Light is all around us, and scientists are always finding new ways to study it. Recently, they've made a big step forward with tiny lenses that can do what big, bulky machines used to do. These tiny lenses, called metalens arrays, can now look at light in a way that tells us a lot about its properti
In Paterson, New Jersey, what should have been a joyous celebration turned into a health crisis.

Hospitals are super busy places where Covid-19 can easily spread. Just having general rules might not cut it. But there's a cool way to figure out what works best: agent-based modelling. This method lets researchers create a virtual hospital and see how different factors affect the spread of Covid-1
