Record-breaking laser pulses
Researchers at ETH Zurich have developed a laser that produces the strongest ultra-short laser pulses to date. In the future, such high power pulses could be used for precision measurements or materials processing. The word laser usually conjures up an image of a strongly concentrated and continuous light beam.

NA62 experiment at CERN observes ultra-rare particle decay
Geneva, 25 September 2024. At a seminar held at CERN this week, the NA62 collaboration reported the unequivocal confirmation of the ultra-rare decay of a positively charged kaon into a positively charged pion and a neutrino-antineutrino pair. Experiments including NA62 have previously measured and seen evidence of this process, but this is the first time it has been measured with a statistical significance of five standard deviations , crossing the threshold traditionally required to claim a discovery in particle physics.

CMS experiment at CERN weighs in on the W boson mass
The experiment at CERN is the latest to weigh in on the mass of the W boson - an elementary particle that, along with the Z boson , mediates the weak force, which is responsible for a form of radioactivity and initiates the nuclear fusion reaction that powers the Sun. At a seminar held at CERN today, the CMS collaboration reported how it has analysed proton-proton collision data from the second run of the Large Hadron Collider , the Laboratory's flagship particle accelerator, to make its first mass measurement of this fundamental particle.

One-way street for sound waves
One-way street for sound waves
Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that person can hear us as well as we can hear them.
