DARPA at 50
This week's Nature explores the past, present and future of
DARPA, the Defense Advanced Research Projects Agency. Over the
past 50 years the agency has altered warfare and civilian life,
with spinouts such as the Internet, unmanned aircraft, GPS
systems and much more. Former director Charles Herzfeld recounts
what made DARPA such a success in an Essay. In a News Feature,
Sharon Weinberger explores whether DARPA is still relevant today,
and how other agencies are hoping to ape its famously nimble
approach. For more information on DARPA, listen to this week's
Nature Podcast.

Observations and modelling of two plumes in Jupiter's atmosphere that

Emergent reduction of electronic state dimensionality in dense ordered
Li-Be alloys pp445-448
A computational study identifies pressure-induced reactivity between
the two lightest metals, lithium and beryllium. Although normally not
even miscible, they form a number of ordered alloy compounds stable at
high pressures. Intriguingly, quasi-two-dimensional electronic states
emerge within the three-dimensional crystal environment of one of the
alloys. This feature appears as the high pressure 'squeezes' electrons
away from the lithium atoms and into layers of almost ideal
free-electron like states that are close to the beryllium atoms.

Anthropogenically enhanced fluxes of water and carbon from the
Mississippi River pp449-452
A high temporal resolution, 100-year data set from the Mississippi
River is coupled with sub-watershed and precipitation data to reveal
that a ~40 percent increase in flux of bicarbonate that has occurred
over the last 50 years is clearly anthropogenically driven. This is
caused by an increase in discharge from agricultural watersheds not
balanced by a rise in precipitation. It is suggested that land use
change and management are arguably more important than changes in
climate and carbon dioxide fertilization.

The basis of regulation of proliferation of pluripotent embryonic stem

tissue specific stem cell types via a mechanism that involves cell

responses.

Dscam and Sidekick proteins direct lamina-specific synaptic
connections in vertebrate retina pp465-469
The computing power of the brain depends on its components, nerve
cells, being wired to each other in very specific patterns. Some of
the molecules involved in this specificity have been identified, and
it is demonstrated that nerve cells miss-wire when these molecules are
missing or, conversely, when they are present in the wrong place.

Neurite arborization and mosaic spacing in the mouse retina require
DSCAM pp470-474
In establishing circuits in the retina, retinal neurons form complex
patterns depending on repulsion or attraction to their own processes,
and to the cell bodies and processes of other neurons. The first cell
surface adhesive protein that mediates this cell spacing in the
mammalian retinal is described. This paper also identifies a
spontaneous mutation in mice that creates a loss of function allele of
Dscam, which in Drosophila mediates dendrite arborization and axon
tiling, and finds the mutants eyes had disorganized retinas with
faulty cell spacing.

Coordinated regulation of Arabidopsisthaliana development by light and
gibberellins p475-479
Light and gibberellins (GA) regulate multiple aspects of plant
development, and this paper is one of two studies that provide
molecular insights into the connection between these pathways. Without
GA, DELLA proteins (GA-signalling repressors) interact with PIFs
(phytochrome interacting proteins) and inhibit their binding to gene
promoters. GA triggers degradation of DELLA proteins, thereby allowing
PIFs to bind to their target promoters and regulate gene expression.
These results reveal a signalling cascade that contributes to
coordinated plant growth regulation by light and gibberellins.

Distinct roles of the FliI ATPase and proton motive force in bacterial
flagellar protein export pp485-488
Bacterial flagella contain a secretion apparatus that is related to
the type III secretion system used by many pathogens to transfer
effector proteins into host cells. It has been thought that the
ATPase, FliL provides the energy for transport. This is one of two
papers that argue against this widely held view and show that
flagellar secretion can occur even in the absence of the ATPase and is
instead driven by the proton motive force.

Energy source of flagellar type III secretion pp489-492
Bacterial flagella contain a secretion apparatus that is related to
the type III secretion system used by many pathogens to transfer
effector proteins into host cells. It has been thought that the
ATPase, FliL provides the energy for transport. This is one of two
papers that argue against this widely held view and show that
flagellar secretion can occur even in the absence of the ATPase and
is instead driven by the proton motive force.
