An Efe forest camp is usually dark and depending on the time of day, dripping from current or recent rain. The Efe live in dome shaped huts which may be more or less complete. A half dome might be a hut that was built quickly, or it might be a hut that was built more openly because it has been hot or it might be only a half dome to allow easier access in and out of the hut by children or individuals with injury or infirmity. A fully domed hut, with a small opening, keeps in more smoke (a fire is often kept in the hut) but it also keeps in the heat and keeps out the rain. So a rainy season hut may be a full-on dome with a small entrance way. Or, this kind of hut can be made when it has been cold, or when more privacy is needed, or, simply, when more time has been invested in making the hut.

A Hadron is a kind of particle, made of quarks. There are two kinds of hadrons, baryons (made out of three quarks) and mesons (made out of a quark and a quirky quark known as an antiquark).
The particle of interest is made up of an up quark, a strange quark, and a heavy bottom quark. I’ve known a few bluegrass bands that fit that description, but this particle is called the Xi-sub-b baryon.
The observation was made at the Collider Detector at Fermilab (CDF) .
The neutral Xi-sub-b belongs to the family of bottom baryons, which are about six times heavier than the proton and neutron because they all contain a heavy bottom quark. The particles are produced only in high-energy collisions, and are rare and very difficult to observe*.

Also, as a reminder, there is still time to make your opinion known regarding the proposed Sandhill Crane hunt in Kentucky: Last Gasp for Sandhill Cranes–Act Now!. And if you want to know why I never shot any cranes you can find out here: The first crane and the last crane
