We owe our long lives to stem cells, which are nestled deep inside certain tissues in the body and constantly replace old cells. In recent years scientists have been able to correct genetic diseases by removing these stem cells, editing their genomes and then implanting them back into the patient, but that adds complications. Now, new research led by Harvard scientists has successfully edited the genes of stem cells while still in the body.

Companies and governments are gaining new powers to follow people across the internet and around the world, and even to peer into their genomes. The benefits of such advances have been apparent for years; the costs — in anonymity, even autonomy — are now becoming clearer. The boundaries of privacy are in dispute, and its future is in doubt. Citizens, politicians and business leaders are asking if societies are making the wisest tradeoffs. The Times is embarking on this monthslong project to explore the technology and where it’s taking us, and to convene debate about how it can best help realize human potential.
The New York Times is launching an ongoing examination of privacy. We’ll dig into the ideas, history and future of how our information navigates the digital ecosystem and what’s at stake.
Severe headache sufferers will be given a gadget rather than pills to alleviate the pain, the head of NHS England announced on Wednesday.
Cluster headaches, which are often mistaken for migraines, are one of the most debilitating conditions known to medical science, with women often describing the pain as worse than childbirth.
Now sufferers will be offered a hand-held device that delivers mild electrical stimulation to the vagus nerve to block the pain signals that cause the headaches.
The red meat or white meat debate is a draw: Eating white meat, such as poultry, will have an identical effect on your cholesterol level as eating red beef, new research indicates.
The long-held belief that eating white meat is less harmful for your heart may still hold true, because there may be other effects from eating red meat that contribute to cardiovascular disease, said the University of California, San Francisco researchers. This needs to be explored in more detail, they added.
Non-meat proteins such as vegetables, dairy, and legumes, including beans, show the best cholesterol benefit, according to the new study published Tuesday in the American Journal of Clinical Nutrition.
The growing interest in cannabis and cannabis-derived products has sparked uncertainty and concern over the industry’s lack of regulations. On Thursday, the FDA held a hearing that looked deeper into the science and safety concerns that surround marijuana and CBD.
Medical Marijuana Inc (MJNA) CEO Stuart Titus is optimistic about the effects that cannabis-derived products have on humans.
“We have a very large self-regulatory system in our human bodies called the internal or the endogenous cannabinoid system,” Titus told YFi AM (video above). “And basically since cannabis has been removed from our diets for the past 80-plus years, many of us are cannabinoid deficient, and thus we start taking a nice supplementary-size serving of CBD. Many people are moving to a much higher level of overall health and wellness.”

Rejuvenation is a medical discipline focused on the practical reversal of the aging process.
Rejuvenation is distinct from life extension. Life extension strategies often study the causes of aging and try to oppose those causes in order to slow aging. Rejuvenation is the reversal of aging and thus requires a different strategy, namely repair of the damage that is associated with aging or replacement of damaged tissue with new tissue. Rejuvenation can be a means of life extension, but most life extension strategies do not involve rejuvenation.

A group of Spanish researchers, including Dr. Maria Blasco and others at the CNIO, have published a new study that examines the consequences of short telomeres and telomerase deficiency on the brain [1].
This study addresses an aspect of telomere attrition, one of the primary hallmarks of aging. Telomeres are repeating sequences of DNA (TTAGGG) that can can reach a length of 15,000 base pairs and appear at the ends of chromosomes, acting as protective caps. They prevent damage, stop chromosomes from fusing with each other, and prevent chromosomes from losing base pair sequences at their end during cell replication.
