Amazon billionaire Jeff Bezos is showing off a picture of his Blue Origin space venture’s BE-4 rocket engine going full blast during a hot-fire test in Texas.
“BE-4 continues to rack up time on the test stand,” Bezos said in an Instagram post accompanied by a picture of today’s full-power engine test.
The research and development of neural networks is flourishing thanks to recent advancements in computational power, the discovery of new algorithms, and an increase in labelled data. Before the current explosion of activity in the space, the practical applications of neural networks were limited.
Much of the recent research has allowed for broad application, the heavy computational requirements for machine learning models still restrain it from truly entering the mainstream. Now, emerging algorithms are on the cusp of pushing neural networks into more conventional applications through exponentially increased efficiency.
It’s an intruiging technology. All it takes to set up is burying a sensor in the plant’s dirt, and it works for living and non-living things alike. Given that the experience is going to be wildly different depending on the plant, it’s not like this would be useful for doing anything with accuracy. But for doing weird, unique things (while fondling plants) it’s perfect.
In this era of Kinect, Wii, and Leap, everyone wants to capitalize on motion control. Disney still likes physical peripherals, like houseplants for example.
A short drive south of Alice Springs, the second largest population center in Australia’s Northern Territory, there is a high-security compound, code-named “RAINFALL.” The remote base, in the heart of the country’s barren outback, is one of the most important covert surveillance sites in the eastern hemisphere.
It’s a riddle of cosmic proportions: how can the universe contain stars older than itself?
That’s the conundrum now facing astronomers trying to establish the age of the universe – and its resolution could spark a scientific revolution.
At an international conference held in California last month, there was hope a resolution might be found. Instead, the latest findings only confirmed suspicions there is something fundamentally wrong with current ideas of how the universe works.
The U.S. Army has confirmed it is trying to speed up high-powered laser weapon program to develop a new system that will acquire, track, engage, and defeat unmanned aircraft system, cruise missile and rocket, artillery, and mortar threats.
The new Army’s high-powered laser weapon system is intended to provide 360º protection and simultaneously engage threats arriving from different azimuths.
The Army will adjust the current High Energy Laser Tactical Vehicle Demonstrator (HEL-TVD), a 100 kW-class laser system integrated on a Family of Medium Tactical Vehicles platform developed by Dynetics and subcontractor Lockheed Martin. Under the new directed energy strategy, the Army is leveraging progress made in that effort in order to merge the HEL-TVD with similar technologies in development by the Navy and the Office of the Secretary of Defense.
SELF-RENEWAL Fluorescent markers reveal which genes are turned on as hydras’ stem cells develop into specific cell types. For instance, nerve cells light up magenta in one hydra (second from left). Another (second from right) shows gene activity behind two of the stages of development (early, green; late, red) of the animal’s stinging cells.
The question of what sets humans apart from other animals is one of the oldest philosophical puzzles. A popular answer is that only humans can understand that others also have minds like their own.
But new research suggests that ravens — birds singled out by many cultures as a symbol of intelligence and wisdom — share at least some of the human ability to think abstractly about other minds, adapting their behavior by attributing their own perceptions to others.
The study, “Ravens Attribute Visual Access to Unseen Competitors,” was published Feb. 2 in Nature Communications. It found that ravens guarded caches of food against discovery in response to the sounds of other ravens if a nearby peephole was open, even if they did not see another bird. They did not show the same concern when the peephole was closed, despite the auditory cues.
