Research highlights from the current issue of Science Magazine

The Human Honeypot The possibility that international investment in protected areas would turn parks into magnets for human immigration (the "honeypot" hypothesis) and thereby reduce conservation effectiveness has been a concern of conservationists, ? [Read more] Reassessing Past Diversity Assessing past diversity of life and how it changed over time requires assembly of a database of the many individual and diverse studies of fossils. An early effort was by ? [Read more] Transistor Nanofilms For single-walled carbon nanotubes to find use in electronics, a method is needed to extract the semiconducting ones from the metallic ones and to deposit only the semiconductors into dense, ? [Read more] Test of the Double Pulsar Under general relativity and strong gravity, when massive objects orbit each other closely, their spin and orbital angular momentum should couple. This coupling leads to precession of the spin of ? [Read more] Steps in Organic Film Growth An effect often observed in the growth of inorganic thin films is that atoms are more likely to climb step edges between layers than descend. When this effect is seen, ? [Read more] Water and Ice Water derived from melting on the surface can be transferred quickly to the base of an ice sheet, lubricating the ice-ground interface and facilitating movement of the ice sheet. How ? [Read more] Toward the Tree of Life By quantifying the distribution of phylogenetically informative data across the entire eukaryotes, Sanderson (p. 121) has tackled the problem of reconstructing the complete tree of life. The available data are ? [Read more] A Mechanism for Sudden Infant Death Syndrome? Deficits in serotonin neurotransmission have been hypothesized to be involved in sudden infant death syndrome (SIDS), the leading cause of death during the first year of life. Audero et al. ?
