The Pacific Northwest is dotted by small, low-lying, coastal cities where populations tend to cluster. These communities can be isolated and are susceptible to devastation from major storms that bring substantial wind, waves and storm surge. With climate change, it is anticipated that storms will only become more frequent and intense, signifying a need to understand how the areas will be affected.
Analyzing people’s keystrokes as they type on a computer keyboard can reveal a great deal of information about the state of their motor function, according to a new study. In the study, the researchers found that their algorithm for analyzing keystrokes could distinguish between typing done in the middle of the night, when sleep deprivation impairs motor skills, and typing performed when fully rested.
If you’re feeling pressured to be more efficient, you’re not alone. Research labs are facing an ever-growing number of chemical safety regulations and reports. This short video shows how to ensure compliance.
The name sounds like something Marvin the Martian might have built, but the “nanomechanical plasmonic phase modulator” is not a doomsday device. Developed by a team of government and university researchers, including physicists from NIST, the innovation harnesses tiny electron waves called plasmons. It’s a step towards enabling computers to process information hundreds of times faster than today’s machines.
The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories. These results pave the way to developing ultra-high-speed quantum computers and strengthening the security of communication.
Many studies show that video gamers perform better than non-gamers on certain visual tasks, like managing distractors and identifying targets, but a small new Brown Univ. study provides gamers with some cognitive bonus points. The study results suggest that gaming not only improves their visual skill but also may improve their learning ability for those skills.
Oil-based liquid crystals are ubiquitous; an understanding of their properties is behind the displays in most electronics. Water-based liquid crystals are less well understood, though their biocompatibility makes them a candidate for a variety of applications. New research has advanced the field's understanding of these materials, demonstrating never-before-seen configurations by confining a water-based liquid crystal in a cylinder.
Have you ever wondered if your dad's fight with prostate cancer means you could face the same reality? Perhaps your family has several members who have struggled with obesity and you wonder if it's something you inherited or if it's caused by the environment. Maybe you have always wanted to learn where your ancestors came from beyond the basic paper trail. Good news: Researchers have an app for that.
Scientists from ETH Zurich have developed a thermometer that is at least 100 times more sensitive than previous temperature sensors. It consists of a bio-synthetic hybrid material of tobacco cells and nanotubes. Humans have been inspired by nature since the beginning of time. We mimic nature to develop new technologies, with examples ranging from machinery to pharmaceuticals to new materials.
The decades worth of data that has been collected about the billions of neurons in the brain is astounding. To help scientists make sense of this “brain big data,” researchers at Carnegie Mellon Univ. have used data mining to create www.neuroelectro.org, a publicly available Website that acts like Wikipedia, indexing physiological information about neurons.
Speaking in public is the top fear for many people. Now, researchers from the Human-Computer Interaction Group at the Univ. of Rochester have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, while being minimally distracting.
A vibrational spectroscopic imaging technology that can take images of living cells could represent an advanced medical diagnostic tool for the early detection of cancer and other diseases. High-speed spectroscopic imaging makes it possible to observe the quickly changing metabolic processes inside living cells and to image large areas of tissue, making it possible to scan an entire organ.
Geometrically, fractals have forms, or features, that repeat at different sizes over ranges of scales. These features can repeat exactly, such as the triangles that repeat with scale on a Koch snowflake or Minkowski sausage. Or, these features might repeat statistically, as on ground or abraded surfaces, where these repeating features create self-similar patterns of scratches or over a range of scales.
Researchers studying cancer and other invasive diseases rely on high-resolution imaging to see tumors and other activity deep within the body's tissues. Using a new high-speed, high-resolution imaging method, a team at Washington Univ. in St. Louis were able to see blood flow, blood oxygenation, oxygen metabolism and other functions inside a living mouse brain at faster rates than ever before.
From smartphones and tablets to computer monitors and interactive TV screens, electronic displays are everywhere. As the demand for instant, constant communication grows, so too does the urgency for more convenient portable devices, especially devices, like computer displays, that can be easily rolled up and put away, rather than requiring a flat surface for storage and transportation.
Univ. of Notre Dame applied mathematician Mark Alber and environmental biotechnologist Robert Nerenberg have developed a new computational model that effectively simulates the mechanical behavior of biofilms. Their model may lead to new strategies for studying a range of issues from blood clots to waste treatment systems.
Using high-performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion people on it by 2050, researchers report in Cell.
Scientists working at NIST and the NIH have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering.
Big data: It's a term we read and hear about often, but is hard to grasp. Computer scientists at Washington Univ. in St. Louis tackled some big data about an important protein and discovered its connection in human history as well as clues about its role in complex neurological diseases.
Studies confirm that IT investments in companies improve productivity and efficiency. Univ. of Michigan professor M.S. Krishnan wondered if the same was true for government. After all, IT spending could either lead to efficiency or create bureaucratic bloat.
Washington State Univ. mathematicians have designed an encryption code capable of fending off the phenomenal hacking power of a quantum computer. Using high-level number theory and cryptography, the researchers reworked an infamous old cipher called the knapsack code to create an online security system better prepared for future demands.
For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers’ conventional notion that proteins have a static and well-defined structure. It’s thought that mutations in these proteins, known as intrinsically disordered proteins, are associated with neurodegenerative changes, cardiovascular disorders and diseases like cancer.
We live in an increasingly wireless world where self-powered devices are becoming integral to everyday life. A plethora of next-generation wireless technologies are seeing dramatic growth, involving both consumer and industrial applications. Some of the industrial applications include utility meter reading (AMR/AMI), wireless mesh networks, M2M and system control and data acquisition (SCADA) and data loggers, to name a few.
Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water. There are other semiconductors. Gallium arsenide is one such material and it has certain technical advantages over silicon.
