Antibody-mediated broad sarbecovirus neutralization through ACE2 molecular mimicry

Young-Jun Park et al.

Summary: Understanding broadly neutralizing sarbecovirus antibody responses is crucial for developing countermeasures against SARS-CoV-2 variants and future sarbecoviruses. The human monoclonal antibody S2K146 has been found to broadly neutralize ACE2-binding viruses and shows potential for clinical development. Conserved ACE2-binding residues could be leveraged for developing vaccines that elicit broad immunity.

Inverse Domain-Size Dependence of Piezoelectricity in Ferroelectric Crystals

Bo Wang et al.

Summary: The study reveals that the larger the domain size, the higher the piezoelectricity of ferroelectric crystals, contrary to previous beliefs. The dependence of piezoelectricity on domain size is determined by the propensity of polarization rotation inside the domains.
