Would you want to alter your future children’s genes to make them smarter, stronger or better-looking? As the state of the science brings prospects like these closer to reality, an international debate has been raging over the ethics of enhancing human capacities with biotechnologies such as so-called smart pills, brain implants and gene editing. This discussion has only intensified in the past year with the advent of the CRISPR-cas9 gene editing tool, which raises the specter of tinkering with our DNA to improve traits like intelligence, athleticism and even moral reasoning.

Researchers at the University of Washington in Seattle say that we need to act fast to implement a privacy and security framework to prevent our brain signals from being used against us before the technology really takes off…

Brain-computer interfaces offer new applications for our brain signals—and a new vector for security and privacy violations.

Neuroscientist Andrew B. Newberg provides the answer.

Prior to your study, how much was known about the way brain circuits develop? How has your recent study advanced our understanding?

There’s a tremendous amount known about brain circuit development. Our work was inspired by experiments that were done over 50 years ago by scientists at Harvard University, Hubel and Wiesel. They received a Nobel Prize for their work and have inspired many additional experiments over the last 50 or 60 years.

Indeed, if we set ethical and safety objections aside, genetic enhancement has the potential to bring about significant national advantages. Even marginal increases in intelligence via gene editing could have significant effects on a nation’s economic growth. Certain genes could give some athletes an edge in intense international competitions. Other genes may have an effect on violent tendencies, suggesting genetic engineering could reduce crime rates.

We may soon be able to edit people’s DNA to cure diseases like cancer, but will this lead to designer babies? If so, bioethicist G Owen Schaefer argues that China will lead the way.

University of California, Berkeley engineers have designed and built millimeter-scale device wireless, batteryless “neural dust” sensors and implanted them in muscles and peripheral nerves of rats to make in vivo electrophysiological recordings.

I have reported on this threat for a very long time as we see more BMI technology advance. However, one are where things could drastically reduce hacking and breeches is the migration to a Quantum based net and infrastructure.

Cyberthieves might be mining personal information from your brainwaves at this very moment.

MIT engineers have developed a microfluidic device that replicates the neuromuscular junction—the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and a small set of motor neurons. Researchers can influence and observe the interactions between the two, within a realistic, three-dimensional matrix.

The researchers genetically modified the neurons in the device to respond to light. By shining light directly on the neurons, they can precisely stimulate these cells, which in turn send signals to excite the muscle fiber. The researchers also measured the force the muscle exerts within the device as it twitches or contracts in response.

The team’s results, published online today in Science Advances, may help scientists understand and identify drugs to treat amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig’s disease, as well as other neuromuscular-related conditions.
