Advanced Science, EarlyView.Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

Biological Explanations of Social Inequalities
Pacific Philosophical Quarterly, Volume 103, Issue 4, Page 694-719, December 2022., 2022 Abstract Inequalities of social goods between gender, racial, or other groups call out for explanation. Such inequalities might be explained by socialization and discrimination. But historically some have attributed these inequalities to biological differences between social groups. Such explanations are highly controversial: on the one hand, they have

The effects of a solar eclipse on photo-oxidants in different areas of China [PDF]
Atmospheric Chemistry and Physics, 2011 This study investigates the effects of the total solar eclipse of 22 July 2009 on surface ozone and other photo-oxidants over China. A box model was used to study the sensitivity of ozone to the limb darkening effect during an eclipse event, and to show ...

Atmospheric Gravity Waves Observed in the Nightglow Following the 21 August 2017 Total Solar Eclipse
Geophysical Research Letters, 2020 Nighttime airglow images observed at the low‐latitude site of São João do Cariri (7.4°S, 36.5°W) showed the presence of a medium‐scale atmospheric gravity wave (AGW) associated with the 21 August 2017 total solar eclipse.

Advanced Science, EarlyView.Amidoxime‐functionalization sp2‐carbon‐conjugated organic framework (PTTN‐AO) is carefully designed and synthesized to increase hydrophilicity, stabilize adsorbed O2 via hydrogen bonding, and accelerate the charge separation and transfer. This strategy promotes the photocatalytic 2e− oxygen reduction reaction to produce hydrogen peroxide.

Advanced Science, EarlyView.The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...
