With One False Tweet, Computer-based Hack Crash Led to Real Panic

May 21, 2015 9:30 am | by Bert Gambini, University at Buffalo | News | Comments

A false tweet from a hacked account owned by the Associated Press in 2013 sent financial markets into a tailspin. The Dow Jones Industrial Average dropped 143.5 points and the Standard & Poor’s 500 Index lost more than $136 billion of its value in the seconds that immediately followed the post. Once the nature of the tweet was discovered, markets corrected themselves, but the Hack Crash event demonstrates the need...

Smart Algorithms Secure Chip Cards against Hackers

May 21, 2015 8:47 am | by University of Twente | News | Comments

Scientists have succeeded in securing chip cards against leaking confidential information. Through the use of smart algorithms, it is now possible to better secure bank cards, public transport chip cards and electronic keys of buildings and cars against hackers. Begül Bilgin developed clever ways to make chip cards more secure against the leaking of confidential information, drafting smart algorithms based on multi-party computation.

Age of Wearable Computing Delivers BioStamp Electronic Skin

May 20, 2015 3:32 pm | by Suzanne Tracy, Editor-in-Chief, Scientific Computing and HPC Source | News | Comments

MC10  is developing a technology that will allow digital circuits to be embedded in bendable, stretchable materials, which allows exploration of entirely new form factors for electronics — including a form of “electronic skin.” MC10 has overcome the rigidity of normal electronic components by printing them in very small pieces and arranging them in wavy patterns. BioStamp, a flexible computing prototype, can be worn constantly.

Obama: Climate Change Deniers Endanger National Security

May 20, 2015 2:26 pm | by Nancy Benac, Associated Press | News | Comments

President Barack Obama said May 20, 2015, the threat posed by climate change is evident all around and that those who deny the "indisputable" science that it is real are putting at risk the security of the United States and the military sworn to defend it. Obama said refusing to act to slow the effects of global warming, including rising seas, amounts to a "dereliction of duty" and undermines the readiness of U.S. forces.

Journey to Space in a Vacuum Chamber

May 20, 2015 9:07 am | by NASA | News | Comments

When you need to test hardware designed to operate in the vast reaches of space, you start in a vacuum chamber. NASA’s Glenn Research Center in Cleveland has many of them, but Vacuum Chamber 5 (VF-5) is special. Supporting the testing of electric propulsion and power systems, VF-5 has the highest pumping speed of any electric propulsion test facility in the world, which is important in maintaining a continuous space-like environment.

Next-gen Computing: Closing in on Speeds Millions of Times Faster than Current Machines

May 19, 2015 4:49 pm | by University of Utah | News | Comments

Engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines. They have developed an ultracompact beamsplitter — the smallest on record — for dividing light waves into two separate channels of information. The device brings them closer to producing silicon photonic chips that compute and shuttle data with light instead of electrons.

Software and Moore’s Drumbeat (Moore’s Law)

May 19, 2015 2:48 pm | by James Reinders, Intel | Blogs | Comments

Moore’s Law recently turned 50 years old, and many have used the milestone to tout its virtues, highlight positive results that stem from it, as well as advance suggestions on what the future dividends will be and boldly project the date for its inevitable demise. Moore’s Law is an observation that has undoubtedly inspired us to innovate to the pace it predicts. It has challenged us to do so. Therefore, I think of it as Moore’s drumbeat.

Cost of LIMS: True Pricing includes more than Purchase, Implementation and Annual Licensing

May 18, 2015 3:02 pm | by Siri H. Segalstad | Articles | Comments

The real benefit of laboratory information management systems (LIMS) is difficult to calculate. Let’s take a look at some key considerations, starting with the question of whether to build the LIMS yourself or buy a commercial LIMS… Advocates for building a new LIMS themselves usually state that their lab is so unique, they cannot use a commercial LIMS. However, very few labs are truly unique ...

Blind Signatures Using Offline Repositories Provide New Level of Security

May 15, 2015 3:35 pm | by World Scientific | News | Comments

In the new era of quantum computers, many daily life applications, such as home banking, are doomed to failure, and new forms of ensuring the confidentiality of our data are being study to overcome this threat. Researchers have taken a step in this direction and propose a quantum blind signature scheme, which ensures that signatures cannot be copied and that the sender must compromise to a single message.

Counterintuitive Approach Yields Big Benefits for High-dimensional, Small-sized Problems

May 15, 2015 3:04 pm | by Agency for Science, Technology and Research (A*STAR) | News | Comments

Extracting meaningful information out of clinical datasets can mean the difference between a successful diagnosis and a protracted illness. However, datasets can vary widely both in terms of the number of ‘features’ measured and number of independent observations taken. Now, researchers have developed an approach for targeted feature selection from datasets with small sample sizes, which tackles the so-called class imbalance problem.

Scientists at Work: Most Days in the Life of an Astronomer aren’t spent at Telescopes

May 11, 2015 10:38 am | by Nicole Estefania Cabrera Salazar, Georgia State University | Articles | Comments

On a telescope at the summit of Mauna Kea in Hawaii, it’s not easy to put in a full night of work. At 14,000 feet, you’re operating at only 60 percent of the oxygen available at sea level, which makes concentrating difficult. Top that off with a shift that begins at 6:30 pm and ends at 6:30 am, and it becomes hard to imagine astronomers working like that year-round. Luckily, most of us don’t have to.
