What makes the spin flip over?

Posted by in categories: nanotechnology, quantum physics

The Einstein-de-Haas effect shows that magnetism results from the angular momentum of electrons and is considered as the macroscopic evidence of electron spin. Researchers at Karlsruhe Institute of Technology (KIT) and at the Institut NÉEL at the CNRS in Grenoble were the first to investigate this effect for an individual spin and formulated it as the new “Quantum Einstein-de-Haas effect”. In Nature Communications, they report on their work (“Quantum Einstein-de Haas effect”).

Engineering a better biofuel

Posted by in categories: engineering, sustainability

The often-maligned E. coli bacteria has powerhouse potential: in the lab, it has the ability to crank out fuels, pharmaceuticals and other useful products at a rapid rate. A research team has discovered a new way to remove a major stumbling block in the process, and boost biofuel production from E. coli.

Nanoparticle delivers cancer drugs to tumor blood vessels

Posted by in categories: biotech/medical, engineering

In a set of studies in mice bearing human tumors, nanoparticles designed to bind to a protein called P-selectin successfully delivered both chemotherapy drugs and targeted therapies to tumor blood vessels. Targeting the blood vessels improved the delivery of drugs to tumor tissue, causing the tumors to shrink and improving how long the mice lived.

A tumor’s blood vessels can serve as a barrier to engineered drug-delivery systems like nanoparticles, which may not be able to cross the blood vessel wall. However, the same blood vessels may express proteins—such as P-selectin—that researchers can potentially exploit, by engineering their nanoparticles to recognize and latch onto those proteins, which enables them to reach the tumor.

AI for President

Posted by in categories: engineering, geopolitics, robotics/AI, transhumanism

This is a comprehensive and critical write-up on some of my policies by some leading researchers and thinkers. It’s from the magazine website of the IEEE, the world’s largest professional organization devoted to engineering and the applied sciences. Naturally, people in the field of science and engineering are some of the most difficult to please, since they are such critical thinkers (which is precisely why I like them so much):


When a transhumanist runs for president, what does that mean for society?

Life Extension: How to Reach a Societal Turning Point — Talk b…

Posted by in categories: innovation, life extension

Keith Comito from LEAF/Lifespan.io talking about the need for a unified call to action and how we have reached a turning point in the life extension movement.


In this talk LEAF President Keith Comito explains how initatives like Lifespan.io (https://www.lifespan.io/campaigns/sens-control-alt-delete-cancer/) fit into the broader goal of building a grassroots movement in support of life extension, with the eventual aim of effecting massive societial change on the issue. If you are looking for a deep dive into the full scope of life extension advocacy, from the dawn of history to current breakthroughs and opportunities, this is it.

This presentation is part of the Designing New Advances conference held by the Institute of Exponential Sciences in the Netherlands, orchestrated by Demian Hoed and Lotte van Noort.
