The international Borexino Collaboration has announced the first observation of neutrinos from the CNO process in the Sun, which experimentally confirms the second mechanism for energy generation in stars. Earlier, only neutrinos from the proton–proton cycle were observed. This discovery is highly important for astrophysics since in stars more massive than the Sun energy is mainly produced through the CNO cycle. The results of the investigation are published in Nature.

The SC230 superconducting cyclotron was designed for the JINR medical research programme implementation. The accelerator is able to provide an intense beam for a new and promising flash therapy method.
The SC230 is an isochronous four-sector compact cyclotron with a 1.7-T magnetic field in the center. Superconducting coils will be enclosed in a cryostat, all other parts of the cyclotron are “warm”. Acceleration is performed at the fourth harmonic mode of the accelerating radio-frequency (RF) system consisting of four resonators located in cyclotron valleys. The accelerator will use an internal Penning-type source with a hot cathode, and the low magnetic field makes it possible to use the external axial beam injection. The results of computer simulation of cyclotron systems are presented.

The wide audience should know about scientific research. The audience needs it, and in the long run, scientists need it too. However, communicating science, one should act properly and not only have expertise in the subject field but also consider the target audience. There are plenty of formats and platforms for communicating science; however, they are not always efficient. Recently, the book “Explaining Science: Guide for Popular Science Writers” has been issued by Alpina Publisher. Igor Ivanov, a DLNP employee, shares his 20-year experience in writing popular science commentaries, analyzes typical errors, and describes his methods of writing a good popular science text. Inspired by this book, DLNP initiates an online talk on high-quality science popularization. We will discuss not only popular science literature but also other formats of scientific communications, particularly, their application to science advanced at JINR.

At DLNP, the adjustment and commissioning work is well under way at LINAC-200, the first stage of the electron linear accelerator LINAC-800. The accelerator is intended for carrying out methodological investigations of detectors developed at JINR, solving applied problems with the use of electron beams, and implementing educational programmes of the JINR University Centre. The accelerator will produce electron beams with energies of 10 MeV to 200 MeV in a wide intensity range.

Photodetectors with internal amplification such as vacuum photomultiplier tubes (PMTs), silicone photomultipliers (SiPMs) and avalanche photodiodes (APDs) play a significant role in advancement of science and technology. They are used in up-to-date medical equipment—positron emission tomographs (PETs) and gamma chambers; in cargo and luggage control systems—scanners and introscopes; in laser location and lidars, and in many other areas.

In modern experimental nuclear physics, photodetectors of this kind are used in scintillation counters, time-of-flight systems, scintillation homogeneous and heterogeneous calorimeters, Cherenkov detectors, trackers, large-scale liquid scintillator detectors and water Cherenkov detectors employed for neutrino physics and other purposes.
