Teen Driving and Fatal Crashes

by William Yates, M.D. in Brain Posts

Reducing motor vehicle accident rates and deaths in the teenage population is a public health priority.  Efforts to reduce the rates of fatal injuries in young drivers include graduated driving license privileges and reduced legal blood alcohol for teen drivers.  States have variable legal BAC generally any level or a level below 0.01 or 0.02 g/dL compared to .08 to 1.0 g/dL for adults.  Additionally, the hazard related to using a telephone and texting while driving is significant........

Is My Child Behind in His Development?

by Brandon in Notes on Parenting

By BrandonDevelopmental Milestones: Fact or Myth?As parents, we are almost constantly comparing our child to someone else's child (or even to our own children who have already gone through that phase of life), and there always seems to be something to fret about. Are you worried that your child isn't saying enough words yet, or isn't walking and he's already a year old? These are common concerns, especially for new parents.

In my undergraduate and graduate training (and as a parent) I have lear........ Read more »

Leading by Design

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Is there consensus about the role of product design as the leading function in the supply chain? Not yet! This article introduces the topic of integrating decisions in product and supply chain design and gives a short glimpse on the "how to implement" part.

Case study
During the last weeks I conducted the following case study on the impact of product design on supply chains using literature and expert interviews, looking for an answer to the basic question: What are the advantages of integ........ Read more »

The Evolutionary Roots of Talking With Our Hands

by Krystal D'Costa in Anthropology in Practice

Human and bonobo ape hands. © SPL

New Yorkers are hand talkers—we often use gestures to add emphasis to our conversations. Whether we're pointing to direct tourists, or waving to demonstrate our exasperation with traffic, drivers, or pedestrians, or trying to interject (New Yorkers don't interrupt!) we're gesticulating. We're not the only ones to do this, of course, but in my experience we do tend to employ this element of communication fairly frequently.
The role of gestures in communicat........ Read more »

Can Arsenic Replace Phosphorus? One Bacterium Says “Yes”

by A. Goldstein in WiSci

Up until a few days ago, scientists believed that all life forms on Earth were composed of six elements: carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus. Then, on December 2, 2010, NASA researchers made a discovery that forced scientists everywhere to reconsider this belief: a bacterium that can replace phosphorus with arsenic.1 Typically, arsenic is [...]...

Searching for scientific abbreviations

by sciencebase in Sciencebase Science Blog

Ambiguous abbreviations and acronyms are annoyances when it comes to text search and data mining. As a writer-editor, I was always taught to spell out the long form (LF) of a short form (SF) at first mention in a document so that the reader would know that when I mentioned EBV I was referring to [...]Searching for scientific abbreviations is a post from: Sciencebase Science Blog

non-Traditional family structures and genomics

by Trey in OpenHelix

As I and my family await our 23andme kit to scan our genomes, family history has come back to the forefront of my thoughts. I used to be very fascinated by my own genealogy, and with adopted children, the concepts of descent, biology and culture have taken adjusted meanings for me. It’s why we have a ‘family map’ instead of a ‘family tree’. The difference between our cultural genealogy and our genetic genealogy has been become quite clear to me. Obtaining our family........

Your yawns and your dogs

by Zen Faulkes in NeuroDojo

In humans, yawning is contagious. Heck, I’ll bet just looking at the title and first sentence of that post triggered a couple of yawns somewhere in the blogosphere.

A couple of years ago, a report that dogs could “catch” the yawns of their human owners made a big splash in the news media. Here’s a particularly provocative headline:

Dogs ‘may be able to read their owner’s minds’
When you yawn, and then I yawn, you know that I am reading your mind.

While the headline is over the t........ Read more »

Is the Future Bisexual?

by Shaheen Lakhan in Brain Blogger

Last week, I heard a girl on the radio, who was talking about how she would have no problem doing a threesome with another girl, if her boyfriend desired it. The girl’s carefree attitude, revealing to hundreds of thousands of strangers that she was open to a bisexual experience reminded me of a certain 2005 study [...]... Read more »

Sedentary Physiology Part 1 – Not Just The Lack of Physical Activity

by Travis Saunders, MSc, CEP in Obesity Panacea

Image by kaibara87
Welcome to our 5-part series delving into the fascinating research being performed in the emerging field of sedentary physiology.  Today, we’ll start with an introduction.
As regular readers will know, sedentary physiology is one of our favourite topics here at Obesity Panacea.  Later this week we will be examining the relationship between sedentary behaviour (aka behavior) and health, as well as the mechanisms that are thought to mediate this association.  But before we ........

Amiodarone for Cardiac Arrest in the 2010 ACLS – Part III

by Rogue Medic in Rogue Medic

The research only demonstrates improved survival to admission, as if that does anything more than provide false hope and huge hospital bills. Why do we base the standard of care on such limited research?

Since there is no new amiodarone research, let's look at the old surrogate endpoint research that compares amiodarone with placebo. Keep in mind that this surrogate endpoint study is the basis for over a decade of still unproven treatment.... Read more »

Article review: Consensus methodologies in qualitative research

What types of methodologies are used to develop a consensus statement? I'm in the midst of helping to write a consensus statement manuscript in education and ran into this great review article. It's from the British Medical Journal in 1995. Basically, there are 2 general types of methodologies:Delphi ProcessNominal Group Technique Delphi ProcessAn example of a consensus topic might be: How will patient care be affected by the new ACGME Duty Hours rules?

How marsupial embryos develop (a short story)

by Captain Skellett in A Schooner of Science

Marsupials are just plain weird when it comes to procreating. I’m not talking about bifurcated penises (where the penis has two heads) although that’s pretty freaking weird. I’m talking about the embryos. When a baby marsupial is born after a 4-5 week gestation, it’s a tiny pink speck of nothing much. About the same size [...]... Read more »

Unquestioning dogma: the gatekeepers of science

by Björn Brembs in

This morning my friend Ramy reminded us of the recent spats over PLoS One publications (Darwinius, Red Sea) and how they were used to question the 'reputation' of PLoS One as a journal. Of course, it is about as meaningful to talk about the reputation of a journal as it is to talk about the reputation of the cover of a book. Journals are containers which say very little about their content. But on to the really relevant point:Specifically, Ramy pointed out how the current spat about a publicati........ Read more »

Blog: Qubits and Crypto

by Torah Kachur, Rheanna Sand and Brit Trogen in Science in Seconds

Secrets and lies define the government and military, that and being led by bumbling fools.  There is no doubt that some military information should be kept secret like technological advances, battle locations and strategies and George W. Bush's IQ.  For secrets to be kept away from Wikileaks, cryptography is essential.  The new type of cryptography that is being tested by the US military research division, DARPA, is quantum cryptography.  Because if codes like DaVinci&........
