I’ve known about the problems of wind energy and the current power grid for quite a while. I found this article on The Energy Challenge — Wind Energy Bumps Into Power Grid Limits in the New York Times (you’ll need to login to read it). To clearly state the problem. In part: The grid today, […]
I’ve often wonder how people know things or how information spreads from one person to another. Not so much in an educational classroom sense but those things that you pick up in daily life. Then, the other day I ran across this article on Evolution and Facebook’s “25 Random Things”. The results of the questionnaire […]
Today an article in National Geographic News reports that liquid water was recently seen on Mars. Phoenix, which landed near Mars’ north pole, has taken several photos of itself and a recent series of photos seem to show water droplets on the lander’s legs that are clumping together and running downward. If it’s not water, […]
Sometimes when I read the results of a new scientific study, such as this one on “Loss of Height Linked to Breathlessness in the Elderly“, I wonder why they didn’t know that already. One researcher said: “The results of the study were far more profound that we expected, given the relatively small number of subjects […]
An article reports that scientists have mapped a first draft of the Neanderthal genome. Highlights of the article: Researchers used DNA fragments extracted from three Croatian fossils to map out more than 60 percent of the entire Neanderthal genome by sequencing three billion bases of DNA. The analysis showed it is highly unlikely that much […]
I came across this interesting article on EarthFirst and followed the link to a similar announcement on WorldChanging. Basically, the city of Oslo, Norway is going to start running their buses on biomethane. The WorldChanging article says: In Oslo, air pollution from public and private transport has increased by approximately 10% since 2000, contributing to […]
I don’t know about you but I’m always interested in new gadgets that will be better for the environment and greener to use. I’d never heard of this contest before but it’s their second year. The people at Core77: We invited designers to explore the concept of “Greener Gadgets.” Designs sought to minimize the environmental […]
Irreversible. That’s what a new study reported by NPR says: As carbon dioxide emissions continue to rise, the world will experience more and more long-term environmental disruption. The damage will persist even when, and if, emissions are brought under control, says study author Susan Solomon, who is among the world’s top climate scientists. I’ve heard […]
