Increasing Levels of Carbon Dioxide Effecting our Plants?

In an article posted to the St. Louis Public Radio website, written by Eli Chen, we find information on how a study is going to measure the increasing level of carbon dioxides effects on plants. A four-year study starting now, by scientists at the Donald Danforth Plant Science Center and Washington University, is being performed to find out what the effects of long-term exposure to carbon dioxide has on plants. Today carbon dioxide levels are at an all-time high and are only expected to increase if there is continual use of fossil fuels and other natural resources. In this study...

How Heat from the Sun Can Keep Us All Cool

Seven thousand kilometers to the west, in dry Khartoum, Sudan, patients rest in a United Nations Hospital, cocooned from the baking desert heat. In both buildings, the pleasant conditions come courtesy of air-conditioning units that rely in part on dark glass tubes that turn sunlight into cooling power. These aren’t the familiar solar panels that harvest light to make electricity. Instead, they harness heat from the Sun to chill buildings through a neat bit of...
