A year after Reddit updated its policy on non-consensual intimate image (NCII) sharing—a category that includes everything from revenge porn to voyeurism and accidental nip slips—the social media platform has announced that it has gotten much better at detecting and removing this kind of content. Reddit has also launched a transparency center where users can more easily assess Reddit's ongoing efforts to make the platform safer.

According to Reddit’s 2022 Transparency Report—which tracks various “ongoing efforts to keep Reddit safe, healthy, and real”—last year Reddit removed much more NCII than it did in 2021. The latest report shows that Reddit removed 473 percent more subreddits and permanently suspended 244 percent more user accounts found to be violating community guidelines by sharing non-consensual intimate media. Previously, Reddit labeled NCII as "involuntary pornography," and the 2022 report still uses that label, reporting that the total number of posts removed was 187,258. That includes non-consensual AI-generated deepfakes, also known as “lookalike” pornography.

“It’s likely this increase is primarily reflective of our updated policies and increased effectiveness in detecting and removing non-consensual intimate media from Reddit,” the transparency report said.

Google's plans for a security system are starting to take shape. Google invested $450 million in ADT in 2020, buying a 6.6 percent stake in the security monitoring company. Two months later Google killed its in-house security system, the Nest Secure, which had a monitoring deal with ADT rival Brinks. The two companies promised to build "the next generation of smart home security solutions," and that's apparently here now as the "ADT Self Setup smart home security system."

Since the Nest Secure is dead, the brains of the system is the ADT Smart Home Hub. This is a 4.1×4.1×5.9-inch box with a keypad on top and a few other buttons for arming and disarming the security system. It's a sizable unit that's basically the size of a smart speaker, thanks to needing to fit an integrated 24-hour battery backup and a speaker grille on the front for the alarm siren, which ADT says hits 85 dB at 10 feet. Instead of a more common smart home protocol like Wi-Fi, Z-Wave, Zigbee, Google's Thread, or Matter, ADT's devices run over "DECT/ULE," an old-school wireless home security standard. I don't think that acronym means anything anymore, but officially it stands for "Digital Enhanced Cordless Telecommunications/Ultra Low Energy" (it has roots in cordless phone technology). The hub still has Z-Wave, but that's only for automation of third-party products. It also has Bluetooth for setup, and assuming this is the same hub used for ADT's old "Blue" security system, it connects to the Internet over Wi-Fi with a cellular backup.

ADT also has various security widgets you can place around the house. It's not very handy to have the control keypad on top of the hub, away from the door, so there's also a remote keypad that presumably you can wall mount next to the door and use as you come and go. ADT is also handling the door and window sensors, motion sensors, flood and temperature sensors, a car-style key fob, and surprisingly, the smoke detector. Nest famously has some extremely expensive smoke detectors, but ADT's press release calls out every compatible Google product by name, and the Nest Protect smoke detector is not listed.

We're all familiar with the elements of the periodic table, but have you ever wondered what hydrogen or zinc, for example, might sound like? W. Walker Smith, now a graduate student at Indiana University, combined his twin passions of chemistry and music to create what he calls a new audio-visual instrument to communicate the concepts of chemical spectroscopy.

Smith presented his data sonification project—which essentially transforms the visible spectra of the elements of the periodic table into sound—at a meeting of the American Chemical Society being held this week in Indianapolis, Indiana. Smith even featured audio clips of some of the elements, along with "compositions" featuring larger molecules, during a performance of his "The Sound of Molecules" show.

As an undergraduate, "I [earned] a dual degree in music composition and chemistry, so I was always looking for a way to turn my chemistry research into music," Smith said during a media briefing. "Eventually, I stumbled across the visible spectra of the elements and I was overwhelmed by how beautiful and different they all look. I thought it would be really cool to turn those visible spectra, those beautiful images, into sound."
