Effects of past anthropogenic metal pollution on the wildlife are understudied. We investigate trace element incorporation in the dentition of a 1000 BP-year-old brown bear from the Romanian Carpathians, an area known historically for strong metallurgical activities. Background values as well as unnatural high lead (Pb), lithium (Li) and zinc (Zn) levels in a circa 5‒6-year-old brown bear male were detected using trace element maps across its functional dentition.

In the United States, the Food and Drug Administration (USFDA) prohibits distribution of fruit that is dropped from the plant and contacts the ground during harvest. This includes fruit which contacts the ground while attached to the plant, called "drooping" fruit. In the Southeastern US, tomato and pepper are trellised and grown on plastic mulch.

Floating photovoltaics (FPVs), solar panels installed on floating structures in freshwater ecosystems such as lakes, represent a growing renewable technology aimed at decarbonizing the energy sector. However, robust empirical assessments of its environmental effects are still lacking. We used a Before-After-Control-Impact design replicated at the ecosystem level (n = 6 lakes: three lakes with FPV compared to three non-FPV lakes) to determine the global effects of FPV on water temperature over three years and allowing to isolate FPV effects from natural variability.

Background: Health worker migration from Nigeria poses significant challenges to the Nigerian health care sector and has far-reaching implications for health care systems globally. Understanding the factors driving migration, its effects on health care delivery, and potential policy interventions is critical for addressing this complex issue.
Objective: This study aims to comprehensively examine the factors encouraging the emigration of Nigerian health workers, map out the effects of health worker migration on the Nigerian health system, document the loss of investment in health training and education resulting from migration, identify relevant policy initiatives addressing migration, determine the effects of Nigerian health worker migration on destination countries, and identify the benefits and demerits to Nigeria of health worker migration.
