DARPA’s Safe Genes program aims to build a biosafety and biosecurity toolkit to reduce potential risks and encourage innovation in the field of genome editing

The Safe Genes program could help unlock the potential of advanced gene editing technologies by developing a set of tools to address potential risks of this rapidly advancing field. The Safe Genes program envisions addressing key safety gaps by using those tools to restrict or reverse the propagation of engineered genetic constructs.

“Gene editing holds incredible promise to advance the biological sciences, but right now responsible actors are constrained by the number of unknowns and a lack of controls,” said Renee Wegrzyn, DARPA program manager. “DARPA wants to develop controls for gene editing and derivative technologies to support responsible research and defend against irresponsible actors who might intentionally or accidentally release modified organisms.”

Synthetic human lung cells possibly the best method for new drug testing.

Scientists are putting human cells through micro-obstacle courses designed to replicate the mechanics inside our bodies and better test drug effectiveness.

Making a splash? Engineers have created metallic nanofish that are inspired by the swimming style of real fish, and could be used to carry drugs to specific sites of the body.

We are entering an era of directed design in which we will expand the limited notion that biology is only the ‘study of life and living things’ and see biology as the ultimate distributed, manufacturing platform (as Stanford bioengineer, Drew Endy, often says). This new mode of manufacturing will offer us unrivaled personalization and functionality.

New foods. New fuels. New materials. New drugs.

We’re already taking our first steps in this direction. Joule Unlimited has engineered bacteria to convert CO₂ into fuels in a single-step, continuous process. Others are engineering yeast to produce artemisinin — a potent anti-malarial compound used by millions of people globally. Still other microbes are being reprogrammed to produce industrial ingredients, like those used in synthetic rubber.

New research suggests that nerve cells may be able to repair themselves by mobilizing mitochondria by removing a certain protein in cells. This may help combat neurological diseases such as Alzheimer’s in the near future.

The Mitochondria is the powerhouse of the cell. We all know that. It causes reactions that generate adenosine triphosphate (ATP), a source of chemical energy in a cell. A typical animal cell contains 1000 to 2000 mitochondria. Yet, that’s not all we learned in high school biology. Remember that neurons or nerve cells do not have the ability to repair themselves once damaged? Well, these two facts have stirred quite a bit of interest.

Scientists have found out that nerve cell regeneration is possible. Researchers from National Institute of Neurological Disorders and Stroke in the US restored mitochondrial mobility in a group of mice and observed regeneration of nerve cells.

A man left paralyzed from a spinal cord injury has regained movement in his arms and hands as a result of a novel stem cell treatment.

Model of the human genome.

A special nutrient must be fed to these bacteria or else they die off. Unless they find this selfsame nutrient in the environment, which Church says is unlikely, they would not be able to survive. Another fail-safe is a special barrier which has been erected to make it impossible for the bacteria to mate or reproduce, outside of the lab. But other experts wonder how “unbeatable” Church’s fail-safe’s actually are. Carr says that instead of discussing these measures as foolproof, we should be framing it in degrees of risk.

The next step is further testing of the artificial genes that have been made. Afterward, Church and colleagues will take this same genome and produce an entirely new organism with it. Since DNA is the essential blueprint for almost all life on earth, being able to rewrite it could give humans an almost god-like power over it. That capability is perhaps decades away. Even so, combined with gene editing and gene modification, and the idea of a race of super humans is not outside the realm of possibility.

Medical supply transportation is a serious problem in remote regions, where it may take weeks to transport a vaccine where it’s most needed. But a British student has developed a simple device that might help get supplies where they need to go and save millions of lives in the process.

Will Broadway of Loughborough University created the tank as a way to extend the life of fragile medical supplies, like vaccines, samples, and organs.

The device uses a simple ammonia reaction that creates a cooling effect when charged. It can keep vaccines within a stable temperature realm for up to 30 days. While it’s currently designed for vaccines, Broadway next wants to make it transport organs and tissues to people in need.

Ava Winery’s first public taste test didn’t exactly go well. Two reporters on camera at New Scientist compared the biotech startup’s artificial wine with a glass of the Moscato D’Asti that it was based on. They complained that the fake wine had too little color, too little viscosity, and an unpleasant plastic smell.

But that was May, and this is September, and Ava is already bragging about making huge improvements in its product, to the point where it is all but indistinguishable from fermented grape juice, and looking ahead to how it’s going to change the world.

“What we have done since then is leaps and bounds beyond what they were able to taste back in May,” co-founder Alec Lee says. “Now we’re at the point where about 90% of people fail out blind taste test.”
