Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

How do photosynthetic organisms harvest light so efficiently? To help answer this question, researchers have developed an ultrafast transient absorption microscope with sensitivity approaching the ...

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, however, too much light is often harmful to the sample—for example, when imaging ...

Light is a pivotal environmental signal that controls biological processes by regulating gene transcript abundances. This study unravels a regulatory mechanism whereby light signals regulate ...

The motion of whizzing electrons has been captured like never before. Researchers have developed a laser-based microscope that snaps images at attosecond — or a billionth of a billionth of a second — ...

A team of researchers has developed the first transmission electron microscope which operates at the temporal resolution of a single attosecond, allowing for the first still-image of an electron in ...
