Looks like this guy:
Is the cartoon version of this guy:
It walks. It breathes air. And apparently it can adapt to terrestrial life relatively “easily”.
The scientists raised groups of bichir on land for eight months to find out how they would differ from bichir raised in the water. They found that the land-raised fish lifted their heads higher, held their fins closer to their bodies, took faster steps, undulated their tails less frequently and had fins that slipped less often than bichir raised in water. The land-raised fish also underwent changes in their skeletons and musculature that probably paved the way for their changes in behavior. All in all, these alterations helped bichir move more effectively on land.
There’s a video too!
Apparently, that Science cover was pretty bad and plenty of people cared.
I got 75 responses in time to make the above figure (where the width of the blocks are proportional to the number of responses in each category)- 80% said the cover image was either very or kind of poorly chosen and 55% said they cared at least a little bit. The colored “lines” between the two answers depict how frequently two answers were chosen together and clicking the image will make it bigger. Thanks to everyone who gave me their 2 cents – such science. such wow.
The July 11 cover of Sciencegot a lot of press coverage last week. You can read about the variety of responses here, here, here, here or here (to name a few). But if you haven’t heard, Science chose to feature transgender sex workers from Jakarta on the cover of their “Staying a step ahead of HIV/AIDS” special issue, allegedly to highlight this “at risk” group. Unfortunately, the choice felt mostly like objectification and/or exploitation to some because the image was sexual (high heels, short skirts and the women were head/face-less). After a Twitter storm – including some pretty unprofessional responses from a Science editor – Science issued a short apology (cover image can be seen here too).
I’ve been wondering what the masses really think about this.
(survey now closed – results are here!)
… for people to please answer as honestly as possible. Basically, how well chosen do you think the cover art was and how much do you care?
Thanks you guys! I’ll post the responses in a week or so. Did I mention please answer? There are even “I don’t know” and “I don’t care” options, so everyone can participate!
On the scale of Bruce Banner to Incredible Hulk – how angry are you?
PS – All the “Staying a step ahead of HIV/AIDS” articles are open access! Check ‘em out!
Is this cuddly mug the future face of teaching?
I’ve recently become a big fan of IPython Notebook – I use it to keep track of command-line analyses and the thoughts/rationale/questions I have as I’m running them. But Greg Caporaso has another good use – an interactive textbook for teaching bioinformatics. In this blog post, he describes in detail how the textbook came about and how to get a copy for yourself.
Because the IPython Notebooks are interactive, students can (and actually do!) work with the notebooks in class and at home to experiment with the code, which drives active learning of the concepts. For example, one student this semester told us about his experiments with Smith-Waterman gap open penalties of 1000, and about what happens when you make the gap penalties negative (so they effectively become gap rewards; hint: you get a lot of gaps, but if want to see for yourself, install the notebook and try it out).
