Science Tidbits June 19, 2012

Fast one today, as I spent a fair bit of time today at the Lexington Humane Society making friends with the cats and dogs. It’s June, which means that there are lots of adorable little kittens out there in need of homes, but don’t overlook the wonderful adult animals out there. We have three cats from LHS, two of which were adopted as adults. It is easier to place kittens into loving homes than adult cats who lack the tiny furball cuteness of the larval cat. With an adult cat, though, you have the knowledge of what the cat’s personality is and you know that you have brought home a special friend that may have spent several months in a small cage. If you can’t give a cat a good home right now, consider making a donation of food or money (call first and find out what they need).

On with the show.


Top story, and for good reason, a Chicago woman has been cured of Sickle Cell Anemia! This isn’t a first ever, but is wonderful to see! Her bone marrow was killed via radiation and bone marrow carrying the gene for normal hemoglobin was transplanted. This is a pretty major intervention, as you can imagine, but it is great to see that some people are getting relief from this painful disease.

Most courses on genetics use Sickle Cell as an example of a disease where people carrying one copy of the gene are protected against malaria, but people with two copies have a lethal disease unless the disease is treated. Even then, most patients have a much shorter lifespan and have to deal with a painful disorder and side effects from the treatment. This gives us hope that better treatments could be within reach… but will require a much improved donor database.


Its National Pollinator Week, and Bug Girl has information on the importance of our pollinators. For a person who has kept honeybees, this is a week I can dance for. Insect collecting and photographing can be great projects for students from elementary school all the way up to undergraduate, with identification exercises, learning about habitat and ecological niches as needed. If some students are particularly interested, 4-H programs offer a chance for students to direct their own learning and to practice their public speaking skills.


Class discussion topic for all ages and a chance to discuss the history of the exploration of space: Is it time to return to the moon?


Following up on yesterday’s tidbit about mating strategies, the Giant Cuttlefish shows its colors.


A fast Toxic Tuesday, a returning feature of this blog, a quick list of several incredibly deadly proteins, running the gamut from ricin, produced by a bean, to botulinum, produced by a bacteria.


Finally, news on the textbook controversy in South Korea. Creationist groups had pressured publishers to remove evolution from textbooks without input from scientists. Scientists will now get their say, and hopefully this misadventure will end with science back in science texts.

Teach on.
