BRITISH scientists have developed the world’s first stem cell therapy to cure the most common cause of blindness. Surgeons predict it will become a routine, one-hour procedure that will be generally available in six or seven years’ time.
The treatment involves replacing a layer of degenerated cells with new ones created from embryonic stem cells. It was pioneered by scientists and surgeons from the Institute of Ophthalmology at University College London and Moorfields eye hospital.

French researchers have developed a potentially very useful set of graphical icons to depict disease and drug information:
Like road signs, the VCM graphical language uses a small set of graphical signs. The current dictionary contains about 130 pictograms displayed in 5 colors. For example, current conditions of a patient are shown as red icons while risks of future conditions are orange. The physicians who tested the system learned it in a couple of hours and think this system will reduce the number of errors in drug prescriptions.
I think a universal, simplified set of icons is a great idea. Of course they wouldn’t be a replacement for drug information sheets, etc., but they could allow doctors and pharmacist to quickly identify a substance and work more safely and efficiently.
Orac has a nice rejoinder to David Kirby’s recent article, which contained the following disheartening, if not unsurprising news:
Senator Hillary Clinton, in response to a questionnaire from the autism activist group A-CHAMP, wrote that she was “Committed to make investments to find the causes of autism, including possible environmental causes like vaccines.” And when asked if she would support a study of vaccinated vs. unvaccinated children, she said: “Yes. We don’t know what, if any, kind of link there is between vaccines and autism – but we should find out.”And now, yesterday, at a rally in Pennsylvania, Barack Obama had this rather surprising thing to say:
“We’ve seen just a skyrocketing autism rate. Some people are suspicious that it’s connected to the vaccines. This person included. The science right now is inconclusive, but we have to research it.”
(Note: The Washington Post reports that when Obama said “this person,” he pointed to someone who had asked an autism question).
Orac contends (and I agree) that the problem isn’t the answers themselves, but rather that they answered at all (his notes and links, not mine):
In essence, both candidates accepted some of the major pillars of the mercury militia’s fantasies as being true. These include claims that:
- there is an autism “epidemic.” (Arguably, there is very likely not.)
- there is a scientific controversy over whether vaccines cause autism. (There really isn’t; it’s a so-called manufactured controversy. There is no good evidence that vaccines cause autism, David Kirby’s bloviations and pontifications otherwise notwithstanding. Multiple large epidemiological studies have failed to find even a hint of a convincing link, and the publicizing of the Hannah Poling case as some sort of “smoking gun” by antivaccinationists is nothing more than a rebranding of autism and more evidence of the incredibly shrinking vaccine claim.)
- that vaccines are somehow unsafe or that children are “overvaccinated” and eceive too many vaccines. (Again, there is no good evidence that either of these is the case.)
And of course, John McCain is even worse.
FRONTLINE does yet another great job as one of the only remaining investigative journalism outfit in America. It’s kind of like Sicko without the persuasive slant, though it is done in an editorial/feature style. You can watch it entirely online (because PBS is awesome), and there’s even a little bonus footage at the end where he explores Ayurvedic medicine. One of the great things about watching Frontline online is the little text popups that link to informative pages, such as this one, that contained a few very interesting graphs (click for bigger):
You’ll notice that the US spends far more money to far less effect than the other nations gathered in these charts (data gathered from a 2007 report by the Organisation for Economic Co-operation and Development (OECD)). Another really interesting section is on how different countries compensate doctors and deal with malpractice. I thought the author made a really excellent point when he said that the current presidential candidates are mentioning health care reform, but not one is referring to how we can emulate more effective systems from other parts of the world.
Into the Fray Over the Cause of Autism – New York Times
“It’s indisputable that autism is on the rise among children,” Senator John McCain said while campaigning recently in Texas. “The question is, What’s causing it? And we go back and forth, and there’s strong evidence that indicates that it’s got to do with a preservative in vaccines.”
Not as if I need another reason not to vote for McCain… I’ve posted numerous refutations of the thimerosal-autism link here before, and this one‘s as good as any. You can also take a look here [NSFW] at what happens when you don’t immunize children, but I’ll warn you the pictures are pretty graphic. Here’s my favorite Metafilter comment from a now-deleted thread:
It’s mercury, a neurotoxin.
You know what else is a toxin? Chlorine. That’s right: it corrodes sensitive mucous membranes and can digest living cells. I therefore suggest you stay away from table salt — it contains chlorine, you know. Clearly toxic!
Researchers create new rat heart in lab
Medicines dream of growing new human hearts and other organs to repair or replace damaged ones received a significant boost Sunday when researchers at the University of Minnesota reported success in creating a beating rat heart in a laboratory.
I can’t imagine what it must have been like to see that heart start beating. Creepy/cool, probably.
Childrens Hospital Boston has some really cool stuff on its web page:
Experiment with Childrens virtual neuron to see what conditions are needed to make it fire and what happens when you connect it to other neurons. This interactive feature also provides step-through animations illustrating how electrical currents move through the cell and how it passes signals on to other neurons.
