Evolution has repeatedly turned hawkmoth genitals into defensive tools

The genital structures of male hawkmoths are lifesavers. By rubbing specialized scales on their genitals against parts of their abdomen, the nocturnal insects emit ultrasonic sounds that can potentially scramble the acoustic signals that bats use to hunt.

Bio-based smart coating combines fire protection, early warning and upcyclability
Researchers have developed a multifunctional fire-protective coating that not only shields materials from extreme heat but also provides an early warning of fire and can be recycled into new flame-retardant materials at the end of its life. The work, published in Polymer Degradat

New research uncovers chiral topological phases in metals without structural order
Fermions are among the most important particles in physics and include both everyday electrons and more exotic variants. Chiral fermions, like gloves, come in left- and right-handed versions and were proposed over a century ago. While high-energy neutrinos—the leading candidates

A cosmic 'leaf blower': Light-propelled winds help explain early universe's bright galaxies
When astronomers looked at photos of the early universe taken by the James Webb Space Telescope, they found something odd: an overabundance of bright galaxies. Based on what they knew about the early universe, such galaxies should have been far less common in the few hundred mill

Mitigating the ecological consequences of light pollution
Light pollution is one of the fastest-growing and least-regulated environmental changes worldwide. It disrupts biological processes at all levels—from genes to entire ecosystems—and contributes significantly to global biodiversity loss. A recent review article, in which the Leibn
