There were many – and all of them brilliant and passionate – women researchers at Frascati Laboratories, participating in the day of reflection on the role of women in Science.

In a paper recently published on the prestigious Physical Review Letters, the OPERA collaboration reported the appearance of ten tau neutrinos in a beam of muon neutrinos, inserting the missing tile in the puzzle of neutrino oscillation.

It all started with Fritz Zwicky, who, in the early '30s, undertook a systematic study of the Coma Cluster, a cluster of thousands of galaxies, about 20 million light-years wide, around 350 million light years away from Earth, in the direction of the constellation named Coma Berenices.

The 14th of September 2015 entered with good reason into the history of science for the first direct observation of a gravitational wave, GW150914, performed by the two LIGO interferometers in the United States.

The hunt for exotic particles composed by four quarks goes on. The latest news from the BESIII experiment at the BEPCII electron-positron collider in Beijing.

There has been a vigorous and global program of experiments and theoretical developments in the last 25 years aimed at understanding the internal spin structure of the proton.

A new elementary particle, the Axion, was predicted in the seventies by R.D. Peccei, H. Quinn, S. Weinberg , and F. Wilczek to explain why electric charges distribute homogeneously inside a neutron and don’t form an electric dipole, as happens for instance in a water molecule.

Every year, the prestigious American Physical Society (APS) issues a list of the most important articles published in the journals the APS is an editor for. For 2016, as one would expect, it was the gravitational waves discovery by the LIGO interferometer that prevailed.

During the past decades, a plethora of experimental results has firmly established that strong interaction phenomena in particle physics are correctly described by a theory known as Quantum Chromo Dynamics (QCD).
