This thoughtful case for mounting a lifelong challenge to our own assumptions focuses on unconscious bias – but leaves overt prejudice largely unexamined We often think of bias as a problem that other people have. It's harder to find someone willing to admit to it in themselves. That was what struck me reading American journalist Jessica Nordell's thoughtful book, The End of Bias, which I picked

Eliminating microplastics on farmland
In many countries, farmers and gardeners use mulch films to increase their crop yields.

Active Learning Is Best
There is pretty broad agreement that the pandemic was a net negative for learning among children. Schools are an obvious breeding ground for viruses, with hundreds or thousands of students crammed into the same building, moving to different groups in different classes, and with teachers being systematically exposed to many different students while they spray them with their possibly virus-laden d

Daily briefing: Jupiter's Great Red Spot is swirling faster
Nature, Published online: 30 September 2021; doi:10.1038/d41586-021-02683-4 The Great Red Spot storm on Jupiter is mysteriously rotating faster and shrinking. Plus, see the first images of a solid made of electrons and learn how Microsoft plans to offset all the carbon it ever emitted.

A primer for academic entrepreneurs on academic-industrial partnerships
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-26103-3 Partnerships between academic investigators and industry can accelerate the translation of research findings into life-saving products. The healthcare industry has witnessed heightened interest from universities in capitalizing on the discoveries made by faculty to create intellectual property, form new compa

In-situ anodic precipitation process for highly efficient separation of aluminum alloys
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-26119-9 Traditional electrorefining process is limited by deposition potential of the metal itself. Here, the authors explore an in-situ anodic precipitation process based on different solubility of target metal chlorides that can efficiently separate components of aluminum alloys.

The growing need for controlled data access models in clinical proteomics and metabolomics
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-26110-4 More and more clinical studies include potentially sensitive human proteomics or metabolomics datasets, but bioinformatics resources for managing the access to these data are not yet available. This commentary discusses current best practices and future perspectives for the responsible handling of clinical pr

Efficient propyne/propadiene separation by microporous crystalline physiadsorbents
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-25980-y The separation of propadiene from propyne/propadiene mixtures remains challenging. Here, the authors report a sorbent screening protocol and show that metal-organic frameworks (MOFs) with open metal sites and cage-based molecule traps exhibit high performance for propyne/propadiene separation.

Boson-peak-like anomaly caused by transverse phonon softening in strain glass
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-26029-w Strain glass is a new glassy state characterized by frozen ferroelastic nanodomains. Here, the authors discover a low-temperature feature in the specific heat of a strain glass, which is similar to the well-known boson peak anomaly of structural glasses, but cannot be explained by existing mechanisms.

Neurofibromin 1 in mushroom body neurons mediates circadian wake drive through activating cAMP–PKA signaling
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-26031-2 The molecular mechanism by which clock neurons transmit timing information to non-clock neurons is poorly understood. Here, the authors show that circadian clocks drive rhythmic expression of hundreds of genes in mushroom body neurons and drive calcium rhythms via NF1-cAMP/PKAC1 signalling in Drosophila.

Complex small-world regulatory networks emerge from the 3D organisation of the human genome
Nature Communications, Published online: 01 October 2021; doi:10.1038/s41467-021-25875-y Gene-regulatory networks are thought to be complex, and yet perturbation of just a few transcription factors (TFs) can have major consequences. Here the authors apply DNA polymer modelling and simulations to predict how 3D genome structure and TF-DNA interactions can give rise to transcriptional regulation op
