If you’ve ever seen yourself through a thermal imaging camera, you’ll know that your body produces lots of heat. This is in fact a waste product of our metabolism. Every square foot of the human body gives off heat equivalent to about 19 matches per hour. Unfortunately, much of this heat simply escapes into the … Read more
In an early-stage clinical trial, scientists used designer immune cells to “reboot” the immune systems of patients with various autoimmune diseases. The trial used a form of chimeric antigen receptor (CAR) T cell therapy, which has become a mainstay treatment for blood cancers, like leukemia. Only a few patients were included in this initial trial, … Read more
Tardigrades, the ubiquitous microscopic animals that resemble gummy bears with eight legs, are renowned for their ability to survive some of the harshest environmental conditions for decades without food and water. These hardy animals can easily endure levels of radiation that would be lethal to most other forms of life, extreme temperatures and even survive … Read more
Forgetting is part of our daily lives. You may walk into a room only to forget why you went in there — or perhaps someone says hi on the street and you can’t remember their name. But why do we forget things? Is it simply a sign of memory impairment, or are there benefits? One … Read more
Miniature livers will fly aboard the International Space Station in an upcoming study on whether microgravity can encourage the growth of healthy tissue with an ample blood supply. It’s an effort that could potentially lead to personalized, space-grown tissues and organs for use in transplant surgeries, scientists say. In two upcoming experiments, researchers plan to … Read more
Imagine you are in a soccer match, and it’s tied. Each team will begin taking penalty kicks. The crowd is roaring, and whether or not your team wins the game depends on your ability to hit the shot. As you imagine this scene, are you able to picture the scenario with colors and details? Scientists … Read more
Plants can grow with much less light than previously thought, according to a new study on tiny water-based organisms called microalgae that has been published in Nature Communications. The German-led team of researchers lowered light sensors into Arctic water to a depth of 164 feet (50 metres) to test how low light levels must become … Read more
Memories evolve throughout our lifetimes, changing as we learn and experience new things and as we recall a memory repeatedly. And then, memories degrade as we age. Previously, scientists thought that this malleability was the result of changes in the brain cells that originally encoded the memory, and they believed these cells stored just one … Read more
The human body does not age at a constant rate throughout adulthood — instead, it accelerates dramatically around ages 44 and 60, a new study finds. The new research, published Aug. 14 in the journal Nature Aging,involved measuring more than 11,000 molecules in the adult body over time, and it revealed that 81% of them … Read more
Scientists have invented an injectable “goo” that can regrow cartilage in the body. For now, they’ve only tested it in sheep, but it could someday be used to repair joint damage in humans, the researchers say. In particular, they hope the goo can treat damage caused by degenerative diseases, such as osteoarthritis, and sports-related injuries, … Read more
