Can We Evolve Ourselves To Expand Beyond Human Potential?

Posted by in categories: bioengineering, biotech/medical, evolution, existential risks, genetics, human trajectories

At one time or another, we’ve all been encouraged to “maximize our potential.” In a recent interview, Academic and Entrepreneur Juan Enriquez said that mankind is making progress toward expanding beyond its potential. And the changes, he believes, could be profound.

To illustrate the process, Enriquez theorized what might happen if we were to bring Charles Darwin back to life and drop him in the middle of Trafalgar Square. As Darwin takes out his notebook and starts observing, Enriquez suggested he would likely see what might appear to be a different species. Since Darwin’s time, humans have grown taller, and with 1.5 billion obese people, larger. Darwin might also notice some other features too that many of us take for granted — there are more senior citizens, more people with all their teeth, a lot fewer wrinkles, and even some 70-year-olds running in marathons.

“There’s a whole series of morphologies that are just different about our bodies, but we don’t notice it. We don’t notice we’ve doubled the lifespan of humans in the last century,” Enriquez said. “We don’t notice how many more informations (sic) come into a brain in a single day versus what used to come in in a lifetime. So, across almost every part of humanity, there have been huge changes.”

Part of the difference that Darwin would see, Enriquez noted, is that natural selection no longer applies as strongly to life and death as it once did. Further, random gene mutations that led to some advantages kept getting passed down to generations and became part of the species. The largest difference, however, is our ongoing move toward intelligent design, he said.

Should We Create Superhumans? Q&A with Author James Rollins

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

Rollins, who has a Ph.D. in veterinary medicine, took some time to talk about genetic engineering, the future of humanity and the ethical limits of science.

(This Q&A has been edited for length and clarity.)

Live Science: A quote from “The Bone Labyrinth” reads, “Research today has become more about seeing if something can be done versus judging if it should. It’s knowledge for the sake of knowledge, regardless of the impact on the world.” Is that you speaking? Is that what you personally believe?

This Device Lets You Brew Your Own Drugs At Home

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

A machine prototype called Farma can let you manufacture your daily prescription of drugs right in your own home. Designed by MIT Media Lab graduate Will Patrick, the concept tech features a green cylinder and uses blue-green algae that’s genetically engineered to produce pharmaceutical drugs.


In the future, you might be able to skip the pharmacy and, instead, make your treatments along with your morning breakfast.

Genetic ‘intelligence networks’ discovered in the brain

Posted by in categories: genetics, neuroscience

Color-coded heatmap of gradient of expression of the M1 gene network, spanning fetal development to late adulthood and expressed in distinct cortical regions (listed on right, such as primary somatosensory cortex, S1C). Most of the genes in this network express in cortical regions (indicated by red), except for the V1C (primary visual cortex), STR (striatum), CBC (cerebellar cortex), and MD (mediodorsal nucleus of thalamus) brain areas.

Scientists from Imperial College London have identified two clusters (“gene networks”) of genes that are linked to human intelligence. Called M1 and M3, these gene networks appear to influence cognitive function, which includes memory, attention, processing speed and reasoning.

Importantly, the scientists have discovered that these two networks are likely to be under the control of master regulator switches. The researcher want to identify those switches and see if they can manipulate them, and ultimately find out if this knowledge of gene networks could allow for boosting cognitive function.

Pulsed laser light turns whole-brain activity on and off

By flashing high-frequency (40 to 100 pulses per second) optogenetic lasers at the brain’s thalamus, scientists were able to wake up sleeping rats and cause widespread brain activity. In contrast, flashing the laser at 10 pulses per second suppressed the activity of the brain’s sensory cortex and caused rats to enter a seizure-like state of unconsciousness.

“We hope to use this knowledge to develop better treatments for brain injuries and other neurological disorders,” said Jin Hyung Lee, Ph.D., assistant professor of neurology, neurosurgery, and bioengineering at Stanford University, and a senior author of the study, published in the open-access journal eLIFE.

Ethics on the near-future battlefield

US army’s report visualises augmented soldiers & killer robots.


The US Army’s recent report “Visualizing the Tactical Ground Battlefield in the Year 2050” describes a number of future war scenarios that raise vexing ethical dilemmas. Among the many tactical developments envisioned by the authors, a group of experts brought together by the US Army Research laboratory, three stand out as both plausible and fraught with moral challenges: augmented humans, directed-energy weapons, and autonomous killer robots. The first two technologies affect humans directly, and therefore present both military and medical ethical challenges. The third development, robots, would replace humans, and thus poses hard questions about implementing the law of war without any attending sense of justice.

Augmented humans. Drugs, brain-machine interfaces, neural prostheses, and genetic engineering are all technologies that may be used in the next few decades to enhance the fighting capability of soldiers, keep them alert, help them survive longer on less food, alleviate pain, and sharpen and strengthen their cognitive and physical capabilities. All raise serious ethical and bioethical difficulties.

Technology Will Save Our Future, According To Japanese SF Author Taiyo Fujii

Posted by in categories: augmented reality, engineering, genetics, security

I’ve been increasingly interested in translated science fiction novels, and one of the best ones that I picked up this year was Taiyo Fujii’s debut Gene Mapper.

Gene Mapper takes place in a future where augmented reality and genetic engineering is commonplace. When a freelance gene mapper named Hayashida finds that a project that he had worked on is collapsing, he believes that it’s being sabotaged. Determined to fix it, he travels to Vietnam where he finds that there’s more behind the problem than he initially thought.

You can read a tie-in story over on Lightspeed Magazine, ‘Violation of the TrueNet Security Act’.

Britain should lead way on genetically engineered babies, says Chief Scientific Adviser

Posted by in category: genetics

But at a conference in London yesterday, Sir Mark Walport, who advises the government on scientific matters, said he believed there were ‘circumstances’ in which the genetic editing of human embyros could be ‘acceptable’.
