A theoretical explanation for an enhanced thermal Hall response in high-temperature superconductors

A few months ago, a team of researchers led by Louis Taillefer at the University of Sherbrooke measured the thermal Hall conductivity in several compounds of copper, oxygen and other elements that are also high-temperature superconductors known as 'cuprates.' In physics, the thermal Hall effect describes heat flow in a direction transverse to a temperature gradient.

Coulomb-driven single defect engineering for scalable qubits and spin sensors in diamond

Nature Communications, Published online: 31 October 2019; doi:10.1038/s41467-019-12556-0 Nitrogen vacancy centres occur naturally in diamond and have potential uses in quantum computing but many applications require scalable, accurate fabrication methods. Here the authors demonstrate that tuning the doping modifies the dynamics of centre formation, increasing yields and coherence times.

Self-renewing endometrial epithelial organoids of the human uterus [Cell Biology]

The human endometrium is essential in providing the site for implantation and maintaining the growth and survival of the conceptus. An unreceptive endometrium and disrupted maternal−conceptus interactions can cause infertility due to pregnancy loss or later pregnancy complications. Despite this, the role of uterine glands in first trimester human pregnancy…

Single-nucleotide control of tRNA folding cooperativity under near-cellular conditions [Biochemistry]

RNA folding is often studied by renaturing full-length RNA in vitro and tracking folding transitions. However, the intracellular transcript folds as it emerges from the RNA polymerase. Here, we investigate the folding pathways and stability of numerous late-transcriptional intermediates of yeast and Escherichia coli transfer RNAs (tRNAs). Transfer RNA is…

Timing and specificity of cotranslational nascent protein modification in bacteria [Biochemistry]

The nascent polypeptide exit site of the ribosome is a crowded environment where multiple ribosome-associated protein biogenesis factors (RPBs) compete for the nascent polypeptide to influence their localization, folding, or quality control. Here we address how N-terminal methionine excision (NME), a ubiquitous process crucial for the maturation of over 50%…

Harvesting synergy from sustainable development goal interactions [Sustainability Science]

As countries pursue sustainable development across sectors as diverse as health, agriculture, and infrastructure, sectoral policies interact, generating synergies that alter their effectiveness. Identifying those synergies ex ante facilitates the harmonization of policies and provides an important lever to achieve the sustainable development goals (SDGs) of the United Nations 2030…

Glia-derived exosomal miR-274 targets Sprouty in trachea and synaptic boutons to modulate growth and responses to hypoxia [Developmental Biology]

Secreted exosomal microRNAs (miRNAs) mediate interorgan/tissue communications by modulating target gene expression, thereby regulating developmental and physiological functions. However, the source, route, and function in target cells have not been formally established for specific miRNAs. Here, we show that glial miR-274 non-cell-autonomously modulates the growth of synaptic boutons and tracheal.

New study: 1 in 7 child deaths result from pneumonia, the flu, & other LRIs

Despite large declines since 1990 in child deaths from pneumonia and the flu, these and other lower respiratory infections (LRIs) remain a leading killer of children under age 5. A new scientific study finds LRIs responsible for one in seven child deaths globally. 'Our findings reveal no 'one size fits all' solution exists to reduce child mortality significantly from LRIs in every country,' said D
