THE Darwin Fish.

Looks like this guy:

Is the cartoon version of this guy:

Cuvier’s Bichir

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!

Antibiotic Resistance For Everyone!

Everyone should know what antibiotic resistance is. According to the World Health Organization, “this serious threat is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country.” So, I hope this short “comic” helps make it clear why we should all be thinking about antibiotic use…

the OTHER microbiotas

The Body’s Ecosystem is a comprehensive – yet short enough to finish in a single sitting – review on current NON-GUT microbiota research, focusing on the mouth, lungs, swimsuit area, maternal microbiome and skin. It’s pretty interesting and pretty pretty – I really liked the accompanying artwork (including two hand-drawn, possibly NSFW genitalia pictures). It also features research from a couple UIdaho labs (m’ alma mater). In other words, a darn good read, in my opinion.
Altogether, the members of the human body’s microbial ecosystem make up anywhere from two to six pounds of a 200-pound adult’s total body weight, according to estimates from the Human Microbiome Project, launched in 2007 by the National Institutes of Health (NIH). The gastrointestinal tract is home to an overwhelming majority of these microbes, and, correspondingly, has attracted the most interest from the research community. But scientists are learning ever more about the microbiomes that inhabit parts of the body outside the gut, and they’re finding that these communities are likely just as important. Strong patterns, along with high diversity and variation across and within individuals, are recurring themes in microbiome research. While surveys of the body’s microbial communities continue, the field is also entering a second stage of inquiry: a quest to understand how the human microbiome promotes health or permits disease.

Just one of the pretty pretties in the article…

RESULTS from SURVEY: How bad was that Science cover and do you care?

Apparently, that Science cover was pretty bad and plenty of people cared.

surveyResults

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.

 

SURVEY: How bad was that Science cover and do you care?

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.

HERE IS MY 2 QUESTION SURVEY

(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!

The future of teaching?

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).

 

Friday Coffee Break

Every Friday at Nothing in Biology Makes Sense! our contributors pass around links to new scientific results, or science-y news, or videos of adorable wildlife, that they’re most likely to bring up while waiting in line for a latte.
