Laser mining – the light at the end of the tunnel?

Posted by in categories: chemistry, engineering, government

Laser mining would allow for a no explosive option and not need huge machines increasing output as well. Also lasers could make more precise cuts rather than blades which would never get dull.


The application of the “Graduated Optical Colimator” (GOC) for the mining industry consists of a one-kilowatt optical power fiber laser to selectively spall igneous geological formations containing narrow veins of precious metals.

Packaging-free design enables microbattery to store four times the energy

Posted by in categories: chemistry, energy, food

Engineers at the University of Pennsylvania have found a new way to build and package microbatteries that drastically improve energy and power density even at the smallest sizes. They developed a new kind of current collector and cathode that increases the fraction of materials that store energy while simultaneously serving as a protective shell. This reduces the need for non-conductive packaging that normally protects a battery’s sensitive internal chemicals.


It weighs the same as two grains of rice but has the energy density of a much larger, heavier battery.

This 1,992 paper was included on best-selling CDR World Philosophy compilation (before internet) and I claim some credit for circulated it and popularising the “Transhuman sidetrack”

Posted by in categories: chemistry, cryonics, ethics, existential risks, law, life extension, robotics/AI, transhumanism

Since 1,988 and formation of the Posthuman Movement, and articles by early adopters like Max Moore were a sign our message was being received — although I always argued on various Extropian & Transhuman bulletin boards & Yahoo groups &c that “Trans” was a redundant middle and we should move straight to Posthuman, now armed with the new MVT knowledge (also figures on the CDR). There will be a new edition of World Philosophy, the first this millennium, to coincided with various Posthuman University events later this year. Here is the text:

THE EXTROPIAN PRINCIPLES V. 2.01 August 7 1992.

Max More Executive Director, Extropy Institute.

Mutation-mapping tool could yield stronger COVID boosters, universal vaccines

Posted by in categories: bioengineering, biotech/medical, chemistry

Researchers at CU Boulder have developed a platform which can quickly identify common mutations on the SARS-CoV-2 virus that allow it to escape antibodies and infect cells.

Published today in Cell Reports, the research marks a major step toward successfully developing a universal vaccine for not only COVID-19, but also potentially for influenza, HIV and other deadly global viruses.

“We’ve developed a predictive tool that can tell you ahead of time which antibodies are going to be effective against circulating strains of virus,” said lead author Timothy Whitehead, associate professor of chemical and biological engineering. “But the implications for this technology are more profound: If you can predict what the variants will be in a given season, you could get vaccinated to match the sequence that will occur and short-circuit this seasonal variation.”

Sunscreen Concerns Escalate as Another Potential Carcinogen Found

Posted by in categories: biotech/medical, chemistry, health

Researchers asked U.S. regulators to pull some sunscreens from the market, including brands such as Coppertone, Banana Boat and Neutrogena, saying they’ve found evidence of a potential carcinogen.

Scientists petitioned the Food and Drug Administration to remove from sale all sunscreens containing the active ingredient octocrylene. Products made with the chemical may contain benzophenone, a suspected carcinogen that also can interfere with key hormones and reproductive organs, according to a group led by Craig Downs, executive director of the nonprofit Haereticus Environmental Laboratory that studies risks to health and the environment.

MIT Researchers Devised a Way To Program Memories Into Bacterial Cells

Posted by in categories: biotech/medical, chemistry, engineering

For several years, Lu’s lab has been working on ways to use DNA to store information such as memory of cellular events. In 2,014 he and Farzadfard developed a way to employ bacteria as a “genomic tape recorder,” engineering E. coli to store long-term memories of events such as a chemical exposure.


Technique for editing bacterial genomes can record interactions between cells, may offer a way to edit genes in the human microbiome.

Nutritional Supplements Could Help Treat PTSD

Posted by in categories: biotech/medical, chemistry, genetics, neuroscience

Since DNMT3A increases DNA methylation, the researchers used a natural product that donates methyl groups S-adenosylmethionine (SAMe) and to activate the retinoic acid receptor they treated the animals with vitamin A. They found that combined treatment with the methyl donor SAM and retinoic acid reversed PTSD-like behaviors.


Summary: Combining two natural products that modulate the epigenome, researchers believe they have identified a feasible approach to reversing symptoms of PTSD in animal models that could be effective in humans.
