Obesity Genes And Weight Loss After Gastric Bypass

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Gastric bypass surgery is often considered the “gold-standard” for bariatric surgery and is now widely recommended for the treatment of severe obesity.
But, as I have often blogged before, no form of bariatric surgery guarantees success and patients are often disappointed with the amount of weight they lose (or that fact that there is some weight [...]... Read more »

Are magicians master mimes?

by Zen Faulkes in NeuroDojo

Research on magic has been getting a lot of attention recently, but most of the focus has been on the psychology of the audience.

But what can we learn by studying the performer?

One of the things you need to be a magician, particularly a close-up magician who works with cards or coins, is dexterity. I tried to learn some basic card tricks once, and failed. It requires some very fine motor control, and I didn’t put in enough work to master it.

Many illusions rely on the magician imitating ........ Read more »

A Scientific Limit to (Male) Sexiness

by Sharon Neufeldt in I Can Has Science?

For most animal species, males must compete with one another to win the attention of a female. This competition can involve active sparring – for example, bighorn sheep will sometimes clash heads over a lady sheep. For other animals, such … Continue reading →... Read more »

Human DNA in bacterial genomes? Yes? No? Maybe?

by Nicholas Loman in Pathogens: Genes and Genomes

Carl Sagan once said that “extraordinary claims require extraordinary evidence”
and that basis I was primed for scepticism when I first glanced at this paper in mBio, which reports apparently human DNA sequences
(specifically from the Line 1 retrotransposon) within
a bacterial genome (that of the obligate human pathogen, Neisseria gonorrhoeae).
But the most exciting scientific reports are those that overturn one’s
assumptions and force one to reali........ Read more »

Female fruitfly fecundity

by Wellcome Trust in Wellcome Trust Blog

The frequency with which mating occurs has differing consequences for males and female fruitflies in terms of their fitness and lifespan. For males, the more mates they have, the better their chances of reproductive success. But for females, a shift to too much mating and reproduction may be costly in terms of lifespan, given the [...]... Read more »

Trick of the Trade: Serial lactate measurements in sepsis?

by Michelle Lin in Academic Life In Emergency Medicine

Does your Emergency Department have computerized spectrophotometric catheters to measure continuous central venous oxygen saturation (ScvO2) in early goal directed therapy (EGDT) for severe sepsis? That's what was used in the original Rivers' EGDT study.I've never even seen one before.Many emergency physicians are getting around not having the specialized equipment issue by obtaining intermittent venous blood gas measurements off of a central venous line.But what if you had a 30 y/o wo........

Mitigation or Contingency Strategies against Disruptions

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Uncertainty can be categorized in continuous risk, more slowly changing patterns, and disruptions, which describe abrupt changes in a system.
Tomlin (2006) investigates the question which supply chain strategies perform best when dealing with the later.

Mitigation vs. Contingency Planning
From case studies analyzed in literature the author first deducts disruption management strategies used in practices. The summary can be seen in figure 1.

Think the gym's gonna make you slim? Think again.

by Yoni Freedhoff in Weighty Matters

Not sure why we're still funding exercise for weight loss studies as two recent comprehensive reviews of the medical literature have concluded that weight loss by means of exclusively exercise interventions run in the order of a 1-3% loss in response to 180 mins/wk of exercise and no loss at all if less than 150 mins/wk, but yet here's another one to discuss.What's a bit different about this study is that it was long - 18 months and hence perhaps will yield a different outcome.So what'd the stud........

Milgram's obedience studies - not about obedience after all?

by BPS Research Digest in BPS Research Digest

Stanley Milgram's seminal experiments in the 1960s may not have been a demonstration of obedience to authority after all, a new study claims.

Milgram appalled the world when he showed the willingness of ordinary people to administer a lethal electric shock to an innocent person, simply because an experimenter ordered them to do so. Participants believed they were punishing an unsuccessful 'learner' in a learning task; the reality was the learner was a stooge. The conventional view is that the ........ Read more »

The power of learning a second language: look to the caudate

by Scicurious in Neurotic Physiology

Sci’s terrible at languages. TERRIBLE. In my time, I’ve successfully mastered English, and attempted to master four other languages (five if you count a brief foray into Elvish when I was 15, but that doesn’t really count) in my time. I have failed at ALL of them. Every once in a while I would achieve [...]... Read more »

Sustainability and the triple bottom line

by Jan Husdal in

Sustainability has become a huge buzzword, both in today's business world and within the broader facets of society. Sustainability has evolved from a perspective and investigation of standalone research in social and environmental areas, through a corporate social responsibility perspective, and towards a convergence of perspectives of sustainability as the triple bottom line.

Revival of the cell phone vs. the brain?

by Casey Rentz in Natural Selections

I don't want to hear it again--cell phone waves are harmful to your brain...stick your face close enough for long enough and you'll turn to mush. But, there's a new paper out there that I'm afraid might catch on as fodder for the pseudoscience susceptible.[Just cool animation. Not part of the study.]Scientists at Caltech recently found that weak electrical fields in the brain might cause neurons to fire in sync. It's really kinda neat. Researchers dropped a cluster of minuscule electrodes into a........ Read more »

Deep sea carbon cycling: microbial action, and mystery

by Kevin Bonham in Food Matters

How excited was I to learn that the most recent issue of Nature Geoscience had a special focus on deep sea carbon cycling? I admit it, pretty excited. I was even more excited to learn that one of the 3 papers making up this special focus was about the microbial component of deep sea carbon cycling. This may not be something that you think about every day, but I do... well most days at least. The first two sentences of this paper explain why I find this topic so interesting.

The Grand Challenge of Aerosolised Vaccines

by Connor Bamford in The Rule of 6ix

Despite the development of effective vaccines, many human populations are currently at the mercy of numerous endemic viral pathogens. Measles virus is one such pathogen that, in 2008, was responsible for 164,000 deaths; the worst effected areas are South-East Asia and Africa (WHO stats can be found here). You might find this surprising as there is currently a very good measles vaccine in use – in fact you probably received at some point during childhood and are protected from future in........
