I Spent a Weekend With Cyborgs, and Now I Have an RFID Implant I Have No Idea What to Do With

Posted by in categories: biotech/medical, cyborgs

Jeffrey Tibbetts prepped for implantation and scrubbed in, methodically sudsing up to his elbows, scraping the dirt from under his fingernails and scouring his hands with a rough brush to render his body sterile before donning a pair of beige latex surgical gloves.

Behind him, a twentysomething tea barista in a black baseball cap waited pensively, his left ring finger exposed from under a surgical drape, a tourniquet wrapped tightly around it. For months, an implanted magnet had been uncomfortably bulging out of the side of Zac Shannon’s finger. Tibbetts picked up a scalpel and began cutting, gently scraping away at the flesh until the incision was deep enough to expose the magnet. With the very steady hands of a practiced surgeon, he pulled out the tiny hunk of metal.

Tibbetts plopped another magnet into the finger, sutured it shut, and removed the tourniquet. The small wound began to gush blood.

E. coli rewired to control growth as experts let them make proteins for medicine

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

Experts have equipped biotech workhorse bacteria with feedback control mechanism to balance growth with making protein products.

Medicines like insulin and interferon are manufactured using genetically engineered bacteria, such as E. coli. E. coli grow quickly and can be given DNA that instructs them to make proteins used in medicines and other materials.

However, the extra burden of producing new proteins hampers bacterial growth, which slows production. Solving this problem is an area of great interest for biotechnology and synthetic biology.

You Know That Romaine-Linked Outbreak? DNA Tech Is Fixing It

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

Whole genome sequencing is more precise than other methods, and it just keeps getting faster and cheaper. Joel Sevinsky, head of the Molecular Science Laboratory at the Colorado Department of Public Health and Environment (CDPHE), told the Associated Press his lab can sequence the genome of a suspected pathogen in less than 72 hours.

Whole genome sequencing is already helping researchers address food-borne outbreaks, including a 2017 salmonella outbreak that stretched across 21 states, and the current romaine outbreak.

Q&A: AI Could ‘Redesign’ the Drug Development Process

Posted by in categories: biotech/medical, robotics/AI

AI can discover new drugs because biology is messy and complex, not in spite of that fact, says Andrew Hopkins.

Goldenrod Extract has a Marginal Senolytic Effect in Cell Culture Study

Posted by in categories: biotech/medical, life extension

Today, we have a new study showing that a common, plant-based compound could help clear out unwanted senescent cells, which accumulate with age and produce inflammatory signals that drive age-related disease progression.

Taking out the trash

A new study has investigated a natural, plant-based compound for its ability to destroy senescent cells [1]. These cells accumulate with age due to the aging immune system becoming increasingly poor at removing them; this leads to a build-up of these cells and the secretions they produce, which cause chronic inflammation. These proinflammatory secretions are known as the senescence-associated secretory phenotype (SASP).

CGP Grey: The Fable of the Dragon-Tyrant

Posted by in categories: biotech/medical, life extension

CGP Grey has produced a new video, this time an animated version of Prof. Nick Bostrom’s “The Fable of the Dragon-Tyrant”. The fable is a powerful metaphor for aging and the acceptance mechanisms that have led humans to schedule their entire lives around its diktat.


There’s a good chance that ten or fifteen years from now, we’ll look back at this moment in history and realize that we were living through the beginning of a revolution, the first baby steps of what would eventually become a global movement. Maybe it’ll take longer, but just like it was for human flight, the unmistakable signs of the upcoming paradigm shift are all around us.

Scientists Get Their First Look at the Enzyme That Could Help Battle Aging

Posted by in categories: biotech/medical, life extension

The enzyme holds clues to a possible cure for aging or potential cancer therapies.

Janet Iwasa

Nothing in your body lasts forever. Every single cell in your body will die eventually, and eventually you’ll run out of replacements. When that happens, various parts of your body will stop working correctly, and at some point the whole thing will shut down. Aging happens to all of us, and there’s nothing we can do about it.

Deniers and Critics of AI Will Only Be Left Behind

Posted by in categories: biotech/medical, ethics, genetics, geopolitics, health, policy, robotics/AI, transhumanism

This month I’m participating in Cato Institute’s Cato Unbound discussion. Cato is one of the world’s leading think tanks. Here’s my new and second essay for the project:


Professor David D. Friedman sweeps aside my belief that religion may well dictate the development of AI and other radical transhumanist tech in the future. However, at the core of a broad swath of American society lies a fearful luddite tradition. Americans—including the U.S. Congress, where every member is religious—often base their life philosophies and work ethics on their faiths. Furthermore, a recent Pew study showed 7 in 10 Americans were worried about technology in people’s bodies and brains, even if it offered health benefits.

It rarely matters what point in American history innovation has come out. Anesthesia, vaccines, stem cells, and other breakthroughs have historically all battled to survive under pressure from conservatives and Christians. I believe that if formal religion had not impeded our natural secular progress as a nation over the last 250 years, we would have been much further along in terms of human evolution. Instead of discussing and arguing about our coming transhumanist future, we’d be living in it.
