Migraine is a recurring headache of moderate to severe intensity that is associated with gastrointestinal, neurologic, and autonomic symptoms. As the most common of the chronic headache disorders, migraine affects 18% of women and 6% of men in the United States. More than one-half of all migraine sufferers report significant disability with the migraine. While [...]... Read more »

There are lots of online health tests available, some I’ve reviewed on Sciencebase over the years, such as those that help you answer the question are you at risk of diabetes.

What do you do when you’re trying to get somewhere, and you get conflicting information? The person in the passenger’s seat swears he knows which way to turn, but the GPS unit in your car tells you to go the opposite direction. Problematic. Indeed, possibly relationship-changing depending on who’s in the passenger seat.
Still, humans generally have it easy when it comes to navigating. Our decisions are usually “turn left” or “turn right.” We are close........ Read more »

New technology has that unique property of creating fascinating moral debates, which is especially so when it relates to new technology regarding life, death, or in this case: fertility. For a few years, technology has been available for the cryo-preservation of oocytes or ovarian tissue, which is used to help save the fertility of women who run the risk of losing it, for instance due to chemotherapy. Now, the question is raised whether such techniques should be made available to healthy women a........ Read more »

Mark Regnerus, a sociologist at the University of Texas, has been looking into how family harmony is affected when children adopt religious beliefs different from their parents'. You might know the name already - he's wrote a book a couple of years back: Forbidden Fruit: Sex and Religion in the Lives of American Teenagers.In his latest paper, he (along with grad student Charles Stokes) has analysed data from the US National Longitudinal Study of Adolescent Health. What he was looking at was diff........ Read more »

Photo and video taken last week… the food capturing mode of Crotalus adamanteus can easily be described as “predatory,” their relative contribution, or “predatory influence,” within ecosystems is not especially clear. Typically, when viewing a system’s predator-prey functionality the response and feedback between prey availability (how many are present) is weighed against the number of predators acting antagonistically within the system…...

"Jealousy can no more bear to lose sight of [its] objects than love" George Eliot (1860)The mind is altered by fear that our beloved is about to be lured away. Attention and memory systems are hijacked, turned to focus on attractive rivals. That's according to Jon Maner and colleagues who say theirs is one of the first studies to look at how romantic jealousy alters low-level cognitive functioning.Maner's team conducted four studies with hundreds of heterosexual student participants.

Who's more likely to start digging prematurely: one guy with a metal-detector looking for an old nail, or a field full of people with metal-detectors searching for buried treasure? In any area of science, there will be some things which are more popular than others - maybe a certain gene, a protein, or a part of the brain. It's only natural and proper that some things get of lot of attention if they seem to be scientifically important. But Thomas Pfeiffer and Robert Hoffmann warn in a PLoS One p........ Read more »

A major public policy concern is the well known fact that many minority students under-achieve scholastically. The roots of the discrepancy in performance of some minorities and their white counterparts has been attributed to many causes, such as socioeconomic disparities and poor school systems in minority communities. Many of the explanations, however, focus on the [...]... Read more »

Relative to its body size, the toco toucan dons the largest bill of any bird. This magnificent hood ornament serves the toucan well. It functions as a refined feeding tool that enables the toucan to skin fruit and snare prey. It can be wielded as a warning flag to discourage rivals and ward off predators. And, as Charles Darwin noted, the enormity of the toucan's beak may serve as a bright beacon of virility to potential mates.... Read more »

The freshwater pearl mussel (Margaritifera margaritifera) is a very long-lived beast, though as for many of these species its life span is poorly studied. There are too many bivalves and not enough researchers - remember that we live in a world in which we can't even determine lobster ages with any degree of certainty. Like many bivalves, lobster biochemistry doesn't seem to change with age in any usefully measurable way. You might recall research into the longevity of another bivalve, the arcti........ Read more »

News today has spread about new stem cell research out of China. Two teams used mouse fibroblasts, a kind of cell found in skin connective tissues, to create induced pluripotent skin cells (iPS), which were then used to create living mice.Their breakthrough research suggests that both cloning full animals from stem cells and the creation of completely pluripotent stem cells from skin cells are both not only possible, but a current reality. The two teams published separately, in Nature and Cell -........ Read more »

One of the most famous findings in animal behaviour is that the dance of honeybees in the hive is correlated with the location of their food.

What makes us honest? The process of natural selection that honed our minds is supposedly one of cutthroat competition. We’re quite obviously driven to succeed, but often we choose not to lie or steal or cheat even when we rationally expect no consequences. In the Freudian account, it’s the rational superego that restrains the selfish [...]... Read more »
