Being slow to change in response to warming temperatures could have serious repercussions for long-distance migrant birds. Many birds are arriving earlier each spring as temperatures warm along the East Coast of the United States. However, the farther those birds journey, the less likely they are to keep pace with the rapidly changing climate.

Thinking ahead: Bacteria anticipate coming changes in their environment
June 19, 2008 08:57 AM - Princeton University, Engineering School

Microbes may be smarter than we think. A new study by Princeton University researchers shows for the first time that bacteria don't just react to changes in their surroundings -- they anticipate and prepare for them. The findings, reported in the June 6 issue of Science, challenge the prevailing notion that only organisms with complex nervous systems have this ability.

The Geobulb is a 8 watt LED light that replaces a 60 watt incandescent bulb. It generates 800 lumens of light to be exact — either warm white light or cool white. This bulb has a sleeker design than some of the LED lights I’ve seen check out that aesthetically pleasing heat sink.

It's the way you say it: using the right words can cut environmental conflicts
June 18, 2008 09:32 AM - Wiley-Blackwell

Ecologists have developed a new "tool" that could in future help prevent costly and acrimonious environmental conflicts such as campaigns against culling problem populations of charismatic animals and arguments over genetically modified organisms.
