Medical experiments on chimpanzees can be invasive, involving injections, blood samples and liver biopsies. But some say it’s the only way to advance medicine.
In recent years, Japan, Europe and the U.K. have all ended the practice. The U.S. and Gabon are the only two nations to continue using chimpz for medical research.
Are there ever instances in which the scientific value of research should offset the moral cost of working with chimps? What are your thoughts on this?
Followers, what say you?
On average, one baby is born in the United States each hour addicted to opiates — a class of drugs ranging from heroin to prescription painkillers.
Gina Glover, a photographer with a degree in Human Genetics, is the creator of these amazing works of art. “Chromosomal Stripy Socks” won the Medical Research Council/Novartis/Daily Telegraph Visions of Science award and appeared on the cover of Nature.
If you are interested in science photography or the intersection of art and science I highly recommend reading the interview!

Lungs ≡ Trees
Above is a resin cast of a lung. Notice its fractal nature - how it displays self similarity at smaller and smaller scales. You might also notice how this structure is quite ‘tree-like’. Why are they so similar?
Well actually, both lungs and trees want to maximise the surface area of their functional components while constrained to some maximum volume. For lungs this strict constraint is the size of the thorax, but for trees is more relaxed and is to do with the mass they can achieve through photosynthesis and mineral uptake and density of trees around them.
Interestingly, nature has solved both these mathematical problems of optimisation using the mathematical solution of fractals. This is a great example of complexity and universality. Complex structures such as trees and lungs emerge from very simple mathematical rules, laws and constraints. The result is some kind of universality to the structures that we humans see and assume to be very different, though they are fundamentally the same.
Check out this animation I made of a simple fractal construct being transformed into a ‘tree-like’ (or ‘lung-like’!) structure.

Insert completely necessary Flying Spaghetti Monster comment.
For some reason this reminded me of R.L. Stine. Also, Haruki Murakami has a twitter, where all he does is quote about spaghetti. He should see this.
I hope this works, and this wont be the first of my cheesy chemistry gifs.
I didn’t just spend my evening doing this.
A simple technique dramatically improved the memory recall of Harvard Medical School students. Try it for yourself!
Turning a medical student into a doctor takes a whole lot of knowledge. B. Price Kerfoot, an associate professor of surgery at Harvard Medical School, was frustrated at how much knowledge his students seemed to forget over the course of their education. He suspected this was because they engaged in what he calls “binge and purge” learning: They stuffed themselves full of facts and then spewed them out at test time. Research in cognitive science shows that this is a very poor way to retain information, as Kerfoot discovered when he went looking in the academic literature for answers. But he also stumbled upon a method that really is effective, called spaced repetition. Kerfoot devised a simple digital tool to make engaging in spaced repetition almost effortless. In more than two dozen studies published over the past five years, he has demonstrated that spaced repetition works, increasing knowledge retention by up to 50 percent. And Kerfoot’s method is easily adapted by anyone who needs to learn and remember, not just those pursuing MDs.
Also just a bit of advice for exams - it always helps to study as if your exam is all essays, instead of multiple choice. Studies have shown that students who study for essay exams do much better, and remember more.
