Researchers in Germany have now been able to show that previously underrated immune cells, so-called mast cells, decide at a very early stage of an infection which way the defense has to go. They only produce the crucial messenger substance beta-interferon during a viral infection, not during a bacterial infection.

Visitors (who must be at least 16 years old) can hike in and out or ride one of the Molokai mules. The Molokai Mule Ride is the way most people visit the Kalaupapa settlement. Even if you hike, you must sign up for a tour. Itâs a 6.4-mile round trip trek, with 26 switchbacks and a 1,600-foot elevation drop. (Save some energy for the steep uphill return trip!) At the bottom of the trail, hikers join the mule riders for a guided walking and bus tour of Kalaupapa National Historic Park.
