Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have ...

U.S. Fish and Wildlife Service via Flickr under CC BY 2.0 Butterfly populations in the United States have dropped by almost a quarter in the last two decades, according to a new analysis published ...

Two-thirds of studied species declined by more than 10%, the study said. Butterfly populations have dropped by 22% across 554 recorded species in the United States, according to a new study in the ...

The findings revealed that 33% of butterfly species have experienced significant population declines over the past two decades, with 107 out of the 342 species examined losing more than half of ...

US butterfly populations have declined by 22% since 2000, with 114 species showing significant drops. A study published in Science found insecticides, climate change, and habitat loss are driving ...

We found declines in just about every region of the continental U.S. and across almost all butterfly species. Overall, nearly one-third of the 342 butterfly species we were able to study declined ...

A small international team of nanotechnologists, engineers and physicists has developed a way to force laser light into becoming a supersolid. Their paper is published in the journal Nature.

Still, researchers didn’t have enough data to include some of the most imperiled butterfly species, which probably experienced some of the steepest declines. And the data was quite likely biased ...
