Poking Holes in Genetic Privacy
By GINA KOLATA
Not so long ago, people who provided DNA in the course of research studies were told that their privacy was assured. Their DNA sequences were on publicly available Web sites, yes, but they did not include names or other obvious identifiers. These were research databases, scientists said, not like the forensic DNA banks being gathered by the F.B.I. and police departments.
…
Experts were startled by what Dr. Erlich had done. “We are in what I call an awareness moment,” said Eric D. Green, director of the National Human Genome Research Institute at the National Institutes of Health.
Research subjects who share their DNA may risk a loss of not just their own privacy but also that of their children and grandchildren, who will inherit many of the same genes, said Mark B. Gerstein, a Yale professor who studies large genetic databases.

In a nutshell:
• Scientists deliver the first high-resolution sequence of HeLa cells, a key research tool for human disease and general biology
• Sequence analysis reveals the full extent to which HeLa cells are different to the Human Genome Project reference
• Resource could enhance the quality of research using HeLa cells

Choosing sunscreen for your kids: Organic or mineral? SPF 30 or 50? Spray or lotion? Help. – Slate Magazine
June 11, 2013Interesting scientific primer, absorbers v reflectors (Zinc oxide), “Organic sunscreens often contain oxybenzone”. These have the issue of free radical formation.
QT:”
Some sunscreen companies add antioxidants like vitamin E and vitamin C to their formulations as well to absorb some of these reactive compounds. One 2011 study found that the addition of antioxidants to SPF 15 or 50 sunscreen formulations reduced the numbers of reactive oxygen species in skin more than two-fold.
…
Retinyl palmitate, a form of vitamin A, is an antioxidant added to many sunscreens and cosmetics (it’s also a food additive, used to fortify some dairy products and cereals). Although the FDA considers retinyl palmitate to be safe, research suggests that upon interaction with UVA light, the compound produces reactive oxygen species. …
And what about application method—sprays, gels, wipes, or
old-fashioned lotions? The Environmental Working Group warns against sprays because of the risk that the chemicals could be inhaled or get into the eyes. But if your child won’t let you near her with anything but a cool mist, by all means use it—just ask him to hold his breath and close his eyes as you apply it. The EWG also warns against combination sunscreen/bug sprays, which may increase absorption of the repellant chemicals, and sunscreen wipes, which might not deliver adequate protection.
