Healthy forests, healthy fires, healthy bats
Do no harm. In the effort to manage the forest habitats of the endangered Indiana bat, naturalists must always, always, first consider the impact on this nocturnal mammal. Bats perform a vital ecological role, feeding entirely on flying insects; a single bat can consume thousands of mosquitoes each night.
New material could improve efficiency of solar power
Ohio State University chemists and their colleagues have created a new material that overcomes two of the major obstacles to solar power: it has an absorption spectrum that closely matches that of the solar spectrum, and it generates long-lived excited electrons that should allow solar cells to generate electricity more efficiently.
