Australia’s CSIRO has come up with some pretty amazing inventions over the past 86 years of research, from polymer banknotes to insect repellent and the world-changing Wi-Fi. But we can also lay claim to something a little more esoteric – we actually invented a whole new word.

It is well established that particles emitted during major volcanic eruptions cool the atmosphere for two or three years  due to a 'parasol' effect that reflects sunlight.

Plagiarism is the most sincere form of flattery, they say (or rather, this is said of imitation). In arts - literature, music, painting - it can at times be tolerated, as an artist might want to take inspiration from others, elaborate on an idea, or give it a different twist. In art it is the realization of the idea which matters.

A new study has recommended against using nitrogen to fertilize radiata pine plantations after analysis of more than 1,500 soil samples gathered in timber woodlands in Bizkaia and the north of Araba-Álava in recent years.  Fertilizing using phosphorus is recommended in virtually the whole area in the study as it may be helpful in obtaining better yields on radiata pine plantations.  

Cholesterol-lowering statins have transformed the treatment of heart disease. But while the decision to use the drugs in patients with a history of heart attacks and strokes is mostly clear-cut, that choice can be a far trickier proposition for the tens of millions of Americans with high cholesterol but no overt disease.

Now a report from preventive cardiologists at Johns Hopkins and elsewhere offers a set of useful tips for physicians to help their patients make the right call.

The report, published March 30 in the Journal of the American College of Cardiology, combines the experts' collective clinical wisdom with previously published research on the benefits and potential downsides to long-term statin use.

A new paper creates a link between exposure to pesticide residues from fruits and vegetables and semen quality. 

Men who ate fruits and vegetables with higher levels of pesticide residues, like strawberries, spinach, and peppers, had lower sperm count and a lower percentage of normal sperm than those who ate produce with lower residue levels, according to the new paper.

Researchers have tested a range of neuroprosthetic devices, from wheelchairs to robots to advanced limbs, that work with their users to intelligently perform tasks.

They work by decoding brain signals to determine the actions their users want to take, and then use advanced robotics to do the work of the spinal cord in orchestrating the movements. The use of shared control - new to neuroprostheses - "empowers users to perform complex tasks," says José del R. Millán, who presented the new work at the Cognitive Neuroscience Society (CNS) conference in San Francisco today.

In ancient times, attributing effects to the moon made some sense. If it could change tides, which everyone except Galileo recognized it did, why not cause effects in people? 

The UN Intergovernmental Panel on Climate Change (IPCC) is a group of climate change experts representatively selected from regions around the world that periodically releases Assessment Reports in order to inform policymakers and the public about the latest evidence for climate change. The publication of each report is a key event in the debate about climate change, but their reception and coverage in the media has varied widely.

A new paper has for the first time analyzed how Twitter, TV and newspapers reported the IPCC's climate evidence. Understanding how media coverage varies is important because people's knowledge and opinions on climate change are influenced by how the media reports on the issue.

Natural wetlands usually emit methane and sequester carbon dioxide. Anthropogenic interventions, in particular the conversion of wetlands for agriculture, result in a significant increase in CO2 emissions, which overcompensate potential decreases in methane emission. A large international research team now calculated that the conversion of arctic and boreal wetlands into agricultural land would result in an additional cumulative radiative forcing of about 0,1 MilliJoule (mJ) per square meter for the next 100 years.
