Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development
... this study was devised by Young and Melikyan last year to investigate viral infection in a manner as close to 'real life' as possible. The researchers filmed the microscopic viruses, which are only 100 nanometers across, by labeling them with fluorescent dyes and recording at one frame every 7 seconds.

In a study published last year in the journal Nature, other researchers contended that Neanderthal teeth took 15 percent less time to reach maturity than those in later Homo sapiens, suggesting to them that a Neanderthal childhood would be shorter than our own.
