More efficient fuel cells for vehicles: Angling chromium to let oxygen through

More efficient fuel cells for vehicles: Angling chromium to let oxygen through | Nanotechnology Innovations | Scoop.it
More efficient fuel cells might gain wider use in vehicles or as quiet, pollution-free, neighborhood electricity generating stations. A serendipitous finding has resulted in a semiconducting material that could enable fuel cells to operate at temperatures two-thirds lower than current technology, scientists report.

Emotion detectors could make driving safer

Emotion detectors could make driving safer | Nanotechnology Innovations | Scoop.it

Technology now allows us to read facial expressions and identify which of the seven universal emotions a person is feeling: fear, anger, joy, sadness, disgust, surprise, or suspicion. This is very useful in video game development, medicine, marketing, and, perhaps less obviously, in driver safety.

Reducing Anxiety With a Smartphone App - Association for Psychological Science

Reducing Anxiety With a Smartphone App - Association for Psychological Science | Nanotechnology Innovations | Scoop.it

Playing a science-based mobile gaming app for 25 minutes can reduce anxiety in stressed individuals, according to research published in Clinical Psychological Science, a journal of the Association for Psychological Science.

The study suggests that “gamifying” a scientifically-supported intervention could offer measurable mental health and behavioral benefits for people with relatively high levels of anxiety.

New bone-like material is lighter than water but as strong as steel

New bone-like material is lighter than water but as strong as steel | Nanotechnology Innovations | Scoop.it
Materials shape human progress – think stone age or bronze age. The 21st century has been referred to as the molecular age, a time when scientists are beginning to manipulate materials at the atomic level to create new substances with astounding properties.

An old mathematical puzzle soon to be unraveled?

An old mathematical puzzle soon to be unraveled? | Nanotechnology Innovations | Scoop.it

(Phys.org) —It is one the oldest mathematical problems in the world. Several centuries ago, the twin primes conjecture was formulated. As its name indicates, this hypothesis, which many science historians have attributed to the Greek mathematician Euclid, deals with prime numbers, those divisible only by themselves and by one (2, 3, 5, 7, 11, etc.). Under this assumption, there exists an infinite number of pairs of prime numbers whose difference is two, called twin primes (e.g., 3 and 5), but nobody has been able to confirm this so far.

Researchers harness sun’s energy during day for use at night

Researchers harness sun’s energy during day for use at night | Nanotechnology Innovations | Scoop.it

Solar energy has long been used as a clean alternative to fossil fuels such as coal and oil, but it could only be harnessed during the day when the sun’s rays were strongest. Now researchers led by Tom Meyer at the Energy Frontier Research Center at the Univ. of North Carolina at Chapel Hill have built a system that converts the sun’s energy not into electricity but hydrogen fuel and stores it for later use, allowing us to power our devices long after the sun goes down.

A Micro-Muscular Break Through « Berkeley Lab News Center | Nanotechnology Innovations | Scoop.it

Vanadium dioxide is poised to join the pantheon of superstars in the materials world. Already prized for its extraordinary ability to change size, shape and physical identity, vanadium dioxide can now add muscle power to its attributes. A team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length within 60 milliseconds –  faster than the blink of an eye.

Game turning innovation are just around the corner. By annihilating our dependency with power sources will be proven abbreviation. Researchers at National Meeting & Exposition of the American Chemical Society will make this possible. They want to obliterate our conventional techniques in harnessing energy and power. These nanogenerators will change the way we foresee our future. This will be profitable on many levels.

National and Local Influenza Surveillance through Twitter: An Analysis of the 2012-2013 Influenza Epidemic

National and Local Influenza Surveillance through Twitter: An Analysis of the 2012-2013 Influenza Epidemic | Nanotechnology Innovations | Scoop.it

We have found that the accuracy of most social media surveillance systems declines with media attention. This is because media attention increases Twitter “chatter” – tweets that are about the flu but that do not pertain to an actual infection. These messages can mask signs of actual infection. Examples include tweets indicating awareness of flu (e.g. “I hope I don’t get the flu”) and reports of a celebrity’s flu. Disproportionate media attention has similarly resulted in prevalence overestimates in Google Flu Trends, another web-based flu surveillance system [10]. Commonly used Twitter techniques, such as keyword matching or linear regression – which were shown to correlate with CDC data during the 2009 pandemic – have not been strongly correlated with infection data in more recent seasons [9]. The example above illustrates how tweets can be misleading: the message is clearly about the flu but is not about an infection. Previously used techniques do not explicitly attempt to differentiate between chatter and actual infection. The technique presented in this paper successfully filters out tweets that are not reporting influenza infection.

Seeing things: A new transparent display system could provide heads-up data | Nanotechnology Innovations | Scoop.it

Scientists have developed a new approach to produce transparent projection screens...The secret to the new system: Nanoparticles are embedded in the transparent material. These tiny particles can be tuned to scatter only certain wavelengths, or colors, or light, while letting all the rest pass right through. That means the glass remains transparent enough to see colors and shapes clearly through it, while a single-color display is clearly visible on the glass.

Simple mathematical law benchmarks human confrontations : Scientific Reports : Nature Publishing Group | Nanotechnology Innovations | Scoop.it

Many high-profile societal problems involve an individual or group repeatedly attacking another – from child-parent disputes, sexual violence against women, civil unrest, violent conflicts and acts of terror, to current cyber-attacks on national infrastructure and ultrafast cyber-trades attacking stockholders. There is an urgent need to quantify the likely severity and timing of such future acts, shed light on likely perpetrators, and identify intervention strategies. Here we present a combined analysis of multiple datasets across all these domains which account for >100,000 events, and show that a simple mathematical law can benchmark them all.
