A Pioneer in Data-intensive HPC, SDSC Celebrates 30 Years Supporting the Long Tail of Science

October 27, 2015 10:27 am | by Doug Black | Comments

Celebrating its 30th anniversary, the San Diego Supercomputer Center likes to refer to itself as an HPC resource “for the 99 percent.” Its mission: support thousands of scientific end users, most of them running jobs that typically occupy only a small amount of the processing power contained in the Center’s world-class systems. Scientists come to SDSC for a cyberinfrastructure designed to support high numbers of end-users...

Chemistry Nobel DNA Research Lays Foundation for New Ways to Fight Cancer

October 9, 2015 8:16 am | by Rachel Litman Flynn, Boston University | Comments

Our cells are up against a daily onslaught of damage to DNA that encodes our genes. It takes constant effort to keep up with DNA disrepair — and if our cells didn’t bother to try to fix it, we might not survive. DNA damage repair pathways are an essential safeguard for the human genome. The 2015 Nobel Laureates in chemistry received the prize for their pioneering work figuring out the molecular machinery cells use to repair that damage.

How Neutrinos, which Barely Exist, Just Ran Off with another Nobel Prize

October 7, 2015 9:29 am | by John Beacom, Ohio State University | Comments

Neutrinos take patience. They’re worth it, and the announcement of the 2015 Nobel Prize in Physics recognizes that, following related prizes in 1988 and 2002. Ironically, these near-undetectable particles can reveal things that cannot be seen any other way. Why should you care, beyond sharing our curiosity about revealing some of the weirdest things in the universe?

At the height of the Cultural Revolution, Project 523 – a covert operation launched by the Chinese government and headed by young Chinese medical researcher Tu Youyou – discovered what has been the most powerful and effective antimalarial drug therapy to date. Derived from the sweet wormwood, artemisinin was only one of several hundred substances researchers culled from Chinese drugs and folk remedies and systematically tested.

How Supercomputers aid Oil and Gas Seismic Research

October 6, 2015 3:59 pm | by Linda Barney | Comments

In today’s oil and gas industry, technology and supercomputers are used to help lower costs and decrease time required to discover deposits of petroleum buried under water and rock. Energy exploration, production and reservoir monitoring is the most significant big data and compute-intensive application in the private sector. To help reduce costs and impact on the environment, companies are turning to supercomputers to aid in exploration.

The Martian: A Space Epic that Explores Ordinary Human Decency

October 5, 2015 9:17 am | by Stephen Benedict Dyson, University of Connecticut | Comments

On the red planet, amid arid desert and rolling mountain ranges, six sleekly space-suited astronauts grope their way back to their launch vehicle, fleeing a sudden and vicious wind storm. Pelted and blinded by sand and metal, one of them is struck by debris and flung off into the darkness. The others, unable to stay any longer, leave him for dead, blasting off for Earth. Later, the abandoned astronaut is snapped back to consciousness...

Science DMZ Infrastructure Architecture Accelerates Data Flows

October 1, 2015 2:56 pm | by Berkeley Lab Computing Sciences | Comments

From individual universities around the country to a consortium of research institutions stretching the length of the west coast, networking teams are deploying an infrastructure architecture known as Science DMZ to help researchers make productive use of ever-increasing data flows. It traces its name to an element of network security architecture, where a demilitarized zone is a portion of a network dedicated to external-facing service.

How Close are We to Actually Becoming Martians?

October 1, 2015 9:11 am | by Sidney Perkowitz, Emory University | Comments

Like any long-distance relationship, our love affair with Mars has had its ups and downs. A century ago, the American astronomer Percival Lowell mistakenly interpreted Martian surface features as canals that intelligent beings had built to distribute water across a dry world. This was just one example in a long history of imagining life on Mars. The latest entry is the sci-fi flick The Martian.

Mass extinctions are more complicated than ‘strength in numbers. Early on in the process, numbers are far from carrying capacity, and growth is exponential. Later on, progressively harder brakes are put on, and the rate of growth slows down, so that diver

Which Species will survive the Earth’s Sixth Mass Extinction?

September 23, 2015 8:52 am | by Matthew Wills, University of Bath | Comments

Scientists recently suggested that the Earth’s sixth mass extinction has begun. As terrifying as that sounds, surely humans are too smart and too important to get wiped out? Palaeontologists have long tried to shed light on this question by looking for general rules that might predict the survival of a species. While this is not exactly a straightforward exercise, research so far indicates that the odds are not in our favor.

Patterns are Math We Love to Look At

September 22, 2015 9:27 am | by Frank A Farris, Santa Clara University | Comments

Why do humans love to look at patterns? I can only guess, but I’ve written a whole book about new mathematical ways to make them. In Creating Symmetry, The Artful Mathematics of Wallpaper Patterns, I include a comprehensive set of recipes for turning photographs into patterns. The official definition of “pattern” is cumbersome; but you can think of a pattern as an image that repeats in some way...

Stunning, Crystal-clear Images of Pluto – But What do They Mean?

September 21, 2015 10:25 am | by David Rothery, The Open University | Comments

The more we find out about Pluto, the more perplexing it seems. For several weeks after its July 14 fly-by, NASA’s probe New Horizons was too busy doing science to transmit data to Earth. During that time we had to content ourselves with the few “taster” images that were beamed back immediately after it passed Pluto. However the probe has now begun the year-long process of transmitting its vast haul of fly-by data.
