Frasassi Caves
The Frasassi Caves (Italian: ''Grotte di Frasassi'') are a karst cave system in the municipality of Genga, Italy, in the province of Ancona, Marche. They are among the most famous show caves in Italy. History The caves, discovered by a group of Ancona speleologists in 1971, are situated south of Genga, near the civil parish of San Vittore and the Genga-San Vittore railway station ( Rome-Ancona line). Rich in water, the cave system is particularly well endowed with stalactites and stalagmites. Near the entrance to the caves are two sanctuary-chapels: one is the 1029 '' Santuario di Santa Maria infra Saxa'' (Sanctuary of Holy Mary under the Rock) and the second is an 1828 Neoclassical architecture formal temple, known as Tempietto del Valadier. Chambers The Frasassi cave system includes a number of named chambers, including the following: * ''Grotta delle Nottole'', or "Cave of the Bats", named for the large colony of bats that lives within. * ''Grotta Grande del Vento ...

Stalagmite
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium c ...

Lesser Poland Voivodeship
Lesser Poland Voivodeship or Lesser Poland Province (in pl, województwo małopolskie ), also known as Małopolska, is a voivodeship (province), in southern Poland. It has an area of , and a population of 3,404,863 (2019). It was created on 1 January 1999 out of the former Kraków, Tarnów, Nowy Sącz and parts of Bielsko-Biała, Katowice, Kielce and Krosno Voivodeships, pursuant to the Polish local government reforms adopted in 1998. The province's name recalls the traditional name of a historic Polish region, Lesser Poland, or in Polish: Małopolska. Current Lesser Poland Voivodeship, however, covers only a small part of the broader ancient Małopolska region which, together with Greater Poland (''Wielkopolska'') and Silesia (''Śląsk''), formed the early medieval Polish state. Historic Lesser Poland is much larger than the current province. It stretches far north, to Radom, and Siedlce, also including such cities, as Stalowa Wola, Lublin, Kielce, Częstochowa, and S ...

Maurizio Montalbini
Maurizio Montalbini (4 September 1953 – 19 September 2009) was an Italian sociologist and caver who had lived in complete isolation in an underground chamber multiple times since 1986. Biography Montalbini was born at Senigallia. On December 14, 1986, he entered the Frasassi Caves of the Apennine Mountains, near Ancona. A video feed was set up to monitor him from the surface. He emerged on July 12, 1987, breaking the world record for complete isolation. An Ancona local named Stefania Follini heard of his exploits and decided to attempt it herself; NASA sponsored her stay in a cave in New Mexico. Her menstrual cycle stopped, and she began a sleep cycle of waking for 23 hours at a time and sleeping for 10 hours. Both Follini and Montalbini found that time passed quickly underground. Throughout 1993, Montalbini stayed in a cave in Pesaro. He again lost his sense of time, thinking it was only June when he was called to the surface in December. More precisely, he entered on ...

Chronobiology
Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. These cycles are known as biological rhythms. Chronobiology comes from the ancient Greek χρόνος (''chrónos'', meaning "time"), and biology, which pertains to the study, or science, of life. The related terms ''chronomics'' and ''chronome'' have been used in some cases to describe either the molecular mechanisms involved in chronobiological phenomena or the more quantitative aspects of chronobiology, particularly where comparison of cycles between organisms is required. Chronobiological studies include but are not limited to comparative anatomy, physiology, genetics, molecular biology and behavior of organisms related to their biological rhythms. Other aspects include epigenetics, development, reproduction, ecology and evolution. The subject Chronobiology studies variations of the ...
