Why I don’t go into the water…Reason #1,768

I could not be in the same ocean as this creature and not be gripped by paralyzing fear (not to mention paralyzing tentacles!). Behold, a great big jelly, the likes of which are not meant to be seen.

As the Discovery News reports, monster jellyfish like this are becoming more common as fish populations dwindle.

They say climate change could also cause jellyfish populations to grow. The team believes that for the first time, water conditions could lead to what they call a “jellyfish stable state,” in which jellyfish rule the oceans.

The combination of overfishing and high levels of nutrients in the water has been linked to jellyfish blooms. Nitrogen and phosphorous in run-off cause red phytoplankton blooms, which create low-oxygen dead zones where jellyfish survive, but fish can’t, researchers said.

Just great. We’re doomed.

Massive Bat Die-off in NJ? Maybe…and another fungus to blame!

The Star-Ledger reports that 95% of NJ bats died off this winter from a fungal infection known as “white-nose syndrome.” That sounds pretty damned scary, until you read the article and find that the headline was taken from a single reported hibernaculum (cool word meaning place where critters hibernate), the Hibernia Mine in Rockaway Township. Still, that doesn’t mean this isn’t serious. While Hibernia Mine might be an exceptional case, who knows (yet) how often this is repeating?

Screwed

Hibernia Mine doesn’t appear to be an active spelunking site, but you never know what desperate cavers might do in New Jersey. The Star-Ledger report fails to mention that the Fish and Wildlife Service has asked for a voluntary moratorium in the northeast to prevent the further spread of the disease.

So, like the frogs and bees, we have another fungal infection at the root of an animal die-off. With the bats, however, it seems decidedly linked to human activity, but there still could be a climate connection. (After all, why are people suddenly carrying fungi?) This press release from Cardiff University suggests climate change is causing fungi to grow more rapidly and “fruit” more frequently.

So, if you are doing math at home, is it:

warmer/wetter climate = more fungi + disease + accelerated decay (fungi hasten wood rot) = more CO2 = climate change

Yikes.

Keep Libel Laws out of Science

There’s a petition online in support of Simon Singh, the UK science writer being sued by the British Chiropractic Association for, essentially, using the word “bogus” in the same article as “chiropractic.” You can get the full scoop at Jack of Kent, a blog that has really nailed the issue from the start.

Here’s the article (originally posted on the Guardian’s site). And here’s an occurrence of the horrid word:

The British Chiropractic Association claims that their members can help treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying, even though there is not a jot of evidence. This organisation is the respectable face of the chiropractic profession and yet it happily promotes bogus treatments.

Is he wrong? I don’t think so. (In case you stumble across this, feel free to point me to the literature that shows chiro can treat children for the problems described above, Damien. Sorry, bro. I’ve always loved ya, man, but it seems implausible given the method of action.)

We don’t have the same libel laws in the US, of course, but chiropractic doesn’t really need the “protection” — few in the mainstream press ever call into question the effectiveness of chiropractic. Like many alternative medical practices, they tend to be accepted uncritically in the press. I think it might have something to do with the illusion of “balance” in reporting and the reluctance of the American press to tackle complicated issues surrounding science and medicine.

Man, these viral movie promotions are going too far…

Robot attacked Swedish factory worker – The Local.

The incident took place in June 2007 at a factory in Bålsta, north of Stockholm, when the industrial worker was trying to carry out maintenance on a defective machine generally used to lift heavy rocks. Thinking he had cut off the power supply, the man approached the robot with no sense of trepidation.

But the robot suddenly came to life and grabbed a tight hold of the victim’s head. The man succeeded in defending himself but not before suffering serious injuries.

“The man was very lucky. He broke four ribs and came close to losing his life,” said Leif Johansson.

Why I don’t go in the water…Reason #1,765

A 15 meter-long pliosaur with jaws that put T-Rex to shame. Sure, it died out 140-some million years ago, but try telling my imagination that.

Also scary, blue holes. Pathway straight to Cthulhu, if you ask me.

Black Sheep, THE best grossout horror comedy I’ve seen in years

This Saturday we were graced by the lovely Liz and her charming Frank. We provided the pizza (pi for pie day. Sicilian, of course, because pi are square. I’ll keep saying that until its funny.) and they provided the love, in the form of Black Sheep.

After seeing a trailer for it in front another Netflix rental, they immediately thought of us (gross out horror comedy, check! New Zealand, where Aly and I honeymooned, doublecheck!), and that’s why I love Liz. We sat Julia in the other room with pizza and Horton (she had just gotten a plastic lamb at the Elmwood Park zoo that afternoon, and that, plus guts, would have been too much — Responsible Dad!) and watched the hell out of that sucker. I was immediately taken back back 10 years to Liz and Aly’s apartment, watching horrible, horrible movies and being asked never, ever to go out and choose a movie on my own again.

But Black Sheep is everything I wished those other horror movies were. I give it: ♥ ♥ ♥ ∞, which I think means its good. It’s tough to say on this scale.

It was a fun film and you can see early Peter Jackson all over it, which isn’t a surprise considering that it takes place in New Zealand (I once described parts of the North Island as “rolling green hills covered in little white dots”) and because Weta Workshop did the effects (there was one scene where I swear they just replaced orcs with sheep). In fact, the first mutant lamb reminded me of the Sumatran rat monkey of Jackson’s Dead Alive (or Braindead, depending on what market you’re in, I guess).

I consider this movie an exemplar of the genre. Not as funny as, say, Shaun of the Dead, but a lot more disturbing. Fast-paced and scary in its own right, true to its own internal logic and funny without being slapstick-silly at every turn. It was well thought out and nicely put together, despite the low budget, full of nice, light touches and the rare treat of character development. In fact, I found the dialogue, in particular, to be smartly written. It is also a very bloody film, in the most meaty, visceral sense of the term.

As I said, you can see Weta Workshop’s hands all over this film. The special effects were great, especially the were-sheep and other sheepish monsters, but they weren’t above adding a few catapult-launched sheep for cheap, tension-cutting laughs. (Especially one flying lamb followed by a well-executed Wilhelm scream.)

It was also a beautiful movie, full of well-framed shots of the green, rich New Zealand countryside. (As I said, it was a very New Zealand movie — I also took smug delight in being able to explain what Aotearoa meant.) The attention the filmmakers paid to the landscape — not that I really know anything about cinematography — allowed the flick to move beyond the typical standards of the genre to something that was really quite well-crafted and watchable. I don’t know much about the director, Jonathan King, other than this is his first film, but I look forward to seeing his next one.

So, all and all, a proper pizza-and-beer flick, although you might want to hold the sausage.

Fruitflies like the wind, time flies like a banana…

Stop. Wait, reverse that. OK…

Another neat Eurekalert! feed story, one that offers tips for catching flies:

Caltech scientists discover mechanism for wind detection in fruit flies

Tiny, lightweight fruit flies need to know when it’s windy out so they can steady themselves and avoid being knocked off their feet or blown off course. But how do they figure out that it’s time to hunker down? According to a team led by California Institute of Technology (Caltech) scientists reporting in this week’s issue of the journal Nature, the flies have evolved a specialized population of neurons in their antennae that let them know not only when the wind is blowing, but also the direction from which it is coming.

The behavior of fruit flies in the face of a stiff breeze is remarkable in and of itself, notes David J. Anderson, the Roger W. Sperry Professor of Biology at Caltech, and a Howard Hughes Medical Institute (HHMI) Investigator. “We discovered that you can stop a fly dead in its tracks by blowing a gentle stream of air over it,” he explains, adding that the flies’ immobility is so complete, you could pick one up with a pair of chopsticks as long as a steady stream of wind was passing over the insect. Once the wind stops blowing, however, the flies immediately start walking around again.

Here’s a link to the video.

We can haz Make Day too?

While I’m thinking of The Franklin Institute, I’d like to reiterate my plea for a Maker Faire of our own. The Science Museum of Minnesota is having a little one this weekend.

More unsolicited science museum advice…

… actually it is advice from Paul Orselli’s ExhibiTricks blog. This might make a nice follow-up to my previous post on unsolicited advice for The Franklin, and it touches on similar themes…

A science museum, indeed every type of museum, is all about stories (human interaction) and stuff (interesting objects and materials.) Working with cool items or seeing interesting objects or devices while having an opportunity to interact with other people is what makes museums special, and incidentally different and more marketable, than on-line experiences or other types of for-profit entertainment centers.

At the end of the day, providing interesting opportunities for visitors and museum staff to interact with “stuff” (and each other) is a sure way for visitors to leave your museum NOT feeling stupid.

And that’s just a smart way to run a museum.

It reminds me of two rules I learned in grad school: 1) if your reader doesn’t understand something, you were probably unclear; and 2) you can please more than one type of reader at a time.

The first is obvious, to me at any rate. Anything that can be said, can be said simply enough to appeal to a person of reasonable intelligence. It really depends on being able to get a concept across without piling on confusing terminology, whether that concept is evolution or celestial physics. I don’t believe you can get someone to completely grok quantum physics in five seconds, but they might get the gist that regular old physics doesn’t work so well in explaining how things atom-sized and smaller behave, which is where quantum mechanics comes in. People tend to understand things when you break them down into digestible chunks (or quanta — ha!) of information.

The second, I think, applies to science museums, in particular. I’m not an exhibit designer — and I know nothing about museum pedagogy — but I would think a good exhibit is like a an old Warner Bros. cartoon: the kids don’t get the dirtier jokes, but the adults do. (Good example here in “An Itch In Time,” at the seven minute mark below. It went over my head as kid.) Likewise, I can see where it would be necessary to design an exhibit — to create an “experience” — that appeals kids, adults and science geeks alike. I think you would do that by engaging people in the process. Like Paul, I was impressed with how interactive the recent Star Wars exhibit was. Even my three year-old got into creating LEGO landspeeders.
