by Lars Fischer in EuCheMS 2010 Blog

With increasing demand for effective separation of small-molecule gases – think of carbon caption and storage – there has been a lot of research recently into strategies and materials suitable for those applications. The traditional way to separate gases like nitrogen, oxygen or carbon dioxide is to freeze them out one by one, which is [...]... Read more »

the media finds life on titan. sort of…

by Greg Fish in weird things

Around the web, headlines are buzzing about alleged evidence for life on Saturn’s biggest moon Titan, citing a paper which noted a suspicious lack of hydrogen build-up in the lower atmosphere and listing among many a mundane explanation, the possibility of methane-based life. Now, while on this blog I discussed that it’s not impossible to [...]... Read more »

…Just hook it up to my veins!

by Rift in Psycasm

In a previous post I reported that ‘fascinating stimuli’ are potentially better at restoring attention/vigilance than non-fascinating stimuli (Zainaghi and Bettella, 2009) [here]; and that, in my opinion, this was more effective than going and spending time observing natural settings (Berman, Jonides and Kaplan, 2008) [here]. We’ll in looking at that I’ve tried a few [...]... Read more »

The neuroscience of birdsong

by NeuroKüz in NeuroKüz

I’ve decided to write a couple of articles on a relatively underappreciated area of neuroscience: the study of birds. I hope to demonstrate that although the term “bird brain” is used as an insult in everyday bicker, the tiny brains of birds are more complex than they are perceived to be. Bird brains may even be able to teach us a thing or two about the brightest of human brains. In this first post, I will describe birdsong – a rare example of music production in nonhumans.You’ve proba........ Read more »

Copepod Power

by Kelsey in Mauka to Makai

It’s human nature to think of the big bad animals that eat other animals as powerful and the animals that get eaten as wimpy. Of course, humans are often wrong (see “clusterf**kery”). Copepods get eaten by lots of animals—even by critters like jellyfish and right whales, which are known for their lack of speed—but they’re [...]... Read more »

Group-based CBT for pain in primary care

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I briefly discussed yesterday the content of this six-session group-based cognitive behavioural approach for chronic pain, delivered in the community. Today I want to look a little more closely at the way the programme was delivered and how the findings might differ from what happens in New Zealand. To refresh your memory, this is a … Read more...

Library preparation for ChIP-Seq

by epibio in EpiCentral

While Epicentre’s novel Nextera™ technology is revolutionizing next-generation sequencing library preparation, many laboratories are still using older methods of creating genomic DNA libraries for next-generation sequencing. A recent study (Cheung et al.*) of transcriptional regulation mediated by trimethylated histone H3K4 used ChIP-Seq analysis in samples obtained from the human prefrontal cortex.Preparation of the ChIP-Seq libraries involved several Epicentre products: the End-It™ DNA E........

Pollen gathering face brushes

by Africa Gomez in BugBlog

Most non-parasitic female bees collect pollen as well as nectar to provision their brood cells. Pollen is brushed from the plant anthers using their front legs and stored on specialised structures on the bee body or legs. Some bees, however, specialize on collecting pollen from flowers with raised anthers, which touch over the bee's head or thorax when bees land on them. These are called nototribic flowers and include species from the Lamiaceae (the mint family) and Scrophulariaceae (the figwort........ Read more »

ResearchBlogCast #8: Protecting the Environment While Reducing Poverty

by Dave Munger in News

Some of the most bio-diverse areas of the world are also some of the most impoverished, which is why it can seem cruel to create national parks and other protected areas to preserve these ecosystems. Aren’t the human lives in those regions more important than plants or other animals? Some research has supported the idea [...]... Read more »

Heart Patients, Listen Up: Mediterranean Diet to the Rescue

by Steve Parker, M.D. in Advanced Mediterranean Diet

The Mediterranean diet preserves heart muscle performance and reduces future heart disease events, according to Greek researchers reporting in the American Journal of Clinical Nutrition, May 19, 2010.
Reuters and other news services have covered the story.
The Mediterranean diet is well-established as an eating pattern that reduces the risk of death or illness related to cardiovascular disease—mostly heart [...]... Read more »

New data suggests one in two of us experience mental illness in our life-times

by BPS Research Digest in BPS Research Digest

Mental health charities and campaigners typically claim that one in four of us will experience a mental illness at some point in our life-times. This prompts disbelief in some quarters. The rates can't possibly be that high, so the argument goes, there must be something wrong with the figures. A new study led by Terrie Moffitt confirms that 'Yes', there is something wrong with the one in four figure - it should be one in two!Previous estimates for the prevalence of mental illness are largely bas........

PubMed versus Google Scholar for Retrieving Evidence

by Laika in Laika's Medliblog

A while ago a resident in dermatology told me she got many hits out of PubMed, but zero results out of TRIP. It appeared she had used the same search for both databases: alopecea areata and diphenciprone (a drug with a lot of synonyms). Searching TRIP for alopecea (in the title) only, we found a Cochrane [...]... Read more »

Female jumping spiders fight to the death

by Katie Kline in EcoTone

Male jumping spiders (Phidippus clarus) size one another up before engaging in a fight—whether the aggression is based on rights to mating or territory—and in many cases, the pre-fight displays are sufficient to deter physical contact. The males do not nest but instead wander between female nests looking for opportunities to mate. The females, on the other hand, are not nomads—they build nests from silk and leaves in which they wait while they draw closer to sexual maturity.

New Study Suggests That Some Sauropods Reached High for Leaves

by Brian Switek in Dinosaur Tracking

How high did the sauropod dinosaurs hold their heads? It is a simple question, but for years it has been part of an ongoing controversy about the evolution and habits of these long-necked, large-bodied vegetarians. Depending on whom you ask, sauropods either kept their heads down to vacuum up low-lying vegetation from a wide area [...]... Read more »

Testing tests

by sciencebase in Sciencebase Science Blog

Teaching is meant to help students learn, usually about a specific subject, but more broadly about social interactions, working in a team, under duress, about life in general.
