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

Perhaps it was too good to be true. Two months ago, a team of cosmologists reported that it had spotted the first direct evidence that the newborn universe underwent a mind-boggling exponential growth spurt known as inflation. But last week a new analysis suggested the signal, a subtle pattern in the afterglow of the big bang, or cosmic microwave background (CMB), could be an artifact produced by dust within our own galaxy. "We're certainly not retracting our result," says John Kovac, a cosmologist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, and co-leader of the team, which used a specialized telescope at the South Pole known as BICEP2. Others say the BICEP team has already lost its case. "At this time, I think the fair thing to say is that you cannot claim detection-period," says Paul Steinhardt, a theoretical physicist at Princeton University. From 2010 through 2012, BICEP2 peered at a small patch of the CMB to measure the polarization of the microwaves as it varies from point to point. On 17 March, BICEP researchers announced at a press conference in Cambridge that they had spotted ultrafaint pinwheel-like swirls in the sky. Those swirls, or B modes, are most likely traces of gravitational waves rippling through space and time during the 10-32 seconds that inflation lasted, the BICEP team says, and they fulfill a key prediction of the theory of inflation. Many cosmologists hailed the detection as a smoking gun for that theory.
