Stunning Close-Up of Spider Silk Earns Scientific Photography Award

The silk threads, surrounded by finer looped strands, originate from Australian cast-net spiders (Asianopis sublufa), known as exceptional ambush predators. Instead of crafting a web and waiting for their prey, these spiders utilize their four front legs to control the web and ensnare their unfortunate target. This electron microscopy image reveals the spider’s silk, which is uniquely tailored for this peculiar hunting method. The silk structure features an elastic core enveloped in a sheath of firmer fibers of varying thicknesses, ensuring it is both robust and highly flexible.

The photograph was captured by Martin J. Ramirez, whose team at Argentina’s Bernardino Rivadavia Museum of Natural Sciences clinched the top prize at the 2025 Royal Society Publication Photography Competition.

The standout photo in the behavior category depicts a confrontation between two male prairie chickens (Tympanuchus cupido). Captured by Peter Hudson from Pennsylvania State University, this image illustrates the males gathering in leks during mating season, engaging in aerial displays to compete for female attention.

Filippo Carugati from the University of Turin, Italy, earned recognition in the Ecology and Environmental Sciences category for capturing this tadpole during an expedition in Madagascar. This juvenile is believed to be a Gibemantis liber, residing in a gelatinous substance that clings to tree trunks.

The image was taken by Irina Petrova Adamatzky, a UK-based photographer and runner-up in the behavioral category. The Atlas moth (Attacus atlas), one of the largest moth species globally with wingspans reaching up to 30 centimeters, exhibits remarkable mimicry that resembles snake heads at the tips of its wings, providing camouflage against avian predators.

In Chile’s Atacama Desert, stratocumulus clouds that flow in from the coast serve as a vital resource. Felipe Ríos Silva, a professor at the Pontifical Catholic University of Chile, is investigating ways to capture this fog and convert it into potable water for residents living in one of Earth’s driest regions. His photo earned him the runner-up spot in the Earth Science and Climatology category.

This photograph captures the sun’s emergence after six months of darkness in Antarctica. Dr. Aman Chokshi, a runner-up in the astronomy category at McGill University in Canada, braved brutal -70°C (-94°F) winds and heated his camera to take a 360-degree panoramic shot of the horizon as the sun rose, transforming it into a three-dimensional image that resembles a small planet encircled by green and purple auroras alongside the Milky Way.
