The Imminence of Transhuman Technologies

Posted by in categories: bioengineering, ethics, existential risks, genetics, health, innovation, neuroscience

Progress always seems to ride a slippery slope. Innovations generally bring a plethora of potential benefits and just as many dangers, the obvious and the hidden. Technologies that tamper with our biological constructs is well underway in the neuro- and biotech industries. Historically, innovations in medicine have usually been beneficial on the aggregate.

But these new breakthroughs go beyond preventing and healing pre-existing causes. Transhuman technologies hold the promise of enhancing who we are as individuals and potentially as an entire species, and the decisions surrounding these technologies are far from simple. Dr. Nayef Al-Rodhan, a philosopher, neuroscientist, and director of the Geneva Center for Security Policy, believes we should be acting now to prepare for the inevitable and the unpredictable ramifications.

Framing Human Motivation

Considering our mixed track record as a species in rolling out groundbreaking innovations, discussing and finding potential solutions to many of the hidden dangers, and obvious ones, seems more than reasonable. One of the more puzzling questions is, where do we begin to have a pragmatic conversation on the ethics of these technologies?

There are plenty of theories about what drive human decisions, not least because human morality is infinitely complex and our minds crave frames through which to make sense of chaos. Dr. Al-Rodhan has his own conception of what drives human motivations. He makes meaning using the lens of “5 P’s” – Power, Pride, Profit, Pleasure, and Permanence – which he posits drive human motivations. “This is my view, the foundation of my outlook…this perceived emotion of self interest drives our moral compass.”

Curing Alzheimer’s

Posted by in categories: biotech/medical, genetics, health, life extension, mobile phones, neuroscience, space

Dr Michael Fossel is a PhD and MD heading up telomerase research and therapy and has kindly written a blog article for Bioviva detailing the work both they and his company Telocyte are doing to fight back against Alzheimer’s.


How Alzheimer’s Can Be Prevented and Cured…

Michael Fossel, MD, PhD

As I said in my medical textbook on aging, “If age is a thief, then the greatest treasure we lose is ourselves.” We fear Alzheimer’s not simply because it takes away our health, but because it steals our souls.

The First Human Head Transplant Will Take Place in 2017

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

Italian neurosurgeon Sergio Canavero grabbed the world’s attention this past winter when he announced his plans to perform the first human head transplant. Many doubted that such an outrageous procedure would ever see the light of day. Now, Canavero has a date on the books.

Thirty-year-old Russian computer scientist Valery Spiridonov is set to become the world’s first head transplant patient in December 2017. Spiridonov suffers from a rare genetic muscle-wasting condition known as Werdnig-Hoffmann disease. There’s currently no known treatment.

As you might not want to imagine, the procedure will be filled with challenges and uncertainties. There’s the hair-raising possibility that the head will reject the body or vice versa. The spinal cord might not fuse properly. Even if everything goes well, there’s no telling whether Spiridonov’s mental capacities or personality will remain the same. He’s embarking on totally uncharted medical territory.

Gene Editing Is Now Cheap and Easy—and No One Is Prepared for the Consequences

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

In April 2015, a paper by Chinese scientists about their attempts to edit the DNA of a human embryo rocked the scientific world and set off a furious debate. Leading scientists warned that altering the human germ line without studying the consequences could have horrific consequences. Geneticists with good intentions could mistakenly engineer changes in DNA that generate dangerous mutations and cause painful deaths. Scientists — and countries — with less noble intentions could again try to build a race of superhumans.

Human DNA is, however, merely one of many commercial targets of ethical concern. The DNA of every single organism — every plant, every animal, every bacterium — is now fair game for genetic manipulation. We are entering an age of backyard synthetic biology that should worry everybody. And it is coming about because of CRISPRs: clustered regularly interspaced short palindromic repeats.

Discovered by scientists only a few years ago, CRISPRs are elements of an ancient system that protects bacteria and other single-celled organisms from viruses, acquiring immunity to them by incorporating genetic elements from the virus invaders. CRISPRs evolved over millions of years to trim pieces of genetic information from one genome and insert it into another. And this bacterial antiviral defense serves as an astonishingly cheap, simple, elegant way to quickly edit the DNA of any organism in the lab.

Controversial Philosopher Says Man And Machine Will Fuse Into One Being

Posted by in categories: biotech/medical, cyborgs, engineering, genetics, singularity

The human being — especially in so-called “advanced civilizations” — is the animal that molds itself into its own pet.


Peter Sloterdijk is Germany’s most controversial thinker and media theorist. He has dared to challenge long-established divisions in traditional philosophy of body and soul, subject and object, culture and nature. His 1999 lecture on “Regulations for the Human Park,” in which he argued that genetic engineering was a continuation of human striving for self-creation, stirred up a tempest in a country known for Nazi eugenics. At the same time, he himself has concluded that “the taming of man has failed” as civilization’s potential for barbarism has grown ever greater. His seminal books include “Critique of Cynical Reason” and his trilogy, “Spheres.”

At a recent Berggruen Center on Philosophy and Culture symposium on humans and technology at Cambridge University’s St. John’s School of Divinity, The WorldPost discussed with Sloterdijk the end of borders between humans and technology, the cloud, singularity and identity in the age of globalization.

The Future Of Health: Precision Medicine

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

You may have heard of precision medicine in the news, but what actually is it, and what could it mean for the future of healthcare?

In the past, medicine was geared for the masses and was applied to large numbers of people, on the basis of average effectiveness. If a particular substance was ineffective on 10% of the population, it could still pass through and be prescribed anyway. Before genomics, it was tricky to understand or postulate why people had such varied responses to medication, but now we have the right tools — things are changing.

While all humans have extremely similar genes in percentage terms, there are distinct differences in each of us that create our particular vulnerabilities and characteristics. We also respond differently to many treatments; a cure for one might be mediocre for another. This is particularly true for cancer. With the Precision Medicine Initiative taking off, taking into account genetics, lifestyle and environment is beginning to give us an edge — making medicine more accurate and effective.

World’s largest public stem cell bank inaugurated in California

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

California researchers opened the world’s largest publicly available stem cell bank Tuesday, which will aid in the search for cures for genetic diseases such as Alzheimer’s, epilepsy and autism.

Universities from around the state will contribute adult skin samples to the bank, while the Buck Institute for Research in Novato will store the material.

The Stem Cell Bank is funded through a $32 million grant awarded in 2013 by the California Institute for Regenerative Medicine, which itself was established in 2004 through voter approval of Proposition 71. That measure provided an initial $3 billion in state bonds to the institute.

DNA Division Can Slow To A Halt

Posted by in categories: biotech/medical, genetics

A key mystery of the DNA replication process has been unraveled by researchers from King Abdullah University of Science and Technology (KAUST).

Before a bacterium can divide, it must make a copy of its genetic material, the circular DNA molecules that resemble bunched rubber bands, through a process called DNA replication. In this process, the two strands of DNA making up the circular DNA molecule unwind and separate to become templates for generating new strands.

To ensure the process is well regulated, the bacterium has set a number of “roadblocks,” or termination sites on the DNA, to ensure the permanent stoppage of replication forks, Y-shaped structures formed between the strands as the DNA molecule splits.

Editing humanity

Posted by in categories: biotech/medical, genetics

THE genome is written in an alphabet of just four letters. Being able to read, study and compare DNA sequences for humans, and thousands of other species, has become routine. A new technology promises to make it possible to edit genetic information quickly and cheaply. This could correct terrible genetic defects that blight lives. It also heralds the distant prospect of parents building their children to order.

The technology is known as CRISPR-Cas9, or just CRISPR. It involves a piece of RNA, a chemical messenger, designed to target a section of DNA; and an enzyme, called a nuclease, that can snip unwanted genes out and paste new ones in. Other ways of editing DNA exist, but CRISPR holds the promise of doing so with unprecedented simplicity, speed and precision.

A new biologically inspired “injectable cryogel whole-cell cancer vaccine” combines patient-specific harvested cancer cells and immune-stimulating chemicals or biological molecules to help the body attack cancer. It has been developed by scientists at Harvard’s Wyss Institute and Dana-Farber Cancer Institute.

This new approach is simpler and more economical than other cancer cell transplantation therapies, which harvest tumor cells and then genetically engineer them to trigger immune responses once they are transplanted back into the patient’s body, the researchers say.
