just looking

I know, I know, I really don’t need any new hobbies right now. I have to write 5,000 words  about crab shell chemistry by the middle of next month. But that doesn’t mean I can’t look at borrowed and ebayed books about new hobbies I might be interested in taking up if I ever do graduate.

I may have done a little bit of sewing this weekend, including first ever zip installation using my new zipper foot, but if I did the results would be embargoed.

Teaser Tuesday

Still doing very little non-study related reading, so here comes another chemistry teaser …

Ozone (O3) occurs throughout the atmosphere, but only ever in trace amounts.  Indeed, if all the ozone contained in the first 60 km or so of the atmosphere could be brought down and assembled at the Earth’s surface, it would form a layer only some 3 mm thick.

Teaser Tuesdays

I’m spending a lot of time with my text books at the moment, so I haven’t got on to a new reading book and am still reading Guns, Germs & Steel. So this teaser is from my text book.

This folding pattern is known as higher-order structure, and it means that every single molecule of the enzyme will have precisely the same convoluted three-dimensional structure.  The enzyme is held in this shape by hydrogen-bonding, and a number of other intramolecular interactions.

Hope that doesn’t contain too much enzyme-catalysis-related spoiler info for you

Teaser Tuesdays: Trouble with Animals

Sorry for lack of posting this week, I’ve been mostly either working or sleeping.  I think my body is still working on the last of the Irish lurgy, leaving me too tired to knit (!) most evenings.  Anyways, here is the Tuesday teaser, and hopefully knitting productivity will pick up soon.

He wondered what Mum and Dad would think about having a donkey in the house, or at any rate in the garden, especially so soon after the penguin.  On the other hand, Mum had always said he must be kind to animals.

You spend ages looking around for an interesting meme and then two come along at once! Via Penny’s blog I found out about Teaser Tuesdays.

Sounds good to me, here goes this week’s

Early humans certainly didn’t fly by helicopter from Alaska to Meadowcroft and Monte Verde, skipping all the landscape in between. Advocates of pre-Clovis settlement suggest that, for thousands or even tens of thousands of years, pre-Clovis humans remained at low population densities or poorly visible archaeologically, for unknown reasons unprecedented elsewhere in the world.

And lovely Suse has honoured me with an award!  It has quite made my day.  Now it’s my turn to give out some awards, will have to think about that for  a bit ….
