Safety competence promotion in secondary education - A case of the Finnish NouHätä! Programme.

The Nouhätä! safety education programme has been organised in secondary schools in Finland for over 25 years. However, to date, it has not been systematically evaluated. The purpose of this quantitative survey is to provide information about good practices, benefits and limitations of the NouHätä! Programme; this has been done by answering the research question what variables explain pupils' safety competence after participating in a NouHätä! safety education programme? The results show that the best learning outcomes in safety education are achieved when training is organised in collaboration with teachers and safety experts.

Ashtangayoga for irritable bowel syndrome in a primary care setting: A feasibility study.

Background: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by diarrhea or constipation and other symptoms such as pain, bloating, and flatulence. The disease often has a negative effect on quality of life and is also associated with symptoms of anxiety and depression. Pharmacological treatments are not always effective, and complementary and alternative treatments are common.

Optical polarization from colliding stellar stream shocks in a tidal disruption event.

A tidal disruption event (TDE) occurs when a supermassive black hole rips apart a passing star. Part of the stellar material falls toward the black hole, forming an accretion disk that in some cases launches a relativistic jet. We performed optical polarimetry observations of a TDE, AT 2020mot.

Search for Gamma-Ray Spectral Lines from Dark Matter Annihilation up to 100 TeV toward the Galactic Center with MAGIC.

Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV.

Polarized blazar X-rays imply particle acceleration in shocks.

Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to around 1 TeV. Although the jets are known to be ultimately powered by a supermassive black hole, how the particles are accelerated to such high energies has been an unanswered question. The process must be related to the magnetic field, which can be probed by observations of the polarization of light from the jets.
