Photographing people in 3D through walls using Wi-Fi

photos thru walls 3d 1

Wi-Fi can pass through walls.

This fact is easy to take for granted, yet it’s the reason we can surf the web using a wireless router located in another room. But not all of that microwave radiation makes it to (or from) our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating our homes and offices like invisible light bulbs.

Now, German scientists have found a way to exploit this property to take holograms, or 3D photographs, of objects inside a room — from outside it.

Cryptocurrency wars – Untraceable coins storming into top 10

Cryptocurrency 6c64z

Bytecoin, an untraceable privacy-preserving cryptocurrency, has just seen an astronomical triple-digit percent surge in price. The cryptocurrency soared to the all time high market capitalization of $444,000,000, before calming down to around $300,000,000 and establishing itself at the top 10 cryptocurrencies by market capitalization at the time of writing (according to CoinMarketCap). A symbolic turning point for one of the first untraceable cryptocurrencies launched in 2012.

7 laws that will have to change because of blockchain

Blockchain 6f5d

“Code is law,” as described in Lawrence Lessig’s book ‘Code and Other Laws of Cyberspace’, refers to the idea that computer code has progressively established itself as a predominant way to regulate behavior to the same degree as legal code.

With the advent of blockchain technology, code is assuming an even stronger role in regulating people’s interactions.

However, while computer code can enforce rules more efficiently than legal code, it also comes with a series of limitations.

The PowerRay drone is an aquatic spyglass for playboy fishermen

Who needs fishing prowess when you have a remote-controlled, sonar-equipped, bait-dropping, mini-submersible at your disposal? Because with the new PowerRay underwater drone, that’s exactly what you get.

The PowerRay UUV comes from Beijing-based drone manufacturer PowerVision, makers of the PowerEgg UAV that we saw last August. While the Ray officially debuted back at CES in January, a technical issue with their display (read: their tank sprung a leak) prevented the company from showing off the device in its natural environment.

The rise of the online courtroom

The digital revolution has not escaped the courts. The courtroom of tomorrow may no longer involve litigants and their lawyers pitching up armed with reams of papers to do battle before robed, bewigged judges. In fact, for many it may not involve a court at all. Judges could be replaced by computers and the courtroom with the internet to meet the needs of the 21st-century litigants.

Last month Lord Chancellor and Justice Secretary Liz Truss unveiled the Prisons and Courts Bill. Aside from wide-ranging plans to reform prisons, the Bill contained proposals to enable people and businesses with claims worth up to £25,000 to use an online digital process instead of going to court.

A real-life company is implanting microchips in employees

After a semi-painless injection between the thumb and index finger, a microchip is implanted in another employee. A cyborg is now created, and this human/machine mashup runs off to buy a smoothie using his or her new sub-dermal implant.

If that sounds futuristic, it’s because we’re conditioned to this as a sort of science fiction trope: human gets implanted, its overlords are now in control. For a Swedish company, however, the practice of implanting microchips into its employees has become routine, popular even.

A New Type of Li-Fi Has Reportedly Cracked 40 Gbps, 100 Times Faster Than the Best Wi-Fi

If you’re frustrated with slow wi-fi, you might be one of the many people eagerly awaiting the commercialisation of li-fi (or light-based wi-fi), which promises to be up to 100 times faster than the connections we use today.

Most li-fi systems rely on transmitting data via LED bulbs, which means there are some limitations to how easily the technology could be applied to systems outside the lab. But researchers have come up with a new type of li-fi that uses infrared light instead, and it’s reportedly already cracked 40 gigabits per second (gbps) in early testing.

Researchers invent the ‘perfect’ soap molecule

c

A team of researchers, led by the University of Minnesota, has invented a new soap molecule made from renewable sources that could dramatically reduce the number of chemicals in cleaning products and their impact on the environment. The soap molecules also worked better than some conventional soaps in challenging conditions such as cold water and hard water.

IBM uses tiny tubes to grow the chips of the future

i

The reign of silicon may be coming to an end. For years, researchers and entrepreneurs hoped that carbon nanotubes would revolutionize microchip design. These tiny, molecular-level structures could, in theory, be used to make chips that are six to ten times faster than today’s silicon-based variety—and use far less electricity.

Volkswagen’s upcoming, all-electric I.D., previewed in concept form a few months ago at the Paris Motor Show, is as important to the company as the original Beetle and Golf. The concept car showed off all kinds of futuristic tech that seemed like fantasy, but one of the I.D.’s coolest feature will make it to production–its heads-up display.
