Data from the United Kingdom's Civil Aviation Authority showed that air rage incidents among British passengers have tripled over the past five years. Pilots blamed the rise on plane delays which led bored and angry passengers to take up drinking as a way to pass the time, leading to inflight fights. From January to March, the CAA recorded 601 air rage incidents, up by 32 percent from 458 cases logged for the first quarter of 2007. For the same period in 2003, only 214 such incidents were on record.

It is possible to be fat and fit at the same time, a surprising new study has revealed. In the first national study of its kind, researchers found that at least half of overweight adults, and close to a third of obese men and women, have normal blood pressure, cholesterol and other measures of heart health. Researchers from the University of Michigan also found that close to a quarter of U. S. adults in the recommended-weight range had risk factors for heart disease or diabetes. That means some 16 million of them are at risk for heart problems, the study said.

Scientists at the University of California, Berkeley, have been able to hide three-dimensional objects by using artificially engineered materials that redirected lights around the object. The discovery is one step closer to hiding people and objects from visible light. The researchers, led by Xiang Zhang, used metamaterials that deflected light, radar or other waves around an object such as water flowing around a smooth stone in a river.

Two common fertility treatments involving an ovary-stimulating drug and artificial insemination to improve the chances of conceiving a child yields the same results as no treatment at all, according to a study published Friday. Clomifene citrate, best known by its brand names Clomid and Serophene, a drug used by millions of women in recent decades to stimulate ovaries to produce eggs, failed to improve the odds of becoming pregnant, researchers in Britain said.

A female Eastern box turtle called Turtle No. 72 has led Washington police to a well-tended marijuana garden in Rock Creek Park. The turtle is one of 135 wired animals with a small radio transmitter on its shell to provide scientists data on turtle movements. The six-inch turtle wanders through 50 acres near the District-Maryland boundary.
