---THIS WEEK'S HIGHLIGHTS:

--Biological Sciences
-The CatSper channel mediates progesterone-induced Ca2+ influx in
human sperm
The finding that the female steroid hormone progesterone activates
the CatSper calcium channel in the sperm flagellum at conception could
lead to the development of new classes of non-hormonal contraceptives.

--Physical Sciences
-Single-spin addressing in an atomic Mott Insulator
A new technique achieves coherent spin-manipulation in a strongly
correlated quantum system consisting of an optical lattice of ultracold
atoms, making it possible to control the spins of individual atoms for
the first time,

--Earth & Environmental Sciences
-The role of crustal quartz in controlling Cordilleran deformation
A long-standing mystery in the field of plate tectonics can be summarized
with the question, why are mountain ranges where they are? Anthony Lowry
and Marta Perez-Gussinye show that the local abundance of crustal quartz,
the weakest mineral in continental rocks, may be a major factor.

WORLD VIEW
** Cash alone will not slow forest carbon emissions
To succeed, the REDD initiative needs a dose of 'GREEN' to restore
degraded forests and help boost economic development,
argues Andy White.

FEATURES
** Virology: Fighting for a cause
When Judy Mikovits found links between chronic fatigue syndrome and
a virus, the world took notice. Now, she's caught between the
patients who believe her work and the researchers who don't.

** Physics: Unification + 150
In 1861, James Clerk Maxwell unified electricity, magnetism and light.
Experiments under way today could inch physicists closer to combining
everything else.
http://links.ealert.nature.com/ctt?kn=32&m=36390638&r=MjA1NzcwMjE4MQS2&b=2&j=OTY4MDUxMTMS1&mt=1&rt=0

COMMENT
** The laird of physics
James Clerk Maxwell's 1861 work on electromagnetism, which unified
scientific fields, was driven as much by technology as by abstract
theorizing, argues Simon Schaffer.
http://links.ealert.nature.com/ctt?kn=100&m=36390638&r=MjA1NzcwMjE4MQS2&b=2&j=OTY4MDUxMTMS1&mt=1&rt=0

** To invisibility and beyond
Combining Maxwell's equations with Einstein's general relativity
promises perfect images and cloaking devices, explains Ulf Leonhardt.

Nature Special: Maxwell's Equation

150 years ago this month a 30 year old James Clerk Maxwell wrote
down the equations that laid the foundations for modern physics.
Four pieces in this week's Nature discuss the origin and legacies
of Maxwell's insight.
