DNA profiling reveals grey squirrels are not as good invaders as we think, and that humans played a much larger role in spreading them through the UK.

Grey squirrels were imported to the UK from the 1890s onwards, and the traditional view is that they spread rapidly across the UK due to their ability cope with new landscapes. Different populations of grey squirrels were thought to have interbred into a 'supersquirrel' that was better able to adapt and spread.

In October 2015, a team of researchers at the University of Wisconsin-Madison and Universidad de Sucre in Colombia ran the first tests confirming the presence of Zika virus transmission in the South American country.

In a study published today [Jan 26, 2016] in the journal Emerging Infectious Diseases, the team documents a disease trajectory that started with nine positive patients and has now spread to more than 13,000 infected individuals in that country.

"Colombia is now only second to Brazil in the number of known Zika infections," says study lead author Matthew Aliota, a research scientist in the UW-Madison School of Veterinary Medicine (SVM).

Antihydrogen is a particular kind of atom, made up of the antiparticle of an electron - a Positron - and the antiparticle of a Proton - an antiproton. Scientists hope that studying the formation of anti hydrogen will ultimately help explain why there is more matter than antimatter in the universe. In a new study published in EPJ D, Igor Bray and colleagues from Curtin University, Perth, Australia, demonstrate that the two different numerical calculation approaches they developed specifically to study collisions are in accordance. As such, their numerical approach could therefore be used to explain antihydrogen formation.

New research has found, for the first time, a scientific solution that enables future internet infrastructure to become completely open and programmable while carrying internet traffic at the speed of light.

The research by High Performance Networks (HPN) group in the University of Bristol's Department of Electrical and Electronic Engineering is published in the world's first scientific journal Philosophical Transactions of the Royal Society A.

The current internet infrastructure is not able to support independent development and innovation at physical and network layer functionalities, protocols, and services, while at the same time supporting the increasing bandwidth demands of changing and diverse applications.

Data sharing in medical research could soon become the norm, according to a series of articles published this month in PLOS Medicine. The papers, representing authors from the World Health Organization, the pharmaceutical corporation GlaxoSmithKline, the US National Library of Medicine, and the International Committee of Medical Journal Editors, and summarized in an Editorial by the PLOS Medicine Editors, discuss recent progress towards acceptance of data sharing, in particular for research related to public health emergencies, and for reports from clinical trials. The Editorial discusses the challenges that remain, including the need to ensure that researchers who share data receive appropriate recognition.

Women who began having menstrual cycles at a younger age are at greater risk of developing gestational diabetes, a disease affecting up to 7 percent of pregnant women that can cause babies to develop type 2 diabetes and other complications, new research shows.

Previous research has shown an association between beginning menstrual cycles, or menarche, at a young age and the development of type 2 diabetes. However, the new study, published in Diabetes Care, a peer-reviewed journal of the American Diabetes Association, looked specifically at menarche and gestational diabetes, a type of diabetes that begins or is first recognized during pregnancy.
