The seventh session of the United Nations Environment Assembly (UNEA-7) concluded in Nairobi, Kenya, on Friday with Member States adopting 11 resolutions, three decisions and a ministerial declaration aiming to advance solutions for a more resilient planet. Continue Reading
Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome separation during cell division. By studying related yeast species, researchers found centromeres that appear to represent evolutionary halfway points. These structures seem to have formed from retrotransposons—mobile “jumping genes” in the genome. TheContinue Reading

Download PDF: Insights into Spallation Mechanisms of Thermal Protection System Materials from Mass Spectrometry and HyMETS Testing An effort was undertaken to investigate the mechanisms responsible for internal pressure build up within thermal protection system (TPS) materials subjected to high-enthalpy environments. Understanding how gases evolve, migrate, and interact with the microstructure ofContinue Reading
Download PDF: Computational Modeling of Failure at the Fabric Weave Level in Reentry Parachute Energy Modulators Energy modulators (EM) are textile mechanical devices designed to dissipate snatch loads that occur when parachutes are deployed. Although critical for mitigating shock loads, recent flight testing has shown increasing variability in EM behavior, raising concernsContinue Reading
