- New Products
A weekly roundup of information on newly offered instrumentation, apparatus, and laboratory materials of potential interest to researchers.
In Brief
In Depth
- Refugee crisis brings new health challenges
Imported pathogens are a much bigger threat to migrants than they are to Europeans.
- How sign languages evolve
Young sign languages develop in predictable ways, offering clues to the evolution of linguistic complexity.
- No deadline, fewer requests
National Science Foundation trial spurs drop in proposals.
- Templeton grant funds evolution rethink
$8.7 million to test controversial ideas that go beyond genes and natural selection.
- The tiniest titan
Fossil of a baby titanosaur shows that even the youngest of these giant dinosaurs were ready to take on the world.
- When the payoff for academics drops, commercialization suffers
A change in Norway's laws leads to sharp drop in the number of patents and startups by academics.
- Cadaver study challenges brain stimulation methods
Unusual test of transcranial stimulation shows that little electrical current penetrates the skull.
Feature
- Malaria wars
Can malaria be eliminated from the Mekong region before multiple-drug resistance makes it untreatable?
- Skirmishing over the scope of the threat
As malaria experts chart their battle plans, they are looking to the past for clues.
- Rubber workers on the front lines
A new effort to reach migrant workers could make or break plans for malaria elimination.
- The unlikely diplomat
Myaing Myaing Nyunt fled Myanmar in 1988; now she is back, forging alliances against malaria.
- The village recruiter
In tests of a controversial strategy, advance liaison to often-skeptical villagers is crucial.

An ultrafast optics approach is used to generate and control ultrashort pulses of electrons.
Review
Reports

A chiral copper catalyst alkylates a class of compounds of interest in medicinal chemistry research.
- Atomic-scale control of graphene magnetism by using hydrogen atoms
Scanning tunneling microscopy shows that a hydrogen atom deposited on graphene makes the complementary sublattice magnetic.
- Bell correlations in a Bose-Einstein condensate
Strong quantum correlations are detected among the spins of 480 rubidium atoms in a condensed state.
- Continental arc volcanism as the principal driver of icehouse-greenhouse variability
A global analysis of detrital zircons suggests that volcanism is the primary driver of very long-term climate oscillations.

Enzymes attached to photoexcited semiconductor nanorods turn nitrogen into ammonia.
- Precocity in a tiny titanosaur from the Cretaceous of Madagascar
Tiny giant suggests that largest dinosaurs were precocial at birth.
- RNA-binding proteins ZFP36L1 and ZFP36L2 promote cell quiescence
RNA-binding proteins enforce quiescence on developing lymphocytes by suppressing cell cycle progression.
- Hobit and Blimp1 instruct a universal transcriptional program of tissue residency in lymphocytes
Tissue-dwelling lymphocyte populations share a common transcriptional signature.

How age and the innate immune system affect influenza immunity is discussed.
- The 3.8 Å resolution cryo-EM structure of Zika virus
The structure of mature Zika virus is similar to other flaviviruses, except in the region of a potential cell attachment site.
- A beak size locus in Darwin’s finches facilitated character displacement during a drought
A genome-wide analysis in finches identifies loci associated with parallel size variation in the Galápagos.
- Health and population effects of rare gene knockouts in adult humans with related parents

About The Cover
COVER Migrant workers such as this man, one of nearly 50 workers employed at a farm in Palin, Cambodia, near the border with Thailand, are at especially high risk of contracting malaria. Reaching them is one of many challenges facing an ambitious new effort to wipe out all malaria from the Greater Mekong subregion by 2030. See page 398.
