New protests, old paradigms.

New viruses shake old paradigms.

Kaposi sarcoma-associated herpesvirus (KSHV) can establish latent infection in host cells. The latently infected cells can survive and proliferate with a few viral genes expressed. However, in some Kaposi sarcoma cells, KSHV undergoes a productive life cycle and causes cell lysis. A new study (see the related article beginning on page 124) demonstrates that, after KSHV infection or introduction...

Crustacean Hyperglycemic Hormone Family: Old Paradigms and New Perspectives1

SYNOPSIS. I present an overview of recent research on the isolation and characterization of members of the crustacean hyperglycemic hormone (CHH) neuropeptide family. Members of this arthropod-specific family include CHH, molt-inhibiting hormone (MIH), vitellogenesis-inhibiting hormone (VIH), and mandibular organ-inhibiting hormone (MOIH). There are two subfamilies of this neuropeptide group, b...

Old and New: Changing Paradigms in Arid Lands Water Management

Water management paradigms and practices have evolved markedly from the post-World War II years to the twenty-first century. Changes have been particularly urgent and visible in water-limited arid lands. Notable trends include movement from an emphasis on technological, supply-side solutions toward sociological, demand-side management; from rigid top-down state control toward decentralized mana...

Evolving Tale of TCPs: New Paradigms and Old Lacunae

Teosinte Branched1/Cycloidea/Proliferating cell factors (TCP) genes are key mediators of genetic innovations underlying morphological novelties, stress adaptation, and evolution of immune response in plants. They have a remarkable ability to integrate and translate diverse endogenous, and environmental signals with high fidelity. Compilation of studies, aimed at elucidating the mechanism of TCP...
