Chemistry World Christmas quiz, day 10

Posted on December 14, 2012 by Danzig

The leaping lads clearly have a surfeit of Christmas spirits!

And on the tenth day of Christmas we pushed on with the topical news quiz. Today’s questions to stretch your synapses to breaking point are:

Which research group made history in April by using a 3D printer to create their own personalised reaction vessels that actually influenced the course of the chemical reaction?

This year chemist Pete Wothers is giving the Royal Institution Christmas Lecture, but who gave the first RI Christmas Lecture? For those who listen to the podcast.

The answers to yesterday’s quiz are as follows:

Phillip’s annoyance with Mary Berry and the Great British Bake-off was down to the programme’s erroneous explanation of how caramel forms. You can read the problems with their explanation here. The seven minutes of terror Nasa scientist, John Grunsfeld, was referring to was the loss of radio contact while the Mars probe Curiosity was passing through the Martian atmosphere to successfully touch down on the Red Planet.

Chemistry World Christmas quiz, day 8

Posted on December 12, 2012 by Danzig

Today’s topical Christmas chemistry quiz is brought to you by the number eight – in this case the number of women employing an outmoded and romanticised vision of the collection of a dairy product.

On with the show.

What was discovered to have grown slightly this year to 8.2 million square miles in size?

If you’re celebrating Christmas or New Year with champagne, how much carbon dioxide is released from a standard 750ml bottle?

Chemistry World Christmas quiz, day 9

Posted on December 13, 2012 by Danzig

The aforementioned ladies

And on the ninth day of Christmas… my lawyers advised me against making sexist jokes pertaining to the dancing ladies in question. Today’s questions to stretch your memory and your chemical knowledge are:

Why was Chemistry World‘s mild-mannered Phillip Broadwith shouting at queen-of-jam-tarts-and-kindly-old-lady Mary Berry, who presents the programme The Great British Bake-off?

What was Nasa associate administrator John Grunsfeld referring to in August when he said: ‘The seven minutes of terror has turned into the seven minutes of triumph’?

And finally, the answers to yesterday’s quiz. It was the ozone layer that had grown slightly in size. Warmer temperatures have been blamed for the slight increase and the hole is not predicted to return to its 1980s state until 2065. An amazing 5 (five!) litres of carbon dioxide escape from every bottle of champagne. Have a look at our Christmassy feature, Raising a glass to champagne, to learn more. We’ll see you tomorrow at the same chem-time, at the same chem-place.

Nature and Nobel double whammy for Kobilka

Posted on December 10, 2012 by Danzig

Brian Kobilka

Brian Kobilka is probably having a pretty good day today.

Not only is he in Stockholm delivering his Nobel lecture and settling down for a banquet with the Swedish royal family as he picks up his medal for this year’s Nobel prize in chemistry, but he has a paper in Nature today as well.

Is this timing purely a coincidence, or a subtle tribute on the part of the Nature editors? The more cynical among you may call it good marketing, but I’d like to think of it as a metaphorical doff of the cap.

Kobilka, a relatively press-shy academic from Stanford University in California, US, was thrust into the limelight in October when he shared this year’s chemistry Nobel with his former mentor, Bob Lefkowitz. You can read more about the pair and their work on G-protein coupled receptors (GPCRs) in my feature article.

The latest paper is yet another in a long line of GPCR structures that Kobilka and his team have solved, showing protease activated receptor 1 (PAR1) bound to cancer drug vorapaxar. The drug binds very strongly to the receptor, and the structure throws a little light on why that is.

I hope all this year’s Nobel laureates enjoy today’s festivities, it is certainly a well-earned party!
