Scientists identify previously unknown 'hybrid zone' between hummingbird species

We usually think of a species as being reproductively isolated—that is, not mating with other species in the wild. Occasionally, however, closely related species do interbreed. New research just published in The Auk: Ornithological Advances documents the existence of a previously undiscovered hybrid zone along the coast of northern California and southern Oregon, where two closely related bird hummingbirds, Allen's Hummingbird and Rufous Hummingbird, are blurring species boundaries. Researchers hope that studying cases such as this one could improve their understanding of how biodiversity is created and maintained.

To address hunger, many countries may have to increase carbon footprint

MRI-guided biopsy best for determining future risk of prostate cancer, study shows

Every year, tens thousands of men in the United States are diagnosed with low-risk prostate cancer. Most are told that they don't need treatment other than "active surveillance" to monitor their slow-growing tumors. Now, UCLA physicians have shown that the best way to proceed with this is by starting out with an MRI-guided prostate biopsy.

Childhood behavior linked to taking paracetamol in pregnancy

The research published today in Paediatric and Perinatal Epidemiology examined whether there were any effects of taking paracetamol in mid-pregnancy and the behaviour of the offspring between the ages of 6 month and 11 years, with memory and IQ tested up until the age of 17. Paracetamol is commonly used to relieve pain during pregnancy and is recommended as the treatment of choice by the NHS.

Obesity linked to a nearly 6-fold increased risk of developing type 2 diabetes

Obesity is linked to a nearly 6-fold increased risk of developing type 2 diabetes (T2D), with high genetic risk and unfavorable lifestyle also increasing risk but to a much lesser extent. These are the conclusions of new research presented at this year's Annual Meeting of the European Association for the Study of Diabetes in Barcelona, Spain (16-20 Sept), by Hermina Jakupovic, University of Copenhagen, Novo Nordisk Foundation Center for Basic Metabolic Research, Copenhagen, Denmark, and colleagues.

Latest studies suggest a possible downturn in rate of new cases of diabetes

While overall, the numbers (prevalence) of people with type 2 diabetes continue to grow at an alarming rate, new research presented at this year's annual meeting of the European Association for the Study of Diabetes (EASD) in Barcelona, Spain (16-20 September) shows that recent studies suggest the rate at which new cases develop (incidence) may be falling. The study is by Professor Dianna Magliano and Professor Jonathan Shaw, Baker Heart and Diabetes Institute, Melbourne, Australia, and colleagues.

Types and rates of co-existing conditions in diabetes are different for men and women
