Tacking—a maneuver used to sail a boat against the wind, changing direction in a zig-zag fashion—is one of the most difficult but necessary sailing maneuvers. While tacking is common, the movement of the sails and wind forces during the turn are not well understood. A new study by New York University and University of Michigan mathematicians addresses these matters head-on. It offers a detailed characterization of how sails behave during a wide range of tacking motions and with an array of sail types.

A research team uncovers a crucial molecular pathway by which sucrose, long known as a key energy source, also acts as a signaling molecule to regulate seed storage protein synthesis in maize.

Integrated carbon capture and utilization (ICCU) has become a promising technology to achieve carbon neutrality. However, conventional studies focused on the development of novel dual-functional materials while neglecting the impact of common impurities such as sulfur oxides (SOx) and nitrogen oxides (NOx), thereby limiting the practical industrial applicability of ICCU technology. A team of scientists has investigated the impact of SO₂ and NO₂ on the ICCU-dry reforming of methane (ICCU-DRM) process using a representative Ni-Ca dual-functional material. Their work is published in the journal Industrial Chemistry & Materials on 04 July 2025.
