Do you support unions, a minimum wage, dislike business and hate child labor and then tell all of your friends on your iPhone?

People rationalize moral standards when it comes to their own lives, say economists writing in Science. It's easy to lament child labor and exploitation of the work force but if you are not willing to pay $2,000 for a phone, you are part of the problem and Tweeting about social issues on that phone helps precisely no one but corporate shareholders.

'Pestilence', widespread outbreaks of deadly contagious disease, are known throughout history. In popular translations of the Christian Bible, Pestilence is one of the Four Horsemen of the Apocalypse.

Today we call them pandemics but they are nothing like plagues of old, when up to 33% of a population was eradicated, like during the Black Death of the 14th century.

Using advanced underwater imaging techniques, one of the most detailed analysis ever of the archaeological remains of the lost medieval town of Dunwich - 'Britain's Atlantis' - have been revealed.

The Carmona necropolis in Spain is a collection of funeral structures built between 200 B.C. and 200 A.D. One of them is known as the Elephant's Tomb because a statue in the shape of an elephant was found in the interior of the structure.

Despite the wide use of sentences beginning with a word ending in -ly  and despite the acceptance of such usage by people who know how language is used in the real world: despite these facts there are still some people who throw up their hands in horror at such "abuse" of language.  Having been taught no doubt by repeaters of that Latin-based snobbery which was once peddled as English grammar, such people insist that -ly words are adverbs and as such they must, must, must - on pain of death - modify a verb.  "Where is the verb?", they cry.  That is woo of the first water.

We all know about people’s personalities, and anyone with a dog or a cat will also tell you about their temperaments. More surprising, though, is how many others, from octopuses to frogs and even spiders have them. So why behave according to a personality, when flexibility could allow smarter choices?

Cirrus clouds, the thin wisps of vapor that coalesce in the upper layers of the troposphere and trail across the sky, often more than 10 miles above the Earth's surface, influence our global climate, cooling the planet by reflecting incoming solar radiation and warming it by trapping outgoing heat.

Understanding the mechanisms by which these clouds form would help scientists make accurate predictions about future climate patterns.

Water found on the moon and Earth came from small meteorites called carbonaceous chondrites in the first 100 million years or so after the solar system formed, according to researchers who found evidence in samples of moon dust returned by lunar crews of Apollo 15 and 17.

Comets did not deliver the molecules, they conclude in their Science Express article.

The discovery's telltale sign is found in the ratio of an isotopic form of hydrogen, deuterium, to standard hydrogen. The ratio in the Earth's water and in water from specks of volcanic glass trapped in crystals within moon dust match the ratio found in the chondrites. The proportions are far different from those in comet water. 

In a previous article, I demonstrate how to build an alcohol burner for a home chemistry set. In my article, I mention that "second-hand stores like Goodwill, Salvation Army, and local mom&pop shops are treasure troves of things to hack or repurpose."

I would like to mention too that close-out stores like Dollar General are also fertile ground for modding.

While school-age models of atomic nuclei show them as being spherical, like a basketball, they are more like the shape of a football. 

Yet for some particular combinations of protons and neutrons, nuclei can also assume very asymmetric shapes, like a pear, where there is more mass at one end of the nucleus than the other.
