Geothermal energy is increasingly contributing to the power supply where it is affordable and efficient. Iceland is world-leader in expanding development of geothermal utilization: in recent years the annual power supply there doubled to more than 500 MW in the supply of electricity.  Even in Germany, over 100 MW of heat are currently being provided through geothermal energy.  

We hear a lot from various advocacy groups that modern lifestyle is the worst thing that can happen to us.    Indeed, some won't be happy until we get back to the sustainable, renewable period of 1300AD.   But modern lifestyle has at least one friend; our teeth. 

A review of studies published in a Supplement to Obesity Review examined evidence over the past 150 years and says that the effects of fluoride toothpaste, good oral hygiene and health education has overriden the effects of food on tooth decay.

The American Institute of Physics (AIP) announced the winners of its 2008 Science Writing Awards today. The winners -- two scientists, a journalist, a children's book author, and a public television producer -- will receive four prizes of $3,000, engraved Windsor chairs, and certificates of recognition.

"These outstanding science communicators have each improved the general public's appreciation of physics, astronomy, and related sciences through their wonderfully creative endeavors," says Catherine O'Riordan, AIP Vice President, Physics Resources.

Unique fractures in lavas on ancient Mars suggest water occasionally flooded portions of the planet's surface.   The fractures, known as "columnar joints," are the first that have been observed on a planet other than Earth. 

The characteristics of the column-like fractures can help scientists understand the role of water in geologic processes on Mars, said Moses Milazzo, a geophysicist with the U. S. Geological Survey Astrogeology Team in Flagstaff and lead author on a paper on the discovery recently published in the journal Geology.

"Columnar joints form as cooling lava contracts," said Milazzo.

Chiltern a leading global clinical research organization announced today that it has appointed Ms. Jane Turner to the post of Director, Late Phase, Europe.

To the historian, English is a fascinating language.  Unlike most of the languages of Europe, it underwent an almost complete makeover following the Norman invasion (1066 and All That).  As a result, although or basic words and grammar are basically like German and especially Dutch, the lion’s share of our vocabulary is from French and Latin.  

My grandfather had a special room in his cellar for the various presses and casks he used to make his notoriously mouth-wrenching red wine.  I have friends whose microbrew apparatus takes up the entire spare bedroom of their house, like a permanently boozy-smelling houseguest.  Accordingly, I thought that fermenting was best left to the hardcore hobbyists-- too complicated a pursuit for the average partly-stocked kitchen.  Turns out, it's pretty simple. I recently made ginger ale with only items I had laying around my kitchen.
