IBM is currently attempting to merge artificial intelligence and the blockchain into a single, powerful prototype. With blockchain tech's promise of near-frictionless value exchange and artificial intelligence's ability to accelerate the analysis of massive amounts of data, the joining of the two could mark the beginning of an entirely new paradigm. Over the past three months, IBM's chief architect in charge of Internet of Things security Tim Hahn has focused specifically on introducing the blockchain to his company's artificially intelligent computer named Watson. "What we're doing with blockchain and devices is enabling the information those devices supply to effect the blockchain…You begin to approach the kind of things we see in movies." Potential applications include using distributed ledgers to let devices perform tasks like running self-diagnoses at set times and more advanced services that may someday let regulators virtually go back in time to the point where a device failed and "to identify exactly what went wrong," Hahn said.

As Nvidia (NVDA) CEO Jen-Hsun Huang stood gazing at the Martian surface -- a virtual reality simulation, of course -- he talked about a future for the company that investors should look forward to. At the company's annual GPU Technology Conference, which started here Tuesday, Huang in the opening keynote address told attendees that Nvidia's focus will be even more centered around its core GPU (graphics processing unit) technology. GPUs provide graphics on computers, in video games and in various other applications. Nvidia competes mostly with Advanced Micro Devices (AMD) in this field, but No. 1 chipmaker Intel (INTC) is among other rivals. Huang said the company's key markets will be virtual reality, autonomous cars and artificial intelligence, including chips for drones and deep learning.

In the 1950s, artificial intelligence (AI) became a hot topic of scientific conversation in science fiction novels. The prospect of attacks by intelligent machines became a trend that led the imagination down dark paths of technological domination. AI is no longer science fiction and is on a path of destruction, but not one that could have been predicted 60 years ago. It is playing no small role in the prevention of cybercrime, and leading the fight back in protecting data. Machine learning is providing teams with the capability to thwart APTs (advanced persistent threats) through zero day attacks and with the analytic prowess they need to identify both internal and external threats.

Your electric bills could soar if you kept Nvidia's monster DGX-1 computer running continuously for one month. The DGX-1 supercomputer can deliver the computing power of 250 two-socket servers in a desktop box, claimed Nvidia, which introduced the system Tuesday at its GPU Technology Conference in San Jose, California. The computer can deliver about 170 teraflops of performance, and multiple boxes on a rack could deliver 2 petaflops of performance. The fastest computer in the world delivers a peak performance of about 10 petaflops. Nvidia says DGX-1 is about 56 times faster than a server with two Intel Xeon-E5 2697 v3 chips, which can deliver about 3 teraflops of performance.

Bergan Flannigan, of Plattsburgh, N.Y., says she used to "get a lot of stares" when she wore her prosthetic leg with the metal pipe exposed. "I feel like people don't look as much" with the cover, she says, "which I like." Bergan Flannigan, of Plattsburgh, N.Y., says she used to "get a lot of stares" when she wore her prosthetic leg with the metal pipe exposed. "I feel like people don't look as much" with the cover, she says, "which I like." Prosthetic limbs for people who have lost an arm or a leg have come a long way in the past decade.

Its Computer Science program was ranked among the top 25 in the world in 2015 by QS. The Cheriton School is part of Waterloo's highly regarded and unique Faculty of Mathematics, which also placed in the top 20 in the 2015 QS rankings With those credentials, it is little wonder that the Faculty has more than 7,500 graduate and undergraduate students. The unit's unique blend of computer scientists, mathematicians and statisticians comprise 250 full-time professors. Its researchers lead the scientific community with the depth of their work and the wide spectrum of computer science, mathematics and statistics topics covered. They span the range from theoretical foundations to the immediately practical in all areas.

As a pioneer in human-computer dialogue, multimodal interaction, and artificial intelligence, Phil has the charter to aggressively push VoiceBox's development of Artificial Intelligence (AI). He recently shared how the company's R&D investments and the formation of the Scientific Advisory Board which he oversees, will lead to groundbreaking AI solutions for Automakers. What recent milestones in AI have leading scientists buzzing? There have been numerous AI milestones over the past decade, including: winning the World Chess, Go, and Jeopardy championships, recognizing items in images, recognizing spoken language, and the translating of languages. Many of these milestones were supported by machine learning technologies, most recently Deep Learning Neural Networks (DNN). The basic ideas of neural networks have been worked on continuously for more than 50 years, starting with Rosenblatt's "perceptron".

Our universe certainly seems real, but in recent years, a growing number of scientists have begun to wonder if it's all just a sophisticated simulation. Are we and everything around us nothing more than points of data in some sort of cosmic hologram? A group of celebrated scientists, including Neil deGrasse Tyson, will sit down on Tuesday for a serious discussion of what may sound more like a sci-fi movie plot than reality. The event at New York City's American Museum of Natural History starts at 7 p.m. Eastern time. You can watch it live in the video above.

I believe Richard Feynman was one of our greatest scientific minds. He had a very particular way of looking at the world thanks to his father, and it was to look at the world around him as if he were a Martian. Like a fish born into water, it's hard to actually see water as being water, because it's all a fish ever knows. And so as humans, it's a good idea to try and step outside of our usual frame of mind, to see what it is we as humans think and do, from the perspective of a mind totally alien to our everyday environment. With that in mind, here's what humans are doing right now, from the perspective of someone from far, far away... What an interesting place and an interesting time it is for a visit.
