So soon already here’s another round of links to items you may have missed the first time — with rather less difficult science in this issue!
NASA have recently had a spacecraft whizzing past Pluto and they have some stunning pictures as a result, like this jaw-dropping colour image.

Do skin moisturisers do any good? Well maybe. Here is something on how they work.
On a slightly different chemical tack, why is it that many people think blackcurrants smell like cat wee? For me it isn’t the fruit itself that has this effect but the leaves of blackcurrants and flowering currants.
Girls, now do just be careful because it seems that semen has controlling power over your genes and behaviour (at least when it’s applied in the place Nature intended for it).
While on things sexual … just why do we kiss, when most other animals don’t?
Moving slightly away, here are some good scientific reasons why you should go naked. It’s basically what I’ve been saying for many years.
Now what about our pussies? Just why do cats purr? And for me even more interesting is how do cats purr?

Which leads us back to the age-old question: are cats domesticated or still really wild animals?
George Monbiot has been talking about rewilding for a long time, and it is something which does seem to make a lot of sense. In welcoming the new environmental organisation Rewilding Britain, Monbiot spotlights 15 species which could be brought back to rewild these islands.
The hope is that rewilding is not just good for the environment (for instance lynx would easily control our exploring deer population) but that it will enhance and enrich our lives too.
But hopefully one thing rewilding wouldn’t do is to increase is Mother Nature’s ability to rain frogs and other creatures.
From ecology to, well I suppose ethnology … What is the smallest language which would be useful? Well the constructed language Toki Pona contains just 123 words and really does allow you to say (almost) anything.
And now to a few things historical … A rare medieval gold ring depicting St George has been found in Norfolk. I’m glad the archaeologists know it shows St George, ‘cos it sure as hell beats me.
There has been much in the media recently about British slave ownership in 17th to early 19th centuries. Here the Guardian looks at the history and also the Legacies of British Slave-ownership database which is going to be very interesting for genealogists.
And coming slightly more up to date, I bet you didn’t know much of the history of that British institution the red post box. And yes, they were introduced by author Anthony Trollope, who also lived for some years in my home town.
Now we’re reaching the end of our quest and the penultimate curiosity is that a musician has recreated Leonardo da Vinci’s piano, and it is heard for the first time 500 years after Leonardo sketched it. And no, it isn’t All Fools Day — just have a listen to the video; it could easily be a string quartet.

And finally, just because they are stunningly beautiful, here’s a collection of animated GIFs of some gorgeous cactus flowers. Real natural fireworks!
