Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.
One of the primordial nuclides is tantalum-180m, which is predicted to have a half-life in excess of 10 15 years, but has never been observed to decay. The even-longer half-life of 2.2 × 10 24 years of tellurium-128 was measured by a unique method of detecting its radiogenic daughter xenon-128 and is the longest known experimentally measured ...

Coughing is a physiologic way to rid one of some of the congestion, says Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security. Controlled cough is a mucus-clearing ...
In the Ascomycota this attribute is most often found in the ascogenous hyphae and ascocarp while the bulk of the mycelium remains monokaryotic. In the Basidiomycota this is the dominant phase, with most Basidiomycota monokaryons weakly growing and short-lived.
A preliminary investigation by homicide detectives found Mina lived at the location with her boyfriend, Sanchez, and the victim's two children: an 8-month-old infant and a 2-year-old boy.
