Most people think of aerosols as something you’d get from a spray can but scientists are discovering more about how these atmospheric particles are protecting the planet.
Research led by Griffith University and the Bigelow Laboratory for Ocean Sciences in the USA, recently published by the American Meteorological Society, has revealed the role marine biogenic aerosols play in the Arctic and Southern oceans, helping the global challenge climate scientists face – understanding aerosol effects on warming.
Most aerosols have a cooling influence on the climate by reflecting sunlight back into space and altering cloud microphysics. Without their ‘masking’ effects, global temperatures would have increased more than they have since the 18th century.
Until recently aerosols have been acting like a ‘handbrake’ on global warming but Associate Professor Albert Gabric, of the Griffith School of Environment, warns the possible decline in emissions of natural and anthropogenic aerosols in the future could accelerate the warming

Body art as branded labour
Would you employ someone with a visible tattoo?
If you’re wanting to target a younger, trendier demographic – it might be worth considering.
Associate Professor Andrew Timming, of the University of Western Australia, recently visited Griffith University’s Centre for Work, Organisation and Wellbeing.
His research centres around physical appearance and its relationship to success – or otherwise – in the workplace.
Associate Professor Andrew Timming of the University of WA.
Assoc Prof Timming’s most recent work looked at visible body art, traditionally considered an impediment to employability.
“People with tattoos are often at the receiving end of unfounded prejudices,” he said.
“I wanted to research the positive effects of body art in the labour market because no one should be stereotyped.”
He acknowledged that times are changing but said tattoos are often still perceived, especially by older generations, as indicators of criminality, deviance, untrustworthiness and mental ill health.
To complete his research, he surveyed almost 200 respondents with management experience
Concerns rise over potential adverse health effects of 5G technology
Concern over the potential long-term adverse health effects associated with new 5G mobile phone technology will be the focus of a public lecture today (Thursday August 17) at Griffith University.
“The health effect issue of 5G is potentially very controversial as the communications industry is massive and 5G technology will be quite pervasive but its long-term health effects on humans are largely unknown,” says Professor Dariusz Leszczynski, the keynote speaker at the public lecture co-hosted by Griffith’s Centre for Environment and Population Health and the Australian Institute of Occupational Hygienists.
Professor Leszczynski was one of the thirty experts on the International Agency for Research on Cancer (IARC)/WHO 2011 evaluation group that classified all radio frequency (RF-EMF) emissions as a possible carcinogen.
Current safety limits could be insufficient
Professor Leszczynski suggests that the current safety limits imposed on wireless communication devices (WCD) are insufficient to protect all users of such devices. “Besides carcinogenicity, there are
Research sheds light on renewables & stock market
If you want strong stock market growth, invest in renewable energy.
Research from Griffith University and Jiangxi University, described as “the exact opposite of what we’ve been lead to believe”, shows there’s a positive correlation between renewables and the market – a potential boon for the economy as a whole.
The paper, called ‘The effects of stock market growth and renewable energy use on CO2 emissions’, was published in Energy Economics.
Dr Rakesh Gupta
Dr Rakesh Gupta from Griffith Business School said he was sceptical when the idea was first floated but “shocked” at the final results.
“We tested our findings and analysed different models to ensure it was, indeed, true.”
Dr Gupta said the implications for emerging economies were also significant, as it could potentially lead to more foreign direct investment.
“There’s a whole perception out there that investment in renewable energy hurts the economy and takes away jobs – but that’s simply not true.”

Three minute thesis competition heats up
Arts, Education and Law (AEL) contestants in the Three Minute Thesis Competition have gone head-to-head in the Group round, with three out of ten contestants now progressing through to the Griffith final to be held in early September.
AEL students have performed strongly at the University level round, having won the university competition for the past 3 years in a row.
Queensland Conservatorium doctoral candidate, Julia Nilon took out first place in the AEL heat and the $350 prize, with her presentation on the role musical theatre repertoire plays in child vocal and singing development.
Second place was a draw between Queensland College of Art doctoral candidate Rae Cooper, who presented on whether Protest Design is an effective mechanism of democratic influence, and Queensland Conservatorium doctoral candidate Nathaniel Smorti, who shared his research into clarinet interpretation.
Both second place winners received a $250 prize.
Queensland Conservatorium Honours candidate Elliott Plumpton also competed, taking out the
Griffith researchers make inroads into fighting malaria
Griffith University scientists have helped discover new compounds which could help block the transmission of the deadly disease malaria.
A team of Griffith researchers has found a novel class of compounds, the hexahydro quinoline (HHQ), with potent activity against the parasite stages responsible for the clinical symptoms of malaria and its transmission to mosquitoes.
Malaria is still a leading cause of death, with 212 million new cases and 429 000 malaria deaths recorded worldwide in 2015, 90% of which are in Africa. A major obstacle in eradicating the disease is wiping out the sexual forms of the malaria parasites, the gametocytes.
While not responsible for the clinical symptoms, gametocytes are essential for the continued transmission of malaria, as these are the parasite stages taken up by the mosquito.
Gametocytes are naturally insensitive to the antimalarial drugs routinely used for malaria therapy and therefore escape the killing action of the drugs, enabling the new infections
Pilot Dan takes aviation degree sky high
From his office 10,000m above the ground, Virgin Australia pilot Dan Lang surveys a career that is literally and figuratively flying.
Becoming a pilot was Dan’s dream from boyhood when he and his family made the long-haul flights from Australia to visit loved ones across the world.
The journey from enthusiastic youngster to an aviation degree from Griffith University and now to a commercial flying career has taken years of dedication and diverse experience. And there are still a few more air miles to log as Dan prepares to transfer from the co-pilot’s seat on the right of the Virgin cockpit to the captain’s seat on the left.
Dan’s family emigrated from Switzerland to Sydney in 1988 and international flights became a part of life.
“I loved flying from the start and that has never changed,” says Dan, 34, who is based in South East Queensland where he lives with dietitian wife Michelle and their
