Casimir Pulaski Day is a local holiday officially observed in Illinois, on the first Monday of March in memory of Casimir Pulaski, a Revolutionary War cavalry officer born in Poland as Kazimierz Pułaski. He is praised for his contributions to the U.S. military in the American Revolution and known as "the father of the American cavalry".
The St. Peter Sandstone is an Ordovician geological formation. It belongs to the Chazyan stage of the Champlainian series in North American regional stratigraphy, equivalent to the late Darriwilian global stage. This sandstone originated as a sheet of sand in clear, shallow water near the shore of a Paleozoic sea and consists of fine-to-medium-size, well-rounded quartz grains with frosted surfaces. The extent of the formation spans north–south from Minnesota to Arkansas and east–west from Illinois into Nebraska and South Dakota. The formation was named by Owen (1847) after the Minnesota River, then known as the St. Peter River. The type locality is at the confluence of the Mississippi and Minnesota Rivers near Fort Snelling, Minnesota. In eastern Missouri the stone consists of quartz sand that is 99.44% silica.
Lincoln's Birthday is a legal, public holiday in some U.S. states, observed on the anniversary of Abraham Lincoln's birth on February 12, 1809 in Hodgenville, Kentucky. Connecticut, Illinois, Indiana, Ohio, Texas, California, Missouri, and New York observe the holiday.
The smoky shrew is a medium-sized North American shrew found in eastern Canada and the northeastern United States and extends further south along the Appalachian Mountains.
The Arapaho National Wildlife Refuge is a United States National Wildlife Refuge located in north central Colorado. It is one of over 560 national wildlife refuges which manages and protects natural resources for future generations. The refuge is located in North Park in central Jackson County south of the town of Walden. The refuge was established in 1967 to furnish waterfowl with a suitable place to nest and rear their young. It was created in part to offset losses of nesting habitat in the prairie wetland region of the Midwest. It is located in the valley of the Illinois River, a tributary of the North Platte River. It is administered by the United States Fish and Wildlife Service.
The Zempoaltépec vole is a species of rodent in the family Cricetidae. The name Microtus is from the Greek word mikros meaning small and otus meaning ear. The name umbrosus could be from the Latin umbros meaning shady. It is rather large and has a long tail when compared with other voles. Its pelage is long and soft. In the upper parts, the hair is uniformly dusky with brown tips and the lower parts a dark grey thinly washed with a reddish yellow color. It is found only in Mexico, in a semi-isolated mountain range southeast of the Cajones River in Mixes district, in Oaxaca.
Porphyrellus is a genus of fungi of the family Boletaceae.
Herbert Sander Gutowsky was an American chemist who was a Professor of Chemistry at the University of Illinois at Urbana-Champaign. Gutowsky was the first to apply nuclear magnetic resonance (NMR) methods to the field of chemistry. He used nuclear magnetic resonance spectroscopy to determine the structure of molecules. His pioneering work developed experimental control of NMR as a scientific instrument, connected experimental observations with theoretical models, and made NMR one of the most effective analytical tools for analysis of molecular structure and dynamics in liquids, solids, and gases, used in chemical and medical research, His work was relevant to the solving of problems in chemistry, biochemistry, and materials science, and has influenced many of the subfields of more recent NMR spectroscopy.
Urticicola umbrosus is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Hygromiidae, the hairy snails and their allies.
A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.
Apateon is an extinct genus of temnospondyl amphibian within the family Branchiosauridae.
Plasmodium traguli is a parasite of the genus Plasmodium subgenus Vinckeia. As in all Plasmodium species, P. traguli has both vertebrate and insect hosts. This particular species infects mouse deer in Southeast Asia.
Pseudometapterus is a little-known genus of thread-legged bug in the subfamily Emesinae. Members of the genus occur in North America and usually have wings that are extremely small or absent entirely, though a winged form of P. umbrosus is known from Southern Illinois.
Malcolm X Day is an American holiday in honor of Malcolm X that is celebrated on either May 19 or the third Friday of May. The commemoration of the civil rights leader has been proposed as an official state holiday in the U.S. state of Illinois in 2015 and Missouri as recent as 2019. As of present, only the city of Berkeley, California observes the holiday with city offices and schools closed.
