More on Phoneme Inventory Size and Demography

by Wintz in A Replicated Typo 2.0

On the basis of Sean’s comment, about using a regression to look at how phoneme inventory size improved as geographic spread was incorporated along with population size, I decided to look at the stats a bit more closely (original post is here). It’s fairly easy to perform multiple regression in R, which, in the case of . . . → Read More: More on Phoneme Inventory Size and Demography... Read more »

Listeria's Visiting Card

by Moselio Schaechter in Small Things Considered

by Elio

During infection, host and parasite carry out repeated and intense conversations that often rise to the level of shouting matches. The language they use is chemical, the words and sentences eloquent and forceful. Eavesdropping on the conversation between Listeria monocytogenes LINK 5 and immune cells of its host, Portnoy and colleagues LINK 1 discovered an intriguing linguistic use for a novel “second messenger,” cyclic-di-AMP (c-di-AMP).

It has been known that Listeria, like man........ Read more »

Repost: Premenstrual syndrome: understanding origin and variation

by Kate Clancy in Context & Variation

I am reposting some of my LEE blog posts over here to highlight some of my research blogging. Hope you enjoy the ladybusiness anthropology!If you are female and post-menarcheal (that is, you’ve had your first period), you have probably had at least one person tell you that you are PMSing – either jokingly, or with an unpleasant edge. You may have expressed anger or irritability; you may have simply stood up for yourself. Or, you may have no idea what prompted the statement.Maybe you were ang........ Read more »

Mechanisms of castration resistance in prostate cancer

Greenwashing – Is there really a sustainable Orange Roughy fishery?

by Southern Fried Scientist in Southern Fried Science

Wandering through the grocery store the other day, I noticed something strange in the fish bin. Now, in general I’m pretty conscious of where my fish comes from, how it was caught, whether the fishery as a whole or the specific population is sustainable. I pay attention to those details and I can usually tell [...]... Read more »

Nintendo Wii – Is It Really Physical Activity?

by Travis Saunders, MSc, CEP in Obesity Panacea / CC BY 2.0

Earlier this year, Peter wrote a post about Wii-related injuries which generated some interesting discussion.  Essentially, some readers felt that we were being too hard on the Wii, with one commenter going so far as to suggest that the post was “anti-Wii” (hard to dispute, given that the post was focused on Wii-related injuries!).  Although we’ve mentioned the Wii in passing on Obesity Panacea before, we’ve never ........

Dissecting lions and tigers: Inside Nature's Giants series 2, part III

by Darren Naish in Tetrapod Zoology

I hope everyone has been enjoying my write-ups of Inside Nature's Giants (ING), series 2 (for comments on episode 1 go here, and for thoughts on episode 2 go here). Time to look at ep 3: the big cat one.

Given that big cats are more popular (among the general populace) than are either sharks or snakes, it's predictable that this was the most discussed, most anticipated episode. Like the others, it was excellent [adjacent image © Windfall Films/Channel 4].

And let me say again how good th........ Read more »

Autism Evident in Newborns

by Shaheen Lakhan in Brain Blogger

The prevalence of autism spectrum disorders (ASDs) has increased by nearly 10-fold in the last 2 decades, owing, in part, to earlier diagnosis by community practitioners. Now, a new study in the September 2010 issue of Pediatrics reports that signs of autism may be present as early as 1 month of age. Researchers evaluated children [...]... Read more »

THIS Is Why I Love the Mediterranean Diet

Italian researchers reviewed the medical/nutrition literature of the last three years and confirmed that the Mediterranean diet 1) reduces the risk of death, 2) reduces  heart disease illness and death, 3) cuts the risk of getting or dying from cancer, and 4) diminishes the odds of developing dementia, Parkinsons disease, stroke, and mild cognitive impairment.

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.

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. Chart documentation is a crucial skill that every medical student should know, as stated by the Association of American Medical Colleges (AAMC). However, there is a growin........ Read more »

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 »
