Prideful talk of new missiles, submarines, and bombers actually reveals weak Russian leadership and a stubborn military-industrial complex that’s preparing to fight yesterday’s wars.

In 2008, the United States will spend more than $600 billion on defense, including funding for the Iraq War. If Congress adds the remainder of what President George W. Bush has requested for Iraq and Afghanistan, spending will top $700 billion.
Human ingenuity will ultimately wean the world off of fossil fuels, and the rising cost of oil will inspire that ingenuity sooner rather than later.
Over the past year, it’s become clear that the way the political and environmental communities are approaching global warming isn’t going to solve it.
The traditional concern about Iran’s capability to deliver a nuclear weapon involves an Iranian ballistic missile that could reach the United States from Iran. Therefore, in this piece I describe the current state and expected time when Iran could achieve these capabilities on the basis of recent statements by U.S.
The recently released National Intelligence Estimate on Iran’s nuclear program seemed to contradict Bush administration claims and left many in China puzzled.
In December 2003, President George W. Bush signed the Twenty-first Century Nanotechnology Research & Development Act, establishing a framework for enabling what some have described as “the next industrial revolution.” Four years on, the act is up for reauthorization. As legislators grapple with how the nanotechnology landscape has changed in the intervening years, they face the complex task of continuing to ensure U.S. leadership in the development of nanotechnologies that are successful, sustainable, and above all, safe.
It’s challenging to model disease spread during epidemics. Simple mathematical models such as the “general epidemic” model make assumptions about constant population size, homogeneous mixing, and constant recovery rates, but can only go so far in predicting an outbreak’s severity (See “Mathematical Modeling of Epidemics”).
With primary season upon us, the presidential candidates have been busy debating and making policy presentations so that we can begin to glean some ideas of their views on everything from the economy to national defense. As is often the case, the media haven’t focused on the candidates’ views on technical issues, but in the end, these may be among the most significant issues that the next president will face.
The Intergovernmental Panel on Climate Change (IPCC), long regarded as the single most trustworthy source of information on climate science, states unequivocally that Earth’s climate is warming rapidly and that we’re now more than 90 percent certain that human activities have caused most of the observed warming in recent decades. The research behind these findings, published in the IPCC’s landmark 2007 report, is rock-solid science.
It’s estimated that about 10 million people in the United States (3.6 percent of the population) are immunocompromised. But that’s likely an underestimate because it only includes those with HIV/AIDS (diagnosed and undiagnosed), organ transplant recipients, and cancer patients; there’s a sizable population that takes immunosuppressive drugs for other disorders such as rheumatoid arthritis and inflammatory bowel disease.
