Solar Sea Slugs: Part animal, part plant… or not?

by Prof-like Substance in The Spandrel Shop

Original image here. Sea slugs are far more interesting than their name might imply. Aside from being beautiful, they have some unusual ways of making a living. In the case of a few unrelated species, they steal for a living. A handful of sea slugs have found away to make the most of the algae [...]... Read more »

Bacteria vesicles - SGM series

by Lab Rat in Lab Rat

The SGM autumn conference is now over - thanks to everyone who tweeted it so people like me could catch up on events without actually going. I've just got two more topics of my own little personal blog-conference to go, and this one is going to be on bacterial vesicles rather than secondary metabolism because it suddenly struck me that I don't actually know much about outer membrane vesicles, and this might be a good opportunity to explore them.So this is the penultimate post in my SGM topic ser........

You're (Brain Is) So Immature

by Neuroskeptic in Neuroskeptic

How mature are you? Have you ever wanted to find out, with a 5 minute brain scan? Of course you have. And now you can, thanks to a new Science paper, Prediction of Individual Brain Maturity Using fMRI.This is another clever application of the support vector machine (SVM) method, which I've written about previously, most recently regarding "the brain scan to diagnose autism". An SVM is a machine learning algorithm: give it a bunch of data, and it'll find patterns in it.In this case, the input dat........ Read more »

A Little Education Goes a Long Way

by Shaheen Lakhan in Brain Blogger

The burden of type 2 diabetes is staggering. Close to 20 million people in the United States are diagnosed with type 2 diabetes, and total costs related to diabetes are creeping toward $200 billion annually. Programs to prevent and treat diabetes are numerous, but the effectiveness of various types of programs and modes of education [...]... Read more »

Female Finches Reap the Benefits of Being Unfaithful

by Laura Klappenbach in About Animals / Wildlife

Female Gouldian finches don't always stand by their man. Given the opportunity, they'll indulge in a promiscuous tryst with another male. But this infidelity is not merely cold-hearted cheating. It's an evolutionary ploy that enables the female finches to bolster their offsprings' odds of survival.
The benefits of promiscuity in monogamous animals such as the Gouldian finch are straightforward for males but less clear for females. Promiscuity offers male finches a way to increase the number of o........ Read more »

Why was last winter so cold? And is this a problem for climate change?

by Vivienne in Outdoor Science

The winter of 2009/2010 was unusually cold across most of the Northern Hemisphere, leading to deaths and traffic chaos. Newspapers told lurid tales of planes sliding off icy runways, home-going revellers found frozen to death, and heavy snow and icy roads trapping motorists in their cars all night – and that was just in Britain. Needless [...]... Read more »

Neuro Brain Thermodynamics

by Mike in Brain Stimulant

The brain is a metabolically expensive organ that uses quite a bit of energy. It's no surprise that it also generates a decent amount of heat during this energy usage process. A new paper has come out that poses and answers the question as to whether there is a thermodynamic limit to brain size (evolutionary wise). The author is basically asking how big can a brain get before it becomes too hot to function properly? What sort of constraints does evolution have in constructing a bigger brain,........

How much would climate change if we used existing infrastructure to the end of its life?

by Phil Camill in Global Change: Intersection of Nature and Culture

Here’s an interesting thought question:  How much would global temperature warm if we used only the existing energy infrastructure (i.e., power plants, furnaces, motor vehicles) until these machines reached the end of their useful lives?  Once they died, they would be replaced by devices that did not emit CO2.
Steven Davis and colleagues addressed this question [...]... Read more »

when bad quantum physics invade military news

by Greg Fish in weird things

As said by Futurama’s mad scientist at large, Professor Farnsworth, quantum mechanics mean that anything can happen for any reason or without one. Of course this was really a swipe at how so many of us tend to see the complex physics of quantum objects, and it’s a very valid one since there’s a seemingly [...]... Read more »

Why modeling GPCRs is (still) hard

by The Curious Wavefunction in The Curious Wavefunction

Well, it's hard for several reasons which I have discussed in previous posts, but here's one reason demonstrated by a recent paper. In this paper they crystallized the ß2 adrenergic receptor with an antagonist. Previously, in the landmark publication of the ß2 structure in 2007, the protein had been crystallized with an inverse agonist. Recall that an inverse agonist inhibits the basal activity of the GPCR whereas an antagonist stabilizes both active and inactive states but does not affect the........ Read more »

Why digging up primary sources is important?

by Tommi Himberg in Synchronised Minds

When writing a thesis, a chore that always takes more time than predicted is building the bibliography. Even with good software to manage your citations and references (EndNote, RefWorks, JabRef etc.), peppering your text with references and engaging in discussion with your sources takes time. (I often wonder how it was even possible to do [...]... Read more »

Distressed Soldiers Screaming Inside

by Ultimo167 in Strong Silent Types

Hegemonic masculinity takes a heavy toll on men in the general community but as Green et al. (2010) discover, an even heavier toll on men in the military. The prohibitions against such men speaking up and seeking help for their heightened emotional distress are many, and severe. Tis preferable, it would seem, for male soldiers to suffer in silence than dare to name their psychic torpor. Is this further evidence for the necessity of peace? I say yes, for sure.... Read more »

A Representative Example of a Genetic Study of Longevity

by Reason in Fight Aging!

As the tools of genetic analysis improve by leaps and bounds, the cost falling with each advance, more and more research is taking place into genetic influences on human longevity. This is an enormously complex area of study, and has little to no relevance to any repair-based methodology for lengthening human life. Outside the field of regenerative medicine, most aging researchers do not work on repair strategies such as SENS, however. Meanwhile there is plenty of funding for genetic studies of ........

How vaccines work Pt.1

by James Byrne in Disease Prone

The goal of every vaccine is to induce lifelong protection for the patient from the specific nasty of interest. But in order to understand how one would receive ‘lifelong protection’ following the injection of a dead or weakened nasty, or even just the bits of one, we need to go backwards a bit and have a look at how we develop an immune response....

How do vaccines work Pt. 1

by James Byrne in Disease Prone

Continuing with my sub-series on vaccines this week I am going to have a bit of a look at the theory behind how vaccines do their jobs inside us. Next week I’ll look at how they work at a community level. First it’s worth defining what it is that a vaccine is supposed to achieve [...]... Read more »

Spontaneous fermentation: the role of microorganisms in beer

by Katie Kline in EcoTone

Benjamin Franklin, one of the Founding Fathers of the United States, was once quoted as saying: “In wine there is wisdom, in beer there is Freedom, in water there is bacteria.” While there is certainly some truth to this quote, especially considering water quality in the 1700s, it should be noted that beer’s long history is also fraught with microorganisms—both helpful and harmful in the eyes of the brewer.

Seeing the big picture

by Tom Rees in Epiphenom

Are you a big-picture person, or do you tune into the detail? Surprisingly, the culture in which you were raised - including your religion (or lack of it) can shape this fundamental aspect of your personality.

A decade ago, researchers found that while westerners were relatively faster at picking out the component parts of a picture, Asians were relatively quicker to see the global, holistic components. They reckoned this was an effect of cultural differences - the individualistic Westerners ve........ Read more »
