Robots get smooth moves
Life, James Hein, Published on 25/03/2026
» The subject of the week is robots. The amount of news on these keeps growing and growing. South Korea is first up here with their KAIST Humanoid. In the field test, the robot was shown running across a soccer pitch, jumping, taking shots on goal, and even doing dance moves akin to the Michael Jackson moonwalk. Many robot demonstrations still look a bit stiff but these moves were quite smooth. The robot can run at about 12kph on flat ground with the next goal at 14kph. It can climb a ladder with 40cm steps and the knees can generate 320 Newton metres of peak torque so it can push heavier objects. The current model is based on the lower human half but the goal is for a full humanoid form that can work with people in industrial environments.
Sabine has the science you're after

» Sabine Hossenfelder is one of the people I regularly watch on the YouTube platform. She is a physicist but also veers into other areas such as artificial intelligence and quantum computing. For her latest video -- In Which I Lose Faith In Quantum Computing -- she makes a number of interesting observations. In short, apart from some very specific applications, quantum computing, even if it is scalable from current technology, has limited application. It also has the potential of bringing down a number of current companies highly focused on this technology, or at least some of their divisions. Artificial intelligence takes up a lot of the space that quantum computing could do well in, but for the present at least, AI does it better. The next 10 years, or less, will be important to see how both of these directions develop, or not. If you are interested at all in physics, maths and occasionally quantum computing, then Sabine Hossenfelder provides some interesting perspectives.
Moving images to the next level

» Let's start this week with a couple of software and technology announcements. The first is from the developer Dominic Szablewski. He has developed a simple, new image format. You will have heard of PNG, JPEG, MPEG, MOV and MP4, which he calls complex. Enter the Quite OK Image Format (QOI). Most of the older formats are closed, need libraries and a lot of computing power to implement and use.
Finally, an iPod replacement

» Those who have known me for a while know I'm a lover of new technology. Aside from computer- and guitar-related items, I also like to listen to good quality sound playback. To further that goal I recently picked up a few FiiO devices. The M5 is a small, square, HD music player. It supports all Bluetooth protocols and when they are available up to a 2TB microSD card. While the unit will play back MP3s the focus is on the high-end codecs including FLAC. I paired this with the new FH7 in-ear headphones, which provided the broadest soundscape I have ever listened to and allowed me to follow a single instrument through the entire song. The last item was their BD3, a small unit that plugs into a cable allowing the headphones to act as a Bluetooth unit that can be paired to the M5 if I decide to wear it like a watch. As I found out when researching, you can pay some very large sums for headphones and related equipment but this set seems to be a nice sweet spot of quality and flexibility without going crazy.
None more black

» Accidental discoveries have been responsible for many useful items like rubber and penicillin. A couple of science types at MIT in the US wanted to see if they could grow carbon nanotubes on aluminium to increase its conductance properties. Instead they found they had made the blackest substance yet known to man. It absorbs 99.96% of the light from any angle making it 10 times blacker than the current options. Potential uses include telescopes, optical blinders and art. Carbon nanotubes, is there anything they can't do, eventually?
Privacy an artefact of times past

» If you have learned nothing else from my many years of writing, it should be that unless extraordinary steps are taken, personal data privacy doesn't exist, except perhaps in the deluded minds of government officials. The only thing privacy laws do these days is stop you from returning someone's lost phone. In just one day in the news, I read reports about Huawei infiltrating Facebook, another Spectre CPU problem, political data harvesting in the UK, insecure military servers in the UK, Chinese hackers interested in Cambodia (and the rest of the world) along with other items about lost or hacked data. Yahoo and Google collect far more than the whole of the US spy agencies combined, though at least the latter doesn't deliberately spread it around or sell it to marketers.
