Colder May Not Be Cool for Recovery
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
After exercise, cold water immersion at 15°C may offer some improvements in recovery based on performance of a jump task and possibly markers of muscle damage. A colder temperature may not be as effective as cool water, so controlling the treatment parameters based on evidence is important.... Read more »

Online Insomnia Therapy Effective in Clinical Trial
by William Yates, M.D. in Brain Posts
Insomnia of sufficient severity to meet clinical significance is estimated to affect up to 20% of the general population.This makes insomnia an important public health challenge.Effective, inexpensive and accessible programs to treat insomnia are needed.One recent controlled clinical trial supports the promise of an online intervention that incorporates key elements of cognitive behavioral therapy (CBT).Lee Ritterband and colleagues at the University of Virginia recently published a controlled c........

Exercise After Study Boosts Memory
by William Yates, M.D. in Brain Posts
There is significant interest in activities that may boost academic achievement in the classroom.I previously posted on evidence that exercise prior to a learning task improved reading comprehension scores.You can access that post by clicking HERE.Now a study has compared two types of activities after a memorization task in male students.In this study, 60 male students completed a learning task and then were randomized into one of three activities for one hour. The three activities were playing ........ Read more »

Brawn, Brain and Beauty
by Aurametrix team in Aurametrix Blog
In the future all humans will be tall and beautiful look-alikes, as in GATTACA. Or they will split into frail beauties and sturdy beasts, as described in H. G. Wells' The Time Machine. British evolutionary psychologist Oliver Curry and paleoanthropologist Matthew Skinner believe in the possibility of similar scenarios, based on either the rich and poor divide ("gracile" vs "robust" species) or climate change-related evolution (pale hairy giants vs aquatic and space humans). The change may b........ Read more »

Sorry, I Don't Drink
by Mark Lasbury in As Many Exceptions As Rules
Koalas don’t drink a lot of water, but the spinifex hopping mouse and kangaroo rat put him to shame. They never drink. What water they need they get from the seeds they eat and from the fact that they conserve water amazingly well – including the water that they produce during metabolism. Adult mayflies don’t drink either – they don’t have working mouthparts! Of course, some only live a few minutes as adults, so it may not be that big a deal.... Read more »

The Internet asks me about smelly things
by Rosin Cerate in Rosin Cerate
Whenever I'm working on a new post, I like to take a bit of time to check in on the stats for this blog. I'm particularly interested in what people are typing into their search engines to find their way here. For whatever reason, a post I wrote about what poisons smell like is very popular among users of the Internet. I'm taking this as a sign that people like to read about smells, so I thought I'd look into a couple of odour-related search queries via which people have found this blog.'type of ........

Give Thanks For The Cranberry
by Mark Lasbury in As Many Exceptions As Rules
Here comes Thanksgiving! The cranberry is an amazing fruit on its own for several reasons. Its cultivation and botany are unusual, as is its seed dispersal mechanism and structure. However, a major push has been on to understand the medicinal uses of the cranberry. Much debate is taking place as to the usefulness of cranberry compounds, anthocyanidins and polyphenols, in the prevention of urinary tract infections. Cranberry is even having some success in type II diabetes and as an anti-viral age........ Read more »

Mostly Dead Is Slightly Alive
by Mark Lasbury in As Many Exceptions As Rules
Halloween brings stories of the undead, the dead coming back to life, and the dead staying dead but still coming to visit you. But the scariest of all is the prospect of being buried alive. It happened all to often in the most recent three centuries, so people devised some amazing precautions to prevent premature burial. Nowadays it’s less likely to happen, but there are several conditions that can mimic death and could lead to fingernail scratches inside the lid of a casket.... Read more »

Twin Sons Of Different Mothers…… Or Fathers
by Mark Lasbury in As Many Exceptions As Rules
Can a pregnant woman get pregnant? Sounds like a riddle, but really it is superfetation. Getting pregnant in two successive cycles and having twins with different fathers really creates a problem in defining what twins actually are. Twins don’t have to be conceived at the same time, born at the same time, have the same father, or even be of the same “race.”... Read more »

Twins of Different Seasons
by Mark Lasbury in As Many Exceptions As Rules
Twins are born near the same time, that’s one of the things that makes them twins. But do they have to be born close to one another? The record is twins born 104 days apart. The key is to get the twins past 25 weeks so the lungs will be mature enough, but if one twin is delivered, the second might be subjected to delayed interval delivery to give the lungs longer to grow....

You And Mom Are Never Apart
