Gah! How ticks dig in

Following up on our previous post, NPR has an article, with creepy video, explaining possibly way more than you want to know about how ticks grab on and dig in. It also has some useful advice on removing ticks . . .

Spring is here. Unfortunately for hikers and picnickers enjoying the warmer weather, the new season is prime time for ticks, which can transmit bacteria that cause Lyme disease.

How they latch on — and stay on — is a feat of engineering that scientists have been piecing together. Once you know how a tick’s mouth works, you understand why it’s impossible to simply flick a tick.

The key to their success is a menacing mouth covered in hooks that they use to get under the surface of our skin and attach themselves for several days while they fatten up on our blood.

This was an interesting find. “99% Invisible” is a professionally produced podcast “about all the thought that goes into the things we don’t think about.” Recently, they focused on the U.S. national trail network.

This a two-part article. Links to both segments are below . . .

The U.S. National Trails System‘s 30 Scenic and Historic routes alone span over 50,000 miles, longer than the entire Interstate Highway System. Extending across all 50 states, the National Recreation Trails network contains over 200,000 additional miles of public pathways. A person could walk these trails continuously for years and still experience only a fraction of the total system.

Sustaining public trails throughout the nation is a herculean task coordinated by various federal agencies (including the National Park Service, Bureau of Land Management, USDA Forest Service, U.S. Fish & Wildlife Service, and U.S. Army Corps of Engineers) as well as state-level organizations, like the California Conservation Corps (or: CCC). In turn, these agencies rely on a huge number of paid and volunteer workers to create and maintain both federal and state trails nationwide.
