Though the Intergovernmental Panel on Climate Change (IPCC) has asked science journalists and political writers wearing a scientific beard to not attribute every weather event to climate change, it is still common to have every storm, drought and temperature to be listed as proof of climate change.But that isn't science.  Scientists at the California Institute of Technology (Caltech) and ETH Zurich have instead shown that global warming actually tends to reduce temperature variability.

Compared to most languages in the developed world, Icelandic is quite conservative. Formal German is almost useless in actual German society due to slang and informal terms, for example, while English has few rules but so many exceptions and colloquial phrases it can be difficult for tourists to understand eating in a restaurant.Icelandic, by contrast, has a vocabulary well preserved in Old Norse roots and Icelanders want to keep it that way.  The purist tradition of preferring native words to foreign ones is thought to be connected to Iceland’s long process of liberation from Denmark, which was noticeable in the Icelandic language from the second half of the 19th century to some decades after the final independence in 1944.

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.

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.

Urine is commonly believed to be sterile until it reaches the urethra but that has led to numerous misconceptions about what can and should or should not be done with it. Drinking urine is a bad idea, for example, because even though it is sterile it contains urea and other substances
that can still be toxic.

A new study finds that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments may ramp up production. Though methane stays in the atmosphere for far less time than CO2, it is 25X more potent during that period. Concerns about methane have risen because of concerns about possible leaks due to increased natural gas, which produces far less CO2 than coal, and that methane may be released as climate changes.
