Predicting new molecular targets for known drugs pp175-181
Drugs that are chemically quite similar often bind to biologically 
diverse protein targets, and it is unclear how selective many of 
these compounds are. Because many drug-target combinations exist, 
it would be useful to explore possible interactions computationally. 
Here, 3,665 drugs are tested against hundreds of targets; chemical 
similarities between drugs and ligand sets are found to predict 
thousands of unanticipated associations.

Direct inhibition of the NOTCH transcription factor complex pp182-188
It is notoriously difficult to target transcription factors with 
aberrant activity in cancer. Inappropriate activation of the NOTCH 
complex of transcription factors is directly implicated in the 
pathogenesis of several disease states, including T-cell acute 
lymphoblastic leukaemia. The design of synthetic, cell-permeable, 
stabilized [alpha]-helical peptides that disrupt protein-protein 
interactions in NOTCH is now described.

Enhanced lithium depletion in Sun-like stars with orbiting planets 
pp189-191
Although a large range of lithium (Li) abundances is observed in 
solar-type stars, this range has proved theoretically difficult to 
understand. An earlier suggestion that Li is more depleted in stars 
with planets was weakened by the lack of a proper comparison sample 
of stars without detected planets. Here, Li abundances are reported 
for an unbiased sample of solar-analogue stars with and without 
detected planets. It is found that about 50% of the solar analogues 
without detected planets have on average ten times more Li that those 
with planets.

Fractional quantum Hall effect and insulating phase of Dirac electrons 
in graphene pp192-195
The fractional quantum Hall effect (FQHE) is the quintessential 
collective quantum behaviour of charge carriers confined to two 
dimensions but it has not yet been observed in graphene, a material 
distinguished by the charge carriers' two-dimensional and relativistic 
character. Here, and in an accompanying paper, the FQHE is observed 
in graphene through the use of devices containing suspended graphene 
sheets; the results of these two papers open a door to the further 
elucidation of the complex physical properties of graphene.

dimensions but it has not yet been observed in graphene, a material 
distinguished by the charge carriers' two-dimensional and 
relativistic character. Here, and in an accompanying paper, the FQHE 
is observed in graphene through the use of devices containing 
suspended graphene sheets; the results of these two papers open a 
door to the further elucidation of the complex physical properties 
of graphene.

Mapping GFP structure evolution during proton transfer with femtosecond 
Raman spectroscopy pp200-204
Tracing the transient atomic motions that lie at the heart of chemical 
reactions requires high-resolution structural information on the 
timescale of molecular vibrations. Femtosecond stimulated Raman 
spectroscopy is now shown to provide sufficiently detailed and 
time-resolved vibrational spectra of the electronically excited 
chromophore of green fluorescent protein to reveal skeletal motions 
involved in the proton transfer that produces the fluorescent form of 
the protein.

Oxygen and hydrogen isotope evidence for a temperate climate 3.42 
billion years ago pp205-208
The study of stable oxygen isotope ratios ([delta]18O) of Precambrian 
cherts suggests that ocean temperatures during the Archaean era 
(about 3.5 billion years ago) were between 55 [deg]C and 85 [deg]C, 
but uncertainty about the [delta]18O of the primitive ocean has led to 
considerable debate regarding this conclusion. Here, a combined analysis 
of oxygen and hydrogen istopes sampled from 3.42-billion-year-old Buck 
Reef Chert rocks in South Africa indicates that the ancient ocean was 
much cooler than previously thought.

Permeability of asthenospheric mantle and melt extraction rates at 
mid-ocean ridges pp209-212
The timescale for segregation and transport of basaltic melts, which 
are ultimately responsible for formation of the Earth's crust, is 
critically dependent on the permeability of the partly molten 
asthenospheric mantle, yet this permeability is known mainly from 
semi-empirical and analogue models. A high-pressure, high-temperature 
centrifuge is now used to measure the rate of basalt melt flow in 
olivine aggregates; the resulting permeabilities are one to two orders 
of magnitude larger than predicted by current parameterizations.

Human-specific transcriptional regulation of CNS development genes by 
FOXP2 pp213-217
The transcription factor FOXP2 is the only gene implicated in human 
speech, and yet it differs very little from the chimpanzee orthologue. 
Here, the two amino acids specific to humans are shown to alter FOXP2 
function in vitro by conferring differential transcriptional regulation, 
and these observations are extended in vivo to human and chimpanzee 
brain. Together, these data identify transcriptional targets that may 
serve critical functions in language development.

Bidirectional plasticity in fast-spiking GABA circuits by visual 
experience pp218-221
The contribution of individual circuit elements to experience-dependent 
synaptic plasticity in the brain remains unknown. An intracellular 
analysis of the changes that occur when an eye is deprived of vision 
in early life now reveals a counterintuitive initial shift towards the 
occluded eye followed by a late preference for the open eye. These 
results, combined with intracellular pharmacology, suggest that 
inhibitory neurons have a major role in shaping experience-dependent 
plasticity in the developing visual cortex.

Human DAZL, DAZ and BOULE genes modulate primordial germ-cell and 
haploid gamete formation pp222-225
Defects in human germ-cell (oocyte and sperm) development are the 
leading cause of infertility in men and women. A germ-cell reporter 
is now used to quantify and isolate primordial germ cells derived 
from both male and female human embryonic stem cells. Human DAZL 
is observed to function in primordial germ-cell formation, whereas 
the closely related genes DAZ and BOULE promote later stages of 
meiosis and development of gametes.

Uptake through glycoprotein 2 of FimH+ bacteria by M cells initiates 
mucosal immune response pp226-230
To evoke the mucosal immune system, which forms the largest part of 
the entire immune system, antigens on the mucosal surface must be 
transported across the epithelial barrier. The molecular mechanisms 
promoting this antigen uptake, called antigen transcytosis and 
mediated by specialized epithelial M cells, remain largely unknown. 
Here, glycoprotein 2, specifically expressed by M cells, is reported 
to serve as a transcytotic receptor for mucosal antigens.

Cohesin acetylation speeds the replication fork pp231-234
Cohesin inhibits the transcriptional machinery's interaction with 
and movement along chromatin, but does not prevent replication 
forks from duplicating the genome in S phase. Using single-molecule 
analysis, a replication complex is now found to affect acetylation 
of a subunit of cohesin, and this acetylation appears to be a central 
determinant of fork processivity. Loss of this regulatory mechanism 
leads to the spontaneous accrual of DNA damage.
