The University of Oklahoma fires instructor who gave failing grade to Bible-based gender essay
The University of Oklahoma has fired an instructor who was accused by a student of religious discrimination. The complaint from 20-year-old junior Samantha Fulnecky was over a failing grade on a psychology paper in which she cited the Bible and called promoting a belief in multiple genders “demonic.” The university said Monday that its investigation found that the graduate teaching assistant had been arbitrary in giving Fulnecky zero points on the assignment. The attorney for instructor Mel…

The city’s chief, Brian O’Hara, confirmed the man had died following the incident, describing him as a white male and a resident of Minnesota.
The man was also a “lawful gun owner” with a permit to carry the weapon, O’Hara said, adding that the victim’s name was known to police but would yet be released.

I haven’t tuned into CBS since its morning news promoted that interview (and Weiss) last week. This latest announcement validates my decision.

CBS News launches town hall series featuring JD Vance following Bari Weiss’ ratings flop
Following the Bari Weiss-moderated sitdown with Erika Kirk that was a massive ratings flop, CBS News has doubled down on the format and is launching a new town hall series in partnership with Weiss’ “anti-woke” digital media outlet that the network’s parent company recently purchased.

Made new test prints on some off-cuts, using a slightly stronger developer solution than usual to see impact on max. depth. The main image (Eagle Creek, Oregon) is using 18% sodium acetate (curve corrected negative), the test strips are of 20% and 15% solutions (both uncorrected). The phone capture doesn't really show the differences too well, but I think I will go for the 18-20% from now on...

A minimal wake-vortex model explains formation flight of flapping birds

Abstract: Collective patterns of motion emerge across biological taxa: insects swarm, fish school, and birds flock. In particular, large migratory birds form strikingly ordered V-shaped formations, which experiments and direct numerical simulations have demonstrated provide substantial energetic benefits during long-distance flight. However, the precise aerodynamic and morphological mechanisms underlying these benefits remain unclear. In this work, we develop a reduced-order model of the wake-vortex interactions between two flapping birds flying in tandem. The model retains essential unsteady flapping dynamics while remaining computationally tractable. By optimizing over a six-dimensional state space, which comprises the follower's three-dimensional relative position and three independent flapping parameters, we identify the energetically optimal leader-follower configuration of northern bald ibises. The predicted optimum agrees quantitatively with live-bird measurements. Because of its simplicity, the model allows for direct interrogation of the physical mechanisms responsible for this optimum. In particular, it isolates precisely how the follower's wing kinematics interact with the leader's wake to enhance aerodynamic efficiency. The model predicts an 11% reduction in total mechanical power for a follower in formation flight -- consistent with experimental estimates -- and shows that this saving arises from reductions in both induced and profile power, dominated by decreased profile power enabled primarily through reduced flapping amplitude and, secondarily, reduced upstroke flexion. These results provide a mechanistic explanation for the structure of V-formations and offer new insight into the aerodynamic principles governing collective flight.
