The Blood of Exceptionally Long-Lived People Shows Key Differences
Posted by Paul Battista in categories: biotech/medical, genetics, life extension
Centenarians, once considered rare, have become commonplace. Indeed, they are the fastest-growing demographic group of the world’s population, with numbers roughly doubling every ten years since the 1970s.
How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and wrote about the ageing process over 2,300 years ago.
The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however. It involves unravelling the complex interplay of genetic predisposition and lifestyle factors and how they interact throughout a person’s life.

“Hubbard Excitons” — Caltech Physics Discovery Could Lead to Incredible New Technologies
Posted by Paul Battista in categories: computing, physics, solar power, space, sustainability
Caltech researchers have discovered Hubbard excitons, which are excitons bound magnetically, offering new avenues for exciton-based technological applications.
In art, the negative space in a painting can be just as important as the painting itself. Something similar is true in insulating materials, where the empty spaces left behind by missing electrons play a crucial role in determining the material’s properties. When a negatively charged electron is excited by light, it leaves behind a positive hole. Because the hole and the electron are oppositely charged, they are attracted to each other and form a bond. The resulting pair, which is short-lived, is known as an exciton [pronounced exit-tawn].
Excitons are integral to many technologies, such as solar panels, photodetectors, and sensors. They are also a key part of light-emitting diodes found in televisions and digital display screens. In most cases, the exciton pairs are bound by electrical, or electrostatic, forces, also known as Coulomb interactions.

In the six months since FLI published its open letter calling for a pause on giant AI experiments, we have seen overwhelming expert and public concern about the out-of-control AI arms race — but no slowdown. In this video, we call for U.S. lawmakers to step in, and explore the policy solutions necessary to steer this powerful technology to benefit humanity.
