- Toms River: A New Classic in Epidemiology Writing May 23, 2013
  This week Larry Lewis, PhD, contributes a book review. Dan Fagin, director of the Science, Health and Environmental Reporting Program at New York University, and his army of student assistants, do a great job in “Toms River” of describing the environmental catastrophe in Toms River, NJ.… Read the rest […]

- A Little Girl With Giant Axons, a Deranged Cytoskeleton, and Someday Gene Therapy May 16, 2013
  “When you hear hoof beats, think horses, not zebras.” So goes the mantra of first-year medical students. If a common disease is a horse and a rare disease a zebra, then giant axonal neuropathy (GAN), with only 50 or so recognized cases worldwide, is surely a unicorn.… Read the rest […]

- Celebrating Gleevec – and Basic Research May 9, 2013
  When 23-year-old Glamour magazine editor Erin Zammett Ruddy went for a routine physical in November 2001, she expected reassurance that her healthy lifestyle had been keeping her well. After all, she felt great. What Erin received, a few days later, was a shock.… Read the rest […]

- Confessions of a D Orbital May 2, 2013
  Organic chemistry has changed! Not the science, but the way it’s taught. SUNY Stony Brook, Fall semester, 1973. 500+ wannabe doctors pack into the lecture hall, squinting as a small figure up front slaps down overheads, scribbling CHNOPS atoms and various dots and dashes, changing the acetate sheets faster than any human brain can register them.… Read the re […]

- DNA Day and World Malaria Day: The Sickle Cell/Malaria Link Revisited April 25, 2013
  Today is both DNA Day and World Malaria Day. As I was pondering how to connect the topics, e-mail arrived from my “son,” a medical student in Liberia. He had malaria, again, and this time it had gone to his brain.… Read the rest […]

- DNA Day and 20 Years of Writing a Human Genetics Textbook April 18, 2013
  This month we celebrate the DNA anniversaries: unveiling of DNA’s structure in 1953, and the human genome sequence in 2003. From now until DNA Day, April 25, bloggers will be worshipping the human genome. Nature.com will offer podcasts (PastCasts) and last week, Eric Green, director of the National Human Genome Research Institute, spoke to reporters, summari […]

- A GPS View of the Human Genome April 11, 2013
  Taking cues from global positioning satellites, Yuval Itan, PhD, a postdoctoral researcher at Rockefeller University and his colleagues have created the “human gene connectome” (HGC), unveiled in Proceedings of the National Academy of Sciences. A MAP BASED ON FUNCTION Researchers have been deducing gene lineages for decades, based on DNA sequence similaritie […]

- Genetic Modifiers: Healthy Mutants Fuel Drug Discovery April 4, 2013
  I’m uneasy counseling a patient for mutations in the BRCA1 or BRCA2 cancer susceptibility genes. Typically, she’ll have a “first degree relative” – usually a mother or sister – with a related cancer, or might even have a test result in hand.… Read the rest […]

- Mayonnaise Taxonomy March 28, 2013
  I had a serious genetics topic all set to go today, but then something more timely and compelling arose. I began to wonder about what, exactly, mayonnaise is, and more importantly, how do the types of mayonnaise differ? My musings started with Passover, and the importance of eggs at this time of year.… Read the rest […]

- Second Gene Causes Retinoblastoma March 21, 2013
  In a list of famous genes, RB1 would probably be #1. It’s the tumor suppressor gene whose “loss of function” is behind the childhood eye cancer retinoblastoma, and that Alfred Knudson investigated to deduce the 2-hit mechanism of cancer. In 1971, the idea that a gene’s normal function could be to prevent cancer was revolutionary.… Read the rest […]
