Final images from Cassini spacecraft

Researchers are busy analysing some of the final data sent back from the Cassini spacecraft which has been in orbit around Saturn for more than 13 years until the end of its mission in September 2017.

Molecular probe maps misfolded proteome state in live cells

The folding state of the proteins in live cells often reflect the cell's general health. Australian scientists have developed a molecular probe that senses the state of the proteome—the entire set of the proteins—by measuring ...

Of ants and men: Ant behavior might mirror political polarization

Could the division of labor in an anthill be driven by the same social dynamics governing the gap between liberals and conservatives? That was the surprising question tackled by Princeton biologists Chris Tokita and Corina ...

A climate change double whammy in the US Corn Belt

The United States Corn Belt includes western Indiana, Illinois, Iowa, Missouri, eastern Nebraska, and eastern Kansas. The region has dominated corn production in the U.S. since the 1850s, accounting for more than a third ...

Change of shifts at the north pole

After exchanging research teams and crewmembers, the greatest expedition to the Central Arctic of all time is now entering the next phase, during which urgently needed research into the Arctic climate system will be conducted. ...

Why are giant pandas born so tiny?

Born pink, blind, and helpless, giant pandas typically weigh about 100 grams at birth—the equivalent of a stick of butter. Their mothers are 900 times more massive than that.

Polarizer

A polarizer is an optical filter that passes light of a specific polarization and blocks waves of other polarizations. It can convert a beam of light of undefined or mixed polarization into a beam with well-defined polarization. The common types of polarizers are linear polarizers and circular polarizers. Polarizers are used in many optical techniques and instruments, and polarizing filters find applications in photography and liquid crystal display technology. Polarizers can also be made for other types of electromagnetic waves besides light, such as radio waves, microwaves, and X-rays.
