Anthropogenic inputs of nitrogen and phosphorus to lakes have increased worldwide, causing phytoplankton chlorophyll concentrations to increase at many sites, with negative implications for biodiversity and human usage of lake resources. However, the conversion of nutrients to chlorophyll varies among lakes, hindering effective management actions to improve water quality. Here, using a rich global dataset, we explore how the relationship between chlorophyll-a (Chla) and nitrogen and phosphorus and inferred nutrient limitation is modified by climate, catchment, hydrology and lake characteristics.

Recent changes in ENSO's impacts on the summertime circumglobal teleconnection and mid-latitude extremes.

Nat Commun

January 2025

School of Atmospheric Sciences, Sun Yat-Sen University, and Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai, China.

The boreal summer circumglobal teleconnection (CGT) provides a primary predictability source for mid-latitude Northern Hemisphere climate anomalies and extreme events. Here, we show that the CGT's circulation structure has been displaced westward by half a wavelength since the late 1970s, more severely impacting heatwaves and droughts over East Europe, East Asia, and southwestern North America. We present empirical and modelling evidence of the essential role of El Niño-Southern Oscillation (ENSO) in shaping this change.

Prior research has linked the social determinants of health, such as food insecurity and housing instability, to experiences of interpersonal violence. However, little is known about how the social determinants of health are related to the risk for interpersonal violence among Black Americans living in rural, high-poverty communities in the Deep South. The intersection of rurality, racialized identity, and economic hardship makes this population particularly vulnerable to interpersonal violence, yet this population is underrepresented in the literature.

This paper reviews evidence about the impact of marketing on ill health. We summarize evidence that marketing practices in six industries (tobacco, alcohol, pharmaceutical, processed food, firearm, and fossil fuel) are causal influences on the occurrence of injury, disease, and premature death. For each industry, we provide a brief overview on the extent of harmful marketing, efforts from each industry to obscure or otherwise conceal the impact of their marketing strategies, and efforts to counter the impact of harmful marketing in these industries.

Illudin S inhibits p53-Mdm2 interaction for anticancer efficacy in colorectal cancer.

Biomed Pharmacother

January 2025

Department of Chemistry, Sungkyunkwan University, Suwon 16419, Republic of Korea. Electronic address:

The impairment of the p53 pathway was once regarded as inadequately druggable due to the specificity of the p53 structure, its flat surface lacking an ideal drug-binding site, and the difficulty in reinstating p53 function. However, renewed interest in p53-based therapies has emerged, with promising approaches targeting p53 and ongoing clinical trials investigating p53-based treatments across various cancers. Despite significant progress in p53-targeted therapies, challenges persist in identifying effective therapeutic targets within the p53 pathway.

The minimal group effect, in which people prefer ingroup members to outgroup members even when group membership is trivially constructed, has been studied extensively in psychological science. Despite a large body of literature on this phenomenon, concerns persist regarding previous developmental research populations that are small and lack racial/ethnic diversity. In addition, it remains unclear what role holding membership within and interacting with specific racial/ethnic groups plays in the development of children's group attitudes.
