UK nuclear fusion outfit Pulsar Fusion has fired up a chemical rocket engine running on a combination of nitrous oxide oxidiser, high-density polyethylene fuel and oxygen.

The acceptance tests of the UK-built rocket were conducted at COTEC, a UK Ministry of Defence site at Salisbury Plain in southern England.

We spoke to CEO of the company, Richard Dinan, in 2018, when he discussed the prospects for fusion power, and the use of the technology for space travel as well as electricity generation. In 2020 he was showing off an ion thruster with plasma running at several million degrees and particles fired at speeds over 20km per second.

Managers of large Chinese state-run companies have told employees to delete, shutdown and discontinue use of Tencent messaging app Weixin for work purposes, citing potential security breaches, according to the Wall Street Journal.

The news outlet named China Mobile, China Construction Bank and China National Petroleum among nine companies that confirmed the communication policy change, although none have officially gone on record.

Employees have reportedly also been warned to beware Weixin's sister app, WeChat. No details were given regarding what communication tools personnel were directed to use instead.

The torrid tale of Google's Privacy Sandbox took another turn today with the UK's Competitions and Markets Authority (CMA) saying it has "secured improved commitments" from the ad giant over the cookie crushing tech.

The CMA's claims come in the wake of yesterday's call by the UK's data watchdog, the Information Commissioner's Office (ICO), for Google and co to sort out the privacy risks posed by ads. The ICO continues to work with the CMA to review the plans of the Mountain View gang.

The investigation by the competition regulator kicked off in January amid worries that Google's intention to change its Chrome browser and phase out third party cookies in favour of a so-called Privacy Sandbox would, in fact, strengthen the megacorp's grip on the online ad ecosystem.

A company repeatedly endorsed by ministers backing the UK's Online Safety Bill was warned by its lawyers that its technology could breach the Investigatory Powers Act's ban on unlawful interception of communications, The Register can reveal.

SafeToNet, a content-scanning startup whose product is aimed at parents and uses AI to monitor messages sent to and from children's online accounts, had to change its product after being warned that a feature developed for the government-approved app would break the law.

SafeToNet was hailed this week by senior politicians as an example of "new tech in the fight against online child abuse," having previously featured in announcements from the Department for Digital, Culture, Media and Sport over the past 12 months.

The range of Thinkpads you can modernise is getting wider. XyTech is trying to crowdfund a new mainboard for the 2008 T60/T61 so fans can upgrade the much-loved noughties laptop.

"The goal is to recreate the TP experience as much as possible, while incorporating the latest CPUs and technology," XyTech's Xue Yao writes. "As the motherboard is not from [Lenovo], it will require quite a bit of hands-on from the user to get the best experience out of the machine. It will be as stable as any other computer motherboard but will not have original TP software support and features."

XyTech is not alone. CnMod is another small Chinese business that updates teenaged – and by laptop standards, that's positively geriatric – ThinkPads. The replacement motherboards come from cottage-industry scale manufacturers on the forums at 51NB.com. They offer replacement motherboards for various classic ThinkPads, including the X200, X201 and X62, updating them with modern processors, memory and storage. There's also the X330, which combines the classic keyboard of the X220 with the faster mainboard of an X230.

Something for the Weekend, Sir? I could just do with some popcorn right now.

I am loitering among the sick and deranged. The selfish fools decided to pile into the chemist's at 9am, the very moment I sensibly chose to visit. Half of them seem to be loitering around the entrance, jabbing urgently at their smartphones and muttering to themselves.

The popcorn? It will not cure my ailment but, despite research from the Rotterdam School of Management that claims otherwise, popcorn would enhance my user experience (UX) of waiting in the queue.

Episode 21 I've got nothing against conspiracy theories in general because if they didn't exist the PFY would probably have to join a book club or a sewing circle. But even the PFY will admit there's a limit, and at lunch today we think we found it ...

"So let me get this straight," I say. "The vaccine contains tiny … robots …"

"Nanobots," the bloke across the table from me chips in.

On Call Sometimes you're the one on the phone, and other times you're the one that issued the cry for help. Welcome to a story from the On Call archive where a Register reader turns the tables and claims the glory.

Today's tale comes from "Rob" and is set in the 1980s, at a City insurance company. As was common in those days, the IBM System/3 midrange computer lurked within the data centre, and this particular outfit ran its underwriting software on the system.

The System/3 that Rob was responsible for luxuriated in a spacious 64KB of RAM and featured nearly 2.5MB of mass storage via an internal disk (likely the IBM 5444, which measured 14 inches in size). Backups were as important then as they are today, and Rob's IBM was no exception. "We backed up the internal disks onto 9-track tape cartridges via an external unit," he told us, "inside which there was a plastic rack into which a number of cartridges could be loaded."
