Shaping caustics into propagation-invariant light

Nature Communications, Published online: 17 July 2020; doi:10.1038/s41467-020-17439-3 Propagation-invariant beams have been up to now only available in a few realizations or for specific applications. Here, the authors demonstrate two methods for generating propagation-invariant beams with fully customizable intensity profiles in a comprehensive way inspired by geometrical optics.

Natural differences between pigs and dogs prevail despite similar socialization if an exciting challenge

A brainwide atlas of synapses across the mouse life span

Synapses connect neurons together to form the circuits of the brain, and their molecular composition controls innate and learned behavior. We analyzed the molecular and morphological diversity of 5 billion excitatory synapses at single-synapse resolution across the mouse brain from birth to old age. A continuum of changes alters synapse composition in all brain regions across the life span. Expan

Cancer cells deploy lipocalin-2 to collect limiting iron in leptomeningeal metastasis

The tumor microenvironment plays a critical regulatory role in cancer progression, especially in central nervous system metastases. Cancer cells within the cerebrospinal fluid (CSF)–filled leptomeninges face substantial microenvironmental challenges, including inflammation and sparse micronutrients. To investigate the mechanism by which cancer cells in these leptomeningeal metastases (LM) overcom

Ancient DNA indicates human population shifts and admixture in northern and southern China

Human genetic history in East Asia is poorly understood. To clarify population relationships, we obtained genome-wide data from 26 ancient individuals from northern and southern East Asia spanning 9500 to 300 years ago. Genetic differentiation in this region was higher in the past than the present, which reflects a major episode of admixture involving northern East Asian ancestry spreading across

Second critical point in two realistic models of water

The hypothesis that water has a second critical point at deeply supercooled conditions was formulated to provide a thermodynamically consistent interpretation of numerous experimental observations.

Here, we use histogram reweighting and large-system scatterin

Giant piezoelectricity in oxide thin films with nanopillar structure

High-performance piezoelectric materials are critical components for electromechanical sensors and actuators.

Boron-enabled geometric isomerization of alkenes via selective energy-transfer catalysis

Isomerization-based strategies to enable the stereodivergent construction of complex polyenes from geometrically defined alkene linchpins remain conspicuously underdeveloped.

N-Aryl-linked spirocyclic polymers for membrane separations of complex hydrocarbon mixtures

The fractionation of crude-oil mixtures through distillation is a large-scale, energy-intensive process. Membrane materials can avoid phase changes in such mixtures and thereby reduce the energy intensity of these thermal separations.

Here, we use a climate-dependent epidemic model to simulate the SARS-CoV-2 pandemic by
