       Anyone got a high res version? This is Exhibit 1 from the Comey indictment. If the pic is from North Carolina coast, the 8 looks like mostly Dinocardium robusta, the giant Atlantic cockle. The 6 probably the same but stained by anoxic sediment. The 4+7 look like a mix of Crassostrea virginica (Eastern oyster) and Geukensia demissa (Eastern ribbed mussel). Maybe also some ponderous ark, Noetia ponderosa and maybe also a Glycymeris (bittersweet clam) in the 8 #clamFacts

       not enough people are asking, what is the water-speed velocity of an unladen scallop?

       I got a box. There was an office chair in it but that was secondary to the box part

       Pulse oximetry has previously been noted to have a bias against people with higher skin melanin content. It over-measures blood oxygen for Black people and others with more melanin, because most oximeters were calibrated for people with light skin. This can lead to someone with a real blood O2 reading of 91% reading as 94%. A new study shows that has led to different levels of follow-up care, with Black patients being less likely to receive supplemental oxygen as a result of this systematic mismeasurement. I was recently caring for my mom when she had a severe infection. During the recovery phase, she had supplemental oxygen at home and I literally had a pulse oximeter hanging on my neck like a pendant, taking spot checks frequently of her oxygen. It was already scary enough and I can't imagine not being able to trust the readings of what should be a life-saving device! This is why systemic racism is so insidious and pops up in all sorts of subtle but fundamental ways, especially when science is contaminated by the racist thinking! It makes me wonder what other effects this has had? Has this contributed to the known under-diagnosis of Black patients with sleep apnea? It's scary to think about.https://news.stanford.edu/stories/2026/05/pulse-oximeter-bias-black-patients-follow-up-care
