Google Launches Augmented Reality App ARCore For Android | #AR #RA 

Google Launches Augmented Reality App ARCore For Android | #AR #RA  | Sciences, l'Espace, le Temps et le Monde | Scoop.it
Google has launched its own augmented reality kit for developers, called ARCore, a lighter version of the company’s Tango platform that does not require any specialized hardware to run.

ARCore is a light software development kit, similar to Apple’s ARkit, which is able to track motion, understand flat surfaces, and estimate where the light will be for accurate shadows.

See Also: Glass restarted after two years in the dark

The SDK is currently available on Android 7.0 Nougat and its successor Android Oreo. It will work on the Google Pixel and the Samsung Galaxy S8 and S8 Plus. Google is aiming for 100 million supported devices by the end of the year, according to The Verge.

Google has been working on Project Tango for three years now, launching specialized smartphones with Lenovo and Asus. The devices had depth perception functionality, because of the dual-cameras, creating the “six degrees of freedom” found on high-end virtual reality (VR) headsets.

Borders and the Arctic Ocean

The ice in the Arctic is disappearing. Melting Arctic ice means new economic opportunities: trade routes in the Arctic ocean, and access to natural resources. Because of this, the Arctic nations are now moving to expand their border claims. Russia has shown that it’s the most ambitious, using a potent combination of soft power and military buildup to advance its agenda. They’ve said the Arctic is rightfully theirs.

Matt Manish's curator insight, February 16, 10:31 PM
Since the 1980's a significant amount of ice in Antarctic ocean has melted away. This is a big deal because this is causing the changing of borders in this part of the world. With all the ice melting in Antarctica, this opens up new shipping lanes with much faster routes. This also makes it much easier for to drill for natural resources such as gas and oil, that were once difficult to get to because they were covered in ice. This is causing countries like Russia, Canada, Finland, and others to desire for new borders to be drawn up, hopefully in favor of their nation. Russia has even started developing military bases on some of the coast line that is opening up in Antarctica. It will be interesting to see how the borders in the Arctic circle are going to change and how it will also effect world trade in that part of the world.

In this video, Vox Borders looks into who owns the Arctic. Because of the significant melting ice, the water ways of the Arctic may be opening up… this video looks into the efforts that Russia has made to declare the region. For example, off the coast of Russia, near the north pole lies a mining town, that was established to make sure Russia has a spot that they can declare as their own in the Arctic.

AI system can automatically diagnose heart disease from scans

AI system can automatically diagnose heart disease from scans | Sciences, l'Espace, le Temps et le Monde | Scoop.it
The AI, called Ultromics, is being used at John Radcliffe hospital in Oxford. The system has been successful in the early trials could soon be available for free on the NHS.

 

Currently cardiologists can tell if there is a problem from the timing of the heartbeat in scans. But sometimes they get it wrong. There are 60,000 heart scans carried out each year and 12,000 of these are misdiagnosed. 

 

Ultromics was developed by Professor Paul Leeson as a way of improving those figures.  He taught the AI system how to recognise heart disease by feeding it 1,000 heart scans of patients from the last seven years. Information about whether the patient went on to develop heart problems was also provided. 

 

The AI software used this information as a baseline to predict and diagnose the scans of new patients.  It is only being used to provide recommendations to doctors which they can then follow up with their own diagnosis. The technology has already been tested in six cardiology units and the results of the study are to be published later this year.

This AI can read your mind: AI software creates images based on pictures you are looking at

This AI can read your mind: AI software creates images based on pictures you are looking at | Sciences, l'Espace, le Temps et le Monde | Scoop.it

Japanese scientists have create a creepy machine that can peer into your mind's eye with incredible accuracy. The AI studies electrical signals in the brain to work out exactly what images someone is looking at, and even thinking about.  The technology opens the door to strange future scenarios, such as those portrayed in the series 'Black Mirror', where anyone can record and playback their memories.

 

 

Chilling Black Mirror-style machine recreates the image you're thinking about by decoding your brain signals.  The breakthrough relies on neural networks, which try to simulate the way the brain works in order to learn.  These networks can be trained to recognize patterns in information - including speech, text data, or visual images - and are the basis for a large number of the developments in AI over recent years. They use input from the digital world to learn, with practical applications like Google's language translation services, Facebook's facial recognition software and Snapchat's image altering live filters. 

 

The Kyoto team's deep neural network was trained using 50 natural images and the corresponding fMRI results from volunteers who were looking at them. This recreated the images viewed by the volunteers. They then used a second type of AI called a deep generative network to check that they looked like real images, refining them to make them more recognizable.

The exciting thing for me is that, to some extent, the same image produces the same type of recognisable response in different brains. Was Kant right about the "a priori" knowledge from our senses?

Strange Nuclear Sphere Could Revolutionize Fusion Energy

Strange Nuclear Sphere Could Revolutionize Fusion Energy | Sciences, l'Espace, le Temps et le Monde | Scoop.it

It's well established that nuclear fusion - the reaction that powers our Sun - could be the key to unlocking clean, limitless energy here on Earth. But one of the biggest challenges of modern science is how to harness the fusion reaction so that it produces more energy than it consumes. And a new paper claims to have found a way to do just that.

 

Instead of looking at how to optimize common fusion reactor designs, such as tokamaks or stellerators, a group of physicists experimentally tested some novel reactor types. They found that a strange-looking sphere design could be the key to achieving net-positive nuclear fusion because, surprisingly, it has the potential to generate more energy than it uses. 

 

The key difference, aside from its shape, is that this nuclear sphere would fuse hydrogen and boron, rather than hydrogen isotopes such as deuterium and tritium. And it uses lasers to heat the core up to 200 times hotter than the centre of the Sun.

 

If the team's calculations are correct, the hydrogen-boron reactor device could be built and producing net-positive energy way before any of the reactors currently being tested reach completion. Even better, the hydrogen-boron reaction produces no neutrons, and therefore doesn't create any radioactive waste as a byproduct.

"It is a most exciting thing to see these reactions confirmed in recent experiments and simulations," says lead researcher Heinrich Hora, from the University of New South Wales in Australia.

In Silico Flurries: How a Snowflake Grows

In Silico Flurries: How a Snowflake Grows | Sciences, l'Espace, le Temps et le Monde | Scoop.it

In “The Chemical Basis of Morphogenesis,” Alan Turing proposed that chemical substances (morphogens) can transform and spread through tissue to yield natural patterns—stripes, spots and spirals—seen on animals. Turing expressed this idea in the language of differential equations, whose initial conditions controlled the evolution of the patterns.

 

The complexity and detail in the patterns from such reaction-diffusion systems can be truly surprising—a relatively simple process and small number of parameters can yield an endless variety of familiar patterns and shapes. One season-appropriate example of this is snowflakes, known for their variety and complexity.

Tabby's Star: Alien megastructure not the cause of dimming of the 'most mysterious star in the universe'

Tabby's Star: Alien megastructure not the cause of dimming of the 'most mysterious star in the universe' | Sciences, l'Espace, le Temps et le Monde | Scoop.it
Scientists are one step closer to solving the mystery behind the 'most mysterious star in the universe.'

 

A team of more than 200 researchers, including Penn State Department of Astronomy and Astrophysics Assistant Professor Jason Wright and led by Louisiana State University's Tabetha Boyajian, is one step closer to solving the mystery behind the "most mysterious star in the universe." KIC 8462852, or "Tabby's Star," nicknamed after Boyajian, is otherwise an ordinary star, about 50 percent bigger and 1,000 degrees hotter than the Sun, and about than 1,000 light years away. However, it has been inexplicably dimming and brightening sporadically like no other. Several theories abound to explain the star's unusual light patterns, including that an alien megastructure is orbiting the star.

 

The mystery of Tabby's Star is so compelling that more than 1,700 people donated over $100,000 through a Kickstarter campaign in support of dedicated ground-based telescope time to observe and gather more data on the star through a network of telescopes around the world. As a result, a body of data collected by Boyajian and colleagues in partnership with the Las Cumbres Observatory is now available in a new paper in The Astrophysical Journal Letters.

 

"We were hoping that once we finally caught a dip happening in real time we could see if the dips were the same depth at all wavelengths. If they were nearly the same, this would suggest that the cause was something opaque, like an orbiting disk, planet, or star, or even large structures in space" said Wright, who is a co-author of the paper, titled "The First Post-Kepler Brightness Dips of KIC 8462852." Instead, the team found that the star got much dimmer at some wavelengths than at others.

 

"Dust is most likely the reason why the star's light appears to dim and brighten. The new data shows that different colors of light are being blocked at different intensities. Therefore, whatever is passing between us and the star is not opaque, as would be expected from a planet or alien megastructure," Boyajian said.
