A study led by Aarhus University finds male sperm whales' slow clicks exceed 200 dB and can carry up to 70 kilometers, the loudest mammalian communication signal recorded.

A UC Berkeley team built a 48-sensor computational microscope that hits 3-micron resolution across 5 square centimeters at 120 frames per second.

An 11-month dig at Vindonissa found the earliest camp's rampart, a legionary barracks, a field forge, and a Tiberius gold aureus.

Purdue researchers engineered a cobalt-aluminum intermetallic alloy that is 6 to 10 times stronger than structural steel while still bending under load.

Ultra-deep imaging from the Isaac Newton Telescope resolves IC 1101's faint outer edge at 520 kiloparsecs across, with 3.4 trillion solar masses in stars.

NTU Singapore researchers used the two-century-old Poisson spot phenomenon to generate optical skyrmions with a simple laser and disc, skipping costly metamaterials.

A new Astrophysical Journal study finds primordial black holes tunneling through white dwarfs could explain some Type Ia supernovae and Milky Way chemical patterns.

Viral DNA from two colonial-era mummies in northern Chile shows smallpox reached the Americas from Europe, in a newly named extinct lineage called CAM9.

Kyoto University researchers re-examined three 1990s fossils to identify a new genus of giant salamander that lived in Japanese lakes 3.5 million years ago.

A 2,000-year-old cemetery near Chelmsford holds five richly furnished cremation burials with imported Roman glass and wine jars, alongside three newly found Iron Age settlements.
