Using Wall Street secrets to reduce the cost of cloud infrastructure
Researchers have developed a 'risk-aware' model that improves the performance of cloud-computing infrastructure used across the globe.
Wearable sensors detect what's in your sweat
A team of scientists is developing wearable skin sensors that can detect what's in your sweat. In a new article, the team describes a sensor design that can be rapidly manufactured using a ''roll-to-roll'' processing technique that essentially prints the sensors onto a sheet of plastic like words on a newspaper. The sensors can provide real-time measurements of sweat rate, and electrolytes and metabolites in sweat.
Wireless sensors that stick to the skin to track our health
Engineers have developed experimental stickers that pick up physiological signals emanating from the skin, then wirelessly beam these health readings to a receiver clipped onto clothing. It's all part of a system called BodyNet.
Newfound superconductor material could be the 'silicon of quantum computers'
Newly discovered properties in the compound uranium ditelluride show that it could prove highly resistant to one of the nemeses of quantum computer development -- the difficulty with making such a computer's memory storage switches, called qubits, function long enough to finish a computation before losing the delicate physical relationship that allows them to operate as a group. This relationship, called quantum coherence, is hard to maintain because of disturbances from the surrounding world.
Better food and faster analysis of blood tests
Researchers have figured out how to use deep learning to speed up the analysis of gas chromatographic data. Because this type of analysis is used in many parts of society, the new method will have a major impact on quality, efficiency and cost when examining various data -- from blood tests, to the fermentation of cheese.
Researchers use blockchain to drive electric-vehicle infrastructure
Researchers have integrated the use of blockchain into energy systems, a development that could result in expanded charging infrastructure for electric vehicles.
Attackers could be listening to what you type
You likely know to avoid suspicious emails to keep hackers from gleaning personal information from your computer. But a new study suggests that it's possible to access your information in a much subtler way: by using a nearby smart phone to intercept the sound of your typing.
App allows inspectors to find gas pump skimmers faster
Computer scientists have developed an app that allows state and federal inspectors to detect devices that steal consumer credit and debit card data at gas pumps. The devices, known as skimmers, use Bluetooth to transmit the data they steal.
AI tool characterizes a song's genre and provides insights regarding perception music
An artificial intelligence tool can characterize a song's genre and provides increased understanding how we perceive and process music. Applications include how music content is marketed, consumed and tagged; neuropsychology and the mechanisms of human thought; and affective computing systems that impact human emotions.
Virtual 'universe machine' sheds light on galaxy evolution
By creating millions of virtual universes and comparing them to observations of actual galaxies, researchers have made discoveries that present a powerful new approach for studying galaxy formation.
Turbulence meets a shock
Interaction of shocks and turbulence investigated with a focus on high intensity turbulence levels. A new theoretical framework was developed and tested to understand turbulent jumps of mean thermodynamic quantities, shock structure and amplification factors. TACC's XSEDE-allocated Stampede2 ran simulations of shock turbulence interactions at unprecedented levels of realism. Research could help develop supersonic and hypersonic aircraft, more efficient engine ignition, as well as probe the mysteries of supernova explosions, star formation, and more.
Artificial intelligence could yield more accurate breast cancer diagnoses
Researchers have developed an artificial intelligence system that could help pathologists read biopsies more accurately and to better detect and diagnose breast cancer.
Method to automatically estimate rooftop solar potential
The progress of rooftop solar installations is often slowed by a shortage of trained professionals who must use expensive tools to conduct labor-intensive structure assessments one by one, say scientists. Now researchers are proposing a new, data-driven approach that uses machine learning techniques and widely available satellite images to identify roofs that have the most potential to produce cost-effective solar power.
Seeing how computers 'think' helps humans stump machines and reveals AI weaknesses
Researchers have figured out how to reliably create questions that challenge computers and reflect the complexity of human language through a human-computer collaboration, developing a dataset of more than 1,200 questions that, while easy for people to answer, stump the best computer answering systems today. The system that learns to master these questions will have a better understanding of language than any system currently in existence.
Google maps for tissues
Modern light microscopic techniques provide extremely detailed insights into organs, but the terabytes of data they produce are usually nearly impossible to process. New software is helping researchers make sense of these reams of data.
