Recent studies also indicate that Reolysin works synergistically with standard anti-cancer drugs, providing significantly stronger responses than either agent alone. In addition, other s...

Researchers attach genes to minichromosomes in maize

...ularly useful because they allow scientists to add numerous genes onto one minichromosome and manipulate those genes easily because they are all in one place, Birchler said. Genetic modification with traditional methods is more complicated because scientists have little control over where the genes are locate...
