. Two international teams of physicists, including RIKEN researchers, have trapped and manipulated  atoms made out of antimatter, in milestone experiments that should help to reveal why the substance is so rare in our Universe. . Since its existence was first predicted by physicist Paul Dirac in 1931, antimatter has become an increasingly common sight. …

. . Most of our Universe consists of hydrogen atoms, which are often found under extraordinarily high pressure as high as tens of millions of times the atmospheric pressure of Earth. Understanding the exotic physics of such a high-pressure regime will contribute to our understanding of planet formation, hydrogen storage, room temperature superconductivity and other …

. The matter that makes up the universe consists of particles such as electrons and protons, as well as their counterparts known as antiparticles. Particles and antiparticles that collide, however, annihilate each other in an intense flash of energy. Nevertheless, the Italian physicist Ettore Majorana proposed that some particles could exist that are their own …

. העיסוק במיתוסים הדתיים על בריאת העולם, ובדרך שבה הם מתאימים, או לא מתאימים לתיאוריות מדעיות שונות, ובמיוחד לגיל היקום ולגיל כדור-הארץ, מעסיקות לא מעט אנשים (אם כי, האמת ניתנת להיאמר, מדובר בשתי דיסציפלינות שיכולות להתקיים זו לצד זו מבלי להתאמת ולהתעמת). מכיוון שהתרגלנו לראות ניסיונות "תיאום" כאלה מצד טוענים יהודיים ונוצריים, אולי כדאי לראות …

. לקריאה נוספת: מאמר מקיף בעברית על חומר ואנטי-חומר . Antimatter, a substance that often features in science fiction, is routinely created at the CERN particle physics laboratory in Geneva, Switzerland, to provide us with a better understanding of atoms and molecules. Now, RIKEN scientists, as part of a collaborative team with researchers from Denmark, …

. Understanding the transport of electrons in nanostructures and biological molecules behavior of molecules. However, determining whether the electrons are behaving according to the classical laws of motion or the quantum mechanical regime at the nanoscale is challenging because many nanostructures fall in a grey area between both regimes. Researchers from the RIKEN Advanced Science …
