May 26, 2000 -- Vol. 4 Number 21

-----------------------------------------------

The trick is to listen to what the experiments
tell you -- and to not be fooled by the myths
of authorities.
-- Constantine Spyropoulos (1928-1984)

-----------------------------------------------

Contents of This Issue:

1. History of Science:
On the History of Genomics
--------------------------
One of the greatest scientific achievements of the modern epoch
has been the elucidation by biologists of the mechanisms of
heredity, and it is apparent that the applications of this
knowledge will in the future dramatically change the way the
human species lives and dies.

2. Neurobiology:
Synaptic Assembly Without Neurotransmitter Secretion
----------------------------------------------------
Engineered deletion of a single protein in mice leads to a
complete loss of neurotransmitter secretion from synaptic
vesicles throughout development, but this deletion does not
prevent normal brain assembly. (Includes related background
material.)

3. Developmental Biology:
Cloned Calves Produced from Adult Cells After Long-Term Culture
---------------------------------------------------------------
Adult somatic cells remain totipotent for cloning after long-term
culture, suggesting the feasibility of targeted genetic
manipulations using cultured somatic cells before cloning to
produce genetically engineered cloned animals. (Includes related
background material.)

4. Biotechnology:
DNA Microarrays in Medicine
---------------------------
Detailed molecular pictures provided by genomic expression
analysis will revolutionize molecular medicine just as high-
resolution radiographic imaging methods have revolutionized
diagnosis and treatment at the gross anatomic level.

5. Theoretical Physics:
On Interpretations of Quantum Theory
------------------------------------
Two theoretical physicists argue that quantum theory is a fully
consistent theory and that it needs no "interpretation" to make
it a useful guide to the phenomena around us. (Includes related
background material.)

6. Planetary Science:
Fullerenes and Caged Noble Gases in Meteorites
----------------------------------------------
High-mass naturally occurring fullerenes encapsulating noble
gases have been discovered in the Allende and Murchison
meteorites and in sediment samples from the 65 million-year-old
Cretaceous/Tertiary boundary layer.

In Focus: On the Heisenberg Uncertainty Relation
