Sex after dawn: Marriage and natural selection

by Jeremy Yoder in Denim and Tweed

The book Sex at Dawn, by Christopher Ryan and Cacilda Jethá, has had a lot of press in the last month—it first popped up on my radar with Eric Michael Johnson's review for SEED, and then it became unavoidable (for me, anyway) when Dan Savage devoted a whole column and podcast to it. The thesis of Sex at Dawn is that early humans were highly promiscuous, and that modern expectations of monogamy are probably not consistent with our biology. I haven't read the book yet, but the discussion surrou........ Read more »

It's never too late to memorise a 60,000 word poem

by BPS Research Digest in BPS Research Digest

Pounding the treadmill in 1993, John Basinger, aged 58, decided to complement his physical exercise by memorising the 12 books, 10,565 lines and 60,000 words that comprise the Second Edition of John Milton's epic poem Paradise Lost. Nine years later he achieved his goal, performing the poem from memory over a three-day period, and since then he has recited the poem publicly on numerous occasions. When the psychologist John Seamon of Wesleyan University witnessed one of those performances in Dece........ Read more »

Article Review: Facebook, Professionalism, and Physicians

by Michelle Lin in Academic Life In Emergency Medicine

Facebook is worldwide. The medical educator's dilemma about Facebook and professionalism seems universal. How do we teach medical students the importance of the digital footprints on publicly viewable websites? A landmark article, published by Dr. Chretein in JAMA in 2009, surveyed U.S. medical school deans on unprofessional behavior on Facebook. She found that 60% of medical schools documented incidences of unprofessional online postings.In contrast, Medical Education just published a cross-sec........ Read more »

Not everything's caused by obesity: Brain and memory function edition

by Yoni Freedhoff in Weighty Matters

Good lord.I know people like to blame obesity for everything. Every disease, every problem - everything.You know what I'm blaming on it today? Authors' and peer reviewers' attitudes about their studies and results.Last Tuesday I was asked by CTV to read a study that was pending publication in the Journal of the American Geriatrics Society so that I could comment on it for the national news. The study looked at 8,745 women between the ages of 65-79 free of dementia and evaluated their weight a........ Read more »

English-Only at Bon Secours

Surgical Residents more health complaints than other employees

by Dr Shock in Dr Shock MD PhD

In a recent study in The Netherlands the researchers found that surgical residents experienced more health complaints than the average member of the Dutch working population (4.0 versus 2.5; p = 0.000). Residents in training (n= 400) were sent self report questionnaires of which 254 of 400 (64%) residents returned questionnaires that were eligible for [...]

Scientific Ethics and the Myth of Stalin's Ape-Man Superwarriors

by Eric Michael Johnson in The Primate Diaries in Exile

Why the Soviets would fund a human-chimp hybridization program in the first place and what can be learned from this sordid tale of ethical misconduct is an important topic and fascinating in its own right. Ivanov represents a scientist, widely respected in his field, whose dedication to find out if something could be done blinded him to ask whether it should be done. It also reminds us of the role that politics can play in the development of scientific research even if the scientists directly in........ Read more »

Elasmobranch “Outbreak” Caused by Migration?

mining physics for “grounbreaking” papers

by Greg Fish in weird things

Black holes are immensely fascinating cosmic phenomena. They’re not even objects but places where much of what we know about physics is put on its head, twisted forward, backwards, sideways, blended together in nearly infinite quantum states, spat out, and then sucked back into violent maelstroms of pure self-gravitating energy in a display of the [...]...

Intuition and other failings in clinical reasoning

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Einstein is accredited with saying “The important thing is not to stop questioning” while Euripedes apparently said “Question everything. Learn something. Answer nothing.” I’m sure of the origins of neither quote – but I think I must have inhaled both of them when I was a toddler because I have never stopped asking ‘why’! In … Read more... Read more »

ADHD and creativity

by sandygautam in The Mouse Trap

Image via Wikipedia ADHD has traditionally been conceptualized in terms of deficits- that of attention , impulse control or motor restraint; but the new neurodiversity paradigm forces us to take a more balanced look and acknowledge the strengths that the ADHD kid may have- divergent thinking, spontaneity and high energy and vitality.

Cherry Picking to Generalize ~ retrospective meta-power analysis using Cohen’s f^2 of NASA temp visualization

Previously, I plotted a grid of NASA GISS global temps in ggplot2 to show general trends by the brute force method.

Quasars in the very early universe

by Charles Daney in Science and Reason

Quasars are powered by the gravitational (potential) energy of their central supermassive black holes. However, their distinctive features – their extremely high luminosity in particular – are very dependent on characteristics of matter close to the black hole. Most supermassive black holes (SMBH), including those at the centers of the Milky Way and our close neighbor M31 (Andromeda), are responsible for fairly small amounts of radiation in any part of the electromagnetic spectrum.

Collaboration 2.0

Information technology is letting people around the world come together in unprecedented ways.

How are British kids doing these days?

by Tom Rees in Epiphenom

British society, like that of most industrialized nations, has gone through enormous changes in recent decades. But it's hard to get objective data on what the impact has been on the people living there.

Which is why I was interested to see a recent study by Stephen Collishaw, of Cardiff University, and colleagues. They compared data from two studies, one in 1986 and one in 2006, that asked adolescents (aged 16-17) about their state of mind. Whether they felt anxious, depressed, worried, irrita........

How viruses hijack cellular transport systems

by Lab Rat in Lab Rat

Even in the world of the very small, there are significant differences in size. A eukaryote cell (i.e a human cell) for example is relatively big, in microscopic terms. Most other things that interact with the cell at the microscopic level, are far smaller than it, such as bateria, viruses and signalling molecules.A virus isn't much more than a small capsule of proteins with a little bit of DNA inside. Once it gets inside a eukaryote cell, it's very much in the position of a small child wanderin........ Read more »

Across disciplines, what motivates or prevents faculty staff archiving?

by Christina Pikas in Christina's LIS Rant

This article is in early view at JASIST. It looks like it comes from the author's dissertation. It isn't terribly earth-shattering, but it's well done, it provides more evidence, and there are definitely some implications for library/IR manager practice. Here's the citation: Kim, J. (2010).
