Ice in fuel cells imaged directly for the first time
Media Releases Energy and Environment Researchers from the Paul Scherrer Institute (PSI) have succeeded in imaging the distribution of frozen and liquid water in a hydrogen fuel cell directly for the first time. They applied a new imaging technique that uses successively two beams with different neutron energies to distinguish between areas with liquid water and those with ice extremely reliably.

Media Releases Research Using Synchrotron Light World-record resolution in tomography with hard X-rays Tomography enables the interior of a vast range of objects to be depicted in 3D – from cellular structures to technical appliances. Researchers from the Paul Scherrer Institut (PSI) have now devised a method that opens up new scales of tomographic imaging and will thus make the detailed study of representative volumes of biological tissue and materials science specimens possible in future.

CERN’s ALPHA experiment measures charge of antihydrogen
Geneva, 3 June 2014. In a paper published today, the ALPHA experiment at CERN 's Antiproton Decelerator (AD) reports a measurement of the electric charge of antihydrogen atoms, finding it to be compatible with zero to eight decimal places. Although this result comes as no surprise, since hydrogen atoms are electrically neutral, it is the first time that the charge of an antiatom has been measured to high precision.

Graphene nanoribbons for
Graphene nanoribbons for "reading" DNA
One of the methods used for examining the molecules in a liquid consists in passing the fluid through a nano-sized hole so as to detect their passage. EPFL researchers have found a way to improve this technique by using a material with unique properties: graphene. If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile.

ATRAP experiment makes world’s most precise measurement of antiproton magnetic moment
Geneva, 25 March 2013. In today's Physical Review Letters , the Antihydrogen TRAP ( ATRAP ) experiment at CERN 2 's Antiproton Decelerator ( AD ) reports a new measurement of the antiprotonmagnetic moment made with an unprecedented uncertainty of 4.4 parts per million (ppm). This result is 680 times more precise than previous measurements.  The unusual increase in precision is due to the experiment's ability to trap individual protons and antiprotons, and to using a huge magnetic gradient to gain sensitivity to the tiny magnetic moment.

New results indicate that particle discovered at CERN is a Higgs boson
Geneva, 14 March 2013. At the Moriond Conference today, the ATLAS and CMS collaborations at CERN 's Large Hadron Collider (LHC) presented preliminary new results that further elucidate the particle discovered last year.  Having analysed two and a half times more data than was available for the discovery announcement in July, they find that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles.

The initial results puzzled the world three years ago: the size of the proton (to be precise, its charge radius), measured in exotic hydrogen, in which the electron orbiting the nucleus is replaced by a negatively charged muon, yielded a value significantly smaller than the one from previous investigations of regular hydrogen or electron-proton-scattering.
