Put the lime in the ocean... - Some scientists believe that adding lime to seawater may increase the ocean's ability to absorb CO2 without increasing it's acidity. An investigation may soon be underway to test the theory.
Mars may have been all wet - New observations by the Mars Reconnaissance Orbiter seems to indicate that major parts of the landscape were altered by water, providing evidence of a past in which Mars was covered by a significant amount of water.
Needles without pain - Japanese and Indian scientists have built a microneedle based on the way a female mosquito sucks blood. The needle has a diameter of 60 microns compared with the 900 microns of contemporary needles. It uses a microelectromechanical pump that also reproduces the sucking action of the mosquito, resulting in a method for extracting small quantities of blood that is essentially painless.
