Some 15 billion years ago the universe emerged from a hot, dense sea of matter and energy. As the cosmos expanded and cooled, it spawned galaxies, stars, planets and life.

Oxygen evolution reaction (OER) is a half-reaction that occurs at the anode during water electrolysis, and owing to its slow kinetics, it is the rate-limiting step in the process. Alloying with transition metal and combining with transition metal oxide supports are effective methods for modifying the electronic structure of noble metal catalysts and improving their catalytic properties. In this study, we synthesized IrCu/CoO hybrid nanostructures by attaching IrCu alloy nanoparticles onto CoO nanosheets.

Broadly neutralizing antibodies (bNAbs) could offer escape-tolerant and lasting protection against viral infections and therefore guide development of broad-spectrum vaccines. The increasing challenge posed by viral evolution and immune evasion intensifies the importance of the discovery of bNAbs and their underlying neutralization mechanism. Here, focusing on the pivotal viral protein VP4 of rotavirus (RV), we identify a potent bNAb, 7H13, exhibiting broad-spectrum neutralization across diverse RV genotypes and demonstrating strong prevention of virus infection in female mice.

However, the impact of doxy-PEP on antibiotic resistance acquisition in key members of our microbiomes, is as of yet unclear. For example, commensal are known reservoirs of resistance for gonococci through horizontal gene transfer (HGT), and are more likely to experience bystander selection due to doxy-PEP as they are universally carried.
