With a screen that shows a cutesy little avatar, it has drawn comparisons with Tamagotchis. “We’ve packed a lot of technology into this little guy,” the Meta founder told the San Francisco audience.

artificial intelligence wrong: is algorithm really fair

Imagine two men. Both are the same illness, the same symptoms. The system of a hospital gives each patient a risk score, and according to that score, one will get additional care, and none will. The system marked a high risk patient, recommended extra care. The disease is the same, but the result is different. What's the difference? The answer is a surprise.

Weatherwatch: How UK firm’s low-cost tech can warn of volcanic eruptions

VolcanoTech’s sulphur dioxide detecting sensors are in already in use in a number of countries Weather forecasts now include air quality warnings and cities have networks of air quality sensors driving real-time maps online. Similar air quality sensors can warn of an imminent volcanic eruption. Just as a fizzy drink releases carbon dioxide when the pressure is released, rising magma emits dissolved sulphur dioxide as it rises. So a big increase in this gas warns that a volcanic eruption may be imminent. Continue reading...

Low-e windows keep homes cool … but may set neighbours’ property on fire

Low-emissivity windows also keep houses warm in winter, but use on bowed glass can have magnifying-glass effect Low-emissivity or low-E window glass is a useful green technology for keeping buildings warm in winter and cool in summer … but a rare side-effect can set the neighbours’ property on fire. The glass is coated with a thin layer of metal or metal oxide which lets visible light through but acts like a mirror in the infrared. Heat from the interior is reflected back in, retaining warmth in winter, while unwanted solar radiation is repelled in summer. Continue reading...

Drones offer alternative to balloons for weather research

Pre-programmed flights gather data at different altitudes then return to bases to recharge and download Weather happens in the boundary layer, the atmosphere from ground level to a few thousand metres, but this can be difficult to study in detail: weather stations are too low, and aircraft are expensive. Instrumented weather balloons are the traditional solution, and thousands are released every day. But these are at the mercy of the wind and use irreplaceable helium. Drones offer an alternative and the US company Meteomatics has taken the idea further with Meteobase, a base station on the gro
