Date Time Metamaterial Tiles Boost Sensitivity of Large Telescopes Low-cost, mass producible technology poised to help Simons Observatory yield new insights into how the universe began WASHINGTON – A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated into receivers that will be deployed at the observatory by 2022. The Simons Observatory is the center of an ambitious effort to measure the cosmic microwave background – el...

A new method for visualising the air exhaled while someone is speaking or singing could shed light on how diseases such as COVID-19 spread, and help evaluate the effectiveness of face masks.

630 New York, December 30 A new method for visualising the air exhaled while someone is speaking or singing could shed light on how diseases such as COVID-19 spread, and help evaluate the effectiveness of face masks, according to a study. The novel system, described in the journal Applied Optics, images temperature differences between exhaled breath and the surrounding air to estimate how far the breath travels before being dispersed into the surrounding air. According to study author Thomas Moore from Rollins College in the US, the new technique can also be used to study the details of how b...
