First Human Clone Embryos Created From Adults’ Skin Cells
"Scientists have created cloned embryos from the cells of two adults. This feat is the first hard evidence that it’s possible to create clones from cells taken from adult humans. The idea is that in the future, doctors could create cloned embryos of patients when the patients need an organ transplant, for example, or a set of new immune cells. The cloned embryos would serve as a source of stem cells for creating perfectly personalized transplants, no matter how old people are when they first get sick."
Health Trackers May Be the Rage, But How Useful Are They?
Low battery life, bulky appearance and lack of integration are some of the obstacles in the way before health trackers become the next gadgets we can’t live without.
Learn more about the ongoing evolution of this industry — and meet a woman who wears 27 fitness trackers — at KQED Science.
Could What You Believe About Your Food Affect Your Metabolism?
“Labels are not just labels; they evoke a set of beliefs,” says Alia Crum, a clinical psychologist who does research at the Columbia Business School in New York.
A couple of years ago, Crum found herself considering what seems like a pretty strange question. She wanted to know whether the information conveyed by a nutritional label could physically change what happens to you — “whether these labels get under the skin literally,” she says, “and actually affect the body’s physiological processing of the nutrients that are consumed.”
Even A Very Weak Signal From The Brain Might Help Paraplegics
“A treatment or cure for spinal cord injury remains elusive, but thestudyby researchers at the University of Louisville appears to add important information: Even a very weak signal from the brain can trigger movement.
To figure out what this means, we talked it over with John Donoghue, director of the Brown Institute for Brain Science and leader of the BrainGate II project, which in 2012 made it possible for two people immobilized by strokes to control a robotic arm with their thoughts. He wasn’t involved in the Louisville research.”
