Just about everyone may want to look and feel younger and healthier, but multimillion-dollar investments and broccoli smoothies are not for everyone. Still, that doesn’t mean the less hardcore among us are out of luck if we’re hoping to turn back the clock on our brain health.

New research by a team of psychologists uncovered a simple way just about anyone can get their brain working like it’s decades younger.

You probably don’t need science to tell you this, but people’s cognitive acuity generally starts to level off in their 30s and 40s before declining more markedly in their 60s. Most of us write our slower responses and memory lapses off to the unavoidable indignities of aging. But what if they were just the adult equivalent of the “summer slide” that affects kids, a pair of researchers wanted to know.

Though drug developers have achieved some progress in treating Alzheimer’s disease with medicines that reduce amyloid-beta protein, other problems of the disease, including inflammation, continue unchecked. In a new study, scientists at The Picower Institute for Learning and Memory at MIT describe a candidate drug that in human cell cultures and Alzheimer’s mouse models reduced inflammation and improved memory.

The target of the new “A11” molecule is a genetic transcription factor called PU.1. Prior research has shown that amid Alzheimer’s disease, PU.1 becomes an overzealous director of inflammatory gene expression in the brain’s microglia immune cells. A11 suppresses this problematic PU.1 activity, the new research shows, by recruiting other proteins that repress the inflammatory genes PU.1 works to express. But because A11 concentrates mostly in the brain and does not reduce PU.1 levels, it does not appear to disrupt PU.1’s other job, which is to ensure the production of a wide variety of blood cells.

“Inflammation is a major component of Alzheimer’s disease pathology that has been especially hard to treat,” says study senior author Li-Huei Tsai, Picower Professor of Neuroscience at MIT and director of The Picower Institute and MIT’s Aging Brain Initiative. “This preclinical study demonstrates that A11 reduces inflammation in human microglia-like cells, as well as in multiple mouse models of Alzheimer’s disease, and significantly improves cognition in the mice. We believe A11 therefore merits further development and testing.”

As we age, our muscles and other tissues break down in much the same way as degenerative diseases progress. What we learn from studying degenerative diseases such as muscular dystrophy could help researchers develop new interventions to fight common age-related ailments and chronic illnesses.

With help from NIA, biotechnology company Juvena Therapeutics has begun unlocking the secrets of proteins for regenerative medicine. Juvena scientists are using a form of muscular dystrophy — myotonic dystrophy type 1 (DM-1) — as a model to sift through proteins that are produced by the body’s stem cells. These cells have the potential to become any type of cell in the body, from liver tissue to skin cells. The goal is to find proteins that encourage tissue growth and repair, ultimately designing new drugs to prevent and treat degenerative diseases like DM-1. As part of this process, Juvena hopes to learn more about how to reduce the effects of aging on muscles and other tissues, too.

A new biotech trying to establish itself can feel isolated from the larger scientific community. For example, Juvena is unable to submit findings for publication before taking care of intellectual property protections. But NIH’s peer-review process offered confidential, scientifically rigorous feedback to fill that critical gap, and the NIA Small Business Programs staff offered helpful advice.

A fortnightly meetup for the Transhumanism movement in Sydney to discuss the latest developments in emerging technology and product roadmap.

Insights into healing and aging were discovered by National Institutes of Health researchers and their collaborators, who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence. According to the study published in Cell Reports, Hydractinia demonstrates that the fundamental biological processes of healing and aging are intertwined, providing new perspective on how aging evolved.

This November, researchers, clinicians, and investors will descend on Miami, Florida for the annual Wonderland conference. This year, the world’s leading psychedelics conference is expanding its focus to include longevity for the first time, welcoming top speakers from across the field, from Bryan Johnson to Aubrey de Grey.

Through a series of keynotes, round table and panel discussions, and town hall open mic sessions, the event aims to explore the increasingly linked topics of psychedelic medicine, mental health, and longevity medicine.

Longevity. Technology: Every month it seems, more and more research is highlighting the connection between mental health and longevity – from accelerated biological aging to reduced life expectancy. With psychedelics simultaneously demonstrating compelling results in the treatment of mental conditions, from depression to PTSD, the synergies between longevity and psychedelic medicine are clear. We caught up with leading longevity physician Dr Halland Chen to tap into his views on recent developments in longevity medicine and its links with the psychedelic world.

Tumor metabolism is mandatory for the proper adaptation of malignant cells to the microenvironment and the acquisition of crucial cellular skills supporting the systemic spread of cancer. Throughout this journey, the contribution of the gut microbiota to the bioavailability of nutrients supporting the bioenergetic and biosynthetic requirements of malignant cells is an issue. This review will focus on the role of cysteine as a coin that mediates the metabolic crosstalk between microbiota and cancer. The key points enclose the way cysteine can be made available by the microbiota, by degradation of more complex compounds or by de novo synthesis, in order to contribute to the enrichment of the colonic microenvironment as well to the increase of cysteine systemic bioavailability. In addition, the main metabolic pathways in cancer that rely on cysteine as a source of energy and biomass will be pointed out and how the interspecific relationship with the microbiota and its dynamics related to aging may be relevant points to explore, contributing to a better understanding of cancer biology.

In the human organism, several interspecific relationships are constantly in operation, which are established between the different species that make up the microbiota and the human cells of the various organs where it resides. These interspecific relationships are mainly symbiotic in which both partners benefit. This is the case in health, but in disease, there are still some doubts about the role of the microbiota in the pathophysiology, namely, in the context of cancer, at both the organ and systemic levels. Currently, new clues have been proposed, and several studies have been developed to determine the influence of microbiota in cancer initiation, progression, and therapy, as it is extensively reviewed (1– 7).

Metabolic adaptation in cancer is undoubtedly an essential requirement for the establishment, growth, and spread of a malignant neoplasm. Cellular plasticity is crucial for the adaptation of the tumor cell to the microenvironment of the organ where carcinogenesis occurs and to the emergence of stress conditions, such as drug exposure. Recent studies prove that cysteine metabolic circuits are a relevant component of the metabolic network, sustaining biosynthesis and bioenergetics and allowing chemoresistance (as reviewed in 8 – 10). This review intends to confront some of the most recent findings in the field of cysteine metabolism in cancer and the role of the intestinal microbiota in the dynamic balance of the control of cysteine bioavailability and its putative impact on the progression of oncological disease.
