As drones become better and better at everything they do, it’s only natural photographers and videographers alike start pushing the boundaries of what’s possible. This particular boundary push is not for the faint of heart, however. I’m reasonably new to the drone world. While I’d been keen to dip a toe for a long time, I had been waiting for commercial applications to justify the acquisition. Thankfully, I found a window and jumped right through it.
The blockchain revolution, online gaming and virtual reality are powerful new technologies that promise to change our online experience. After summarizing advances in these hot technologies, we use the collective intelligence of our TechCast Experts to forecast the coming Internet that is likely to emerge from their application.
Here’s what learned:
Security May Arrive About 2027 We found a sharp division of opinion, with roughly half of our experts thinking there is little or no chance that the Internet would become secure — and the other half thinks there is about a 60% probability that blockchain and quantum cryptography will solve the problem at about 2027. After noting the success of Gilder’s previous forecasts, we tend to accept those who agree with Gilder.

This latest IoT security warning is hard to believe…
Warnings that our IoT devices might be spying on us are nothing new—remember the smart speaker fiasco last year? But at least we expect those devices to be listening and can exercise some caution. The latest such warning, though, takes these risks to a new level. It turns out that there may be surprising little spies hiding in our living rooms.
Last December, the FBI warned that the perilous state of IoT security means that “hackers can use an innocent device to do a virtual drive-by of your digital life.” A week earlier, that same FBI office had cautioned on the danger that smart TVs can allow “manufacturers, streaming services, and even hackers an open door into your home.”
Now a new security report from the team at Guardicore, issued today, has combined those two FBI alerts, showing just how easy it is to exploit vulnerabilities in our everyday devices. And this isn’t a data theft risk—it’s much more creepy, playing like something from a spy thriller. It’s an attack scenario that “conjures up the famous ‘van parked outside’ scene in every espionage film in recent memory,” Guardicore says.
As tiny particles traveling at the speed of light, it’s going to take a serious machine to capture photons in action, and an international team of researchers have just pieced together one that is very much up for the job. Dubbed the world’s fastest UV camera, the device is capable of capturing ultra-fast events lasting just a picosecond, quick enough to see UV photons fly through the air in real time.
The device is the handiwork of Canada’s Institut National de la Recherche Scientifique (National Institute of Research) and goes by the name of UV-CUP (compressed ultrafast photography). CUP is an emerging imaging technique that has been used to capture ultrafast events at speeds measured in trillions of frames a second, but has so far been limited to visible and near-infrared wavelengths.
“Many phenomena that occur on very short time scales also take place on a very small spatial scale,” says Jinyang Liang, who led the study. “To see them, you need to sense shorter wavelengths. Doing this in the UV or even X-ray ranges is a remarkable step toward this goal.”

A NEW LASER sensor that monitors blood glucose levels without puncturing the skin could transform the lives of millions of diabetics by providing a pain-free way of monitoring blood glucose levels.
DARPA’s near-zero-power sensors have extended battery lifetimes from four weeks to up to four years, but more work needs to be done.
