As illustrated with OnScreen Gene Transcription in our May 1 column, OnScreen Science now has a few very nice iPad apps to teach students about DNA and RNA. The OnScreen DNA Model app was the original ...

In the search to displace petrochemicals as feedstocks for materials, many researchers have focused on compounds from biomass that are abundant, such as sugars, proteins, and cellulose. Now, a simple ...

It is possible to classify images simply by analysing the way that trillions of DNA molecules in a test tube connect together into different shapes. Conventional computers must be fully assembled ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...
