In Hubble Catches End of Star-Making Party in Nearby Dwarf Galaxy, Science Daily summarizes a study recently published in The Astrophysical Journal – in essence, an intriguing short biographical sketch of the recent history of an unusual galaxy.
Writing in Forbes, Thomas F. Cooley of New York University’s Stern School of Business and Peter Rupert of the University of California, Santa Barbara’s Laboratory for Aggregate Economics and Finance offer a very elucidating brief discussion of the current economic recession in America’s Two Economies.
Nearly every segment of the American populace has been adversely affected by the current recession. State and local governments have in particular been squeezed by falling tax revenues and rising demand for vital services. How have they responded, and what impact have their various measures had upon the state and local governmental workforce?
A survey conducted by the Center for State & Local Government Excellence summarizes the extent of hiring freezes, pay freezes and cuts, layoffs, furloughs, and early retirement incentives, and analyzes the effects of those measures in The Great Recession and the State and Local Government Workforce.
If you’ve been keeping up with developments in the biological sciences, you’ve probably anticipated this one for quite some time. As described in this short article in Science Daily,
“For 80 years it has been accepted that early life began in a ‘primordial soup’ of organic molecules before evolving out of the oceans millions of years later. Today the ‘soup’ theory has been over turned in a pioneering paper in BioEssays which claims it was the Earth’s chemical energy, from hydrothermal vents on the ocean floor, which kick-started early life.
“‘Textbooks have it that life arose from organic soup and that the first cells grew by fermenting these organics to generate energy in the form of ATP. We provide a new perspective on why that old and familiar view won’t work at all,’ said team leader Dr Nick lane from University College London. ‘We present the alternative that life arose from gases (H2, CO2, N2, and H2S) and that the energy for first life came from harnessing geochemical gradients created by mother Earth at a special kind of deep-sea hydrothermal vent — one that is riddled with tiny interconnected compartments or pores.’”
