This illustration shows a chlorosome on the bacterium, which makes it possible for the bacterium to live in extreme places where it has found its niche. Here you can see how the light energy is trapped and transferred to the organism. (1.) is the chlorosome itself, which holds up to 200,000 light-harvesting molecules – known as bacteriochlorophyll molecules – which capture photons from the Sun. The molecules transfer the photon’s energy down to the baseplate, which is the structure identified by the Danish-led group (2). The nanotubes are located in the baseplate, and they form the basis for the light-harvesting molecules, as well as efficiently transferring energy towards the rest of the reaction centre in the bacterium (shown here in grey), where photosynthesis can take place. Visible in the enlargement (a) is the way the red strands – consisting of proteins – encapsulate the actual light-harvesting molecule that transfers the energy. In a way, this is reminiscent of a wire, where the protein is the insulation and the molecule is the copper inside – this ‘wire’ is more clearly visible in (b). The baseplate’s nanotubes are shown here lined up in a row in the baseplate. (Illustration: Jakob Toudahl Nielsen)

Something new has been found under the Sun!

Bacterial photosynthesis is brilliant at the same time as being treacherously difficult to understand. By combining ultra-modern technology with an unusual series of methods, an international team of researchers has succeeded in finding the last piece in an important puzzle – thereby achieving a breakthrough in the work to understand how one of…

Generation of complex gene architectures in the human genome

Intense investigations during the past 10-15 years have revealed that the human genome is transcribed in a manner that is much more complicated than previously appreciated. A collaboration between researchers from Aarhus and Copenhagen now reveals some underlying principles leading to such promiscuous genome activity.

Greenland sharks live for hundreds of years

While the more than 5-metre-long Greenland shark is one of the world’s largest sharks, it is also one of the least understood animals on our planet. The Greenland shark’s general biology and way of life have been a mystery to biologists for many years. However, marine biologists at the University of Copenhagen have now deployed an epoch-making…
