CAPE CANAVERAL, Fla. — Blue Origin’s New Glenn rocket has been selected by Canadian-based Telesat to send a fleet of satellites into orbit. The payload for these flights could help improve web services around the globe.

The satellites, designed to provide internet services across the globe, will be sent to low-Earth orbit by Texas-based Blue Origin’s New Glenn over the course of multiple launches.

‘Quiet’ light

Posted by in categories: computing, internet, quantum physics

Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser’s capacity to do so is measured in terms of its linewidth, or coherence, which is the ability to emit a constant frequency over a certain period of time before that frequency changes.

In practice, researchers go to great lengths to build highly coherent, near-single-frequency lasers for high-end systems such as atomic clocks. Today, however, because these lasers are large and occupy racks full of equipment, they are relegated to applications based on bench tops in the laboratory.

There is a push to move the performance of high-end lasers onto photonic micro-chips, dramatically reducing cost and size while making the technology available to a wide range of applications including spectroscopy, navigation, quantum computation and . Achieving such performance at the chip scale would also go a long way to address the challenge posed by the internet’s exploding data-capacity requirements and the resulting increase in worldwide energy consumption of data centers and their fiber-optic interconnects.

Israeli cyberexpert detects China hack in Ottawa, warns against using Huawei 5G

Posted by in categories: business, cybercrime/malcode, engineering, government, internet

OTTAWA — A Chinese telecommunication company secretly diverted Canadian internet traffic to China, particularly from Rogers subscribers in the Ottawa area, says an Israeli cybersecurity specialist.

The 2016 incident involved the surreptitious rerouting of the internet data of Rogers customers in and around Canada’s capital by China Telecom, a state-owned internet service provider that has two legally operating “points of presence” on Canadian soil, said Yuval Shavitt, an electrical-engineering expert at Tel Aviv University.

Shavitt told The Canadian Press that the China Telecom example should serve as a caution to the Canadian government not to do business with another Chinese telecommunications giant: Huawei Technologies, which is vying to build Canada’s next-generation 5G wireless communications networks.

For Industrial Robots, Hacking Risks Are On the Rise

Posted by in categories: biotech/medical, cybercrime/malcode, employment, engineering, internet, robotics/AI

In the future, industrial robots may create jobs, boost productivity and spur higher wages. But one thing seems more certain for now: They’re vulnerable to hackers.

Factories, hospitals and other big robot users often lack sufficient levels of defense against a digital attack, according to cybersecurity experts, robot manufacturers and engineering researchers. The risk levels are rising as more robots morph from being offline and isolated to being internet-connected machines, often working alongside humans.


5G promises to make factories a lot smarter. And that means they’ll be a lot more vulnerable.
