Urbanization in China has considerably exacerbated the warming experienced by a large majority of the population, according to the authors of a new study. The authors conclude urbanization accounts for about one third of China’s observed warming. Researchers quantified the separate contributions of urbanization and other external forces to the observed warming in China. Using […]

Knowing your risk won’t change your behaviour
Increasingly genetic tests are being offered that suggest if you know your risk for something, you’ll be more likely to change your behaviour; but new research is suggesting this isn’t the case. In a review study authors found having information genetic risk had little or no effect on people’s diet, or smoking or exercise habits. […]
Cheetahs’ genome give glimpse into their history, adaptation and survival
Genetic analysis has uncovered new details about the history, adaptation and survival of the world’s fastest land animal, the cheetah. The cheetah is descended from a relative of the American puma, and 100,000 years ago could be found across the Americas before moving into Asia and Europe. The results of the genomic analysis have pinpointed […]
How to teach students to think critically
Allowing students to make, and act on, quantitative comparisons between sets of data, helps them evaluate models more effectively, new research indicates. In an introductory physics laboratory course students were instructed to make and act on comparisons between datasets, and between data and models – an approach common in many areas of science. By the end of […]
Wild salmon reproduce better than hatchery ones
Hatchery salmons are often introduced into rivers to support wild populations, which are in a state of decline. Yet hatchery males have lower reproductive success than wild ones, according to a study of 196 Coho salmons (Oncorhynchus kisutch). When occupying the same position in the spawning hierarchy, hatchery males have only 55 to 84 per […]
Music can transcend culture
Montreal hipsters’ and Congolese pygmy tribe members react to some elements of music in the same way, according to a new study. Forty Pygmies and 40 Canadians listened in pairs to 19 music excerpts (eight Pygmy and 11 Western instrumental excerpts) and were asked to rate the songs (arousing or calming, positive or negative.) Researchers found […]
