More news on Google’s AI kill switch — I am glad that it exist.

Developers are pondering on methods to prevent catastrophe in case an Artificial Intelligence, or AI, got ahead of its designated programming.

Theoretical scientist Stephen Hawking, entrepreneur for Tesla Motors Elon Musk, and Microsoft co-founder Bill Gates mentioned that AIs have a high learning curve regarding self-awareness, and anytime soon, AIs might surpass human knowledge and become sentient. In a 2014 interview, theoretical physicist Stephen Hawking stated that the evolution of humans is slower compared to the rapid improvement of robots.

So, all of this nextgen technology is wonderful; I truly see the vision and how to make it happen over time. However, what about the native people of the countries where this innovation and advancement is occurring? Are they getting the opportunity to be a part of the innovation story? Or, are they being left behind?

At Microsoft, we established many programs and outreach programs to engage many of the Native Americans across the US; I would like to encourage others to think about how can more be done to include the indigenous people of your countries to be part of the innovation/ evolution story. It truly is rewarding to so many.

The first Native Youth My Brother’s Keeper Hackathon saw students produce several games, apps.

Over the course of one weekend at the end of April in Albuquerque, NM, a few days of frantic organizing gave birth to the city’s first-ever Native Youth My Brother’s Keeper Hackathon, or #NativeMBK.

“It was a shoestring budget,” said Seth Saavedra, director of talent and advancement at Albuquerque’s Native American Community Academy. “We thought, let’s just make this happen. And it went serendipitously well.”

The human genome contains more than 20,000 protein-coding genes, which carry the instructions for proteins essential to the structure and function of our cells, tissues and organs. Some of these genes are very similar to each other because, as the genomes of humans and other mammals evolve, glitches in DNA replication sometimes result in extra copies of a gene being made. Those duplicates can be passed along to subsequent generations and, on very rare occasions, usually at a much later point in time, acquire additional modifications that may enable them to serve new biological functions. By starting with a protein shape that has already been fine-tuned for one function, evolution can produce a new function more rapidly than starting from scratch.

Pretty cool! But it leads to a question that’s long perplexed evolutionary biologists: Why don’t duplicate genes vanish from the gene pool almost as soon as they appear? After all, instantly doubling the amount of protein produced in an organism is usually a recipe for disaster—just think what might happen to a human baby born with twice as much insulin or clotting factor as normal. At the very least, duplicate genes should be unnecessary and therefore vulnerable to being degraded into functionless pseudogenes as new mutations arise over time.

An NIH-supported team offers a possible answer to this question in a study published in the journal Science. Based on their analysis of duplicate gene pairs in the human and mouse genomes, the researchers suggest that extra genes persist in the genome because of rapid changes in gene activity. Instead of the original gene producing 100 percent of a protein in the body, the gene duo quickly divvies up the job [1]. For instance, the original gene might produce roughly 50 percent and its duplicate the other 50 percent. Most importantly, organisms find the right balance and the duplicate genes can easily survive to be passed along to their offspring, providing fodder for continued evolution.

Researchers recently made an important discovery in protein science that will advance our understanding of the inner workings of cells. In an article published in Scientific Reports, the team said they found a critical evolutionary link between a protein’s structure and its function.

Like tiny molecular machines, proteins handle a variety of functions from transporting chemicals to breaking food down into nutrients. The vast range of protein function is possible because of their unique gene-encoded sequence of amino acids, which affects the three-dimensional shape that folded protein chains adopt.

To better understand them, researchers have sequenced and resolved a huge number of protein structures. Currently, the Protein Data Bank includes 110,000+ structures—far more than the number with known functions. Powerful bioinformatics tools assist in making correlations between the shape and purpose of a protein, but what’s been missing is a direct structure-function link, tantamount to a Rosetta stone-like key.

Luv this article (science meets philosophical theory on the evolution of science); reminds me of an article that one of my Quantum friends shared yesterday on Linkedin Pulse.

Science is the biggest enterprise that man ever created. Of all the living things on this planet, man is the only one that seems to have started thinking about how this world works. To understand that he started this new venture, called Science, which was originally meant just to understand how this world works. Some exceptionally brilliant minds did accidentally stumble upon some understanding of the world’s laws like gravity, buoyancy, and others in the west while Indian sages had realised this much earlier.

Next step was to find out how the world works by doing some experiments. That was the stage when the Churches started obstructing “Science” as this kind of scientific enquiry, the Church felt, might interfere with religious beliefs. That is where the first conflict between religion and science started. The fall out was that scientists subconsciously developed an aversion to the God concept in religion and thus God was kept out of the scientific realm. Let us, therefore, think from now on. Science, then, was more of a hobby for the well to do. The leading lights of that generation were Isaac Newton and Albert Einstein. There were a host of others but less illustrious than these two. Newton’s Laws of deterministic predictability and Einstein’s laws of relativity together founded a world view of “space-time” constraints where everything else out with this space time module was rejected.

US biochemical engineer Frances Arnold on Tuesday won a million-euro technology prize in Finland for her work on “directed evolution”, a method of rewriting DNA to improve medicines and develop green fuels.

“Frances Arnold receives the 2016 Millennium Technology Prize in recognition of her discoveries that launched the field of ‘directed evolution’, which mimics natural evolution to create new and better proteins in the laboratory,” the Technology Academy Finland, which awards the prize at two-year intervals, said in a statement.

Arnold, 59, who is a professor of chemical engineering at California Institute of Technology, said her work made it possible to “solve human problems”, such as replacing toxic chemicals like fossil fuels.

Biologists have identified the one gene that caused the evolution of single-celled organisms into multicellularity, debunking previous theories that several genes were at play. The gene retinoblastoma is also the same gene that is found to be defective in cancer patients, and suppresses tumors.
