Scientists find microbes in lava tube living in conditions like those on Mars The microbes were collected from a lava tube near Newberry Crater in Oregon’s Cascades Mountains, at an elevation of about 5,000 feet. They were within the ice on rocks some 100 feet inside the lava tube, in a low-oxygen, near-freezing environment.Conditions in the lava tube are not as harsh as on Mars,” Fisk said. “On Mars, temperatures rarely get to the freezing point, oxygen levels are lower and at the surface, liquid water is not present. But water is hypothesized to be present in the warmer subsurface of Mars.

Archaea These microbes are prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles in their cells. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this classification is outdated.ther aspects of archaeal biochemistry are unique, such as their reliance on ether lipids in their cell membranes. Archaea use more energy sources than eukaryotes: these range from organic compounds, such as sugars, to ammonia, metal ions or even hydrogen gas.

- Post 39. Archaebacteria are very similar to prokaryotes. But they differ from the cell wall and the cell membrane. In prokaryotic cell membrane a phospholipid bi layer is present. But in archaebacteria a single layer of phospholipid is available. That's a reason why they could live in very limited resource environments.

Archaea Archaea can be infected by double-stranded DNA viruses that are unrelated to any other form of virus and have a variety of unusual shapes, including bottles, hooked rods, or teardrops. These viruses have been studied in most detail in thermophilics, particularly the orders Sulfolobales and Thermoproteales.

Archaea Many archaea have been found living in extreme environments, for example at high pressures, salt concentrations or temperatures, and have been nicknamed extremophiles. Their cell wall differs in structure from that of bacteria and is thought to be more stable in extreme conditions, helping to explain why some archaea can live in many of the most hostile environments on Earth.

The Evolution of Prokaryotes: Archaebacteria and Eubacteria Archaea are divided into three categories based on the environments in which they live. 1  Thermophiles are heat-lovers and live in places such as deep sea thermal vents and hot springs. In Greek, the term 'therm' means 'heat,' such as in 'thermometer' and 'thermal underwear,' and 'philos' means 'lover.'.

Lava Lava flow during a rift eruption at Krafla, Iceland in 1984. Lava is the molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling.This molten rock is formed in the interior of some planets, including Earth, and some of their satellites.The source of the heat that melts the rock within the earth is geothermal energy.When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F).his molten rock is formed in the interior of some planets, including Earth, and some of their satellites.

- It was known before that Kilauea had small, shallow magma chambers , said Guoqing Lin, UM Rosenstiel School assistant professor of geology and geophysics and lead author of the study. This study is the first geophysical observation that large magma chambers exist in the deep oceanic crust below..The study also showed that the deep chamber is composed of magma mush, a mixture of 10-percent magma and 90-percent rock.The crustal magma reservoir below Kilauea is similar to those widely observed beneath volcanoes located at mid-ocean ridges.his is the first geophysical observation that large magma chambers exist in the deeper parts of the volcano system. Scientists analyzed the seismic waves that travel through the volcano to understand the internal structure of the volcanic system.

- The eruptions which produced the Uwekahuna Ash were much larger than those of 1790, but most of the deposits are buried by younger lava flows of Kilauea and Mauna Loa. The Pahala Ash formed from even larger explosive eruptions earlier in Kilauea's history.Two one-to-two-meter thick ashes underlie the Uwekahuna Ash but overlie the thickest prehistoric ash, a reddish sequence of ash up to 85 feet thick where it is exposed in the Hilina Pali.he current eruption along Kilauea's East Rift Zone continues with passive effusion of lava. The lava is transported underground to the coast along the western edge of the flow field, where it enters the ocean after cascading over an ancient sea cliff.

Introduction to the Archaea They may be extremely abundant in environments that are hostile to all other life forms. However, archaeans are not restricted to extreme environments; new research is showing that archaeans are also quite abundant in the plankton of the open sea. Much is still to be learned about these microbes, but it is clear that the Archaea is a remarkably diverse and successful clade of organisms.

Radiolaria Radiolaria are amoeboid protists which produce mineral skeletons. The skeletons, usually of silica (SiO 2), have a central capsule. This divides the cell into inner and outer portions, called endoplasm and ectoplasm.Radiolaria are found as zooplankton throughout the ocean, and their skeletal remains cover large portions of the ocean floor as radiolarian ooze.Radiolaria have existed since the beginning of the Palaeozoic era.They take their name from the radial symmetry of most species. They are valuable markers or diagnostic fossils, because they have a rapid turn-over of species. This helps to identify strata, and to correlate strata at different sites.adiolaria are found as zooplankton throughout the ocean, and their skeletal remains cover large portions of the ocean floor as radiolarian ooze.
