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.

All lifeforms need to continuously adapt to temperature changes to survive. Now, Weill Cornell Medicine investigators studying a bacterial protein have identified a new mechanism of sensing cold temperatures. The finding points to the possibility that this same type of mechanism exists in other organisms, including humans, and may have relevance for disorders involving faulty temperature regulation.

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.
