A man who had his right arm amputated below the elbow has been able to feel hot and cold in his missing hand via a modified prosthetic arm with thermal sensors. After an amputation, some people can still perceive touch and pain sensations in their missing arm or leg, known as a phantom limb. Sometimes, these sensations can be triggered by nerve endings in the residual upper limb. The prosthetic works by applying heat or cold to the skin on the upper arm in specific locations that trigger a thermal sensation in the phantom hand. "In a previous study, we have shown the existence of these spots in the majority of amputee patients that we have treated," says Solaiman Shokur at the Swiss Federal Institute of Technology in Lausanne.

Modern wearables like the Apple Watch use sensors like gyros and accelerometers to detect hand movements. Those components allow them to turn on their displays when you lift your wrist, as well as to ensure you've properly washed your hand. But thanks to the work of a joint team of researchers at Cornell Unversity and the University of Wisconsin-Madison, future wearables could offer more nuanced hand detection. The team has developed a device they call the FingerTrak. The wearable employs four low-resolution thermal sensors, each the size of about a pea, to monitor the contours of the wrist.

The spread of the COVID-19 coronavirus is a fluid situation changing by the day, and even by the hour. The growing worldwide public health emergency is threatening lives, but it's also impacting businesses and disrupting travel around the world. The OECD warns that coronavirus could cut global economic growth in half, and the Federal Reserve will cut the federal interest rates following the worst week for the stock market since 2008. Just how the COVID-19 coronavirus will affect the way we live and work is unclear because it's a novel disease spreading around the world for the first time, but it appears that AI may help fight the virus and its economic impact. A World Health Organization report released last month said that AI and big data are a key part of the response to the disease in China.

What do queues, zoos, and machine learning have in common? Marwell Zoo is building better beds for their animals with IoT and machine learning. Using Watson IoT Platform, the park's keepers are working in tandem with IBM, designing a better way to reduce energy consumption. Can machine learning be used to create better conditions for animals at Marwell Zoo? The question first emerged after Andy Stanford-Clark, CTO for IBM UK & Ireland, presented an introduction to Internet of Things at a UK Chamber of Commerce conference in February 2017.
