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.

Media Releases Particle Physics Research Using Muons Large Scale Facilities Matter and Material International team of scientists confirms surprisingly small proton radius with laser spectroscopy of exotic hydrogen. 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.

New Insights into Superconducting Materials
New Insights into Superconducting Materials
An American-Swiss research team has used a new X-ray technique at Swiss Light Source (SLS) of the Paul Scherrer Institute (PSI) to investigate the magnetic properties of atomically thin layers of a parent compound of a high-temperature superconductor. It turns out that the magnetic properties of such thin films differ by only a surprisingly small degree from those of macroscopically thick samples.

Using magnetism to understand superconductivity
EPFL research in atomic scale magnetism could play a role in the development of new materials that could permit lossless electricity transmission. Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality.

Controversy clarified: Why two insulators together can transport electricity
How can two materials which do not conduct electricity create an electrically conducting layer when they are joined together? Since this effect was discovered in 2004, researchers have developed various hypotheses to answer this question – each with its own advocates, who defend it and try to prove its validity.
