AI Article Synopsis
- Marine low clouds are crucial for the climate system and are influenced by the concentration of cloud condensation nuclei (CCN).
- Contrary to previous beliefs, new particle formation occurs regularly in the upper marine boundary layer after cold fronts, even in remote ocean areas.
- This process is driven by factors like precipitation removing existing particles, cold temperatures, vertical transport of reactive gases, and high light exposure, leading to the formation of new particles that enhance CCN and affect low cloud properties.
Article Abstract
Marine low clouds play an important role in the climate system, and their properties are sensitive to cloud condensation nuclei concentrations. While new particle formation represents a major source of cloud condensation nuclei globally, the prevailing view is that new particle formation rarely occurs in remote marine boundary layer over open oceans. Here we present evidence of the regular and frequent occurrence of new particle formation in the upper part of remote marine boundary layer following cold front passages. The new particle formation is facilitated by a combination of efficient removal of existing particles by precipitation, cold air temperatures, vertical transport of reactive gases from the ocean surface, and high actinic fluxes in a broken cloud field. The newly formed particles subsequently grow and contribute substantially to cloud condensation nuclei in the remote marine boundary layer and thereby impact marine low clouds.

Ionizing radiation induces various types of DNA damage, and the reparability and lethal effects of DNA damage differ depending on its spatial density. Elucidating the structure of radiation-induced clustered DNA damage and its repair processes will enhance our understanding of the lethal impact of ionizing radiation and advance progress toward precise therapeutics. Previously, we developed a method to directly visualize DNA damage using atomic force microscopy (AFM) and classified clustered DNA damage into simple base damage clusters (BDCs), complex BDCs and complex double-strand breaks (DSBs).

Diabetes is associated with increased atherosclerotic cardiovascular disease (ASCVD) risk, a leading cause of morbidity and mortality. Disordered lipid metabolism is a major contributor to ASCVD risk in diabetes. Dyslipidemia in type 2 diabetes is characterized by hypertriglyceridemia, low HDL cholesterol and the presence of small, dense LDL particles.

Background: Recently, we reported that longer-term mixed nut intake significantly reduced serum total and low-density lipoprotein (LDL)-cholesterol, but these markers may not fully capture lipoprotein-related cardiovascular disease (CVD) risk.
Objectives: This randomized, controlled, single-blinded, crossover trial in older adults with overweight or obesity examined the effects of longer-term mixed nut consumption on lipoprotein particle size, number, and lipid distribution.
Methods: Twenty-eight participants (aged 65 ± 3 years; BMI 27.
