The Conservation Horizon

by jebyrnes in I'm a chordata, urochordata!

Every so often, a conservation problem rears its head that, upon reflection, we realize we had some inkling of even decades ago. Global warming, biofuels, overfishing, etc. The information was there, but scarce, buried in obscurity, or seemingly counterintuitive. Why not try and recognize the crucial questions early, before the lobster is [...]... Read more »

Surf's up!: How rafting lemurs colonized Madagascar

by Laelaps in Laelaps

A ring-tailed lemur (Lemur catta), photographed at the Bronx Zoo.

Who doesn't love lemurs? The strepsirrhine primates, or wet-nosed cousins of ours, are favorite documentary subjects and extremely popular zoo attractions. And, in one of those bits of zoological trivia that everyone knows, lemurs only live on the island of Madagascar off Africa's southeastern coast. The question is how they got there.

Documenting the paths of animals during geological history is not an easy task. In the da........ Read more »

I got the word daft published in the British Medical Journal

by Lorimer Moseley in BodyInMind

Often, when you publish something in a reasonably posh journal, your mates right you a little email to say congratulations. However, if you write a word like 'daft' in an article that is published in a posh journal like BMJ, it is not just your mates who say congratulations! I got about 40 emails from people I have never heard of over this one. What, exactly, drew such a word out of me? Well it is idea of the placebo being a mysterious, almost magical thing that just happens sometimes. I wrote........ Read more »

Weekly Dose of Cute: Baby Tern

by Christie Wilcox in Observations of a Nerd

The Hawaiian archipelago has a lot of amazing and adorable creatures. Here's a great shot of a baby white tern, or Manu-o-ku, c/o my lab mate Tonatiuh. It was taken by National Geographic explorers in 2005 while they were in the Northwestern Hawaiian Islands.

When people think of Hawaii, they think of the 8 main islands where people live, but the archipelago stretches another 1,200 miles and includes many islands and atolls with vibrant coral reefs and amazing wildlife. This area is so special ........ Read more »

The strange poison of the Platypus

by Lars Fischer in EuCheMS 2010 Blog

The duck-billed Platypus is such an odd creature that one could get the idea that its survival depends on potential predators laughing themselves to death, but in fact it can rely on a far more potent defense. It carries a venomous sting on its hind legs. Envenoming by a male Ornithorhynchus anatinus causes not only [...]... Read more »

Camel vs Jellyfish: a battle with green fluorescence

by 96well in Reportergene

Does the spectral properties of GFP can be modulated by antibody-derivatives? To explore this hypothesis, Axel Kirchhofer and colleagues from Munich Center for Advanced Photonics have designed a number of NanoBodies (NBs) to bind to GFP. (Nanobodies? They are small, antigen-binding, single-domain polypeptides derived from some camelid antibodies). The authors found NBs could increase or decrease GFP fluorescence: in fact, co-chystallization of GFP-NB complexes revealed NBs inducing subtle chan........ Read more »

Private investigations

by Richard Grant in Faculty of 1000

One of the really great things about science is its potential for self-correction. If you have an hypothesis, a result (strange or otherwise), a set of data, it can be tested by anyone. This is encouraged, in fact: when you publish you’re not just saying ‘look how clever I am’ but also ‘here’s something new! [...]... Read more »

Partner’s Picture Prevents Pain

by eHarmony Labs in eHarmony Labs Blog

Another reason why staying socially connected to your loved ones is so important: pain reduction. Looking at photos of one’s significant other during physically painful situations reduced perceptions of pain. Partners are often thought of as being a pain, but in this case, their photo might prove to be the opposite!... Read more »

The Sweet Taste of Cannabinoids

by Neuroskeptic in Neuroskeptic

Every stoner knows about the munchies, the fondness for junk food that comes with smoking marijuana. Movies have been made about it.It's not just that being on drugs makes you like eating: stimulants, like cocaine and amphetamine, decrease appetite. The munchies are something specific to marijuana. But why?New research from a Japanese team reveals that marijuana directly affects the cells in the taste buds which detect sweet flavors - Endocannabinoids selectively enhance sweet taste.Yoshida et a........

What the hell are these things?

You know the drill, I find a paper detailing some wonderful discovery, waffle a bit of background and then give a glib summary of the conclusions.

"A Local Maxima method and a Fair Dispersion Normalization for extracting Multi-Word Units from corpora" by Ferreira and Pereira

Scared face processed more quickly when seen out of the corner of the eye

by BPS Research Digest in BPS Research Digest

The brain processes fearful faces more quickly when seen out of the corner of the eye than when viewed straight on. Dimitri Bayle and colleagues, who made their finding using magnetoencephalography (MEG) brain scanning, believe this bias has probably evolved because threats are more likely to come from side-on.Eleven participants had their brains scanned while they judged whether faces on a computer screen were happy or not. Unbeknown to the participants, each of these visible faces was actually........ Read more »

Amazonian agriculture analyzed

by Jeremy in Agricultural Biodiversity Weblog

I don’t know about you, but in my laziness I often catch myself making the assumption that a centre of crop origin is also one of crop diversity. That is of course sometimes the case, but by no means always, as Vavilov himself recognized. A recent open access paper in Diversity makes the point very [...]... Read more »

How risky is a home birth? Some thoughts about the number crunching.

For some time now, there has been a heated debate in Australia about home births. Home birth advocates argue that a woman should have the right to choose how to give birth to her baby and if she chooses to have a home birth, that choice should be supported by providing the her with adequate [...]...

The Supposed Linguistic Evidence for the Spread of Agriculture

by teofilo in Gambler's House

The prehistoric peoples of the American Southwest were agriculturalists.  Different societies may have calibrated their mix of farming, hunting, and gathering differently, but they all seem to have done all three eventually, and for most it’s quite apparent in the archaeological record that farming was the predominant method of subsistence.  The crops they grew were [...]...
