This paper will describe the isolation and properties of a group new somatic hybrid cell lines obtained by crossing human diploid fibroblasts with an established mouse fibroblast line. These hybrids represent combination between species more remote than those previously described (see, however, discussion virusinduced heterokaryons). They are also first reported containing components possess which may be useful for certain types genetic investigations. Interspecific hybridizations involving...
Carbonatites are igneous rocks formed in the crust by fractional crystallization of carbonate-rich parental melts that mostly mantle derived. They dominantly consist carbonate minerals such as calcite, dolomite, and ankerite, well minor ...Read More

The abundance of FeTiO 3 and chromite precipitates in olivine the Alpe Arami peridotite massif, Switzerland, requires a much higher solubility for highly charged cations than is found mantle xenoliths from depths 250 kilometers. Three previously unknown crystal structures were identified that indicate originally exsolved phase was high-pressure perovskite polymorph ilmenite, implying minimum depth origin 300 These observations, coupled with unique lattice preferred orientation olivine,...
Samples of metastable Mg 2 GeO 4 olivine fail by faulting when loaded at temperatures where the incoherent nucleation and growth spinel (the stable phase) just becomes possible. At lower temperatures, transformation is inhibited, ductile strong, while higher happens very quickly, samples are weak. Microfaults that have been created slipped little contain only fine‐grained spinel. Those more a mixture larger, broken, fragments. A new type microstructure develops under nonhydrostatic stress...
Abstract The Central Orogenic Belt (COB) of China is a major continental collision zone that contains extensive outcrops deeply subducted and exhumed rocks at both the eastern western end belt. Here we report discovery microdiamonds from eclogites felsic gneisses in North Qinling central portion COB. This demonstrates country affinity shared ultra‐high‐pressure metamorphic (UHPM) event provides bridge connecting two previously recognized UHPM terranes, thereby establishing existence belt...
Cigarette smoking remains a significant health threat for smokers and nonsmokers alike. Secondhand smoke (SHS) is intrinsically more toxic than directly inhaled smoke. Recently, new has been discovered - Thirdhand (THS) the accumulation of SHS on surfaces that ages with time, becoming progressively toxic. THS potential to children, spouses workers in environments where or allowed. The goal this study investigate effects liver, lung, skin healing, behavior, using an animal model exposed under...
The deepest rocks known from within Earth are fragments of normal mantle (≈400 km) and metamorphosed sediments (≈350 km), both found exhumed in continental collision terranes. Here, we report a highly reduced deep environment at least 300 km, perhaps very much more, extracted chromite Tibetan ophiolite. sample consists, part, diamond, coesite-after-stishovite, the high-pressure form TiO 2 , native iron, nitrides with isotopic signature, associated SiC. This appears to be natural example...
Delineating Deep Faults Most large, damaging earthquakes initiate in Earth's crust where friction and brittle fracture control the release of energy. Strong can occur mantle too, but their rupture dynamics are difficult to determine because higher temperatures pressures play a more important role. Ye et al. (p. 1380 ) analyzed seismic P waves generated by 2013 M w 8.3 Sea Okhotsk earthquake—the largest deep earthquake recorded date—and its associated aftershocks. The ruptured along fault...

Observations by transmission electron microscopy show that lamellae of clinoenstatite are present in diopside grains the Alpe Arami garnet lherzolite Swiss Alps. The simplest interpretation orientation, crystallography, and microstructures phase relationships this system is originally exsolved as high-pressure C-centered form clinoenstatite. These results imply rocks were exhumed from a minimum depth 250 kilometers before or during continental collision.
Deep earthquakes have been a paradox since their discovery in the 1920s. The combined increase of pressure and temperature with depth precludes brittle failure or frictional sliding beyond few tens kilometers, yet occur continually subduction zones to approximately 700 km. expected healing effects growing amounts seismic experimental data suggest that at probably represent self-organized analogous to, but different from, failure. only high-pressure shearing instabilities identified by...
Geologists have "known" for many years that continental crust is buoyant and cannot be subducted very deep. Microdiamonds 10-80 microm in size discovered the 1980s within metamorphic rocks related to collisions clearly refute this statement, suggesting material of has been a minimum depth >150 km incorporated into mountain chains during tectonic exhumation. Over past decade, rapidly moving technological advancement made it possible examine these diamonds detail, learn they contain nanometric...
