A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of exciting science opportunities next decade. The Large Synoptic Survey Telescope (LSST) have an effective aperture 6.7 meters and imaging camera field view 9.6 deg^2, be devoted ten-year 20,000 deg^2 south +15 deg. Each pointing imaged 2000 times fifteen second exposures six broad from 0.35 1.1 microns, total point-source depth r~27.5. LSST Science Book describes basic...
In transgenic mice, self-reactive B lymphocytes are eliminated if they encounter membrane-bound self antigens during their development within the bone marrow. We show here that two separate and sequential events, arrested cell death, bring about elimination. Developmental arrest is an early outcome of antigen binding in immature cells, blocks acquisition adhesion molecules receptors important for migration activation, rapidly reversible by removal antigen. Death cells occurs 1 to 3 days can...
Mouse lymphoma cells in culture which are killed by adrenal steroids contain specific cortisol receptors that may be involved the initial events of hormone action. The similarity these to those hepatoma tissue cells, where induce tyrosine aminotransferase, suggests certain aspects steroid action similar two systems. In three steroid-resistant cell populations binding was less than parent lines, suggesting conversion resistance associated with changes binding.
Abstract Interferon‐γ (IFN‐γ), tested in the form of product a cloned murine IFN‐γ gene, was found to increase expression H‐2 antigens on cultured cell lines wide variety types including factor‐dependent hemopoietic cells, pre‐B and B macrophages, T mast cells epithelial, fibroblastic neuronal origin. However, induced Ia only macrophages T‐dependent or persisting cells. On basis these results, we suggest that major function is potentiate immune responses by enhancing types.
Abstract 1I/‘Oumuamua is the first confirmed interstellar body in our solar system. Here we report on observations of ‘Oumuamua made with Spitzer Space Telescope 2017 November 21–22 (UT). We integrated for 30.2 hr at 4.5 μ m (IRAC channel 2). did not detect object and place an upper limit flux 0.3 Jy (3 σ ). This implies effective spherical diameter less than [98, 140, 440] albedo greater [0.2, 0.1, 0.01] under assumption low, middle, or high thermal beaming parameter η , respectively. With...
