The price could spike again.

The Chinese government will end bitcoin mining operations in the coming months, Bloomberg reported over this January, a move that could have a massive impact on the price of the world’s biggest digital currency.

China has been a central player in the development of bitcoin in recent years, but Beijing has spent the last six months cracking down on the cryptocurrency industry — shutting down local exchanges and banning initial coin offerings.

Leaked documents suggest the Chinese government plans an “orderly exit” for bitcoin mining operations in the coming weeks and months.

‘Freeze… and marry me!’ – Russians who propose at gunpoint

146FB4A5-84B1-439D-9682-3555A21C005B

Anastasia is expecting her boyfriend Sergei to be waiting for her when her flight arrives at St Petersburg airport.

But as she lands he texts to say that, due to unforeseen work commitments, a friend will be picking her up instead.

So far, so normal.

Later, as Anastasia is approaching her apartment building in the friend’s car, a minibus with blacked-out windows screeches into their path. Armed men in masks jump out and take her driver friend away.

Anastasia is led to the back of the car she was travelling in. The men begin rifling through her things in the boot and discover a small packet full of white powder.

Surrounded by men clad in black special ops uniforms, a female plain-clothes detective turns to her: “You’re suspected of supplying banned substances.”

The colour in Anastasia’s face swiftly drains away.

“You must be mistaken. That’s not mine,” she says, smiling nervously.

“Then whose is it? Enough of the games!” a man barks.

The questions continue, until the man opens the packet to reveal a small pink box.

“And what’s this?” he asks.

“No idea!” she replies, her voice breaking.

Suddenly the man gets down on one knee, rips off his mask and shouts: “Marry me!”

It’s Sergei, and it turns out he’s the only one here who actually works in law enforcement. The others work for an “extreme proposal” service – part of an industry established in Russia in recent years.

How 5G will reinvent “working from home”

009749CF-FD33-423E-8A99-719F346AC5BC

It’s 10:00 am. Do you know where your employee is? No doubt they are working—somewhere.

Thanks to greatly improved internet connectivity and workforce applications, employees in an increasing number of professions can work just about anywhere they want—in their home, at a coffee shop, on a plane. And chances are they’re more productive and more engaged than they would be if they were in the office. They may even be planning to stay in their job longer because of their flexible work location. In 2017, Stanford economics professor Nicholas Bloom, in a TED Talk, went so far as to call work-from-home potentially as innovative as the driverless car.

Now, work-from-home is itself about to be disrupted, by the coming of 5G and its ability to enable virtual reality (VR) anywhere through what’s known as XR, the combination of extended, augmented, virtual, and mixed reality technologies. Fifth-generation (5G) communications networks, with their exponentially faster connection speeds, capacity, and communication response times (known as latency), will make possible an astonishing range of innovative new products and services.

Thermoelectric generator harvests renewable energy from the cold of space

1522C4FB-803E-4843-A78B-CF942B00FAD6

The thermoelectric generator uses a black aluminum disk to radiate heat into the atmosphere, and a polystyrene enclosure to keep the air inside warm.Aaswath Raman

 As effective as solar panels are, one of their major downsides is that they only produce power during the day, so excess energy needs to be stored for use overnight. But now, engineers from the University of California, Los Angeles (UCLA) have developed a prototype device that works almost the opposite way, harvesting energy from the cold night sky to passively power an LED.

The device works on the thermoelectric principle, where an electric current is created through the temperature difference between two surfaces. This idea could ultimately end up making for thermoelectric exhaust pipes that help charge a vehicle’s battery, camp cooking gear that tops up phones, and clothes that use body heat to power wearable electronics.

In this case, the thermoelectric device also made use of another odd phenomenon called radiative cooling. This process is often seen in surfaces that face the sky – at night, they can become colder than the surrounding air because they radiate heat straight into space, since the atmosphere doesn’t block infrared energy. Past experiments with radiative cooling have shown promise as a way to cool buildings without needing to use energy.

Self-driving carmakers urge regulators to toss the steering wheel out the window

E322323A-8999-415C-9B4D-93BBF4BF52A6

Waymo, Cruise, and others call on the NHTSA to take action on human controls

The federal government should rewrite the safety rules for automobile manufacturing so self-driving carmakers can deploy vehicles without traditional controls like steering wheels and pedals, according to public comments submitted by top car and tech companies.

And they should be quick about it.

“We urge [the National Highway Safety Traffic Administration] to move ahead promptly to remove the regulatory barriers the agency has identified,” David Quinalty, head of federal policy and government affairs at Waymo, wrote in a letter posted online on Thursday.

How hackers invented kiteboarding

An unusual design process combining recklessness, imagination, and computers created one of the fastest-growing sports in history.

The promise of kiteboarding is that a wind strong enough to draw small whitecaps from the water can take you on a magic-carpet ride. But the same wind can be dangerously uncontrollable.Photograph from Alamy

Just as he was graduating from high school, in 1990, Chris Moore had a fanciful idea. He had noticed increasing numbers of so-called sport kites arcing through the skies above his home town of Lenexa, Kansas, outside Kansas City, Missouri. A traditional kite is tethered to its operator by a single line, and is more or less impossible to maneuver. But a sport kite—a needle-nosed, fighter-jet-like wing of nylon or polyester—has two lines, which an operator can use to induce acrobatic turns. Moore was skilled with a yo-yo and had watched riders do tricks on their bikes. He watched the sport kites soar, reverse, and double back, and wondered if the kite could become the next bicycle—a vehicle for art, competition, or some combination of the two.

Tesla offers insurance to car buyers in California, with eye toward driverless future

7BEC8D60-C938-404E-904E-9662C6D20671

SAN FRANCISCO (AP) — Tesla owners in California can now buy insurance from the electric car company in what may be the first step toward the unconventional automaker providing coverage for a fleet of driverless taxis.

The expansion announced Wednesday comes four months after Tesla CEO Elon Musk told analysts the company would branch into insuring its own cars for people who buy or lease them.

Musk believes Tesla has learned so much about its cars that it will be able to offer rates 20% to 30% below those offered by traditional insurers. That will likely to appeal to Tesla owners who have been complaining about being charged too much for coverage.

Special report: Driverless cars are the new dot-com bubble

3DECC9A3-A011-4169-97A2-0D8CF7506F77

We simply don’t know what sort of jobs will be available in the future. After all, imagine yourself in the year 1900 peering into the future. How could you know then that the proportion of people employed in agriculture in the USA would fall to a twentieth of what it was then?

Or that there would now be more people employed as mental health nurses in the NHS than there are sailors serving in the Royal Navy? Or that large numbers of people would pay good money to personal trainers to put them through their paces and ensure that they suffered the requisite amount of agony?

History is full of people who have made long-term predictions and who have been proved utterly wrong. Among economists one of my favourites is the great William Stanley Jevons, one of the most distinguished economists of the nineteenth century. In 1865 he predicted that industrial expansion would soon come to a halt due to a shortage of coal. Poor old Jevons.

So we must tread warily. Having said that, and having dosed ourselves with lashings of humility, and drunk deep from the well of scepticism, there is a lot that we can say about the future of employment in the new robot- and AI-dominated future.

One of the most widely talked about categories of jobs supposedly at risk is drivers: bus drivers, truck drivers, taxi drivers, chauffeurs, delivery drivers, and many more. A 2017 trucking industry report predicted that by 2030, out of 6.4m trucking jobs in America and Europe, about 4.4m of them could have disappeared as “robots” do the driving.

Precious metal flecks could be catalyst for better cancer therapies

33847777-C6F2-4F07-B396-B1F3BFDE3586

Tiny extracts of a precious metal used widely in industry could play a vital role in new cancer therapies.

Researchers have found a way to dispatch minute fragments of palladium — a key component in motor manufacture, electronics and the oil industry — inside cancerous cells.

Scientists have long known that the metal, used in catalytic converters to detoxify exhaust, could be used to aid cancer treatment but, until now, have been unable to deliver it to affected areas.

Facebook is challenging researchers to build a deep fakes detector

187EDA4B-77C9-4A61-AF9A-508DB1FFF6A3

Why it makes sense to fight deepfakes with deepfakes.

Deepfakes are becoming so convincing that it’s hard to tell them from real videos. And that could soon spell disaster, eroding trust in what we see online.

That’s why Facebook is teaming up with a consortium of researchers from Microsoft and several prominent research universities for a “Deepfake Detection Challenge.”

The idea is to build a data set, with the help of human user input, that’ll help neural networks detect what is and isn’t a deepfake. The end result, if all goes well, will be a system that can reliably fake videos online.

Astronauts make cement in space for the first time

BBC18B71-0775-472B-B457-F9AB73635D7C

European Space Agency astronaut Alexander Gerst works on an experiment aboard the International Space Station looking into how cement reacts in space.

Concrete could provide humans in space with better protection from radiation and extreme temperatures than many other materials.

In the future, when humans live in and visit space, they’re going to need places to stay and work. That calls for durable infrastructure such as concrete. For the first time, astronauts made cement in space as part of a project looking into the effects of microgravity, NASA said last week.
