DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays an important role in certain processes such as the making of proteins.

Hard as it is to imagine, there's a move afoot in Congress to take away the public's free online access to tax-funded medical research findings. That would be bad for medical discovery, bad for patients looking for the latest research results, and another rip-off of the American taxpayer.

Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

A lot of medicines are not there to cure diseases. That's fine - drugs that keep people alive who wouldn't otherwise be alive are useful. What I object to is the drug companies' advertising, which you see everywhere in the U.S., which claims that they are curing diseases when they're not.

From age 16 on, I found school boring and failed A-level Physics at my first attempt. This was necessary for university entrance, and so I stayed an extra year to repeat it. This time, I did splendidly and was admitted to Sheffield University, my first choice because of their excellent Chemistry Department.
