The eminent protein sources among the vegetarian population include cereals and pulses that do not satisfy the Recommended Dietary Allowance (RDA) level. The anti-nutrients such as protease inhibitors are responsible for the diminished bioavailability of plant protein. Consumption of a protein deficit diet severely impacts muscle health; hence, it becomes necessary to design an alternative source of complete protein. One such non-meat source with all essential amino acids in required quantity is seaweeds, an aquatic plant.

Background: Increasing air conditioner use for cooling indoor spaces has the potential to be a primary driver of global greenhouse gas emissions. Moving indoor air with residential fans can raise the temperature threshold at which air conditioning needs to be turned on to maintain the thermal comfort of building occupants. We investigate whether fans can be used to reduce air conditioner use and associated greenhouse gas emissions.

Background: Air pollution might accelerate cognitive ageing; it is unclear whether large-scale interventions, such as China's Clean Air Act (CCAA), can mitigate cognitive deterioration. We aimed to evaluate the effect of CCAA on changes in cognitive function in older adults. Methods: In this population-based, quasi-experimental study, we did a difference-in-differences analysis of the data collected during the 2014 and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS).

Temperature affects many life processes, but its effect might be expected to differ among eukaryotic organisms inhabiting similar environments. We reviewed literature on temperature thresholds of humans, livestock, poultry, agricultural crops, and sparse examples of fisheries. We found that preferable and harmful temperatures are similar for humans, cattle, pigs, poultry, fish, and agricultural crops. Preferable temperatures range from 17°C to 24°C. Stress temperature thresholds are lower when humidity is higher.

Climate change can have detrimental effects on child health and wellbeing. Despite the imperative for a fuller understanding of how climate change affects child health and wellbeing, a systematic approach and focus solely on children (aged <18 years) has been lacking. In this Scoping Review, we did a literature search on the impacts of climate change on child health from January, 2000, to June, 2019. The included studies explicitly linked an alteration of an exposure to a risk factor for child health to climate change or climate variability.

Microplastics (MPs) are found in all conceivable media from air, sediments, soils, freshwater, seawater, and organisms, including humans. This paper emphasizes current advances in the study of MPs and presents a review of recent two years of literature on the occurrence and fate of these particles in the environment. The occurrence and fate of MPs are affected by their characteristics and interaction with the media in the environment, including particle mobility and transport processes.
