Facebook has said that it has developed facial recognition technology that is capable of telling the difference of two people in side-by-side photos, a technology that is so good, that it is getting very close to replicating human abilities.
The social network has dubbed it DeepFace, and according to the company it's 97.25% accurate, which is a shave from the 97.5% accuracy that humans score on average, in the same standardized test. In order to do that, the technology maps out 3D facial features, after which is makes a flat model that is filtered by color to characterize specific facial elements.
Facebook says it has also taken 4.4 million labeled faces from 4,030 different people on its network to help its system learn. DeepFace won't end up on Facebook right away, instead the social networko is releasing it ahead of presenting it at the IEEE Conference on Computer Vision and Pattern Recognition this June, so that it can get some feedback from the research community.
Time-lapse videos of nature are one of my favorite genres of internet video to watch, especially when shot the right way. A new video released recently by Project Yosemite is just the type of time-lapse that I love. The video features expansive views from deep within Yosemite National Park during both the day and the night. Breathtaking shots of the Sierra Nevada mountain range framed by a very bright and sharp Milky Way take this video above and beyond.
Project Yosemite is a coloration between Colin Delehanty and Sheldon Neill, two videographers who met through Vimeo that decided to shoot the undeniable beauty that is Yosemite National Park. The videos are a compilation of more than 45 days spread over ten months of work to generate the five minute video. The pair hiked over 200 miles to get the shots seen in the video and had to carry more than 70lbs of camera gear with them.
Later on today, scientists will announce a "major discovery" at the Harvard-Smithsonian Center for Astrophysics. There will be a press conference held, which will begin at 11:55am EDT, something you can watch here.
What should we expect to be announced? The Guardian is reporting on speculation that the discovery involves the discovery of primordial gravitational waves, which are ripples in the fabric of spacetime that were produced in the early universe. The imprint they left behind goes back to when the universe was created, some 13.82 billion years ago.
The Guardian said: "The signal is rumoured to have been found by a specialised telescope called Bicep (Background Imaging of Cosmic Extragalactic Polarization) at the south pole." Hiranya Peiris, a Cosmologist from the University College London told The Guardian: "It's been called the Holy Grail of cosmology. It would be a real major, major, major discovery."
NASA welcomes citizen scientists to compete for $35,000 in awards, and public recognition, for those able to successfully help develop improved asteroid identification algorithms.
The first contest in the series will launch on Monday, March 17 - and the Asteroid Grand Challenge Series will have topcoder challenges open to programmers from across the world.
"For the past three years, NASA has been learning and advancing the ability to leverage distributed algorithm and coding skills through the NASA Tournament Lab to solve tough problems," said Jason Crusan, NASA Tournament Lab Director, in a press statement. "We are now applying our experience with algorithm contests to helping protect the planet from asteroid threats through image analysis."
What do you do when a volcano is going off? Well, you'd whip your smartphone out and start recording it, right? Probably not, because of the mass amounts of heat - oh and mortal danger - but what about flying in a drone? This is what Shaun O'Callaghan did, in the video below.
O'Callaghan used a DJI Phantom 2, which is a ready-to-fly (RTF) quadropter, with a gimbal mount and GoPro camera attached. The drone has a flight time of around 25 minutes, enough to capture some gorgeous footage from the exploding volcano. This is an incredible feat, as a normal helicopter could never get this close to an active volcano thanks to the mass heat being pumped out of it, with lava pouring out of vents at temperatures of up to 2192F, or 1200C.
O'Callaghan filmed the footage in Vanuatu, which is a two-hour flight off of the coast of Australia. It's home to some pretty incredible volcano activity.
The United States is the top producing nation of drones, as the Federal Aviation Administration (FAA) tries to come to terms with commercial drone regulation. Industries such as film, farming, and construction now find drones can be a great tool to handle tasks including video recording, mapping geographic sites, and conducting research in remote regions.
There is a global push to bring drones into the commercial market - and Amazon's desire to use drones to deliver packages will need to wait until lawmakers create regulations to fly drones in U.S. airspace.
Since the U.S. has such busy airspace, the FAA is closely studying standards that are right the first time - which means there isn't a big rush to make it happen immediately.
A few years ago a pair of scientists theorized that there was another planet in our solar system orbiting far beyond the orbit of Pluto. The scientists that offered the theory are John Matese and Daniel Whitmire from the University of Louisiana at Lafayette. Both men are physics professors.
Their theory grabbed a lot of attention when it was first published back in 2011. The scientists hoped that when NASA finished combing through the data from its WISE, Wide-field Infrared Survey Explorer, survey that their theory might be proven correct.
NASA is finished with that survey and has announced that it found no proof of Planet X, also known as Tyche. The scientists had theorized that Planet X is a gas giant four times larger than Jupiter and would be found in the Oort cloud.
NASA is always-on the lookout for asteroids that are coming close to the Earth to ensure that we have some warning of one if them is going to hit the planet and to study ones that pass nearby for science. Today an asteroid that is about 90-feet in diameter is going to streak by the planet between the Earth and moon's orbit.
That sounds close if you don't keep in mind the vast distances in space. The asteroid, called 2014 DX110, will be about 217,000 miles from the Earth at its closest point. It is actually very far away from the planet, even though on a cosmic scale this is a close call.
The asteroid will pass the earth at 33,000 mph. At 217,000 miles away from the Earth, it is about 9/10ths of the distance to the moon from the Earth. The asteroid will be at that distance from the planet for about seven hours.
Giant single celled organisms that thawed out from arctic ice and took over mankind use to be a thing only heard of in low-budget, b-grade movies from the 60's and 70's, but the reality is that large viruses frozen in permafrost is a very real reality. Recently, scientist thawed out a block of 30,000-year old permafrost and allowed any viruses that survived to infect the cells of amoebas.
The amoebas used in the study were also a strain found in 30,000 year old permafrost that were reanimated by researchers. When combined with the viruses, the amoeba cells burst, or what is called cellular lysis. When inspected, the burst cells contained a virus that was one of the largest ever discovered and is very similar to a previously discovered ancient virus named Pandoravirus. Due to the similarities and its jug like shape, the new virus was named Pithovirus after a type of amphora used by Pandora.
The Pithovirus contains a genome of just 600,000 DNA bases which is small in terms of modern-day viruses. Extra space inside the virus is consumed by proteins that are needed for the virus to begin replication. Additionally the Pithovirus is only able to encode 467 proteins which is much less than any other giant virus ever discovered.
The use of social media with real-time capability could one day be used to track drug and medical issues, hopefully able to prevent medical outbreaks. Using Twitter analytics and linking the collected information with drug use and geographic data, for example, could allow big data to provide another good tool for medical researchers.
"Ultimately, these methods suggest that we can use 'big data' from social media for remote monitoring and surveillance of HIV risk behaviors and potential outbreaks," said Sean Young, David Geffen School of Medicine assistant professor, in a statement.
There is growing interest among university researchers and the private sector teaming up to monitor medical risk behavior - and to try and predict where a medical outbreak might occur next - though it's still a complicated matter. Of 550 million tweets collected from May 26 to Dec. 9, 2012, researchers found 8,538 tweets related to sexually risky behavior - and more than 1,300 implying stimulant drug use.
