Second Harvest

winterYour vegetable garden is most likely at its peak of production right about now, with basketloads of summer favorites ripening every day. In just a few short weeks, though, the season for tomatoes, cucumbers, and other warm-weather crops ends. Good news: You don't have to wait until next spring to harvest more fresh vegetables from your garden. This week, you can plant a variety of crops that thrive in the cool temperatures of fall and some that even tolerate winter temperatures in the North. (more…)

Plant Street Trees to Clean the Air

plantreePlanting trees is good for the environment, good for the soul, good for the local economy... and, it turns out, even better for our health than previously thought.

A recent study published in Environmental Science & Technology found that trees and other green plants can reduce two key air pollutants eight times more than previously known.

Nitrogen dioxide and fine particulates are two key components of smog and soot, which can damage lungs, make outdoor exercise unsafe and send asthmatics running to the emergency room at high rates. Both pollutants, however, can be reduced by as much as 40% (nitrogen dioxide) to 60% (fine particulates) if trees, shrubs, ivy and even grass are planted in so-called "urban street canyons." Trees, in fact, may be less effective than smaller greenery, since pollutants may be trapped beneath the tree canopy in some cases. (more…)

Make a simple microbial fuel cell



Instructable user drdan152 let us share his cool project for making a microbial fuel cell, a technology that harvests electrons that are a byproduct of bacteria breaking down organic matter to produce electricity, at home. This project lets you get up close with the science behind microbial fuel cells and learn about this type of renewable energy technology. (more…)

Silver nanoparticles in porous gel becomes bacteria-killing sponge for water purification

waterAfter natural disasters, one critical element necessary for human survival is clean, drinkable water, which can be hard to come by if the water infrastructure is damaged or tainted. While there already are plenty of solutions for filtering and purifying water, some of them require access to power, or they are too slow or too expensive to effectively meet the drinking water needs of large amounts of people.

Smart window coating lets you control how much light and heat get through

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a breakthrough new material that could lead to smart windows where people could control the amount of light and heat (both together or separately) that gets through. This new technology could make homes and businesses much more energy efficient. (more…)
