First up was a story on diffusion tensor imaging (DTI) and how it’s used to “see” water diffusion in the pain sensing areas of the brain. This was used recently in a German study on people who had chronic lower back pain but without any discernable cause. See the Radiological Society of North America’s website http://www2.rsna.org/pr/target.cfm?ID=300
Second was the discovery by Claude Herzberg that the Earth recycles quite a bit of its own crust after subduction. Herzberg reports in Nature (Nature 444, 605 - 609 (30 Nov 2006) Letters to Editor) that the chemistry of Hawaiian magma has low calcium levels; something you’d expect in recycled crust. Further studies on the content of sulphur and other chemicals could tell us more about the cycles that volcanoes go through.
In the middle of the show was my soap box section where I editorialised (read ranted on and on) about the recent report by Ziggy Switkowski et al. on the potential nuclear future for Australia and the implications for water. There have been several other reports that have also come out and reports in the press (ABC) and I just though I’d put all these numbers about gigalitres and gigajoules in perspective with my own extraction from the ABS Water Accounts 2004-05, Table 1.3, page 8. The numbers I quoted were that 25 nuclear power plants using around 25 Gl of water a year each (total of 625GL/year), would use more water per year than the water consumption of every household in NSW (572GL/year). In fact, if you add together the household consumption of Victoria, South Australia, Tasmania and the ACT that’s approximately 649 GL/year. So, all these nuclear power plants had better be on the coast right? Well that’s not exactly specified in the Zwitkowski report, probably because the current transmission lines emanate from coal fired power stations plonked next to rivers and lakes. Hmmm.
Next up was a story on epigenetics and DNA methylation which was derived from the AAS website (http://www.science.org.au/nova/098/098key.htm).
And finally a story left in the fridge from last week’s Food Theme Show: asparagus and why it makes your pee pong. All you want to know about asparagus but were too afraid to ask can be found in the journal article; Drug Metabolism and Disposition vol 29. No.4 Part 2 p539 (2001).
Fuzzy Logic Producer’s Report for 26th November 2006
The Food Themed show had some tasty science. While veering decidedly towards the cheesy, there was a smorgasbord of food facts and, just to prove it IS possible, we never mentioned chocolate.
Waste olive oil put to good use
New strains of wheat provide better nutrition
Edible cotton (seed)
Cheese in a can! Actually, Dean went about deconstructing the cheese in a can and found that there’s a whole bunch of things other than cheese in those cans. For more information on what the numbers indicating food additives really mean try starting here http://www.foodstandards.gov.au/foodmatters/foodadditives.cfm .
Genes, tolerance and tastebuds. Jeevan delves into the link between your dinner and your DNA: why some people can handle chilli, cow’s milk and alcohol (occasionally at the same time!) while other’s can not. More information in the book “Some Like It Hot” by Gary Paul Nabhan.
Interview with Bruce Chapman from Jones the Grocer in Manuka about cheese making throughout history and throughout the World. Incidentally the Spanish cheese washed in a local red wine that Bruce mentioned in the interview was fantastic. Want to know more? Try http://jonesthegrocer.com/
How to make cheese: The quick and simple way to coagulate milk with vinegar. It doesn’t exactly happen in front of your eyes but it does happen. This was a (first ever?) Fuzzy call out to listeners to actually perform an experiment with instruction over the air. When tried at home I found small lumps of “cheese” did actually drop out of the milk – after some stirring, for some time. A much better bet would be to use rennet as they do in regular milk production. Don’t know what rennet is? Try http://en.wikipedia.org/wiki/Rennet .

Professor Srinivasan's work has contributed significantly to our knowledge of how insects solve complex navigation problems with such apparent ease, despite possessing a brain the size of a pin head. He has concentrated mostly on the vision system of the honeybee, which is known to be highly specialised to the tasks it performs. Perhaps the most significant lessons learnt from this work are that you can achieve a lot with a small amount of computing power, which is why robotics researchers are so keen on insects. Srinivasan was one of the first to implement insect-inspired navigation strategies on robots equipped with cameras. This is now a well established field of robotics research, and has helped bring robotics research forward many years, after a long time spent getting seemingly no where.

More (including whole shows) coming soon.
Contributors: Dean, Kate and Jeevan
Today’s show was somewhat dominated by Dean’s hangover. He was determined to check out if some of the accepted hangover cures actually work – but more on that later.
The show started normally enough with our newsy bits:
• a new supernova has broken all the rules, scientists are confused
• sunless tanning
• Indonesian blrd flu toll hits 50
• Doubts over the efficacy of the morning after pill (for social reasons, not medical ones)
Then, in true Fuzzy style, we started talking about sex:
• the world’s first penis transplant has taken place, but was removed two weeks later after his wife freaked out
• crickets face the dilemma of calling for a mate, but becoming prey for a parasite if they do (shag and die, in other words)
• adult male prairie dogs are being taken by predators because they’re so preoccupied with sex (again, shag and die)
• hope for a new IVF technique
• and we couldn’t help but wonder what the first female space tourist was doing while she was up there…
We talked about hangovers – what they are medically, how they happen and why you feel so bloody awful when you’ve got one. Dean was testing the fatty-morning-after-breakfast cure, as well as a sports drink to try and rehydrate whilst replacing lost electrolytes. By the end of the show, he reported feeling “much better” but I can’t help but wonder if that had more to do with his scintillating company than anything he ate or drank.
The science contained with reports of spinach in the US being contaminated with E. coli and killing people; I had serious food poisoning last week from I don’t know what, so I had HUGE amounts of sympathy for anyone affected. The spinach story tied in with a recent ruling by the Queensland DPI that processed effluent can be used on food crops.
A huge storm cloud study in the Northern Territory will have big impacts by improving weather forecasting. And the Bureau of Meteorology calendar goes on sale this week.
Getting towards the end of the show, we hit what I like to call our science slam (headlines to fit in the stuff we didn’t have time to talk about in detail):
• development of a new intestinal robot
• discovery of a 3.3 million year-old juvenile Australopithecus skeleton (dubbed Lucy’s baby)
• Guidance being provided for people buying groceries online
• Naturally dead embryos yielding stem cells
• The Australian Medical Association backing calls for adding labels to alcohol warning that it causes cancer
• A new ring has been discovered around Saturn

We completely threw out the standard Fuzzy Logic format and decided to rely on our natural wit, talent and vast knowledge of lots of useless things to have an hour-long conversation based loosely around the Australian Science Festival.
With this in mind, we made a huge list of the things we wanted to talk about then competed to see how to segue them together in the most creative way.
It ran something like this (spot the connections if you can):
- Maths writing competition
- Importance of the invention of the number zero – incidentally by an ancient Indian civilisation
- Decimal versus older measurements
- A foot is the distance between the crease of your elbow and your wrist (complete with on-air testing of said theory, contortions of feet to arms) – and the realisation that Bec’s not quite proportioned like that (she's quite tall, whereas I'm fairly short).
- Marfan’s syndrome and Da Vinci’s Vitruvian man
- I was then going to a break and called myself Jacinta by accident, which was a good lead into the National Memory Test as part of Science Week. Everyone (deservedly) laughed heartily at my stupidity.
- Academy of Science lecture on mammals and weird sex
- Alignment and behaviour of sea urchin sperm
- Ultrasounds affecting the brains of unborn mice
- Elevated testosterone levels in athletes – how realistic is Landis’s claim of his not having taken anything?
- Open day at the Australian Institute of Sport and Tidbinbilla tracking station
- Another Mars hoax doing the rounds
- Mars rovers celebrate their birthday (we thought it was their second)
- Sphinx cats with no hair, but colouration on their skins that indicate what their coat colour would have been
- Hippos sweating blood (not really, and we wondered whether it was iron making the sweat red)
- Elephants make their way to specific salt licks to ingest minerals
- Yak’s milk is pink and high fat (v good for high altitude nutrition)
- Magnesium deficiency in cows, importance in muscle metabolism
- Back to coat colours in cats, dogs and zebras – and that individuals zebras can be identified by the stripes on their butts
- Schrödinger’s cat – vague biologist explanation to freak Bec out
- Quantum computing
- Fire research at CSIRO and fire-proof ceramics
- Roundup of Science Festival events for the coming week
- Tobin Brothers open day – respect for the dead
- Skills shortage – broadly based on recently released DEST audit
- Importance of taxonomy in Australian science
I taped the show, the reception is a little rough in patches, but I will look at finding a way to get snippets on the blog.
Much fun was had in the studio – reports indicated that it translated into people’s homes (I know Dean is still laughing that I forgot my own name).

Ably assisted by: (the late) Dean and Brendan
We did a split show this week, with the standard news stories we liked from the week as well as chatting about fears, phobias and anxieties.
- Radio tags can expose surgical mistakes: http://www.nature.com/news/2006/060717/full/060717-5.html
- Antarctic researchers risk bone loss: http://www.csiro.au/csiro/content/standard/ps211,,.html
- Antarctic air link may shock the system: http://abc.net.au/science/news/stories/s1690756.htm
- Why we love the music of our youth: http://www.abc.net.au/science/news/stories/s1688781.htm
- Music to match your mood: http://www.nature.com/news/2006/060717/full/060717-16.html
- Is it really you or jamais vu? http://abc.net.au/science/news/stories/s1689668.htm
Science slam (the quickies at the end of the show):
- Dentists to give hurt panda false teeth: http://go.reuters.com/newsArticle.jhtml?type=scienceNews&storyID=12901098&src=rss/scienceNews
- Breastfeeding 'kills baby's pain': http://news.bbc.co.uk/2/hi/health/5190306.stm
- Scientists battle to save 'last living link': http://www.theaustralian.news.com.au/printpage/0,5942,19859367,00.html
- Bush casts his first veto on stem-cell bill: http://go.reuters.com/newsArticle.jhtml?type=scienceNews&storyID=12897138&src=rss/scienceNews
Our discussion of phobias centred around the fact that we all have a fear of something, even though we know it's irrational and disproportionate to the situation. For me, it's spiders, for Dean it's magpies and Brendan's just plain afraid of losing.
But fear does have its place and the fear of snakes could have driven pre-human evolution. And fear could become costly for those afraid of crossing the Chesapeake Bay bridge in the USA.
There are some strange phobias out there (for a pretty full listing, go to http://www.phobialist.com/), but there is hope for treatments, whether it be using cortisol or D-cycloserine.
This was Dean's first time at the Fuzzy microphone (he previously featured as our Silent Barrell Boy on the second Radiothon trivia show) - well done, please do come back. But no more Manhatten Transfer. Ever.
Wednesday, 19 July 2006
This Sunday on Fuzzy Logic we'll be talking about fear and phobias, so drop us a note in the comments, tell us what your phobia is & we'll try & put a name to it on air.

Mike Watson – ATSB
New asthma pills, decoding genes, genes show gender differences and the effects of olive leaves on cancer
Antarctic winds, more complex vegetation on the way in Antarctica, penguin spies and alchemy by bacteria.
Overall, a great show. Our special guest gave an interesting insight into the world of air crash investigation as well as flying in general. A whole program could have been devoted to the subject. Naomi adding in the event occurring around time is an excellent idea, as there are some great events coming up.
As always, have a great week and take care
