Mitja Brodar Mitja (Demetrij) Brodar (1921 – 16 February 2012) was a Slovenian paleontologist. He was a son of Srečko Brodar, a pioneer of the study of the Paleolithic period in Slovenia. In the sixties and seventies of the 20th century Brodar, together with France Osole, was leading the Paleolithic research in Slovenia. He was born in 1921 in Celje where his father was at the time teaching science at the Grammar school in Celje. During Italian occupation of Ljubljana in WW2 he joined the anti-Nazi resistance movement, was captured in 1942 and sent to the Italian concentration camps in Rab, Reka [Fiume] and in Visco. Brodar studied civil engineering at the University of Ljubljana, at the wish of his father (graduated in 1949) | Natural_sciences | https://en.wikipedia.org/wiki?curid=36774535 | Mitja Brodar |
Mitja Brodar Later he also studied geology and paleontology with graduation in 1953. Since 1952 he was a member of Ljubljana Cave Exploration Society (DZRJL). Between 1954 and 1956 and in 1960 he was excavating the cave Mokriška jama. He received PhD in 1959 with a thesis on those excavations. Betal Rock Shelter () is another site he was excavating. He helped establish and was during the 1970s president of the Slovene archaeological association. Together with his father he wrote a book on Potok Cave () excavations. According to Brodar, the Divje Babe flute is a product of Cro-Magnon, modern human, and not Neanderthal. | Natural_sciences | https://en.wikipedia.org/wiki?curid=36774535 | Mitja Brodar |
Philipp Maximilian Opiz Philipp (Filip) Maximilian Opiz (5 June 1787 in Čáslav – 20 May 1858 in Prague) was a Czech-German forester and botanist. Beginning in 1805 he served as a cameral-beamter in his hometown of Čáslav, later working in Pardubice (from 1808) and Prague (from 1814). In 1831 he became a "Forstamtsconcipist" (forestry official). He was the taxonomic authority of numerous plant species, and the creator of many sets of exsiccatae. In 1830 Carl Borivoj Presl named the genus "Opizia" in his honor. | Natural_sciences | https://en.wikipedia.org/wiki?curid=36774855 | Philipp Maximilian Opiz |
Autochthon (geology) An autochthon in structural geology is a large block or mass of rock which is in the place of its original formation relative to its basement or foundation rock. It can be described as rooted to its basement rock as opposed to an allochthonous block or nappe which has been relocated from its site of formation. While an autochthon may have experienced some minor shifting, an allochthonous block will have moved at least a few kilometres. If an overlying allochthon has an opening or hole which exposes the underlying autochthonous material, the hole is called a window (or Fenster). Authochthous sediment is sediment found at or very close to its site of deposition. The etymology of the term is from Greek: 'autos' means self, and 'chthon' means earth. | Natural_sciences | https://en.wikipedia.org/wiki?curid=36795154 | Autochthon (geology) |

Vaupés Arch The is a hydrographic feature in the geology of Colombia. The forms the major drainage divide in the southern extent of the "llanos" region of eastern Colombia and the western slopes of the Guiana Shield in Venezuela. The is the result of an episode of tectonic uplift that occurred approximately 8 to 10 Ma. The rise of the divided the basin of the Amazon from the headwaters of the Orinoco for the first time. Much of the Arch is now buried under thick sediments washed from the Andes. Shifting meanders of the area's numerous waterways have spread these sediments evenly over the flat alluvial plain, which has very little relief | Natural_sciences | https://en.wikipedia.org/wiki?curid=36817758 | Vaupés Arch |

Moaning sandbar Moaning sandbars are harbor shoals that are known for tidal noises. Water flowing over a sandbar, typically around low tide, can coincide with both low, sustained noises and turbulence dangerous for smaller boats. In English-speaking culture, phrases such as "moaning of the bar" connect these sounds with mortal danger. In the mid-19th-century, the phrase "the harbor bar be moaning" in the poem and lyric "Three Fishers" connected working-class suffering to the noises. Later in that century, Alfred Lord Tennyson wrote "Crossing the Bar", coupling "May there be no moaning of the bar" with images of life's end, and then designated it as essentially his own requiem. This came soon after his making a trying sea journey | Natural_sciences | https://en.wikipedia.org/wiki?curid=36828359 | Moaning sandbar |

3D cell culturing by magnetic levitation 3D cell culture by the magnetic levitation method (MLM) is the application of growing 3D tissue by inducing cells treated with magnetic nanoparticle assemblies in spatially varying magnetic fields using neodymium magnetic drivers and promoting cell to cell interactions by levitating the cells up to the air/liquid interface of a standard petri dish. The magnetic nanoparticle assemblies consist of magnetic iron oxide nanoparticles, gold nanoparticles, and the polymer polylysine. 3D cell culturing is scalable, with the capability for culturing 500 cells to millions of cells or from single dish to high-throughput low volume systems | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation Once magnetized cultures are generated, they can also be used as the building block material, or the "ink", for the magnetic 3D bioprinting process. Standard monolayer cell culturing on tissue culture plastic has notably improved our understanding of basic cell biology, but it does not replicate the complex 3D architecture of in vivo tissue, and it can significantly modify cell properties. This often compromises experiments in basic life science, leads to misleading drug-screening results on efficacy and toxicity, and produces cells that may lack the characteristics needed for developing tissue regeneration therapies | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation The future of cell culturing for fundamental studies and biomedical applications lies in the creation of multicellular structure and organization in three-dimensions. Many schemes for 3D culturing are being developed or marketed, such as bio-reactors or protein-based gel environments. A 3D cell culturing system known as the Bio-Assembler™ uses biocompatible polymer-based reagents to deliver magnetic nanoparticles to individual cells so that an applied magnetic driver can levitate cells off the bottom of the cell culture dish and rapidly bring cells together near the air-liquid interface. This initiates cell-cell interactions in the absence of any artificial surface or matrix | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation Magnetic fields are designed to rapidly form 3D multicellular structures in as little as a few hours, including expression of extracellular matrix proteins. The morphology, protein expression, and response to exogenous agents of resulting tissue show great similarity to in vivo results. method (MLM) was developed from collaboration between scientists at Rice University and University of Texas MD Anderson Cancer Center in 2008. Since then, this technology has been licensed and commercialized by Nano3D Biosciences. Above is a picture showing 3D cell culturing through magnetic levitation with the Bio-Assembler cell culturing system | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation (A) A magnetic iron oxide nanoparticle assembly known as Nanoshuttle is added and dispersed over cells and the mixture is incubated. (B) After incubation with Nanoshuttle, cells are detached and transferred to a petri dish. (C) A magnetic drive is then placed on top of a petri dish top. (D) The magnetic field causes cells to rise to the air–medium interface. (E) Human umbilical vein endothelial cells (HUVEC) levitated for 60 minutes (left images) and 4 hours (right images) (Scale bar, 50 μm). The onset of cell-cell interaction takes place as soon as cells levitate, and 3D structures start to form. At 1 hour, the cells are still relatively dispersed, but they are already showing some signs of stretching | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation Formation of 3D structures is visible after 4 hours of levitation (arrows). Protein expression in levitated cultures shows striking similarity to in vivo patterns. N-cadherin expression in levitated human glioblastoma cells was identical to the expression seen in human tumor xenografts grown in immunodeficient mice, while standard 2D culture showed much weaker expression that did not match xenograft distribution as shown in the picture below. The transmembrane protein N-cadherin is often used as an indicator of in-vivo-like tissue assembly in 3D culturing | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |

(middle), and cells cultured on a glass slide cover slip (2D, right). The 2D system shows N-cadherin in the cytoplasm and nucleus and notably absent from the membrane, while in the levitated culture and mouse, N-cadherin is clearly concentrated in the membrane, and also present in cytoplasm and cell junctions. One of the challenges in generating in vivo like cultures or tissue in vitro is the difficulty in co-culturing different cell types | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation Because of the ability of to bring cells together, co-culturing different cell types is possible. Co-culturing of different cell types can be achieved at the onset of levitation, by mixing different cell types in before levitation or by magnetically guiding 3D cultures in an invasion assay format. The unique ability to manipulate cells and shape tissue magnetically offers new possibilities for controlled co-culturing and invasion assays. Co-culturing in a realistic tissue architecture is critical for accurately modeling in vivo conditions, such as for increasing the accuracy of cellular assays as shown in the figure below. Shown in the picture above is an invasion assay of magnetically levitated multicellular spheroids | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |

Invasion of GBM into NHA in 3D culture provides a powerful new assay for basic cancer biology and drug screening (right, 12h to 252h). By facilitating assembly of different populations of cells using the MLM, consistent generation of organoids termed adipospheres capable of simulating the complex intercellular interactions of endogenous white adipose tissue (WAT) can be achieved.

3D cell culturing by magnetic levitation 3 cells creates a vascular-like network assembly with concomitant lipogenesis in perivascular cells. See figure below. In addition to cell lines, WAT organogenesis can be simulated from primary cells. Adipocyte-depleted stromal vascular fraction (SVF) containing adipose stromal cells (ASC), endothelial cells, and infiltrating leukocyte derived from mouse white adipose tissue (WAT) were cultured in 3D. This revealed organoids striking in hierarchical organization with distinct capsule and internal large vessel-like structures lined with endothelial cells, as well as perivascular localization of ASC | Natural_sciences | https://en.wikipedia.org/wiki?curid=36845407 | 3D cell culturing by magnetic levitation |
3D cell culturing by magnetic levitation Upon adipogenesis induction of either 3T3-L1 adipospheres or adipospheres derived from SVF, the cells efficiently formed large lipid droplets typical of white adipocytes in vivo, whereas only smaller lipid droplet formation is achievable in 2D. This indicates intercellular signaling that better recapitulates WAT organogenesis. This MLM for 3D co-culturing creates adipospheres appropriate for WAT modeling ex vivo and provides a new platform for functional screens to identify molecules bioactive toward individual adipose cell populations. It can also be adopted for WAT transplantation applications and aid other approaches to WAT-based cell therapy.

Malcolm Steinberg (June 1, 1930 - February 7, 2012) was an American biologist who proposed the differential adhesion hypothesis as a mechanism explaining cell sorting during embryogenesis and cancer. Steinberg proposed that when cells form distinct tissues, specific cell-cell adhesion between cells from the same tissue can drive the separation. He further proposed that a difference in level of cell adhesion molecules expression between two cell types was sufficient to drive the separation. Steinberg pioneered work in characterizing the physical properties of cells and tissues. He proposed that cell-cell adhesion drives tissue rounding up and, comparing tissues to liquids, he proposed that tissues have a surface tension | Natural_sciences | https://en.wikipedia.org/wiki?curid=36899008 | Malcolm Steinberg |
Malcolm Steinberg To measure tissue surface tension, he participated in building a compression device for rounded tissues. Steinberg completed his BS at Amherst College in 1952, his PhD in zoology at the University of Minnesota in 1956, was a professor of biology at Johns Hopkins University from 1958 to 1966, and transferred to Princeton University in 1966, becoming professor emeritus in 2005. | Natural_sciences | https://en.wikipedia.org/wiki?curid=36899008 | Malcolm Steinberg |

Flux (biology) In general, flux in biology relates to movement of a substance between compartments. There are several cases where the concept of flux is important. Flux is the net movement of particles across a specified area in a specified period of time. The particles may be ions or molecules, or they may be larger, like insects, muskrats or cars. The units of time can be anything from milliseconds to millennia. Flux is not the same as velocity or speed nor is it the same as density or concentration. Movement itself is not enough. | Natural_sciences | https://en.wikipedia.org/wiki?curid=36911458 | Flux (biology) |

Kaigas The glaciation was a hypothesized snowball earth event in the Neoproterozoic Era, preceding the Sturtian glaciation. Its occurrence was inferred based on the interpretation of Formation conglomerates in the stratigraphy overlying the Kalahari Craton as correlative with pre-Sturtian Numees formation glacial diamictites. However, the formation was later determined to be non-glacial, and a Sturtian age was assigned to the Numees diamictites. Thus, there is no longer any evidence for a Neoproterozoic glaciation prior to the Sturtian snowball earth event. | Natural_sciences | https://en.wikipedia.org/wiki?curid=36951734 | Kaigas |

Claudia (crater) Claudia is a small (700 meter) crater that defines the prime meridian of asteroid 4 Vesta in the coordinate system used by the "Dawn" mission team, NASA, and the IAU "Gazetteer of Planetary Nomenclature", though it is not accepted by the IAU as a whole. It is located at 1.6°S and 4.0°W. Claudia was chosen because it is small, sharply defined, easy to find, and near the equator. The prime meridian runs 4° to the west. This results in a more logical set of mapping quadrants than the IAU coordinate system, which drifts over time due to an error in calculating the position of the pole, and is based on the 200 km Olbers Regio, which is so poorly defined that it is not even visible to the "Dawn" spacecraft | Natural_sciences | https://en.wikipedia.org/wiki?curid=37026545 | Claudia (crater) |

Geologic overpressure in stratigraphic layers is caused by the inability of connate pore fluids to escape as the surrounding mineral matrix compacts under the lithostatic pressure caused by overlying layers. Fluid escape may be impeded by sealing of the compacting rock by surrounding impermeable layers (such as evaporites, chalk and cemented sandstones). Alternatively, the rate of burial of the stratigraphic layer may be so great that the efflux of fluid is not sufficiently rapid to maintain hydrostatic pressure. Common situations where overpressure may occur: in a buried river channel filled with coarse sand that is sealed on all sides by impermeable shales, or when there is an explosion within a confined space | Natural_sciences | https://en.wikipedia.org/wiki?curid=37039369 | Geologic overpressure |
Geologic overpressure It is extremely important to be able to diagnose overpressured units when drilling through them, as the drilling mud weight (density) must be adjusted to compensate. If it is not, there is a risk that the pressure difference down-well will cause a dramatic decompression of the overpressured layer and result in a blowout at the well-head with possibly disastrous consequences. Because overpressured sediments tend to exhibit better porosity than would be predicted from their depth, they often make attractive hydrocarbon reservoirs and are therefore of important economic interest. | Natural_sciences | https://en.wikipedia.org/wiki?curid=37039369 | Geologic overpressure |
SeaDataNet is an international project of oceanography. Its main goal is to enable the scientific community to access historical datasets owned by national data centers. This project aims to provide a web service permitting to retrieve validated datasets (temperature, oxygen, salinity, nutrients, etc.) from 45 different National Data Centers of 35 countries having coasts along European seas. Therefore is a standardized system for managing the large and diverse data sets collected by the oceanographic fleets and the automatic observation systems. Additional objectives consist in creating product with aggregated data such as climatological descriptions | Natural_sciences | https://en.wikipedia.org/wiki?curid=37060172 | SeaDataNet |
SeaDataNet This European funded project has started in 2004, the project is currently in its second phase with fundings for 2012 to 2016. Most of the datasets are free of access, but some are restricted to institutes. In term of harmonization has chosen standards, vocabularies, tools that are used in the different NODC(National Oceanographic Data Center). For example they use Ocean Data View to validate or visualize datasets, they also use DIVA software to perform objective analysis. Datasets are covering the years 1800 up to 2012. In 2012 400 data originators are registered into Seadatanet project. Users of who want to retrieve datasets coming from multiple Data Centers log to the Common Data Index web-service to define their request | Natural_sciences | https://en.wikipedia.org/wiki?curid=37060172 | SeaDataNet |
SeaDataNet They can provide many details such as the type of platform wanted, the parameter wanted, the rate of sampling, the position, the originator country, etc. Then users send their request, the request is analysed and split into as much request as there are data centers concerned. At the end the user receive an email giving a FTP address where to retrieve all the data ordered in the file format wanted (ASCII, NetCDF or Ocean Data View format). | Natural_sciences | https://en.wikipedia.org/wiki?curid=37060172 | SeaDataNet |

Chemically induced dimerization Chemically Induced Dimerization (CID) is a biological mechanism in which two proteins bind only in the presence of a certain small molecule, enzyme or other dimerizing agent. Genetically engineered CID systems are used in biological research to control protein localization, to manipulate signalling pathways and to induce protein activation. The first small molecule CID system was developed in 1993 and used FK1012, a derivative of the drug tacrolimus (FK506), to induce homo-dimerization of FKBP. This system was used "in vivo" to induce binding between cell surface receptors which could not bind in the normal way because they lacked the transmembrane and extracellular domain. Addition of FK1012 to the cells caused signal transduction | Natural_sciences | https://en.wikipedia.org/wiki?curid=37102865 | Chemically induced dimerization |
Chemically induced dimerization CID has been used for a number of applications in biomedical research. In most applications each dimerizing protein is expressed as part of a fusion construct with other proteins of interest. Adding the chemical dimerizing agent brings both constructs into proximity with each other and induces interactions between the proteins of interest. CID has been used to regulate and monitor gene transcription, signal transduction and post translational modifications in proteins. Recently, CID has also been used to create a basic component of biocomputers, logic gates, from genetically manipulated cells. In this application, two independent CID systems, one based on plant proteins and one based on bacterial proteins are expressed in the same cell | Natural_sciences | https://en.wikipedia.org/wiki?curid=37102865 | Chemically induced dimerization |
Chemically induced dimerization Each set of proteins can be induced to dimerize by the addition of a separate chemical. By creating fusion proteins with the dimerizing proteins, membrane bound proteins and proteins that activate cell ruffling an AND gate and OR gate can be created that take chemical dimerizing agents as inputs and returns a ruffled or unruffled state as output. | Natural_sciences | https://en.wikipedia.org/wiki?curid=37102865 | Chemically induced dimerization |

Process study is the phenomenological approach used in climatology. Process studies are used "to develop the parameterizations [e.g. of circulation models], and observations [are] used to calibrate [the latter]". A parametrization is a set of fitted equations to represent physical phenomena instead of deducing them from first principals. An example for a parametrized phenomenon are thunderstorms which cannot be simulated within a circulation model if the spatial resolution of several km is too coarse to resolve single storm cell. There is a journal entitled "Process Studies". | Natural_sciences | https://en.wikipedia.org/wiki?curid=37133937 | Process study |

Capped octahedral molecular geometry In chemistry, the capped octahedral molecular geometry describes the shape of compounds where seven atoms , or groups of atoms or ligands are arranged around a central atom defining the vertices of a gyroelongated triangular pyramid. This shape has C symmetry and is one of the three common shapes for heptacoordinate transition metal complexes, along with the pentagonal bipyramid and the capped trigonal prism. Examples of the capped octahedral molecular geometry are the heptafluoromolybdate () and the heptafluorotungstate () ions. The "distorted octahedral geometry" exhibited by some AXE molecules such as xenon hexafluoride (XeF) is a variant of this geometry, with the lone pair occupying the "cap" position. | Natural_sciences | https://en.wikipedia.org/wiki?curid=37191231 | Capped octahedral molecular geometry |

Rotatum In physics, rotatum is the derivative of torque with respect to time. Expressed as an equation, rotatum Ρ is: where τ is torque and formula_2 is the derivative with respect to time formula_3. The term "rotatum" is not universally recognized but is commonly used. This word is derived from the Latin word "rotātus" meaning to rotate. The units of rotatum are force times distance per time, or equivalently, mass times length squared per time cubed; in the SI unit system this is kilogram metre squared per second cubed (kg·m/s), or Newtons times meter per second (N·m/s). Newton's second law for angular motion says that: where L is angular momentum, so if we combine the above two equations: where formula_6 is moment of Inertia and formula_7 is angular velocity | Natural_sciences | https://en.wikipedia.org/wiki?curid=37202680 | Rotatum |

Nuclear transparency is the ratio of cross-sections for exclusive processes from the nuclei to those of the nucleons. If a nuclear cross-section is denoted as formula_1 and free nucleon cross-section as formula_2, then nuclear transparency can be defined as formula_3, where formula_1 can be parameterized in terms of formula_2 as formula_6. Therefore, transparency can be expressed as formula_7. Here, nucleon cross-section can be thought of as a hydrogen cross-section, and nuclei cross-section can be as for other targets. | Natural_sciences | https://en.wikipedia.org/wiki?curid=37237547 | Nuclear transparency |
Swift J1745-26 is a stellar-mass black hole located a few degrees from the center of the Milky Way galaxy toward the constellation Sagittarius. It was discovered by NASA's Swift satellite on September 16, 2012 due to the detection of an X-ray nova. The pattern of X-rays from the nova indicated that the central object was a black hole. Its name arises from the coordinates of its sky position. While astronomers do not know its precise distance, they think the object resides about 20,000 to 30,000 light-years away in the galaxy's inner region. Ground-based observatories have detected infrared and radio emissions from Swift J1745-26, but thick clouds of obscuring dust have prevented astronomers from catching in visible light | Natural_sciences | https://en.wikipedia.org/wiki?curid=37259281 | Swift J1745-26 |
