...study in the Proceedings of the National Academy of Science (PNAS) says yes. A team led by Michael McElroy at Harvard University assessed the global capacity for wind power - the total amount of sheer energy that's being carried on the breeze - and found that current technology could harness enough power to supply more than 40 times the planet's present-day levels of electricity consumption. For the U.S., there's enough wind concentrated in the Midwest prairie states to supply as much as 16 times the current American demand for electricity. The energy is there, on the breeze...
...test is based on a protein excreted in the urine by patients who have an infection in the appendix. Led by Dr. Richard Bachur, chief of emergency medicine at Children's Hospital Boston, researchers discovered the hallmark protein by collecting and analyzing urine samples from 12 pediatric patients with confirmed cases of appendicitis (determined by inspection of the appendix after surgery). From an initial result involving thousands of different proteins, researchers narrowed the potential candidates by comparing the 12 samples to those from healthy children without appendicitis. "We analyzed the proteins to see which were statistically significant compared with...

There are currently only a little more than 1 million domestic phone lines - about 5 per 100 inhabitants - although just 10% belong to individuals or households. Unauthorized international calls abroad can lead to fines and arrest and in one case reportedly led to the public execution of a plant manager in October 2007, according to Good Friends, a Seoul-based aid organization. The same fears of the outside world will mean a very cautious and slow opening of the Internet, which is now reserved for trusted government officials and foreigners...
