If Dr. Ken Berry actually meant to say that you need to eat saturated fat for your nerves and brain, he flunks Biochem 101. First of all, your body can make all the saturated fat you need out of carbs and proteins. You don’t need to eat ANY saturated fat. Second, the most common fatty acid in your brain is the polyunsaturated fatty acid (PUFA) called DHA, which you DO need to eat, because you can’t make it from non-fats (you need to eat it in things like seafood, or at least the precursor omega-3 PUFA called ALA in cold-climate plants.) Ironically enough ALAis common in Canola oil, which Dr. Berry deprecates, but not in the tropical plant oils he likes. More on that later. A diet with a lot of saturated fat is NOT the best for the heart. The American Heart Association continues to recommend low saturated fat diets (with the missing sat-fat replaced by mono and polyunsaturated fat, not by carbohydrates) because the evidence from animal and human trials and even properly controlled epidemiology, shows these the best diets (see reference below–an extensive review of meta analyses [1]). Examples are the DASH hypertension diet and the closely-related Mediterranean diet (which has lots of olive oil for monounsaturated fatty acid, and seafood for DHA). If Dr. Berrythinks he has something better than the Mediterranean diet for longevity, what is his direct evidence? Saturated fat, of course, is used by the body to make cholesterol (you don’t need to eat any cholesterol for this reason), and it does raise cholesterol levels and it does increase atherosclerosis in nearly every controlled prospective experimental model in animals and humans. This is the gold standard of evidence in medicine.

One can go only so far with epidemiology, because occasionally when one bad thing (saturated fat) is heavily replaced for calories by another bad thing (certain carbohydrates) one detects no epidemiologic effect from changing just the first thing.

When it comes to vitamin D, most adults exhibit either frank deficiency, which results in clear clinical symptoms, or insufficiency, which often goes undetected. But how that insufficiency impacts physical health and the vulnerability of older adults to frailty as they age has been difficult to determine.

Now a University at Buffalo study of 24–28–month-old mice, the equivalent of 65-to-80-year-old adults, has found that frailty can be slowed with what might be considered “over” supplementation with vitamin D, referred to as “hypersufficiency.”

Published Sept. 30 in Nutrients, the research builds on previous work that Kenneth L. Seldeen, Ph.D., first author and research assistant professor in the Department of Medicine in the Jacobs School of Medicine and Biomedical Sciences at UB, has been conducting for more than a decade with colleague Bruce R. Troen, MD, professor of medicine and chief of the Division of Geriatrics and Palliative Medicine and director of the Center for Successful Aging, both in the Jacobs School.

Gets advanced, but some might like.

A research team from Cologne has discovered that a change in the DNA structure—more precisely in the chromatin—plays a decisive role in the recovery phase after DNA damage. The key is a double occupation by two methyl groups on the DNA packaging protein histone H3 (H3K4me2). The discovery was made by scientists under the direction of Prof. Björn Schumacher of the Cluster of Excellence for Aging Research CECAD, the Center for Molecular Medicine Cologne (CMMC), and the Institute for Genome Stability in Aging and Disease at the University of Cologne. The specific change enables genes to be reactivated and proteins to be produced after damage: The cells regain their balance and the organism recovers. The protective role of H3K4me2 was identified in experiments with the nematode Caenorhabditis elegans. The study has now been published in the journal Nature Structural & Molecular Biology.

The genome in every human cell is damaged on a daily basis, for example in the skin by UV radiation from the sun. Damage to the DNA causes diseases such as cancer, influences development, and accelerates aging. Congenital malfunctions in DNA repair can lead to extremely accelerated aging in rare hereditary diseases. Therefore, preservation and reconstruction processes are particularly important to ensure development and to maintain tissue function. DNA, which is rolled up on packaging proteins—the histones—like on cable drums, is regulated by methyl groups. Various proteins are responsible for placing methyl groups on histones or removing them. The number of groups on the packaging proteins affects the activity of genes and thus the protein production of the cell.

Alexey Turchin and Maxim Chernyakov, researchers belonging to the transhumanism movement, wrote a paper outlining the main ways technology might someday make resurrection possible.

From cryonics to time travel, here are some of the (highly speculative) methods that might someday be used to bring people back to life.

Perhaps in the future, gene editing may allow retinal regeneration in humans to reverse age-related vision deterioration.

Damage to the retina is the leading cause of blindness in humans, affecting millions of people around the world. Unfortunately, the retina is one of the few tissues we humans can’t grow back.

Unlike us, other animals such as zebrafish are able to regenerate this tissue that’s so crucial to our power of sight. We share 70 percent of our genes with these tiny little zebrafish, and scientists have just discovered some of the shared genes include the ones that grant zebrafish the ability to grow back their retinas.

Although it’s clearly NOT the approach taken for ultracold vitrification of patients undergoing life extension cryonization. (ULTRA🥶COLD being the exact opposite of ULTRA-BLOODY-H🥵T, obviously!)

Still, given the vast number of scientific and engineering discoveries and creations born on the backs of unexpected results, accidental discoveries, and outright screw up, it might have very useful data that has practical applications that would never otherwise have even been considered.

Italian scientists found intact brain cells in a man who was killed during the eruption of Mount Vesuvius in 79 AD.
