A flawed study claiming prevention of Lyme spirochete infection with topical antibiotics

by Microbe Fan in Spirochetes Unwound

Two recent papers tested the effectiveness of topical antibiotics in preventing Borrelia burgdorferi infection in mice following a tick bite.  Infection by the Lyme disease spirochete was successfully halted in the Knauer et al. study from Germany1 but not in the Wormser et al. study conducted in New York.2  However a flaw in the Knauer study may have unfairly tipped the outcome in the antbiotic's favor.  (I'll save the Wormser study for another post.)The paper by Knauer and colle........

The Orange-Dotted Tuskfish Strikes Back: Movie Shows New Species of Fish Using Tool

by Paul Norris in AnimalWise

Recently, the blackspot tuskfish (Choerodon schoenleinii) became a media sensation when it was captured in photos using a rock as tool to open a clam. Apparently not happy with the print media attention afforded to its relative, the orange-dotted tuskfish (Choerodon anchoago) has taken the behavior to the movies … Continue reading →... Read more »

Where to put Australoithecus sediba?

by Eric in APE

It took me some time to decide what I should do with Australopithecus sediba on this Blog, in the end I decided to concentrate on the aspects I at least know a little bit of, one of them is taxonomy.I had to reconstruct a bunch of phylogenetic trees in the last few months and I found a someof free online tools which enabled me to do this without using any fancy (and expensive) Computer Programs. The only disadvantage of these resources is that they were originally made for molecular data sets. T........ Read more »

Tip of the Week: Introduction to R Statistical Software (with video)

by Mary in OpenHelix

This week’s video tip is different from our usual tips in several ways. First, you won’t hear me–this webinar was done by Heather Merk of Ohio State. We also usually highlight web-based tools, and this presentation on R statistical computing tools relies on the command line. And it’s longer than we usually do–but because of [...]... Read more »

Religious People Like Other Religious People; The Non-Religious Don’t Judge

by Eric Horowitz in peer-reviewed by my neurons

More fuel for the mindlessly intense “Who’s better, atheists or Christians?” war:

While research has shown that religious individuals are perceived as being more moral than the nonreligious, the present studies suggest that these findings are affected by in-group bias. Participants low and high in religious fundamentalism (RF) were asked to form an impression of a target’s moral and social dimensions.... Read more »

Friends with Negatives

by Radhika Takru, MA in Brain Blogger

When you meet someone for the first time, it’s only natural to assume that you’d like to put your best foot forward and leave a positive first impression. You might choose to do this by touching upon topics like your favorite music and movies. You might, if this goes well, move on to more profound [...]... Read more »

That juror is nodding—are they agreeing with me or with themself?

by Doug Keene in The Jury Room

It’s a common mistake. We see someone nodding and assume they are agreeing with us. And in the courtroom, that can be a serious error. Recent persuasion research puts even more evidence in the corner of being careful not to assume. As it happens, nodding can simply mean you are agreeing with your own internal dialogue [...]

Lace-up Ankle Braces on Injury Rates in High School Football Players

by Jeffrey B. Driban in Sports Medicine Research (SMR): In the Lab & In the Field

Ankle injuries are common in high school sports and it has been estimated that 24% of all ankle injuries among high school athletes are sustained by football players. Lace-up braces are commonly used with the goal of preventing ankle injuries. Unfortunately, there is limited data about the efficacy of lace-up braces among adolescent football players. Therefore, McGuine et al assessed whether using a lace-up ankle brace reduced the number and severity of acute first-time and recurrent ankle injur........ Read more »

Even Monkeys Can Tell Red from Grue

by Elizabeth Preston in Inkfish




Unsure of the difference between ochre and ecru? Mauve and maize? Don't feel bad, because there's at least one color distinction you can handle: warm versus cool colors. You may have thought it was made up by your art teacher to torment you, but the concept is biologically based and universal to cultures around the world. Even a monkey knows the difference.

Researchers led by Youping Xiao at Mount Sinai School of Medicine based their study, in part, on data from the World Color Survey. That ........ Read more »

Topiramate Augmentation in Major Depression

by William Yates, M.D. in Brain Posts

In which creationism threatens patients

by Björn Brembs in bjoern.brembs.blog

Republican presidential hopeful and Texas governor Rick Perry is pushing hard in support for unapproved stem-cell therapies in Texas and allegedly had such a therapy performed on himself. In this case not coincidentally, Perry is also a self-professed creationist. There are many reasons why stem-cell therapies might be dangerous, the two recently reported deaths are among the so far unidentified causes. One other, recently discovered potential risk of stem-cell therapies involves mutation and se........ Read more »

by David Winter in Careers - in Theory

A few weeks ago I wrote about regulatory focus theory (approach and avoidance motivations) and its possible impact on your career satisfaction.

Different types of goals and situations can [...]... Read more »
