Methane Reservoir Beneath Antarctic Ice Sheet
2012-08-30 08:32:12

April Flowers for redOrbit.com - Your Universe Online A recent study of the Antarctic Ice Sheet suggests that it could be a largely overlooked source of the potent greenhouse gas methane. An international team of scientists from the University of Bristol, the University of California, Santa Cruz, the University of Alberta, Edmonton, and the University of Utrecht, demonstrate that old organic matter in sedimentary basins located beneath the Antarctic Ice Sheet may have been converted to...

What Did The Jurassic Age Diplodocus Eat?
2012-07-31 08:46:03

April Flowers for redOrbit.com - Your Universe Online A team of researchers from the University of Bristol, Natural History Museum of London, the University of Missouri and Ohio University report they have discovered the eating habits of the Jurassic age dinosaur, the Diplodocus. Found nearly 130 years ago, the eating habits of the giant herbivore were still largely uncertain until now. Understanding these habits could provide insights into extinct ecosystems and today's modern animal...

The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models. The process, named 'saddle-collapse', was found to be the cause of two rapid sea level rise events: the Meltwater pulse 1a (MWP1a) around 14,600 years ago and the '8,200 year' event. The research is published today in Nature. Using a climate model, Dr Lauren Gregoire of Bristol's School of Geographical Sciences and colleagues unearthed the series of...

The influence of aerosols (small particles less than 1 micrometer in diameter) and clouds (liquid droplets 1 — 1000 micrometers diameter) represents one of the largest uncertainties in our understanding of trends in past global climate and predicting future climate change, as recognized by the 2007 report of the Intergovernmental Panel on Climate Change. One of the most significant 'known unknowns' is how quickly water can condense on the small aerosol particles to grow and become...

Computer chips of a type more commonly found in games consoles have been used by scientists at the University of Bristol to reveal how the flu virus resists anti-flu drugs such as Relenza and Tamiflu. Professor Adrian Mulholland and Dr Christopher Woods from Bristol´s School of Chemistry, together with colleagues in Thailand, used graphics processing units (GPUs) to simulate the molecular processes that take place when these drugs are used to treat the H1N1-2009 strain of influenza...

A true obesity epidemic is gradually advancing throughout the developed world. A large new Danish-British study from the University of Copenhagen and University of Bristol documents for the first time a definite correlation between a high BMI and the risk of developing life-threatening cardiac disease. Heart attack, atherosclerosis of the coronary arteries and angina — also called ischemic heart disease — are the most common causes of death in adults worldwide. In the US alone,...

Courtship In The Cricket World
2012-04-30 14:20:09

Everyone wants to present themselves in the best light - especially when it comes to finding a partner. Some rely on supplying honest information about their attributes while others exaggerate for good effect. A new study by researchers at the University of Bristol, published in PNAS, has discovered how male crickets could use similar tactics to attract a mate. Male crickets advertise for mates by singing loud repetitive songs at night. They rub their wings together, setting them into...

Evidence that a Florentine merchant house financed the earliest English voyages to North America, has been published on-line in the academic journal Historical Research. The article by Dr Francesco Guidi-Bruscoli, a member of a project based at the University of Bristol, indicates that the Venetian merchant John Cabot (alias Zuan Caboto) received funding in April 1496 from the Bardi banking house in London. The payment of 50 nobles (£16 13s. 4d.) was made so that 'Giovanni...

The tiny teeth of a long-extinct vertebrate — with tips only two micrometers across: one twentieth the width of a human hair — are the sharpest dental structures ever measured, new research from the University of Bristol and Monash University, Australia has found. For 300 million years, Earth´s oceans teemed with conodonts — early vertebrates that kept their skeleton in their mouth.  The elements of this skeleton look uncannily like teeth (see image) and, like...

Unearthed Burial Grounds Provide Look Into Slave Trade
2012-03-11 06:05:15

A slave burial ground in St Helena has been unearthed and discovered by archeologists from the University of Bristol. The burial ground was discovered in the South Atlantic Island as construction for a new airport and roads continues. Archeologists now look to the burial ground to tell the story of the Middle Passage during the Atlantic slave trade. St Helena is located 1,000 miles off the eastern shore of Africa. The island became famous for being a landing place for many freed slaves...
