Starch is that stuff that stiffens your shirts. It's also what most people eat for fuel. Wheat, rice, corn, oats, potatoes are all very starchy foods. Many popular diet plans call starch a second-rate food that should be avoided at all costs. No-starch and low starch diets are favored by irritable bowel communities, while former Weight Watchers, Jenny Craig and Atkins enthusiasts love the new Carb Lovers Diet praising starch. Yet, there may be something good about starch even for those with........ Read more »

Several cases of botulism in Alaskan Natives have occurred as a result of changing Alaskan Native methods of fermenting meat. Traditional food preparation and storage techniques of burying meat underground to ferment have since been modified by the introduction of Western conveniences; Tupperware containers and sealable plastic bags are now being used to create a meaty, anaerobic environment that C. botulinum is happy to vacation in. ...

Do you feel like your grandfather adds more salt to his soup each time you see him? Turns out this is actually one of the physiological effects of aging. In fact, Stevens et al.  reported that the elder required twice as much salt as the young before detecting it in their tomato soup.... Read more »

In part I and part II, we discussed several of the gender gaps in Wikipedia. In this part, we'll talk about reverted edits, blocking, and their association with female and male editors. .
Blocking The hypothesis here was that "Female editors are less likely to be blocked." However, there wasn't a statistically significant difference in the percentage of females blocked (4.39%) and males blocked (4.52%). Surprisingly, females were significantly more likely to be blocked indefinitely (3.85% and 3........ Read more »

One of the main background themes in my history of life series was that extinctions will always happen – they’re a natural part of the biosphere’s evolution. But I never really explained what a mass extinction is. For example, the case of mayflies, who emerge as sexually mature adults simultaneously and live between a few [...]... Read more »
Now that I’m back from visiting amusement parks in Orlando, FL, I think it’s as good a time as any to reveal a little secret of mine: I don’t wear sunscreen. (“Not even in Florida?!”) Not even in Florida. In August.
I want to be really emphatic in saying that I am NOT advocating for people to go without sunscreen. You have to do what works for you. I was raised in sunny places and I almost never get sunburns, and now that I live in New England I’m much more........ Read more »

A few days ago (the day before my 30th birthday actually), my most recent paper, along with Vasili Hauryliuk and Tanel Tenson, "The RelA/SpoT Homolog (RSH) Superfamily: Distribution and Functional Evolution of ppGpp Synthetases and Hydrolases across the Tree of Life" was published with PloS ONE. Hurrah!The RSH proteins comprise a superfamily of enzymes that synthesize and/or hydrolyze the alarmone ppGpp. ppGpp is a nucleotide that acts as an alarm signal, activating the “stringent” response........

The advent of neuroimaging techniques such as magnetic resonance imaging (MRI) has revolutionized autism research. We can now look into the brain and see the "neural correlates" of autism. But, as with any form of correlation, identifying a neural correlate doesn't necessarily mean that we have identified a neural cause.
A case in point. Earlier this week I stumbled across a press release doing the rounds of the internet, proclaiming that "Brain imaging research reveals why autistic indiv........ Read more »

One of the interesting things about the Madl, Baars, Franklin LIDA model is the number of memory stores that it envisages. I have thought of consciousness as the ‘leading edge of memory’, at least of episodic memory. Hence my interest in the model’s use of memory.

No matter that this study proposes that people of the north have bigger brains than those at the equator merely to cope with lower levels of sunlight - it would still cause an uproar if the rather large group of people (including scientists) who regularly commit the moralistic fallacy should ever hear about it.We demonstrate a significant positive relationship between absolute latitude and human orbital volume, an index of eyeball size.

The opening sentence of F. Robin O’Keefe and Luis Chiappe’s new paper in Science this week is a simple statement of fact that threw me for a loop. “Viviparity, or birthing live young,” the paleontologists write, “is common among reptiles, having evolved over 80 times among extant clades.” Think about that for a moment.

Every once in a while I present some tools in the writer’s arsenal for taking over the world. We've talked about writers as brain manipulators, and storytelling as Vulcan mind meld. Today, I will show you how Stephanie Meyer and JK Rowling are actually Borg queens, assimilating all unsuspecting readers in their path.
