Multivitamins & Breast Cancer - Is It Too Little Rather Than Too Much?

by Michael Ash in Nutri-Link Ltd - Clinical Education

Multivitamins have recently been flagged in a March 2010 American Journal of Clinical Nutrition article to raise the risk of developing breast cancer amongst a group of Swedish Women. Naturally this paper sounds both alarming and contradictory and merits deeper investigation. Particularly as it is directly opposed by a paper out just 3 month previously in the Public Health Nutrition Journal when a group of nearly 3,000 women with breast cancer were compared to a similar number of controls in rel........

Article review: Career in Academics

by Michelle Lin in Academic Life In Emergency Medicine

What should I do after finishing residency training? What, there's no more training?!Traditionally, graduates enter one of four traditional areas -- academia, community practice, industry, and the military. With the increased financial and research pressures of academic medicine, a study reviewed why physicians pursue a career in academia.Specifically, the authors conducted a literature search of the term "career academic medicine". Articles published during 1986-2006 were included. From the 480........ Read more »

Facebook and Academic Performance

by Dr Shock in Dr Shock MD PhD

Today children are often described as follows
They live in social networks such as Facebook, MySpace, and Second Life gathering friends; they text more than they talk on the phone; and they Twitter the night away often sleeping with their cell phones vibrating by their sides.
A recent study challenges the believes that children have multitasking skills [...]

Gambling on resource scarcity

by Paul Spraycar in Beyond Climate Change

A new study re-examines a famous bet, made in 1980, over whether natural resource scarcity would be reflected in increasing commodity prices over the ensuing decade. By expanding the time period of interest – to 1900-2008 rather than the 1980s only – the researchers find that commodity prices are in fact going up.Paul Ehrlich, a neo-Malthusian, was allowed to choose a basket of five commodities: chrome, copper, nickel, tin, and tungsten. His speculation was that economic growth would........ Read more »

Outbreaks of H5N1 Bird Virus Infection in Wild Birds in time and space: Temperature matters (with cool video)

by Greg Laden in Greg Laden's Blog

It has long been thought that there are linkages between certain viruses and the weather. The flu season is winter (in whichever hemisphere it happens to be winter in) for reasons having to do with the seasons. One early theory posited that the practices of East Asian farmers, as they tended their animals, caused waterfowl and swine and humans to share space closely enough that nasty new influenzas would emerge and spread around the world. Although that explanation for the annual seasonal fl........ Read more »

Mentor Support: an unsung key predictor of weight loss and weight loss maintenance

by mc in begin to dig (b2d) There's one weight loss study that somehow has been in the public eye since 2003. Each time a version of its data gets published, it gets media attention for showing that LOTS of exercise helps maintain weight loss. Now from my reading of that data, that's actually kind of a misrepresentation of the findings in the paper. There are THREE factors that impact weight loss maintenance: caloric restriction (1200-1500kcals), 270-300mins of (vigorous) exercise a week AND ........ Read more »

Flu shots all around! But is it the best way?

by Colin Schultz in CMBR

Lying in bed, wrapped in a comforter, fists clenched. Your teeth are chattering, your body is sore, your head is pounding. You feel horrible, and yet a loved one is trying to do the most unthinkable thing – they want your blanket.
No, you can’t have it! I’m freezing! you say.
Come on, it’ll make you feel [...]... Read more »

Why religion can lead to racism

by Tom Rees in Epiphenom

Religious people are more racist than average. That fact has been known for decades, and it's rather surprising given that mainstream religions are unanimous in preaching racial tolerance. Just why this should be is not well understood.Does religion really cause racism, or is it that are racists drawn to religion? Three recent studies have shed a little light on that question, with fascinating results.Do subconscious religious prompts increase racism?Can you make someone more racist simply by su........

If I had a crystal ball, and could decide who would do well in self managing their pain, and who would not, what would I do? A holy grail for insurance companies and health economists and yes, clinicians, is to find some precise way to decide who needs the most help with their pain, and [...]... Read more »

If You're Going to Taser a Sheep, at Least Do It Right!

On Friday I read with interest a post written by my dear SciBling DrugMonkey conducted by the folks at TASER International on the effects of the TASER on anesthetized, methamphetamine-intoxicated sheep.

Evolving a code: A molecular fossil’s tale

by Lucas in thoughtomics

Every living cell on earth carries a molecular fossil: the ribosome. In a recent paper published in PNAS, researchers from California open the drawer and dust off this ancient remnant. The structure of the ribosome seems to provide hints about the origin of that universal feature of life: the genetic code.
The genetic code is life’s universal [...]... Read more »

The spillover effect

by CJA Bradshaw in ConservationBytes

The so-called ’spillover effect’ is a long-standing debate in conservation ecology. The idea is relatively simple – put in a marine reserve (or, no-take zone, park, whatever you wish to call it as long as it restricts blanket over-fishing) and the area around the reserve eventually profits from the nearby over-production of fish (and other [...]...
