Honoured researchers urge colleagues to fight anti-science Scientists need to fight against a growing anti-science sentiment worldwide by joining the debate, say two researchers acknowledged in today's Australia Day Honours. Professors Bruce McKellar and Sam Berkovic, both associated with the University of Melbourne, received the nation's highest honour when they were appointed Companions in the General Division of the Order of Australia. McKellar, a theoretical physicist, says the honour for his "eminent service to science, particularly the study of theoretical physics" came as a "surprise". However it highlights a remarkable journey from a NSW bush school playground to the hallways of Switzerland's Large Hadron Collider. "One of the things that is very nice about me getting this award is the fact I went to a bush school with 50 students and one teacher," he says. That one teacher at Budgeregong Public School near Forbes in NSW also happened to be his father. "In part it is to he that I owe my appreciation of mathematics and various forms of science," he says. Although officially retired, the 72-year-old will later this year become the first Australian and first southern hemisphere president of the International Union of Pure and Applied Physics. The prestigious position comes at a time when science - most notably climate and immunisation science - is under attack in western societies. "The basic denial is the denial that science has done anything for us," says McKellar. He cites the example of basic radio astronomy research to analyses radio signals from the universe that led to the development of mo

Info Mag Koyal Group Mars Rover Marks an Unexpected Anniversary With a Mysterious Discovery Ten years ago, NASA's Opportunity rover bounded to the surface of Mars for what was planned to be a three-month exploration. Opportunity is still going today - and still making discoveries. The latest, scientists said on Thursday at a news conference celebrating an anniversary none had expected 10 years ago, is a small rock that seemingly appeared out of nowhere. The rock, whose chemical composition was also unexpected, appears in an image taken Jan. 8. There was no rock in a picture taken of the same spot less than two weeks earlier. "This is strange," said Steven W. Squyres, the principal investigator for Opportunity, during the NASA news conference. But he added, "We don't think anything particularly exotic happened here." Dr. Squyres said the most likely explanation was that as the rover pirouetted at an uphill location, its lame right front wheel, which has not turned for years, dragged across the rock and flicked it out of the ground to its new location. The scientists have not yet spotted the divot where the rock popped out, but that spot may be obscured by the rover's solar panels. Year after year, Opportunity goes farther than anyone dreamed. The expectation had been that it would drive about a kilometer - six-tenths of a mile - before dust accumulated on the solar panels and the batteries drained. Unexpectedly, fortuitous winds periodically cleaned off the solar panels, and Opportunity, as well as its twin, Spirit, continued to operate. Spirit got stuck in a sand dune 2009 and then fell silent in 2010 after it was not able to point its solar panels toward the sun during the winter months.

U.S officials leading the fight against history's worst outbreak of Ebola have said they know the ways the virus is spread and how to stop it. They say that unless an air traveler from disease-ravaged West Africa has a fever of at least 101.5 degrees or other symptoms, co-passengers are not at risk. "At this point there is zero risk of transmission on the flight," Dr. Thomas Frieden, director of the federal Centers for Disease Control and Prevention, said after a Liberian man who flew through airports in Brussels and Washington was diagnosed with the disease last week in Dallas. Other public health officials have voiced similar assurances, saying Ebola is spread only through physical contact with a symptomatic individual or their bodily fluids. "Ebola is not transmitted by the air. It is not an airborne infection," said Dr. Edward Goodman of Texas Health Presbyterian Hospital in Dallas, where the Liberian patient remains in critical condition. Yet some scientists who have long studied Ebola say such assurances are premature - and they are concerned about what is not known about the strain now on the loose. It is an Ebola outbreak like none seen before, jumping from the bush to urban areas, giving the virus more opportunities to evolve as it passes through multiple human hosts.
