Science and policy intersected in striking ways today, from prehistory to the supermarket shelf. Researchers revisited one of Britain’s oldest mysteries, weighing whether Stonehenge’s six-tonne altar stone could have been carried from north-east Scotland by glacial action rather than by human transport, though the evidence remains contested. In a more modern bid to cut environmental impact, Sainsbury’s said it will shift its own-brand eggs from brown to white shells, arguing the smaller hens that lay white eggs consume less feed and lower emissions. Energy infrastructure also drew attention in Nigeria, where the regulator ordered compensation for eligible Band A customers after power shortfalls linked to generation constraints, gas supply problems and vandalism. Elsewhere, a U.S. watchdog report raised fresh concerns over detainee treatment and safety at a Louisiana ICE facility, underscoring how questions of evidence, accountability and systems failure continue to shape the day’s headlines.
