11:18 PM | Serious Restrictive Eating Disorders Occur at Any Weight
Although the words “anorexia nervosa” typically conjure up images of emaciated bodies, eating disorders characterized by dietary restriction or weight loss can — and do — occur at any weight. However, precisely because anorexia nervosa is associated with underweight, doctors are less likely to identify eating disorders among individuals who are in the so-called “normal” or above normal weight range, even if they […]

12:00 PM | Does Life Come In XXXS?
Biology concepts – characteristics of life, archaea, bacteria, mycoplasma, synthetic biology, symbiosis, parasitism, nanobacteria, genomeAs part of this blog, we have talked about some pretty small life. Wolffia globosa is the smallest flowering plant, only 0.6 mm long. We also talked about archaea, a different kingdom than bacteria, but still on the smallish side of life. The tardigrade is the toughest animal, but is also one of the smallest, at 100 µm (0.00394 inch).The organism […]

9:00 AM | Environmental risk factors - can we ever know when we're done?
Complexity, confounding, heterogeneity: these are just a few of the issues that can and do play havoc with biomedical research where we attempt to infer causation from observational data. A paper just published in Cancer Research ("Circadian and Melatonin Disruption by Exposure to Light at Night Drives Intrinsic Resistance to Tamoxifen Therapy in Breast Cancer," Dauchy et al.) is a good example of some of the issues.  Reported all over the web, including here by the BBC, the […]

Last week, I ran across this very entertaining piece over in Healthcare Dive about the new ICD-10 codes. The International Classification of Diseases (ICD) is an incredibly useful tool in public health that basically can reduce an injury to a series of numbers. As you can imagine, this is very powerful when it comes to […]

Drinking alcohol during pregnancy is generally considered as not a very good idea. For one, it can cause fetal alcohol syndrome if you are serious about your drinking (reference). It has been associated with smaller babies. And smaller babies is not good (for the babies themselves, presumably for their mothers it is a benefit during […]

Biology concepts – thermosensing, repellent, odor receptors, gustatory receptors, semiochemcialsScience explains our world, and then technology and engineering build a model of that for our use. The better we know how our universe works, the better we can make use of it. In the 1985 film Real Genius, this difference is stated when the scientist students ask what a 6 megawatt laser might be for, one student says, “Let the engineers figure out a use for it.” In this case, they […]

9:00 AM | Have we reached peak longevity?
The July 4 episode of the excellent BBC Radio 4 program, More or Less, addressed a question that demographers and public health researchers have been pondering in recent years: Will upcoming generations be the first to die at younger ages than their parents?  It has been accepted wisdom for a long time that each generation is healthier than the previous one, and life expectancies have risen for generations.  This was largely the result of declining infant and childhood mortality […]

12:00 PM | How Do Mosquitoes Find You?
Biology concepts – semiochemicals, hematophagy, proboscis, thermosensing, TRPA1Sure, mosquitoes suck blood and pass along malaria that kill more humans than any other infectious disease. But would it be good to get rid of them. They provide food for birds – one scientist suggests that elimination of Arctic mosquitoes could reduce northern bird populations by 50%. And mosquitoes pollinate flowers too, like blueberries and cranberries. See, they’re not all bad.We can start our […]
