Nature’s Legs

2 Comments

A few days ago I spotted a mosquito on the bathroom wall. Now we’ve all seen mosquitos before but on this occasion I was fascinated by it’s size and anatomy – especially its incredible legs; thin as the finest silk thread.

Culex mosquito
Culex mosquito

How does Nature make such structures – and make them functional? Scientist though I am, it baffles my brain and I can quite see why some people believe in “intelligent design”.

Surely those legs cannot be anything more than stiff supports. Insects have an exoskeleton in contrast to our endoskeleton. The legs need nerves, muscles and circulation to make then more than fixed supports. Legs can move, allowing their owner to walk, clean itself, and even jump. The muscles have to attach to the inside of the exoskeleton, and there have to be nerves – and a method of supplying energy – to trigger them into action.

Insect circulation doesn’t work the way ours does as they do not have hearts: basically they use haemolymph which can diffuse around their small bodies, or be pumped by, for instance, muscular membranes. Some insects use this as a system of hydraulics, in combination with the muscles, to move legs etc. – apparently muscles to move a joint one way, and hydraulics for the reverse. All of which must be under some form of nerve control – and they don’t have that many nerves running from their tiny brains.

Even more weirdly, some insects (eg. jumping spiders, plant hoppers) have a system of gears which work their legs. Crazy or what?

two rice brown plant hoppers
Rice brown planthopper

Just how can these structures be created? You would think they’re so tiny they cannot be even one cell thick – but they have to be many, many cells thick. Which just goes to show how tiny our cells are.

I know evolution has had billions of years to achieve its designs, but I still struggle with how any living thing works or has evolved. Yes, I know the theories, and I can understand it as abstract pieces of mechanics and chemistry. However I really struggle coming to terms with how it all evolved, how it all works – together – and the sheer complexity of living organisms. When you think about it, it really shouldn’t be possible.

Astronomers have now discovered 128 previously unknown moons of Saturn. It begs the question: how large does a rock have to be to be called a moon.

Another big rock, the asteroid Bennu, turns out to be a lot weirder than it was thought. [££££]

And there’s another very odd small rock (below), a meteorite, which appears to be the relic of a lost planet. [££££]

Lastly in this section, Prof. Christina Pagel paints a gloomy dystopian picture of the possible future of British science.

So once more, somehow, another month passes and we come around again to this month’s selection of links to items you didn’t know you didn’t want to miss!

Science, Technology, Natural World

Starting here, it’s all downhill, because it seems that a lot of science is actually faked.

Fly brains may be tiny in size but they’re still stuffed with very complex inter-weavings of thousands of neurons, so it’s amazing that researchers have managed to map every neuron. Two reports, first from BBC, and second from Scientific American [££££].

At a different level, scientists have analysed ancient DNA to unravel how the endangered Iberian Lynx avoided extinction.

Some fish in the sea are so bizarre … here’s one that walks on six legs, and those legs can smell its prey in the sand. [££££]

Still at sea, but now above the water, research has found that the windless doldrums around the equator are caused in a completely different way than previously thought.

Staying with things geographical, apparently Mount Everest is still getting taller and not quite in the way we might expect.

It’s no great surprise that scientists have found that the asteroid which wiped out the dinosaurs was not a one-off.

And talking of meteorites, there was a mega meteorite about 3 billion years ago which was at least the size of Greater London which boiled the ocean and created a 500km wide crater.

NASA has shut down one of Voyager 2’s five remaining instruments to save power.

And finally in this section, did the early universe balloon in size with “cosmic inflation“, or is there a much simpler explanation?

Health, Medicine

This month’s medical matters are all to do with reproduction, in one way or another …

There are many genetic changes that link puberty to other aspects of physiology and affect its timing.

Prof. Christina Pagel highlights why we need to stop ignoring period pain and heavy bleeding!

Why is it that many doctors don’t believe women about the menopause? [££££]

At which point the Guardian asks if wearing a bra makes breasts more perky.

Let’s segue away from “women only” … in a move labelled “bonkers” by many, an NHS hospital in Norfolk has instructed staff that they must not describe babies as “born” male or female [££££]

And finally to the morgue where pathologists have found, during an autopsy, that the deceased 78-year-old man had not two, but three penises – and it is only the second ever such report and the first in an adult. Two reports, from Popular Science and Gizmodo. And the published academic papers make interesting reading!
