Earlier this week, I was contacted by Daniel Zaharevitz, Chief of the Information Technology Branch of the Developmental Therapeutics Program at the National Cancer Institute. He is also involved with the NIH Roadmap Molecular Libraries Initiative. We had a very interesting talk about Open Science and what kind of further impact it could have in drug development. Lets just say that we are on the same page on this issue and I'm really impressed with what Dan is trying to achieve. The first thing we are going to do is start shipping the compounds we make for an automatic screening of 60 cell lines for tumor inhibitory activity.

I often find that books on the history of science and technology are fun to read because they give me an opportunity to try to forget what I know about how things turned out and piece together an older worldview. For example, I am currently reading the new book by Tom McNichol "AC/DC - The Savage Tale of the First Standards War". On p. 38 is reprinted part of Edison's article in North American Review, written in 1878, shortly after his invention of the phonograph:

Among the many uses to which the phonograph will be applied are the following: ... 2. Phonographic books, which will speak to blind people without effort on their part. ... 9.

New research from Columbia's Primate Cognition Laboratory has demonstrated for the first time that monkeys could acquire meta-cognitive skills: the ability to reflect about their thoughts and to assess their performance.

The study was a collaborative effort between Herbert Terrace, Columbia professor of psychology & psychiatry, and director of its Primate Cognition Laboratory, and two graduate students, Lisa Son — now professor of psychology at Barnard College — and UCLA postdoctoral researcher Nate Kornell.

The test used touch-screen technology and a multiple-choice format. Six novel photographs were presented at the beginning of each trial, one at a time.

Cilia, tiny hair-like structures that propel mucus out of airways, have to agree on the direction of the fluid flow to get things moving. Researchers at the Salk Institute for Biological Studies discovered a novel two-step mechanism that ensures that all cilia beat in unison.

Their study, published in Nature, reveals that during early embryonic development, cilia point more or less in the general direction of the body's back end and start creating a weak flow. During the following refinement phase, all cilia get in line and trim their sails to the prevailing winds.

Huntington’s disease, an inherited neurodegenerative disorder that affects roughly 30,000 Americans, is incurable and fatal. But a new discovery about how cells repair their DNA points to a possible way to stop or slow the onset of the disease. The research was funded by the National Institutes of Health (NIH).

"As so often happens, basic research on a fundamental biological process—in this case, enzymes involved in DNA repair—leads to new insights about how diseases arise and new approaches for treating or preventing them," said NIH Director Elias A. Zerhouni, M.D.

Ultra-hard materials are used for everything from drills that bore for oil and build new roads to scratch-resistant coatings for precision instruments and the face of your watch.

UCLA scientists are now reporting a promising new approach to designing super-hard materials, which are very difficult to scratch or crack.

An effective way to fight leukemia might be to knock out a specific protein that protects cancer cells from dying, a new study shows.

The findings suggest that a drug that can block this "survival protein" might on its own be an effective therapy.

Using a new type of drug that targets a specific genetic defect, researchers at the University of Pennsylvania School of Medicine, along with colleagues at PTC Therapeutics Inc. and the University of Massachusetts Medical School, have for the first time demonstrated restoration of muscle function in a mouse model of Duchenne's muscular dystrophy (DMD).

Crohn’s disease is a chronic relapsing inflammatory disorder of the intestinal tract that affects an estimated 0.15% of people in the developed world. Common symptoms include abdominal pain and diarrhea, but the disorder is often associated with debilitating clinical complications. Researchers from the University of Liège, Belgium, have now uncovered an important clue to the susceptibility of individuals to this disease.

Scientists have discovered one of the reasons why bladder cancer is so much more prevalent in men than women: A molecular receptor or protein that is much more active in men than women plays a role in the development of the disease. The finding could open the door to new types of treatment with the disease.

In an article in the April 4 issue of the Journal of the National Cancer Institute, Chawnshang Chang, Ph.D., of the University of Rochester Medical Center and colleagues show that the androgen receptor, which is central to the action of testosterone and other hormones that are much more plentiful in men than women, appears to play a key role in the disease.
