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.

Aubrey de Grey, Longevity, Diet and Aging. Aubrey de Grey PhD is an English author and biomedical gerontologist and mathematician who has made a significant contribution to the Hadwiger–Nelson problem. He is currently the Chief Science Officer of the SENS Research Foundation and VP of New Technology Discovery at AgeX Therapeutics, Inc. He is editor-in-chief of the academic journal Rejuvenation Research, author of The Mitochondrial Free Radical Theory of Aging (1999) and co-author of Ending Aging (2007). He is known for his view that medical technology may enable human beings alive today not to die from age related causes.
In 2013 a study; 2-year old mice were tested for muscle wastage, insulin resistance and inflammation; in humans all are used as indicators of the aging process, they were then given NMN for 1 week. In all cases, after only 1 week the 2-year old mice were reflecting the expected findings of 6-month-old mice in the areas of muscle wastage, insulin resistance and inflammation.
In a later study (2018) Dr. David Sinclair’s team at the Harvard Medical School found that the aging of blood vessels had been reversed. The study showed that mice that were given NMN had restored blood vessel growth and had increased muscle endurance by up to 80%.
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.
The past year or so has seen an energetic debate over whether or not new neurons are generated in the adult human brain, a process known as neurogenesis. This process is well known and well studied in mice, and thought to be very important in the resilience and maintenance of brain tissue. The human data has always been limited, however, due to the challenges inherent in working with brain tissue in living people, and it was assumed was that the mouse data was representative of the state of neurogenesis in other mammals. In this environment, the publication of a careful study that seemed to rule out the existence of neurogenesis in adult humans produced some upheaval, and spurred many other teams to assess the human brain with greater rigor than was previously the case.
So far, all of the following studies published so far do in fact show evidence of adult neurogenesis in humans. This is the better of the two outcomes, as the regenerative medicine community has based a great deal of work on the prospect of being able to upregulate neurogenesis in order to better repair injuries to the central nervous system, or partially reverse the decline of cognitive function in the aging brain. The study here is particularly reassuring, as it shows that even in very late life there are signs that new neurons are being generated in the brain.
A new therapy that appears to stop Parkinson’s disease “in its tracks” will begin phase-one clinical trials in humans next year.
The therapy, developed by researchers at the University of Queensland – and partly under-written by the Michael J Fox Foundation – is a world first because it stops the death of brain cells in Parkinson’s sufferers rather than managing symptoms.
If human trials echo the stunning results in animal testing, the inflammation of the brain that causes so much of the progressive damage in Parkinson’s disease (PD) could be halted by taking a single pill each day.
