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.”

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.
The imaging sensors for the future Vera C. Rubin Observatory have taken their record-breaking first photos.

Thanks to Amazon’s success, CEO Jeff Bezos is the richest person in the world, worth $207 billion, according to the Bloomberg Billionaires Index.
But when he started Amazon as an online bookseller in 1994, Bezos thought it was likely that his business would fail.
The masks could screen for the coronavirus at airports, hospitals, and offices. They could also double as a diagnostic test.
Sensors produce a fluorescent light when an infected person breathes, coughs, or sneezes into the mask.
