In conductors where both electrons and ions carry charge, scientists created an "ion superhighway." Potential applications include battery charging, biosensing, soft robotics, and neuromorphic computing. @berkeleylab.lbl.gov als.lbl.gov/building-a-g...
Journal-cover illustration of a four-lane highway, with the two left lanes marked with diamonds (indicating high-occupancy vehicle or “carpool” lanes). The right two lanes are “congested” with gel-like blobs. Red dots (representing ions) are stuck between blobs in the two right lanes, but move unimpeded in the two left lanes.

By locking down parts of a modular drug-building protein, researchers learned new details about how carrier proteins transfer the product protein between modules. The work could enable scientists to design and create new and improved medicines. @berkeleylab.lbl.gov als.lbl.gov/deep-dive-in...
Ribbon diagram of a protein complex. The main protein structure is white, and the carrier protein (which passes amino acids to and from functional domains) is green. The carrier protein is shown at the beginning and end points of a 180° swing.

Researchers developed a cheaper, more energy-efficient way to extract lithium from its source mineral, spodumene. The work supports the sustainable scaling of lithium production to meet growing market needs for hybrid and electric-vehicle batteries. @berkeleylab.lbl.gov als.lbl.gov/energy-savin...
Vertical flow chart showing steps in lithium extraction from spodumene: grinding, mixing, heating, washing, evaporation. In the background, diffraction data is presented as a heatmap-style graph, with green vertical lines on a blue background. The green lines represent the spectral fingerprints of the primary reaction products.

Some species of California lilac have developed an adaptation for arid climates: the stomatal crypt. Researchers characterized these crypts using microtomography, revealing how the crypts help plants survive drought. @berkeleylab.lbl.gov als.lbl.gov/the-secret-t...
Left: Photo of a lilac shrub with reddish buds. Right: 3D microtomographic visualization of a Ceanothus megacarpus leaf (green cube with section cut away). White arrows indicate stomata, which are found exclusively within crypts, or indentations, in the leaf. A 200 µm scale bar is included.

Researchers used soft x-ray resonant inelastic x-ray scattering at the ALS to understand the role of aluminum doping in improving the stability of commercially used cathode materials for lithium-ion batteries. @berkeleylab.lbl.gov als.lbl.gov/reaction-mec...
Comparison of RIXS data for a commonly used commercial cathode material, with and without aluminum doping. A feature associated with oxygen redox reactions is only present with aluminum doping. Accompanying molecular schematics show how aluminum doping might produce the observed behavior via a more stable structure.

By directly visualizing the uneven insertion of lithium ions into electrodes with well-defined crystal orientations, researchers learned why fast charging decreases battery lifespan and performance. @berkeleylab.lbl.gov als.lbl.gov/a-clearer-lo...
Journal-cover illustration showing a conical beam of green light from above passing through a planar crystalline sample, with the beam’s focal point at the surface of the sample. Lightning-like bolts arc from above to the sample. To the right, a block of ordered blue atoms is topped by a sprinkling of gold particles, with a transparent layer on top. The transparent layer is in the process of detaching from the blue/gold substrate. A completely detached transparent layer floats above.

Researchers used x-ray absorption spectroscopy and resonant inelastic x-ray scattering at the ALS to uncover the atomic-level mechanism of conductance switching for a neuromorphic material that has the potential for energy-efficient computing. @berkeleylab.lbl.gov als.lbl.gov/mind-blowing...
An artistic 3D illustration of neuromorphic computing, showing a close-up of a synapse (junction) between two “artificial neurons.” The neuron on the lower left contain a molecular crystal structure encased in a transparent material, and the one on the upper right has a dark surface printed with circuitry. Organic-looking neuron-like dendrites float in space around the artificial neurons.

Researchers @berkeleylab.lbl.gov encapsulated actinium within a macromolecular complex for analysis using protein crystallography and discovered that actinium has a unique solid-state bonding configuration. The work could help improve a promising cancer treatment. als.lbl.gov/a-macromolec...
Left: Protein crystallography provided information about how actinium (magenta sphere, center) binds to a scaffold consisting of a synthetic molecule (magenta sticks) and a mammalian protein (gray surface). The structure when lanthanum (gray sphere and sticks) is substituted for actinium is shown for comparison. Right: Details of the interactions of the actinium with oxygen in the rings of the synthetic ligand.

Researchers discovered two antibodies that can prevent the protein interactions responsible for severe malaria and elucidated their binding mechanism. These antibodies offer novel insights for vaccine design or targeted treatment. @berkeleylab.lbl.gov als.lbl.gov/identificati...
Left: A variant of the target domain for vaccines, CIDRα1.4 (light blue/yellow), in complex with a broadly reactive antibody, C7 (purple/maroon). Right: Superposition of the receptor protein, EPCR (gray surface), shows that C7 directly blocks the EPCR binding site (yellow helices), thus inhibiting the interaction responsible for severe malaria.
