Walking and cycling to work prevents obesity?

by Yoni Freedhoff in Weighty Matters

Hmmm.I'll admit up front that I can't access the full text of the article Walking and Cycling to Health: A Comparative Analysis of City, State, and International Data, so I can't comment on methodology.The study was large in that it looked at 14 countries, all 50 US states and 50 of the largest US cities for a relationship between active transportation (walking and cycling to work) and obesity.The abstract (and the media) strongly suggest that walking and cycling to work helps to prevent obesity........

Overlooking the familiar in cataloging biodiversity

by Madhusudan Katti in a leafwarbler's gleanings

Familiarity, they say, breeds contempt. Or, even if we aren't actually contemptuous of the familiar, we often simply ignore it. It is not surprising, then—although it should be—that Tapinoma sessile, the odorous house ant of North America, the very same little brown one that is pictured above, and that you may well have swept off your kitchen counter today, remains relatively poorly studied! It is so widespread and common across a variety of habitats in ........ Read more »

Who drops out of CBT for chronic pain?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Wouldn’t it be wonderful if everyone we saw was ready for self management and committed to putting everything in place? Wouldn’t it be even better if we could tell who was and who wasn’t going to drop out? Then we could focus treatment on people who were ready for treatment, and help those who are … Read more...

Flynn effect for memory could invalidate neuropsychologists' tests

by BPS Research Digest in BPS Research Digest

In Western countries, scores on IQ tests have been rising for several decades - the Flynn effect, named after the political scientist James Flynn. Now Sallie Baxendale at the Institute of Neurology has provided evidence that a similar effect has occurred for the standardised memory tests that are used by clinical neuropsychologists, a finding with implications for the diagnosis of memory problems in contemporary patients.

Baxendale focused on the Adult Memory and Information Processing Battery ........ Read more »

Measuring the Bullwhip Effect in Supply Chains

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

The bullwhip effect in supply chains has been around for some time now. The term "bullwhip effect" originated at Procter & Gamble, and is defined as: demand amplification across echelons within a supply chain. This describes the effect that end customer demand may be very static (as for "Pampers" by Procter & Gamble), but the demand experienced by the manufacturer or supplier shows amplified demand variations. (Fransoo and Wouters (2000))

PLoS ONE: Children from Wealthier Families More Likely to Meet Criteria for an ASD

by Lindsay in Autist's Corner

Describes research analyzing 2002-2004 autism prevalence data cross-referenced with socioeconomic data from the 2000 census on the geographic areas under surveillance in the autism-prevalence studies. My post also addresses to what extent these results show a link between autism and SES independent of wealthier families' greater access to health-care services.... Read more »

Addicted to Love

by Shaheen Lakhan in Brain Blogger

Robert Palmer may have already known what researchers now claim: Love can be an addiction. In a new study published in the American Journal of Drug and Alcohol Abuse, investigators examined and compared the clinical, psychological and biological details of love, passion, gambling, and substance dependence. It turns out that an addiction to love is [...]... Read more »

Nanofibre paint that kills MRSA

by Lab Rat in Lab Rat

MRSA, the antibiotic resistant form of Staphylococcus aureus is a major problem in hospitals. The antibiotic resistance makes it hard to erradicate, not just from patients, but in the surounding environment, on surfaces, on medical equipment, on the walls of the hospital. In order to minimise the numbers of dangerous bacteria found in hospital surroundings, quite a lot of research has gone into creating antibacterial coverings or coatings that would reduce the number of bacteria p.

Sinus infections: what we do and don’t know

by PalMD in White Coat Underground

Acute sinusitis—a “sinus infection”—is one of the most common problems seen by primary care physicians.  The current preferred terminology is “acute rhinosinusitis”, a term which is more descriptive of how the disease works (its “etiology”).  In most cases, a patient will first develop cold or allergy symptoms including a runny, congested nose (“rhinitis”).  The swelling [...]...

The problem with drug trials

Should randomised trials be the only type of evidence accepted for rolling out drug treatments?
If so, then two researchers wrote in the Lancet this week that that we face a problem:
The evidence we have might not be the evidence we need, and the evidence that we need may never become available.
They are writing in response [...]... Read more »

Global Temperature Proxy Reconstructions ~ Bayesian extrapolation of warming w/ rjags

by apeescape in mind of a Markov chain

There are a bunch of “hockey sticks” that calculate past global temps. through the use of proxies when instrumental data is absent.

Of blood and breath: metabolite-based diagnosis of ovarian cancer

by Aurametrix team in Olfactics and Diagnostics

Physicians always knew that breath contains clues to diseases. Chemicals in breath often correlate with chemicals in saliva and blood - be it alcohol, anaesthetics or other metabolites (see, for example, this study by Dr Andreas Hengstenberg).As one of my interests is breath-based detection of ovarian cancer, I took note of the recent paper claiming 99% to 100% accuracy of detecting ovarian cancer by metabolites in blood. The authors used customized functional support vector machine-based machin........ Read more »

Unraveling the Ocean Methane Paradox

by Sarah in Curious!

Mention methane production, and cows or oil companies usually come to mind. But much of the methane in the atmosphere (1-4%) actually escapes from the oceans, some of it produced by microbes known as methanogens (like Methanosarcina acetivorans, above). Some methanogens live in anaerobic – oxygen-free – sediments on the seafloor. Others make their homes in anaerobic fish intestines, the guts of some plankton, or fish and plankton fecal matter. Methanogens live in anaerobic environments. ........ Read more »

Putting a number on it: Maned wolf survival rates

How can you conserve a large carnivore when you don’t know how many of them exist?
