Last month the Federal Aviation Administration made a decision that marks a significant step for the commercial drone industry, permitting six movie and television production companies the right to use drones. This is the first time the FAA has allowed this type of industry exemption from the rules that prohibit drones from flying in U.S. airspace. Despite Congress' request that it develop standards in support of safe drone use by September 2015, and despite corporate America's campaigning for drone operations, the FAA has been dragging its feet. Thanks to Hollywood and the broader entertainment industry, a door has been opened for commercial drones.

The same can be said about the world of science, which witnessed some of the biggest breakthroughs in decades, even as it provided several grim reminders about the impact of climate change on planet Earth. One hundred years ago, Albert Einstein predicted that the collision of massive objects such as black holes and neutron stars can create "ripples" in the curvature of space-time. Earlier this year, scientists associated with the Laser Interferometer Gravitational-Wave Observatory (LIGO) discovered these distortions. "The achievement fulfilled a 100-year-old prediction, opened up a potential new branch of astronomy, and was a stunning technological accomplishment," the journal Science, which was one of the many publications that termed the discovery of gravitational waves "Breakthrough of the Year," said in a recent statement. Currently, all we know about the cosmos is what we have gathered from electromagnetic radiation such as radio waves, visible light, infrared light, X-rays and gamma rays.

There was a primitive ocean on Mars that held more water than our Artic Sea and alien hunters believe to have spotted signs that life once inhabited the ancient sea. Nestled in the dust of the Gusev crater, appears to be a round broken sea shell that could be'evidence of Mars having an ocean with living creatures'. This is the second sighting of a sea shell this week and, combined with the fossilized fish seen in the dust, conspiracy theorists believe this is proof life did in face exist on the red planet. Nestled in the Gusev crater appears to be a round broken shell that could be'evidence of Mars having an ocean with living creatures' seen in images from the Nasa Curiosity Rover. Pareidolia is the psychological response to seeing faces and other significant and everyday items in random stimulus.

Professor Stephen Hawking says he believes pollution and human "stupidity" remain the biggest threats to mankind, while also expressing his concerns over the use of artificial intelligence in warfare. The world's leading theoretical physicist argued "we have certainly not become less greedy or less stupid" in our treatment of the environment over the past decade, during an interview on Larry King Now, which is hosted on Ora TV. Professor Hawking said: "Six years ago, I was warning about pollution and overcrowding, they have gotten worse since then. The population has grown by half a billion since our last interview, with no end in sight. "At this rate, it will be eleven billion by 2100.

Finding water on Mars has been a dream of scientists for decades and could prove an essential resource for any human pioneers looking to colonise the red planet. Now Nasa is hoping its Curiosity Rover may finally be able to settle the question of whether the liquid still exists on the planet's surface. Scientists are dispatching the robot to explore a feature on a sandy hillside they believe could be their best chance yet of finding water on the red planet. Scientists are hoping to send the Curiosity Rover to investigate dark streaks that appear on the nearby Mount Sharp during the Martian summer. Last year Nasa confirmed'dark fingers' spotted by the Mars Reconnaissance Orbiter were likely to be made by liquid moving across the planet's surface.

Once a year, when Slava Epstein was growing up in Moscow, his mother took him to the Exhibition of the Achievements of the National Economy, a showcase for the wonders of Soviet life. The expo featured many things--from industrial harvesters to Uzbek wine--but Epstein, who began going in the nineteen-sixties, when he was eight or nine, was interested primarily in one: the Cosmos Pavilion, a building the size of a hangar, with a ceiling shaped like a giant inverted parabola. Space fever was running high in the city. Since 1961, when Yuri Gagarin orbited the globe, unmanned vessels had been launched toward Mars and Venus. Beside the expo's entrance, the towering Monument to the Conquerors of Space depicted a probe swooping up to the heavens. The Pavilion displayed futuristic technology--Vostok rockets and Soyuz orbiters--but Epstein was less interested in the glories of advanced thruster design than in the glories of space. He wanted to devote himself to astronomy. When a textbook that he found on the topic began with algebraic formulas, he prodded his older brother to explain them. During high school, he enrolled in classes in physics and math at Moscow State University. His parents disapproved of his desired career: because he is half Jewish, Epstein would face harsh Soviet quotas limiting Jews in the study of physics, a field deemed relevant to national security. But after his first lecture the professor invited him for a walk, and affirmed what they had been saying all along. "Don't do it," he warned. Soviet Russia may have been a fatalist's paradise, but from a young age Epstein felt that he was hardwired for optimism. He convinced himself that what is truly important in science is the ability to connect ideas, no matter the field, and so he took up biology. Rather than telescopes, he would use microscopes, which he began taking with him on trips to the White Sea, near the Arctic Circle, to study protozoa along the shore--research that could be conducted with minimal state interference. Over time, he grew interested in even smaller, more ancient forms of life: bacteria. Studying microbes inevitably causes a reordering of one's perceptions: for more than two billion years, they were the only life on this planet, and they remain in many ways its dominant life form. To a remarkable extent, the microbial cosmos was less explored than the actual cosmos: precisely how the organisms evolve, replicate, fight, and communicate remains unclear. Nearly all of microbiology, Epstein eventually learned, was built on the study of a tiny fraction of microbial life, perhaps less than one per cent, because most bacteria could not be grown in a laboratory culture, the primary means of analyzing them. By the time he matured as a scientist, many researchers had given up trying to cultivate new species, writing off the majority as "dark matter"--a term used in astronomy for an inscrutable substance that may make up most of the universe but cannot be seen.

Humans become aroused when touching robots in sensitive places, a new study has found. Far from seeing robots as just computers, humans can become physiologically aroused from touching a human-shaped robot in private places like their eyes and buttocks, the Stanford study found. The results could have huge consequences for the creation of robots in the future, such as ones that people live or even have sex with. It might also help people create "robot stand-ins", that allow people to touch others when actually being there isn't an option, the researchers said. Scientists have taken a leaf out of the script of The Martian by showing how easy it would be to grow your own veg on the Red Planet.

Designing a covariance function that represents the underlying correlation is a crucial step in modeling complex natural systems, such as climate models. Geospatial datasets at a global scale usually suffer from non-stationarity and non-uniformly smooth spatial boundaries. A Gaussian process regression using a non-stationary covariance function has shown promise for this task, as this covariance function adapts to the variable correlation structure of the underlying distribution. In this paper, we generalize the non-stationary covariance function to address the aforementioned global scale geospatial issues. We define this generalized covariance function as an intrinsic non-stationary covariance function, because it uses intrinsic statistics of the symmetric positive definite matrices to represent the characteristic length scale and, thereby, models the local stochastic process. Experiments on a synthetic and real dataset of relative sea level changes across the world demonstrate improvements in the error metrics for the regression estimates using our newly proposed approach.

This paper presents a new method for estimating high dimensional covariance matrices. The method, permuted rank-penalized least-squares (PRLS), is based on a Kronecker product series expansion of the true covariance matrix. Assuming an i.i.d. Gaussian random sample, we establish high dimensional rates of convergence to the true covariance as both the number of samples and the number of variables go to infinity. For covariance matrices of low separation rank, our results establish that PRLS has significantly faster convergence than the standard sample covariance matrix (SCM) estimator. The convergence rate captures a fundamental tradeoff between estimation error and approximation error, thus providing a scalable covariance estimation framework in terms of separation rank, similar to low rank approximation of covariance matrices. The MSE convergence rates generalize the high dimensional rates recently obtained for the ML Flip-flop algorithm for Kronecker product covariance estimation. We show that a class of block Toeplitz covariance matrices is approximatable by low separation rank and give bounds on the minimal separation rank $r$ that ensures a given level of bias. Simulations are presented to validate the theoretical bounds. As a real world application, we illustrate the utility of the proposed Kronecker covariance estimator for spatio-temporal linear least squares prediction of multivariate wind speed measurements.
