Visionary entrepreneur Elon Musk and Facebook chief Mark Zuckerberg were trading jabs on social media over artificial intelligence this week in a debate that has turned personal between the two technology luminaries.



Physicists master unexplored electron property

Tue, 25 Jul 2017 14:24:52 EDT

While the charge and spin properties of electrons are widely utilized in modern day technologies such as transistors and memories, another aspect of the subatomic particle has long remained uncharted. This is the "valley" property which has potential for realizing a new class of technology termed "valleytronics" - similar to electronics (charge) and spintronics (spin). This property arises from the fact that the electrons in the crystal occupy different positions that are quantum mechanically distinct.

Molecular microscopy illuminates molecular motor motion

Tue, 25 Jul 2017 14:13:25 EDT

A toddler running sometimes loses footing because both feet come off the ground at the same time. Kinesin motors that move materials around in cells have the same problem, which limits how fast they can traverse a microtubule in the cell and carry cargo, according to Penn State researchers who have now seen these kinesin motors move using an unusual microscope and tagging method.



Smart surface enables advanced manipulation of droplets

Tue, 25 Jul 2017 14:11:33 EDT

For many years, engineers have sought to create a special kind of surface: one that can both repel and absorb liquids, and whose ability to do so—its "wetting behaviour"—can be quickly and precisely controlled. The technology would have a wide range of potential applications, from water filtration and biomedical devices to liquid optical lenses and lab-on-a-chip systems.



NASA spots a waning Tropical Depression Kulap

Tue, 25 Jul 2017 14:04:48 EDT

Kulap is now a tropical depression moving through the Northwestern Pacific Ocean, and NASA-NOAA's Suomi NPP satellite captured a visible light image of the diminishing storm.



Health commentators say there is a lingering consent problem in biobanking

Tue, 25 Jul 2017 14:00:01 EDT

Researchers throughout the world are going to great lengths to get hold of your genes, tissue and health information. Yet, remarkably, there is very little consensus on how they should be going about doing that. In an essay publishing 25 July in the open access journal PLOS Biology, University of Alberta health law researchers Timothy Caulfield and Blake Murdoch argue that there remains a deep lack of clarity around basic legal and ethical principles surrounding consent, and that these issues are only going to intensify.



Police turn to hackathons as crime fighting goes digital

Tue, 25 Jul 2017 12:31:09 EDT

Police and law enforcement staff are turning to hackathons – collaborative events for developing technology – to come up with new ways of searching for clues within the terabytes of data that many people produce every year.



Freshwater flow affects Everglades fish, but how?

Tue, 25 Jul 2017 12:29:10 EDT

Tue, 25 Jul 2017 12:26:15 EDT

NOAA's GOES-East satellite provided an infrared look at a disorganized Tropical Storm Greg as it continues to weaken and get battered by wind shear in the Eastern Pacific Ocean.



NASA looks at Hurricane Irwin in infrared light

Tue, 25 Jul 2017 12:25:24 EDT

NASA's Aqua satellite passed over Tropical Storm Irwin as it was strengthening toward hurricane status. Aqua gathered temperature data using infrared light that revealed the power building within.



France appeals for help in fighting Cote d'Azur fires

Tue, 25 Jul 2017 12:24:16 EDT

France asked for Europe's help Tuesday in fighting wild fires that have consumed swathes of forest in the southeast, one of which is raging near the popular resort of Saint-Tropez.



Six billion records hacked so far this year: researchers

Tue, 25 Jul 2017 12:19:25 EDT

A surge in computer hacking has led to the breach of more than six billion records so far this year, topping the total for 2016, security researchers said Tuesday.



Colorizing images with deep neural networks

Tue, 25 Jul 2017 12:13:30 EDT

For decades, image colorization has enjoyed an enduring interest from the public. Though not without its share of detractors, there is something powerful about this simple act of adding color to black and white imagery, whether it be a way of bridging memories between the generations, or expressing artistic creativity. However, the process of manually adding color can be very time consuming and require expertise, with typical professional processes taking hours or days per image to perfect. A team of researchers has proposed a new technique to leverage deep networks and AI, which allows novices, even those with limited artistic ability, to quickly produce reasonable results.

Team uses airborne telescopes to study Sun and Mercury during total solar eclipse

Tue, 25 Jul 2017 11:50:01 EDT

A team led by Southwest Research Institute will use airborne telescopes aboard NASA research aircraft to study the solar corona and Mercury's surface during this summer's total solar eclipse. The August 21 observations will provide the clearest images to date of the Sun's outer atmosphere and attempt the first-ever "thermal images" of surface temperature variations on Mercury.



New research reveals potential for synthetic materials systems that can 'count' and sense their size

Tue, 25 Jul 2017 11:49:36 EDT

From the smallest cell to humans, most organisms can sense their local population density and change behavior in crowded environments. For bacteria and social insects, this behavior is referred to as "quorum sensing." Researchers at the University of Pittsburgh's Swanson School of Engineering have utilized computational modeling to mimic such quorum sensing behavior in synthetic materials, which could lead to devices with the ability for self-recognition and self-regulation.



Suomi NPP Satellite sees Hilary on verge of major hurricane status

Tue, 25 Jul 2017 11:47:52 EDT

Cooler cows have healthier calves

Tue, 25 Jul 2017 11:46:40 EDT

Environmental influences affecting cows during pregnancy have been shown to induce life-long physical and metabolic changes in the offspring. To learn more about the effects of heat stress on calves conceived during the summer, Pablo Pinedo, from Colorado State University, and Albert De Vries, from the University of Florida, examined data from more than 150 herds of dairy cattle in Florida, where cows experience hot summers and mild winters.

Tue, 25 Jul 2017 11:38:52 EDT

For most viewers, the Aug. 21, 2017, total solar eclipse will last less than two and half minutes. But for one team of NASA-funded scientists, the eclipse will last over seven minutes. Their secret? Following the shadow of the Moon in two retrofitted WB-57F jet planes.



Researchers demonstrate new way to produce high-density clusters of aligned quantum sensors in diamond

Tue, 25 Jul 2017 11:00:04 EDT

Imagine a sensor so sensitive it can detect changes in the proton concentration of a single protein, within a single cell. This level of insight would reveal elusive quantum-scale dynamics of that protein's function, potentially even in real time, but demands a sensor with controllable features at a similar scale.

A bar magnet creates chaos in plasma

Tue, 25 Jul 2017 11:00:03 EDT

Placing a magnet on your refrigerator might hold up your calendar, but researchers from India's Saha Institute of Nuclear Physics found that placing one outside a plasma chamber causes a localized, fireball-like structure. This work may help understand plasma dynamics under these north-south, or dipolar, magnetic fields. They present their results this week in the journal Physics of Plasmas.
