As poultry companies weigh cost and efficiency with higher animal welfare standards, research comparing conventional and slow-growing broiler breeds showed that the slow-growing chickens displayed behaviors more closely associated with positive welfare.

Broilers — chickens specifically bred for meat production — are typically raised for six to eight weeks, while slow-growing broilers need up to 12 weeks to reach maturity.

A simple neural change alters mating preferences in male butterflies, aiding rapid behavioral evolution, Nicholas VanKuren and Nathan Buerkle at the University of Chicago, US, and colleagues, report March 11^th in the open-access journal PLOS Biology.

Brooklyn College/CUNY Graduate Center Associate Professor of Anthropology Stephen Chester and a team of researchers have uncovered fascinating new details about Mixodectes pungens, a long-mysterious mammal that roamed North America in the early Paleocene—just after the extinction of the dinosaurs.

A new study by scientists and graduates at the University of Plymouth has investigated one aspect of how the future environmental conditions created by the changing global climate might affect earliest development within Christmas Island’s red crab population

Researchers used in situ pH measurements and in situ UV-Vis spectroscopy to investigate the kinetically controlled growth of Co(OH)₂. They discovered that Co polyhedra with unconventional coordination play a crucial role in the formation process of Co(OH)₂, reshaping our understanding of the formation process.

Metabolic dysfunction-associated steatohepatitis (MASH) is a polygenic disorder influenced by multiple genes, but their specific roles in the progression of disease remain unknown. To address this gap, researchers conducted a series of experiments that identified the NACHT and WD repeat domain-containing protein 1 (Nwd1) gene and its role in liver pathogenesis. This breakthrough represents an important step toward establishing new therapeutic targets for MASH.
