China’s troubled Jade Rabbit lunar rover has died on the surface of the moon, in a major setback for Beijing’s ambitious space program.
The country’s first moon rover “could not be restored to full function”, the state-owned China News Service said in a brief report, after the landmark mission ran into mechanical problems last month.
The Jade Rabbit, or Yutu in Chinese, was deployed on the moon’s surface on December 15 and was a huge source of pride in China – only the third country to complete a lunar rover mission after the United States and the former Soviet Union.
The landing was a key step forward in Beijing’s ambitious military-run space program, which include plans for a permanent orbiting station by 2020 and eventually sending a human to the moon.
The rover experienced a “mechanical control abnormality” in late January due to “the complicated lunar surface environment”, according to the official Xinhua news agency, and was unable to function since then :: Read the full article »»»»

Australians are getting more obese by the day, with experts warning body fat is masking the diagnosis of other illnesses. It is causing stress on Australia’s public health system and the people who have to examine the grossly overweight bodies. South Australian forensic pathologist Roger Byard says the problem is so bad he cannot get some of his clients onto his examination tables, reports Rebecca Brice from abc.net.au.
Dr Byard says obesity is one of the most frightening epidemics he has seen in his four decades in medicine. “We have antibiotics for infections, we have chemotherapy for cancer, so we take two steps forward but with the obesity problem we’re almost taking three steps back,” Dr Byard said.
Dr Byard says since 1986 the rate of morbidly obese bodies entering his Adelaide mortuary has risen from just over 1 per cent to almost 5 per cent. At times the bodies are so big he has to dissect them on the floor. “We try to avoid this obviously, but if a body is so large that we can’t safely put the body on a trolley then we have to perform the autopsy on the floor, which is terribly difficult.”
The bigger the bodies, he says, the harder it is to dissect them and the harder it is to find the cause of death. “Obesity comes with so many diseases – it’s almost how do you choose which is the problem,” he said. “As well as the fact that they have to carry this excess weight around, their heart’s being compressed and this adipose tissue material is secreting toxins that people think actually cause death of heart cells. So they’re being attacked on all fronts.” Dr Byard said.
The problems are not confined to the morgue. Some obese hospital patients do not fit into CT scanning machines and excess fat can hinder the taking of blood using syringes, which impedes diagnosis in both the dead and the living.

The Doomsday clock ( Wiki Below) has ticked another minute closer to midnight on the back of global uncertainty on how to deal with the threats of nuclear weapons and climate change.
“It is now five minutes to midnight,” said Allison Macfarlane, chair of the Bulletin of Atomic Scientists (BAS), which created the clock in 1947 as a barometer of how close the world is to an apocalyptic end.
The last decision by the group, which includes a host of Nobel Prize-winning scientists, moved the clock a minute further away from midnight in 2010 on hopes of global nuclear cooperation and the election of US president Barack Obama. However, the latest decision pushes the clock back to the time it was at in 2007.
Increasing nuclear tensions, refusal to engage in global action on climate change, and a growing tendency to reject science when it comes to major world concerns were cited as key reasons for the latest tick on the clock.
“It is clear the change that appeared to be happening at the time is not happening, not materialising,” co-chair Lawrence Krauss said. “Faced today with the clear and present dangers of nuclear proliferation, climate change, and the continued challenge to find new and sustainable and safe sources of energy, business as usual reigns the norm among world leaders.” Read the full article »»»»

To the untrained eye, fungus, mushroom and the like are all pretty much a muchness. To South Australian botanists, however, it occupies a much more esteemed position, becoming the one millionth specimen to be collected by the State Herbarium.
This small gilled fungus – botanical name Entolama parasiticum – was found growing on damp and rotten wood on Kangaroo Island and may in fact be a new species. The wood is likely to have fallen during the 2007 bushfire on the island and was collected by researchers Pam Catcheside, Helen Vonow and David Catcheside. Read the full article »»»»

A large metallic ball has fallen out of the sky on a remote grassland in Namibia, prompting baffled authorities to contact NASA and the European space agency. The hollow ball with a circumference of 3.5 feet/1.1 metres was found near a village in the north of the country some 465 miles/750 kilometres from the capital Windhoek, according to police forensics director Paul Ludik. Locals had heard several small explosions a few days beforehand, he said. With a diameter of 35 centimetres, the ball has a rough surface and appears to consist of “two halves welded together”. It was made of a “metal alloy known to man” and weighed six kilograms, Mr Ludik said. The ball was found 18 metres from its landing spot, a hole 33 centimetres deep and 3.8 metres wide. Several such balls have dropped in southern Africa, Australia and Latin America in the past 20 years. The ball is likely to be a “composite overwrapped pressure vessel”, used by NASA to store gases under pressure in space.
The strength needed to maintain pressure within the balls means they are manufactured from tough material including Kevlar, and therefore likely to remain intact when they re-enter the earth’s atmosphere. The sphere was discovered in mid-November, but authorities first did tests before announcing the find.
