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.

Hadoop on Lustre: A Storage Blueprint for Deriving Value from Data

April 27, 2015 4:00 pm | by Mike Hoard, Seagate Cloud Systems and Solutions | Blogs | Comments

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.

Study Blames Global Warming for 75 Percent of Very Hot Days

April 27, 2015 11:22 am | by Seth Borenstein, AP Science Writer | News | Comments

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.

Describing the universe requires fewer dimensions than we might think. New calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself.

Is the Universe a Hologram? New Calculations Suggest Holographic Principle Holds in Flat Spacetime

April 27, 2015 11:03 am | by TU Wien | News | Comments

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.

Super-Fast MRI Technique shows what it looks Like to Sing 'If I Only Had a Brain'

April 27, 2015 9:32 am | by Beckman Institute | News | Comments

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.

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.

Spintronic Data Storage: Putting a New Spin on Memory

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.

Huge Magma Chamber Spied under Yellowstone Supervolcano

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.
