Green Until The Very End

An assortment of green burial options, from high-concept to just-plain-gross, are becoming a reality for the environmentally conscious

Worried that embalming fluids or emissions from cremation will pollute the earth after your death? There may be a more eco-friendly albeit somewhat grisly alternative—dissolving the body in lye. The process, which has been used to dispose of animals and lab specimens for many years, is now being considered more seriously for human use. Called alkaline hydrolysis, the method uses a steel cylinder that dissolves the body in lye with 300-degree heat and 60 pounds of pressure per square inch. The result is a sterile, coffee-colored liquid with the consistency of motor oil that can be safely poured down the drain. A small amount of bone residue that can be scattered like cementation ashes is the only solid byproduct.

The Growing Problem of Food Waste

Despite food shortages worldwide, a culture of waste pervade the U.S. and Britain

In the current climate of rising gas and food prices, it should stand to reason that people would find ways to change their most wasteful habits. According to new research from the UK, we need look no further than our own refrigerators. Fully 18 percent of all food purchased for household use in England and Wales is thrown away. The number is even higher for families with children at 27 percent. A now four year-old study of similar measure in the U.S. puts the American number around 14 percent, with nearly half of all food readied for harvest never making it to a dinner table.

Satellite Images of Devastation in Burma

NASA's Terra satellite captures startling before and after pictures of the coast of Burma

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.

New Study: Flowers Attract Insects with Movement

Think blooms lure bugs just by smelling good and looking pretty? Not so, new research shows

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 ]

The Problem With (Bio)plastic

The so-called solution to our eco-woes is quickly proving nearly as troublesome as the issue itself

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.

Ripple Effect in the Wake of Cyclone Nargis

A natural disaster that may have been preventable has a global impact

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.

High Tech Gum Remover

A cheaper and greener way to remove that scourge of urban sidewalks

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.

Zero Watt Monitor

Leave your monitor on standby without the eco-guilt

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.

Hurricane, Climate Change Link Explained

MIT professor Kerry Emanuel tries to correct the misinterpretations of his latest research

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.

The Risks of Geoengineering

One proposed fix for the planet's climate problems could create more problems than it solves

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.
