- Electrochemical electron beam lithography: Write, read, and erase metallic nanocrystals on demand
We develop an electrochemistry- and radiolysis-based patterning technique for site-specific deposition and dissolution of metallic nanocrystals.
- Multiplexed gene control reveals rapid mRNA turnover
Researchers develop a new method to show that messenger RNA molecules live much shorter lives in the cell than previously thought.
- Distinct distributed patterns of neural activity are associated with two languages in the bilingual brain
This fMRI study using MVPA reveals separated neural patterns for the first and second languages.
- Inactivation of thermogenic UCP1 as a historical contingency in multiple placental mammal clades
Inactivation of uncoupling protein 1 is linked to shifts in metabolic rate, body size, and species richness of eight mammalian lineages.
- Unsustainable development pathways caused by tropical deforestation
Deforestation causes unsustainable development in tropical countries, compromising the well-being of future generations.
- Response to Lieberman on “Monkey vocal tracts are speech-ready”
Macaques do have a speech-ready vocal tract, but lack a speech-ready brain to control it.
- Solving protein structures using short-distance cross-linking constraints as a guide for discrete molecular dynamics simulations
Short-distance cross-linking constraints combined with discrete molecular dynamics enable rapid prediction of protein structures.
- Detection of a dynamic topography signal in last interglacial sea-level records
Topographic changes due to mantle convection affected the elevation of last interglacial sea-level records across the globe.
- Comment on “Monkey vocal tracts are speech-ready”
Charles Darwin was correct to wonder why humans have tongues and airways that can make us more susceptible to choking on food.
- A fourth Denisovan individual
DNA retrieved from a tooth discovered deep in Denisova Cave allows us to assign it to the Denisovans, a group of archaic hominins.

Extracellular polymeric substances play important roles in microbial extracellular electron transfer processes.
- A tail of two voltages: Proteomic comparison of the three electric organs of the electric eel
Proteomic differences among three electric organs of electric eel reflect trade-offs between generating weak and strong voltages.
- Population genomics of picophytoplankton unveils novel chromosome hypervariability
Phytoplanktonic eukaryotes form huge panmictic populations and have evolved original hypervariability mechanisms to resist viral attack.
About The Cover
ONLINE COVER While human machine-interfaces have improved in recent years, making truly wearable versions that perform multiple functions—while enabling highly efficient communication between humans and machines—has remained challenging. Sim et al. develop an ultra-thin electronic device that can directly guide a robot hand with signals collected from the user’s muscles, enabling the human to feel what the robot experiences. The design consists of an easy-to-manufacture nanomembrane made from indium zinc oxide that is almost imperceptible when worn and maintains its function when human skin is stretched or compressed. Sensors made from this material could be designed to monitor UV exposure (to mitigate skin disease risk) or to detect skin temperature (to provide early medical warnings), while still functioning well under strain.
