Tropical Cyclone Nargis slammed the Burmese coast with 130 mph winds and bursts of up to 160 mph—the equivalent of a category 3 or low-level category 4 hurricane. It reportedly led to thousands of deaths, and as of Monday, thousands more were missing. Now NASA has released a set of images that show how drastically the flooding has drenched Burma's coast.

Flowers are known to attract pollinating insects through a variety of means, from alluring fragrances and nectar to vibrant colors and shapes. According to a new study in the Read Full Story ]

Bioplastics, like biofuels, are on the rise as consumers demand alternatives to fossil fuel-based plastics and big business take their wants seriously. Everything from shopping bags to clamshell containers are being reengineered out of bio-based packaging in the hope of finding a truly disposable container; one that, instead of ending up floating in the ocean, will quickly decompose underground. That ideal, as you might expect, is not quite so simple. And already, our two leading alternative bag types are falling short of the hype.

With a death toll steadily rising, the effects of Myanmar's devastating cyclone have yet to be quantified, but days after the storm one thing is clear: they will be long-lasting and far-reaching.

"Our biggest fear is that the aftermath could be more lethal than the storm itself," said Caryl Stern, head of the U.N. Children's Fund. Four days on, electricity and water supplies are still cut throughout the country. With broken sewage lines, mounting trash, impassable roads preventing access to clean water and food, and damaged hospitals, the nation faces a likely-devastating public health crisis. The World Health Organization has pinpointed malaria and tuberculosis—two diseases that thrive amidst overcrowding and bad water—as especial threats. Meanwhile, the spread of communicable diseases is speeded by blocked roads, which trap sick people in and keep health workers out.

If you live in a major metropolitan city, you've perhaps noticed that the sidewalks are covered with black dots the size of quarters. I remember it took me a few months after moving to New York City to figure out that was gum. After it's spit out, it gets stepped on and flattened to the concrete. In no time at all it accumulates the ebony patina of city grime. Sprinkling the sidewalks is easy. Removing the tarred, synthetic rubber is the hard part. If you're talking about one chewed stick in a school hallway, it's a can of solvent and a putty knife away from coming off the floor.

There is an element of "why did it take so long?" in reports surfacing of the zero-watt monitor from Fujitsu Siemens. It's a flat panel LCD which contains a relay switch that automatically interrupts the power supply when the video signal from an attached PC subsides. Instead of going into standby when idle and consuming a low voltage, the monitor consumes none at all. When the video signal returns, the relay switches the other way and electricity is returned to power up the monitor.

MIT meteorologist Kerry Emanuel got a ton of attention in 2005 when he published a paper in Nature demonstrating a link between global warming and hurricanes—especially since Katrina hit New Orleans just three weeks later.

When it comes to climate change, a quick fix won't do. Science published a paper Friday from the National Center for Atmospheric Research (NCAR) which concludes that a proposed plan to inject the atmosphere with sulfate particles in order to cool the planet would actually have dire consequences.

The good news is that the ozone hole over Antarctica is slowly healing, thanks to controls on ozone-depleting substances that were once widely used in products such as refrigerators and aerosol cans. Stratospheric ozone protects us from harmful ultraviolet radiation that can cause problems such as skin cancer and crop damage.

If we don't get our act together in time and we push this planet past its limits, to the point where things get disaster-movie bad, at the very least we can take solace in the fact that we've been there once before. According to new research out of Stanford University, the human species was on the brink of extinction 70,000 years ago due to an extended drought. It shrunk the human population to a number perhaps as low as 2,000.
