How DIY biohacking will change society

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

Imagine a scientist experimenting on her own genes from her kitchen, rather than going to a physician, because she wants to cure a medical ailment. Another “do-it-yourself” scientist across the country extracts DNA samples from plants to figure out how they affect its growth.

DIY biohacking is a relatively new phenomenon in which scientists (typically those with an interest in genetic engineering) want to take biology experimentation outside of the lab or classroom. Currently, it’s mostly used for medical purposes, but the future of DIY biohacking could look a lot different. So we asked four experts a simple question: By the year 2040, what will be the gene most edited via DIY biohacking?

Scientists discover nature’s algorithm for intelligence

Posted by in categories: biotech/medical, genetics, information science, mathematics, neuroscience

But if there is some kind of unifying computational principle governing our grey matter, what is it? Dr. Tsien has studied this for over a decade, and he believes he’s found the answer in something called the Theory of Connectivity.

“Many people have long speculated that there has to be a basic design principle from which intelligence originates and the brain evolves, like how the double helix of DNA and genetic codes are universal for every organism,” Tsien said. “We present evidence that the brain may operate on an amazingly simple mathematical logic.”

The Theory of Connectivity holds that a simple algorithm, called a power-of-two-based permutation taking the form of n=2i-1 can be used to explain the circuitry of the brain. To unpack the formula, let’s define a few key concepts from the theory of connectivity, specifically the idea of a neuronal clique. A neuronal clique is a group of neurons which “fire together” and cluster into functional connectivity motifs, or FCMs, which the brain uses to recognize specific patterns or ideas. One can liken it to branches on a tree, with the neuronal clique being the smallest unit of connectivity, a mere twig, which when combined with other cliques, link up to form an FCM. The more complex the idea being represented in the brain, the more convoluted the FCM. The n in n=2i-1 specifies the number of neuronal cliques that will fire in response to a given input, i.

Bible says Canaanites were wiped out by Israelites but scientists just found their descendants living in Lebanon

Posted by in categories: biotech/medical, genetics

It is a command that led the leading atheist Richard Dawkins to claim that the God of the Old Testament was “a vindictive, bloodthirsty ethnic cleanser … a genocidal … megalomaniacal, sadomasochistic, capriciously malevolent bully”.

For God had ordered the Israelites to slaughter the apparently sinful Canaanites, saying: “You shall not leave alive anything that breathes. But you shall utterly destroy them.” And, according to the Bible, they did just that.

However, a new genetic study has found that the Canaanites actually managed to survive this purge of their traditional homeland, passing on their DNA over the centuries to their numerous descendants in modern-day Lebanon.

New Study Suggests Previous Concerns about CRISPR Safety are Questionable

Posted by in categories: bioengineering, biotech/medical, food, genetics, life extension

Gene editing aims to make precise changes to the target DNA whilst avoiding altering other parts of the DNA. The objective of this is to remove undesirable genetic traits and introduce desirable changes in both plants and animals. For example, it could be used to make crops more drought resistant, prevent or cure inherited genetic disorders or even treat age-related diseases.

As some of you may recall, back in May a study was published which claimed that the groundbreaking gene editing technique CRISPR caused thousands of off target and potentially dangerous mutations[1]. The authors of the paper called for regulators to investigate the safety of the technique, a move that could potentially set back research years if not decades.

This publication has been widely blasted by the research community due to serious questions about the study design being raised. One of the problems with this original paper was that it involved only three mice, this is an extremely poor number to make the kind of conclusions the paper did. There have been calls for the paper to be withdrawn and critical responses to the study.

New Cancer Vaccine Shows Promising Results in Human Clinical Trial

Posted by in categories: biotech/medical, genetics, life extension

Customized cancer vaccines that match the unique genetic makeup of individual tumors have just passed phase 1 trials.


Cancer is predominantly a disease of aging caused by genomic instability. Finding effective ways to prevent and treat cancer is therefore of great interest to those working in the field of aging research as well as those working in oncology.

Therapies that target combinations of neoantigens, distinctive markers on the surface of cancer cells that the immune system learns to identify, is one potential approach to treating cancer. These neoantigen combinations vary between one patient and another and this is the focus of a new study which we will talk about today[1].

Zoltan Istvan: the poster boy for immortality

Posted by in categories: cyborgs, economics, genetics, life extension, open access, robotics/AI, transhumanism

I’m really excited to announce a 5-page feature spread on my #transhumanism work and Libertarian Governor campaign in today’s Times of London Magazine, one of England’s oldest and largest papers. There’s a paywall for digital but I think you can get two articles free without registering. If you have access to the print, it’s in the magazine:


Zoltan Istvan is launching his campaign to become Libertarian governor of California with two signature policies. First, he’ll eliminate poverty with a universal basic income that will guarantee $5,000 (£3,800) per month for every Californian household for ever. (He’ll do this without raising taxes a dime, he promises.) The next item in his in-tray is eliminating death. He intends to divert trillions of dollars into life-extending technologies – robotic hearts, artificial exoskeletons, genetic editing, bionic limbs and so on – in the hope that each Californian man, woman and AI (artificial intelligence) will eventually be able to upload their consciousness to the Cloud and experience digital eternity.

“What we can experience as a human being is going to be dramatically different within two decades,” he…

Building the Safe Genes Toolkit

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

DARPA created the Safe Genes program to gain a fundamental understanding of how gene editing technologies function; devise means to safely, responsibly, and predictably harness them for beneficial ends; and address potential health and security concerns related to their accidental or intentional misuse. Today, DARPA announced awards to seven teams that will pursue that mission, led by: The Broad Institute of MIT and Harvard; Harvard Medical School; Massachusetts General Hospital; Massachusetts Institute of Technology; North Carolina State University; University of California, Berkeley; and University of California, Riverside. DARPA plans to invest $65 million in Safe Genes over the next four years as these teams work to collect empirical data and develop a suite of versatile tools that can be applied independently or in combination to support bio-innovation and combat bio-threats.

Gene editing technologies have captured increasing attention from healthcare professionals, policymakers, and community leaders in recent years for their potential to selectively disable cancerous cells in the body, control populations of disease-spreading mosquitos, and defend native flora and fauna against invasive species, among other uses. The potential national security applications and implications of these technologies are equally profound, including protection of troops against infectious disease, mitigation of threats posed by irresponsible or nefarious use of biological technologies, and enhanced development of new resources derived from synthetic biology, such as novel chemicals, materials, and coatings with useful, unique properties.

Achieving such ambitious goals, however, will require more complete knowledge about how gene editors, and derivative technologies including gene drives, function at various physical and temporal scales under different environmental conditions, across multiple generations of an organism. In parallel, demonstrating the ability to precisely control gene edits, turning them on and off under certain conditions or even reversing their effects entirely, will be paramount to translation of these tools to practical applications. By establishing empirical foundations and removing lingering unknowns through laboratory-based demonstrations, the Safe Genes teams will work to substantially minimize the risks inherent in such powerful tools.
