In today’s Times, Nicholas Wade reports on a potentially serious, besides costly, problem for biomedical researchers: Human DNA Contamination Seen in Genome Databases. He writes: Nearly 20 percent of the nonhuman genomes held in computer databases are contaminated with human DNA, presumably from the researchers who prepared the samples, say scientists who chanced upon the […]
Franklin’s story starts like this: She was born in 1920 to a Jewish family in London. She excelled in math and science. She studied physical chemistry at Cambridge, where she received her undergraduate degree in 1941. After performing research in photochemistry in the following year on scholarship, she joined the British Coal Utilisation Research Association (BCURA) and carried out basic investigations on the micro-structure of coal and carbon compounds, and so earned a Ph.D. from Cambridge University. She was a polyglot, and next found herself in Paris at the Laboratoire Central des Services Chimique de l’Etat, where she picked up some fine skills in x-ray crystallography.
You get the picture: she was smart, well-educated and totally immersed in physical chemistry before, during and after WWII. Single-minded and focused, you might say –
Earlier this month employees at most of 7500 Walgreens pharmacies geared up to stock a new item on their shelves: a saliva sampler for personal genetic testing. On May 11, officials at Pathway Genomics, a San Diego-based biotech firm, announced they’d sell over-the-counter spit kits for around $25 through an arrangement with the retailer. A curious consumer could follow the simple package instructions and send their stuff in a plastic tube, provided in a handy box with pre-paid postage, for DNA analysis.
