Gravitational collapse in energy-momentum squared gravity: Nature of singularities
Nuclear Physics BIn this paper we explore a collapsing scenario in the background of energy-momentum squared gravity (EMSG). EMSG claims to have terms that originate from the quantum gravity effects mimicking loop quantum gravity.

Programmable Nanoscale Motion via Molecular Patterning on DNA Origami
Angewandte Chemie, EarlyView.DNA origami nanorods enable precise urease placement with tunable coverage and asymmetry, revealing that propulsion depends on a balance of catalytic loading and geometry. Maximum speed occurs at ∼25% end‐coverage and declines as enzyme distribution becomes more symmetrical.
