Unlocking 'the shape of water' in mechanisms of antibiotic resistance

Researchers captured and comparted hi-res images of ribosome structures from sensitive and resistant bacteria and report that a water molecule needed for antibiotic binding was not present in the ribosomes from the drug-resistant bugs.

New biomaterials can be 'fine-tuned' for medical applications

Researchers have succeeded in 'fine tuning' a new thermoplastic biomaterial to enable both the rate at which it degrades in the body and its mechanical properties to be controlled independently.

Bio-inspired: How lobsters can help make stronger 3D printed concrete

New research addresses some of the technical issues that still need to be solved for 3D printed concrete to be strong enough for use in more free-form structures. Researchers found lobster-inspired printing patterns can make 3DCP stronger and help direct the strength where it's needed. And combining the patterns with a concrete mix enhanced with steel fibers can deliver a material that's stronger than traditionally-made concrete.

Borrowing from birds, experts reduce search times for novel high-entropy alloys to seconds

Computational materials science experts have enhanced an algorithm that borrows its approach from the nesting habits of cuckoo birds, reducing the search time for new high-tech alloys from weeks to mere seconds.

New method makes better predictions of material properties using low quality data

By combining large amounts of low-fidelity data with smaller quantities of high-fidelity data, nanoengineers have developed a new machine learning method to predict the properties of materials with more accuracy than existing models. Crucially, their approach is also the first to predict the properties of disordered materials -- those with atomic sites that can be occupied by more than one element, or can be vacant.

Scientists measure local vibrational modes at individual crystalline faults

Employing newly developed electron microscopy techniques, researchers have, for the first time, measured the spectra of phonons - quantum mechanical vibrations in a lattice - at individual crystalline faults, and they discovered the propagation of phonons near the flaws.
