The Holy Grail of hemophilia treatment

[podcast]http://edwardwillett.com/wp-content/uploads//2011/12/Hemophilia-Gene-Therapy.mp3[/podcast] Over more than two decades of science writing, I’ve seen a lot of my past writings rendered obsolete by scientific progress. Case in point: the release last week of a research report on exciting new progress in gene therapy for hemophiliacs. Back in 2001, I wrote a book on hemophilia for the Enslow Publishers series Diseases and People (<brag>School Library Journal called it: “An excellent resource for basic research for personal or academic use.”</brag>). Gene therapy—the insertion of genes into living cells in the human body to treat disorders—has always seemed to hold particular promise for the treatment of hemophilia because it is a genetic disease: you can’t catch it, you can only ...

Confessions of a cyberchondriac

A few years ago I wrote several children's books for the Diseases and People series put out by Enslow Publishers. It's amazing when you're writing about disease how easy it is to convince yourself you've got the symptoms of whatever you're writing about. The first book was Meningitis. Stiff neck? You bet. Of course, I was sitting and typing for hours on end, but I'm sure that was just a coincidence. I also wrote Arthritis (my fingers are still stiff), Ebola Virus (Ebola starts with flu-like symptoms; gee, thanks, that's specific!), Alzheimer's Disease (which I can barely even remember writing) and Hemophilia, ...

A treatment for Ebola?

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/06/A-Treatment-for-Ebola.mp3[/podcast] A few years ago I wrote several books for Enslow Publishers in New Jersey for a series called Diseases and People. I covered meningitis, arthritis, hemophilia...and Ebola. My most recent book for Enslow, Disease-Hunting Scientist, also talks about Ebola, and some of the scientists who travel to the sites of outbreaks to help with containment efforts. Ask someone on the street to name a particularly deadly disease, and there’s a good chance he’ll say “Ebola.” Yet of the diseases I wrote about, the biggest killer by far is meningitis, the bacterial form of which kills some 170,000 people every year, according to the World Health Organization. (And if you want even bigger killers, in sub-Saharan Africa alone tuberculosis kills some 5,000 ...

Disease-Hunting Scientists: Jonathan Epstein and the search for SARS

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/05/jonathan-epstein-and-sars.mp3[/podcast] My next book, due out this summer from Enslow Publishers, is entitled Disease-Hunting Scientist: Careers Hunting Deadly Diseases. Each of its chapters focuses on one particular scientist whose work is related to hunting disease. The chapters are much longer than these science columns, but I thought in honour of the book’s release, I’d try over the next little while to boil down some of those chapters into columns. Call it the Reader’s Digest Condensed Books Version—not just condensed, but extremely condensed! One chapter focuses on Jonathan Epstein, a veterinarian epidemiologist with the Consortium for Conservation Medicine. In 2005, he led the first of five expeditions into China that eventually determined that bats were the “natural reservoir” of the ...

An instantaneous, universal, programmable vaccine?

[podcast]http://edwardwillett.com/wp-content/uploads/2009/03/a-universal-instant-vaccine.mp3[/podcast] Efforts to immunize people against disease go back to at least 600 B.C., when the Chinese attempted to immunize people against smallpox by putting smallpox material in their nostrils (the permitting of which, I would think, would require a great deal of faith in your doctor). Modern immunization began in 1796 when a British physician, Edward Jenner, noting that people who had had the much-less-deadly cowpox did not catch smallpox, inserted material from cowpox sores into the arm of a healthy eight-year-old boy. The boy caught cowpox, but when he was exposed to smallpox eight weeks later, he did not contract the often-fatal disease. Vaccines have since become a mainstay of public health. Their impact has been enormous. Consider measles: in 2007, ...

Title page of my next children’s non-fiction book

Just got the PDF of the rough layout of what will probably* be my next-published children's non-fiction book, Disease-Hunting Scientist: Careers Hunting Deadly Diseases--that's the title page at left. It's part of a series from Enslow Publishers called Wild Science Careers.It's been interesting to work on, since I got to interview several scientists who have studied diseases as varied as Marburg, Ebola, bird flu, SARS and black-band disease in coral. The focus of the series is on scientists who work "in the field," as opposed to just in a lab, so these men and women have travelled all over the world, waded through swamps, camped out in the ...

Why is winter the flu season?

Scientists may have finally figured out why there's a "flu season," why flu is so much more prevalent during the cold months:Dr. Zimmerberg and his colleagues found that at temperatures slightly above freezing, the virus's lipid covering solidified into a gel. As temperatures approach 60 degrees Fahrenheit, the covering gradually thaws, eventually melting to a soupy mix.Cooler temperatures, apparently, cause the virus to form the rubbery outer covering that can withstand travel from person to person, Dr. Zimmerberg said. Once in the respiratory tract, the warm temperature in the body causes the covering to melt to its liquid form, so that the virus can infect the cells of its new host, he added.This ...

What’s it like in Level 4?

Download the audio version.Get my science column weekly as a podcast.***It’s a staple of movies and TV shows: the Level 4 lab, where scientists in “space suits” race against the clock to find a cure for a mysterious ailment.But what’s it like to work in a Level 4 laboratory in real life?Dr. James Strong knows. He’s head of the cell biology section of the department of special pathogens at the National Microbiology Laboratory in Winnipeg, where he is researching how Ebola is transmitted from animals to humans.Strong spends a couple of hours in the Level 4 lab more days than not, and I recently had a chance ...

Here’s hoping it works!

A universal 'flu vaccine is in the first stage of human tests:This vaccine is intended to provide protection against all ‘A’ strains of the virus that causes human influenza, including pandemic strains.***At the moment, Phase I clinical trials on humans are underway - that is, the candidate vaccine is being administered to a small group of healthy people in order to verify the safety of the product and to provide an initial insight into the vaccine’s effect on the human immune system.***...they hope that annual flu vaccines can ultimately be replaced by the new, universal flu vaccine. The goal for this vaccine is that two inoculations would suffice to protect ...
