Utah's wildlife agency captured, assessed and released a record 1,901 wild animals during the 2024-25 winter, using health checks and GPS collars to study the state's herds.
A Physikalisch-Technische Bundesanstalt collaboration combined precision acoustics with MEG and fMRI and found the human auditory cortex responds to infrasound below the classical 16 Hz limit, matching a proposed cochlear mechanism in which outer hair cells generate the signal the inner ones cannot.
A revised counting method just shrank Montana's wolf population by hundreds on paper, raising questions about which number—if either—reflects reality.
Project RattleCam has recorded newborn rattlesnakes on all three of its livestreams in one season for the first time, on 30 July in California, 11 August in Colorado and 8 September in Pennsylvania. More than 60 newborns have been observed in Colorado. Iris was first seen in California, as a baby, in 2021.
A city-state with no room to spare solved its garbage crisis by building a landfill in the ocean, then doubling down.
The American Beefalo Association defines the breed as three-eighths bison. A genome-wide survey of frozen semen, drawn largely from animals collected at or near the founding of the breed, found that not one Beefalo in the data set meets the standard, and found zebu ancestry in the genomes that the paper says the pedigrees do not report.
A student at the University of Oklahoma spotted pinhead-sized structures on a crinoid fossil sitting in a small Montreal museum. They turned out to be the tube feet of Dendrocrinus simcoensis — only the second crinoid ever found with preserved soft tissue, and the oldest by more than 200 million years.
A flat-topped volcanic sheet holds clues to how fast ancient mountains were rising—and suggests the Andes grew slower than once thought.
A 100-million-cubic-metre-per-second Zanclean flood is a modelled explanation for buried erosion, but the Mediterranean's starting depth and refill sequence remain contested.
Burning Mountain is not a volcano but a buried coal fire, reconstructed from kilometres of heat-altered ground and still moving south beneath a New South Wales reserve.
Scientists discovered that mixing sheep's wool and seaweed polymer into clay could double the material's strength without any kiln firing—potentially transforming how we build with earth.
The high tanks held 10,000 nanograms of caffeine per litre and the low tanks held 100, two levels chosen because both occur in real rivers. There was no caffeine-free group at all, so what the experiment measures is the distance between those two numbers.
The reduction appears to be unique in the millipede order Polydesmida, and in both known adult females the flattened leg bases sit over the vulva like a lid. More than forty adult males came out of the same litter sample, and two adult females.
A new Chicxulub model adds fine silicate dust to the returning-ejecta heat pulse, then follows the same dust into the prolonged darkness that battered surviving food webs.
Discarded oyster shells absorb rare earth metals at rates exceeding their own weight, suggesting an unlikely solution to cleaning up industrial contamination.
Ol Doinyo Lengai’s 500–590°C carbonate lava flows black, then atmospheric moisture and rain transform its unstable minerals into pale, rapidly weathering surfaces.
