A dinosaur skeleton has sold at auction in the UK for nearly $AU720,000. The diplodocus skeleton, nicknamed Misty, is more than 150 million years old and 17 metres in length :: Read the full article »»»»
The World Solar Challenge has been won by the Dutch team in their superquick Nuna7, their solar powered car crossed the finish line more 100 kilometres ahead of closest rival Japan.
Hindmarsh Square was the scene of jubilant celebrations as the Dutch team, Nuon, cruised into the centre of Adelaide for the trophy presentation after completing the 3,000 kilometre road journey from the top ends capital, Darwin.
It marked the fifth win in the event for the team, who have now competed seven World Solar Challenges, the team will lead a victory parade through the streets of Adelaide on Sunday October 13.
The race was close right up until veteran Japanese team Tokai, lost its battle with cloudy skies closing in on the finish line, while Tokai was stuck on the side of the road with a flat battery, Nuon powered on passed to take line honours :: Read the full article »»»»
It may have all but been leaked, massaged and misquoted in the months prior to today’s release, however the United Nations’ Intergovernmental Panel on Climate Change – IPCC – report remains by far the most important climate report card on the planet.
More than 600 scientists contributed to the report, which is the result of almost seven years work by climate scientists and policy-makers. It’s based on more than 50,000 contributions from around the globe, and an exhaustive peer review process.
Long-term global temperatures are rising, Arctic ice is shrinking, permafrost melt is increasing, and sea levels are rising. The United Nations’ chief science panel also says it is 95 per cent certain that humans are behind the planet’s rising temperatures. According to the IPCC, the report is a conservative outlook.
While average land and sea temperatures will continue to rise, the report suggests the planet is heating at a slower rate than previously predicted. The worst case scenario is for a sea level rise by almost 1 metre, and temperatures could rise by around 2 degrees Celsius.
The IPCC panel says mankind needs a carbon budget if we are to restrict a rise in temperatures, the report predicts that since industrialisation we’ve emitted more than half a trillion tonnes of carbon dioxide, by 2040 we’ll have doubled those emissions :: Read the full article »»»»
It’s one of the most complex health issues facing the developed world in this 21st century, and it seems the harder we look into obesity, the more complex it becomes. Long gone is the simple ethos “food in = energy out.”
Researchers are battling to come to terms with what can only be described as an epidemic. A third of the world’s adult population is physically inactive, the couch-potato lifestyle kills about 5 million people every year, experts contributing to a special feature in the medical journal The Lancet say.
“Roughly three of every 10 individuals aged 15 years or older – about 1.5 billion people – do not reach present physical activity recommendations,” Dr Pedro Hallal and colleagues said in a report that described the problem as a pandemic.
Complicating an already complicated issue, a 2012 study by researchers at Georgetown University revealed how the mutation in a single gene can be responsible for the inability of neurons to effectively pass along appetite suppressing signals from the body to the right place in the brain.
Australian researchers have just undertaken one of the most comprehensive studies tracking the health of the nation. The findings paint a disturbing picture of the nation’s battle with diabetes and obesity. The AusDiab study was funded through a National Health and Medical Research Council grant and followed 11,000 Australians for 12 years :: Read the full article »»»»
NASA scientists reckon rock samples from Mars have shown that the dusty red planet would once have been capable of supporting life. Analysis of Mars rocks by the Curiosity Rover uncovered the building blocks of life – hydrogen, carbon and oxygen – and evidence the planet could once have supported organisms, NASA said.
“A fundamental question for this mission is whether Mars could have supported a habitable environment,” Michael Meyer, lead scientist for NASA’s Mars Exploration Program said. “From what we know now, the answer is yes.”
At a televised press conference, the NASA team said this was the first definitive proof a life-supporting environment had existed beyond Earth. Curiosity, a six-wheeled robot with 10 scientific instruments on board, is the most sophisticated vehicle ever sent to another planet.
The sample was drilled from sedimentary bedrock in an area which previous research had shown to be an ancient river system or lake bed. It was found to contain clay minerals, sulfate minerals and other chemicals :: Read the full article »»»»
