Whether society embraces face recognition on a larger scale will ultimately depend on how legislators, companies and consumers resolve the argument about its singularity. Is faceprinting as innocuous as photography, an activity that people may freely perform? Or is a faceprint a unique indicator, like a fingerprint or a DNA sequence, that should require a person's active consent before it can be collected, matched, shared or sold?
Dr. Atick is firmly in the second camp. -
Actually these sort of things are also quite easy to exploit. Print a picture of Osama bin Laden on your t-shirt and have the entire police force scared out of their wits.

I saw so many bin laden t-shirts already ... they must have better filters than this
New apps allow smartphone users to join the hunt for ultrahigh-energy cosmic rays - 0 views
-
Two apps - the Distributed Electronic Cosmic-ray Observatory (DECO) and Cosmic Rays Found in Smartphones (CRAYFIS) - transform smartphones into miniature cosmic-ray detectors. They use the CMOS chips inside phones' onboard cameras to detect the secondary particles produced when cosmic rays - energetic, charged subatomic particles arriving from beyond the solar system - collide with air molecules in the Earth's atmosphere
NASA Vesta Trek - 2 views

NASA Releases Tool Enabling Citizen Scientists to Examine Asteroid Vesta Vesta Trek is a free, web-based application that provides detailed visualizations of Vesta, one of the largest asteroids in our solar system. NASA's Dawn spacecraft studied Vesta from July 2011 to September 2012. Data gathered from multiple instruments aboard Dawn have been compiled into Vesta Trek's user-friendly set of tools, enabling citizen scientists and students to study the asteroid's features. The application includes: -- Interactive maps with the ability to overlay a growing range of data sets including topography, mineralogy, abundance of elements and geology, as well as analysis tools for measuring the diameters, heights and depths of surface features and more. -- 3-D printer-exportable topography so users can print physical models of Vesta's surface. -- Standard keyboard gaming controls to manoever a first-person visualization of "flying" across the surface of the asteroid. "There's nothing like seeing something with your own eyes, but these types of detailed data-visualizations are the next best thing," said Kristen Erickson, Director, Science Engagement and Partnerships at NASA Headquarters in Washington DC.
Engineering three-dimensional hybrid supercapacitors for high-performance integrated energy storage - 3 views
-
Stacking laser printed supercapacitors (no clean room required btw) has lead to about 1100F/g and thus about 20-40Wh/L. For supercapacitors thats pretty damn good. For reference, Li-ion recently reached 650Wh/L. The gap is closing, although for supercaps of this type the theoretical maximum is 1400F/g.
'Sewing' with molten glass and maths - BBC News - 1 views
-
From the section Science & Environment US researchers have developed what they call a "molten glass sewing machine" by combining 3D printing of glass with a mathematical model of how a liquid thread forms different types of loop. When the nozzle releasing a stream of molten glass is raised above a certain level, that thread begins to wobble.
Dynamic flat lens with metasurface actuated with MEMS - 2 views
-
Great engineering feat from Capasso's idea - an integrated flat lens electrically controlled enabling dynamic beam steering. Reconfigurabilility is the aim. The lens can be used microscope systems, holographic and projection imaging, LIDAR and laser printing. Besides working now on the mid-IR, visible light is the target.
