Abstract The Serrote do Letreiro Site, found on the northwest periphery of the Sousa Basin, Brazil, presents a remarkable convergence of paleontological and archaeological elements. It is constituted of sub-horizontal “lajeiros”, or rock outcrops, intermingled with endemic Caatinga vegetation. The three prominent outcrops feature fossilized footprints of theropod, sauropod, and iguanodontian dinosaurs from the Early Cretaceous…

In addition to the usual dose of compelling science, our March issue features thoughtful reflections on the last 30 years from readers, as well as past and present editors. Perhaps influenced by these pieces or by our stunning cover — or maybe it is just the changing seasons — we are in an introspective mood…

Abstract In the continuous pursuit of enhancing the sensitivity of nanophotonic biosensors by leveraging phase phenomena, a recent development involved the engineering of an atomically thin Ge2Sb2Te5 layer on a silver nanofilm to generate large Goos–Hänchen-shifts associated with phase singularities. The resulting detection limit reached ~7 × 10−7 RIU. Early developments in nanophotonic biosensing focused on exploiting…

Scientists from the NUS have created a novel method for fabricating quantum materials at the atomic scale using AI, offering significant advancements in the control and production of these materials for research and practical applications. This method, involving the CARP concept, demonstrates the potential for AI to revolutionize atomic manufacturing and quantum material research. (Artist’s…

A sperm whale calf nursing from its mother, a great blue heron gobbling up a fishy breakfast, and a pair of otters splashing in the water: The wildlife images from the 2024 Sony World Photography Awards showcase the tenderness, brutality, and beauty of the animal kingdom. This week, the World Photography Organisation announced the year’s category winners…

Hawai’i is home to a broad, beautiful array of bird species found only on its islands — like the stunningly diverse honeycreepers, many on the border of extinction. Now, a local team is removing invasive predators, restoring habitats, and battling mosquito-borne diseases to protect honeycreepers from their latest threat: avian malaria.
