Papers of DNA Pioneer and Nobel Laureate Francis Crick Added to National Library of Medicine’s Profiles in Science Web Site

...ocesses of life, including human consciousness and free will, can be reduced to fundamental laws of physics and chemistry, and can thus be explained entirely in rational, scientific terms. After 1953, Crick devoted most of his effort to solving the genetic coding problem, the problem of how genes control...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...onies of seabirds accustomed to nesting on islands free of predators began disappearing when fur traders started introducing foxes onto islands in the Aleutian archipelago in the 18th century. The ground-nesting birds made easy meals for the foxes. A study published this week in the journal Science now sh...

Fortunately, the mitochondrion is nearly the same size as the light wavelength of about 800 nanometers, a frequency otherwise little absorbed by the body. Because of this close match, the laser is exquisitely sensitive to subtl...

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

... "When you start a normal reaction, molecules are free in solution so they interact with each other randomly," Akhremitchev said. "If you want to dissect the process, you would rather want to study interactions individually." Thus, the Duke chemists capture individual monomers at the end of long chained...
