Here’s another neat thing drones can do—beam power across the sky to recharge sensors in hard-to-reach places.

Remote sensors play a valuable role in collecting data—but recharging these devices while they are scattered over vast and isolated areas can be tedious. A new system is designed to make the charging process easier by using unmanned aerial vehicles (UAVs) to deliver power using radio waves during a flyby. A specialized antenna on the sensor harvests the signals and converts them into electricity. The design is described in a study published 23 March in IEEE Sensors Letters.

New numbers from the digital asset management giant Grayscale show investors are collectively throwing big money into Ethereum for the first time, on top of record investment numbers for Bitcoin.

According to Grayscale’s Q1 2020 report, institutions are taking a serious interest in ETH, enough to print a record quarterly inflow into the Grayscale Ethereum Trust.

Spencer Noon, the head of crypto investments at DTC Capital, says the numbers show Ethereum has reached a turning point with high-net worth investors.

In this video, we’ll be discussing 5G – more specifically, what it is and its ability to change our world! 5G is a core technology in establishing the digital infrastructure of the future and will be essential in how all of the over 50 billion mobile and connected devices by 2020 will communicate together!

[0:25–2:55] First we’ll take a quick look at the history of mobile networks, and how they have evolved over the years to present day.

More and more, people don’t care about expert views. That’s according to Tom Nichols, author of “The Death of Expertise,” who says Americans have become insufferable know-it-alls, locked in constant conflict and debate with others over topics they actually know almost nothing about. Nichols shares his humble opinion on how we got here.

The airspace above future battlefields is expected to be increasingly congested with large numbers of unmanned aerial systems, manned aircraft, munitions and missiles filling the skies. To de-conflict airspace activities of friendly forces and rapidly counter an enemy’s actions on the battlefield requires new technologies to effectively integrate effects from all domains.

Part of the problem is too few novel antibiotic candidates, according to Pew.

Algae biofuel certainly faces an uphill battle these days, what with the global oil price crash and competition from electric vehicles. Nevertheless, there may be a glimmer of hope for algae biofuel fans, in the form of an ultra-fast 3D printer housed in a California laboratory. In an interesting sustainability twofer, the same machine might also spit out an assist for the world’s ailing coral reefs.
