Astronomy and anthropology have blended to help determine what might have triggered the decline of a major North American society 1,600 years ago. A vibrant culture lived in the Ohio Valley from about 200 BCE to 300 CE. These people were the ancestors of many modern Native American tribes, such as the Haudenosaunee (Iroquois) and … Read more

In 2017, Michel Roccati was in a motorbike accident that left his lower body completely paralyzed. In 2020, he walked again, thanks to a breakthrough new spinal cord implant. The implant sends electrical pulses to his muscles, mimicking the action of the brain, and could one day help people with severe spinal injuries stand, walk, … Read more
Israeli scientists said they found “striking” differences in the chances of getting seriously ill from COVID-19 when they compared patients who had sufficient vitamin D levels prior to contracting the disease, with those who didn’t. A study published Thursday in research journal PLOS One found that about half of people who were vitamin D deficient before getting COVID-19 … Read more
Three men paralyzed in motorcycle accidents have become the first success stories for a new spinal stimulation device that could enable faster and easier recoveries than its predecessors. The men, who had no sensation or control over their legs, were able to take supported steps within 1 day of turning on the electrical stimulation, and … Read more
For decades doctors and researchers have dabbled with using electrical stimulation of the spinal cord to help restore movement in people with paralysis. The technique, when combined with physical therapy, has even allowed some patients with complete paralysis to walk again. Yet it has not worked for all paralyzed people. And researchers still have had … Read more
There is perhaps no better way to see the absolute pinnacle of human athletic abilities than by watching the Olympics. But at the Winter Games this year – and at almost all professional sporting events – you rarely see a competitor over 40 years old and almost never see a single athlete over 50. … Read more
Humans’ sense of smell may indeed be gradually fading, according to a study that has found people carry different versions of two scent receptors for musk and body odor. Olfactory receptors detect airborne chemicals that waft into our noses, but smell receptors vary immensely from one person to the next. Any two people, on … Read more
