how evolution shapes brains and microchips

by Greg Fish in weird things

What do brains and computer chips have in common? Not that much. Sure both use electricity, but in neurons the origin of electrical pulses is chemical while for computer chips it comes from electrical currents. Neurons are highly plastic, rearranging their connections to adapt to new information while computer chips are locked in their arrangement for their entire existence. But one thing they do share is the pattern of connections in their overall structure, [...]... Read more »

Drug deaths and confirmation bias

by Euan in Dr Euan Lawson| Doctor Writer

The median age of death if you are a drug user living in the NW of England in the 21st century is 41.4 years. Just to add a little international colour to that statistic let’s put that in a global context: the life expectancy in Afghanistan is 43.8 years and only one country (out of 195) [...]...

Partula spp. from Society Islands. Photo Credit: Marc Agren
In a short, but sweet, paper by Lee et al. published in the Current Biology, there is a “glimmer of hope” for montane tahitian tree snails (Mollusca, Gastropoda, Partulidae, Partula spp.). They examined the mitochondrial haplotype diversity of tree snail specimens locked away [...]... Read more »

Is Bipolar Disorder a Circadian Rhythm Problem?

by William Yates, M.D. in Brain Posts

By Hannah Dunbar (Brain Post Note: Hannah Dunbar is a Oral Roberts University undergraduate student who is doing a summer research elective with me. She will be providing some guest posts over the next two months related to her interest in sleep and bipolar disorder.) Bipolar disorder is commonly characterized by sleep fluctations and distrubance of a regular circadian rhythm. It is logical to explore the role of circadian clock genes in bipolar disorder genetic studies. Pediatric bipolar dis........ Read more »

Graffiti and Poetry in a Synthetic Genome

The Promise of a Near-Miss

by Rob Mitchum in ScienceLife

A critical step in the design of any clinical trial is picking the right primary endpoint, the result that will usually make or break the study. That’s more difficult than it sounds - one’s hope is to cure a disease or relieve a patient’s symptoms, but choosing the best specific measure for those goals is [...]... Read more »

Autism and white Matter/Myelination: the opposite of creativty/psychosis phenotype?

by sandygautam in The Mouse Trap

A new paper by Ben Bashat et al extends their earlier findings that had found that there was accelerated maturation of white matter in children with Autism. In this new paper they use Tract Based Spatial statistics (TBSS) to determine the white matter integrity of children (age around 3 years) with Autism as More >Rating: 0.0/10 (0 votes cast)

Fish was fossil frog's last meal

by Laelaps in Laelaps

The skeleton of Palaeobatrachus from Lake Enspel, Germany. From Wuttke and Poschmann, 2010.

In On the Origin of Species, Charles Darwin said of the fossil record:

For my part, following out Lyell's metaphor, I look at the natural geological record, as a history of the world imperfectly kept, and written in a changing dialect; of this history we possess the last volume alone, relating only to two or three countries. Of this volume, only here and there a short chapter has been preserved; an........ Read more »

Can Men's Risk-Taking Behaviours be called 'Health Promotion'?

by Ultimo167 in Strong Silent Types

Soffer (2010) thinks that men do 'type 1' health-promoting behaviours (exercise, diet and not snacking) better than women, although he claims that women are better at 'type 2' health-promoting behaviours (not smoking or drinking, sleeping well and eating breakfast) than men. But who gets stressed more?... Read more »

Ballistics experts of the bug world

by Katie Kline in EcoTone

Meet the ballistics experts of the bug world: A quick draw beetle that fires volatile liquids with the pulse of a Tommy Gun, aphids that self-combust at the threat of a predator and a double-pistoled worm that sprays its victim with streams of goo. Of course, these insects are not the only invertebrates carrying chemical artillery—bees are maybe the most famous projectile-launching bugs around. The below insects, however, give a unique look into chemical warfare on a small scale.

Bioavailability & pharmacokinetics of anthocyanins from cranberry juice

by Colby in

Recently, I wrote why “super” fruits are no better than regular fruit.  Among those reasons, is because constituents in fruit have other discovered roles beside functioning as antioxidants, and in vitro antioxidant activity does not measure these.  I do not think antioxidant activity is a major reason why fruits are good for us.
A recent study [...]... Read more »

To Improve Girls' Science Scores, Show Them Women Scientists

by David Berreby in Mind Matters

Standardized tests are supposed to measure innate abilities. The subject of your last conversation, the lead story on the news last night, the pictures on the wall at the test site—this trivia is presumed to have zero impact on your score in geometry or chemistry. Trouble is, it's increasingly clear that this presumption is simply false. Case in point: This study, published in last month's Journal of Social Psychology, which erased the usual gender gap in high-school chemistry ........ Read more »

Whales, Dolphins, and Human Rights

by Jason Goldman in The Thoughtful Animal

The perspective that whales, dolphins, and other such marine mammals should be afforded "human rights" has surfaced again.

I thought I'd revisit a post I wrote about this several months ago, from the archives, when this first hit the news after the AAAS conference in San Diego. So here's a modified, updated version of the original post.

The blogosphere is all a-twitter with talk of the recent commentary in Science that dolphins should be considered people. Well, sort of people. Non-human peopl........ Read more »

Mindreading by looking at the eyes: do we improve as we age?

by NeuroKüz in NeuroKüz

Do you think you’re good at understanding people by looking them in the eye? This skill is not only important for making money playing poker but for social situations, relationships and everyday professional interactions.Recently, scientific interest in mindreading by looking others in the eye has increased, mainly within the context of ‘theory of mind’ – the general capacity to understand one’s own and other people’s mental states (e.g. emotions, desires, beliefs). A test that is co........ Read more »
