Eau D’Asparagus

There is an old WebMD item about why your urine smells funny after eating asparagus. I only bring it up because the stalky delicacy is once again in season; delicious they are too from our local farm shop. Anyway, the WebMD item mentions that it’s the presence of a sulfur compound known as mercaptan in the asparagus (also found in rotten eggs, garlic, onions and skunk scent) that leads to the smell.

The article says, and I quote: “When your digestive tract breaks down this substance, by-products are released that cause the funny scent. The process is so quick that your urine can develop the distinctive smell within 15 to 30 minutes of eating asparagus.”

I’m not sure they’ve got that entirely straight though, it is definitely a sulfur compound being metabolised that releases the methanethiol giving urine the smell, and most researchers would suggest the amino acid methionine is the source. If it weren’t we’d also talk about asparagus poo as well as pee as the breakdown product would be present in both.

A+ Science Fair Projects

We used to host some great middle school science projects on our roster. If you’re after an A+ science fair project, then one of the best resources you should check out is Janice VanCleave’s books. She offers the scoop on A+ Science Fair Projects and more. And if her style doesn’t suit, there’s always Science Fair Projects for Dummies (no offence!).

Search Sciencebase for science fair projects that can be done in 24 hours or over the weekend. There are also great ebooks out there such as ones with 101 science projects.

Plastic Guitars Strike a Chord

The plastic guitars I originally wrote about in Reactive Reports the chemistry webzine years ago are almost ready for market according to the SciScoop Science News Forum: Plastic guitars strike a chord

The inventors of the plastic guitar, based at Loughbourough University, are showcasing a range of innovative, high-quality acoustic and electric guitars made almost entirely from polymers. The three models, a hybrid wood/polymer acoustic, an all-polymer acoustic and a semi-hollow electric, feature patented foamed polymer technology that gives outstanding sound quality, apparently. Personally, I’m holding out for an Alex Lifeson signature Gibson ES355 in white (of Rush Natural Science fame).

Causes of viral infections

I wrote a report for the Royal Society about one of its discussion meeting on emerging viral infections some time ago, so it’s quite interesting to see that visitors who hit the Sciencebase site via Google are still reaching the site searching for causes of viral infections. I suspect the visitors are after solutions to their own diseases…the main cause of viral infection, I felt like saying in facetious mode, is a virus…

The SARS bacterium?

The journal Chemical Communications forever trying to publicise its papers, recently highlighted a “hot” paper about removing harmful bacteria from an airstream using a titania photocatalyst. That’s all well and good but “LJ”, who wrote the highlight, seems to imply that the inspiration for this works comes in the wake of the SARS outbreak. To quote: “The recent SARS outbreak has triggered concern over airborne bacteria and the diseases they can cause.”

Well, forgive me, but isn’t SARS a virus? The researchers themselves mention Legionella and the virus SARS but LJ presumably felt Legionnaire’s disease was not topical enough to catch the eye of any science writers prowling the Chem Commun hot papers page. Well, LJ, I’m afraid your mention of SARS caught my eye, but for all the wrong reasons.

Killer typo

Regular Google visitor with clumsy typing skills? Watch that you don’t hit the “k” before the “l” when entering the search engine name into your browser address bar, you could be in for a nasty shock. Googkle.com was registered by some phishy customers and if you were dumb enough to visit their site you would be bombarded with trojan sites and all sorts of malware, according to Icelandic computer security company F-secure. Gooogle.com on the other hand will bring you to the Google homepage while Gooooogle.com will send you to a casino site. But, who types in Google.com anyway, don’t most users these days have it bookmarked or run the Google toolbar to access the search engine?

Cyber Skiver

Yahoo has added an intriguing feature to its Messenger software that will have bosses up in arms but allow malingerers and timewasters to save their skin. Stealth settings, Yahoo claims, will allow users to hide their online status from their boss, for instance, but remain visible and so chattable to their friends. It all sounds like good clean fun, to be honest, they should call it skive and hide. One thing that struck me though…how many bosses use Yahoo Messenger anyway? Haven’t those in higher places been persuaded to run Skype these days?

What the !$%� do they know!?

What the Bleep makes its UK debut soon and gets slated by my old New Scientist mucker Marcus Chown.

One thing the movie claims (among many other ludicrous things) is that loving thoughts make for beautifully symmetric crystals whereas asymmetric and ugly crystals form from polluted water, or water that has been “subjected to” unhappy thoughts.

It’s obviously pseudoscientific claptrap, linking spirituality, consciousness, and quantum mechanics, but crystallographer Rick Bagshaw of the University of Toronto admits that “the more you swear at uncrystallized samples, the worse the outcome.” So, his negative empirical evidence almost backs up the film!

Of course, a deficit of crystallisation is the last thing a crystallographer needs, so Bagshaw has adopted “a more loving tone” for the sake of crystal growth.

I’m going to keep a check on Bagshaw’s publication frequency to see whether bigging up his crystals leads to bigger crystals.
