A study led by researchers at Georgia State reveals surprising new information about the relationship between neuron activity and blood flow deep in the brain, as well as how the brain is affected by salt consumption. When neurons are activated,... Continue Reading →
A near-Earth asteroid named Kamo`oalewa could be a fragment of our moon, according to a new paper published in Nature Communications Earth and Environment by a team of astronomers led by the University of Arizona. Kamo`oalewa is a quasi-satellite --... Continue Reading →
Why doesn't the nearby galaxy create a gravitational lensing effect on the background galaxy? It does, but since both galaxies are so nearby, the angular shift is much smaller than the angular sizes of the galaxies themselves. The featured Hubble image of NGC 3314 shows two large spiral galaxies... Continue Reading →
In a new study, researchers administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk. The research will be published in the Nov. 12 issue of... Continue Reading →
New research from the University of Otago has found that if you want someone to help you out with something, it is best not to set a deadline at all. But if you do set a deadline, make it short.Professor... Continue Reading →

Why, sometimes, does part of the Sun's atmosphere leap into space? The reason lies in changing magnetic fields that thread through the Sun's surface. Regions of strong surface magnetism, known as active regions, are usually marked by dark sunspots. Active regions can channel charged... Continue Reading →
The haze that blurs a blue sky or a beautiful skyline is caused by tiny particles called PM2.5. PM2.5 describes particulate matter, often made from pollution, less than 2.5 microns wide. Despite their microscopic size, PM2.5 are responsible for more than 4... Continue Reading →
