Scientists unveil a DIY structured-illumination microscope

For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast. But the diffraction of light made it impossible to observe objects at resolutions ...

Asteroid making its closest approach to Earth this week

On 4 February, asteroid 2011 MD will make its closest approach to the Earth. Though it will not be visible with the naked eye, the asteroid will pass 15,000,000 km away from Earth—much closer than those in the asteroid ...

California supervolcano is cooling off but may still cause quakes

Since the 1980s, researchers have observed significant periods of unrest in a region of California's Eastern Sierra Nevada mountains characterized by swarms of earthquakes as well as the ground inflating and rising by almost ...

Chiro-optical force observed at the nanoscale

A research group at the Institute for Molecular Science has successfully observed the left and right handedness of material structures at the nanoscale, by illuminating chiral gold nanostructures with circularly polarized ...

Dragonfly eyes inspire new microlens array processing technique

Industry 4.0 requires simple solutions for complex functions. Optical sensors, such as pinhole cameras, can deliver a depth of focus and reasonable resolution, but they suffer from low intensity for reliable and fast imaging. ...
