- Spatial and temporal seismic velocity changes on Kyushu Island during the 2016 Kumamoto earthquake
We mapped temporal seismic velocity variations during the Kumamoto earthquake due to fault rupture and a volcanic eruption.
- Ultrafast dynamics of vibrational symmetry breaking in a charge-ordered nickelate
Terahertz pulses reveal the multiscale dynamics of the crystal symmetry upon melting and formation of atomic-scale stripes.
- Synthetic “smart gel” provides glucose-responsive insulin delivery in diabetic mice
A synthetic polymer gel–based insulin delivery device provides an artificial pancreas–like function in healthy and diabetic mice.
- Biomass recycling and Earth’s early phosphorus cycle
The scarcity of oxidants in the ancient oceans may have inhibited phosphorus recycling, stifling the growth of the biosphere.
- The prevalence of kilometer-scale heterogeneity in the source region of MORB upper mantle
Observed Nd-Hf systematics in natural samples can be reproduced by melting a mantle with heterogeneities on kilometer scale.
- Artificially lit surface of Earth at night increasing in radiance and extent
Earth’s artificially lit area is expanding at 2.2% per year, with existing lit areas brightening by 2.2% per year.
- Seismic potential of weak, near-surface faults revealed at plate tectonic slip rates
Experimental shearing at plate rate speeds reveals slow slip events and earthquake potential on weak, shallow faults.
- Climate change and water management in the biblical city of Dan
Past climate shifts in water-stressed areas show that stagnant water could be a health threat in the context of global change.
- Networks of global bird invasion altered by regional trade ban
European Union’s ban on trade in wild-caught birds both reduces and redistributes bird invasion risk globally.
- Extreme enrichment in atmospheric 15N15N
Upper-atmospheric chemistry and biological N2 cycling engage in a planetary-scale tug-of-war seen in 15N15N of air.
- Strained hybrid perovskite thin films and their impact on the intrinsic stability of perovskite solar cells
Strain discovered in hybrid perovskite films made by existing methods affects perovskite solar cells’ intrinsic stability.
- Tailor-made temperature-dependent thermal conductivity via interparticle constriction
Mesostructuring and geometric constriction control the temperature-dependent thermal transport properties in granular matter.
- Two-dimensional limit of crystalline order in perovskite membrane films
A topological crystalline to amorphous phase transition predicted in 2D systems is observed in freestanding oxide films.
- Reactive oxygen species leave a damage trail that reveals water channels in Photosystem II
This study illuminates the locations of water channels within Photosystem II, a large membrane protein complex.
