2010 in review: Aging brains, money, happiness, and a bris exception

by Doug Keene in The Jury Room

As trial consultants, we are always on the lookout for new nuggets of useful information. Some of them are true wisdom and some… let’s just say ‘not so much’. Generally, we share only the really good stuff with you but sometimes we regress a bit. And this is one of those times. Hang on! Despite [...]

Asymptomatic Sustained Ventricular Fibrillation in a Patient With Left Ventricular Assist Device

by Rogue Medic in Rogue Medic

This patient is pulseless. Pulseless patients are not rare. A 911 call for a pulseless patient is usually because the pulseless patient is dead.

Contrariwise, a patient talking to me has a pulse. I have had several patients who were awake and talking, but without any palpable pulses. The absence of palpable pulses is different from the absence of pulses. All of these patients, with no palpable pulses, were significantly symptomatic.... Read more »

World's Largest Snake Threatened with Extinction by...Hikers and Backpackers?

by David Steen in Living Alongside Wildlife

   Imagine my surprise and interest when I noticed a newspaper article about an anaconda population crash in Bolivia.  Anaconda's are the world's heaviest snake and these impressive animals can be found swimming through the swamps of South America (not Alabama).  Although just about everyone has heard of anacondas, it's not a species we know too much about.  Some anacondas live in a grassy ...

Triclosan induces hypothyroidism and is transfered to infants during lactation.

by ABK in Environment and Health

Triclosan is used in many personal care products as an anti-bacterial agent. You can find it in soaps, toothpaste etc. It is also an endocrine disruptor that effects at least two different (albeit interrelated) systems. Triclosan has some estrogenic effects, Paul et al. (Dec 2010) and has also been shown to alter thyroid hormone levels early in lactation. Thyroid hormones are especially important during fetal and infant development because they play crucial roles in brain development. Early........ Read more »

Burrowing Owls Embark on Cross-Continent Migration

by Scott A. in JournOwl

I’ve definitely been neglecting my journal reading over the last few months, and if I want to be honest it’s probably more like a 6 month hiatus.  As I returned from a field visit in Winters, California, I got the itch to see what’s up with the latest in raptor research.  And the little voice [...]...

The Effects Of Special Relativity On Planetary Orbits.

by Joseph Smidt in The Eternal Universe

General relativity affects the orbits of planets in ways Newtonian gravity cannot account for. Interestingly, Lemmon and Mondragon explore if special relativity can account for the same behavior predicted by general relativity.   They find that qualitatively it can, but quantitatively it comes up a little short and so the full general relativistic treatment is still needed.

First a reminder:

specific inhibition of nonsense-mediated mRNA decay by small molecule

by Vasili Hauryliuk in stringent response

The last step of protein synthesis is called translation termination. During this step the stop codon is recognized by the protein factor called "release factor" and finished protein is cleaved off the tRNA. Mutations which cause premature termination (nonsense mutations) lead to shortened protein which is usually defective, and in order to avoid accumulation of these proteins such mRNA are recognized by nonsense mediated mRNA decay (NMD) machinery and degraded.This is usually a good thing, but ........

How Much Pain is Our Kid Feeling? Well, How Much Can We Afford?

by David Berreby in Mind Matters

When a sick kid is too young to speak, doctors naturally ask a parent or other caretaker how much it hurts. Only half of the answer, according to this study in this month's Journal of Pain, is based on symptoms. The rest arises from the adult's own life experience, including social class: Given a ...Read More

The geography of Food vs. Forests

by Paul Spraycar in Beyond Climate Change

To answer the question of how to meet the food and fuel needs of a growing, increasingly prosperous human population without cutting down the world’s forests in the process, a research team literally drew a map of carbon stocks and crop yields for the entire globe. Based on the “strong differences in the carbon-crop tradeoff among regions,” increasing yield on existing tropical croplands is preferable to clearing new land. The authors used maps of crop distribution and average yields, toge........ Read more »

Fluoride and IQ
