Article Synopsis
- The CNO cycle is a key nuclear energy process in stars, particularly significant in hydrostatic hydrogen burning at temperatures between 20 to 80 MK.
- This study reports the first direct measurements of the resonance strength of the ^{17}O(p,γ)^{18}F reaction, revealing a strength about twice as high as previously documented.
- The findings enhance our comprehension of oxygen isotopic ratios observed in red giant stars and in O-rich presolar grains, confirming consistency with earlier results from different reaction channels.
A theoretical perspective on grandiose narcissism suggests four forms of it (sanctity, admiration, heroism, rivalry) and states that these forms conduce to different ways of thinking and acting. Guided by this perspective, we examined in a multinational and multicultural study (61 countries; N = 15,039) how narcissism forms are linked to cognitions and behaviors prompted by the COVID-19 pandemic. As expected, differences in cognitions and behaviors across narcissism forms emerged.

In this study, we develop a functional, pooled screening platform to identify protein-based reagents that improve HDR in human hematopoietic stem and progenitor cells (HSPCs). We leverage this screening platform to explore sequence diversity at the binding interface of the NHEJ inhibitor i53 and its target, 53BP1, identifying optimized variants that enable new intermolecular bonds and robustly increase HDR.

The optimal timing of UFH administration (before or after TSP) is unknown. The Strategy To Optimize PeriproCeduraL AnticOagulation in Structural Transseptal Interventions trial (STOP CLOT Trial) was designed to determine if early anticoagulation is effective in reducing ischemic complications without increasing the risk of periprocedural bleeding.
