Cold-triggered ion channel in bacteria may point to broader temperature-sensing mechanism

Arctic glacial fjords are hotspots of marine life, yet their seafloor environments remain some of the least explored regions on Earth. Their extreme remoteness and the technical challenges of deep-water observation have led scientists to rely on indirect measurements like sonar. However, these methods cannot visually verify animal behavior or identify specific species.

Meeting future nickel demand for stainless steel and clean energy technologies will require tough decisions with potential environmental trade-offs, a new study has found. Dr. Jayden Hyman from The University of Queensland's School of the Environment led an international analysis of known nickel deposits, current mining and demand forecasts.

New research led by Prof. Gurit Birnbaum, a researcher of sexuality in close relationships at Reichman University's Baruch Ivcher School of Psychology, and conducted in collaboration with her graduate student Kobi Zholtack and Prof. Harry Reis of the University of Rochester, examines how sexualized online dating profiles shape viewers' perceptions and relationship intentions.

New research finds that higher temperatures can actually benefit some bumble bee species—particularly those that make subterranean nests. However, periods of extreme heat appear to offset those benefits, and may contribute to declining bumble bee populations in the southeastern United States. The paper, "Nesting biology shapes climate vulnerability of social bees (Bombus spp.)," is published in the Journal of Animal Ecology.
