A study of 24 colonies in New South Wales found that antimicrobial activity of hive materials declines from outer to inner compartments and acts mostly on bacteria.
Chalmers researchers built two statistical models on Swedish truck data for 2016–2019. Empty containers were 44–46% of vehicles and 32–33% of vehicle kilometres.
Drone counts of the entire range in 2022–2024 found about 27,800 breeding pairs on the Bounty Islands and 29,800 on the Antipodes, with opposite population trends.
The California Insect Barcode Initiative reports that only about two-thirds of the state's insect species are described; over one million specimens were DNA barcoded.
Long-term records from the La Selva and El Verde field stations show more extreme heat days by 2024, while rainfall trends differ between the two sites, the authors report.
In Drosophila erecta, food volatiles trigger male sexual arousal and start a visual feedback loop across the group. D. melanogaster does not depend on them for courtship.
Satellite records since 2001 show planted forests in temperate regions burned more often and over larger areas, but the effect varied by biome, from a near-threefold rise to an 18% drop.
Bryan Jennings proposes that a change in body size can alter trait proportions before related species compete. The theory draws on measurements of preserved lizards.
Evolution-informed and rational design were combined to engineer PET hydrolases; in vitro, many variants approached the LCC-ICCG benchmark in partial conversion.
Chinese researchers made a laboratory CoO mesocrystal catalyst that resists water poisoning; the authors report it also worked at −5 °C and in a 3 m3 room.
Researchers from Yale and Cornell trained models on Chinese data and applied them to South Korea and Iran; the authors propose the method for near-real-time tracking of industrial activity.
A modeling-based review of hydrogen export projects in North Africa, Chile and Australia finds water withdrawal far above the stoichiometric nine litres per kilogram.
Researchers in India built a lab microbial fuel cell with a binder-free iron-nickel carbon nanofiber electrode. It treats sewage, degrades an antibiotic and produces hydrogen peroxide.
Fossils of the Early Cretaceous Paja Formation in Colombia show a complex food web with many apex predators. The authors suggest major evolutionary shifts can occur without a mass extinction.
Analysis of 12,813 DNA sequences points to hidden diversity in at least one-fifth of recognized taxa; most complexes are projected to lose over 50% of suitable habitat by 2070.
Researchers analysed 356 pregnancies, including 52 miscarriages, in a group of about 300 mandrills in Gabon observed for 11 years, and compared reproductive success.
Nest lining of Colletes inaequalis bees from one nesting site lost part of its polyester in soil over months; the degradation mechanism is still unknown.
