Genomic instability (mutations) has been suggested as being one of the primary hallmarks of aging and this research might support that idea. Researchers at John Hopkins report that around 66% of mutations in cancer cells are due to random errors with environment/lifestyle contributing 29% and 5% inherited.

“That finding challenges the common wisdom that cancer is the product of heredity and the environment. “There’s a third cause and this cause of mutations is a major cause,” says cancer geneticist Bert Vogelstein.”

“Such random mutations build up over time and help explain why cancer strikes older people more often. Knowing that the enemy will strike from within even when people protect themselves against external threats indicates that early cancer detection and treatment deserve greater attention than they have previously gotten, Vogelstein says.”

The team tested their device on a prosthetic hand. When the skin patches on the skin were enabled, the prosthetic could touch and grab soft objects like a normal hand. But when the skin was not turned on, the hand crushed the objects.

The skin requires just 20 nanowatts of power per square centimeter, according to the paper. Right now, the energy captured by the photovoltaic cells has to be used immediately, but the team has another prototype in development that includes flexible supercapacitors to store excess energy.

Fasting might help T1 diabetics according to new research.

Periodic fasting has long been demonstrated to have beneficial effects on autoimmune disorders, cancer prevention and treatments, cardiovascular disease and a myriad of other ailments. This most recent paper by Cheng et al. may add the treatment of Type 1 diabetes to that list[1]. If successful in humans it has the potential to reverse some or most of the loss of insulin producing cells within the pancreas. Just as remarkable, the treatment itself is relatively straightforward, consisting of a regimented protocol of periodic fasting-like conditions.

Generally speaking, Type 1 diabetes results from an autoimmune mediated depletion of insulin secreting pancreatic beta islet cells. In contrast, Type 2 results from lower cellular sensitivity to insulin. Type 2 is primarily caused by environmental factors such as poor diet.

Creating oral formulations of intravenous (IV) medication is a daunting challenge. Scientists at SRI Biosciences are using advanced formulation tools and experience to overcome the challenges, with the goal of developing drugs that could easily be distributed to people if needed.

What happens when diagnosis is automated?

HAL-like control of data backups may be science fiction, but some of the basic concepts are not so far removed from reality. The person in charge of strategy for Commvault is intrigued by these ideas.

Tencent, Asia’s second highest valued tech firm, has bought a five percent share in Tesla. According to a filing, the Chinese firm scooped up 8,167,for around $1.7 billion to become one of Tesla’s largest shareholders.

The news itself sent Tesla’s share price up three percent in pre-market trading. The purchase was arranged on March 17, and those now-Tencent-owned shares are worth around $2.2 billion at current market value.

Tencent is a prolific investor. It holds equity in Snap, this year’s hot tech IPO, among others following an early investment. While that interest in messaging makes sense since Tencent’s operates China’s dominant chat app — WeChat — it isn’t immediately clear whether the Tesla investment has strategic undertones. An alliance with Tencent could significantly boost Tesla’s efforts in China, which is already impressive. Chinese sales accounted for 15 percent of Tesla’s $7 billion revenue last year.

Is artificial intelligence stuck in A rut?

The former director of Uber’s AI lab says the field is in danger of losing sight of its long-term goals.
