- Probing topology by “heating”: Quantized circular dichroism in ultracold atoms
Physicists demonstrate how heating a quantum system can be used as a universal probe for exotic states of matter.
- Tunable chiral metal organic frameworks toward visible light–driven asymmetric catalysis
A general way to prepare chiral MOFs as adjustable catalysts for efficient asymmetric catalysis under visible light.
- Liquid crystalline cellulose-based nematogels
An ordered network of cellulose nanofibers infiltrated with a liquid crystal forms an electrically tunable nematogel.
- Crystallization-induced emission enhancement: A novel fluorescent Au-Ag bimetallic nanocluster with precise atomic structure
Crystallization-induced emission enhancement was achieved in metal nanoclusters for the first time.
- High-density array of ferroelectric nanodots with robust and reversibly switchable topological domain states
Robust and reversible polar topological center domains were found in BiFeO3 nanodots, which are individually controllable.
- Correlation-induced superconductivity dynamically stabilized and enhanced by laser irradiation
Laser irradiation stabilizes strong-coupling superconductivity without charge inhomogeneities that is inaccessible in equilibrium.
- Mach-Zehnder interferometry using spin- and valley-polarized quantum Hall edge states in graphene
We realize an electronic Mach-Zehnder interferometer with quantum Hall edge channels along a pn junction in graphene.
- Identifying time scales for violation/preservation of Stokes-Einstein relation in supercooled water
Various time scales characterizing transport coefficients reveal the origin of Stokes-Einstein violation in supercooled water.
- Multiple-wavelength neutron holography with pulsed neutrons
Multiple-wavelength neutron holography demonstrated a reconstruction of highly precise 3D atomic images around dopants.
- Impaired DNA replication derepresses chromatin and generates a transgenerationally inherited epigenetic memory
Inhibiting DNA replication in C. elegans embryos causes loss of repressive histone modifications and generates epialleles.
- Vomocytosis of live pathogens from macrophages is regulated by the atypical MAP kinase ERK5
ERK5 regulates nonlytic expulsion of live pathogens from phagocytes to limit dissemination of infections.
- From the surface to the seafloor: How giant larvaceans transport microplastics into the deep sea
Larvaceans can filter microplastics from the water and package them into their fecal pellets, transporting them into the deep sea.
- Adult-onset obesity is triggered by impaired mitochondrial gene expression
Reduction in an RNA binding protein impairs mitochondrial biogenesis and alters cell signaling, resulting in obesity.
- Carryover effects of larval exposure to different environmental bacteria drive adult trait variation in a mosquito vector
The adult phenotype of mosquitoes depends on the types of bacteria encountered environmentally during development.
About The Cover
August Online Cover of Science Advances shows a laborer working at a brickyard kiln in Noida, India, suffering the effects of a blistering heat wave that hovered above 45 degree Celsius (113F). This issue features a research article detailing advances in accurately calculating and understanding local and regional impacts of climate change. The research presents models that project risks from new types of extreme heat waves that are likely to hit regional hotspots , particularly across South Asia, towards the end of the 21st century. The authors identify areas where climate change, in absence of significant mitigation, is likely to severely impact human health and habitability in one of the most heavily populated regions on Earth.
