German semiconductor maker Infineon Technologies AG announced that it’s producing a printed circuit board (PCB) that dissolves in water. Sourced from UK startup Jiva Materials, the plant-based Soluboard could provide a new avenue for the tech industry to reduce e-waste as companies scramble to meet climate goals by 2030.

Jiva’s biodegradable PCB is made from natural fibers and a halogen-free polymer with a much lower carbon footprint than traditional boards made with fiberglass composites. A 2022 study by the University of Washington College of Engineering and Microsoft Research saw the team create an Earth-friendly mouse using a Soluboard PCB as its core. The researchers found that the Soluboard dissolved in hot water in under six minutes. However, it can take several hours to break down at room temperature.

In addition to dissolving the PCB fibers, the process makes it easier to retrieve the valuable metals attached to it. “After [it dissolves], we’re left with the chips and circuit traces which we can filter out,” said UW assistant professor Vikram Iyer, who worked on the mouse project.

The video below shows the Soluboard dissolving in a frying pan with boiling water:

“Adopting a water-based recycling process could lead to higher yields in the recovery of valuable metals,” said Jonathan Swanston, CEO and co-founder of Jiva Materials. Jiva says the board has a 60 percent smaller carbon footprint than traditional PCBs — specifically, it can save 10.5 kg of carbon and 620 g of plastic per square meter of PCB.

Infineon has produced three different circuit board prototypes using the Soluboard framework. The company is currently only using the dissolvable PCB for demo and evaluation boards, and it says around 500 units are now in use. However, it’s “exploring the possibility of using the material for all boards” with an eye on expanding adoption over the next few years. Based on the results of stress tests, it also plans to “provide guidance on the reuse and recycling of power semiconductors removed from Soluboards” to lessen the chances of the salvageable parts from future production models going to waste.

Mazda’s MX-30 is a strange EV, and it appears the company knows this. The automaker is pulling the small crossover from the US market after the 2023 model year. The company says it’s currently focused on “large platform” plug-in hybrids like the CX-70 and CX-90, and also offers conventional hybrids like the CX-50.

The MX-30 is Mazda’s first and only mass-produced EV to date, and it came to the country in fall 2021 as a California-only model. From the start, its prospects were limited by a number of unusual business decisions. On top of its small size, it had just a 35.5kWh battery with an estimated 100-mile range. This was supposed to make it feel more like a gas car and limit the car’s CO2 footprint, but the net result was a car that was both less exciting to drive and less practical than competing EVs costing significantly less than Mazda’s $35,385 sticker. The outgoing current-gen Chevy Bolt costs $9,000 less while delivering more performance and over twice the range.

Sales were accordingly poor. Mazda has sold just 571 MX-30 units in the US over three years. In some countries, the company has reworked the machine as a plug-in hybrid with a rotary gas engine and an estimated 53 miles of electric-only driving.

Mazda is rethinking its EV strategy. It plans to introduce cars based on both an existing platform as well as a new framework. There are claims the company might use a future Toyota platform expected to deliver over 600 miles on a charge. The MX-30 discontinuation isn’t the end, in other words — rather, it’s an acknowledgment that the company needs to be more competitive.

The move is also a reflection of Japanese brands’ general trouble entering the EV market. Honda might not replace its E compact car, and is refocusing on SUVs like next year’s Prologue as well as its collaboration with Sony. Toyota and Subaru, meanwhile, had problems launching the bZ4x SUV crossover and its Solterra equivalent. For now, they largely have to rely on hybrids to attract buyers.

A New York Times investigation uncovered earlier this year that the US government used spyware made by Israeli hacking firm NSO. Now, after an FBI investigation into who was using the tech, the department uncovered a confusing answer: itself, according to the New York Times on Monday. 

Since 2021, the Biden administration has taken steps toward parting ways with NSO, given the firm’s reputation for shady tools like Pegasus that lets governments discreetly download personal information from hacked phones without the user’s knowledge. But even after the president signed an executive order banning commercial spyware in March, an FBI contractor used NSO’s geolocation product Landmark to track the locations of targets in Mexico. 

The FBI had inked a deal with telecommunications firm Riva Networks to track drug smugglers in Mexico, according to TheTimes. The spyware let US officials track mobile phones because of existing security gaps in the country’s cellphone networks. While the FBI says it was misled by Riva Networks into using the tech, and has since terminated the contract, people with direct knowledge of the situation said the FBI used the spyware as recently this year. 

This isn’t the FBI’s first run in with NSO and its spyware tools. Prior to the executive order banning the products for government use, the agency considered using Pegasus to aid in its criminal investigations. Spyware generally gained a bad reputation for its use to surveil citizens and suppress political dissent, with NSO considered one of the largest in the business.

The devs behind AI-based sample editing software Samplab are back with a free VST3 plugin that generates samples from text prompts. The appropriately-named TextToSample is a plugin that opens inside your DAW or as a standalone tool, allowing you to type, say, “bubbly synth melody” to create a, well, bubbly synth melody to do with as you see fit.

TextToSample utilizes Meta’s open-source AI-based sound generation toolset, MusicGen, and was trained using data provided by the algorithm. You can also drag and drop pre-existing sounds into the plugin and have it generate related samples, in addition to typing out commands.

The UI is extremely minimal and sparse, which makes it easy to use, but does present some inherent limitations. For instance, it doesn’t take pre-existing music on your track into account, so your first, second, and even third attempts will likely not match the tone you are going for. It also has trouble recognizing basic music concepts like keys, scales and BPM. Just like most AI-creation platforms, you aren’t going to get a perfect match right away. You’ll have to tweak, augment and provide further instructions, bit by bit, until satisfied.

However, when you get there, it’s pretty darn fun, creating the kinds of happy accidents you’d never stumble into on your own. Check out the demo video and that little flourish of guitar at the tail end of the sample as an example.

This is an AI tool in the year 2023, so there are some bugs. During experiments, we ran into issues like the plugin adding drums when we clearly stated that we didn’t want percussion. To that end, Samplab says the tool is not intended to “replace human musicians, which it’s not capable of doing anyway.” It’s free, though, so there’s no harm in checking it out, and the technology should improve as more people use it.
