Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and ...

High levels of microplastics found in Northwest Atlantic fish

A new study sheds light on the magnitude of microplastic pollution in our oceans. The study, published today in open-access journal Frontiers in Marine Science, found microplastics in the stomachs of nearly three out of every four mesopelagic fish caught in the Northwest Atlantic — one of the highest levels ...

SpaceX Will Launch the First of Its Global Internet Satellites

Last week, SpaceX realized a decade-long dream of successfully launching the most powerful rocket in the world. The Falcon Heavy’s achievement, marked resoundingly with thunderous sonic booms following twin booster touchdowns at Cape Canaveral, was only upstaged by Starman—a doomed mannequin at the wheel of Elon Musk’s Roadster With the ...
