Today a little history was made. Verizon and Korean Telecom (KT) unveiled the world’s first live hologram international call service via the companies’ trial 5G networks established in Seoul and in New Jersey, respectively. Our cover graphic shows Verizon CEO Lowell McAdam (left) and KT CEO Hwang Chang-gyu demonstrate a hologram video call on a tablet PC at the KT headquarters in central Seoul Monday.

In the demonstration, a KT employee held a meeting with a Verizon employee in New Jersey who appeared as a hologram image on a monitor in the KT headquarters building.

It was the world’s first successful end-to-end 5G network interworking, according to the two firms. Both 5G trial networks were deployed over a 28 GHz spectrum.

Tencent, Asia’s second highest valued tech firm, has bought a five percent share in Tesla. According to a filing, the Chinese firm scooped up 8,167,for around $1.7 billion to become one of Tesla’s largest shareholders.

The news itself sent Tesla’s share price up three percent in pre-market trading. The purchase was arranged on March 17, and those now-Tencent-owned shares are worth around $2.2 billion at current market value.

Tencent is a prolific investor. It holds equity in Snap, this year’s hot tech IPO, among others following an early investment. While that interest in messaging makes sense since Tencent’s operates China’s dominant chat app — WeChat — it isn’t immediately clear whether the Tesla investment has strategic undertones. An alliance with Tencent could significantly boost Tesla’s efforts in China, which is already impressive. Chinese sales accounted for 15 percent of Tesla’s $7 billion revenue last year.

Legal frameworks, regulations and standards under the topic Defending the Core.

2017 will focus on the fundamental aspects of cyber security with a theme of Defending the Core. The 9th International Conference on Cyber Conflict will be held in Tallinn from May 30 through June 2, 2017.

CyCon is organised by the NATO Cooperative Cyber Defence Centre of Excellence. Every year, over 500 decision-makers and experts from government, military and industry from all over the world approach the conference’s key theme from legal, technology and strategy perspectives, often in an interdisciplinary manner.

Chia-Chiunn Ho was eating lunch inside Facebook headquarters, at the Full Circle Cafe, when he saw the notice on his phone: Larry Zitnick, one of the leading figures at the Facebook Artificial Intelligence Research lab, was teaching another class on deep learning.

Ho is a 34-year-old Facebook digital graphics engineer known to everyone as “Solti,” after his favorite conductor. He couldn’t see a way of signing up for the class right there in the app. So he stood up from his half-eaten lunch and sprinted across MPK 20, the Facebook building that’s longer than a football field but feels like a single room. “My desk is all the way at the other end,” he says. Sliding into his desk chair, he opened his laptop and surfed back to the page. But the class was already full.

Internet giants have vacuumed up most of the available AI talent—and they need more.

The Laser Communications Relay Demonstration (LCRD) will help NASA understand the best ways to operate laser communications systems. They could enable much higher data rates for connections between spacecraft and Earth, such as scientific data downlink and astronaut communications.

“LCRD is the next step in implementing NASA’s vision of using optical communications for both near-Earth and deep space missions,” said Steve Jurczyk, associate administrator of NASA’s Space Technology Mission Directorate, which leads the LCRD project. “This technology has the potential to revolutionize space communications, and we are excited to partner with the Human Exploration and Operations Mission Directorate’s Space Communications and Navigation program office, MIT Lincoln Labs and the U.S. Air Force on this effort.”

Laser communications, also known as optical communications, encodes data onto a beam of light, which is then transmitted between spacecraft and eventually to Earth terminals. This technology offers data rates that are 10 to 100 times better than current radio-frequency (RF) communications systems.

CAMBRIDGE, Mass. — A new propulsion engine with dime-size thrusters could be used to propel a host of spacecraft, from small satellites to crewed ships designed for interplanetary exploration.

The new propulsion engine, called Tile, could serve as an efficient and lightweight way to keep constellations of small satellites in orbit. Spaceflight companies — including OneWeb, Boeing and SpaceX — want to launch hundreds of thousands of these small satellites to provide broadband internet to everyone around the globe. And because several Tiles can be connected to produce more power, the engine has the potential to propel astronauts to Mars, according to Accion Systems, the company that designed Tile.

“Our technology starts on a nanometer scale, and then we can array that and scale that up to serve satellites,” said Natalya Bailey, CEO of Accion Systems. Bailey described the propulsion engine to an audience here at the New Space Age Conference at the Massachusetts Institute of Technology’s (MIT) Sloan School of Management on March 11.

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.

For those who missed the li-fi hype, the communications system was first invented in 2011, based on the idea of transmitting data via the imperceptible flickering of LED light — think morse code happening so fast, it’s invisible to the human eye.
