[…] This exciting increase in the understanding of sphingolipids, from a variety of research fields, remains strong. Some very recent research provides evidence that sphingolipids have a role in the physical process of division in at least one type of mammalian cell [5]. This physical role of this class of lipids is an unexpected contrast to the biological role sphingolipids have as molecular messengers in processes such as angiogenesis, neurodegeneration and diabetes. However it may not be unique; it appears that inositide lipids have both structural and biological roles. […]

Comment on Why is he doing this? by Dave Scott

Dave Scott — Tue, 18 Sep 2012 17:32:12 +0000

Yep, interesting points. The major missed opportunity is to try and differentiate between things we wish to have competency in, such as numeracy and literacy (this was the thrust of Jeremy Hardy’s comments on the news quiz) and things we need people to be graded in so we can see how good they are at it (English, Maths, Science, Humanities, Music, etc). All in all, these appear to be a backwards step from the Coalition.

Comment on Why is he doing this? by Alex Kendall

Alex Kendall — Tue, 18 Sep 2012 15:36:18 +0000

Nice piece. I think you can take this one step back and ask, before why we have exams, why we want formal education for all in the first place. From this I hope we could agree that although finding a job is important, surely a more important primary objective is to develop minds who can think about and have an understanding of the world around them. By this I mean that it’s not purely about facts. Far too much of education has been cramming for exams with little thought as to the real meaning of the knowledge we’re asked to learn. The new system doesn’t seem to get rid of any of this. How I think you solve this is by looking at process more than end result, basically we need to think how education itself needs to be changed, not just the system of examination. Getting rid of coursework (which these changes do) seems a step in the wrong direction. Having separate exam board for each subject will, I hope, lead to greater flexibility for teachers and a wider choice of curriculum, which I think is good. It may not. Fundamentally though, pupils need more time to learn in a way that is about teaching you how to think, not just what to learn.

Comment on W-words, N-words, and Victoria Coren Stealing My Act by Tharun

Tharun — Sat, 24 Mar 2012 14:40:28 +0000

I don’t know about sad and pathetic , but that clmoun is definitely a bit of a mess. Coren seems to think that contacting Santa via Skype is some kind of betrayal of Western civilisation, and I love that wonderfully Freudian line about flaccid, morally limp politicians .On the other hand, he does have a point about Christmas being to some extent a Western thing as opposed to a specifically Christian thing. Europeans were celebrating the solstice well before the advent of the peculiar Middle Eastern cult known as Christianity, and Christmas has always had secular as well as religious aspects. I would argue that celebrating a generic holiday season is indeed an abandonment not just of Christianity but of Western tradition. If we Canadians really want pluralism to trump that aspect of our heritage, then fair enough, but let’s be honest about what we’re doing.Anyway, here’s a bit of irony for you: in Beijing, where I live, nobody calls Christmas the holidays . People seem to be catching on to Christmas as an excuse for a party in late December, and retailers are catching on to it as a way to boost their sales, so Christmas signs and decorations are becoming commonplace. They may say Happy Christmas or even Lucky Christmas rather than Merry Christmas (one year a local shopping mall went with High Christmas ), but you almost never see Happy Holidays or Season’s Greetings . While North America seems to refight the War on Christmas every year, godless, profoundly non-Western Beijing just accepts Christmas as the name of the odd foreign holiday that falls on December 25. It’s quite surreal when you think about it.

Comment on How Hot is Hot? A Burning Question About a Hot Condiment by Paul Scovillophile

Paul Scovillophile — Wed, 01 Feb 2012 15:22:40 +0000

Being an ardent fan of all things capsacin, I grow Bhut Jolokia (ghost) peppers in my garden to use in cooking. I have noticed that these fruits, either fresh, cooked or pickled are not only extremely ‘hot’ to the mouth and stomach, but also cause explosive and watery motions. I’ve eaten many a Scotch bonnet and had equal levels of mouth/stomach burn, but never this level of gastrointestinal disquiet. Is there another compound in these ghosts that might prove useful as a purgative? I’ve had ghosts from three different seed sources and will continue to grow from seed this year. I will also continue in my Scoville related sauce endevours and post up any findings. Keep up the good work with this interesting ‘column’.
