Decline in ozone harming chemicals mostly due to drop in one solvent

The level of ozone-depleting chemicals in the atmosphere is falling, mostly because of reductions in one solvent, meaning further cuts can occur only if emissions of other chemicals are lowered, researchers say. "We have made progress, but we're not out of the woods yet," said Stephen A. Montzka of the National Oceanic and Atmospheric Administration.

New fusion reactor may provide clean energy

Researchers believe they have an answer to the world's mounting energy problem, and it's not the $10 billion experimental fusion reactor community leaders in the Aiken-Augusta area want for Savannah River Site. Their proposal: a cheaper and much smaller fusion machine they claim will produce enough electricity to power a city the size of Augusta for just a few dollars a day. Operating the reactor would not involve the hazards or yield the radioactive waste normally associated with nuclear power, they say.
DNA gets its decade in court

It was one of those chance-in-a-million things. Not long after she was raped, an Indiana woman thought she spotted her assailant on the street. Police arrested the man, took his blood and sent it to a crime lab for DNA analysis. Robert Flowers said he hadn't committed the crime, and lab results showed he was telling the truth: His DNA didn't match the rapist's. But it came so close, the laboratory just had to ask - could Robert Flowers have a brother? He could, and he did. And, eventually, Robert's look-alike brother was convicted of the rape.

Race relations As anthropologists learn more about how genes are spread among humans, they are starting to believe that there is no such thing as race. People around the world are more similar genetically than they are different, according to Alan R. Templeton, an evolutionary and population biologist at Washington University in St. Louis. All people share about 85 percent of the same genes, he reported in the journal American Anthropologist. That is not enough of a difference, he says, to separate people by race.
