New material aids in neural stimulation using light

The ability to target and stimulate neurons brings a host of benefits including better understanding brain function and treating neurological diseases. Currently, state-of-the-art microelectrode arrays (MEAs) can stimulate ...

Remote control for plants

Plants have microscopically small pores on the surface of their leaves called stomata. These help plants regulate the influx of carbon dioxide for photosynthesis. They also prevent the loss of too much water and withering ...

Tailored laser fields reveal properties of transparent crystals

The surface of a material often has properties that are very different from the properties within the material. For example, a non-conducting crystal, which actually exhibits no magnetism, can show magnetisation restricted ...

Novel chirped pulses defy 'conventional wisdom'

The 2018 Nobel Prize in Physics was shared by researchers who pioneered a technique to create ultrashort, yet extremely high-energy laser pulses at the University of Rochester.

Researchers trace path of light in photosynthesis

Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food.

New method measures super-fast, free electron laser pulses

New research shows how to measure the super-short bursts of high-frequency light emitted from free electron lasers (FELs). By using the light-induced ionization itself to create a femtosecond optical shutter, the technique ...

Experiment reveals new options for synchrotron light sources

Accelerator experts from the Helmholtz-Zentrum Berlin (HZB), the German federal metrology institute Physikalisch-Technische Bundesanstalt (PTB) and Tsinghua University in Beijing have used a laser to manipulate electron bunches ...

Ultrafast electron dynamics in space and time

Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, ...
