Abstract: More than two decades have passed since the first studies documenting genetic population structure of green turtles (Chelonia mydas) were published. Since then many more have followed and characterization [...]

Describes two studies that assessed decision-making skills using common cognitive errors and evaluated the impact of computer-based role-playing exercises on the development of these skills. Results with high school students, undergraduates, and earth science professionals are discussed which indicate that well-designed computer-based laboratories can positively impact higher-order cognitive skills.

The contagion of COVID-19 has made deadly that for which human beings yearn: touch. We must be satisfied, for now, with only prophylactic contact. A similar ambivalence haunts the notion of touch in Scripture: touch heals, but also contaminates, and even destroys. Despite the sentimentality of the Sistine Chapel, direct contact between God and Adam is deeply problematic. The hand of God touches/strikes the Egyptians with the plagues. The touch of the angel dislocates Jacob's hip. Uzzah's presumptuous touch of the ark of the covenant kills him. The Israelites may not touch the mountain in the desert. Who may know the divine touch, and live? The paper investigates this question with the assistance of Jacques Derrida and Katherine Sonderegger. [ABSTRACT FROM AUTHOR]

Thermolysis of the Pt(IV) alkyl hydride complex K(super 3)-Tp(super Me)2-Pt(super IV)(CH(sub 3))(sub 2)(H) leads to reductive elimination of methane. A lower energy C-H bond forming and cleaving process scrambles hydrogen atoms between the hydride and methyl positions of K(super 3)-Tp(super Me)2-Pt(super IV)(CH(sub 3))(sub 2)(H).

Background and Aims The health consequences of coronavirus disease 2019 [COVID-19] among patients with ulcerative colitis [UC] and Crohn's disease [CD] remain largely unknown. We aimed to investigate the outcomes and long-term effects of COVID-19 in patients with UC or CD. Methods We conducted a prospective, population-based study covering all Danish patients with CD or UC and confirmed COVID-19 between January 28, 2020 and April 1, 2021, through medical records and questionnaires. Results All 319 patients with UC and 197 patients with CD who developed COVID-19 in Denmark were included in this study and compared with the Danish background population with COVID-19 [ N = 230 087]. A significantly higher risk of COVID-19-related hospitalization was observed among patients with UC (N = 46 [14.4%], relative risk [RR] = 2.49 [95% confidence interval, CI, 1.91–3.26]) and CD (N = 24 [12.2%], RR = 2.11 [95% CI 1.45–3.07]) as compared with the background population (N = 13 306 [5.8%]). A similar pattern was observed for admission to intensive care (UC: N = 8 [2.51%], RR = 27.88 [95% CI 13.88–56.00]; CD: N = 3 [1.52%], RR = 16.92 [95% CI 5.46–52.46]). After a median of 5.1 months (interquartile range [IQR] 4.5–7.9), 58 [42.3%] and 39 [45.9%] patients with UC and CD, respectively, reported persisting symptoms which were independently associated with discontinuation of immunosuppressive therapies during COVID-19 (odds ratio [OR] = 1.50 [95% CI 1.07–10.22], p = 0.01) and severe COVID-19 (OR = 2.76 [95% CI 1.05–3.90], p = 0.04), but not with age or presence of comorbidities. Conclusion In this population-based study of 516 patients with IBD and COVID-19, 13.6% needed hospitalization and 2.1% required intensive care. Furthermore, sequelae were frequent, affecting 43.7% of COVID-19-infected patients. These findings might have implications for planning the healthcare of patients in the post-COVID-19 era.
