Jeffrey Epstein Hoped to Seed Human Race With His DNA

Mr. Epstein’s vision reflected his longstanding fascination with what has become known as transhumanism: the science of improving the human population through technologies like genetic engineering and artificial intelligence. Critics have likened transhumanism to a modern-day version of eugenics, the discredited field of improving the human race through controlled breeding.
Mr. Epstein, the accused sex trafficker, was fascinated by eugenics. He told scientists and others of his vision of using his New Mexico ranch to impregnate women.

Japan approves first human-animal embryo experiments

But getting human cells to grow in another species is not easy. Nakauchi and colleagues announced at the 2018 American Association for the Advancement of Science meeting in Austin, Texas that they had put human iPS cells into sheep embryos that had been engineered not to produce a pancreas. But the hybrid embryos, grown for 28 days, contained very few human cells, and nothing resembling organs. This is probably because of the genetic distance between humans and sheep, says Nakauchi.
The research could eventually lead to new sources of organs for transplant, but ethical and technical hurdles need to be overcome.

‘Limitless Potential’ of Artificial Protein Ushers in New Era of ‘Smart’ Cell Therapies
Posted by Paul Battista in categories: bioengineering, biotech/medical, robotics/AI
Medicine has a “Goldilocks” problem. Many therapies are safe and effective only when administered at just the right time and in very precise doses – when given too early or too late, in too large or too small an amount, medicines can be ineffective or even harmful. But in many situations, doctors have no way of knowing when or how much to dispense.
Now, a team of bioengineers led by UC San Francisco’s Hana El-Samad, PhD, and the University of Washington’s David Baker, PhD, have devised a remarkable solution to this problem – “smart” cells that behave like tiny autonomous robots which, in the future, may be used to detect damage and disease, and deliver help at just the right time and in just the right amount.

First Human CRISPR Trial in the US Aims to Cure Inherited Blindness
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, genetics
Gene editing is advancing at a faster pace than most of us can keep up with. One significant recent announcement was gene editing tool CRISPR’s application to non-genetic diseases thanks to a new ability to edit single letters in RNA.
Even as CRISPR reaches milestones like this, scientists continue to find new uses for it to treat genetic conditions. The next one that will hit clinics is a CRISPR treatment for a form of blindness called Leber congenital amaurosis (LCA).
Having been approved by the FDA in December, the treatment will be the first of its kind to be trialed in the US.

Stanford team stimulates neurons to induce particular perceptions in mice’s minds
Posted by Quinn Sena in categories: bioengineering, biotech/medical, neuroscience
Hallucinations are spooky and, fortunately, fairly rare. But, a new study suggests, the real question isn’t so much why some people occasionally experience them. It’s why all of us aren’t hallucinating all the time.
In the study, Stanford University School of Medicine neuroscientists stimulated nerve cells in the visual cortex of mice to induce an illusory image in the animals’ minds. The scientists needed to stimulate a surprisingly small number of nerve cells, or neurons, in order to generate the perception, which caused the mice to behave in a particular way.
“Back in 2012, we had described the ability to control the activity of individually selected neurons in an awake, alert animal,” said Karl Deisseroth, MD, Ph.D., professor of bioengineering and of psychiatry and behavioral sciences. “Now, for the first time, we’ve been able to advance this capability to control multiple individually specified cells at once, and make an animal perceive something specific that in fact is not really there—and behave accordingly.”
