The forgotten wine: Understanding palm wine fermentation and composition.
Int J Food Microbiol
December 2024
Palm wine is an alcoholic beverage that has existed for centuries and has important economic and socio-culture values in many tropical and sub-tropical countries. Lesser known than other types of wines, palm wine is made by spontaneous fermentation of palm sap by naturally occurring microbial communities. The palm sap ecosystem has unique microbial composition and diversity, which determines the composition of the eventual wine and is likely affected by geographical distinctiveness.

Randomized placebo-controlled zinc supplementation trials have demonstrated improved glycemic traits in patients with type II diabetes (T2D). Moreover, rare loss-of-function variants in the zinc efflux transporter reduce T2D risk.

Considering the multifinality of outcomes following CV and guided by Bronfenbrenner's ecological systems framework, the current study sought to examine individual, microsystem, and exosystem level factors in relation to PTSS, anger, and resilience. Participants were 536 emerging adults ( = 20.

Article Synopsis
- Exposure to direct and intergenerational adversity can lead to increased depressive symptoms in Black adolescents, who are particularly vulnerable due to systemic racism and stress, yet many do not develop mental health issues.
- The study involved 141 Black adolescents (ages 11-17) and assessed factors like internal assets, mother-adolescent communication, and community support to understand their protective roles against depression.
- Results showed that less exposure to adversity, stronger internal assets, and effective communication with mothers were linked to fewer depressive symptoms, suggesting that improving family communication and personal strengths could help mitigate depression in Black youth.
Article Synopsis
- Combining data from different satellite sensors is crucial for accurately understanding methane emission trends and uncertainties, but this requires a thorough characterization of the probability of detection (POD), which can be expensive and time-consuming.
- Recent aerial surveys in August 2023 aimed to synchronize with NASA's EMIT observations to assess detection limits and to create a framework for combining multiple sensors, highlighting the importance of accurate POD assessment to avoid underestimating emissions from persistent sources.
