512 Ultrafast Long-Range Charge Separation
in Organic Semiconductor Photovoltaic
Diodes
S. Gélinas et al.
Ultrafast spectroscopy shows electrons and

519 Unlocking the Potential of
Cation-Disordered Oxides for
Rechargeable Lithium Batteries
J. Lee et al.
Cation-disordered compounds achieve
high lithium (Li) storage capacity, with scope
for high–energy density Li battery electrodes.
522 Low Core-Mantle Boundary Temperature
Inferred from the Solidus of Pyrolite
R. Nomura et al.
High-pressure experiments suggest that
Earth’s mantle melts at lower temperatures
than previously predicted.
525 A Mechanosensory Pathway
to the Drosophila Circadian Clock
A. Simoni et al.
Flies use a mechanosensory organ to sense a
low-frequency vibration and reset the brain’s
biological clock.
529 Marine Tubeworm Metamorphosis Induced
by Arrays of Bacterial Phage Tail–Like
Structures
N. J. Shikuma et al.
Benthic marine larval development
is triggered by a bacterially expressed
structure of phage origin.

Ablation Reveals the Oocyte DNA Damage
Checkpoint Pathway
E. Bolcun-Filas et al.
Elucidation of a system that monitors DNA
damage in both meiotic and resting oocytes
in mice is shown.
536 Mating Induces Shrinking and Death in
Caenorhabditis Mothers
C. Shi and C. T. Murphy
Sperm and seminal fluid cause Caenorhabditis
mothers to die shortly after they produce
offspring.
541 Males Shorten the Life Span of C. elegans
Hermaphrodites via Secreted Compounds
T. J. Maures et al.
Male nematodes produce a soluble signal
that shortens the life span of worms of the
opposite sex.
544 Drosophila Life Span and Physiology
Are Modulated by Sexual Perception and
Reward
C. M. Gendron et al.
Female pheromones are bad for male flies.

548 Savanna Vegetation-Fire-Climate
Relationships Differ Among Continents
C. E. R. Lehmann et al.

to predict the potential global impacts on
savanna dynamics in a warming world.
552 Effector Specialization in a Lineage of the
Irish Potato Famine Pathogen
S. Dong et al.

protease inhibitors that targets its new host
plant protease.
