Driven to regional extinction primarily by agricultural expansion and urban development, the non-migratory insect disappeared after its specialized oak-pine woodland ecosystems collapsed. Researchers are now pairing captive breeding programs with restored savanna grounds to establish a self-sustaining population. Led by ecologist Ryan Norris, the project will import specimens from New York to breed them at the Cambridge Butterfly Conservatory. The insects will eventually be released into Norfolk County, where former tobacco fields have been transformed into lupine-rich oak savanna habitats.

What if one day you discover the world has no butterflies? Their velvety wings, dashing through the garden, a moving pop of colour in a world of darkness.
Butterflies are not just there for aesthetic purposes. Their most important job is pollinating; a reduction in butterfly populations can mean a reduction in plant diversity, since wild plants and flowers will struggle to reproduce. They are also sensitive to environmental shifts. As bioindicators, they can help assess the health of the environment.
In Canada, a species of butterfly disappeared from Ontario in 1988 and has not been recorded there since. But now, nearly four decades later, it could flutter back. Scientists are preparing to bring it back, with plans to breed the butterflies in captivity and release them into restored habitats in the province.

Meet the frosted elfin (
Callophrys irus), a small, rather understated butterfly with delicate wings and a greyish-brown hue. Unlike its more flamboyant cousins, this species is not particularly colourful. Its…
Excavations in Pień led by Nicolaus Copernicus University have uncovered how early modern communities responded to fears of supernatural affliction. Researchers determined that physical illnesses in life likely led fearful villagers to modify the burial in two distinct stages. The discovery highlights how supernatural terror could override high social standing during seventeenth-century health crises.
Researchers from Cardiff University and Amgueddfa Cymru utilized advanced micro-CT scanning to expose the inner workings of an intact sixteenth-century maritime relic. The brass device originally belonged to the Ann Francis, a merchant vessel that foundered during a storm off the coast of Wales in December 1583. Discovered alongside coins and weights, the mechanism provides critical material evidence regarding how travelers safeguarded high-value cargo during cross-continental sea voyages.
University of Birmingham researchers devised an atomic system to track the sequence of events purely by measuring entropy changes rather than conventional ticks. This experimental environment operates on an internal timeframe that decouples entirely from external time whenever particle activity halts. The breakthrough offers a novel pathway to investigate long-standing theoretical conflicts between general relativity and quantum mechanics.
