The worm in sheep’s clothing

by Wellcome Trust in Wellcome Trust Blog

Good news for sheep: scientists have moved a step closer to understanding how a disease-causing worm evades the sheep immune system. Parasitic gastroenteritis (PGE) causes diarrhoea, weight loss and dehydration in sheep and can be fatal. The disease is commonly caused by a nematode worm, Teladorsagia circumcincta, which makes its home in the stomach of [...]... Read more »

Ocean of Pseudoscience: Sharks DO get cancer!

by Christie Wilcox in Observations of a Nerd

The sea is a dark and often mysterious place, and it's no wonder that the fear and fascination with the marine world has led to more than a few inaccurate claims. The crew over at Southern Fried Science have decided that this week is all about busting pseudoscience and the myths that surround our ocean realm. As it turns out, I'd posted about one of these before. So here, in honor of Ocean of Pseudoscience week, is a repost busting the myth that sharks don't get cancer.

There are a lot of myths........ Read more »

Why are Zipfian distributions found in language?

Article Review: Student documentation in the chart

by Michelle Lin in Academic Life In Emergency Medicine

Do you have medical students rotating in your Emergency Department? Are they allowed to document in the medical record?Charting in the medical record is the cornerstone of clinical communication. You document your findings, your clinical reasoning, and management plan. The medical record allows communication amongst providers.

Grab it, bag it, bin it - a new approach to psychological problem solving

by BPS Research Digest in BPS Research Digest

If something's troubling you, write it down, put it an envelope and seal it. Doing so will help bring you psychological closure. Xiuping Li at NUS Business School asked 80 students to write about a recent decision they regretted. Half of them were then told to seal their written recollection in an envelope. Afterwards, the envelope students felt less negative about the event than control students who just handed in their recollection without an envelope. The finding was replicated with forty fem........

Limbaugh/Palin "death panels" extend the lives of terminally ill patients

by The Neurocritic in The Neurocritic

What is palliative care? Until quite recently, it's something I haven't given much thought. Although there was a highly regarded article on hospice and palliative care by Atul Gawande in last month's New Yorker, I didn't read it or think it applied to my life. All that changed less than two weeks ago, when my father was hospitalized in critical condition after collapsing. First he went to the ER, then the transitional ICU, and finally he was placed in the palliative care unit by the time I arriv........ Read more »

The lost world – freshwater biodiversity conservation

by CJA Bradshaw in ConservationBytes

Even the most obtuse, right-wing, head-in-the-sand, consumption-driven, anti-environment yob would at least admit that they’ve heard of forest conservation, the plight of whales (more on that little waste of conservation resources later) and climate change. Whether or not they believe these issues are important (or even occurring) is beside the point – the fact that [...]... Read more »

Do the Chaco Effigy Vessels Portray Kachinas?

by teofilo in Gambler's House

One noteworthy thing about George Pepper’s interpretations of the effigy vessels found at Pueblo Bonito is his attempt to link them to specific Hopi kachinas.  He does find a general similarity in facial and body decoration between one of the partial vessels, found in Room 38, and one kachina and notes at the end of [...]...

Science Blogging Meta

I love the Groth and Gurney paper, and not just because it introduced me to The authors analyzed 295 blog posts about chemistry and the included citations. In comparison to the usual pieces which deal with science blogging in the scholarly literature, this paper has dealt with a large number of posts.

Many Children Still Haven't Recovered from Katrina

Now, five years later, there's new evidence of the significant, negative impact of Hurricane Katrina on children's mental health. The study "Children as Bellwethers of Recovery" was conducted by researchers from the National Center for Disaster Preparedness at Columbia University's Mailman School of Public Health and was published online by the Journal of Disaster Medicine and Public Health Preparedness.

The results come from a longitudinal study of 1079 families in Louisiana and Mississippi ........ Read more »

No turning back for science

by Zen Faulkes in NeuroDojo

An article with a title like “Science’s dead end” seems like an active effort to troll the science blogosphere. Maybe author James Le Fanu has a point, but a quick search raise doubts as fast as you can type. He’s trained as a medical doctor, not a researcher. And he seems to be a cynical one, having written a piece with a similarly apocalyptic title, “The fall of medicine,” for the same magazine over ten years ago.

He outsider’s perspective is apparent in his first paragraph.
