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.
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.
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.
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.
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.
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 ...
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.
This 5x photo of a common wasp (Vespula vulgaris) stinger received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. The photograph was taken using reflected light and focus stacking.
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.
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.
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.
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.
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.
In case you missed it, here's another chance to catch this week's biggest hits. Writing like a genius; the largest individual structure ever identified by humanity; imaging fascinating, wild and unpredictable thunder; a car prototype that folds, shrinks and drives sideways; a high-efficiency laser system to remove space debris from orbit; and more are among the latest top stories.
Tecplot 360 EX 2015 Release 2 is 10 times faster than the legacy (2013) version of Tecplot 360 at computational analysis and graphics rendering. Features include customizable color maps that allow users to understand variations in their data through the use of graphical point and click color options.
