Photosynthetic organisms need to cope with a wide range of light intensities, which can change over timescales of seconds to minutes. Too much light can damage the photosynthetic machinery and cause ...

The collection of sunlight for food/fuel can be hazardous for plants (and algae). Plants use powerful photo-protective defense mechanisms to meet the challenges of different environments. Aa Aa Aa ...

Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal ...

CELL WORSHIPPERS: Design Bridge senior designer Gali Lucas and Berlin-based sculptor Karoline Hinz collaborated on Absorbed by Light, an installation that comments on “how we’re constantly drawn to ...

The first hydrogen to form absorbed light from the first stars in the universe. Eventually, the universe filled up with stars and galaxies that reionized this hydrogen, allowing photons to travel ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

A new material capable of oscillating using absorbed light energy has been developed by engineers studying enhanced structures called metamaterials. The optically-driven mechanical oscillator, as ...

A research team has developed a new way to measure and predict how plant leaves scatter and reflect light, revealing that ...

Physicists in Spain and the UK have calculated that graphene – a layer of carbon just one atom thick – could be used to create a perfect absorber of light if it is doped and patterned into a periodic ...
