In the highly competitive world of international politics, nation states very rarely miss an opportunity to crow about success stories. The opportunity comes rare, mostly by default, and seldom enduring. By any standards of showmanship, therefore, Tehran has set a new benchmark of reticence. By all accounts, Iran played a decisive role in hammering out the peace deal among the Shi’ite factions in Iraq. A bloody week of human killing on the Tigris River ended on Sunday. Details are sketchy, however, since they must come from non-Iranian sources. Tehran keeps silent about its role. The deal was brokered after negotiations in the holy city of Qom in Iran involving the two Shi’ite factions – the Da’wa Party and the Supreme Islamic Iraqi Council (SIIC) – which have been locked in conflict with Muqtada al-Sadr’s Mahdi Army in southern Iraq. It appears that one of the most shadowy figures of the Iranian security establishment, General Qassem Suleimani, commander of the Quds Force of Iranian Revolutionary Guards Corps (IRGC) personally mediated in the intra-Iraqi Shi’ite negotiations. Suleimani is in charge of the IRGC’s operations abroad. US military commanders routinely blame the Quds for all their woes in Iraq. The […]
WASHINGTON, D.C. — ‘With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close,’Â says Lester R. Brown, President, and Jonathan G. Dorn, Staff Researcher, of Earth Policy Institute, in a recent release, ‘The Beginning of the End for Coal: A Long Year in the Life of the U.S. Coal Industry’Â. In early 2007, a U.S. Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 coal plants are being contested in the courts, and the remaining plants will likely be challenged when they reach the permitting stage. What began as a few local ripples of resistance to coal-fired power plants is quickly evolving into a national tidal wave of opposition from environmental, health, farm, and community organizations as well as leading climate scientists and state governments. Growing concern over pending legislation to regulate carbon emissions is creating uncertainty in financial markets. Leading financial groups are now downgrading coal stocks and requiring utilities seeking funding for coal plants to […]
A New York University dental professor has discovered a biological clock linking tooth growth to other metabolic processes. This clock, or biological rhythm, controls many metabolic functions and is based on the circadian rhythm, which is a roughly 24-hour cycle that is important in determining sleeping and feeding patterns, cell regeneration, and other biological processes in mammals. The newly discovered rhythm, like the circadian rhythm, originates in the hypothalamus, a region of the brain that functions as the main control center for the autonomic nervous system. But unlike the circadian rhythm, this clock varies from one organism to another, operating on shorter time intervals for small mammals, and longer ones for larger animals. For example, rats have a one-day interval, chimpanzees six, and humans eight. NYU dental professor Dr. Timothy Bromage discovered the rhythm while observing incremental growth lines in tooth enamel, which appear much like the annual rings on a tree. He also observed a related pattern of incremental growth in skeletal bone tissue — the first time such an incremental rhythm has ever been observed in bone. Reporting his findings at the 37th Annual Meeting of the American Association for Dental Research, Bromage said, […]
The accuracy of computer models that predict climate change over the coming decades has been the subject of debate among politicians, environmentalists and even scientists. A new study by meteorologists at the University of Utah shows that current climate models are quite accurate and can be valuable tools for those seeking solutions on reversing global warming trends. Most of these models project a global warming trend that amounts to about 7 degrees Fahrenheit over the next 100 years. In the study, co-authors Thomas Reichler and Junsu Kim from the Department of Meteorology at the University of Utah investigate how well climate models actually do their job in simulating climate. To this end, they compare the output of the models against observations for present climate. The authors apply this method to about 50 different national and international models that were developed over the past two decades at major climate research centers in China, Russia, Australia, Canada, France, Korea, Great Britain, Germany, and the United States. Of course, also included is the very latest model generation that was used for the very recent (2007) report of the Intergovernmental Panel on Climate Change (IPCC). ‘Coupled models are becoming increasingly reliable tools […]
WASHINGTON — Army leaders are expressing increased alarm about the mental health of soldiers who would be sent back to the front again and again under plans that call for troop numbers to be sustained at high levels in Iraq for this year and beyond. Among combat troops sent to Iraq for the third or fourth time, more than one in four show signs of anxiety, depression or acute stress, according to an official Army survey of soldiers’ mental health. The stress of long and multiple deployments to Iraq is just one of the concerns being voiced by senior military officers in Washington as Gen. David H. Petraeus, the senior Iraq commander, prepares to tell Congress this week that he is not ready to endorse any drawdowns beyond those already scheduled through July. President Bush has signaled that he will endorse General Petraeus’s recommendation, a decision that will leave close to 140,000 American troops in Iraq at least through the summer. But in a meeting with Mr. Bush late last month in advance of General Petraeus’s testimony, the Joint Chiefs of Staff expressed deep concern about stress on the force, senior Defense Department and military officials […]
