If BPA exposure is so low, why should we be worried?

by Melinda Moyer in Body Politic

In response to my earlier post about bisphenol A in soda and beer, reader Skeptic had an insightful comment:
As someone involved in environmental health myself, I have been following the BPA controversy from north of the 49th parallel with some interest. I have often wondered whether the actual data supports regulation of BPA. The first study you cite, for example, hides this line in its discussion: “Thus, median and 95th percentile intake estimates were approximately two to three orders of ma........ Read more »

Butterfly, heal thyself! (Or thy kids, anyway.)

by Jeremy Yoder in Denim and Tweed

Using specific compounds to cure disease seems like a fairly advanced behavior—it's necessary to recognize that you're sick, then know what to take to cure yourself, then go out and find it. You might be surprised to learn, then, that one of the best examples of self-medication behavior in a non-human animal isn't another primate species, or even another vertebrate. It's none other than monarch butterflies. Female monarchs infected with a particular parasite prefer to lay eggs on host plants t........ Read more »

It Takes A Village

by Journal Watch Online in Journal Watch Online

Restoring urban streams bruised by decades of abuse is hard enough. Pulling off a restoration project that is backed both by informed, supportive neighbors and good science is even harder. But along College Creek in Ames, Iowa, researchers, government officials and local residents have teamed up to show just how it might be done.

Mashing up banana wild relatives

by Jeremy in Agricultural Biodiversity Weblog

Over at the Vaviblog is a detailed discussion (though not nearly as detailed as the paper) of a new paper outlining a new theory for the origin of the cultivated banana. Edible bananas have very few seeds. Wild bananas are packed with seeds; there’s almost nothing there to eat. So how did edible bananas come [...]... Read more »

Banana domestication revisited

by Jeremy in The Vaviblog

Edible bananas have very few seeds. Wild bananas are packed with seeds; there’s almost nothing there to eat. So how did edible bananas come to be cultivated? The standard story is that some smart proto-farmer saw a spontaneous mutation and then propagated it vegetatively. Once the plant was growing, additional mutants would also be seen [...]...

Did cavemen eat bread?

by Razib Khan in Gene Expression

Food is a fraught topic. In How Pleasure Works Paul Bloom alludes to the thesis that while conservatives fixate on sexual purity, liberals fixate on culinary purity. For example, is it organic? What is the sourcing? Is it “authentic”? Obviously one can take issue with this characterization, especially its general class inflection (large swaths of [...]... Read more »

Wired to be Social

by Glialdance in Glial Dance

Humans are a social species, we interact with other people – aided by language- and exchange information on daily basis. The effects of social isolation have been demonstrated and predicted to be very severe and “de-humanising” in many cases with a long list of adverse effects on cognitive abilities and emotional stability. The question often posed when [...]... Read more »

Paging Dr. Monarch Mom

by Michael Gutbrod in A Scientific Nature

New research has shown that the ability to medicate exists outside of the realm of humanity.  There goes that God complex.  In the kingdom of life, there are few examples of behavior specifically directed at treating a disease or infection outside of the scribbling your doctor calls a prescription.  However, a new study out of [...]...

population genetics, evolution, and ocean ecosystems

I was trained as an Environmental Scientist long before I was at all interested in Microbes. So, I get excited when I come across microbial studies that are environmentally relevant. I get particularly nerd-cited when these studies take place in the ocean. A paper published in PNAS last week describes identifies what may be the [...]... Read more »

Last week I began a breakdown of this paper.

Smoking bans are good for barkeeps

by PalMD in White Coat Underground

Barkeep and blogger Scribbler has a piece up giving one bartender’s view of New York’s smoking ban.  Since I like Scribbler, I wondered what the data say about the effect of smoking bans on his health.  Cigarette smoke has many harmful physiologic effects, and the data are pretty clear that you don’t have to be [...]...

The Curious Tale of a Far-Flung Whale

by Laelaps in Laelaps

When marine biologists first spotted the humpback whale AHWC no. 1363, there did not appear to be anything remarkable about her at all. Seen with another female on the Abrolhos Bank off the coast of Brazil on August 7th, 1999, the whale simply stuck around long enough for the scientists to snap a few photographs [...]... Read more »

Spreading Salmonella—hyper-replicating bacteria act as a reservoir for dissemination

by geekheartsscience in geek!

New research reveals how Salmonella enterica spread in the gut and gallbladder—a subpopulation of Salmonella primed for invasion rapidly replicate in the host cell cytosol such that bacteria-laden cells are extruded out of the epithelial-cell layer releasing invasive Salmonella into the gastrointestinal and biliary lumen. Leigh Knodler and colleagues write that other mucosal-dwelling pathogens could [...]... Read more »

Crabs expose colliding continents

by Lucas in thoughtomics

Every high school student now learns that plate tectonics slowly drive our continents in different directions. Since only the most uncontroversial scientific knowledge finds its way to high school text books, it’s hard to imagine that when the theory of continental drift was proposed by Alfred Wegener in 1912, it was firmly rejected by [...]...
