New theoretical predictions advance understanding of how heavy elements form in the universe
Researchers at TU Darmstadt developed theoretical predictions for beta-decay rates in neutron-rich nuclei, which are crucial to understanding heavy element formation in the universe. Beta-decay rates of extremely neutron-rich atomic nuclei have been difficult to measure experimentally, limiting models of element origin. These findings, published in Physical Review Letters, could refine scientific understanding of nucleosynthesis and the cosmic origins of heavy elements.
Scientists at TU Darmstadt have made progress in understanding how heavy elements form throughout the universe by developing new theoretical predictions for beta-decay rates in neutron-rich atomic nuclei. The research addresses a long-standing challenge in nuclear physics: determining the decay rates of extremely neutron-rich nuclei, which play a critical role in nucleosynthesis but have been difficult to measure directly in laboratory experiments. The team successfully compared their theoretical predictions with existing experimental data, validating their approach. These results, published in Physical Review Letters, could significantly improve models that explain the cosmic origins of heavy elements and the processes by which they are created in extreme astrophysical environments.
Limitations & open questions
The article does not specify which astrophysical environments (such as neutron star mergers or supernovae) are most relevant to these beta-decay processes, nor does it explain the practical implications for future experimental work or observational astronomy.

NASA Announces Artemis III Crew for Earth Orbit Test Flight
NASA announced on Tuesday that astronauts Randy Bresnik, Frank Rubio, Andre Douglas, and Luca Parmitano will fly the Artemis III mission, a two-week test flight scheduled for late 2027. Rather than landing on the moon, the crew will orbit Earth and practice docking their Orion capsule with lunar landers being developed by SpaceX and Blue Origin. This mission represents a critical step in NASA's broader Artemis program to return humans to the lunar surface for the first time since the 1970s.
Study Finds CFC Replacement Chemicals Creating Global 'Forever Chemical' Pollution
A new study published in Geophysical Research Letters estimates that chemicals used to replace ozone-damaging CFCs have deposited approximately 335,500 tonnes of trifluoroacetic acid (TFA), a persistent 'forever chemical,' onto Earth's surface between 2000 and 2022. TFA is a type of PFAS that resists breakdown and accumulates in the environment, with researchers detecting it in human blood and urine. The findings raise concerns about unintended consequences of chemical substitution and highlight the need for broader risk assessment in environmental regulation.
New Study Suggests Ancient Humans Transported Stonehenge's Altar Stone 700 Kilometers Across Britain
Researchers at Curtin University have concluded that the Altar Stone at Stonehenge's center was deliberately transported by ancient people across 700 kilometers from northeast Scotland, rather than carried by glaciers. The study combined mineral grain dating with computer models of ancient ice sheets to determine that while glaciers may have moved rocks partway during the last Ice Age, no viable glacial route could have delivered the stone to southern England. The findings suggest Neolithic communities possessed sophisticated planning and coordination capabilities to move a six-ton megalith across challenging terrain in multiple stages.
