ESRF - The European Synchrotron
The ESRF is an international research lab, where X-rays are used to unlock the secrets of matter.
A long childhood is the prelude to the evolution of a large brain
A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals, thanks to the ESRF in Grenoble, a prolonged childhood despite a small brain and an adulthood comparable to that of the great apes. This discovery suggests that an extended childhood, combined with cultural transmission in three-generation social groups, may have triggered the evolution of a large brain like that of modern humans, rather than the reverse.

Inauguration of a new CryoEM facility at the ESRF
The ESRF now hosts two state-of-the-art TITAN KRIOS cryo-electron microscopes (cryo-EM). Following the successful operation of CM01 since 2017, the ESRF welcomes CM02, a cryo-EM facility operated as a French CRG beamline by the Institut de Biologie Structurale (IBS). The official inauguration of CM02 took place on 8th November.
Learning from nature: trapping and storing carbon dioxide underground
A team led by the University of Oslo, in collaboration with the University of Maryland in USA, is investigating how to massively store carbon dioxide (CO2) underground by copying nature. Through a chemical reaction, carbon dioxide can be trapped naturally inside the Earth’s subsurface and stored as solid minerals, called carbonates. The researchers are now carrying out experiments at the ESRF with the aim to accelerate such a process.

A new extinct species of coelacanth discovered thanks to the ESRF
Scientists from the Natural History Museum (MHNG) and the University of Geneva (UNIGE) have discovered a new species of coelacanth, a fish considered to be a living fossil that only had two species known until now. This finding was possible thanks to the experiments done at the ESRF.

Scientists reveal pore formation dynamics in copper laser welding
Scientists from academia and industry have identified four ways in which pores form in copper laser welding, thanks to in-situ X-ray imaging experiments at the ESRF combined with multi-physics simulation. The results provide clues for optimisation of the manufacturing of copper components through this method.
