This decline in mortgage interest rates mirrored a fall in the 10-year Treasury bond yield (the interest rate on the bond), as shown in the left panel of Figure 1. In fact—as shown in the right panel of Figure 1—mortgage interest rates almost always mirror the yields on long-term Treasury bonds because they respond to the same forces. What factors drove the sharp declines in yields on 10-year T...

base and precious metals associated with porphyry, epithermal and acid sulphate or high-snlphidation hydrothermal systems (Panteleyev, 1992; Panteleyev and Koyanagi, 1993, 1994). The majority of these systems are associated with the Early to Middle Jurassic Island Plutonic Suite and Early Jurassic B O M ~ Group rocks. The regional mapping component of this study focused primarily on potential t...

Stomatal characteristics affecting gas exchange were compared in two sweet corn hybrids (var. Bonanza and Monarch Advance) which differ in foliar ozone sensitivity. No significant differences were observed in stomatal frequencies, guard cell lengths, or conductances to water vapor diffusion.When plant water status was compared, leaf-water potentials for the ozone-resistant cultivar, Bonanza, we...

It's a translation bonanza. This month's responses to our Cell Systems Call (Cell Systems 1, 307) include four that illuminate principles governing the production of proteins from mRNA.
