New analyses of tiny fossil mammals from South Wales are shedding light on the function and diets of our earliest ancestors, a team led by researchers from the Universities of Bristol and Leicester report in the journal Nature. The team used CT scanning with synchrotron X-rays at PSI’s Swiss Light Source to reveal in unprecedented detail the internal anatomy of the mammals’ tiny jaws.

How susceptible is the global energy infrastructure to attacks by non-state actors? Has the number of attacks on this infrastructure actually increased of late? Which regions of the world are especially vulnerable? And which tactics do the attackers use? Scientists are looking to find the answers to these and other related questions with the aid of a database developed by researchers from the Center of Security Studies at ETH Zurich in collaboration with the Paul Scherrer Institute PSI.

Researchers at the PSI, the EPFL and the Chinese Academy of Science, have proven that the material SmB6 shows all the properties of a so called topological insulator – a material with electric currents flowing along its surface with all of them being polarized. Here, the property is very robust, i.e. the only current that can flow is spin polarized and is not easily destroyed by small irregularities in the structure or composition of the material. Spin polarized currents are necessary for spintronics, electronics using the electrons’ spin.

In nuclear reactors, water is dissociated at the surface of the hot fuel elements, thereby producing hydrogen. This hydrogen can penetrate the fuel cladding surrounding the actual fuel and weaken it mechanically. Researchers from the Paul Scherrer Institute (PSI) have been using neutrons and synchrotron radiation to study how the hydrogen gets into the cladding tube and what impact it can have once inside.

The molecule dicarbon (C2) is present in all flames where a carbon-containing fuel is combusted. C2 burns visibly, is behind the blue colour inside a candle flame and could also play a key role in the formation of soot. Now, for the first time, scientists from the Paul Scherrer Institute have rendered a previously invisible C2 energy state, a so-called dark state, visible. Not only is its discovery interesting for combustion researchers; it also solves a century-old puzzle in the spectrum of this omnipresent molecule.
