Sex, Stress, and Neurogenesis

by Scicurious in Neurotic Physiology

Sci couldn’t help but notice all the tweets going around the other day talking about how sex stressed you out but was ultimately good for you. She contemplated saving it for a Friday Weird Science, but it’s not THAT weird (though it is interesting), and anyway Sci has something brewing for teh weird skienz. So [...]... Read more »

Can you train an adult brain?

by Greg Laden in Greg Laden's Blog

It is often said that the human brain develops and improves up to a certain age, then becomes stagnant for a while, then slowly (or not so slowly) deteriorates over time. This is an old conception that developed before we knew that neural connections are being modified constantly, and that it is even the [...]... Read more »

The name defines the thing

by Carl in The motor chauvinist

So, astute readers may notice a name change here - I've decided to go back to my old WordPress blog title (which never had more than five posts over its year-long lifespan, a perfect example of my habit of enthusiastically starting projects and never following through). I used to own the domain motorchauvinist.com but no longer. Oh well. Blogger will do for the moment.Why motor chauvinism? I'd like to disassociate myself from the idea that I am in any way interested a) in cars and b) in denigrat........ Read more »

Dog Walking and Human Physical Activity Levels

by William Yates, M.D. in Brain Posts

Increasing physical activity levels is one of the biggest public health challenges. Various environmental manipulations may provide pathways towards increasing the level of physical activity in children and adults.Several research studies support dog ownership as a correlate of increased physical activity levels. Coleman and colleagues examined the role of physical activity and weight status in households with and without dogs. Using the Neighborhood Quality of Life Survey, 32 neighborhoods in........

Cell-Free Artificial Photosynthesis with Frog Foam

by Michele in Promega Connections

We owe a lot to frogs and toads. They help us welcome in spring and summer with their peeps, croaks and snores in the evenings. They serve as bioindicator species that alert us to damaged or toxic environments. And, now, they may even help us kick the fossil fuel habit. Biofuels, based on harvesting and [...]... Read more »

Snake eyes

by Zen Faulkes in NeuroDojo

To many, “snake eyes” is a bad bet at the craps table. To some, it’s a GI Joe character. To a very small, select group, it’s a minor addition to the oeuvre of Brian De Palma. *

Today, I want to look at the most literal meaning of the term imaginable. But, since this is a biology blog, you could probably guess that I was going to end up talking about the eyes of snakes.

I’m willing to bet that when most people visualize snake eyes, they think of something with a vertical slit for ........ Read more »

Ep 132: Science of Superheroes - The Hulk

by westius in Mr Science Show

The science of superheroes is taking a green and nasty turn this week as we discuss the largest superhero of them all, The Hulk. Join myself and our regular superhero expert Dr Boob as we delve into the science of how we might realise The Hulk in the lab. It was one of the more entertaining interviews I have done for the podcast.

Listen in to this show here (or press play below), and read further for more info:

Accepting what life throws at ya

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I was looking to write about a new treatment, or something that is innovative, and you know, there isn’t a whole lot new out there in pain management land. If it wasn’t for Lorimer Moseley’s work on motor imagery and Lance McCracken’s work on acceptance, I think we’d be doing pretty much what I was … Read more... Read more »

The geometry of evolution

by Becky in It Takes 30

Biologists already know lots of reasons to encourage mathematicians to get hooked on biology.  There’s structural biology; population genetics; epidemiology; ecology; bioinformatics; computational neuroscience; and yes, systems biology, to name but a few.  But here is a new one.  How long have we been studying Darwin’s finches?  About 170 years.  In all that time, nobody [...]...

A rose may be a rose but perhaps a calorie's not a calorie

File this one under cool data!Simple study published in Food and Nutrition Research to look at the differences between whole foods and processed foods and the calories the body utilizes to metabolize them (something called diet induced thermogenesis and also known as the thermic effect of food).18 subjects were enrolled in a cross-over study (meaning they each ate both test meals) whereby the thermic effect of food was measured following the ingestion of two different cheese sandwiches.One chees........

Release the fossil pronghorns!! (pronghorns part II)

by Darren Naish in Tetrapod Zoology





I said in the previous pronghorn article that the modern pronghorn - Antilocapra americana - is but the tip of the phylogenetic iceberg, if you will; the only surviving member of a group that was previously far more diverse [the adjacent photo (from wikipedia) shows Ramoceros osborni. Yes, it really looked like that, read on].

As we'll see here, fossil pronghorns encompassed a reasonable amount of diversity: there were kinds with deer-like pseudo-antlers as well as others that superficially........ Read more »

We're happier when busy but our instinct is for idleness

by BPS Research Digest in BPS Research Digest

Forced to wait for fifteen minutes at the airport luggage carousel leaves many of us miserable and irritated. Yet if we'd spent the same waiting time walking to the carousel we'd be far happier. That's according to Christopher Hsee and colleagues, who say we're happier when busy but that unfortunately our instinct is for idleness. Unless we have a reason for being active we choose to do nothing - an evolutionary vestige that ensures we conserve energy.

Consider Hsee's first study. His team offe........ Read more »

Clever New Scheme

by Neuroskeptic in Neuroskeptic

CNS Response are a California-based company who offer a high-tech new approach to the personalized treatment of depression: "referenced EEG" (rEEG). This is not to be confused with qEEG, which I have written about previously. What is rEEG? It involves taking an EEG recording of resting brain activity and sending it - along with a cheque, naturally - to CNS Response, who compare it to their database of over 1,800 psychiatric patients who likewise had EEGs taken before they started on various dru........

Refugee children left behind as eagle lands on the moon

The Wednesday Post - High School Biology FAIL

by James Byrne in Disease Prone

I found a story kicking around the blogosphere this week that’s really got me irritated. According to a new study a bunch of American HIGH SCHOOL BIOLOGY TEACHERS were surveyed and asked to indicate their personal beliefs regarding evolution and the origin of human beings. The results of the survey were then presented in a fancy graphic by another group (go check it out, its depressing but shiny), the only purpose of which seems to be to deaden the impact of the astounding results....

Beating the creationists at their own game?

by hilaryml in Chicken or Egg blog

The presence of “gaps” in the fossil record is one of the main arguments creationists use against evolution. The transition from Coelurosaurian dinosaurs to birds is one such purported gap that creationists like to harp on about.  Evolutionary biologists would argue that Archeopteryx fills this gap quite nicely, but this is disputed by creationists, who argue [...]...

Ivy vs UV, could plant nanoparticles be the new sunscreen?

The trend towards organics has influenced industries like food, coffee and shampoo as well as pretty much everything you can conceivably imagine. Over the past few [...]... Read more »
