Earth’s satellite problem isn’t unfixable, experts say
The average distance between the Moon and Earth is 382,500 kilometers (about 237674.48 miles). As such, there’s plenty of space around our planet to warrant all the satellites we put into orbit, right? Not necessarily. In fact, there are many who have growing concerns about Earth’s orbiting satellites, and the dangers they pose to spacecraft…

A New Mission Will Search for Habitable Planets at Alpha Centauri
Alpha Centauri is our closest stellar neighbor, a binary star system located just 4.376 light-years away. Despite its proximity, repeated astronomical surveys have failed to find hard evidence of extrasolar planets in this system. Part of the problem is that the system consists of two stars orbiting each other, which makes detecting exoplanets through the…

New Drug May Prevent the Evolution of COVID Variants
Until the incredibly infectious Omicron variant emerged and took over, it seemed like there was a never-ending stream of new SARS-CoV-2 variants. New variants may also continue to emerge. SARS-CoV-2, the virus that causes COVID-19, is known to infect human cells by attaching to ACE2 receptors on cell surfaces, and then dumping the viral genome…

A ‘hole’ 30 times Earth’s size has spread across the sun, blasting solar winds that’ll hit our planet by end of this week
A video from NASA’s Solar Dynamics Observatory shows the massive hole in the sun’s atmosphere.NASA/Solar Dynamics Observatory The sun is sporting a giant coronal hole that could fit 20-30 Earths across, back-to-back. Coronal holes blast rapid solar winds into space that travel 500-800 kilometers per second. The relatively-harmless winds should reach Earth by Friday for…

Study suggests that patients with baclofen pumps may safely undergo transcutaneous spinal stimulation
Photo shows a person with spinal cord injury wired for transcutaneous stimulation with electrodes taped over his mid spine. Credit: Kessler Foundation Researchers from Kessler Foundation and Kessler Institute for Rehabilitation (collectively termed “Kessler”) have conducted the first prospective study to assess whether transcutaneous spinal stimulation (TSS) interacts with implanted intrathecal baclofen (ITB) pump delivery…

How to Program Your Child’s Brain for Obesity
Is it different metabolic activity, environment, behavior, genetics? The connection between a mother and their child’s obesity is an active area of research. New findings shed light on how receiving too much nutrition early in life primes the brain for adult obesity. Children of obese women are more likely to develop obesity and type 2…

The universe might be shaped like a doughnut, not like a pancake, new research suggests
The universe could, in fact, be a giant doughnut, despite all of the evidence suggesting it’s as flat as a pancake, new research suggests. Strange patterns found in echoes of the Big Bang could be explained by a universe with a more complicated shape, and astronomers have not fully tested the universe’s flatness, the study…
