The world has been abuzz for weeks now about the inclusion of a journalist in a group message of senior White House officials discussing plans for a military strike. In that case, the breach was the result of then-National Security Advisor Mike Waltz accidentally adding The Atlantic Editor-in-Chief Jeffrey Goldberg to the group chat and no one else in the chat noticing. But what if someone controlling or hacking a messenger platform could do the same thing?

When it comes to WhatsApp—the Meta-owned messenger that’s frequently touted for offering end-to-end encryption—it turns out you can.

A clean bill of health except for ...

A team of researchers made the finding in a recently released formal analysis of WhatsApp group messaging. They reverse-engineered the app, described the formal cryptographic protocols, and provided theorems establishing the security guarantees that WhatsApp provides. Overall, they gave the messenger a clean bill of health, finding that it works securely and as described by WhatsApp.

Over the last century or more, humanity has been developing an ever-growing list of chemicals that have never been seen by Earth's creatures. Many of these chemicals end up being toxic contaminants that we'd love to get rid of, but we struggle to purify them from the environment or break them down once we do. And microbes haven't had much chance to evolve the ability to break them down for us.

Over the last few years, however, we've found a growing number of cases where bacteria have evolved the ability to break down industrial contaminants and plastics. Unfortunately, these bacteria are all different species, target different individual contaminants, and thrive in different environments. But now, researchers have developed a new way to take the genes from all these species and place them in a single bacterial strain that can decontaminate complex waste mixtures.

Targeting contaminants

The inspiration for this work was the fact that a lot of industrial contamination contains a mixture of toxic organic molecules, but is found in brackish or salty water. So, the research team, based in Shenzhen, China, started by simply testing a number of lab strains to determine the ability to survive these conditions. The one that seemed to do the best is called Vibrio natriegens . These bacteria were discovered in a salt marsh, and their primary claim to fame is an impressive growth rate, with a population being able to double about every 10 minutes.

There is no product category that better embodies the XKCD take on standards than smart home. With an ocean of connectivity options and incompatible standards, taming this mess has been challenging, but Matter could finally have a shot at making things a little less frustrating. The latest version of the standard has launched, offering multiple ways to streamline the usually aggravating setup process.

The first public release of Matter was in late 2022, but compatible systems didn't get support until the following year. Now, there are Matter-certified devices like smart bulbs and sensors that will talk to Apple, Google, Amazon, and other smart home platforms. Matter 1.4.1 includes support for multi-device QR codes, NFC connection, and integrated terms and conditions—all of these have the potential to eliminate some very real smart home headaches.

It's common for retailers to offer multi-packs of devices like light bulbs or smart plugs. That can save you some money, but setting up all those devices is tedious. With Matter 1.4.1, it might be much easier thanks to multi-device QR codes. Manufacturers can now include a QR code in the package that will pair all the included devices with your smart home system when scanned.
