Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

Satellite sensor EPIC detects aerosols in Earth's atmosphere

Aerosols are small, solid particles that drift aloft in Earth's atmosphere. These minuscule motes may be any of a number of diverse substances, such as dust, pollution, and wildfire smoke. By absorbing or scattering sunlight, ...

Infrared imaging leaves invasive pythons nowhere to hide

For more than 25 years, Burmese pythons have been living and breeding in the Florida Everglades, where they prey on native wildlife and disrupt the region's delicate ecosystems. A new study shows that infrared cameras could ...
