New Research Finds That People With Anorexia Have Smaller Brains

Lead Image: Anorexia is an eating disorder that causes individuals to be overly concerned with their appearance and diet. The largest study to date reveals significant alterations in brain structure in anorexic individuals. Important differences in the brains of those with and without anorexia nervosa have been found, according to a major study headed by neuroscientists at the University of Bath (UK) that involved worldwide collaborators. In the UK, nearly a quarter of a million individuals aged 16 and older are affected by anorexia, a severe eating disorder, and mental health condition. Symptoms include individuals seeking to maintain the lowest possible…

Where to Focus Your Attention for Online Business Presence

Creating an online presence for your business is essential, especially if you have yet to do so.

Image by Hennie Otto The new research adds to our knowledge of how Great Whites employ their “flight” instincts to evade predators over long periods of time and in groups. Large numbers of Great White Sharks have been driven away from their normal gathering place by a pair of Orca (Killer Whales) who have been terrorizing and slaughtering the sharks off the coast of South Africa since 2017. New research published…

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

Lead Image: 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 most closely linked to developing melanoma. In fact, sunburns have been associated with doubling one’s risk of melanoma. Because sunscreen can block UV rays and therefore reduce the risk of sunburns, it ultimately may reduce the risk of developing melanoma. Therefore, the promotion of sunscreen as an effective melanoma prevention strategy is a reasonable public…

MIT’s Tiny Robotic Lightning Bugs Take Flight

Lead Image: 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 their luminescence for communication — to attract a mate, ward off predators, or lure prey. These glimmering fireflies also sparked the inspiration of researchers at MIT. Taking a cue from nature, they constructed electroluminescent soft artificial muscles for flying, insect-scale robots. The tiny…
