<jats:p>In ongoing litigation to determine whether silicone breast implants cause autoimmune disease, the question of what constitutes good science is being addressed by courts, and the answer has implications for approximately $50 billion in settlements. A federal court recently used neutral scientific advisers in excluding the admissibility of the “expert” opinion that implants cause systemic disease. The lesson from this litigation paradigm is that scientists should actively ensure that neutral, reliable scientific expertise is available to the court.</jats:p>

<jats:p>The Arecibo 12.6-centimeter wavelength radar system was used to image the polar regions of the moon at a resolution of 125 meters in a search for ice deposits in areas of possible permanent shadow from the sun. No areas greater than 1 square kilometer were found with high radar backscatter cross sections and high circular polarization ratios, properties suggestive of the presence of ice. A number of areas smaller than 1 square kilometer were found with these properties, but optical images from spacecraft missions have shown some of these features to be in sunlight. Arecibo radar images of Sinus Iridum at latitude 47°N also showed a number of small features with similar properties. The coincidence of some of these features with the radar-facing slopes of craters and their presence in sunlit areas suggests that very rough surfaces rather than ice deposits are responsible for their unusual radar properties.</jats:p>
