally collapsing—and making them essentially immortal, their youth being refreshed constantly. The findings are published on the arXiv preprint server. Collectively, the dark matter–powered stars would inhabit a new region of a long-established diagram that classifies stars by their temperature and luminosity, placing them away from the so-called main sequence where the vast majority of stars exist.

Absolutely beautiful! I hope everyone took this in! Makes you think just how small we are. A moment the world comes together as one! That’s true humanity . We will be uploading more amazing photos to this same post. So come back later on and check out our 2024 once in a lifetime eclipse photos.

New 'Exercise Pill' Could Induce Fitness Benefits Without Exercise

Scientists in the US claim to have boiled down some of the health benefits of exercise into a swallowable pill.

Scientists in the US claim to have boiled down some of the health benefits of exercise into a swallowable pill. The novel drug is in the very early stages of development, but in initial experiments on rodents, the medicine appears to tap into a natural metabolic pathway usually triggered by exercise. When administered to mice daily, the drug, called SLU-PP-332, seems to improve muscle function, fitness, and endurance – all without the animals having to move more than they're used to.

It's very endearing to me how many people are willing to keep an eye on a video feed so they can push a button and let a fish in the Netherlands get to the other side of a dam.
