- 1Significant Activity Identified at Iranian Nuclear Site Minzadayi▼Significant Activity Identified at Minzadayi, an Iranian Nuclear Weapons Development Site
The Institute for Science and International Security reports that significant activity has been identified at Minzadayi, a site it describes as linked to Iranian nuclear weapons development. The finding adds to ongoing scrutiny of undeclared or suspect nuclear facilities in Iran and is likely to fuel debate over Tehran's nuclear programme and international monitoring efforts.
- 2Fly Study Shows How Evolution Invents New Body Parts▼A ‘Male Organ’ for Flies Reveals How Evolution Invents New Body Parts
Researchers at the University of California, Davis report that a male-specific structure in flies offers new insight into how evolution generates entirely new body parts. The work, highlighted by UC Davis's College of Biological Sciences, suggests such organs can arise from the repurposing of existing genetic and developmental programs rather than from scratch, shedding light on one of biology's central questions.
- 3NOAA Names 2026 American Samoa Professional Development Instructors▼2026 American Samoa Professional Development Instructors
NOAA Ocean Exploration has announced the instructors selected for its 2026 American Samoa professional development program, which typically trains educators in ocean science and exploration. The announcement highlights continued investment in marine education in the Pacific territory, giving teachers hands-on experience with ocean exploration topics to bring back to their classrooms.
- 4Oklahoma State film 'Belonging' showcases classroom dynamics research▼'Belonging' film highlights Human Development and Family Science research on classroom dynamics
Oklahoma State University released a short film titled 'Belonging' that showcases research from its Department of Human Development and Family Science on classroom dynamics. The film highlights how the department's scholars study belonging and interpersonal relationships among students, translating academic findings into a format for wider audiences.
- 5Precision IVF tracks when mouse embryos switch on their genome▼Precision IVF tracks how mouse embryos switch on their genome
Researchers have used precision IVF techniques to observe the moment mouse embryos activate their own genome, a key early step in development. The work shows how fertilised eggs transition from relying on maternal material to running on their own genes. Scientists say the findings could sharpen understanding of early embryonic development and improve assisted reproduction methods.
- 6Earth and Mars Formed From Same Dust, Diverged Early●Earth and Mars Were Born From the Same Dust but Grew Up Completely Different
A new study argues that Earth and Mars formed from the same primordial cloud of dust in the early solar system, yet followed very different developmental paths. Researchers suggest differences in size, composition and early conditions drove the two planets onto sharply divergent evolutionary tracks, helping explain why only one became habitable. The findings are drawing attention among planetary scientists and space enthusiasts.
