Nuclear power is sometimes described as being free of greenhouse gas emissions, and that’s true of the nuclear fission reactions themselves. But here is a list of all the stages of the nuclear power cycle at which greenhouse gases are emitted: uranium mining, uranium milling, conversion of uranium ore to uranium hexafluoride, uranium enrichment, fuel fabrication, reactor construction, reactor decommissioning, fuel reprocessing, nuclear waste disposal, mine site rehabilitation, and transport throughout all stages.

The European Union has released some data on the latest call for applications for ITN grants. These are "training networks" where academic and non-academic institutions pool up to provide innovative training to doctoral students, in the meanting producing excellent research outputs.

A detailed analysis of the remains of a high-status Danish Bronze Age female, known as the Egtved Girl, has revealed information about her movements, what she ate, and where her clothes came from.

The Egtved Girl, a 16–18 year old female, was discovered in the Danish village of Egtved in an oak coffin, calculated to have been buried around 3,400 years ago.

 A new class of magnets that swell in volume when placed in a magnetic field also generate negligible amounts of wasteful heat during energy harvesting.

This "Non-Joulian Magnetostriction" could change the way we think about a certain type of magnetism that has been in place since 1841, when physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field. This phenomenon is referred to as "Joule Magnetostriction," and since its discovery 175 years ago, all magnets have been characterized on this basis.

In 2003, while French youth protested American imperialism, 14,000 mostly elderly people were allowed to die in a heat wave. Heat waves kill a lot more people, it is believed, except they don't. Instead, an analysis of  74 million deaths in 384 locations across Australia, Brazil, Canada, China, Italy, Japan, South Korea, Spain, Sweden, Taiwan, Thailand, UK, and the USA found that cold weather kills about 20 times as many people as hot weather.

Scientists have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered.

The tools, whose makers may or may not have been some sort of human ancestor, push the known date of such tools back by 700,000 years and may challenge the notion that our own most direct ancestors were the first to create new technology.

The discovery is the first evidence that an even earlier group of proto-humans may have had the thinking abilities needed to figure out how to make sharp-edged tools. The stone tools mark "a new beginning to the known archaeological record," say the authors of a new paper about the discovery. 

Researchers have confirmed strong warming in the upper troposphere, known colloquially as the tropospheric hotspot, long expected as part of the global warming hypothesis. 

Though the tropospheric hotspot appears in many global climate models, the inability to detect it has been used to suggest climate change is not occurring as a result of increasing carbon dioxide emissions. 

Some Americans may regard the half of U.S. science that works in academia as overtly partisan due to a lack of political diversity, but it doesn't affect science issues. Though the anti-vaccine, anti-GMO and anti-energy movements are overwhelmingly populated by the left, scientists readily attack those positions because evidence matters most to American scientists.

Not so much in Europe. American academia may have a political litmus test for getting a faculty job but that doesn't bleed over into science research. In much of Europe you are more likely to need to check off all of the correct cultural boxes to get a job in the first place. And you had better not deviate from the plan.

If you think of your 'sense of self', do you locate it in your heart or your brain? 

It can tell people a lot about your decision-making process. Obviously, advertising is one area.  Messages targeted at people with independent self-construals (your head tells you buying this car is the right decision because it has good value) will work better for those people than messages targeted at people with interdependent self-construals (Your heart tells you buying this car is the right decision because it has the highest safety ratings for families.) 

Our belief in evil influences our feelings about capital punishment, according to Donald Saucier, associate professor of psychology at Kansas State University and Russell Webster at St. Mary's College of Maryland.

They drew their conclusion after about 200 participants were given a summary of a case in which a murderer confessed to his crime. They then asked each participant about his or her support for different types of sentences, such as jail time with community service, jail time with the opportunity for parole, jail time without the possibility for parole and other options.
