Will Global Change Increase Fire Activity In The Mediterranean Basin?
...will argue, based on his studyof landscape pattern using
a GIS, that land use changes, in particular cropabandonment -resulting in a greater landscape homogeneity- and the introductionof flammable species such as the pine, have contributed to increased firesusceptibility in the last 20 years. Dr. J. Moreno...
Biologists Get First Look At DNA-Protein Binding Structure In An Archaeon
...three-dimensional structure of the binding complex using
X-ray diffraction. The result is a definitive, very-detailed picture of protein binding with DNA. The binding complex is "a buried box-shaped cavity" between the protein and DNA surfaces, where there are four water molecules, the authors wrote. The...

Mouse Gene Reveals Clues To Human Deafness
...When the human form of the same gene was sequenced using
DNAfrom hearing-impaired individuals in the Israeli family, a mutation was found ina critical part of the gene. Deaf members of the Israeli family carry two forms of the gene: onenormal and one mutant. Initially, the normal gene appears to be...
