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.

Investigators have applied NetGestalt to data from The Cancer Genome Atlas (TCGA) colorectal cancer cohort, the first tumor dataset with complete molecular measurements at DNA, RNA and protein levels.

User-friendly Data Query, Visualization Tools Enable Omics Data Integration

May 19, 2015 4:21 pm | by Leigh MacMillan, Vanderbilt University | News | Comments

Advances in technology have generated vast amounts of “omics” data: genomic, epigenomic, transcriptomic, proteomic and metabolomic changes for all types of specimens. Bridging the gap between data generation and investigators’ ability to retrieve and interpret data is essential to realize the biological and clinical value of this wealth of information.

Star Formation and Magnetic Turbulence in the Orion Molecular Cloud

May 19, 2015 3:17 pm | by ESA | News | Comments

With blue hues suggestive of marine paradises and a texture evoking the tranquil flow of sea waves, this image might make us daydream of sandy beaches and exotic holiday destinations. Instead, the subject of the scene is intense and powerful, because it depicts the formation of stars in the turbulent billows of gas and dust of the Orion Molecular Cloud.

Scientists are now closer to imitating key electronic aspects of the human brain — a vital step towards creating a bionic brain.

Researchers take Vital Step toward Creating Bionic Brain

May 19, 2015 3:08 pm | by RMIT University | News | Comments

Researchers have mimicked the way the human brain processes information with the development of an electronic long-term memory cell, which mirrors the brain’s ability to simultaneously process and store multiple strands of information. The development brings them closer to imitating key electronic aspects of the human brain — a vital step toward creating a bionic brain and unlocking treatments for Alzheimer’s and Parkinson’s diseases.

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 ...

In this photo, Mount St. Helens spews smoke, soot and ash into the sky in Washington state following a major eruption on May 18, 1980. May 18, 2015 is the 35th anniversary of the eruption that killed more than 50 people and blasted more than 1,300 feet of

A Look Back 35 Years after Mount St. Helens' Deadly Eruption

May 18, 2015 12:15 pm | by Phuong Le, Associated Press | News | Comments

Thirty-five years ago, Mount St. Helens in southwest Washington state erupted, killing 57 people, blasting more than 1,300 feet off the top and raining volcanic ash for miles around. Today, the volcano has become a world-class outdoor laboratory for the study of volcanoes, ecosystems and forestry, and scientists are constantly recording activity in and around the mountain.

Two Large Hadron Collider Experiments First to Observe Rare Subatomic Process

May 18, 2015 11:22 am | by Fermi National Accelerator Laboratory | News | Comments

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 Unravel Secrets of Colossal, Invisible Waves in Earth’s Oceans

May 18, 2015 11:10 am | by David L. Chandler, MIT | News | Comments

Detailed new field studies, laboratory experiments and simulations of the largest known “internal waves” in the Earth’s oceans — phenomena that play a key role in mixing ocean waters, greatly affecting ocean temperatures — provide a comprehensive new view of how these colossal, invisible waves are born, spread and die off. The paper is co-authored by 42 researchers from 25 institutions in five countries.

What Colors are the Dress? Three Perspectives on Why the Image is seen Differently

May 15, 2015 3:57 pm | by Cell Press | News | Comments

When you look at this photograph, what colors are the dress? Some see blue and black stripes, others see white and gold stripes. This striking variation took the Internet by storm in February; now Current Biology is publishing three short papers on why the image is seen differently by different observers, and what this tells us about the complicated workings of color perception.

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

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.
