Garbage. Americans produce more and more of it every year, when we need to be producing less. Even the most waste-conscious among us can feel overwhelmed by the amount of household waste that goes beyond what municipal recyclers and compost bins can handle. That’s why our editors spent the summer of 2007 investigating the state of waste management in our country, putting this list togther for you, explaining how we can get serious about the three R’s – reducing, reusing, and recycling — and divert more waste away from landfills.

ATHENS (Reuters) - An earthquake measuring 6.5 on the Richter scale struck Greece on Sunday, shaking people out of bed and sending panic-stricken villagers into the streets but there were no immediate reports of casualties or damage.

Greece is often rattled by earthquakes, most causing no serious damage.

North Atlantic Warming Tied To Natural Variability
January 5, 2008 04:14 PM - Duke University

This striking pattern can be explained largely by the influence of a natural and cyclical wind circulation pattern called the North Atlantic Oscillation (NAO), wrote authors of a study published Jan. 3, in Science Express, the online edition of the journal Science. Winds that power the NAO are driven by atmospheric pressure differences between areas around Iceland and the Azores. "The winds have a tremendous impact on the underlying ocean," said Susan Lozier, a professor of physical oceanography at Duke's Nicholas School of the Environment and Earth Sciences who is the study's first author.

Northern plants 'losing carbon' due to warming
January 5, 2008 04:05 PM - , SciDevNet

[BEIJING] Global warming could cause plants in northern regions to lose carbon to the atmosphere rather than sequester it, according to a new international study. The research, published in Nature yesterday (3 January), looked at atmospheric carbon dioxide concentrations and carbon dioxide held in ecosystems such as forests in the Northern Hemisphere in the past 20 years.

Snow water is an important factor for determining the coming year's water supply for hydroelectric generation, as well as the reservoir level for the state and local water supply. California gets more than 17 percent of its power from hydroelectric generation, according to the California Energy Commission.

Smell-wars between butterflies and ants
January 4, 2008 09:08 AM - University of Copenhagen

Among humans, making yourself smell more alluring than you really are is a fairly harmless, socially accepted habit that maintains a complete perfume industry. However, it is a matter of life and death for caterpillars of large blue butterflies that dupe ant workers into believing them to be one of the ant’s own larvae. In a publication in the journal Science this week , researchers from the Centre for Social Evolution (CSE) at the University of Copenhagen show that caterpillar deception is also a matter of smell, and that there is an ongoing co-evolutionary arms race in smell similarity between cheaters and their victims.
