While government leaders argue about the practicality of reducing world emissions of carbon dioxide, scientists and engineers are seeking ways to make it happen. One group of engineers at MIT decided…

What are the methods of prenatal diagnosis? There are two groups: invasive and non-invasive techniques: Non-invasive methods: examination of the uterus from outside the body (see Leopold's…

Virginia Tech researchers in computer science and biology have used the university's supercomputer, System X, to create models and algorithms that make it possible to simulate the cell cycle -- the…

The first major global assessment of climate change science in six years has concluded that changes in the atmosphere, the oceans and glaciers and ice caps show unequivocally that the world is…

UAB (University of Alabama at Birmingham) researchers have developed a method to increase bone density in mice, a development that might have future benefit for humans in the treatment of…

In an advance that could lead to composite materials with virtually limitless performance capabilities, a University of Wisconsin-Madison scientist has dispelled a 50-year-old theoretical notion that…

For the first time, scientists have observed DNA being damaged by ultraviolet (UV) light. Ohio State University chemists and their colleagues in Germany used a special technique to watch strands of…
