Y Chromosome I: A Brief History

by Kele in Kele's Science Blog

This first post in my Y chromosome series will briefly discuss the history of Y chromosome research. The general outline is derived from the introduction of Skaletsky et al. (2003). I will hopefully fill in the numerous missing parts as the series continues. Anyway…... Read more »

Paul the Psychic Octopus: A watery lesson in understanding clinical evidence

by Lorimer Moseley in BodyInMind

So the World Cup justifiably goes to Spain and it seems that Paul, the now world famous psychic octopus, predicted the results.  In fact Paul demonstrated a seemingly legendary clairvoyant ability.  Wikipedia informs us that he predicted the outcome of all of Germany’s games and the final with unerring accuracy. You may not have realised [...]... Read more »

Reovirus infection of farmed salmon

by Vincent Racaniello in virology blog

Global fish farming may be the solution to the impending collapse of the commercial fishing industry, but penned fish are susceptible to infectious diseases. Infection with salmon infectious anemia virus, an orthomyxovirus, lead Wal-Mart to stop buying farmed salmon from Chile, the world’s second largest producer of the fish. As a consequence Chilean farmed salmon are being immunized to prevent infection. Heart and skeletal muscle inflammation (HSMI) is another disease of farmed salmon, fi........ Read more »

Sponge Genomes: Simply Complex

by Lucas in thoughtomics

You might not think much of sponges. Maybe you feel that they’re only good for rubbing your back and cleaning your kitchen sink. While you’re absolutely right that sponges have to be admired for their absorbing qualities, they have much more to offer this world. Like on the front of early animal evolution: [...]...

Bacterial needles and their role in infection

by Lab Rat in Lab Rat

I spent ages over the title of this post. The original paper "Injecting for infection" was my favorite but it isn't wonderfully clear. It sounds like something about dirty needles; bacterial colonies over the surface of injections. In reality it's about something far more amazing, the little needles that bacteria make themselves, in order to inject toxins into the cells that they destroy.Officially these are called Type III secretion systems, as they allow the secretion of toxins (and other thin........

Modern agriculture a major control of increased rates of dust flux from continent to ocean

by Brian Romans in Clastic Detritus

Strong winds can pick up dust particles* from continents and carry them thousands of kilometers where they are deposited on the ocean floor. Deserts are especially important contributors of dust with the Sahara Desert of northern Africa being the single largest source of mineral dust in the world.  The occurrence of this process has been [...]...

Autism And Wealth

by Neuroskeptic in Neuroskeptic

We live in societies where some people are richer than others - though the extent of wealth inequality varies greatly around the world.In general, it's sad but true that poor people suffer more diseases. Within a given country almost all physical and mental illnesses are more common amongst the poor, although this isn't always true between countries.So if a certain disease is more common in rich people within a country, that's big news because it suggests that something unusual is going on.

Spurs and blades on the wings of jacanas, lapwings, sheathbills and archaeotrogonids (clubs, spurs, spikes and claws part II)

by Darren Naish in Tetrapod Zoology

A little while back we looked at the claws, bony knobs and other structures present on the hands of certain palaeognaths, waterfowl and other birds. Time to look at more of this sort of stuff - I kind of got distracted by lapwing taxonomy, so this is all going on for a bit longer than expected, sorry. Anyway...

When ecological opportunity knocks, does adaptive radiation answer?

by Jeremy Yoder in Denim and Tweed

One of the most basic questions in evolutionary ecology is, "why are there more kinds of this kind of critter than that kind of critter?" As in, why are there more than twenty thousand species of orchids, but only one species of ginkgo? Why are there hundreds of thousands of species of beetles, but only four species of horseshoe crab? In a literature review just released online—and my first publication as lead author!—my coauthors and I assess the support for one hypothesis: that species mul........ Read more »

Taung, 2.3 Million Years Ago – Scratched bones and fossil primate teeth as keys to a lost world

On December 23, 1924, the Australian anatomist Raymond Dart chipped away the last bit of rock encasing the skull of a small fossil primate. The specimen had been part of a collection of fossil scraps sent to him from a limestone quarry in Taung, South Africa - not too far from where he was teaching [...]... Read more »

Life and death and sex choices in mantids

by Zen Faulkes in NeuroDojo

If ever there was a time to be careful about who you were going to mate with, it would probably be when there was a good chance you were going to die in the attempt.

And we’re not talking about some sort of heroic situation where the male has to endure hardships to get to the female. We’re talking about situations where the female herself is the threat.

“Fair princess, I have arrived to...”

Carnivorous trees of the sea: Notodendrodes not as harmless as it looks

by Psi Wavefunction in Skeptic Wonder

Remember Notodendrodes and the spicule tree? Don't they look so much like harmless trees sitting around sunbathing like their plant counterparts? Not all tree forams are harmless. The microscopic marine world is full of surprises, like trees waving around their long sticky network 'feet' to trap and devour any traveler that happens by. Here's some wonderful shots of Notodendrodes caught in the act:The top left image shows a clump of Artemia caught by Notodendrodes, a big carnivorous tree foram. ........ Read more »

Honey’s anti-bacterial properties found?

New research suggests that (some of) the secrets to honey’s anti-bacterial properties may have been revealed.

A Dutch team of microbiologists propose that the anti-bacterial properties of the honey they tested come down to four chemicals and one general property:

Sugars High concentrations of sugars have long been known to have anti-bacterial properties and are used in preserving food.

Snakes in a brain scanner!

by BPS Research Digest in BPS Research Digest

Forget snakes on a plane, this was snakes in a brain scanner! To chart the neural activity associated with overcoming fear, Uri Nili and colleagues scanned snake-phobic participants' brains while they chose, with the press of a button, whether or not to bring a live, 1.5M long corn snake, located on a conveyer belt in the scanner room, nearer to their heads, or to shift it further away (watch video). A control condition replaced the snake with a teddy bear.
