The dangers of Escherichia coli

New York Times: Trail of E. Coli Shows Flaws in Inspection of Ground Beef. (Link via dangerousmeta!)

Just reading the description of how hamburger meat is manufactured makes me sick to my stomach. And that’s just a metaphor; for Stephanie Smith, the E. coli infection with a very dangerous strain called O157:H7 was life-threatening, and she will likely be in a wheelchair for the rest of her life.

The rules for processing meat might be a little tighter in the European Union or Germany, but the danger of contamination still remains high if meat from several sources is combined for grinding. The companies combine sources for hamburger in order to save money, but personally I don’t mind paying a bit more for safer meat.

We are lucky to have a good butcher in town: Each week they put up a notice stating where the animals they slaughtered were bred (all farms in a 30 mile radius), and if you want to buy ground meat, they always prepare it fresh and right before your eyes, and they use only meat, no fillers. It might be a little more expensive than pre-packaged groud meat from the supermarket, but it’s safer and tastes better.

Update: There’s a MetaFilter thread now as well: Welcome to the jungle.

Funny, but it’s still rock ‘n roll to me

A couple of weeks ago I had to get an MRI scan of my head because of my frequent headaches. I wasn’t so much worried about the results as curious about the procedure because I’ve studied MRI and other medical imaging technology at university in theory and was interested in seeing an MRI scanner in real life. As it turns out, I was right, and everything is perfectly fine inside my head (I can now prove that I’ve got a brain!), and the scan was an interesting experience.

I was told beforehand that it was going to be very, very loud inside the scanner, so I was prepared for it to be very, very loud. Fortunately, I was given ear muffs, and the noise wasn’t really that bad. I had heard it being described as loud knocking or banging sounds, but found that it didn’t sound like knocking at all. It rather sounded like an electronic beat or an electronic bass guitar and reminded me of the beginning of this song by Bily Joel, which is among my favourites since I played it in our highschool Big Band. (In that version, I actually played the bass part on the piano, so I know it very well.)

All of this is just a long-winded introduction to this link: What does an MRI scanner sound like? which I found over at LaLaGirl today. You can listen to MRI sounds there without actually having to go into a scanner. Just imagine the sounds to be quite a bit louder and all around you.

P.S.: I had tickets to a Billy Joel and Elton John concert when they did their “Face 2 Face” tour in Germany. Unfortunately, Billy Joel had an inflammation of the vocal chords and was unable to perform, so Elton did the show all by himself. Since then I’ve been hoping that they will be doing another concert together somewhere in Germany. I hear there’s another tour scheduled for 2009, so I’m keeping my fingers crossed.

P.P.S.: auf Deutsch gibt es natürlich auch eine Seite bei Wikipedia zur Magnetresonanztomographie bzw. Kernspintomographie: MRT.

Chernobyl

It’s been a little over 21 years now since the nuclear power plant in Chernobyl blew up. I wrote about it on the 20th anniversary and a few years earlier, but the MetaFilter thread Chernobyl – 20 years later has some new (at least to me) links on the topic.

My Journey to Chernobyl: 20 Years After the Disaster is an article with photos by Mark Resnicoff, who traveled to the contamination zone in June 2006. There also is a discussion about his essay.

Chernobyl Legacy by Paul Fusco:

On April 26th, 1986, Chernobyl’s Reactor No. 4 unleashed a thoroughly modern plague that emptied cities, condemned entire regions, and seeped invisibly into the bodies of those exposed to its destructive presence.

Photographer Paul Fusco faces the dark legacy of Chernobyl, focusing on the horrifying human consequences of the event that is now 20 years in the past. Fusco’s work forces us to remember an important nightmare that we would forget at the peril of our morality and our future.

It takes a while for the site to load, but it’s worth the wait. At least look at and listen to “Chernobyl legacy” from the menu.

Karol Lasia has a collection of black-and-white photos from the area. Lasia was born in 1986 and traveled to Chernobyl and Pripyat in the summer of 2006.

Diese Woche in der Zeit

Einen Tag vor den Herbstferien komme ich mal wieder dazu, nicht nur die Zeit am Tag des Erscheinens zu lesen, sondern auch auf ein paar lesenswerte Artikel aufmerksam zu machen:

Wirtschaft: An die Kette gelegt. “Die Buchpreisbindung sollte kleinen Händlern und Verlegern das Überleben sichern. Doch inzwischen fördert sie die Konzentration in der Branche.” Von Jens Uehlecke.

Aus der Reihe Patient Kind: Fataler Irrtum in der Abwehr. “Neue Therapien sollen Allergien bekämpfen. Die Ärzte träumen von einer wirksamen Prävention.” Von Ute Eberle.

»Sie ist eine Lady« “Wie ist es, wenn die eigene Mutter wieder zu Hause einzieht? Ingrid Noll kennt sich damit aus – sie pflegt ihre 105 Jahre alte Mutter. Ein Gespräch mit der Schriftstellerin.”

Reisen: Gut gepolstert zu den Göttern. “Komfortabler kommt man nicht von Mumbai nach Goa. Der Luxuszug »Deccan Odyssey« lässt Indiens Wunder wie einen langen Film vorüberziehen. Draußen ist es 43 Grad heiß, drinnen reicht Pravakar Schnittchen.” Von Karin Ceballos Betancur.

Schule: Die Mathe-Revolution. “»Sinus« verändert den Mathematikunterricht an deutschen Schulen. Ein Beispiel aus Brandenburg zeigt, wie.” Von Julian Hans.

Chernobyl – Tschernobyl

Twenty years ago today, a nuclear reactor in Chernobyl, USSR (now Ukraine), exploded and released 100 times the radiation of the Hiroshima and Nagasaki atomic bombs (source). I was ten years old at the time, and I remember that when the news about the atomic catastrophe finally reached Germany, we were not allowed to play outside in the sand, on the playground, or in the rain. Of course I was too young to understand what had happened, but I was scared.

Twenty years later, I do understand how atomic plants work and how the accident in Chernobyl happened, but it’s still hard to grasp the sheer enormity of the consequences.

Pripyat is a town close to Chernobyl which housed many of the workers at the atomic plant. It has been abandoned after the accident. Pripyat and the 30k zone is David McMillan’s colletion of photos he took in Pripyat in 1994 and 2004.

You may remember Elena Filatova who gained fame about two years ago for publishing photos from her trip to Pripyat on her website. She has also published a short film called Ghost Town (54 MB quicktime film) which has some footage from the evacuation of Pripyat twenty years ago.

Spiegel online has an article on Chernobyl in its English section: Chernobyl’s Aftermath: The Pompeii of the Nuclear Age, including a photo gallery on the aftermath of the disaster.

Twenty years are not a long time when it comes to some radioactive nuclides: for example, uranium 238 has a half life of 4.5 billion years. Two of the radionuclides emitted in Chernobyl are caesium 137 with a half life of about 30 years and iodine 131 with a half life of eight days (Halbwertszeiten). The latter is accumulated in the thyroid of humans, which can lead to cancer. The Chernobyl Children’s Project International tries to help the people of Chernobyl and the surrounding towns in many ways.

Nuclear nightmares is a collection of photographs by Robert Knoth (reporting by Antoinette de Jong). The photos show people who live around Chernobyl, but be aware that some of the pictures are really disturbing. (Link via MetaFilter.)

Das Physik-Journal widmet dem Tschernobyl-Unglück einen großen Teil der aktuellen Ausgabe.

Die Zeit: Atomkraft: Es gibt ein Leben nach Tschernobyl. “Zuerst kehrten die Alten zurück, denen Heimat mehr bedeutete als Radioaktivität. Zwanzig Jahre nach der Reaktorkatastrophe haben sich die Menschen der Region mit der Strahlung trotzig arrangiert”. Von Hans Schuh.
