Via Science Alert:

At the moment when we talk with satellites, we use polarised light, which can only vibrate on a single plane, because it's not affected by turbulence in the air. But this is extremely slow, as only one bit of information can be carried by each particle of light.

In order to speed this up, physicists have been looking for a way to encode more information into photons - and in the '90s they began investigating twisting light, which can be sent like a corkscrew across long distances. This is known as orbital angular momentum, or OAM, and it opens up the potential for ridiculously fast and secure communication.

This still image was taken from a new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, showing the wide range of wavelengths – invisible to the naked eye – that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.

Scientists from Japan have harvested solar energy using an exceptionally large number of light absorbers to relay photons via antennas into one final energy acceptor. This two-step sequence closely mimics natural photosynthesis, resulting in greater and more efficient energy transfer.

In 2005, Stanford scientist Karl Deisseroth discovered how to switch individual brain cells on and off by using light in a technique he dubbed 'optogenetics'.

Research teams around the world have since used this technique to study brain cells, heart cells, stem cells and others regulated by electrical signals.

However, light-sensitive proteins were efficient at switching cells on but proved less effective at turning them off.

Now, after almost a decade of research, scientists have been able to shut down the neurons as well as activate them.

Scientists in Germany have succeeded in stopping light - the fastest thing in the universe - for a whole minute, smashing earlier records. Researchers at Darmstadt Technical University achieved the remarkable feat by trapping it in a crystal.
