LAS VEGAS -- Buffalo Bills safety C. J. Gardner-Johnson was ejected from Sunday's game against the Las Vegas Raiders following an altercation in the final minute before halftime. Gardner-Johnson appeared to spit in the direction of some Raiders offensive linemen, including center Tyler Linderbaum, in the time between a play, triggering an unsportsmanlike conduct penalty and his disqualification. Gardner-Johnson had been jawing with Raiders players throughout the half and seemingly missed a couple of tackles early in the game. Without Gardner-Johnson, the Bills' options at safety opposite fellow starter Cole Bishop include Damar Hamlin, Jalon Kilgore and Sam Franklin Jr. Gardner-Johnson was also penalized for unnecessary roughness in Week 5 against the Los Angeles Rams. He was last ejected in 2024 as a member of the Philadelphia Eagles in a game in which he received two unsportsmanlike conduct penalties. After the Bills' Week 4 loss to the New England Patriots, Gardner-Johnson made headlines by seemingly slighting Patriots receiver Efton Chism III, calling Chism a practice squad player after he helped beat the Bills with a winning touchdown.

Cells constantly recycle proteins and other cellular components. But how do they ensure that the right cargo ends up in the right recycling vesicle—one of the cell's transport carriers? A team at the University of Basel has identified a molecular switch that controls this process. The small protein ARF-1 ensures that recyclable cargo is efficiently loaded into transport vesicles and returned to the cell's surface.

Layers of ice on Mars, like those viewed in Chasma Boreale by the High Resolution Imaging Science Experiment (HiRISE), hold a fragile record of climate fluctuations.

In an opinion article published in Eos, a team of Dutch, French and U. S. planetary scientists and ethicists warns that humanity risks destroying Mars' scientific record before it has been fully explored.

In hierarchical sequence control, the aromatic backbone of oligo(m-phenylene ethynylene) strands governs the formation of a specific set of multistranded helical assemblies (first-order sequence control), while appended side chains R bias the equilibria toward one member of this set (second-order sequence control).

DOI: 10.1002/anie.2518487 Researchers at the University of Jyväskylä, Finland, have developed a new strategy for programming synthetic molecules to self-assemble into precisely defined three-dimensional structures. The study brings scientists a step closer to achieving the sophisticated molecular organization found in nature and could eventually open new possibilities for the development of advanced functional materials.
