On May 18, 1980, Mount St. Helens gave way to a cataclysmic flank collapse, avalanche and explosion that killed 57 people and displaced many others. The event dramatically reshaped the volcano and surrounding land in southwest Washington. Now, 35 years later, satellites in orbit and scientists on the ground still monitor the mountain and track its recovery. This image shows a three-dimensional view of the mountain.
Random-access memory is where computers like to store the data they’re working on. A processor can retrieve data from RAM tens of thousands of times more rapidly than it can from the computer’s disk drive. But in the age of big data, data sets are often much too large to fit in a single computer’s RAM. Flash memory could provide an alternative for big-data applications. It’s about 1/10 as expensive and consumes about 1/10 as much power
The iPlant Collaborative, headquartered at the University of Arizona, is a National Science Foundation-funded cyberinfrastructure project providing computational support to life science researchers in the form of secure data storage, services for data analysis, and the underlying infrastructure to share datasets among collaborators anywhere in the world with an Internet connection.
Here they are — the top most visited stories from the past week. A spyware peddler suffers a major hack; experimental artificial heart is a success; 8-minute video of Rover Opportunity’s Epic Mars Marathon; astounding new mosaic image of our Sun’s surface, and a series of intriguing spots along Pluto’s’ equator are all among the top hits.
A new model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Predictions from the model suggest that solar activity will fall by 60 percent during the 2030s to conditions last seen during the ‘mini ice age’ that began in 1645.
NASA has released a new video in which a compilation of images taken by the Mars Exploration Rover Opportunity’s hazard-avoidance cameras between January 2004 and April 2015 reveals an awe-inspiring rover's-eye-view of the 26.2-mile marathon from its landing location, as a corresponding map of the rover's path appears alongside. Audio is derived from vibration measurements from the rover’s accelerometer.
NASA pilot Jim Less and photographer Jim Ross pull their F-15D #897 aircraft away from a KC-135 refueling tanker. NASA is supporting the Edwards Air Force Base F-15 program with safety and photo chase expertise. NASA research support aircraft are commonly called chase planes and fill the role of escort aircraft during research missions.
Teradata Appliance for Hadoop 5 is configurable, ready-to-run and offers a choice of the latest version of Hadoop from Hortonworks (HDP 2.3), and for the first time, Cloudera (Cloudera Enterprise 5.4). The appliance facilitates integration with the Teradata Unified Data Architecture (UDA), a framework for organizations to address all types of data and multiple Teradata systems.
IBM Research announced that, working with SUNY Polytechnic Institute’s Colleges of Nanoscale Science and Engineering, it has produced the semiconductor industry’s first 7nm node test chips with functional transistors. The accomplishment is driven by a $3 billion investment, where researchers are pushing the limits of chip technology to meet the demands of cloud computing, big data systems, cognitive computing and mobile products.
This Sunday, Frankfurt will become a hot spot in the HPC community, as 2,600 enthusiasts from 53 countries and 153 exhibitors make their way to the city to kick off the ISC High Performance conference and exhibition. The international conference will take place from July 12 to 16, 2015, and ISC reports that current registration points toward a record number of attendees. In particular, international attendance is surging...
ACD/Labs and IDBS announced a new partnership to deliver an enhanced analytical sciences environment for IDBS Electronic Laboratory Notebook (ELN) users in the chemistry and biology space. The collaborative effort has begun with an integration of ACD/Labs’ Spectrus and IDBS’ E‑WorkBook 10 web technologies to bring live analytical data into the scientists’ ELN interfaces.
Each cell in the body contains a whole genome, yet the data packed into a few DNA molecules could fill a hard drive. As more people have their DNA sequenced, that data will require massive computational and storage capabilities beyond anything previously anticipated. Computational biologists and computer scientists compared data needs of genomics with three of the biggest players in big data: astronomy, Twitter and YouTube.
From agricultural disruptions to rising sea levels, changing climate conditions have far-reaching impacts that require local and regional attention. With dynamical downscaling, researchers can use outputs from coarse-resolution global models to drive higher-resolution regional climate models. The enhanced resolution allows models to better account for topographic details, while also improving simulation of surface variables.
The ActiveStor 18 hybrid scale-out NAS appliance increases scalability to more than 20 petabytes (PB) and 200 gigabytes per second (GB/s) by adopting 8 terabyte (TB) drive technology. It also offers increased CPU power and twice the storage cache capacity to further accelerate mixed workload performance.
Flaring, active regions of our sun are highlighted in this new image combining observations from several telescopes. High-energy X-rays from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan's Hinode spacecraft are green; and extreme ultraviolet light from NASA's Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time.
