The Frisian Islands are barrier islands off the coast of the Netherlands. Between these islands and the mainland, there is an area called the Wadden Sea. This sea is only wet in some places, at some times. Instead of being a proper body of water, it's speckled with shallow pools, wetlands, mud flats that flood and dry up depending on storms and changing tides.
That geography makes the Frisian Islands, including the island of Texel, a great place to go beachcombing. During high tides and storms, water from the North Sea flows into the Wadden Sea through inlets. Not all of this water flows back out again, some evaporates. And water isn't the only thing in the North Sea. Wander the mud flats after the tide goes back out and you'll find all manner of random things washed up on Texel's shores—from buckets and signs, to bottles stuffed with anonymous letters.
On a more practical level, current patterns in the North Sea push whatever is in the water towards Texel. That means when a container ship loses something like a box full of luxury coats, the beaches of Texel are a great place to find it again. All that flotsam and jetsam (both the useful and the whimsical) helped create a culture of beachcombing on Texel. For generations, people went down to the shore and finders-keepers was the name of the game.
You can watch a new 14-minute documentary on Texel beachcombers and the goodies they've found. It's called Flotsam & Jetsam and it's available on Vimeo and it's really interesting—a great example of how the realities of nature and science can shape the way culture develops.

A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
