Physicists have built a new technology on a microchip by combining two Nobel Prize-winning techniques. This microchip could measure distances in materials at high precision, for example underwater or for medical imaging. Because the technology uses sound vibrations instead of light, it is useful for high-precision position measurements in opaque materials. There's no need for complex feedback loops or for tuning certain parameters to get it to operate properly. This makes it a very simple and low-power technology, that is much easier to miniaturize on a microchip. What makes it special is that it doesn't need any precision hardware and is therefore easy to produce. It only requires inserting a laser, and nothing else. The instrument could lead to new techniques to monitor the Earth's climate and human health.

New research has debunked the idea that there is an 'obesity paradox', whereby patients with heart failure who are overweight or obese are thought to be less likely to end up in hospital or die than people of normal weight. The study, which is published in the European Heart Journal, shows that if doctors measure the ratio of waist to height of their patients, rather than looking at their body mass index (BMI), the supposed survival advantage for people with a BMI of 25kg/m2 or more disappears.

Your nail bed could be trying to tell you something, including whether you've had COVID-19 or another serious infection. COVID nails are a thankfully harmless, but important indicator of your recent health.
