Dissecting racial bias in an algorithm used to manage the health of populations

Health systems rely on commercial prediction algorithms to identify and help patients with complex health needs. We show that a widely used algorithm, typical of this industry-wide approach and affecting millions of patients, exhibits significant racial bias: At a given risk score, Black patients are considerably sicker than White patients, as evidenced by signs of uncontrolled illnesses.

Spatiotemporal expansion of primary progenitor zones in the developing human cerebellum

We present histological and molecular analyses of the developing human cerebellum from 30 days after conception to 9 months after birth.

Palmitoylation of NOD1 and NOD2 is required for bacterial sensing

The nucleotide oligomerization domain (NOD)–like receptors 1 and 2 (NOD1/2) are intracellular pattern-recognition proteins that activate immune signaling pathways in response to peptidoglycans associated with microorganisms. Recruitment to bacteria-containing endosomes and other intracellular membranes is required for NOD1/2 signaling, and NOD1/2 mutations that disrupt membrane localization are a

Structural basis for the docking of mTORC1 on the lysosomal surface

The mTORC1 (mechanistic target of rapamycin complex 1) protein kinase regulates growth in response to nutrients and growth factors. Nutrients promote its translocation to the lysosomal surface, where its Raptor subunit interacts with the Rag guanosine triphosphatase (GTPase)–Ragulator complex. Nutrients switch the heterodimeric Rag GTPases among four different nucleotide-binding states, only one

Super-elastic ferroelectric single-crystal membrane with continuous electric dipole rotation

Ferroelectrics are usually inflexible oxides that undergo brittle deformation. We synthesized freestanding single-crystalline ferroelectric barium titanate (BaTiO 3 ) membranes with a damage-free lifting-off process.

Global distribution of earthworm diversity

Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them.

We found that local species richness

High-surface-area corundum by mechanochemically induced phase transformation of boehmite

In its nanoparticulate form, corundum (α-Al 2 O 3 ) could lead to several applications. However, its production into nanoparticles (NPs) is greatly hampered by the high activation energy barrier for its formation from cubic close-packed oxides and the sporadic nature of its nucleation. We report a simple synthesis of nanometer-sized α-Al 2 O 3 (particle diameter ~13 nm, surface areas ~140 m 2 g –

Higher-fitness yeast genotypes are less robust to deleterious mutations

Natural selection drives populations toward higher fitness, but second-order selection for adaptability and mutational robustness can also influence evolution. In many microbial systems, diminishing-returns epistasis contributes to a tendency for more-fit genotypes to be less adaptable, but no analogous patterns for robustness are known. To understand how robustness varies across genotypes, we me

Microbial metabolites control the thymic development of mucosal-associated invariant T cells

How the microbiota modulate immune functions remains poorly understood. Mucosal-associated invariant T (MAIT) cells are implicated in mucosal homeostasis and absent in germ-free mice. Here, we show that commensal bacteria govern murine MAIT intrathymic development, as MAIT cells did not recirculate to the thymus. MAIT development required RibD expression in bacteria, indicating that production of

Nature Communications, Published online: 24 October 2019; doi:10.1038/s41467-019-12848-5 The activation of drugs within cellular systems may provide targeted therapies for cancer. Here, the authors make a drug delivery system that is activated within the cell and exploits XIAP expression to cleave a linker region, resulting in the self-assembly of the system and drug release within cancer cells.

Fate-mapping post-hypoxic tumor cells reveals a ROS-resistant phenotype that promotes metastasis

Nature Communications, Published online: 24 October 2019; doi:10.1038/s41467-019-12412-1 Hypoxia is known to promote tumor progression. Here, the authors evaluate hypoxic cells using a fate mapping approach and identify a distinct gene expression profile of cells exposed to intratumoral hypoxia and show that post-hypoxic tumor cells have an ROS-resistant phenotype enabling metastasis in vivo.

Chloroplastic metabolic engineering coupled with isoprenoid pool enhancement for committed taxanes biosynthesis in Nicotiana benthamiana

Nature Communications, Published online: 24 October 2019; doi:10.1038/s41467-019-12879-y Engineering Taxol pathway in microbes needs to overcome the difficulty of expressing plant P450 enzymes. Here, the authors use a compartmentalized metabolic engineering strategy to construct the taxanes production pathway in chloroplasts of Nicotiana benthamiana and realize the production of taxadience-5α-ol.

Unraveling the thermodynamic criteria for size-dependent spontaneous phase separation in soft porous crystals

Nature Communications, Published online: 24 October 2019; doi:10.1038/s41467-019-12754-w Soft porous crystals hold big promise as functional nanoporous materials due to their stimuli responsive flexibility. Here, molecular dynamics simulations reveal a new type of spatial disorder in mesoscale crystals that helps to understand the size-dependency of their phase transition behavior.

Dynamic oxygen adsorption on single-atomic Ruthenium catalyst with high performance for acidic oxygen evolution reaction

Nature Communications, Published online: 24 October 2019; doi:10.1038/s41467-019-12886-z Monitoring catalyst structural changes under working conditions is crucial for understanding how catalysts operate. Here, authors examine single-atom Ru electrocatalyst by operando synchrotron spectroscopies to identify the catalytic mechanism during the acidic oxygen evolution reaction.

Ultrabroadband 3D invisibility with fast-light cloaks

Nature Communications, Published online: 24 October 2019; doi:10.1038/s41467-019-12813-2 Three-dimensional invisibility cloaks are either limited in bandwidth or disregard the phase of the impinging wave or work only in specific directions. Here, the authors report that these restrictions can be lifted by using cloaks made of fast-light media where the wave group velocity is larger than the speed

Mindfulness meditation enhances positive effects of psilocybin

Recent years have seen a renewed interest in the clinical application of classic psychedelics in the treatment of depression and anxiety disorders. Researchers of the University of Zurich have now shown that mindfulness meditation can enhance the positive long-term effects of a single dose of psilocybin, which is found in certain mushrooms.

Martian landslides not conclusive evidence of ice

Giant ridges on the surface of landslides on Mars could have formed without ice, challenging their use by some as unequivocal evidence of past ice on the red planet, finds a new UCL-led study using state-of-the-art satellite data.

Researchers have developed a new method for upcycling abundant, seemingly low-value plastics into high-quality liquid products, such as motor oils, lubricants, detergents and even cosmetics. The discovery also improves on current recycling methods that result in cheap, low-quality plastic products.
