Reconsidering the Origins of Marine Life and All Life

by Dr. M in Deep Sea News

What is the origin story of deep-sea organisms? For decades, we thought shallow coastal waters were the cradle of marine life repeatedly pumping species into the deep.  This is the simplest story.  The more complex origin story involves multiple anoxic events, catastrophic events, survival of the fittest, so on and so forth with species originating [...]...

Carving Personalities From The Womb

by Akshat Rathi in Contemplation

How Much Is Decided Even Before Birth?
“The daughter of Virata… (was) exceedingly afflicted by grief on account of the death of her husband…they all feared that the embryo in her womb might be destroyed.” – The Mahabharata (~500 BC).

This quote from the Mahabharata, and many other examples from literature, reiterate the sentiment that the emotional [...]... Read more »

Religion makes you a fat non-smoker

by Tom Rees in Epiphenom

You might have seen news reports about a recent study showing that religious people are no healthier than non-religious. The cynical among you might be wondering what on Earth's going on here, given that other studies have shown the opposite! A classic example of scientists proving whatever they want to, perhaps?Well, no. There's a good reason that this study has found something different, and that's because it's not asking quite the same question.You see, working out the relationship between re........ Read more »

Viva la Neo-Fisherian Liberation Front!

by jebyrnes in I'm a chordata, urochordata!

Significant p-values. For so many scientists using statistics, this is your lord. Your master. Heck, it has its own facebook group filed under religious affiliations (ok, so, maybe I created that.) And it is a concept to whose slavish devotion we may have sacrificed a good bit of forward progress [...]... Read more »

XMRV not found in 170 additional UK chronic fatigue syndrome patients

by Vincent Racaniello in virology blog

A new retrovirus, xenotropic murine leukaemia virus-related virus (XMRV), first identified in tumor tissue of individuals with prostate cancer, was subsequently found in 68 of 101 US patients with chronic fatigue syndrome (CFS). XMRV was not detected in blood samples of 186 confirmed CFS patients in the United Kingdom. A second independent study in the [...]... Read more »

Better Sleep, Better Learning?

by Rob Mitchum in ScienceLife

Imagine a child who gets good grades in school, listens well to his teacher, and is commended for his good behavior in the classroom. Then slowly, his grades start to decline, he grows moodier, and his teacher reports that his attention often drifts in class. The parents are stumped - they can’t think of anything [...]...

Here’s looking at us

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

For most of my clinical working life the focus in pain management has been on factors that identify people who have a high risk of developing long-term disability associated with their pain. The tide is turning, though, and increasingly we’re seeing papers published that look instead at treatment provider attitudes, beliefs and behaviours as [...]... Read more »

What’s in a name? Genetic overlap between major psychiatric disorders

by Kevin Mitchell in Wiring the Brain

The criteria used to assign patients to specific psychiatric disease categories are set out in the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association.  (There is also a World Health Organisation equivalent, the International Classification of Disease).  Every so often, these criteria are revised to reflect new research and changing concepts of disease.  The APA has just released a draft of preliminary revisions to the current diagnost........

Five Questions About Lysogeny

by Merry Youle in Small Things Considered

Lysogeny—a nasty time bomb or a mutually beneficial symbiosis? A prophage gone lytic will murder its host, but a symbiotic picture can well be argued. Here are some thoughts about the ongoing give-and-take. More details are still emerging. 1. If you are a phage, why be temperate? A phage at the crossroads. Lambda (λ), the intensely- studied temperate...... Read more »

Broken teeth tell of tough times for Smilodon

by Laelaps in Laelaps

A reconstruction of Smilodon, photographed at the American Museum of Natural History.

When it comes to animals, encyclopedias often present us with generalized descriptions. Where a creature lives, what color it is, what it eats, and other tidbits of information are listed to distinguish one species from another, but what is lost is an appreciation of variation. Be they genetic, anatomical, or behavioral, variations are grist for natural selection's mill, and if you study any species in de........ Read more »

Autism and Asperger’s in the DSM-V: Thoughts on clinical utility

by Nestor Lopez-Duran PhD in Child-Psych

Last week after writing about the DSM-V “Temper Dysregulation Disorder with Dysphoria,” I received several emails asking my opinion regarding the proposed merger of autism and Asperger’s disorder into a single ’spectrum’ category.  This change has clearly generated some significant political debate in the media and the blogosphere, with some in favor of the change [...]...

Speaking truth to Slow Food

by Jeremy in Agricultural Biodiversity Weblog

Slow Food is against standardization, right? Slow Food is for diversity, right? Well, sort of. That is certainly the rhetoric, but a paper by Ariane Lotti in Agriculture and Human Values suggests that the practice can be rather different.
Lotti, who’s something of an insider, analyzes one of Slow Food’s projects in detail and comes to [...]... Read more »

Repression debunked

by BPS Research Digest in BPS Research Digest

Psychologists in Denmark may have hammered the final nail into the coffin containing 'repression' - the idea, made popular by psychoanalysis, that negative, emotional memories are particularly prone to be being locked up out of conscious reach.Simon Nørby and his colleagues at the University of Copenhagen presented dozens of undergrad participants with word pairs, each made up of a cue word and an unrelated target word. Past research has suggested that people are able to deliberately forget som........ Read more »

Leaf-Cutter Ants Dabble with Nitrogen Fixation

by Laura Klappenbach in About Animals / Wildlife

Leaf-cutter ants are crafty cultivators. They tend vast gardens of fungus that they harvest to feed their minions. In return, the ants care for the fungus. They constantly clip and compost bits of leaves to form a rich substrate on which the fungus thrives. When the fungus is attacked by pathogens, the ants fight back, armed with bacteria that counteract the pathogen.... Read more »

Women Online Shopping: Shop Until You Drop?

by Dr Shock in Dr Shock MD PhD

Personally I like online shopping mainly because it’s easy, fast and convenient, you can shop when you want to anywhere you want to. There’s a gender gap in online shopping. More men than women engage in online shopping and make online purchases while in the offline world women love to shop.
Until recent very few [...]
