Measuring electron emission from irradiated biomolecules
When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionize the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions. So far, however, researchers' understanding of the process ha

Making N-C bonds directly from dinitrogen: Summary and perspective
As the most abundant constituent in Earth's atmosphere, dinitrogen (N2) is the main nitrogen source of N-containing compounds in the Earth. Therefore, N2 fixation and activation are essential both for nature and humans. Nevertheless, the high bond dissociation energy (942 kJ/mol) and large HOMO-LUMO gap (10.82 eV) make N2 exhibit extremely low reactivity and may be regarded as an inert gas.

Nature Communications, Published online: 07 August 2020; doi:10.1038/s41467-020-17752-x Zinc affinity plays a key role in the zinc plating and stripping processes but its internal mechanism is still unclear. Here, the authors report a protective layer with controllable zinc affinity by adjusting the crystal orientation to suppress the dendrite growth on the zinc anode interface.

A nature-inspired hydrogen-bonded supramolecular complex for selective copper ion removal from water
Nature Communications, Published online: 07 August 2020; doi:10.1038/s41467-020-17757-6 Heavy metals and metalloids pose major threats to health and environmental ecosystems, thus systems for low-cost remediation are needed. Here the authors report the scalable design of a hydrogen-bonded organic–inorganic framework for selective removal of trace heavy metal ions from water.

PIP2: A critical regulator of vascular ion channels hiding in plain sight [Physiology]
The phosphoinositide, phosphatidylinositol 4,5-bisphosphate (PIP2), has long been established as a major contributor to intracellular signaling, primarily by virtue of its role as a substrate for phospholipase C (PLC). Signaling by Gq-protein–coupled receptors triggers PLC-mediated hydrolysis of PIP2 into inositol 1,4,5-trisphosphate and diacylglycerol, which are well known to modulate vascular…
