Startups around the world are racing to become the globe’s premier source of “cultured meat.”

EXCLUSIVE: STEM cells are being used to regrow damaged knee cartilage in world-first Melbourne trials it is hoped will make many joint replacements and other surgery unnecessary.

Thanks to the cocktail of drugs that make up antiretroviral therapy, HIV is no longer a death sentence. But there are downsides to antiretroviral therapy—taking the treatment for many years is expensive, increases drug resistance, and could cause adverse reactions in a patient. And, because the virus stays in reservoirs in the body, the disease can continue to progress in patients if they stop taking their medication.

Now a team of German researchers has found an enzyme that can “cut” the viral DNA out of a cell’s genetic code, which could eradicate the virus from a patient’s body altogether. The proof-of-concept study, published this week in Nature Biotechnology and reported by Ars Technica, was done in mice, but the researchers believe that their conclusions show that this DNA-snipping enzyme could be used in clinical practice. And if it can cut HIV’s genetic code out of a patient’s body, the technique could be a cure for the disease.

The researchers created the DNA-snipping enzyme called Brec1 using directed evolution, an engineering technique that mimics proteins’ natural evolution process. They programmed the enzyme to cut DNA on either side of a sequence characteristic of HIV—a difficult task since the DNA of organisms and of the virus itself mutates often. Still, the researchers identified a well-conserved sequence, then they tested how reliably the enzyme could snip out that sequence in cells taken from HIV-positive patients, in bacteria, and in mice infected with the human form of HIV. After a number of tweaks, Brec1 would cut only that sequence of DNA, patching up the cell’s genetic code once the HIV sequence was cleaved out. After 21 weeks, the cells treated with Brec1 showed no signs of HIV.

I fully support this only when the net and infrastructure is secured from hackers.

Artificial intelligence should be used to provide children with one-to-one tutoring to improve their learning and monitor their well-being, academics have argued.

One-to-one tutoring has long been thought the most-effective approach to teaching but would be too expensive to provide for all students.

I agree 100% with this report by former pentagon official on AI systems involving missiles.

A new report written by a former Pentagon official who helped establish United States policy on autonomous weapons argues that such weapons could be uncontrollable in real-world environments where they are subject to design failure as well as hacking, spoofing and manipulation by adversaries.

In recent years, low-cost sensors and new artificial intelligence technologies have made it increasingly practical to design weapons systems that make killing decisions without human intervention. The specter of so-called killer robots has touched off an international protest movement and a debate within the United Nations about limiting the development and deployment of such systems.

What can be better than to go head to head against cyber attacks, let computer have a mind of their own and protect themselves? The executive producer of CBS hit show, Scorpion, and the CEO of Scorpion Computer Services, Walter O’Brien says that it not only is possible, but can be the only solution to stop such attacks.

@tferriss loved the Walter O’ Brien podcast. But, did you pick up on any issues with his story? https://t.co/jf8Gm2Ls1Y

Vanna Belton from Baltimore has been blind for more than five years, but after undergoing surgery where stem cells extracted from her bone marrow were injected into her right eye’s retina and left eye’s optic nerve, she has regained some of her sight.

“When I realised I could see the license plates, we started walking around the neighbourhood reading them,” she told the Baltimore Sun, adding that for the first time since 2009, she’s been able to navigate her way around without a cane.

While Belton’s recovery is certainly remarkable, it’s also incredibly perplexing. The doctor who performed the stem cell treatment, ophthalmologist Jeffrey N. Weiss, cut so many corners to get her and 277 other patients into surgery, even he can’t explain why it works.
