An ultra-rare disorder that causes muscle, tendons, and ligaments to irreversibly turn to bone, slowly forming a 'second skeleton' on top of the first, could soon be treatable at an earlier age than ever before.

The new work is a "big step forward" in finding new ways to generate viable organs for human transplants, but it comes with some ethical considerations

Physical activity, a factor in healthy brain aging, is part of multidomain dementia prevention trials. ISTOCK.COM/KALI9 Can diet and exercise lower your risk of dementia? Rigorous clinical trials aim to find out May. 27, 2021 , 1:00 PM For the past 3 years, about 6000 middle-aged and elderly Australians have pumped iron, loaded up on greens and whole grains, strived to quell stress, and challenged their wits with computer exercises, all in an effort to preserve their cognition. They’re part of a clinical trial called Maintain Your Brain, one of about 30 current or planned studies th...

Lab-grown embryos mix human and monkey cells for the first time Apr. 15, 2021 , 11:00 AM By slipping human stem cells into the embryos of other animals, we might someday grow new organs for people with faltering hearts or kidneys. In a step toward that goal, researchers have created the first embryos with a mixture of human and monkey cells. These chimeras could help scientists hone techniques for growing human tissue in species better suited for transplants, such as pigs. "The paper is a landmark in the stem cell and interspecies chimera fields,” says stem cell biologist Alejandro De Los A...
