Human pressures on the environment are changing spatially and temporally, with profound implications for the planet's biodiversity and human economies. Here we use recently available data on infrastructure, land cover and human access into natural areas to construct a globally standardized measure of the cumulative human footprint on the terrestrial environment at 1 km(2) resolution from 1993 to 2009. We note that while the human population has increased by 23% and the world economy has grown 153%, the human footprint has increased by just 9%. Still, 75% the planet's land surface is experiencing measurable human pressures. Moreover, pressures are perversely intense, widespread and rapidly intensifying in places with high biodiversity. Encouragingly, we discover decreases in environmental pressures in the wealthiest countries and those with strong control of corruption. Clearly the human footprint on Earth is changing, yet there are still opportunities for conservation gains.

Gene expression is coordinated by a multitude of transcription factors (TFs), whose binding to the genome is directed through multiple interconnected epigenetic signals, including chromatin accessibility and histone modifications. These complex networks have been shown to be disrupted during aging, disease, and cancer. However, profiling these networks across diverse cell types and states has been limited due to the technical constraints of existing methods for mapping DNA:Protein interactions in single cells.

To reduce carbon footprint and human dependence on fossil fuels, the field of bio-based polymers has undergone explosive growth in recent years. Among them, bio-based elastomers have gained tremendous attention for their inherent softness, high strain, and resilience. In this review, the recent progress of representative bio-based elastomers derived from molecular building blocks and biopolymers are recapitulated, with an emphasis on molecular design, synthesis approaches, and mechanical performance.

Objective: This study aimed to evaluate the relationship between nutrition literacy, Mediterranean diet compliance, ecological footprint and sustainable environmental attitudes in adolescents.
Methods: This descriptive and cross-sectional study was conducted with 673 adolescents aged 14-18 years. The individuals' general characteristics were questioned.

Climate change is an emerging global health crisis, disproportionately affecting low- and middle-income countries (LMICs) where health outcomes are increasingly compromised by environmental stressors such as pollution, natural disasters, and human migration. With a focus on promoting health equity, Global Surgery advocates for expanding access to surgical care and enhancing health outcomes, particularly in resource-limited and disaster-affected areas like LMICs. The healthcare industry-and more specifically, surgical care-significantly contributes to the global carbon footprint, primarily through resource-intensive settings, i.

: The water footprint (WF) provides information on the impact of individual foods on water consumption, but to better direct food production toward water saving, we need to understand how to reduce the WF of our diets while keeping it healthy. In this study, we compared the WF of healthy diets based on national food-based dietary guidelines with the aim of highlighting changes in dietary patterns that could reduce water requirements without compromising nutritional adequacy. : Three 2000 kcal/day dietary patterns were elaborated following the Italian, Spanish, and American dietary guidelines, and their total, green, blue, and grey WFs were calculated.
