Say "Hey Siri" when using an iPad, and Apple's virtual assistant will take over the entire display, obscuring whatever you were doing on the device. Say the same thing to your Mac, however, and Siri responds in a more multitasking-friendly way by appearing in a small window in the corner of the screen, allowing you to drag and drop retrieved items from it.

Sex is an important part of most romantic relationships – and when couples are not on the same page about their sex life, it can become a source of frustration. Research has found that couples have sex about 1 or 2 times a week, but about half of sexual advances between partners go unfulfilled. A preprint uploaded recently to PsyArXiv sheds some light on how responses to sexual advances influence individuals’ feelings of sexual and relationship satisfaction.

Sometimes, it is the very ordinariness of a scene that makes it terrifying. So it was with a clip from last week’s BBC documentary on facial recognition technology. It shows the Metropolitan police trialling a facial recognition system on an east London street. A man tries to avoid the cameras, covering his face by pulling up his fleece.

The UK has gone a week without burning any coal to make electricity - the first coal-free week since 1882. Britain has relied on burning coal for power since the Industrial Revolution, which began in the UK in the 18th Century and spread to other parts of the world. The Industrial Revolution saw new factories being built and a massive increase in the use of fossil fuels. The world's first coal-fired power station was opened in London in 1882.

Elon Musk has revealed his Neuralink startup is close to announcing the first brain-machine interface to connect humans and computers. The entrepreneur took to Twitter to tell followers the technology would be “coming soon” – though he failed to provide details.

Trees talk and share resources right under our feet, using a fungal network nicknamed the "Wood Wide Web". Some plants use the system to support their offspring, while others hijack it to sabotage their rivals.

Based on a recurring series of national surveys we conduct, we can figure out who the other candidates competing in Andrew Yang's lane are, and who the broader opponents are within the party. Yang is a more recent addition to our surveys and at this time has an insufficient sample size for which to draw conclusions.

Ever feel like your money just falls into a black hole? You might find it fitting to pick up a 50-pence coin (about 65 cents US, 95 cents Australian) honoring late British physicist Stephen Hawking.
