B Vitamins May Be Inexpensive Treatment for Advanced Non-Alcoholic Fatty Liver Disease

Singapore scientists find hyperhomocysteinemia strongly correlates with the severity of non-alcoholic steatohepatitis. Scientists at Duke-NUS Medical School, Singapore, have discovered that elevated blood levels of an amino acid called homocysteine correlate strongly with the severity of an advanced form of non-alcoholic fatty liver disease. They also found vitamin B12 and folic acid (vitamin B9) could … Read more

MIT’s Tiny Robotic Lightning Bugs Take Flight

Inspired by fireflies, MIT scientists have created soft actuators that can emit light in different colors or patterns. Credit: Courtesy of the researchers Inspired by fireflies, scientists create insect-scale robots that can emit light when they fly, which enables motion tracking and communication. Lightning bugs that light up dusky backyards on warm summer evenings use … Read more

It’s a Myth That Sunscreen Prevents Melanoma Skin Cancer in People of Color – A Dermatologist Explains

By Adewole S. Adamson, University of Texas at Austin August 10, 2022 There is very little evidence that sunscreen reduces melanoma in dark-skinned people. Melanoma is a potentially deadly form of skin cancer that affects people of every racial and ethnic group. Exposure to ultraviolet, or UV, rays from the sun is the risk factor … Read more

Galactic Archeologists Discover “Fossil” of One of the First Ever Galaxies

A unique ultra-faint dwarf galaxy has been discovered in the outer fringes of the Andromeda Galaxy thanks to the sharp eyes of an amateur astronomer examining archival data from the US Department of Energy-fabricated Dark Energy Camera on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) and processed by the Community … Read more

Georgia Tech Researchers Defy Standard Laws of Physics

Researchers have proven that when bodies exist in curved spaces, they can in fact move without pushing against something. Robotic Motion in Curved Space Defies Standard Laws of Physics When humans, animals, and machines move throughout the world, they always push against something, such as the ground, air, or water. Until recently, physicists thought this … Read more
