New Research Shows Dinosaurs May Have Been Smaller Than We Thought
For millions of years, dinosaurs have been considered the largest creatures ever to walk on land. While they still maintain this status, a new study suggests that some dinosaurs may actually have weighed as little as half as much as previously thought.

Effective solar cells and sensitive bioanalysis
The efficiency factor of solar cells is crucial for the success of generating electricity from sunlight. Systems in which light is concentrated 400-fold through lenses onto solar cells are proving to be particularly advantageous.

In the warming West, climate most significant factor in fanning wildfires' flames
The recent increase in area burned by wildfires in the Western United States is a product not of higher temperatures or longer fire seasons alone, but a complex relationship between climate and fuels that varies among different ecosystems.

University of Houston research team aims to help caregivers monitor patients' health and whereabouts
For those who are caring for elderly parents, peace of mind is hard to come by. And, for their parents, dignity is hard to retain. But a team of University of Houston researchers hopes to ease worries and frustrations by designing an affordable in-home health-monitoring system that will notify caregivers, via smartphones or PDAs, if their loved ones need attention.
