Life-history traits, such as size-at-maturity, are key parameters to model population dynamics used to inform fisheries management. Fishery-induced evolution, density-dependent effects, and global warming have been shown to affect size- and age-at-maturity, and resulting spawning stock biomass (SSB) in a wide range of commercial fish stocks. Marked changes in redfish biomass and environmental conditions in the Gulf of St.

- The researchers studied how adding a special chemical group (called nitration) to a protein called alpha-synuclein (a-syn) could impact its behavior in diseases like Parkinson's.
- They created different versions of this protein, some with the nitration and some without, to see how they formed larger structures (oligomers and fibrils).
- Their findings suggest that when a-syn has this nitration, it may stop the formation of harmful fibrils, which could be important for understanding and treating diseases linked to this protein.
Background: Tracking infectious diseases at the community level is challenging due to asymptomatic infections and the logistical complexities of mass surveillance. Wastewater surveillance has emerged as a valuable tool for monitoring infectious disease agents including SARS-CoV-2 and Mpox virus. However, detecting the Mpox virus in wastewater is particularly challenging due to its relatively low prevalence in the community.

- - The COVID-19 pandemic led to higher levels of depression, anxiety, and stress, with previous research showing that resilience can help mitigate these issues, yet there is limited research on this link specifically in Central America.
- - A study with 480 adults from Panama found that resilience plays a mediating role; those more affected by the pandemic experienced greater mental health symptoms due to lower resilience levels.
- - The study also showed that factors like sex and social support influence resilience, with women and those with lower perceived social support experiencing a stronger impact on their mental health from pandemic-related distress.
