Searching for an ancient syphilis DNA in newborns

The ancient bones of newborns are very useful to recover the ancient DNA of the bacteria causing syphilis, the Treponema pallidum pallidum. This is the conclusion reached by a study led by Universitat Autonoma de Barcelona ...

Solar cell polymers with multiplied electrical output

One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy into useful electricity. ...

Artificially produced cells communicate with each other

Friedrich Simmel and Aurore Dupin, researchers at the Technical University of Munich (TUM), have for the first time created artificial cell assemblies that can communicate with each other. The cells, separated by fatty membranes, ...

Flower power—photovoltaic cells replicate rose petals

With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power. Scientists of KIT (Karlsruhe Institute of Technology) reproduced the epidermal cells of rose petals that have particularly ...

Plasmonic metamaterials: From microscopes to invisibility cloaks

(PhysOrg.com) -- A new class of artificial materials called metamaterials -- which derive their properties from carefully engineered, nanostructured building blocks rather than from their chemical composition -- may one day ...

Researchers discover protein complex that controls DNA repair

The repair of damage to genetic material (DNA) in the human body is carried out by highly efficient mechanisms that have not yet been fully researched. A scientific team led by Christian Seiser from MedUni Vienna's Center ...
