Where climate change is most likely to induce food violence

While climate change is expected to lead to more violence related to food scarcity, new research suggests that the strength of a country’s government plays a vital role in preventing uprisings.

“A capable government is even more important to keeping the peace than good weather,” said Bear Braumoeller, co-author of the study and associate professor of political science at The Ohio State University.

NASA Looks at Extreme Florida Rainfall by Satellite

Extremely heavy rain has recently fallen over Florida and the Global Precipitation Measurement or GPM mission core satellite looked at that some of that rainfall on June 7. Rainfall records were broken on that date as the GPM satellite passed overhead from space.

Over 19 inches (482 mm) of rain had fallen in southeastern Florida during the past seven days beginning June 1. Record rainfall has been reported in Fort Lauderdale and West Palm. This extreme rainfall has led to flooding and flight cancellations.

Novel material removes pollutant PFOA to levels far below EPA's health advisory limit

A highly toxic water pollutant, known as perfluorooctanoic acid (PFOA), last year caused a number of U.S. communities to close their drinking water supplies. Because of its historical use in Teflon production and other industrial processes as well as its environmental persistence, PFOA contamination is a pervasive problem worldwide.

Sydney Harbour emissions equivalent to 200 cars on the road

The Sydney Harbour is renowned as a beautiful landmark straddling our thriving city  but a new study has shown it is also a source of significant carbon emissions, which requires careful management as the city is poised to double its population by the end of the century.

That is the message of new research that has quantified CO2 emissions from the Harbour for the first time – found to be 1000 tonnes annually – equivalent to the pollution from about 200 cars.

Griffith scientists engineer new cancer detection tool

Studying the food poisoning bacteria E. coli may have led scientists to discover a new and improved tool to detect cancer.

In a collaborative research project, scientists from Griffith University’s Institute for Glycomics, the University of Adelaide and University of Queensland have detailed their findings in a new paper published in Scientific Reports.

Monkey See, Monkey Do, Depending on Age, Experience and Efficiency

Wild capuchin monkeys readily learn skills from each other — but that social learning is driven home by the payoff of learning a useful new skill. It’s the first demonstration of “payoff bias” learning in a wild animal, and could inform whether and how animals can adapt to rapidly changing conditions, for example due to climate change or reintroduction of species from captive breeding.  

Record 'green' energy capacity added in 2016 as cost for renewables plunges – UN-backed report

The world is now adding more green energy capacity each year than it adds in new capacity from all fossil fuels combined, a United Nations-backed report revealed today, showing that the “renewables train has already left the station” and those who ignore this will be left behind.

Small climb in mean temperatures linked to far higher chance of deadly heat waves

An increase in mean temperature of 0.5 degrees Celsius over half a century may not seem all that serious, but it’s enough to have more than doubled the probability of a heat wave killing in excess of 100 people in India, according to researchers at the University of California, Irvine and other institutions.

ALMA Finds Ingredient of Life Around Infant Sun-like Stars

Two teams of astronomers have harnessed the power of the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to detect the prebiotic complex organic molecule methyl isocyanate [1] in the multiple star system IRAS 16293-2422. One team was co-led by Rafael Martín-Doménech at the Centro de Astrobiología in Madrid, Spain, and Víctor M. Rivilla, at the INAF-Osservatorio Astrofisico di Arcetri in Florence, Italy; and the other by Niels Ligterink at the Leiden Observatory in the Netherlands and Audrey Coutens at University College London, United Kingdom.

Increased Sea Ice Drift Puts Polar Bears on Faster Moving Treadmill

A new study led by the U.S. Geological Survey and the University of Wyoming found that increased westward ice drift in the Beaufort and Chukchi seas requires polar bears to expend more energy walking eastward on a faster moving “treadmill” of sea ice.  

These findings represent the first assessment of the consequences of changing drift rates for polar bears; one of several previously unexplored effects of sea ice loss.
