Camouflaged creatures can perform remarkable disappearing acts but new research shows that predators can learn to read camouflage.

The study, which used human subjects as predators searching for hidden moths in computer games, found that the subjects could learn to find some types of camouflaged prey faster than others.

The research was carried out by the University of Exeter and the University of Cambridge and is published in the journal PLOS ONE. Moths with high contrast markings – that break up the shape of the body, like that of a zebra or giraffe – were best at evading predation at the start of the experiment. However humans learnt to find these prey types faster than moths with low contrast markings that match the background, like that of a stick insect or leaf bug. (more…)

Young people who identify as lesbian, gay or bisexual are twice as likely to have smoked than their heterosexual peers, according to new research published in BMJ Open. Lesbian and gay young people were also more likely to drink alcohol frequently and more hazardously.

The interdisciplinary research team comprised researchers from five UK Universities (UCL, University of Cambridge, London Metropolitan University, De Montfort University Leicester and Brunel University), a doctor working in General Practice and a consultant from Public Health England. (more…)

AUSTIN, Texas — Seed size is controlled by small RNA molecules inherited from a plant’s mother, a discovery from scientists at The University of Texas at Austin that has implications for agriculture and understanding plant evolution.

“Crop seeds provide nearly 70 to 80 percent of calories and 60 to 70 percent of all proteins consumed by the human population,” said Z. Jeff Chen, the D.J. Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin. “Seed production is obviously very important for agriculture and plant evolution.” (more…)
