Decaf coffee gives same kick as full-strength
Decaffeinated coffee is no healthier than conventional coffee and may be just as likely to keep drinkers awake all night, scientists have found. Research in Switzerland shows that normal and decaffeinated coffee have near-identical effects on blood pressure and nervous activity, indicating that a decaf latte is no better for you than the real thing. The results suggest that coffee's well-established influence on blood pressure, nerve stimulation and cardiovascular health may have nothing to do with caffeine, contrary to received wisdom. Coffee has several hundred other chemical components, one or more of which must be responsible, the researchers from University Hospital in Zurich say.

Battered oil tanker breaks in two
A battered and leaking oil tanker damaged by a week of heavy seas off Spain broke in two at 0700 GMT on Tuesday. If all 77,000 tonnes that were originally on board the Prestige are lost, it will cause an ecological and fishing disaster along the coast of Portugal and Spain, say experts. The Exxon Valdez catastrophe, which struck Alaska in 1989, involved the loss of 41,000 tonnes of oil. (New Scientist)
Satellites to spot wildfire fallout
Satellites could soon monitor how much carbon dioxide, soot and other greenhouse gases and pollutants wildfires belch into the atmosphere. Experiments at King's College in London suggest infrared sensors on the latest Earth-observing satellites could be calibrated to measure the heat of a fire. From this researchers could infer how much carbon it is releasing. (Nature)
