Gurgling or Death Rattle? Does it predict pneumonia?

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

The physical exam is an important skill for the practitioner of palliative medical arts because we may be working with patients in their home where technical diagnostic options are limited or in a treatment mode that has been defined by avoiding further diagnostic tests.  So I am particularly interested by any article that discusses clinical examination skills relevant to palliative medicine.  Of course the title did not hurt in causing me to pause.  "Gurgling ........

Holy Wars in Holy Lands

by teofilo in Gambler's House

In the year AD 1098 a spruce tree was chopped down in the Chuska Mountains, which run roughly along what is now the border between Arizona and New Mexico.  We don’t know who cut it down, exactly, since the people living in the area at the time had no system of writing and have therefore [...]...

the bottom line on hypothermia

by Michael Lombardi in a New Life in the Sea

This 2010/2011 winter has been brutally cold here in the Northeast, and unarguably colder than most. As time has passed over the years, it's become harder and harder to jump in the water this time of year. But, therein lies no choice if one is to continue working as a diving contractor in New England. There is nothing pleasant about it, and all you can do is plan well in advance for the elements.

For the majority of the winter months, say late November through early March, we use hotwater suits........ Read more »

No, Bounce Fabric Softener will NOT protect you from bugs

by bug_girl in Bug Girl's Blog

I usually like Lifehacker, but in this case, FAIL.  Here’s a story they ran 2 weeks ago: Bounce Fabric Softener Keeps Mosquitoes and Gnats Away Some people have sworn by the power of Bounce dryer sheets—and specifically Bounce, too—to keep mosquitoes away from them, and gnats out of their garden. Now scientists have proven the [...]... Read more »

An evolutionary explanation of consumption

by Jason Collins in Evolving Economics

Since Thorstein Veblen’s 1899 book Theory of the Leisure Class, the economics profession has taken a somewhat mixed approach to consumption. In areas such signalling theory, Veblen’s argument that conspicuous consumption must be wasteful and expensive to be a reliable signal of wealth is well recognised. Conspicuous consumption has a purpose as a signal. However, [...]... Read more »

Psychology’s Frenemies

by Jenika in ionpsych

It’s a lot like watching a reality television show, only without Simon Cowell providing amusing commentary.  But the essential ingredients are all there: shifting alliances, suspicions, competition for resources, and perhaps even frenemies.  Yes, watching neuroscience interact with clinical psychology … Continue reading →...

Uganda’s 2006 Plague Outbreak

by Michelle Ziegler in Contagions

People are sometimes surprised to learn that the plague still exists today. They ask me why they  have never heard about it in the news.

Weekend Short Stories

by Matthew DiLeo in The Scientist Gardener

Some pretty cool links for your weekend:

Jurassic Park beer:

Fossil Fuels Brewing Co. makes beer with an Eocene-era yeast, formerly encased in a 45 million year old chunk of amber! Incredible, but apparently true. Viable Bacillus spores were discovered first in 25-40 million year old amber by Raul Cano (these spores are so tough you can't kill them with an autoclave). He then founded a startup (Ambergene) with the hopes of discovering ancient antibiotics (this was back during the natural ........ Read more »

Did Intestinal parasites and poor hygiene protect us from autoimmune diseases?

by ABK in Environment and Health

Autoimmune diseases are troubling, and often frustrating and painful for health care practitioners and patients. As far as I know, celiac disease is the only autoimmune disorder with a specific and identified trigger: the protein gluten. It has also been pointed out that the incidence of Celiac Disease, the formal name for gluten-triggered autoimmune reactions in the bowel, appears to have been increasing. Some have claimed that humans are not adapted to consumption of plant proteins like glu........ Read more »

When "Healthy Brains" Aren't

by Neuroskeptic in Neuroskeptic

There's a lot of talk, much of it rather speculative, about "neuroethics" nowadays.But there's one all too real ethical dilemma, a direct consequence of modern neuroscience, that gets very little attention. This is the problem of incidental findings on MRI scans.An "incidental finding" is when you scan someone's brain for research purposes, and, unexpectedly, notice that something looks wrong with it. This is surprisingly common: estimates range from 2–8% of the general population. It will hap........ Read more »

Transparency

by Janet Kwasniak in Thoughts on thoughts


Thomas Metzinger wrote an outline of his book, ‘Being No One’, which puts his theory of consciousness in a very brief, compact form. He puts forward a list of constraints that any system must have to be conscious. The first three constrains gives a simple form of consciousness which he then elaborates with further constrains.

Kinky evolution: did we evolve from PVC?

by Gemma Atkinson in Protein evolution and other musings

PVC may have played a big part in our evolution... But, no I'm not talking about polyvinyl chloride (sorry to dissapoint!), I'm talking about the Planctomycetes, Verrucomicrobia, Chlamydiae (PVC) bacterial superphylum. And I'm talking waaaay back, when the Chlamydiae were much more innocent and hadn't got into that whole sexually transmitted disease scene.In a Science article, Devos and Reynaud discuss the possibility that that The PVC bugs, which appear to be a monophyletic group forming their ........

Can’t sleep? Why taking the Blue Pill is Best! (Unless you’re an Italian man)

by Stuart Farrimond in Dr Stu's Science Blog

Insomnia is something all of us struggle with from time to time. Not being able to get off to sleep is perhaps one of the most frustrating and loathsome things in the world (second only to an itchy back).

Many of us resort to herbal or medical remedies. If you had to choose one, which would you go for? Did you realise though that the colour of your remedy has an effect!? Read on to find out why blue is best…... Read more »
