Negative Time is Real, Physicists Confirm. Kind Of
Build your problem solving skills with Brilliant! First 30 days are free and 20% off the annual premium subscription when you use our link ➜ https://brilliant.org/sabine.
In a new paper, a group of physicists claims to have confirmed the existence of “negative time.” I had never heard of this, but I had a look at the paper. And I think I have figured it out.

Longevity Scientist: Aging Will Soon Be Treatable But Immortality Is Not the Goal
Can we really slow aging or even reverse it?
Aging is no longer viewed as an untouchable part of life. According to Eric Verdin, scientists are beginning to treat aging itself as a biological process that can be slowed and potentially reversed.
In this episode, Eric explains why longevity research is entering a new era. He discusses how AI, women’s health, metabolic therapies, and partial reprogramming are reshaping medicine. He highlights GLP-1 drugs as one of the most promising tools today and explains how resetting cells to a younger state may one day restore function in aging tissues.
He also shares the most effective strategies available right now: exercise, sleep, nutrition, mental stimulation, and social connection. While supplements like Creatine may help, Eric stresses that lifestyle remains the foundation of long-term health.
Eric Verdin is a physician-scientist and CEO of the Buck Institute for Research on Aging, where he leads research focused on extending human healthspan.
What You’ll Learn.
AI generates full battery electrolyte recipes, matching top lithium metal battery performance
Battery electrolytes aren’t just one chemical, but a complex mixture of salts, solvents, and additives interacting and reacting with each other. Artificial intelligence has made great headway in helping select ideal materials to go into that chemical soup. But a team from the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) is using AI to generate the entire formulation, balancing the complicated tradeoffs and interactions that go into the electrolytes that make batteries possible.
The research is published in JACS Au. It is the next step in the Amanchukwu Lab’s ongoing development of an AI for battery work, ElectrolyteGPT.
“Next-generation battery electrolytes must meet multiple, often conflicting property requirements,” said first author Jaemin Kim. “With the model’s capability of generating outputs under diverse conditions, ElectrolyteGPT is able to generate novel candidates satisfying the desired properties simultaneously.”
Chris Hables Gray on AI and the Singularity: We Need Strong Citizenship!
In 2013, I interviewed a man who studies cyborgs and war for a living.
Somewhere in that conversation, Prof. Chris Hables Gray predicted a global pandemic. I chimed in that it would most likely stem from a bird flu outbreak.
We were both right. Neither of us wanted to be.
That was six years before COVID. And here we are in 2026, watching H5N1 headlines pile up again.
The point was never the prediction. The point was what he said we should do about it.
Chris did not pitch a gadget. He did not sell a forecast. He argued that surviving the century is not a technology problem; it is a citizenship problem.
How swarms of tiny light-controlled robots could revolutionize wound care
Having a swarm of microbots moving across your body may sound like the stuff of a horror movie, but it could actually be the future of targeted drug delivery and advanced wound healing. Scientists have developed a way to use blue and red light as a remote control to assemble and disperse swarms of biohybrid microrobots that could one day transform how we treat injuries.
Details of the research are in a paper published in the journal Science Advances.
The microrobots come in two parts. The first is a living green microalga called Chlamydomonas reinhardtii (CR), which uses two tail-like structures (flagella) to swim through aquatic environments and respond to light.
Is Transhumanism the Great Filter?
An exploration of the question of whether transhumanism, and the analogue in alien civilizations is in fact the great filter.
