Did I mention that Caperea is really, really weird? [Tetrapod Zoology]

by Darren Naish none@example.com in We Beasties

The recent discussion of Caperea's skeletal morphology (Caperea = Pygmy right whale) inspired Joy Reidenberg to send these photos of a Caperea skeleton, taken in New Zealand and used here with her permission.





In this view of the whale's thoracic region (we're standing beneath the whale, looking up into its ribcage), you can see that the transverse processes (the wing-shaped structures that project from both sides of each vertebra) are proportionally huge: so big that many of them overlap. ........

Dietary nitrate ameliorates metabolic syndrome in mice

by Colby in nutsci.org

I became interested in nitrate because early studies have been consistently showing that it may improve exercise performance by lowering the oxygen cost of exercise, and this research is in humans.  Reading through other literature, it seems there is a paradigm … Continue reading →... Read more »

Should you try online jury research?

by Rita Handrich in The Jury Room

I mean really. How do you know who is out there as your sample mock jury? There are a number of companies offering online jury research these days. And, as they say, it’s cheaper, it’s fast, and it gives you a window into the potential reactions to your case. Obviously, we have some bias about [...]

This week, I am attending a Scientific Symposium called “Recovery From Addiction“, organised as part of the Alberta Family Wellness Initiative of the Norlien Foundation. My interest in this meeting (where, for once, I am not a speaker on the program), comes from the close links between mental health, addictions and obesity that I regularly [...]... Read more »

Today is Hagfish Day! Who knew?
What is a hagfish?
Hagfish are primitive eel-like chordates make famous for their relative unattractiveness*, profuse production of slime, and charismatic ability to tie themselves in knots. They are perhaps the only ‘fish’ that possesses a skull, but no vertebral column. But the question “What is a hagfish?” goes [...]... Read more »

Number Needed to Ban: a new tool for calculating the benefits of banning particular dog breeds

by The Dog Zombie in The Dog Zombie

A study published this month in the Journal of the American Veterinary Association (JAVMA) takes on the issue of whether breed-specific legislation (BSL) is effective. BSL is a tool used by some communities to attempt to reduce injuries from dog bites. The idea is that particular breeds of dogs are responsible for more than their share of injuries, so banning or otherwise controlling those breeds will result in a reduction in injuries. The group of breeds collectively known as “pit bulls” re........ Read more »

The Matthew Effect Strikes Again

by Hadas Shema in Information Culture

The new Bornmann, de Moya Anegón and Leydesdorff paper, published in PLOS ONE, shows that highly cited papers tend to reference other highly cited papers more often. That is true especially for the life science and health science disciplines. Ms. Corbyn from Nature News saved me the need to summarize the paper by writing an excellent article about it. Based on their findings, Bornmann et al. suggested to concentrate funding on already highly-cited researchers and research groups ("A concentrati........ Read more »

Trick of the trade: Face mask ventilation in edentulous patients

by Michelle Lin in Academic Life In Emergency Medicine

Can you imagine trying to bag-valve-mask ventilating this patient without teeth? Edentulous patients can cause BVM problems because air tends to leak out the sides of the mouth, because the cheeks don't contact the mask as well. You can do a jaw-thrust and/or place an oropharyngeal airway to help. What else can you do?Trick of the trade:"Lower lip" face mask repositioningReposition the mask more superiorly to improve the BVM seal. Normally the inferior edge of the mask sites between the lower li........ Read more »

You Read It Here First...Again

by Neuroskeptic in Neuroskeptic

A couple of months ago I pointed out that a Letter published in the American Journal of Psychiatry, critiquing a certain paper about antidepressants, made very similar points to the ones that I did in my blog post about the paper. The biggest difference was that my post came out 9 months sooner.Well, it's happened again. Except I was only 3 months ahead this time. Remember my post Clever New Scheme, criticizing a study which claimed to have found a brilliant way of deciding which antidepressan........ Read more »

Attitudes and beliefs of trainee probation officers: A ‘new breed’?

Speakers with a foreign accent are perceived as less credible - and not just because of prejudice

by BPS Research Digest in BPS Research Digest

Speakers with a foreign accent are perceived as less believable than native speakers. A new study shows this isn't just because of prejudice towards 'outsiders'. It also has to do with the fluency effect, one manifestation of which is our tendency to assume that how easily a message is processed is a mark of its truthfulness. The effort required to understand an accented utterance means that the same fact is judged as less credible when uttered by an accented speaker, compared with a native spea........ Read more »

Critical mass or is mass critical?

by Shaun Hendy in A Measure of Science







In research and development, it’s often taken for granted that teams require a certain critical mass to be successful.  Indeed, in a recent paper [1] two European researchers claim to have seen the effects of critical mass in the UK Research Assessment Exercise (RAE) and its French equivalent (HT: Mark Wilson).  However, I think that [...]...

How Prozac works

by Shaheen Lakhan in Brain Blogger

The tightly regulated balance between secretion and removal of neurotransmitters is not functioning properly in certain mental conditions like bipolar disorder, obsessive-compulsive disorder, anxiety, and depression. Neurotransmitters are signaling molecules used to transmit messages between neurons (nerve cells) in the brain. Serotonin is one of the neurotransmitters affected in depression and similar disorders. The most common class of [...]... Read more »
