In 1953, the solution to the problem was found and printed by an IBM 701 computer in 12 minutes...

Protein found in yeast and humans appears to play a key role in regulating cell growth

Environmental issues fail to capture national interest, says Temple University professor on eve of 30th Earth Day celebration

"Sadly, one of the things that propels that interest is some sort of environmental disaster like Three Mile Island, Chernobyl, or the Exxon Valdez oil spill, which spurred a lot of interest at the time of the 20th anniversary of Earth Day." He also believes that educating ch...

New genes protect trees from insects, disease

... over the course of millions of years. "One of the things we want to determine," he says, "is how they communicate with one another--how do they each let the other know that they are friendly." He says the process is a long one. "It's almost like a courtship. The fungus gradually approaches the tree root s...

South Dakota windbreaks need renovation

People aren't the only things that age. South Dakota windbreaks and shelterbelts, planted in the 1920's and 1930's are showing their age too. Today, mature trees occupy 71 percent of the timberland area in the state. In eastern South Dakota many of those stands were planted as...

Potential gene therapy carriers created that mimic viruses, without the risk

Chemical from venom of Chilean tarantula could aid treatment of heart attack, other major diseases

Mice unable to synthesize vitamin C should become valuable research tool, scientists say
