But studies confirm treatment can slow infections in entire communities.
- How islands shrink people
Evolutionary dwarfing affected living people on the island of Flores, and may explain the stature of the extinct hobbit.
- Staying slim during pregnancy carries a price
Japanese are shrinking as low birth weight rises; their health may be at risk as well.

Genetic variation in wild plant populations may fluctuate owing to environmental selection.
Review
Reports
- Scale-invariant magnetoresistance in a cuprate superconductor
At high magnetic fields up to 80 tesla, the resistivity of a thin-film La-based cuprate scales linearly with the field.
- A dust-enshrouded tidal disruption event with a resolved radio jet in a galaxy merger
A relativistic radio jet is seen switching on after a star is ripped apart by a black hole.
- Ultrastable laser interferometry for earthquake detection with terrestrial and submarine cables
Ultrastable lasers can be used to detect earthquakes in land-based and submarine fiber optic cables.
- Radar evidence of subglacial liquid water on Mars
Radar data from Mars Express show that there is a lake of liquid water underneath the solid ice of Mars’ southern ice cap.
- Giant polarization in super-tetragonal thin films through interphase strain
Epitaxial growth of PbTiO3/PbO composite thin films gives rise to strain and a very large spontaneous polarization.
- Quantification of drought during the collapse of the classic Maya civilization
The collapse of Lowland Classic Maya civilization during the Terminal Classic Period was triggered by a 50% reduction in rainfall.
- HAIRY MERISTEM with WUSCHEL confines CLAVATA3 expression to the outer apical meristem layers
The domain of stem cells in the Arabidopsis shoot apical meristem is founded on WUS expression but bounded by HAM expression.
- Cryo-EM structure of a mitochondrial calcium uniporter
The structure of the mitochondrial calcium uniporter reveals a tetrameric architecture and the molecular framework underlying calcium selectivity.
- Evolutionary history and adaptation of a human pygmy population of Flores Island, Indonesia
Flores Island has two independent and distinct instances of island dwarfism in hominins.

About The Cover
COVER Jets of hot plasma trace magnetic field lines that leap out into space from the Sun's surface, as shown in this colorized image from NASA's Solar Dynamics Observatory, which stares at the Sun from a vantage near Earth. New observatories will study these magnetic fields up close to understand how they heat the Sun's atmosphere and launch the solar wind. See page 441.
