Paranoia: Prevalence and Correlates

by William Yates, M.D. in Brain Posts

Clinicians dealing with psychiatric disorders commonly encounter patients with paranoia in their clinical practices.  However, it is important for clinicians to understand the relatively frequency of paranoia endorsement by people in the general population.  Whether paranoia is a pathological phenomenon commonly depends on the degree of paranoia, associated signs and symptoms and presence (or absence) of a formal psychiatric diagnosis.  Freeman and colleagues from the Institute of........

that’s not what we meant by computer scientist

by Greg Fish in weird things

A while ago, there was some buzz on the pop sci circuit about scientists using machines to catch up with the constantly growing body of published papers and asking whether the machines could ever qualify as actual scientists proposing hypotheses of their own. Now there seems to be an affirmative answer since a robot- aided [...]... Read more »

Regard thyself and put down the smoke stick

by dj in Neuropoly

As many a former smoker will probably attest, quitting cigarettes ranks high in the hard-to-kick category. I made several unsuccessful attempts before finally kicking the habit after a 10 year pack-a-day run. Ultimately what worked for me was to go cold turkey, but there were perhaps other alternatives which I might have tried. In a [...]... Read more »

Hormonal therapy and cancer – the controversy rages on

by Sally Church in Pharma Strategy Blog

Hormone replacement therapy (HRT) is one of those subjects where many have a strong opinion either way and I suspect even if we have another dozen trials evaluating at the pros and cons, those opinions won’t change very much. That … Continue reading →

How Effective is Lifestyle Management of Obesity?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Perhaps one of the most overused (and many would say ‘useless’) pieces of advise is that obesity management requires a lifestyle change.
While this may be true - there is nothing special about obesity when it comes to this recommendation, because guess what: living with diabetes requires lifestyle change, living with high blood pressure requires lifestyle [...]... Read more »

FDA Supports Compounding of Off-Label Drug to Prevent Preterm Labor

by Shaheen Lakhan in Brain Blogger

Recently, the U.S. Food and Drug Administration (FDA) approved the new drug Makena (17-hydroxyprogesterone caproate) for the prevention of preterm labor. This is the first FDA-approved drug for this indication, but the active ingredient in the drug has been a standard of care for preventing preterm labor for nearly a decade. Until now, it has [...]...

Natural selection and saving

by Jason Collins in Evolving Economics

In the academic literature at the intersection of economics and evolutionary biology, evolution of time preference (patience) is one area that has received much attention. This makes some sense, as most economic models that consider decisions over time include time preference. Time preference is normally included in the model through a discount rate of a [...]...

Mountain Dwarfs & Earthquakes

by Cris Campbell in Genealogy of Religion

Before there were materialist explanations of nature’s unpredictable fury, there were stories. These stories were not mere entertainment, but were attempts to make sense of that which was inexplicable. The world is of course an unpredictable place. We were powerfully reminded of this but one month ago, as an earthquake and tsunami devastated Japan.

A rig by any other name, could it be an artificial reef?

There are currently more than 7,500 offshore oil platforms actively probing the earth’s crust for black gold. Their relatively minimal appearance at the surface belies the shear magnitude of human construction beneath the waves. Oil platforms are among the world’s tallest man-made structures.

One Foot in Front of the Other

by Rob Mitchum in ScienceLife

There are few biological functions that we take for granted more than gait, the intricate symphony of motion that happens almost automatically when we walk or run. Gait is programmed deep into the nervous system of animals, an activity so robust that it is maintained even when large segments of brain are removed. Those crude, [...]... Read more »

This is based on a recent paper (citation below) where they identify a point mutation in the mitochondrial DNA that appears to result in hypertension.

Birds Inherited Strong Sense of Smell From Dinosaurs

by Brian Switek in Dinosaur Tracking Feathers, air sacs, nesting behavior—the earliest birds owed a lot to their dinosaurian ancestors. The first birds also inherited a strong sense of smell.

Aim Your Product Warnings at "FYI" and Not Just "CYA"

by Persuasion Strategies in Persuasive Litigator

A warning that calls attention to a product's potential danger is obviously an important part of a company's litigation prevention and defense. But according to one recent statistic, a substantial portion of the public, and potential jury pool, may be a bit cynical on the question of whether warnings are designed to educate or just provide cover. In a 2010 Decision Analysis Survey on attitudes toward products liability litigation, fully 70% shared the belief that product warnings exist to prot........ Read more »

Tales from the Intestinal Crypt

by Sanford- Burnham in Beaker

Doctors have noticed for decades that people with Down Syndrome seldom develop cancers. Down Syndrome results from an extra copy of chromosome 21, leading scientists to wonder if something about that particular piece of the genome could protect against cancer. A few years ago, researchers at Johns Hopkins University tested that hypothesis. They added several [...]... Read more »
