Wealthy nations willing to collectively spend about $1 billion annually could prevent the emission of roughly half a billion metric tons of carbon dioxide per year for the next 25 years, says a new study. It would take about that much money to put an end to a tenth of the tropical deforestation in the world, which would lead to lower greenhouse gas emissions, they say, and reduce global carbon emissions by between 2 and 10 percent.

The calculation is one of several estimates described by a team of scientists and economists this week in the online edition of Proceedings of the National Academy of Sciences. The calculations, based on three different forestry and land-use models, provide the best estimates so far of how much it would cost developed nations to participate in a program called "avoided deforestation" to reduce worldwide carbon emissions.

A report by scientists from The Netherlands published in The FASEB Journal identifies a compound in human saliva that greatly speeds wound healing. This research may offer hope to people suffering from chronic wounds related to diabetes and other disorders, as well as traumatic injuries and burns.

In addition, because the compounds can be mass produced, they have the potential to become as common as antibiotic creams and rubbing alcohol.

Specifically, scientists found that histatin, a small protein in saliva previously only believed to kill bacteria was responsible for the healing.

Mark Mulac was once an avid lover of iced tea, downing up to six glasses a day. Unfortunately, he was forced to go cold turkey. Iced tea helped to bring on an excruciating bout of kidney stones that led to surgery at Loyola University Hospital in Maywood, Ill.

Iced tea contains high concentrations of oxalate, one of the key chemicals that lead to the formation of kidney stones, a common disorder of the urinary tract that affects about 10 percent of the population in the United States.

Kidney stones are crystals that form in the kidneys or ureters, the small tubes that drain the urine from the kidney to the bladder. Men are four times more likely to develop kidney stones than women, and their risk rises dramatically once they reach their 40s.

This DelFly Micro, made by Delft University of Technology, is a 'Micro Air Vehicle' (MAV), an exceptionally small remote-controlled aircraft with camera and image recognition software. The Micro, weighing just 3 grams and measuring 10 centimeters (wingtip to wingtip) has a minuscule battery weighing just 1 gram, can fly for approximately three minutes and has a maximum speed of 5 meters per second.

This kind of ultra-small, remote-controlled, camera-equipped aircraft is of great interest because they could eventually be used for observation flights in difficult-to-reach or dangerous areas.
