Fluke or Trend? ‘Calcium Causes Heart Disease’
by Alvin Lin in United Academics
Snap! Ouch! That’s from my head doing a double take. All these years, I thought the calcium vs heart disease thing was a conspiracy arranged by one researcher and publication. However, 3 months ago, I stumbled upon some corroborating studies by other researchers in other journals. Even the US Preventive Services Task Force recently came out against low dose calcium (less than 1,000mg/d) in post-menopausal women because they could not find conclusive evidence of benefit in the face of a ........

Potato Famine Sequenced
by Andrew Porterfield in United Academics
The Irish Famine (or “Great Potato Famine” if you live outside the Emerald Isle) killed one million people and forced another million to leave the country between 1845 and 1852. It was caused by a blight on the country’s main food stock—the Irish “Lumper” potato. Now, researchers have identified the genome of the blight behind the famine.... Read more »

Could you fill a beaker with the fungi in your body?
by Fungi in Bath Fungal Research
--> The mycobiome is starting to get a little traction!When will we know the weight of the fungi on and in our bodies? The human microbiota has been recognized as hugely important in the last few years, but that has almost entirely focused on bacteria. I’ve been interested in the mycobiome of the human built environment for a while, and I certainly haven’t been alone. People tend to think of fungi as a problem in buildings, on or in plants, and in the outside air. However, there is ........ Read more »

Nonessential heat shock proteins affect Candida albicans virulence
by Fungi in Bath Fungal Research
Picking up on my infatuation with all things Hsp, today more on the effects of two of the large Hsps on Candida albicans biofilm formation and virulence in mice and worms.Ssa1, a member of the Hsp70 family, is traditionally implicated in protein folding and entwining. Following heat shock, Ssa1 expression increases, which is a hallmark of heat shock proteins. Recently, Ssa1’s role in Candida albicans’ virulence has been extensively characterized. A series of experiments involving C. al........ Read more »

Microbial Misadventures: Exploits in Botulism & Pruno In Our Prison Population
by Rebecca Kreston in BODY HORRORS
Drinking pruno is a risky endeavor, both in terms of its offense to culinary sensibilities and to one's health. However, turned stomachs are not the only hazard here; you may add a desire to avoid botulism to your list of reasons to shy away from you'r mates latest batch of prison hooch. The soil-dwelling bacterium Clostridium botulinum can contaminate fruits and veggies, and, in warm, oxygen-deprived conditions, produces the neuroparalytic toxin botulinum.

New Reliable Blood Test Can Detect Depression
by Pieter Carriere in United Academics
Depression or Major Depressive Disorder (MDD) has multiple genetic and environmental causes. Genetic factors are hard to find and the discovered factors usually are also associated with other mood disorders. Furthermore, twin studies reveal that genetics can predict 37% of the depressions, which is a much lower heritability than in bipolar disorder, a comparable mood disorder (reviewed in Belmaker et al., 2008). ...

Big data for autism and the promise of newborn bloodspots
by Paul Whiteley in Questioning Answers
An episode of the BBC program Horizon on 'Big Data' recently caught my attention. The content was a fascinating insight into how we are living in a data-rich age and how trawling/mining/dredging such data has the ability to advance medicine, predict crime and even make someone a few quid/dollars/euros on the stock market.Gone (data) fishing @ Wikipedia I'm a big believer in big data.

Marijuana and Diabetes: Does Pot Make You Thin?

Teasing out the insulin effect.
On the face of it, the study seems to come out of left field: A group of researchers claimed that marijuana smokers showed 16 per cent lower fasting insulin levels than non-smokers. The study, called “The Impact of Marijuana Use on Glucose, Insulin, and Insulin Resistance among US Adults,” is in press for The American Journal of Medicine.

Bright Lights, Cold Bodies - The Near-Death Experience Explained

Last February, Dr. Sam Parnia, an intensive care physician who has been researching near-death experiences for the past 15 years, published his new book ‘Erasing death: The Science That is Rewriting the Boundaries Between Life and Death’. Following the release of that book, Dr. Parnia was interviewed on National Public Radio in the US.

tumblr: bellapaige88On average, 9.5/1000 population has epilepsy in Low and Middle Income Countries (LAMIC). A research which has resulted in the global campaign against epilepsy has shown, the gap between treatment need and the treatment provision worldwide is approximately 70% [1].
