Stunning Reindeer Migration Captured by Drone
Haven't you herd it's not Christmas anymore? It seems this bunch of reindeer have only just got the message after they were spotted staggering back to Santa's.
NASA | Best-Ever View of the High-Energy Gamma-ray Sky - 4K
This image, constructed from more than six years of observations by NASA's Fermi Gamma-ray Space Telescope, is the first to show how the entire sky appears at energies between 50 billion (GeV) and 2 trillion electron volts (TeV).
A diffuse glow fills the sky and is brightest in the middle of the map, along the central plane of our galaxy. The famous Fermi Bubbles, first detected in 2010, appear as red extensions north and south of the galactic center and are much more pronounced at these energies. Discrete gamma-ray sources include pulsar wind nebulae and supernova remnants within our galaxy, as well as distant galaxies called blazars powered by supermassive black holes. Labels show the highest-energy sources, all located within our galaxy and emitting gamma rays exceeding 1 TeV.
Major improvements to methods used to process observations from NASA's Fermi Gamma-ray Space Telescope have yielded an expanded, higher-quality set of data that allows astronomers to produce the most detailed census of the sky yet made at extreme energies. This new sky map reveals hundreds of these sources, including 12 that produce gamma rays with energies exceeding a trillion times the energy of visible light. The survey also discovered four dozen new sources that remain undetected at any other wavelength. The improved data, known as Pass 8, effectively sharpens the Large Area Telescope's (LAT) view while also significantly widening its useful energy range.
Using 61,000 Pass 8 gamma rays collected over 80 months, Marco Ajello and his colleagues constructed a map of the entire sky at energies ranging from 50 billion (GeV) to 2 trillion electron volts (TeV). For comparison, the energy of visible light ranges from about 2 to 3 electron volts.
The Fermi team cataloged 360 individual gamma-ray sources, about 75 percent of which are blazars -- distant galaxies sporting jets powered by supermassive black holes. The highest-energy sources, which are all located within our galaxy, are mostly the remnants of supernova explosions and pulsar wind nebulae, places where rapidly rotating neutron stars accelerate particles to near the speed of light.
A famous example, the Crab Nebula, tops the list of the highest-energy Fermi sources, producing a steady drizzle of gamma rays exceeding 1 TeV.
Astronomers think these very high-energy gamma rays are produced when lower-energy light collides with accelerated particles. This results in a small energy loss for the particle and a big gain for the light, transforming it into a gamma ray.
For the first time, Fermi data now extend to energies previously seen only by ground-based detectors. Because ground-based telescopes have much smaller fields of view than the LAT, which scans the whole sky every three hours, they have detected only about a quarter of the objects in the new catalog. This study provides ground facilities with more than 280 new targets for follow-up observations.

Space and Time into a single Continuum
Eleven dimensions, parallel universes, and a world made out of strings? It's not science fiction, it's string theory. Bestselling author and physicist Brian Greene offers a tour of this seemingly strange world in "The Elegant Universe," a three-hour Peabody Award-winning miniseries.
Part 1, "Einstein's Dream," introduces string theory and shows how modern physics—composed of two theories that are ferociously incompatible—reached its schizophrenic impasse: One theory, general relativity, successfully describes big things like stars and galaxies, while another, quantum mechanics, is equally successful at explaining small things like atoms and subatomic particles. Albert Einstein, the inventor of general relativity, dreamed of finding a single theory that would embrace all of nature's laws. But in this quest for the so-called unified theory, Einstein came up empty-handed, and the conflict between general relativity and quantum mechanics has stymied all who've followed. That is, until the discovery of string theory.

This is the most amazing drone we've seen yet
The Inspire One drone looks cool flying and offers a ton of new features, including a 360 degree camera that records in 4K.
Read more: http://www.theverge.com/2014/11/12/72...
The drone game has changed. That may sound like hyperbole, but that was my first impression when experiencing the DJI Inspire One. This is a unit that anyone could pick up and learn to fly quickly, just as you could with the DJI Phantom. But it offers a ton of powerful new features that were previously only available in units too big, dangerous, and expensive for the average consumer to own.
Watching the Inspire One take off and land is exciting, because it transforms mid-flight, with the legs folding up after takeoff so you can shoot 360 degrees of unobstructed video. The unit also has a ground-facing camera that can track what's below and keep the unit stabilized, even when there is no GPS signal, making it much easier to fly indoors.

Leia Display System - promo video HD short version
The Leia Display System is a patented screen enabling mid air image projection. This system, based on computer technologies and aerodynamic solutions, makes it possible to display random multimedia content on a thin, virtually invisible, mist-like surface. Furthermore, the Leia Display System actively responds to touch. This allows interaction with the projected images, using movement and gestures.

3D Object Manipulation in a Single Photograph using Stock 3D Models: Full Length Video
We present an approach that allows users to perform 3D manipulations, such as rotations, translations, scaling, deformation, and 3D copy-paste, to objects in photographs. Our approach seamlessly reveals hidden parts of objects in photographs, and produces plausible shadows and shading. To reveal hidden parts, we use publicly available 3D models to complete missing geometry and appearance. As input, the user provides a photograph, together with a 3D model obtained using a word search on a public repository, and an object-free background filled in using in-painting techniques. Using our approach, users can create artistic compositions, manipulate vintage photographs, and even create animations.

Flower Pot Fridge!
The world's cheapest and easiest refrigerator to make, it uses minimal resources and runs completely without electricity. It's called a zeer pot, or the pot-in-pot and was rebirthed by Mohammed Bah Abba, who put the laws of thermodynamics to work for mankind.
The zeer pot, is just two simple pots, one pot smaller than the other.
The smaller pot is put inside the bigger pot, and we fill the space between with sand. We wet the sand twice a day and cover the top with a wet towell to keep warm air from entering the interior.
Things You'll Need:
Two clay (terracotta) pots, one larger than the other
Sand
Water
Cloth to cover the pots
Clay, cork or other material to plug holes in the pots

Type-Hover-Swipe in 96 Bytes: A Motion Sensing Mechanical Keyboard
Project website:
http://research.microsoft.com/en-us/p...
We present a new type of augmented mechanical keyboard, capable of sensing rich and expressive motion gestures performed both on and directly above the device. Our hardware comprises of low-resolution matrix of infrared (IR) proximity sensors interspersed between the keys of a regular mechanical keyboard. This results in coarse but high frame-rate motion data. We extend a machine learning algorithm, traditionally used for static classification only, to robustly support dynamic, temporal gestures. We propose the use of motion signatures a technique that utilizes pairs of motion history images and a random forest based classifier to robustly recognize a large set of motion gestures on and directly above the keyboard. Our technique achieves a mean per-frame classification accuracy of 75.6% in leave-one-subject-out and 89.9% in half-test/half-training cross-validation. We detail our hardware and gesture recognition algorithm, provide performance and accuracy numbers, and demonstrate a large set of gestures designed to be performed with our device. We conclude with qualitative feedback from users, discussion of limitations and areas for future work.

This beautiful American contra luz opal stone weighs approximately 119.0 carats and measures 46.0 x 44.0 x 10.1mm (1.81 x 1.73 x 0.39 in). It was found in Opal Butte, Oregon. What makes this piece really unique is the brown nebula-like cluster formed inside it. Contra luz opals are similar to crystal opals, which means they are transparent, but have this ability to also create color flash when light passes through from the opposite side.
