Progress toward synthetic cells.

The complexity of even the simplest known life forms makes efforts to synthesize living cells from inanimate components seem like a daunting task. However, recent progress toward the creation of synthetic cells, ranging from simple protocells to artificial cells approaching the complexity of bacteria, suggests that the synthesis of life is now a realistic goal. Protocell research, fueled by adv...

Progress Toward Optimal

Over the last several years, a variety of multipoint virtual circuit switching systems have been proposed for use in Asynchronous Transfer Mode (ATM) networks. The inherent exibility of ATM networking and the desire to apply this technology to a wide range of diierent applications makes it impractical to rely on statistical traac models when engineering a system. This motivates a renewed intere...

Progress toward an HIV vaccine.

The development of an HIV vaccine is proving to be an unprecedented challenge. The difficulty in creating this vaccine arises from the enormous genetic variation of the virus and the unusual importance of cytotoxic T lymphocytes (CTL) in controlling its spread. Whereas traditional vaccine strategies are unlikely to confer safe and effective HIV protection, novel strategies for eliciting CTL hav...

Progress in Dialectometry: Toward Explanation

Dialectometric techniques analyze linguistic variation quantitatively, allowing one to aggregate over what are frequently rebarbative geographic patterns of individual linguistic variants, such as which word is used for a particular concept in a language area, or which sounds are used in particular words. This leads to general formulations of the relation between linguistic variation and explan...
