Cold weather limits potential range of Burmese python invasion

by Rob Goldstein in Conservation Maven

The well-publicized invasion of Burmese pythons in the United States is unlikely to spread farther north than south Florida according to a new study by scientists from the National Wildlife Research Center...... Read more »

French – the brand

by Ingrid Piller in Language on the Move

Installment #6 in the mini-series on multilingual signage
Multilingualism sells! Some forms of multilingualism that is. In the world of marketing, languages operate like brands: they are a signifier for something else but they are devoid of substance. To phrase it in Marxist terminology: the exchange value of languages has in some contexts come to overshadow [...]... Read more »

The Neurogenesis theory of depression and a little guy called CREB

by Evil Monkey in Neurotopia

Sci wishes she could begin this post with something clever. But she has a cold. Suffice it to say that this paper is cool and interesting. And also, as Sci has a cold, I expect all of you to read this post out loud to yourselves in suitably stuffy, gluey Sci-voices.

a possible link between pesticides and ADHD

by Tal Yarkoni in citation needed

A forthcoming article in the journal Pediatrics that’s been getting a lot of press attention suggests that exposure to common pesticides may be associated with a substantially elevated risk of ADHD. More precisely, what the study found was that elevated urinary concentrations of organophosphate metabolites were associated with an increased likelihood of meeting criteria for [...]... Read more »

Atlatls to Bows: A Very Strange Atlatl from Washington State

by teofilo in Gambler's House

Sometime in the early 1950s a wooden object was dredged from the mouth of the Skagit River, north of Seattle.  It ended up in the possession of Mr. and Mrs. Edwin Johnson, residents of the nearby town of La Conner.  In 1952 the Johnsons showed it to two local archaeologists, Herbert Taylor of Western Washington [...]...

Evidence-Based Health Law Calls for Measured Laws

by Paul Statt in Paul Statt Communications

How can you measure the impact of a law? The Obama administration, for example, recently called for an “evidence-based” approach to the writing of laws and policies that affect the public’s health in matters of drug abuse. But applying the scientific method to an evaluation of a law’s impact requires a rigorous approach to measurement. In “Measuring Law for Public HealthEvaluation Research,” published in the June 2010 Evaluation Review, Charles Tremper, Sue Thomas and Alexander C. Wa........ Read more »

Applying Reliability Theory to Aging

by Reason in Fight Aging!

Reliability theory is, put very simply, a way of modeling and predicting the failure modes and mean time to failure of complex systems with many redundant parts subject to wear and tear. Reliability theory has seen a great deal of use in the electronics industry, amongst many others, but the human body is also a complex system that can be considered in these terms. Looking at our life spans and age-related illnesses in the context of reliability theory and the accumulating failure of redundant s........ Read more »

Dopamine, Mental Illness and Creativity

by Maria P. in noustuff

A new study by researchers at the Swedish medical university Karolinska Institutet supports the hypothesis that there is a link between mental illness and creativity. More specifically, they showed that highly creative people – with high scores in divergent thinking – had a lower density of D2 receptors in their thalamus than less creative people. [...]...

The incredible leaf-tailed geckos (gekkotans part V)

by Darren Naish in Tetrapod Zoology

Before I start, allow me to announce that Tet Zoo merchandise is now available! So far, I've only used the Tet Zoo logo for these products, but I might produce additional designs in time.

Anyway... welcome to another article in the Tet Zoo gekkotan series. I really want to get through to the end without too many distractions (like amphiumas, wayward grey whales, manatees, white rhinos, giraffe-necked tortoises), otherwise I might never finish. Look what happened with toads and temnospondyls........ Read more »

Bycatch Claims Sea Turtles By the Millions

by Scott A. in Thriving Oceans

It’s an article packed full of potential contention as it speaks to a variety of issues involving fisheries management.  So thank God we are dealing with a charismatic marine species or we just may be contemplating their extinction.  But then again, perhaps we are doing just that since all 7 species of marine turtles are [...]...

Ghrelin after Gastric Banding vs. Sleeve Gastrectomy

by Maureen McCormick in GourMind

In the last post, we discussed differences in ghrelin production after gastric bypass and sleeve gastrectomy. Today the studies we are going to consider describe the effects of gastric banding and sleeve gastrectomy on ghrelin and weight loss variables.Langer et al. randomly assigned (love it!) 20 patients to either gastric banding or sleeve gastrectomy. The groups were well-matched on demographics and medical co-morbidities. The researchers measured plasma ghrelin levels at 4 time periods: preo........ Read more »

Will the financial crisis turn people to religion?

by Tom Rees in Epiphenom

Well, we have a global financial crisis. We also know that religion is a source of solace for a lot of people. So will the financial crisis mean boom times for religion?

The answer is probably yes, but not in a way that's straightforward. That's the message from two new studies, one in the US (which is the topic of this post) and one in Indonesia (which I'll write up in the next post). The Indonesian one is particularly interesting because it's not often we get insights into the role of religi........ Read more »

Personal Genomics, tipping points and a personal perspective

by Trey in OpenHelix

Please indulge a long post from a personal perspective, what genomics is about to do for _me_. This is information that many, if not all, of our readers already know. I’ve been researching and working in either experimental biology or genomics for over 20 years. Ever since the beginning of the Human Genome Project , which coincidently started the same year I started my Ph.D. program, into my postdoctoral research at EMBL and now my work at OpenHelix, I’ve known that someday personal........

Here today, gone tomorrow!

by John Carroll in Chronicles of Zostera

A complete and utter failure? You decide. Last fall I had the bright idea to track overwinter survival and subsequent spring conditioning for scallops released in different habitats (eelgrass - their preferred habitat, see Thayer and Stuart 1974; Codium fragile - an introduced macroalgae which we think might serve as a suitable alternate substrate in the absence of eelgrass; and unvegetated, as a baseline for comparison). I have examined these habitats for growth in juvenile scallops and have ........ Read more »

How Chefs think about Size - Portion Size that is (another b2d nugget)

"Despite the focus on the increase in portion sizes and the possible role in the development of obesity, little is known about how portion sizes are determined in restaurants." This is how an intriguing discussion of Chefs and their restaurant food size practices begins. The study aslo notes that eating out has gone up from 2.3x's a week in 1981 to 5 times in 2000.

Google Flu Trends is not accurate

by Vincent Racaniello in virology blog

Google Flu Trends uses analysis of large numbers of search queries to track influenza-like illness in a population. The idea is that the frequency of certain queries correlates with the percentage of physician visits in which a patient presents with influenza-like symptoms. Google claims that it can accurately estimate the level of weekly influenza activity [...]... Read more »

Time-Space Compression in the Digital Realm

My work on time in the digital realm is coming slowly but surely. At the moment I'm thinking of multiple temporalities and the ways in which we occupy these dimensions while adhering to standardized time. Birth (2007) explores these issues with an article that deals with the conflicts that can arise out of a meeting of biology, clock, sun, and sociality. Birth raises a point in particular that

Structural differences between Marburg and Ebola viruses

by epibio in EpiCentral

Ebola virus (EBOV) and Marburg virus (MARV) are related pathogens that cause hemorrhagic fevers. In many cases, viral infections are fatal. Both viruses are native to Africa where outbreaks have been occurring for decades. There is no effective therapy for the hemorrhagic fevers caused by these viruses. EBOV and MARV are in the same taxonomic family and are structurally identical; however, they elicit different antibodies. Enterlein et al.* used the AmpliScribe™ T7 High Yield Transcription Kit........ Read more »
