When ESA's Juventas CubeSat lands on Dimorphos in 2026 to assess the aftermath of last year's spectacular collisions with NASA's DART spacecraft, its GRAvimeter for small Solar System bodies (GRASS) instrument will directly measure the asteroid's gravitational pull, which is a millionth that of the Earth.In September 2022, NASA's Double Asteroid Redirection Test (DART) rammed into Dimorphos, which orbits around the larger asteroid Didymos, as part of an experiment to learn more about how to deflect potentially dangerous…

The Hopi HP-9800 power meter. Adrian Kingsley-Hughes/ZDNETAs part of my work, I test a lot of devices that are mains-powered (or wall-powered), and one of the tests I carry out is power consumption. I've had a lot of questions about the devices I use for this task, so here I'll outline the tools I use, why I use then, why you probably shouldn't use them, and what you should use instead.There are a lot of different tools you can buy for measuing power consumption, ranging from very cheap to very expensive. Also: The…

Using a brain implant that can record neural signals over many months, my research team and I have discovered objective biomarkers of chronic pain severity in four patients with chronic pain as they went about their daily lives.Pain is one of the most important and basic subjective experiences a person can have. While there is plenty of evidence that perception of pain takes place in the brain, there is also a major knowledge gap regarding where and how pain signals are processed in the brain.Even though pain is…

The Importance of Thermometers During the Pandemic As the pandemic continues, one of the essential things people missed having at home is a thermometer. Thermometers are critical for detecting fever, which may indicate COVID-19 infection. Many people had to go to the pharmacy to purchase one because of this, despite modern mobile technology. Hence, Google has decided that its next mobile device, the Google Pixel 8 Pro, will feature a thermometer function, making it even more useful. New Features of Google…

In our previous blog, MachineX: Layman's Guide to Association Rule Learning, we discussed what Association rule learning is all about, and as you can already tell, with a large dataset, which almost every market has, finding association rules isn't very easy. For these purposes, we introduced measures of interestingness, which were support, confidence, and lift. Support tells us how frequent an itemset is in a given dataset and confidence tells us about the reliability of that rule. Due to large datasets, it is…

The snow blanketing the Sierra lies so deep that the mountain range looks surprisingly swollen and "puffy,"…

MIT researchers have made an open-source version of the “City Scanner” mobile pollution detector that lets people check air quality anywhere, cheaply. Pictured are some examples of the latest version of the device, called Flatburn, as well as a researcher attaching a prototype to a car.

Post-rock titans Mogwai have signed several very good albums to their Rock Action label recently: Kathryn Joseph’s superlative for you who are the wronged, the magnificently glum Arab Strap comeback As Days Get Dark, and Strap spin-off Lichen Slow’s debut, Rest Lurks. Now we can luxuriate in Cloth’s latest collection of gentle guitar pop, thanks to Glasgow twins Rachael and Paul Swinton. They began spinning Cloth into gold at college seven years ago, releasing one album and an EP since. “Just keep it simple,” murmurs…

Google Maps is easily one of the must-have mobile apps that you need to install when setting up a new phone, whether it’s iPhone or Android. It’ll help do more for you than help navigate your surroundings to reach your destination, although you’ll use Google Maps for directions the most. But Google Maps has other neat features, like the ability to measure the distance between any two places. The feature is built into both the desktop and mobile versions of the app, and you can use it easily if you’re…
