Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell. The chemists are exploiting a process called 'resonance energy transfer,' which occurs when fluorescent dye molecules are added to the nanoparticles. Their findings will be reported at the 234th annual national American Chemical Society meeting 19-24 August in Boston…
Scientists have suspected that the three known domains of life - eukaryotes, bacteria, and archaea - branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task. Now, a team of scientists present direct evidence that the three domains of life coexisted at least as long as 2.7 billion years ago…
