-------------------------- WEEKLY REVIEW ---------------------------
** SCIENTISTS DISCOVER DISTINCTIVE DEEP-SEA SQUID
The depths of the ocean remain largely unexplored, so it's hardly
surprising that new creatures continue to reveal themselves to
scientists and their submersibles. A new report describes one such
novel animal, a large deep-sea squid sighted eight times in the last
few years at sites around the globe.

** THE CELLULAR UNDERPINNINGS OF THE FRENCH PARADOX
About a decade ago, the discovery of the French paradox--that people
living in France have a lower incidence of heart disease than do their
British counterparts, despite a comparable intake of dietary fat--
touched off the ongoing debate over the health benefits of alcohol.
New research suggests that components specific to red wine do indeed
provide protection against coronary artery disease.

** PHYSICISTS PROBE PROTON'S SPIN PROPERTIES
When it comes to a proton's spin, the whole is more than the sum of
its quarks. Each proton contains three quarks, the spins of which
can only account for about 20 percent of the proton's spin. But new
experimentsusing Brookhaven National Laboratory's Relativistic
Heavy Ion Collider (RHIC) may help untangle the problem of the
proton's missing spin by further investigating the properties of
gluons, the particles that hold quarks together and carry the
so-called strong force.

~~~~~~~~~~~~~~~~~~~~ BOOKSTORE ~~~~~~~~~~~~~~~~~~~

EYE OF THE WHALE: EPIC PASSAGE FROM BAJA TO SIBERIA
by Dick Russell.

The whale is Eschrichtius robustus, the gray whale of the Eastern
Pacific, which makes "a twice-annual migration that must be regarded
as one of the most spectacular achievements on the planet." Swimming
close to the shore, some 26,000 grays travel from breeding areas in
the central Baja California region of Mexico to Arctic feeding
grounds near the Bering Strait and back--a minimum of 5,000 miles
each way. Environmental journalist Russell writes sensitively about
the past, present and uncertain future of these remarkable animals.

** TEMPERATURE TUNES A TINY LASER'S COLOR
The telltale signature of most lasers used in everyday applications--
from bar-code scanners to pen-size pointers--is a bright red glow.
The color is determined by the light's wavelength, and most lasers
emit at only one wavelength. A new describes a light source measuring
only tens of millimeters across that changes color according to
temperature.

** ATHLETES CAN TRAIN TO AVOID CHOKING UNDER PRESSURE
Some sports fans might argue that this year's World Series went to a
nail-biting seventh game because Arizona Diamondbacks relief pitcher
Byung-Hyun Kim choked, twice. The phenomenon of choking--performing
worse than expected under pressure--has long plagued professional
athletes and performers, but its cause was unclear. Do performers
choke because they pay too much attention to their actions or because
they get distracted and pay too little attention? A new report
suggests that it is overattending to a well-learned skill that
causes choking.
