“Early life strongly influences DNA methylation variation across the lifespan, and the effects are stronger for heritable sites and sites biologically relevant to the regulation of gene expression. Early life could affect late-life health through influencing DNA methylation.” | learn more

“Worker honeybees of the South African variety can clone themselves, one of whom did so, many millions of times, for 30 years, according to a recent study published in the journal Proceedings of the Royal Society B.” | learn more
“[R]esearchers studying mice have worked out how bacteria in the mammalian gut can ping the brain to regulate an animal’s appetite and body temperature—and it involves the same molecular pathway the immune system uses to detect bacterial pathogens.” | learn more
I not-so-boldly predict the hardware we have access to as consumers will continue to get better and cheaper. “The device is about the size of a stack of six quarters. It is applied to the skin through a Velcro-like patch […]
This is the fourth and final part of the “What’s different” series. It has been a very interesting read. It paints a picture of an exciting time for humanity. One excerpt that really grabbed me about AI and the power […]
One interesting element here is that the researchers can’t figure out how this works. They even tried obscuring things they thought were indicators like bone density, but that didn’t stop the AI. | learn more
“Most evidence linking the gut microbiota to brain phenotypes and behaviors is from animal models. These preclinical studies have informed strategies for further analyses and interventions in humans, but more rigorous human studies are needed to distinguish causality from association.” | learn […]
“The effects of the plasmalogen supplement on learning and memory were tested by training mice to use a Morris water maze — a pool of water that contains a platform that serves as a resting area.” | learn more
You might remember that young blood transfusions rejuvenates old animals, and that actually simply diluting the old plasma does the trick. Now researchers have found a new way to help older mice regain memory by swapping CSF fluid. “CSF is a clear […]
