World-famous physicist and cosmologist Stephen Hawking made a dramatic appearance at the Sydney Opera House via hologram at a sold-out public lecture on April 26, 2015. The world-first “Evening with Stephen Hawking” event, a night celebrating the phenomenal story of Professor Hawking, was the result of a partnership between UNSW, Cisco and the Sydney Opera House. Hawking beamed in via the latest in collaboration technology.
As ubiquitous as the term “big data” has become, the path for drawing real, actionable insights hasn’t always been as clear. And the need is only becoming greater as organizations generate greater and greater amounts of structured and unstructured data. While data-intensive computing is not new to (HPC environments, newer analytic frameworks, including Hadoop, are emerging as viable compasses for navigating the complex amounts of data.
If you find yourself sweating out a day that is monstrously hot, chances are you can blame humanity. A new report links three out of four such days to man's effects on climate. And as climate change worsens around mid-century, that percentage of extremely hot days being caused by man-made greenhouse gases will push past 95 percent.
At first glance, there is not the slightest doubt: to us, the universe looks three-dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle” asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as 3-D may just be the image of 2-D processes on a huge cosmic horizon.
Universal Resource Broker is an enterprise-class workload optimization solution for high performance, containerized and shared data centers. It is designed to enable organizations to achieve massive scalability of shared data center resources and to lay the foundation for the Internet of Things.
IBM is bringing its Security Intelligence technology, IBM QRadar, to the cloud, giving companies the ability to quickly prioritize real threats and free up critical resources to fight cyberattacks. The new services are available through a cloud-based software as a service (SaaS) model, with optional IBM Security Managed Services to provide deeper expertise and flexibility for security professionals.
This 40x photo, entitled "Rising Sun" features a cultured embryonic chicken dorsal root ganglia neuron explant. It received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope.
In order to sing or speak, around one hundred different muscles in our chest, neck, jaw, tongue and lips must work together to produce sound. Researchers investigate how all these mechanisms effortlessly work together — and how they change over time. With a new magnetic resonance imaging (MRI) technique, the vocal neuromuscular movements of singing and speaking can now be captured at 100 frames per second.
In a contest that echoes Deep Blue’s chess victory over Garry Kasparov and Watson beating two Jeopardy! Champions, computer poker software developed at Carnegie Mellon University will challenge four of the world’s best professional poker players in a “Brains Vs. Artificial Intelligence” competition beginning April 24, 2015, at Rivers Casino.
After 60 years of false starts, the integration of artificial intelligence with probability and statistics has led to a marriage of machine learning, control theory and neuroscience that is yielding practical benefits. This shared theoretical foundation, combined with the exponential growth of processing power and the unprecedented increase in the amount of data available to analyze, has made AI systems attractive for businesses to adopt.
Ever since computers have been small enough to be fixtures on desks, their central processing has functioned something like an atomic Etch A Sketch, with electromagnetic fields pushing data bits into place to encode data. Unfortunately, the same drawbacks and perils of the mechanical sketch board have been just as pervasive in computing: making a change often requires starting over, and dropping the device could wipe out the memory.
Part of Italy’s Molise, Apulia and Campania regions are pictured in this radar composite image from Sentinel-1A. The area features two distinct types of terrain: the Apennine Mountains in the lower left and lowlands to the right. Known for its agricultural importance, the lowland area is known as the Tavoliere — a term that recalls the word tavolo meaning ‘table.’
Just as the extraordinary capabilities of 3D printing have begun to infiltrate industry and the family home, researchers have started to develop 3D printed materials that morph into new structures post production, under the influence of external stimuli, such as water or heat — hence the name, 4D printing.
Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park. It's big enough to fill the Grand Canyon 11 times over. The gigantic magma chamber is four times bigger and much deeper than the previously known chamber above it. The upper chamber was responsible for three ancient volcanic eruptions that coated much of North America in ash.
