Around the world, cities are choking on smog. But a new AI system plans to analyze just how bad the situation is by aggregating data from smartphone pictures captured far and wide across cities.

The project, called AirTick, has been developed by researchers from Nanyang Technological University in Singapore, reports New Scientist. The reasoning is pretty simple: Deploying air sensors isn’t cheap and takes a long time, so why not make use of the sensors that everyone has in their pocket?

The result is an app which allows people to report smog levels by uploading an image tagged with time and location. Then, a machine learning algorithm chews through the data and compares it against official air-quality measurements where it can. Over time, the team hopes the software will slowly be able to predict air quality from smartphone images alone.

It’s looking less likely that a swarm of comets or an “alien megastructure” can explain a faraway star’s strange dimming.

The star (nicknamed “Tabby’s Star,” after its discoverer, Tabetha Boyajian) made major headlines last October when Jason Wright, an astronomer at Pennsylvania State University, suggested that it could be surrounded by some type of alien megastructure. A more likely idea — one that’s far less exciting — is that the star is orbited by a swarm of comets. But scientists can’t be sure either way.

Now, Bradley Schaefer, an astronomer at Louisiana State University, has probed the star’s behavior over the past century by looking at old photographic plates. Not only does the star’s random dipping date back more than a century, but it also has been gradually dimming over that period — a second constraint that makes it even harder to explain.

One way or another, via government research or the countless new startups, fusion is well on it’s way.

Chinese scientists have managed to create a hydrogen gas that is three times hotter than the sun.

The artificial solar energy could eventually be used as an inexhaustible source of power, ending reliance on fossil fuels and solving the world energy crisis.

Sooner or later it IS going to happen. All we can do is prepare to defend out planet, whilst making sure we have humans living off-world, somewhere, so that all of our proverbial eggs aren’t in one proverbial basket!

But don’t worry, it won’t hit us.

Physicists have been buzzing (or rather, tweeting) about the possibility that the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment finally discovered gravitational waves. LIGO has been searching for these cosmic ripples for over a decade. Last September, it upgraded to Advanced-LIGO, a more sensitive system that’s also better at filtering out noise. Advanced-LIGO has a much stronger chance of collecting concrete evidence of gravitational waves—if it hasn’t already.

Scientists may be excited, but talk of gravitational waves leaves most people scratching their heads. What are these cosmic vibrations, and why are they making waves in the scientific community?

Just last week, we reported that Germany’s revolutionary nuclear fusion machine managed to heat hydrogen gas to 80 million degrees Celsius, and sustain a cloud of hydrogen plasma for a quarter of a second. This was a huge milestone in the decades-long pursuit of controlled nuclear fusion, because if we can produce and hold onto hydrogen plasma for a certain period, we can harness the clean, practically limitless energy that fuels our Sun.

Now physicists in China have announced that their own nuclear fusion machine, called the Experimental Advanced Superconducting Tokamak (EAST), has produced hydrogen plasma at 49.999 million degrees Celsius, and held onto it for an impressive 102 seconds.

While this is nowhere near the hottest temperature that’s been produced by an experiment — that honour goes to the Large Hadron Collider, which hit a whopping 4 trillion degrees Celsius (250,000 times hotter than the centre of the Sun) back in 2012 — the team from China’s Institute of Physical Science in Hefei managed to recreate solar conditions for well over a minute.

Australian scientists hope that a tiny device just 3cm long and a few millimetres wide will enable paralysed patients to walk again by allowing them to control bionic limbs with the power of subconscious thought.

The new device, dubbed the “bionic spine”, is the size of a small paperclip and will be implanted in three patients at the Royal Melbourne hospital in Victoria next year. The participants will be selected from the Austin Health spinal cord unit, and will be the first humans to trial the device, which so far has only been tested in sheep.

Doctors will make a tiny cut in the neck of the patients and feed a catheter containing the bionic spine up through the blood vessels leading into the brain, until it rests on top of the motor cortex, the part of the brain where nerve impulses that initiate voluntary muscle movements come from. The catheter will then be removed, leaving the bionic spine behind.

Another step forward for Quantum — The Quantum Current. US Dept. of Energy has a new method to generate very low-resistance electric (Quantum) current which will improve our methods for energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity—the ability of some materials (zirconium pentatelluride) to carry current with no energy loss.

Me and one of my friends on LinkedIn both knew it was only a matter of time that AI & Quantum together would be announced. And, Google with D-Wave indeed would be leading this charge. BTW — once this pairing of technologies is done; get ready for some amazing AI technology including robotics to come out.

But there may not be any competitors for a while if Google’s “Ace of Spades” newbie performs as they predict. According to Hartmut Neven, head of its Quantum Al Lab, this baby can run:

“We found that for problem instances involving nearly 1,000 binary variables, quantum annealing significantly outperforms its classical counterpart, simulated annealing. It is more than 10 to the power of 8 times faster than simulated annealing running on a single core.”
