SHARKSKIN SUIT— Speedo has
developed a new swimsuit it says will
shave 3% off swimmer’s race times.
The key is in the fabric, which mimics
a shark’s skin. Speedo spokesman
Chris Woods said, “The size and
shape of a shark means it should be
dead in the water, but nature has
found a way round that and it is in
fact one of the fastest things in the
sea. That is due to the way its skin has
evolved over the past 400 million
years — we have mimicked that.”
Speedo credits the shark’s speed to
“dermal denticles” or ridges on the
shark’s skin that allow water to glide
across the surface with little resistance.
The suit, which was developed
in conjunction with the Natural
History Museum and Olympic
swimmers, will be cut as a second
skin, so that only the head, hands,
and feet are uncovered. Though the
difference in speed is minimal —
7.5% on the glide and 3% overall —
that may be enough. In 31 of 32 swim
finals in the last Olympics, there was
less than a 3% difference between the
first and sixth place finisher.
BACK IN WITH INNER EAR OUT— Inner
ear barotrauma, caused by a hemorrhage
in the inner ear, a tear of the
labyrinthine membrane, or a fistula,
have historically led to a recommendation
that victims stop diving. Now,
several researchers, after studying the
injury, say that “although the older
literature clearly suggests otherwise, we
believe that scuba divers who completely
recover from inner (or middle)
ear barotrauma may return to diving as
long as they exercise caution and care.”

SANCTUARY — Last month another
Caribbean reef was given protected
status: the Minister of Fisheries in
Belize and fishermen and stakeholders
of Glover’s Reef signed an agreement
essentially declaring the reef a nofishing
zone. (One family that lives on
the reef will be allowed to continue
subsistence fishing.) The manager of
the reserve promised to immediately
“mark the zones ... so that when we
catch fishermen inside the zone, there
is no argument whatsoever.” Manta
Resort is located on Glover's.
