These desktop gadgets should make DIY genetic engineering much easier.

Harvard bioethics specialist Glenn Cohen considers the complex question of whether humans should mix their genetic material with other animals to create chimeras.

In an epidsode of the dystopian near-future series, Black Mirror, a small, implantable device behind the ear grants the ability to remember, access, and replay every moment of your life in perfect detail, like a movie right before your eyes.

Theodore Berger, a biomedical engineer at the University of Southern California, can’t promise that level of perfect recall—perhaps for the better—but he is working on a memory prosthesis. The device, surgically implanted directly into the brain, mimics the function of a structure called the hippocampus by electrically stimulating the brain in a particular way to form memories—at least in rats and monkeys. And now, he’s testing one that could work in humans.

Berger’s device hinges on a theory about how the hippocampus transforms short-term memories, like where you deposited your keys, into long-term memories—so you can find them later. In his early experiments, he played a tone and then puffed air in a rabbit’s face, causing it to blink. Eventually, just playing the tone would make the rabbit blink, just like Pavlov’s famous salivating dogs. Berger recorded the hippocampus’ activity with electrodes, and as the rabbits learned to associate the tone with the air puff, patterns in those signals changed in a predictable way.

More on the cell circuited technology that will deprive cancer cells of oxygen.

Imagine having cells in your body that can actively repel cancer in a way that makes it theoretically impossible for you to suffer from it.

Researchers at the U.K.’s University of Southampton…have engineered cells with a so-called “built-in genetic circuit” capable of producing a molecule for inhibiting the ability of tumors to grow and survive in the body.

BMI implant leveraging AI.

You probably clicked on this article because the idea of using brain implants to allow artificial intelligence (AI) to read your brain sounds futuristic and fascinating. It is fascinating, but it’s not as futuristic as you might think. Before we start talking about brain implants and how to augment the human brain using AI, we need to put some context around human intelligence and why we might want to tinker with it.

I have been evangelizing this for a while and glad to see others chiming in.

London, Nov 26 (IANS) Researchers have engineered cells with a “built-in genetic circuit” that produces a molecule that impairs the ability of cancer cells to survive and grow in their low oxygen environment.

The genetic circuit produces the machinery necessary for the production of a compound that inhibits a protein which has a significant and critical role in the growth and survival of tumours.

A synthetic metabolic pathway developed by Tobias Erb and his colleagues at the Max Planck Institute for Terrestrial Microbiology in Marburg converts CO₂ from the atmosphere into organic matter more efficiently than plants are able to through photosynthesis. We asked the researcher what significance this process could have for climate protection, discussed the hurdles the research team had to overcome to achieve their goal, and looked at the new perspectives that synthetic biology opens up.

Does the synthetic metabolic pathway that fixes CO₂ now represent an effective means of curbing climate change?

Firstly, we are aiming to understand the fundamental biological and chemical principles of how CO₂ in gaseous form can be converted into organic molecules. Our primary motivation is not stopping climate change. We are seeking to develop atmospheric CO₂ as a source of carbon for the future using biological methods. Producing a CO2-neutral process or even one that removes CO₂ from the atmosphere and has a positive impact on the climate would be a fantastic secondary effect.

WASHINGTON – Scientists believe genetic engineering experiments have the potential to wipe out malaria and other illnesses that kill millions of people every year.

But they also acknowledge they could have unintended consequences that could be catastrophic.

So, over the next four years, the Pentagon’s Defense Advanced Research Projects Agency, dubbed DARPA, plans to develop a cleanup crew for engineered genes deemed harmful to the eco-system.

We’re only starting in this space.

Synthetic Biology (SynBio) includes a large field of applications. Within this area biochemists combine engineering concepts and techniques with biology to design new genes that produce a specific protein. When this protein is an enzyme, bacteria and yeast in which such a gene is implanted can produce specific chemicals through a fermentation process. A large and growing number of businesses is active in this field. This became apparent once again at the EFIB-conference in Glasgow, last October. The workshop was chaired by John Cumbers, founder of the American SynBioBeta, an internet-site dedicated to sharing information and news on synthetic biology.
