More than you missed …

Yet another collection of interesting and/or curios items you may have missed, starting as usual with the more scientific stuff.
I’m trained as a chemist, so chemicals have meanings for me. But most people hate the word “chemical”. Why? Everything is “chemical”!
And here’s some news about real chemicals, as dispersed in the Fukushima disaster. First there’s a scientific piece showing the truth about the ocean radiation from Fukushima – nothing like what most are saying with false images. Secondly a forthright and slightly worrying piece about the challenges of sorting out the stricken Fukushima reactors — yes it’s a daunting task, but one that should be perfectly achievable. But in all this let’s remember that (a) this was an accident born not of poor planning rather than technological failure in which no-one was killed by radiation and (b) there real disaster is the humanitarian one of people killed and displaced by the tsunami itself and those who are worrying themselves sick about a relatively tiny radiation risk. Which is not to say it isn’t a pretty mess!
After which shit in space seems quite tame!


From shit to … shitty smells made by our domestic wolves. Scientists are getting interested in the composition of dog farts.
More than that, it seems dogs connect us with the wild in ways we maybe don’t realise.
But then cats are sneaky. Far sneakier than we knew. One species of South American Spotted Cat has been disguising itself as a totally different species.
Here’s an interesting look at ten ways in which an ant’s nest is like your house. And it isn’t that far fetched. You have quite a des res really!
From ants to … bacteria (and yeasts). It seems likely that a large part of the taste of that wine you love is down to the differences in the microbial ecology of the vineyards.
A few days ago the Guardian fashion blog looked at the question of nudity for the over-50s. Seems it is much like for anyone else: some have hangups and some don’t. But I still don’t get the problem with nudity.
Moving on from humanity to the humanities, the British Library was recently moved to write a blog post about the need for the recent closure of the Newspaper Library at Colindale. OK so there are good reasons, but why is there no replacement?
And still on history, the Londonist looked at the secret history of the London Brick.

And finally, I have to leave you with some stunning images taken by crane driver working on one of Shanghai’s tallest skyscrapers. Some of them are just breathtaking.

Weekly Photograph

This week’s photograph is one I took just over three years ago, on a November early evening. We were driving south down the A11, across Thetford Chase and looking almost directly into the sunset. As I wasn’t driving I had my camera at the ready, especially as I know this little group of trees often stands out and I always seem to take shots of them. As luck would have it I managed to get this shot as we drove past — quite tricky; it’s really a question of putting the camera on “burst” and keeping your finger down while driving on by. I’m not sure if this shot will even be possible now as this is the last single carriageway stretch of the A11 between London and Norwich and is currently in the process of being upgraded — the new road line may not work as well photographically.

Words: Xylem and Phloem

At last a pair of botanical words!
Xylem and Phloem are the two types of tissue in plants which transport food and water around the plant.
Xylem [z-eye-lem]
The supporting and water-conducting tissue of vascular plants; woody tissue.
This is the network of tubes through which the plants move water from bottom to top. It also forms a large part of the woody (supportive) structure of the plant. It is concentrated in the centre of the stem.
As might be expected the derivation is from the Greek ξύλον, wood.


Phloem [flo-em]
The food-conducting tissue of vascular plants.
The network which transports food (mostly sugars) from the leaves where they are produced by photosynthesis to the growing tissue.
The phloem is softer tissue that the xylem and occurs mostly in the layer just under the bark where the latest “tree ring” is growing.
Again derived from the Greek: ϕλόος = ϕλοιός, bark + -ηµα (passive suffix).
All (vascular) plants, ie. the vast majority we meet in daily life, conform to this basic model even if they appear to be soft rather than woody. However as you would expect the reality is a lot more complex than the above explanation!

On the Passing of Nelson Mandela

Aside from the obvious (well who’d have guessed he was about to die?) here are a few thoughts on the passing of Nelson Mandela.
Let us remember that, in today’s values, Nelson Mandela was first a terrorist leader, and (whether rightly or not) he was convicted of such.
Had he lived almost anywhere but South Africa he would have been locked up for life without any prospect of a get out of jail free card. As, in fact, he was!
That he did get out of jail is largely down to the dysfunctionality and instability of South Africa at that time.
Mandela made the most of the opportunity and turned it to good, which was no mean achievement!
Consequently I suspect that until now South Africa has held together as well as it has because of his very presence. He may no longer have had any formal power, but his influence would, I’m sure, have been very real. And who knows what mafia-esque machinery turned behind the scenes?
I sincerely hope South Africa continues to hold together, return to stability and becomes a respected African nation again. However I fear that it won’t.
There seems to be a big danger that the factional infighting and feuds, which are still there, will surface in what is an inevitable power vacuum. And that this will lead to a descent into anarchy and civil war, if not an outright tribal bloodbath — black vs white, Xhosa vs Zulu etc. Which is much the route trodden by their neighbour Zimbabwe, amongst others.
I hope I’m wrong. The South Africans have invested too much in getting this far to even contemplate such horrors.
