Often growing far above the ground, "air plants" (or epiphytes) defy many of our common perceptions about plants. The majority use their roots only for attachment in the crowns of larger, usually woody plants—or to objects such as rocks and buildings—and derive moisture and nutrients from the atmosphere and by collecting falling debris. Only the mistletoes are true parasites. Epiphytes are not anomalies and there are approximately 28,000 species—about 10 percent of the hig...

Universal health care was on the national political agenda for nearly a hundred years until a comprehensive (but not universal) health care reform bill supported by President Obama passed in 2010. The most common explanation for the failure of past reform efforts is that special interests were continually able to block reform by lobbying lawmakers. Yet, beginning in the 1970s, accelerating with the failure of the Clinton health care plan, and continuing through the passage of the Affordabl...

50,000 years ago – merely a blip in evolutionary time – our Homo sapiens ancestors were competing for existence with several other human species, just as their own precursors had been doing for millions of years. Yet something about our species separated it from the pack, and led to its survival while the rest became extinct. So just what was it that allowed Homo sapiens to become Masters of the Planet? Curator Emeritus at the American Museum of Natural History, Ian Tatte...

One of the most urgent challenges in African economic development is to devise a strategy for improving statistical capacity. Reliable statistics, including estimates of economic growth rates and per-capita income, are basic to the operation of governments in developing countries and vital to nongovernmental organizations and other entities that provide financial aid to them. Rich countries and international financial institutions such as the World Bank allocate their deve...

"Keep your government hands off my Medicare!" Such comments spotlight a central question animating Suzanne Mettler's provocative and timely book: why are many Americans unaware of government social benefits and so hostile to them in principle, even though they receive them? The Obama administration has been roundly criticized for its inability to convey how much it has accomplished for ordinary citizens. Mettler argues that this difficulty is not merely a failure of communication; rather i...

A world without bees would be much less colourful, with fewer plants and flowers. But that's not all -- food would be in much shorter supply, and available in much less variety. While the media focuses on colony-collapse disorder and the threats to honey bees specifically, the real danger is much greater: all bees are at risk. And because of the integral role these insects play in the ecology of our planet, we may be at risk as well.The life of Laurence Packer, a melittologist at T...
