Avian maternal response to chick distress A study has gained new insight into the minds of domestic hens, discovering, for the first time, that domestic hens show a clear physiological and behavioral response when their chicks are mildly distressed. The research by academics at the University of Bristol's Animal Welfare and Behavior research group, and funded by the BBSRC Animal Welfare Initiative, is published online in the Proceedings of the Royal Society B. The study is the first to...

A research group led by scientists from the University of Bristol has demonstrated the quantum operation of new components that will enable compact circuits for future photonic quantum computers. Quantum computers, holding the great promise of tremendous computational power for particular tasks, have been the goal of worldwide efforts by scientists for several years. Tremendous advances have been made but there is still a long way to go. Building a quantum computer will require a large number...

The growth in the demand of smartphones has highlighted the complexities of wireless communications through problems of reduced sensitivity when the user holds some devices. New research has been investigating this problem, along with developing new solutions to overcome the loss of connectivity. The study by academics in the field of antennas and propagation in the University of Bristol's Centre for Communications Research (CCR) is published in the journal IEEE Antennas and Wireless...

The specialist deblistering & leak testing company, Sepha Ltd. has won a major, new contract to supply an international consortium involved in a ground-breaking water testing project called Aquatest. The project involves the production of a simple, hand-held water testing device. The initial contract will see Sepha form, seal and leak test 50,000 blister packs containing Aquatest's active ingredients. The company will use their innovative blister packing and leak testing machines, EZ...

Boys and girls who take part in physical activity with their best friend in the neighbourhood where they live have higher levels of physical activity, new research has found. With many children not doing enough physical activity the findings could help with the UK's current health care concerns. The study examined the extent to which the physical activity modelling and physical activity actions of best friends are associated with the physical activity of 10- to 11-yr-old children. The paper,...

New research has found one of the smallest entities in the human genome, micro-RNA, could increase the risk of limb amputation in diabetic patients who have poor blood flow. The study by Dr Andrea Caporali and colleagues in Professor Costanza Emanueli's research group in the Regenerative Medicine Section of the School of Clinical Sciences at the University of Bristol was funded by the Medical Research Council and is published online in Circulation: Journal of the American Heart Association....

Researchers from universities in Scotland and England say that they have developed a new, highly accurate assessment for couples hoping to have a child through in-vitro fertilization (IVF). The experimental model, which was created by Scott Nelson from the University of Glasgow in Scotland and Debbie Lawlor from the University of Bristol in England, is currently available online and will soon be released as a smartphone app as well. The prediction model is also discussed in a paper published...
