Why ‘chavvy’ external illuminated Christmas displays are embraced by the working class

by SAGE Insight in SAGE Insight

Illuminations, class identities and the contested landscapes of Christmas From Sociology In the last two decades, illuminating the outside of a house with multi-colored lights has become a popular British Christmas practice. Whereas in the US these illuminations typically cover large middle-class homes, in Britain they have been largely adopted within working-class neighborhoods.  This article investigates [...]...

Holidays & weight gain: what the science suggests

by Colby in nutsci.org

Many people have the perception that they are likely to gain 5 or 10 pounds during the holiday season (Thanksgiving to after New Year’s Day).  This myth has been propagated by media (4), perhaps partially explaining why it exists.  But … Continue reading →... Read more »

How Strong Are Your Relationships? Drop a Few Mails Into This Analyzer, and Get an Estimate

by David Berreby in Mind Matters


"Most people are other people," Oscar Wilde wrote. "Their thoughts are someone else's opinions, their lives a mimicry, their passions a quotation." You get the feeling, somehow, that he thought this was a bad thing. Seems likelier that it's just an inevitable fact about a species whose members ...Read More

Ergot in the Rye

by Matthew DiLeo in The Scientist Gardener

Stopping at the charity field on the way back from pollinating, I noticed a ripening rye cover crop the next field over - and decided to look for my friend, ergot.*

I couldn't believe my luck! There were little black pods sprouting from rye spikes all over the edge of the field. This is a very exciting creature to a plant pathologist - and one that's had quite an impact on European history...


Ergot is a plant disease caused by Claviceps purpurea, a member of one of my favorite fungal families........ Read more »

There are two species of African elephant

by Greg Laden in Greg Laden's Blog

Everyone knows that there are two kinds of elephants in this world: Asian and African. The Asian is the only one that can be trained and the African ones live in harmony with their environment until hunters come by and shoot them. Scratch a little deeper, and the African bush elephant lives by destroying its environment and moving on to new areas, where it destroys that environment, cycling back to the original region over generational time; Both African and Asian elephants can be trained; and........

Crucifixion, by Francis Bacon (1933).Crucifixion (1933) (oil on canvas) was subsequently purchased by Sir Michael Sadler (who, other than friends or relations, was the first to buy a painting), and who also commissioned a second version, Crucifixion (1933) (chalk, gouache and pencil), and sent Bacon an x-ray photograph of his own skull, with a request that he paint a portrait from it.

What Mirror Images and Foreign Scripts Tell Us About the Reading Brain

by Livia Blackburne in A Brain Scientist's Take on Writing

Here’s a simple exercise. Count the number of times the letter ‘A’ appears in the sentences below. Easy enough, but, there's a catch. You have to do it without reading the words.

Ready?

Is XMRV a laboratory contaminant?

by Vincent Racaniello in virology blog

Since the first observations that the human retrovirus XMRV is associated with prostate cancer and chronic fatigue syndrome (CFS), new studies have been carried out to determine the role of the virus in these diseases. The results have been conflicting: XMRV (and related retroviruses) have been found in some patients, but not in others. Whether laboratory contamination [...]... Read more »

Pass the Salad, Please: Many Theropods Ate Plants

by Brian Switek in Dinosaur Tracking

Coelurosaurs were one of the strangest groups of dinosaurs. In addition to the famous predators Tyrannosaurus and Velociraptor, the coelurosaurs included the small, fuzzy Sinosauropteryx; “ostrich-mimics” such as Struthiomimus; the long-necked, sickle-clawed giant Therizinosaurus; the tiny, ant-eating Albertonykus; the bird-beaked oviraptorosaurs like Citipati; and birds. Within the past decade, especially, new discoveries have radically changed [...]... Read more »

Under the mistletoe, coevolution is about s and m

by Jeremy Yoder in Denim and Tweed

Plants and plant products, from sprigs of holly to pine boughs, have been traditional winter holiday decorations since before Christmas became Christmas. Nowadays, if we don't resort to plastic imitations, we deck our halls with garlands from a nursery and a tree from a farm. But seasonal decorations have natural histories apart from mantelpieces and door frames—ecological roles and, yes, coevolutionary interactions with other species.

Paralysis deniers have subconscious insight into their disability

by BPS Research Digest in BPS Research Digest

Anosognosia is an intriguing neuropsychological syndrome in which a patient with one or more paralysed limbs denies they have anything wrong with them. In a new investigation, Aikaterini Fotopoulou and her colleagues have shown that some patients fitting this description have a residual, sub-conscious awareness of their disability.

The researchers recruited 14 brain-damaged patients with a completely paralysed left arm, half of whom denied their paralysis (ie they had anosognosia). Next, a........ Read more »

Low-Carbohydrate Diets are Not Created Equal

by Shaheen Lakhan in Brain Blogger

Low-carbohydrate diets have been among the most popular weight-loss strategies of the last several decades. But, new research published in the Annals of Internal Medicine indicates that the type of low-carbohydrate plan one chooses affects not only the waistline, but the risk of mortality. In a large, prospective, observational study, researchers evaluated whether the type [...]... Read more »

Excitable motility

by Becky in It Takes 30

We’ve talked before about the puzzle of how cells like neutrophils figure out how to follow a shallow gradient of attractive chemicals.  In a recent paper (Xiong et al, 2010.  Cells navigate with a local-excitation, global-inhibition excitable network.  PNAS, PMID 20864631) the Devreotes and Iglesias labs describe a new model of how chemotaxis might work.  [...]...
