Over the weekends I try to catch up on more diverse reading and sometimes come up with a list of stuff I want to get to during this time, but I also put together weekend reads usually on Fridays as a kind of TGIF on The Niche for the wider audience here. So here’s the weekend reads for this Friday the 13th including some wacky stuff at the end. Anti-Aging efforts got some play in the media including this LA Times piece. Here’s the …Read More

Can we humans grow healthy new brain cells as adults and during later aging? The answer to this question is a big deal because it could have major impact on aging. Those hoped-for new brain cells could keep our brains functionally younger. Who doesn’t want to slow down the aging of their brain, right? Slowing down aging of the brain via new cell growth more broadly would have major impacts on society. Researchers have gone back and forth on this over years. Fairly long …Read More

It’s stem cell day! Or more accurately, it is stem cell awareness day. It’s a good time to think about where our field stands and where we’ll be in 10 years. Below, I’ve outlined 10 for 10: 10 things to ponder about stem cells in a 10-year timeframe. Approved Therapies. How many new stem cell therapies will be approved as safe and effective in 10 years? I hope at least 10! These may include proven transformative regenerative medicine treatments for macular degeneration, Type 1 …Read More

A new Cell paper from Juan Carlos Izpisua Berlmonte’s group has made headlines about anti-aging across the globe because it suggests that the four core induced pluripotent stem cell (IPSC) factors use by Shinya Yamanaka to make IPSC can reverse aging. I’ve pasted the graphical abstract from the paper below and done a quick journal club style overview based on a quick skim of the paper. Some of the media headlines are rather dramatic on this story. For instance, in a story on it over at STAT …Read More

The transhumanism movement has been garnering attention lately for a variety of views including embracing aspects of heritable human genetic modification. Earlier this year I interviewed geneticist and transhumanist, George Church. In this post I interview molecular biophysicist and transhumanist Maria Konovalenko. She is the program coordinator at the Science for Life Extension Foundation. In addition she has a blog. Paul: Where does transhumanism stand today? Is it a growing movement? Who would you say are the top leaders in the movement? Konovalenko: If we …Read More

When it comes to anti-aging science, creepy meets cool with “young blood” in new blood mixing studies just published. The researchers report that blood from young animals literally makes older animals younger. That striking claim is made by both of two independent teams that published high-profile papers that just came out in Science and Nature Medicine.  One of the teams, led by Lee Rubin and Amy Wagers of Harvard, has further narrowed in on one specific factor in blood that may be particularly important called growth …Read More

Can Google’s new anti-aging company, Calico, have you Googling at age 140? Don’t sell your burial plot just yet. The idea of anti-aging has been around for a very long time and efforts to combat aging have spanned millennia largely without any success so Calico (apparently short for California Life Company, which sounds more like an insurance company to me) faces long odds. Note too that Calico cats are not known for any particular predisposition to long life. Hmmm. Note that you might find …Read More
