U.S. Department of Energy Asks, Is Cloud Computing Fast Enough for Science?
With cloud computing gaining acceptance in the business world, the U.S. Department of Energy wants to know if cloud computing can also meet the needs of the scientific computing. The National Energy Research Scientific Computing Center (NERSC) has launched Magellan, a cloud computing testbed to explore this question, with facilities that will test the effectiveness of cloud computing for scientific projects.
Battery Breakthrough Could Revolutionize Mobile Computing
Researchers at Stanford University have just made a major breakthrough that may impact the technology industry for years to come: they've built a better battery. The project, an attempt to use lithium-sulfur in place of the lithium-ion technology that is used in batteries today, has been in development since 2007. Recently, the scientists' efforts were rewarded when they created a battery that lasts four times as long as its lithium-ion counterparts while also having the benefit of being "significantly safer" than today's batteries which occasionally explode after short-circuiting.
Although still a ways off from commercial viability (and availability), the lithium-sulfur batteries promise advances like 80% more capacity, 10 times the power density and, theoretically, the ability to last four times as long as modern batteries.
Obama, Kids, & All Tomorrow's Web Apps: President Focuses on Tech Education
At the White House today, President Obama talked robots, hung out with the guys from MythBusters, and launched a campaign designed to create smarter, techier American kids."Reaffirming and strengthening America's role as the world's engine of scientific discovery and technological innovation is essential to meeting the challenges of this century," said Obama." That's why I am committed to making the improvement of STEM [science, technology, engineering, and math] education over the next decade a national priority."
Elsevier's Prototype: Is This The Scientific Article of the Future?
Giant science publisher Elsevier announced this week that it is developing what it calls The Article of the Future, a new method of leveraging the web's multi-media capabilities for presenting academic articles online. The company says it seeks to offer readers "individualized entry points and routes through the content, while using the latest advances in visualization techniques." It's got AJAX and it's got real-time web search.
Some parts of the available prototypes are interesting but opinion in the scientific community seems split. Is this ground-breaking stuff or yesterday's news repackaged by another industry threatened by the web? That depends on who you ask.
A Productive Application of Semantic Search
Noesis is a new semantic web search engine that helps scientists studying the environment access and retrieve the research data they need. Developed at the University of Alabama in Huntsville, the new engine has the potential to enable scientists and researchers everywhere to perform more productive and focused searches thanks to the semantic technology Noesis uses.
Open Knowledge Sharing for the Dynamic Web
The EU-funded OpenKnowledge program is a smart toolkit designed to unlock the hidden resources of the web that can't be accessed by web sites and browsers alone. With a small, downloadable piece of Java code, users can coordinate and share information with each other more directly than through traditional means. To highlight the potential of the OpenKnowledge system, researchers have put it to work in three different areas: healthcare services, emergency management, and proteomics research.
Smiling in Your Social Network Photos? You Probably Have More Friends
Researchers Nicholas Christakis and James Folwer recently published a paper in the British Medical Journal where they examined how a person's happiness is related to the happiness of their friends in their offline social networks. To follow up that study, they examined those same happiness clusters in online networks like MySpace and Facebook. Their conclusion? Happier people tend to have more friends and are more central to the network when compared with their more sullen friends.
"Yes We Can" Director Releases Video About Science Commons
Film director Jesse Dylan, the co-creator of the Emmy award winning Barack Obama support video Yes We Can has released a new work, this time explaining the Creative Commons Foundation's science initiative, Science Commons.
Dylan, who coincidentally is the eldest son of folk legend Bob Dylan, uses his familiar style to aggregate a quick selection of scientists explaining why a web-based revision of copyright policy is so important for the advancement of scientists. "Scientists are the ultimate remixers," one interviewee says, and we agree that Creative Commons in science is a very exciting idea.
Education 2.0: Never Memorize Again?
Memorization is a waste of time when Google is only a a few clicks away. That's what Don Tapscott, author of the bestselling books Wikinomics and Growing Up Digital, believes. Tapscott, considered by many to be a leading commentator on our Internet age, believes the age of learning through the memorization of facts and figures is coming to an end. Instead, students should be taught to think creatively and better understand the knowledge that's available online.
CERN Officially Unveils Its Grid: 100,000 Processors, 15 Petabytes a Year
CERN today officially unveiled the massive computer network that will crunch the enormous amount of data coming from CERN's Large Hadron Collider (LHC). CERN expects that the LHC will produce around 15 petabytes of data every year. While the LHC was in its planning stages, CERN's IT department decided that the only realistic way to handle this amount of data would be by relying on the then still novel idea of grid computing. CERN's grid consists of 100,000 processors at 140 scientific institutions in 33 countries.
