    Description: Stem cells are defined as self-renewing cell populations that can differentiate into multiple distinct cell types. However, hundreds of different human cell lines from embryonic, fetal and adult sources have been called stem cells, even though they range from pluripotent cells-typified by embryonic stem cells, which are capable of virtually unlimited proliferation and differentiation-to adult stem cell lines, which can generate a far more limited repertoire of differentiated cell types. The rapid increase in reports of new sources of stem cells and their anticipated value to regenerative medicine has highlighted the need for a general, reproducible method for classification of these cells. We report here the creation and analysis of a database of global gene expression profiles (which we call the 'stem cell matrix') that enables the classification of cultured human stem cells in the context of a wide variety of pluripotent, multipotent and differentiated cell types. Using an unsupervised clustering method to categorize a collection of approximately 150 cell samples, we discovered that pluripotent stem cell lines group together, whereas other cell types, including brain-derived neural stem cell lines, are very diverse. Using further bioinformatic analysis we uncovered a protein-protein network (PluriNet) that is shared by the pluripotent cells (embryonic stem cells, embryonal carcinomas and induced pluripotent cells). Analysis of published data showed that the PluriNet seems to be a common characteristic of pluripotent cells, including mouse embryonic stem and induced pluripotent cells and human oocytes. Our results offer a new strategy for classifying stem cells and support the idea that pluripotency and self-renewal are under tight control by specific molecular networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2637443/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2637443/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muller, Franz-Josef -- Laurent, Louise C -- Kostka, Dennis -- Ulitsky, Igor -- Williams, Roy -- Lu, Christina -- Park, In-Hyun -- Rao, Mahendra S -- Shamir, Ron -- Schwartz, Philip H -- Schmidt, Nils O -- Loring, Jeanne F -- K12 5K12HD000849-20/HD/NICHD NIH HHS/ -- P20 GM075059/GM/NIGMS NIH HHS/ -- P20 GM075059-01/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Sep 18;455(7211):401-5. doi: 10.1038/nature07213.

    Description: A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmological origin. It should carry unique signatures from the earliest epochs in the evolution of the Universe, inaccessible to standard astrophysical observations. Direct measurements of the amplitude of this background are therefore of fundamental importance for understanding the evolution of the Universe when it was younger than one minute. Here we report limits on the amplitude of the stochastic gravitational-wave background using the data from a two-year science run of the Laser Interferometer Gravitational-wave Observatory (LIGO). Our result constrains the energy density of the stochastic gravitational-wave background normalized by the critical energy density of the Universe, in the frequency band around 100 Hz, to be 〈6.9 x 10(-6) at 95% confidence. The data rule out models of early Universe evolution with relatively large equation-of-state parameter, as well as cosmic (super)string models with relatively small string tension that are favoured in some string theory models. This search for the stochastic background improves on the indirect limits from Big Bang nucleosynthesis and cosmic microwave background at 100 Hz.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉LIGO

    Description: The unique band structure of graphene allows reconfigurable electric-field control of carrier type and density, making graphene an ideal candidate for bipolar nanoelectronics. We report the realization of a single-layer graphene p-n junction in which carrier type and density in two adjacent regions are locally controlled by electrostatic gating. Transport measurements in the quantum Hall regime reveal new plateaus of two-terminal conductance across the junction at 1 and 32 times the quantum of conductance, e(2)/h, consistent with recent theory. Beyond enabling investigations in condensed-matter physics, the demonstrated local-gating technique sets the foundation for a future graphene-based bipolar technology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, J R -- Dicarlo, L -- Marcus, C M -- New York, N.Y. -- Science. 2007 Aug 3;317(5838):638-41.

    Description: Organic aerosol (OA) particles affect climate forcing and human health, but their sources and evolution remain poorly characterized. We present a unifying model framework describing the atmospheric evolution of OA that is constrained by high-time-resolution measurements of its composition, volatility, and oxidation state. OA and OA precursor gases evolve by becoming increasingly oxidized, less volatile, and more hygroscopic, leading to the formation of oxygenated organic aerosol (OOA), with concentrations comparable to those of sulfate aerosol throughout the Northern Hemisphere. Our model framework captures the dynamic aging behavior observed in both the atmosphere and laboratory: It can serve as a basis for improving parameterizations in regional and global models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jimenez, J L -- Canagaratna, M R -- Donahue, N M -- Prevot, A S H -- Zhang, Q -- Kroll, J H -- DeCarlo, P F -- Allan, J D -- Coe, H -- Ng, N L -- Aiken, A C -- Docherty, K S -- Ulbrich, I M -- Grieshop, A P -- Robinson, A L -- Duplissy, J -- Smith, J D -- Wilson, K R -- Lanz, V A -- Hueglin, C -- Sun, Y L -- Tian, J -- Laaksonen, A -- Raatikainen, T -- Rautiainen, J -- Vaattovaara, P -- Ehn, M -- Kulmala, M -- Tomlinson, J M -- Collins, D R -- Cubison, M J -- Dunlea, E J -- Huffman, J A -- Onasch, T B -- Alfarra, M R -- Williams, P I -- Bower, K -- Kondo, Y -- Schneider, J -- Drewnick, F -- Borrmann, S -- Weimer, S -- Demerjian, K -- Salcedo, D -- Cottrell, L -- Griffin, R -- Takami, A -- Miyoshi, T -- Hatakeyama, S -- Shimono, A -- Sun, J Y -- Zhang, Y M -- Dzepina, K -- Kimmel, J R -- Sueper, D -- Jayne, J T -- Herndon, S C -- Trimborn, A M -- Williams, L R -- Wood, E C -- Middlebrook, A M -- Kolb, C E -- Baltensperger, U -- Worsnop, D R -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1525-9. doi: 10.1126/science.1180353.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cooperative Institute for Research in the Environmental Sciences and Department of Chemistry and Biochemistry, University of Colorado, Boulder, CO, USA. jose.jimenez@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007897" target="_blank"〉PubMed〈/a〉

    Description: Aneuploidy, an incorrect number of chromosomes, is the leading cause of miscarriages and mental retardation in humans and is a hallmark of cancer. We examined the effects of aneuploidy on primary mouse cells by generating a series of cell lines that carry an extra copy of one of four mouse chromosomes. In all four trisomic lines, proliferation was impaired and metabolic properties were altered. Immortalization, the acquisition of the ability to proliferate indefinitely, was also affected by the presence of an additional copy of certain chromosomes. Our data indicate that aneuploidy decreases not only organismal but also cellular fitness and elicits traits that are shared between different aneuploid cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2701511/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2701511/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Bret R -- Prabhu, Vineet R -- Hunter, Karen E -- Glazier, Christina M -- Whittaker, Charles A -- Housman, David E -- Amon, Angelika -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):703-9. doi: 10.1126/science.1160058.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉David H.

    Description: In the Southern Ocean, biological production in sea ice is considered to be a major driving force for Antarctic animal population sizes and biodiversity. It is known that sea ice forms an important habitat for the Antarctic minke whale during the summer months when production is high. Sightings of minke whales during the austral winter in the pack ice were considered atypical and it has been thought that Antarctic minke whales (Balaenoptera bonaerensis) only stay in Antarctic waters during the austral summer and spend the winter breeding season in tropical and subtropical waters. However, continuing food availability under the sea ice during the winter months might also enable them to overwinter in the deep pack ice. Data on minke whale occurrence in Antarctic winter months is scarce, due to limited observation effort during this time, as well as due to difficult sighting conditions. This pilot study is a first attempt to compile and analyze existing data in order to investigate the seasonal use of sea ice by minke whales.
