Bio-security for a New Era
Secrets: The Ethics of Concealment and the Ethics of Science in Synthetic Biological Research Dr. Laurie Zoloth, Center for Bioethics, Science and Society, Northwestern University Increasingly sophisticated techniques allow for increasing powerful and creative tools of biology to create new or altered forms of life. Such synthetic biology may offer unprecedented avenues for drug development, alternate energy sources, and medical therapeutics. Yet increasing unease also mounts about the possibl

Small sand volume barrier islands: Environmental processes and development risks
This Carolina Environmental Diversity Explorations "virtual field trip" explores the nature and structure of barrier islands with small sand volume — only a few small dunes and no sandy ridges between the beach and the salt marsh. Built structures on these islands are highly susceptible to damage from hurricanes. This trip provides high-resolution photographs of two such islands, Masonboro (which has not been developed) and Topsail (which has been developed). Its companion field trip, Large Sa

Viewing the Periodic Table of the Elements with X-rays
X-rays and x-ray fluorescence are not new subjects to the field of physics. Wilhelm Röntgen discovered x-rays in 1895, and in 1901 he was awarded the very first Nobel Prize in physics for this discovery. Soon after, Charles Glover Barkla discovered that each element has its own characteristic x-ray spectrum. He was awarded a Nobel Prize in physics for this discovery in 1917. Sir William Henry Bragg and his son, Sir William Lawrence Bragg, were then able to experimentally prove that the discrete
