Sweden: Now Featuring…Spring!

I hear reports that dandelions have now been spotted at the space campus here in Kiruna. I haven’t personally seen them, but I can share a photograph of another flower, spotted after dinner last night:

This is a kind of flower that I want to call a catkin. I don’t know if that’s correct. But that’s what I want to call it, which I think gives it at least a 50% chance of being right. I’m also going to guess that the plant is some kind of willow. Anyway, isn’t it pretty? Several of these flowers had insects crawling around on them. Pollination in action!

Spotted in Norway: Spring

A few weeks ago I got excited about seeing flies; this weekend, it was dandelions. That’s how you know it’s been a long winter. This is in a park in Narvik, in northern Norway. Narvik is coastal–warm Atlantic currents keep its harbor ice-free in winter–and spring apparently hit there earlier than in Kiruna.

It’s just a little dandelion, poking its way up through the grass, but isn’t it pretty? Dandelions are composites, a kind of plant that has dozens or hundreds of flowers all packed together in a flower-like shape. Each of those yellow petals and curly reproductive bits is attached to a tiny flower, anchored into the base that you’ve seen–it’s the litle plug left behind when the tiny seed-parachutes blow away. Asters, daisies, and sunflowers are all composites. I think they’re my favorite plant family.

By the way, dandelions are an introduced weed in North America, but they’re native to Europe and Asia. Which doesn’t mean the person in charge of this lawn necessarily wants them there. But still, they’re less foreign here in Narvik than in Maryland or Montana.

Whoa, That’s a Wolverine

I knew of wolverines as a North American animal, and an animal of northern places, but only because I knew they were the mascot of a university somewhere in the northern half of the U.S. Well, now I know they are also European.

Rawr.

I encountered this wolverine yesterday in Narvik, a town in northern Norway. In the train station, in fact. What is a stuffed wolverine doing in a train station waiting room? A plaque says it was hit by a train on October 10, 1997. At least the little guy’s body didn’t go to waste.

There are a few passenger trains to Narvik every day, but most of the trains on the line carry iron ore. That’s what the train line was built for. Kiruna, where I’m currently living, sits on top of a very productive iron mine. In the early 1900s, a mining company built the train line from Kiruna to Narvik’s large, ice-free harbor. In fact, there’s no rail connection from Narvik to the rest of Norway; it’s a dead end on the Swedish rail network.

Wolverines are the largest land-dwelling members of the weasel family. (Some otters are bigger.) They are tough little carnivores that live in mountains and the way north, with strong jaws that help them eat frozen meat and big paws that help them get around on snow. As of the mid-90s there were about 150 in Norway and about 250 in Sweden. Trains are not a major threat. Their range has shrunk a lot over the years, probably mostly because of deforestation and development. According to the International Union for the Conservation of Nature, they’re doing ok worldwide, but the European wolverines are in more trouble. The IUCN has details.

Here’s a bonus scenic shot, taken from the train as it descended from the Swedish border to Narvik.

Those iron pellets get a mighty nice view on their way to sea.

Snow Around Trees

Up here above the Arctic Circle in Sweden, spring has been slow to come. I suppose technically it arrived on March 20, the same as everywhere else in the Northern Hemisphere, but we’ve got a while to wait until nature catches up. There’s still a lot of snow on the ground. In fact, it snowed last night. I can see plenty of green out the window, but it’s evergreen. Grass is emerging from under the snow along the roads–but it’s all brown.

I took this picture yesterday evening.

The patches around the trees were the first to emerge from under the snow. It started a few weeks ago, with trees on a west-facing slope that got lots of nice sunlight in the afternoon. This tree is in the woods, with less direct sun. My best guess from asking Dr. Google is that snow melts around trees first because the bark absorbs heat from the sun.

Greater Wax Moth Ear News

No, not greater moth earwax news. News about the ears of the greater wax moth. It’s a moth that causes problems for apiculturalists around the world, by crawling into beehives and laying eggs so the larvae can hatch and fatten up on the delicious honeycomb.

The piece I wrote yesterday had nothing to do with their peskiness. It was about their hearing, which goes to very high pitches. They hear way up into ultrasound range. Ultrasound is defined as anything above the range of human hearing, which tops out around 20-23 kHz. Dogs make it to about 45, mice get up to 90 or so, and these moths get to 300 kHz. That’s high. (The ultrasound machines used to look inside your body are much higher-pitched, in the megahertz range.) Find out more at the Science website.

Love my Livescribe Pen

I just realized I’d never pointed out a blog post I wrote months ago for the website of the Science Writers’ Handbook. I’ve raved on many occasions about my Livescribe pen, so the folks who are running the blog asked me if I’d write about it. See my writing–and a video of the pen in action–on the Pitch Publish Prosper website.

The book is out now and we’ve been hearing lots of nice things about it. I don’t have a copy myself, because I’m way too cheap to pay international shipping to get it sent to me here in Sweden (and if I did get it sent here, I’d just have to lug the darn thing home again). But I look forward to reading it when I’m back in the U.S.!

Bug on my Snow

You know you’re ready to be done with winter when you get excited about seeing flies.

This bug was on the snow in front of the Swedish Institute for Space Physics in Kiruna, Sweden. It’s a fly. A big, fuzzy one. That is as far as I am willing to go with insect identification.

These little guys really were the first sign of spring. First I saw one in an office. A few days later, I found one banging itself against a window in my apartment. I opened the casement and wafted it out. It was in the 30s, but maybe Swedish flies like the cold. This one seems to.

See other bugs in the Bug on my Window series.

How to Find Out What Dolphins Eat

How do you find out what animals eat? Well, one way is to collect their poop. What goes in must come out, in one form or another. Before the rise of DNA techniques, the only way to analyze feces was by digging through it for recognizable bits of prey. Now all you need is for some DNA to make it through the digestive system and you can amplify it, compare it to a gene library, and figure out what species your animal of interest has been munching on.

Yesterday for ScienceNOW I wrote about a study on dolphin diet. The researchers compared DNA data from poop to data on the stomach contents of dead dolphins that were picked up through the Florida Marine Mammal Stranding Network. Find out what they learned.

Museum Tourist: Cité de l’Espace

Toulouse is a lovely city in Southwestern France, known for its pink-tinged bricks, violets, and art museums. But it’s also a major center for air and space business and science. Airbus has its headquarters there. It was space science that brought me to Toulouse; my boyfriend was working with some space science researchers for a month. And one of Toulouse’s major tourist attractions is Cité de l’Espace [http://www.cite-espace.com/en], a theme park and science museum about space.

Cité de l’Espace isn’t about looking at space-related artifacts, and there aren’t many. It’s about having fun and learning scientific concepts. Most of my pictures are of one of us doing something, like the track that lets you bounce and soar as if you were in the low gravity in the moon.

Which was fun, and worth the half-hour wait in line.

They do have some actual stuff, though, like a section of a Soyuz spacecraft. The one they have is a training module.

You’ve probably heard of Soyuz. It was designed in the space-race days of the 1960s. Here’s the crazy thing, though–while the U.S. moved on from the Apollo designs, the Soviet Union didn’t.

The U.S. developed the Space Shuttle and the Soviets, and later the Russians, kept on using the Soyuz. The Shuttle has been retired–so when astronauts go to the International Space Station, they go in a Soyuz. The instruments have been updated since the 60s, but basically astronauts are getting to space today like some of the first cosmonauts did. It’s old, but it’s cheap and it works.

If you go to Cité de l’Espace, you can climb into a Soyuz, too. We happened to be walking by at the beginning of the two-hour window when it was open, so we were near the front of the line. And it was pretty cool. You take off your shoes, climb a few stairs, then lower yourself in through a hatch. It looks like it would be awfully cramped with three full-grown adults in there, but once you get inside it doesn’t seem so bad.

Once the astronauts are in space, there’s a second module they can go into, although I think it’s not particularly large, either. I imagine after two days together you’re ready for the comparative roominess of the International Space Station. Actually, I just learned, they’ve recently shown that it’s possible to get to the ISS in six hours, but it means maneuvering both the Soyuz and the space station very, very carefully, and they may just stick with the two-day plan in the future.

However you get up there, it only takes a few hours for a Soyuz to leave the station, enter the atmosphere, open its parachute, and go thunk on the ground somewhere in Central Asia.

Outside there are full-sized replicas of a Mir space station and an Ariane 5 rocket, the European Space Agency’s new way to get satellites into space.

Fun fact: The Ariana 5 is launched from French Guiana, along the northern edge of South America. When you launch something into space, you want a big stretch of open water to the east, to catch the bits of rockets that are meant to fall off. (And the ones that aren’t.) You also want to be near the equator, for reasons I understand less well. Note that these are two things the Guiana Space Centre has in common with Cape Canaveral.

The entrance fee to Cité de l’Espace is high, more than $25 when we were there, but you don’t have to pay extra for any of the attractions, like the aforementioned moonwalk, the IMAX, or the planetarium shows. And you learn a lot about space.

In Other Book News….

I wrote a Friday Snapshot for the book blog. It’s about a Friday I spent in Switzerland about a month ago – I wrote it then and they held it until there was a hole in the schedule.

I actually spent yesterday in Longyearbyen, on the Norwegian island of Svalbard. I’m up here at 78 degrees north for a story. It’s cold! And scenic! And wonderful! More details to follow when the story is published, later this year.

This sign on the way out of town tells you that the warning applies everywhere in Svalbard.
