Study captures six galaxies undergoing sudden, dramatic transitions

Galaxies come in a wide variety of shapes, sizes and brightnesses, ranging from humdrum ordinary galaxies to luminous active galaxies. While an ordinary galaxy is visible mainly because of the light from its stars, an active galaxy shines brightest at its center, or nucleus, where a supermassive black hole emits a steady blast of bright light as it voraciously consumes nearby gas and dust.

New hunt for dark matter

Dark matter is only known by its effect on massive astronomical bodies, but has yet to be directly observed or even identified. A theory about what dark matter might be suggests that it could be a particle called an axion and that these could be detectable with laser-based experiments that already exist. These laser experiments are gravitational-wave observatories.

Att uttrycket ”en riktig söderböna” inte ska tas bokstavligt har människor lätt att förstå. Från tidig ålder lär vi oss nämligen att ord kan ha flera betydelser. Blir vi osäkra finns det lexikon till hjälp, där lingvister lagt tusentals timmar på att katalogisera ordens olika betydelser. Men de flesta mjukvaror som tolkar text arbetar inte alls på samma sätt, och de fel det kan resultera i har du

As Droughts Spread Across India, So Does Water Budgeting

In India, the world’s largest user of groundwater, parched rural communities face severe water shortages due to recurring droughts and unregulated extraction. Cooperation may be the key to conservation: Now, villages are banding together to preserve their limited resources using water budgets.

How can cognitive science inform the future of education?

The education field has a wealth of cognitive science research that reveals how people learn, yet the applied practice happening is schools shows an enormous disconnect. Things like school bells, siloed 'one-hour-one-subject' classes, traditional grades, and standardized testing are outdated design features of the education system. Equitably educating all learners across diverse populations to he

The impact origin and evolution of Chryse Planitia on Mars revealed by buried craters

Nature Communications, Published online: 18 September 2019; doi:10.1038/s41467-019-12162-0 Due to active geological resurfacing, the record of large impact basins (e.g. in Chryse Planitia) on Mars seems to be widely absent. Based on high-quality global datasets, the authors here propose a buried impact basin, covered by up to 1 km of sediments or lava flows after its formation more than 4 billion

Modular enzyme assembly for enhanced cascade biocatalysis and metabolic flux

Nature Communications, Published online: 18 September 2019; doi:10.1038/s41467-019-12247-w Metabolic enzymes often form supramolecular complexes to improve product yield. Here the authors use short peptide tags to create scaffold-free assemblies and synthetic metabolic nodes.

Dynamic regulation of interregional cortical communication by slow brain oscillations during working memory

Nature Communications, Published online: 18 September 2019; doi:10.1038/s41467-019-12057-0 Working memory involves a fronto-parietal brain network, but how the parts of this network are coordinated is unclear. Here, the authors show that fast brain activity at posterior sites is nested into prefrontal slow brain waves, with cognitive demand determining the slow wave phase involved.

Here the authors show, using mouse model of adoptive cell transfer, that CD4-CD8- T cells can suppress the function of dendritic cells and T follicular helper cells via Lag3 to provide a

A Bayesian psychophysics model of sense of agency

Nature Communications, Published online: 18 September 2019; doi:10.1038/s41467-019-12170-0 Sense of agency (SoA) refers to the experience that one's own actions caused an external event. Here, the authors present a model of SoA in terms of optimal Bayesian cue integration taking into account reliability of action and outcome sensory signals and judging if the action caused the outcome.

Heme and hemoglobin utilization by Mycobacterium tuberculosis

Nature Communications, Published online: 18 September 2019; doi:10.1038/s41467-019-12109-5 Iron is essential for growth of Mycobacterium tuberculosis, but most of the iron in the human body is stored in heme within hemoglobin. Here, Mitra et al. identify two heme uptake mechanisms in M. tuberculosis, one dependent on the inner-membrane Dpp importer and the other dependent on host albumin.

Perfect proton selectivity in ion transport through two-dimensional crystals

Nature Communications, Published online: 18 September 2019; doi:10.1038/s41467-019-12314-2 Defect-free monolayers of graphene and hexagonal boron nitride are highly permeable to thermal protons, but are impenetrable to gases. Here the authors show that mechanically exfoliated crystals exhibit perfect proton selectivity, corroborating proton transport through the bulk without atomic-scale defects.

Scientists construct energy production unit for a synthetic cell

Scientists at the University of Groningen have constructed synthetic vesicles in which ATP, the main energy carrier in living cells, is produced. The vesicles use the ATP to maintain their volume and their ionic strength homeostasis. This metabolic network will eventually be used in the creation of synthetic cells – but it can already be used to study ATP-dependent processes. The researchers descr
