Hamlet algorithm answers the question: To buy, or not to buy?
Its a classic dilemma for air travelers in todays world of wildly varying ticket prices – should you purchase now if the rate seems reasonable, or wait for a better deal and take the risk that the price will go up?
Researchers at the University of Washington and the University of Southern California appear to have taken out some of the uncertainty with a new computer program tha
A team of Carnegie Mellon University and NASA scientists will travel to the Atacama Desert in northern Chile in April to conduct research that will help them develop and deploy a robot and instruments that may someday enable other robots to find life on Mars. The researchers will be using the Atacama, described as the most arid region on Earth, as a Martian analog.
The group is funded with a $3 million, three-year grant from NASA to the universitys Robotics Institute. They are collabo
Ammonia is a problem. All animal cells produce it, but how do they get rid of it? New research by Dr Dirk Weihrauch (University of Illinois at Chicago) to be presented on Wednesday 2 April (session A2.2) suggests that the crab may have evolved a rather novel solution.
For us mammals, the key to getting rid of waste ammonia is to detoxify it into urea in the liver. Marine organisms can employ the rather simpler solution of allowing the toxic ammonia to diffuse into their environment. However,
People who live in neighborhoods where stores, schools and homes are within walking or cycling distance from each other make almost twice as many weekly trips on foot as residents of less “walkable” neighborhoods, according to new research.
And all that car-free traveling can add up to better health: One or two extra walking trips a week can burn off enough calories to drop nearly two pounds in a year, which is about how much weight American adults gain annually.
If a large propo
Vitamin C helped convert mouse embryonic stem cells growing in the laboratory to heart muscle cells, researchers report todays rapid track publication of Circulation: Journal of the American Heart Association.
Rapid track articles are released online early because they have major clinical impact or represent important basic science discoveries. This basic-research discovery could lead to future research on ways to treat people suffering from damaged heart muscle.

Researchers have found disturbing new evidence suggesting that environmental exposure to a ubiquitous substance may cause chromosomally abnormal pregnancies. They have learned that low levels of a compound used in the manufacture of common plastic food and beverage containers and baby bottles interfere with cell division in the eggs of female mice. The disruption of cell division can result in an abnormal number of chromosomes in the eggs, a condition known as aneuploidy, which is the leading cause o
