Science without gravity at the International Space Station

In two decades orbiting the Earth the International Space Station has become a cutting-edge cosmic laboratory, with astronauts researching everything from black holes to disease and even gardening in microgravity.

3-D-printed smart gel changes shape when exposed to light

Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3-D-printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military ...

Researchers demonstrate label-free super-resolution microscopy

Researchers have developed a new measurement and imaging approach that can resolve nanostructures smaller than the diffraction limit of light without requiring any dyes or labels. The work represents an important advance ...

Increasing efficiency in artificial photosynthesis

Chemical engineers at EPFL have developed a new approach to artificial photosynthesis, a method for harvesting solar energy that produces hydrogen as a clean fuel from water.

Moths prefer to reproduce in the dark

Night-time is no longer dark by definition in our country. 'Light pollution' is increasing by around 6% each year, while the ecological consequences are still largely unknown. 'Cloaked in darkness,' as Koert van Geffen puts ...
