In Brief


A roundup of weekly science policy and related news.



In Depth


Aids Conference

Remission is seen as a more realistic goal.


Climate Change

Studies suggest that atoll islands will rise in step with a rising sea.


Immunology

Stanford researchers unable to replicate findings linking immune response to sleep disorder.


Public Health

Lacking vital medical supplies, doctors struggle to treat resurgent diseases.


Europe

Green groups criticize current adviser—and her office.


Italy

New industry-sponsored study rules out any link between Italian earthquakes and oil production.



Feature


Europe's Rosetta spacecraft is about to orbit and then land on one of the solar system's most mysterious objects.


The most daring moment of the Rosetta mission will come when mission leaders plan to drop the Philae lander to the surface of comet 67P/Churyumov-Gerasimenko.


More capable than once thought, the cellular structure known as the nucleolus may be a target for treating diseases.

Perspectives


Evolution

Sustained size reduction was essential for the origin of birds and avian flight [Also see Report by Lee et al.]


Quantum Information

Diamond-based quantum teleportation works every time [Also see Research Article by Pfaff et al.]


Evolution

DNA damage in ancient genomes may provide insight into past regulatory changes in humans and other species


Neuroscience

Persistent pain changes a neural circuit and reduces willingness to work for food [Also see Research Article by Schwartz et al.]


Astronomy

Pulsations from young stars provide a new chronometer for stellar evolution [Also see Report by Zwintz et al.]


Development

A Turing network controls the periodic pattern of fingers and toes during development [Also see Report by Raspopovic et al.]


Immunology

Cellular signals during helminth infections can skew the immune response to favor viral spreading [Also see Reports by Reese et al. and Osborne et al.]



Reviews



Research Articles


Tumor genomes are peppered with mobile repeat sequences that carry along adjacent DNA when they insert into new genomic sites.


A quantum state can now be teleported unconditionally between diamond defects 3 meters apart. [Also see Perspective by Atatüre and Morton]


The effort mice are willing to put into obtaining a reward is decreased in inflammatory and neuropathic models of pain. [Also see Perspective by Fields]



Reports


Optimizing the growth conditions of the perovskite layer and interlayer carrier transport boosts solar cell efficiency.


Synergy at a metal-oxide interface generates highly active catalysts for carbon dioxide hydrogenation to methanol.


Pulsation measurements of stars not yet undergoing nuclear burning confirm a predicted correlation with evolutionary status. [Also see Perspective by Stahler and Palla]


Three classical novae exhibit unexpected high-energy particle acceleration and may represent the norm for that object class.


Birth and death records of notable individuals reveal a picture of Western cultural history over two millennia.


Birds evolved from their dinosaurian ancestors through a period characterized by sustained and repeated decreases in size. [Also see Perspective by Benton]


Modeling and experiments reveal how limb digits are patterned by three components. [Also see Perspective by Zuniga and Zeller]
