“In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in both experimental and theoretical nuclear physics from University of Jyväskylä, Finland, took part of international research team, which studied the nuclear charge radii of potassium isotopes. Isotopes were studied by using the collinear resonance ionization spectroscopy technique. The results indicated that the potassium isotope with a neutron number of 32 does not conform with criteria of magic neutron number. The results were published in Nature Physics journal on January 2021.”

As a joint European effort, the COSINUS experiment will be constructed 1400 meters deep below the Gran Sasso massif to trace the hidden side of the universe, dark matter. Finnish scientist will take part in the theoretical analysis of the measurements.
Italian Gran Sasso-vuoren alle 1400 metrin syvyyteen on päätetty rakentaa yhteiseurooppalainen COSINUS-koelaitteisto jäljittämään maailmankaikkeuden kätkettyä puolta, pimeää ainetta. Suomalaiset tutkijat osallistuvat kokeiden tulosten teoreettiseen analyysiin.

The researchers at the University of Helsinki (INAR) and Helsinki Institute of Physics (HIP) have studied the role of iodine oxoacids in atmospheric aerosol nucleation.

Iodine species, emitted from the sea ice and sea surface, are rapidly photolyzed to form iodine oxoacids which form new particles and may grow to become new cloud condensation nuclei.

“Researchers from Aalto University and Tampere University have observed compelling evidence on novel quantum phase of matter. This phase, known as topological superconductivity, supports exotic Majorana particles that may revolutionize future technologies. The discovery was published in Nature.”

“Aalto-yliopiston ja Tampereen yliopiston tutkijoiden yhteistyöprojektissa on saatu vakuuttavaa näyttöä uudenlaisesta aineen olomuodosta, topologisesta suprajohtavuudesta. Topologisilla suprajohteilla ja niiden sisältämillä Majorana-hiukkasilla voi olla keskeinen rooli tulevaisuuden kvanttitietokoneissa. Tutkimus julkaistiin arvovaltaisessa Nature-tiedelehdessä.”

“A Finnish research group has found strong evidence for the presence of exotic quark matter inside the cores of the largest neutron stars in existence. The conclusion was reached by combining recent results from theoretical particle and nuclear physics to measurements of gravitational waves from neutron star collisions. ”
