Whither Do the Microlensing Brown-dwarfs Rove?
The EROS and MACHO collaborations have reported observations of light curves of stars in the Large Magellanic Cloud that are compatible with gravitational microlensing by intervening massive objects, presumably BrownDwarf stars. The OGLE and MACHO teams have also seen similar events in the direction of the galactic Bulge. Current data are insufficient to decide whether the Brown-Dwarfs are dark...
متن کاملDo sweetening agents interact with morphine-induced analgesia in the formalin test in mice?
There is evidence that sweeteners such as sucrose and saccharin interact with endogenous opioid systems. Further research has shown that feeding different concentrations of sucrose and saccharin alter latency in the tail-flick test. In this study, the influence of a 12-day regimen of different sweetening agents, sucrose (32%), saccharin (0.08%) and aspartame (0.16%) on morphine-induced analge...
متن کاملMagellanic Cloud Gravitational Microlensing Results: What Do They Mean?
Recent results from gravitational microlensing surveys of the Large Magellanic Cloud are reviewed. The combined microlensing optical depth of the MACHO and EROS-1 surveys is τLMC = 2.1 +1.3 −0.8 × 10 which is substantially larger than the background of τback ≤ 0.5 × 10 −7 from lensing by known stellar populations although it is below the expected microlensing optical depth of τ = 4.7 × 10 for a...
متن کاملWhither the RMA?
The strategic importance of technological improvements in US military capability is a key but insufficiently examined issue in the transformation of today’s military. Is the present Department of Defense (DOD) attempt at transformation, which focuses on technological solutions to increase capabilities, being misguided by a vision of a high-tech Revolution in Military Affairs (RMA)? This questio...
متن کاملWhither Magnesium?
Magnesium is a chemical element with the atomic number 12, an atomic weight of 24, and the common oxidation number 12. Magnesium is an alkaline metal and the eighth most abundant element in the Earth’s crust, where it constitutes about 2% by mass, and ninth in the Universe. Magnesium is easily built up in supernova stars by the sequential addition of three helium nuclei to carbon. Magnesium ion...
