  Filmmaker Patrick Willems explores the phenomenon of movies that, despite being popular and successful upon release, seem to vanish from cultural memory and conversation. He examines potential reasons for this "half-life" effect, including shifts in comedic sensibilities, evolving social and political contexts that render certain jokes or themes problematic, and the oversaturation of media making it harder for any single work to maintain relevance. Willems uses the 2004 comedy "Dodgeball: A True Underdog Story" as a primary case study, highlighting how its humor, once widely accepted, might be perceived differently today. He concludes that while some films genuinely age poorly, the cultural half-life is a complex interplay of various factors that can lead to even well-regarded movies fading from the spotlight.

  Scientists have measured the half-lives of superheavy elements moscovium, nihonium, and tennessine, providing crucial insights into the stability of these synthetic elements at the edge of the periodic table. Using a new detection system at the GSI Helmholtz Centre for Heavy Ion Research, they found slightly longer half-lives than previously estimated, bolstering theories about an "island of stability" where superheavy nuclei with longer lifespans could exist. These measurements contribute to a better understanding of nuclear structure and the forces governing these extreme atomic nuclei.

  In a significant advancement for nuclear physics, a team of researchers at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, has achieved a groundbreaking feat: measuring the half-lives of two superheavy elements, moscovium (element 115) and nihonium (element 113), with unprecedented precision. These elements reside at the extreme edge of the periodic table, in a region where the nuclei of atoms are so massive and laden with protons that they teeter on the brink of instability, rapidly decaying into lighter elements. This inherent instability makes studying these elusive elements extraordinarily challenging.

  The experiments, meticulously detailed in a recent publication in Physical Review Letters, involved the intricate process of creating these superheavy elements through nuclear fusion reactions. Specifically, accelerated beams of calcium-48 ions were bombarded onto thin target foils of americium-243 to synthesize moscovium and neptunium-237 to synthesize nihonium. These collisions, occurring at carefully calibrated energies, resulted in the fleeting formation of the target superheavy nuclei.

  Following their creation, the newly formed atoms were separated from other reaction products using the GSI's velocity filter SHIP, which selectively transmits ions based on their velocity and charge. The filtered superheavy atoms were then implanted into silicon detectors, meticulously designed to register the energy and timing of their subsequent radioactive decays. These decays, occurring through alpha particle emission, served as the critical data points for determining the half-lives of the elements.

  The team's measurements reveal half-lives of approximately 16 milliseconds for moscovium-288 and 18 milliseconds for nihonium-284, providing critical insights into the stability and nuclear structure of these exotic elements. These meticulously conducted experiments represent a substantial leap forward in our understanding of the so-called "island of stability," a theoretical region within the chart of nuclides where superheavy elements are predicted to exhibit significantly longer half-lives than their lighter counterparts. The new data not only push the boundaries of our knowledge of nuclear stability but also provide invaluable benchmarks for refining theoretical models of nuclear structure, allowing scientists to more accurately predict the properties of even heavier, as yet undiscovered elements. This information will guide future experiments aimed at synthesizing and characterizing these ephemeral giants of the periodic table, potentially unveiling the true extent and nature of the theorized island of stability. The research also underscores the continued importance of advanced experimental techniques and facilities like the GSI in pushing the frontiers of scientific discovery in the realm of nuclear physics.
