Yes this says a 3 year epigenetic clock reversal in just 8 weeks thanks to diet and lifestyle changes. There is a list of supplements too:

Alpha ketoglutarate, vitamin C and vitamin A curcumin, epigallocatechin gallate (EGCG), rosmarinic acid, quercetin, luteolin.

Manipulations to slow biological aging and extend healthspan are of interest given the societal and healthcare costs of our aging population. Herein we report on a randomized controlled clinical trial conducted among 43 healthy adult males between the ages of 50–72. The 8-week treatment program included diet, sleep, exercise and relaxation guidance, and supplemental probiotics and phytonutrients. The control group received no intervention. Genome-wide DNA methylation analysis was conducted on saliva samples using the Illumina Methylation Epic Array and DNAmAge was calculated using the online Horvath DNAmAge clock (2013). The diet and lifestyle treatment was associated with a 3.23 years decrease in DNAmAge compared with controls (p=0.018). DNAmAge of those in the treatment group decreased by an average 1.96 years by the end of the program compared to the same individuals at the beginning with a strong trend towards significance (p=0.066). Changes in blood biomarkers were significant for mean serum 5-methyltetrahydrofolate (+15%, p=0.004) and mean triglycerides (−25%, p=0.009). To our knowledge, this is the first randomized controlled study to suggest that specific diet and lifestyle interventions may reverse Horvath DNAmAge (2013) epigenetic aging in healthy adult males. Larger-scale and longer duration clinical trials are needed to confirm these findings, as well as investigation in other human populations.

Advanced age is the largest risk factor for impaired mental and physical function and many non-communicable diseases including cancer, neurodegeneration, type 2 diabetes, and cardiovascular disease [1, 2]. The growing health-related economic and social challenges of our rapidly aging population are well recognized and affect individuals, their families, health systems and economies. Considering economics alone, delaying aging by 2.2 years (with associated extension of healthspan) could save $7 trillion over fifty years [3]. This broad approach was identified to be a much better investment than disease-specific spending. Thus, if interventions can be identified that extend healthspan even modestly, benefits for public health and healthcare economics will be substantial.

The Future of Everything covers the innovation and technology transforming the way we live, work and play, with monthly issues on health, money, cities and more. This month is Education & Learning, online starting Aug. 6 and in the paper on Aug. 13.

No one has yet deciphered the brain signals that encode a complex thought, turn an idea into words or make a lasting memory. But powerful clues are emerging to drive the neurotechnology of learning, scientists say.

On the frontier of neuroscience, researchers are inventing devices to enhance learning abilities, from wearable nerve stimulators that boost mental focus to headsets for wireless brain-to-brain communication.

The NIH-led Brain Research through Advancing Innovative Neurotechnologies® (BRAIN) Initiative continues to teach us about the world’s most sophisticated computer: the human brain. This striking image offers a spectacular case in point, thanks to a new tool called Visual Neuronal Dynamics (VND).

VND is not a camera. It is a powerful software program that can display, animate, and analyze models of neurons and their connections, or networks, using 3D graphics. What you’re seeing in this colorful image is a strip of mouse primary visual cortex, the area in the brain where incoming sensory information gets processed into vision.

This strip contains more than 230,000 neurons of 17 different cell types. Long and spindly excitatory neurons that point upward (purple, blue, red, orange) are intermingled with short and stubby inhibitory neurons (green, cyan, magenta). Slicing through the neuronal landscape is a neuropixels probe (silver): a tiny flexible silicon detector that can record brain activity in awake animals [1].

Pear-shaped people, whose weight is generally distributed more evenly, rather than “apple shaped” individuals with fat clustered around their middle and often around internal organs like the liver in the abdominal cavity, are considered less at risk for cardiometabolic problems like heart disease and diabetes, as well as cognitive decline, says Stranahan, neuroscientist at the Medical College of Georgia at Augusta University.

Summary: Adipocytes, or beige fat cells, are indispensable to the anti-inflammatory and neuroprotective effects of subcutaneous fat, researchers say.

Beige is considered a calming paint color, and scientists have new evidence that beige fat has a similar impact on the brain, bringing down the inflammation associated with the more common white fat and providing protection from dementia.

They have found that beige fat cells, which are typically intermingled with white fat cells in the subcutaneous fat present on “pear shaped” people, mediate subcutaneous fat’s brain protection, Dr. Alexis M. Stranahan and her colleagues report in the journal Nature Communications.

The ones Teresa is handling in this Cambridge laboratory are mini bile ducts, thin tubes that carry bile from the liver to the small intestine to help with digestion.

Teresa also has gut organoids in the incubator, while down the corridor a different team is developing brain organoids.

In fact, around the world, miniatures of everything from lungs to kidneys are being coaxed gently to life. And because they function just as organs do, they are perfect for research.

Summary: Brain connectivity at birth may impact emotional processing and social development later in childhood, especially in children born preterm. Researchers found children born preterm with a weaker uncinate fasciculus, the white-matter tract that connects brain regions associated with emotional processing, were more likely to interpret situations in a negative light.

The strength of brain connections at birth may predict the future emotional and social development of babies born prematurely, according to new research published in eNeuro.

Evidence has been accumulating for almost a decade that the microbiome composition changes with age. In 2,012 research by my colleagues at University College Cork showed that diversity in the microbiome was linked to health outcomes in later life, including frailty.

In 1,895 on turning 50 Elie Metchnikoff became increasingly anxious about aging. As a result, the Russian Nobel prize-winning scientist, and one of the founders of immunology, turned his attention away from immunology and towards gerontology – a term that he coined.

He was fascinated by the role that intestinal bacteria play in health and disease and suggested that people from parts of eastern Europe lived longer because they ate a lot of fermented foods containing lactic acid bacteria.

Although popular at the time, this theory linking gut microbes to healthy aging was largely ignored by scientists until relatively recently. We now recognize the importance that the trillions of bacteria, known as the gut microbiome, have in regulating health and disease.
