The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of the Earth's temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising.
Latest research into the age of volcanos in Western Victoria and South Australia has confirmed that the regions are overdue for an eruption, potentially affecting thousands of local residents.
Using the latest dating techniques, scientists from the University of Melbourne's School of Earth Sciences and the Melbourne School of Engineering have calculated the ages of the small volcanoes in the regions and established the recurrence rate for eruptions as 2,000 years.
raphene, discovered in 2004 at The University of Manchester by Professor Andre Geim and Professor Kostya Novoselov, is one of the world's most versatile materials, and is already being used in such varied applications as touch screens, transistors and aircraft wings.
Researchers from the University are presenting the vast potential of the wonder material at the Royal Society's annual Summer Science Exhibition which opens today (5 July 2010).
US and Swiss researchers have, for the first time, modelled a climate system with extremely high carbon emissions in an attempt to test the boundaries of the current computer simulation programs that inform us.
Published today, Tuesday 5 July, in IOP Publishing's journal Environmental Research Letters, the study has revealed the potentially devastating effects that high carbon emissions could have on our climate.
Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. Such melting would increase the sea level more than already projected.
The research, based on 19 state-of-the-art climate models, proposes a new mechanism by which global warming will accelerate the melting of the great ice sheets during this century and the next.
The Mary river turtle (Elusor macrurus), which is restricted to only one river system in Australia, will suffer from multiple problems if temperatures predicted under climate change are reached, researchers from the University of Queensland have shown.
The scientists, who are presenting their work at the Society for Experimental Biology Annual conference in Glasgow on 3rd July 2011, incubated turtle eggs at 26, 29 and 32⁰C. Young turtles which developed under the highest temperature showed reduced swimming ability and a preference for shallower waters.
College Park, Md. (July 1, 2011) -- Ever since an ordinary office inkjet printer had its ink cartridges swapped out for a cargo of cells about 10 years ago and sprayed out cell-packed droplets to create living tissue, scientists and engineers have never looked at office equipment in quite the same way. They dream of using a specialized bio-inkjet printer to grow new body parts for organ transplants or tissues for making regenerative medicine repairs to ailing bodies. Both these new therapies begin with a carefully printed mass of embryonic stem cells.
Researchers can now see objects more precisely and faster at the nanoscale due to utilising the full colour spectrum of synchrotron light, opening the way for faster 3D nanoimaging.
This new methodology will provide for enhanced nanoimaging for studying bio samples for medical research, improved drug development and advanced materials for engineering.
Scientists have shown that soccer players with superior ability in areas such as passing accuracy or sprint speed do not necessarily achieve better overall performance on the pitch.
Gwendolyn David, PhD researcher at the University of Queensland, says "Athletic abilities measured in the lab were not associated with any measure of performance on the pitch. In other words, it's not your ability, it's what you do with it that counts."
Zooplankton can use specialised adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low almost nothing can survive - but they may run into trouble as these areas expand under climate change.
In this month's special issue of Physics World, which examines the science and applications of invisibility, Martin McCall and Paul Kinsler of Imperial College London describe a new type of invisibility cloak that does not just hide objects – but events.
Using the ultimate bank heist as an example, McCall and Kinsler explain how a thief could, in principle, use an "event cloak" to steal money from a safe, without even the CCTV surveillance cameras being aware.
Researchers have been investigating the connection between fifth century Himalayan instruments used in religious ceremonies and modern physics.
In a study published today, 1 July 2011, in IOP Publishing's journal Nonlinearity, researchers have captured high speed images of the dynamics of fluid-filled Tibetan bowls and quantified how droplets are propelled from the water's surface as the bowls are excited.
"Goat plague," or peste des petits ruminants (PPR), is threatening global food security and poverty alleviation in the developing world, say leading veterinarians and animal health experts in this week's Veterinary Record.
They call on the UN Food and Agricultural Organisation (FAO) and the World Organisation for Animal Health (OIE) to turn their attention now to ridding the world of the PPR virus, which carries a very high risk of death among infected animals.
The first scientific results from an ambitious voyage led by a group of graduate students from Scripps Institution of Oceanography at UC San Diego offer a stark view of human pollution and its infiltration of an area of the ocean that has been labeled as the "Great Pacific Garbage Patch."
