Why research articles should be publicly accessible (Shulenburger 2009, PLoS Biology)

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

I cannot even count the number of times when I have been denied access to a journal article I needed.  Oftentimes, it was while I was working on a paper in college and couldn’t read the paper that all the other scholars cited, or the paper that supported an argument I was trying to make.  [...]...

Identifying minimum patch sizes for breeding success in birds

by Rob Goldstein in Conservation Maven

A new study illustrates the importance of understanding the minimum patch size that an at-risk bird needs to reproduce. Jerrod Butcher and fellow researchers looked at the effect of habitat patch size on two songbirds in north-central Texas.... Read more »

Computer-assisted killing for conservation

by CJA Bradshaw in ConservationBytes

Many non-Australians might not know it, but Australia is overrun with feral vertebrates (not to mention weeds and invertebrates). We have millions of pigs, dogs, camels, goats, buffalo, deer, rabbits, cats, foxes and toads (to name a few). In a continent that separated from Gondwana about 80 million years ago, this allowed a fairly unique [...]... Read more »

Not Time of Day for Training but Location Location Location

by mc in begin to dig (b2d)

ResearchBlogging.orgThe question of time of day for training has been asked often. Better to train at night? better to train in the morning? Better for anaerobic? better for aerobic?
Indeed, one of my fave current studies has shown that the circadian clock is threaded right into the muscles - at least of mice... Read more »

Two tools for screening risk: STarT Back Tool and Örebro Musculoskeletal Pain Screening Questionnaire

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I wrote yesterday about the difficulty there is in grouping patients so that the right treatment is given to the right person at the right time. Today’s post coincidentally follows a similar line – two screening tools that discriminate between ‘high risk’ and ‘low risk’ people with low back pain. The value of [...]... Read more »

CAPRI or: What is the State of Protein-Protein Docking?

by Nir London in Macromolecular Modeling Blog

This is the first post in a series, summarizing the CAPRI (Critical Assessment of PRediction of Interactions) 4th Evaluation meeting. In this post I'll try to give a more personal perspective of the experiment results, the state and trends of computational protein-protein docking and the vibes behind the scenes. The next posts in the series will shortly summarize select talks from the meeting, kindly provided by the speakers.

Citizen Science: all fun and no data? ScienceOnline 2010

by Sandra Porter in Discovering Biology in a Digital World

Do citizen science efforts ever go beyond "feel good" contributions? Do the data get published in peer-reviewed journals?

In an earlier post, I started a list of citizen science projects that allow students to make a contribution. Many commentors are graciously adding to that list and I thank you all! I'm glad to learn there are so many interesting projects and ways for people to get involved. Science is so empowering!

My question today concerns things like outcomes and deliverables. We'd........ Read more »

Half plant, half predator, all wierd.

by Lab Rat in Lab Rat

I was planning on brushing up my knowledge of chloroplasts today, as next week I'm starting a plantsci course for my options lectures, but I got sidetracked by Captain Skellet alerting me to Hatena. I've heard of several organisms containing proto-plasmids; symbiotic chloroplasts which haven't completely been endosymbiosed, but Hatena was a new one so I went to look it up. And I'm very glad I did, because it's pretty amazing.Hatena, taken from the reference. Green blob is the symbiont. Scale bar........ Read more »

Scientists look to tobacco leaves for biofuel

by Katie Kline in EcoTone

This post was contributed by Piper Corp, ESA Science Policy Analyst
In a recent Plant Biotechnology Journal paper, scientists at Thomas Jefferson University’s Biotechnology Foundation Laboratories say that genetically modified tobacco “has the potential to produce more energy per hectare than any other non-food crop.”

So… Did knuckle walking evolve twice?

by zinjanthropus in A Primate of Modern Aspect

Almost certainly.
We had lots of clues that this was the case before Ardi, but now that we’ve got Ardi- the palmigrade extraordinaire, we know that humans did not go through a knuckle-walking phase, and that chimpanzee knuckle-walking has evolved since the split with our last common ancestor with them.  Which would also means that it [...]...

On evolution of the immune system

by iayork in Mystery Rays from Outer Space

As if understanding this complex evolutionary puzzle were not already sufficiently challenging, we have learned recently that two types of adaptive immune system have evolved in vertebrates: a recently recognized system in jawless vertebrates (hagfish and lamprey) and the more familiar adaptive immune system of jawed vertebrates. … This leads to the conjecture that two [...]...

Deconstructing Social Darwinism, Part III

by Eric Michael Johnson in The Primate Diaries

Part 1 / Part 2 / Part 3

In Quentin Skinner's celebrated history The Foundations of Modern Political Thought he writes that:

If the history of political theory were to be written essentially as a history of ideologies, one outcome might be a clearer understanding of the links between political theory and practice.

In Part II of this series I highlighted how a common objection to the political theory of social Darwinism is that it was a misapplication of Darwin's science to already existing id........ Read more »

Can rubber bullets rehabilitate a nuisance bear?

by Rob Goldstein in Conservation Maven

Can you change the behavior of a bear that raids campgrounds, nuzzles through trash, or knocks side view mirrors off cars? A new study finds evidence that a method called aversive conditioning can be successful in modifying the behavior of some bears but fully averting conflicts with humans will require changing how people act as well......
