New Kind of Computer Chip uses Flexible, Biodegradable Cellulose Nanofibril Substrate

May 27, 2015 10:25 am | by John Steeno, University of Wisconsin-Madison | News | Comments

Portable electronics — typically made of non-renewable, non-biodegradable, potentially toxic materials — are discarded at an alarming rate in consumers' pursuit of the next best electronic gadget. In an effort to alleviate the environmental burden of electronic devices, researchers developed a surprising solution: a semiconductor chip made almost entirely of wood. They addressed two key barriers: surface smoothness and thermal expansion.

Deriving Real Time Value from Big Data

May 22, 2015 9:51 am | by Pat McGarry, Ryft Systems | Blogs | Comments

Everyone has heard the old adage that time is money. In today’s society, business moves at the speed of making a phone call, looking something up online via your cell phone, or posting a tweet. So, when time is money (and can be a lot of money), why are businesses okay with waiting weeks or even months to get valuable information from their data?

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.

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.

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 ...

Two experiments at the Large Hadron Collider at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have combined their results and observed a previously unseen subatomic process. A joint analysis by the CMS and LHCb collaborations has established a new and extremely rare decay of the Bs particle (a heavy composite particle consisting of a bottom antiquark and a strange quark) into two muons.

Researchers show how to build a digital blind signature scheme under the assumption that they have an offline repository and are using quantum information.

Blind Signatures Using Offline Repositories Provide New Level of Security

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.
