When saying 'please' is more strategic than magic

By kindergarten age, most children have been taught that 'please' is a magic word. 'Please' is an expression of politeness that shows courtesy and respect, turning a potential demand into a request that will -- poof! -- magically be granted. But a new study on the ways people make requests of one another suggests that 'please' might not be an all-purpose marker of politeness, but rather a more focused, strategic tool to manage frictions or obstacles among family members, friends and even coworkers. The study shows that people say 'please' much less often than expected, and mostly when they expect a 'no' response is forthcoming.

The case for sharing carbon storage risk

Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.

Counterfeit coins can be detected more easily thanks to a novel approach

Researchers present a novel framework that uses image-mining techniques and machine learning algorithms to identify flaws in counterfeit coins. The researchers' framework uses fuzzy association rules mining to find patterns that are similar but 'fuzzy,' i.e., not clear enough to be exact copies. However, the framework will eventually arrive at a certain range of results where positive matches be confidently extract frequent patterns from the images. These patterns capture relationships among the blobs' attributes, such as color, texture, shape and size. The patterns help researchers to better understand the images and tell whether a coin is real or fake.

The price tag of phasing-out coal

Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, but it excludes China and India, the two largest users of coal that currently do not have phase-out plans. The study shows that if China and India decide to phase out coal as fast as needed to reach the Paris climate targets and pay similar compensation, it would cost upwards of USD 2 trillion.
