Maximum entanglement sheds new light on the creation of particles
When an energetic quark or gluon is knocked freely during a proton-proton collision, this free “parton” first generates a shower of other partons, then “fragmented” to form hadrons (h), such as kons (k), pion (π), and protons (p). The higher the energy of the first quark or gluon, the higher the number of hadrons. If the hadron entropy is equal…

Broiler growth rate contributes to behavioral differences and sheds light on the impact on welfare
Credit: Pixabay/CC0 Public Domain Poultry companies weigh costs and efficiency on higher animal welfare standards, a study comparing traditional, growing broiler varieties has shown that slow-growing chickens exhibit behaviors more closely related to positive welfare. Chickens, specially raised for meat production, are usually grown for 6-8 weeks, but must grow up for up to 12 weeks to mature. Though popular…

Research sheds light on the use of multiple cubes for service and repair missions within the space
Meets collision prevention constraints while meeting the optimal fuel trajectory of four service agents transporting modular components between the service vehicle and the target spacecraft. Credit: Journal of Space Flight Science (2024). doi:10.1007/s40295-024-00470-7 As more satellites, telescopes, and other spacecraft are built to be repairable, a reliable trajectory will be required for service spacecraft to reach safely. Researchers from the…

International collaboration sheds new light on the relationship between quantum theory and thermodynamics
There is no quantum disease in Maxwell’s demon (but that’s not necessary). Credit: Reiko Matsushita Researchers from Nagoya University in Japan and the Slovak Academy of Sciences have published new insights into the interaction between quantum theory and thermodynamics. The team demonstrated that quantum theory essentially does not prohibit violations of the second law of thermodynamics, but that quantum processes…

Surprising discovery sheds light on the cause of Huntington’s disease, a deadly brain disorder
This micrograph provided by the Harvard Brain Tissue Resource Center at McLean Hospital in January 2024 shows cells within the caudate nucleus structure of the brain of a patient with Huntington’s disease. Credit: Harvard Brain Tissue Resource Center at McLean Hospital/NIH NeuroBioBank (via AP) Scientists are unraveling the mysteries that trigger Huntington’s disease. Huntington’s disease is a devastating and fatal…

Fossil discovery sheds light on the early evolution of animal nervous systems
An incomplete tubular specimen of the Eopliaprites sphinx excavated from the Quang Tuanh Formation of the Early Cambrian. The ventral nerve cord is shown. Credit: Science Advances (2025). DOI: 10.1126/sciadv.adr0896 An international team of scientists has solved a fascinating piece of the evolutionary puzzle. That’s how the ventral nerve cord, a key component of the central nervous system, evolved in…

Ancient DNA sheds light on hidden European migrations of the first millennium AD
The paper identifies three waves of migration across Europe. Credit: Leo Speidel, Francis Crick Institute A study led by the Francis Crick Institute, using a more precise method of analyzing ancestry using ancient DNA, has revealed that there was a wave of human migration across Europe in the first millennium AD. Researchers can piece together how people moved around the…

The moon may be older than scientists previously thought. New research sheds light on its history
Credit: Pixabay/CC0 Public Domain Physicists, chemists, and mathematicians walked into the bar. It sounds like the beginning of a bad joke, but in my case it was the beginning of an idea that could change the way scientists think about the history of the moon. All three of us were interested in the moon, but from different perspectives. As a…

Sustainable groundwater withdrawal rates in Oregon’s Harney Basin were higher than they were 20 years before groundwater levels were generally acknowledged to be declining, a new analysis finds. Lagging recognition of the impacts of groundwater use is just…
