Want to get in a fight in Scotland?

Okay, just about anything will get you into a fight in Scotland but if you want a guaranteed way to get a headbutt and then kicked when you are on the ground, tell them they did not invent golf, the world's most frustrating pastime.

A contaminated river and a polluted sky are proof that environmentalism isn't just for the rich any more, say sociologists.

Obviously it never was, in many countries.  In the developed world, people in the country actually care more about the environment than rich urbanites, but in the developing world the practical takes precedence over policy.  The poor can't afford to protect the environment.

A new survey says that may be true in the country but in the city it is another matter. People living in China's cities who say they've been exposed to environmental harm are more likely to be green, recycling or reusing grocery bag.  It also says the poor would sacrifice economic gain to protect their environment.

With the Supreme Court decision to uphold mandatory health insurance purchasing under the Affordable Care Act, it's going to get more expensive. But for thousands of years people were able to go into the woods and get health care for free, so all is not lost. Maybe they can even get a rebate for using nature.

Natural remedies may not be as effective as their synthetic pharmacological cousins but a Harvard post-doc says there may be economic benefits people could receive by relying on such traditional cures.  If that feels like 'ketchup is a vegetable' sweet lemons rationalization, you are not alone.

The brain is like a muscle; it can get into a routine.  But mixing up the workout a little is healthy in both cases.  In the brain, however, it isn't without difficulties.

Learning a new task when rules change can be a surprisingly difficult process and entail repeated mistakes, according to a new study. Take a US driver and put them in England where they suddenly have to drive on the left side of the road. The brain, trained for right-side driving, becomes overburdened trying to suppress the old rules while simultaneously focusing on the new rules  - putting them on a moped if they are used to driving a car would make it even worse.

A  giant human sculpture has been unearthed at the Tayinat Archaeological Project excavation site in southeastern Turkey.

The head and torso of the human figure is intact to just above its waist and stands approximately 5 feet tall, so it likely had a total body length of 10 to 12 feet. The figure's face is bearded, with beautifully preserved inlaid eyes made of white and black stone, and its hair has been coiffed in an elaborate series of curls aligned in linear rows. Both arms are extended forward from the elbow, each with two arm bracelets decorated with lion heads. The figure's right hand holds a spear, and in its left is a shaft of wheat. A crescent-shaped pectoral adorns its chest.

The latest issue of Philosophy Now features an interesting collection of articles on human enhancement, with articles arguing that the approach is “essential” to humans in order to avoid catastrophes, that it can be used to extend youthfulness, and so on. There are also a couple of essays that are more cautious about the likely success, and even perils, of enhancement, so the full package (five entries) makes for stimulating reading.

Researchers have created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. 

Chirality is the distinct left/right orientation or “handedness” of some types of molecules, meaning the molecule can take one of two mirror image forms. The right-handed and left-handed forms of such molecule are called “enantiomers” and can exhibit strikingly different properties. One enantiomer of the chiral molecule limonene smells of lemon, the other smells of orange. The ability to observe or even switch the chirality of molecules using terahertz (trillion-cycles-per-second) electromagnetic radiation is a much coveted asset in the world of high technology.
