Advanced composite materials are playing a vital role in improved design and reduced operating costs for renewable energy technologies. Research presented today [Tuesday 30 June] will highlight how wind, marine and solar power could address these challenges within the renewable energy industry.
A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light -- photons -- on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements.
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibres with high fidelity.
The only quantum technology in practical use today is quantum cryptography and is currently limited in the distance over which secure communication may occur.
Contrary to popular belief, aggressive dogs are NOT trying to assert their dominance over their canine or human "pack", according to research published by academics at the University of Bristol's Department of Clinical Veterinary Sciences in the Journal of Veterinary Behavior, Clinical Applications and Research.
Treatment of chronic wounds is a continuing clinical problem and socio-economic burden with diabetic foot ulcers alone costing the NHS GBP300 million a year. Scientists in Bristol have found that human foetal stem cells can effectively be used to treat back leg ischaemic ulcers in a model of type 1 diabetes.
Two members of the University of Bristol Spelaeological Society have discovered an engraving in a cave in the Mendip Hills, Somerset, which may be at least 10,000 years old. Graham Mullan and Linda Wilson, who have spent much of the last ten years studying Palaeolithic cave art, recently began a systematic search of caves in southern Britain in the belief that such works in this country would not simply be confined to those found at Creswell Crags, Nottinghamshire.
Cooling the brains of babies deprived of oxygen at birth can reduce the risk of brain damage and cerebral palsy, according to an international study published today (January 28) in the Lancet on-line. To achieve cooling, the body temperature of babies in the trial was lowered by 3-4 degrees for 72 hours after birth using a water-filled cap.
The research was undertaken in hospitals in North America, New Zealand and the UK, and the UK arm of the trial was carried out in University College London Hospital, the University of Bristol at St Michael's and Southmead Hospitals, and Imperial College London at Hammersmith Hospital.
The recent rise in obesity may be partly due to the reduced amount of time we spend asleep, according to new research from the University of Bristol, UK. Dr Shahrad Taheri from Bristol University, and colleagues in the United States, examined the role of two key hormones that are involved in regulating appetite -- ghrelin and leptin. Ghrelin increases feelings of hunger while leptin acts to suppress appetite. People who habitually slept for 5 hours were found to have 15% more ghrelin than those who slept for 8 hours. They were also found to have 15% less leptin. These hormonal changes may cause increased feelings of hunger, leading to a foraging in the fridge for food.
Cosmetic face cream used by fashionable Roman women has been analysed by scientists at Bristol University, UK, and then reproduced. Cosmetic face cream used by fashionable Roman women has been analysed by scientists at Bristol University, UK, and then reproduced. The results of this unique opportunity to analyse the ingredients of the 'foundation' cream are reported in Nature this week.
Scientists at Bristol University have found that a protein present in normal body tissues can prevent tumour growth. A team there discovered that a type of vascular endothelial growth factor found in normal tissue, including blood, can prevent cancers from growing. The growth of any cancer depends on its ability to maintain a blood supply that will deliver nutrients. For a cancer to grow from the size of a pinhead to that of a golf-ball, the blood supply of the tumour has to grow with the expansion of the tumour itself.
