...When olfactory cells regenerate, they grow long neural shoots called axons, which connect to the brain. The axons are like phone wires that carry the signals that allow the brain to differentiate between various smells. They transport these signals with the help of olfactory ensheathing glia (OEG) cells. Because axons extend from all nerve cells, scientists have long wondered what would happen if OEG cells were taken from the olfactory bulb and introduced somewhere else?say, in the spinal cord of someone like Nan Davis...
...People tend to think of forests as pretty slow changing," says Craig Allen, an ecologist with the U.S. Geological Survey. "But once certain thresholds are exceeded, very rapid changes can occur." In some cases, thirsting trees perish because their circulatory systems--the long tubular columns in the trunk that transport water from the roots to the crown--collapse. In other cases, the trees become so weak they can no longer fend off insects and disease...
...oxygen-carrying workhorse in red blood cells. Artificial blood has long been a dream of doctors who face perpetual blood shortages, and in recent years that dream is closer to becoming reality. One promising approach involves extracting hemoglobin from living cells and using it alone as an oxygen transport system. Unfortunately, naked hemoglobin is quickly broken down in the body. Housing the hemoglobin in an artificial cell, or modifying the hemoglobin so it remains stable, could solve this problem. Two such artificial hemoglobin-based blood products in the final stages of development are already rumored to have made the rounds...
...wider allegations of sexual impropriety shut down the college. In the Frame ROMANIA Prosecutors indicted Bucharest Mayor Traian Basescu and 79 other officials on charges of fraud in relation to the sale of state-owned ships in the early 1990s, at an alleged loss of €275 million. Basescu, Transport Minister at the time of the sale, said the charges were politically motivated. He is co-leader of the opposition Truth and Justice Alliance, which is nudging ahead of the government in opinion polls in the run-up to November's legislative and presidential elections.

...city epitomizes the perfect storm engulfing Asia's roads, it is surely India's capital, New Delhi. Swarming the city's potholed streets are 4 million cars and trucks, 600,000 motorized two- and three-wheeled vehicles and innumerable bicycles and nonmotorized forms of transport ranging from trishaws to ox carts. There are also animals, everything from sacred cows to dogs, cats, monkeys?as well as countless pedestrians. The latter do not fare well in this free-for-all. New Delhi's newspapers recently labeled the city a "pedestrian graveyard." According to the capital's transport department, nearly half...
