The world's e-waste -- discarded products with a battery or plug -- reached a staggering 44.7 million metric tonnes in 2016 -- up 3.3 Mt or 8 percent from 2014. In 2016 world e-waste -- everything from end-of-life refrigerators and television sets to solar panels, mobile phones and computers -- equaled in weight almost nine Great Pyramids of Giza, or 1.23 million fully loaded 18-wheel 40-ton trucks, enough to form a line from New York to Bangkok and back.
A checklist and coaching intervention to improve facility-based childbirth care and reduce deaths of women and newborns in India achieved significant gains in the quality of care during labor and delivery, but the improvements were insufficient to reduce death rates, according to a new study.
A study publishing Dec. 12 in the open-access journal PLOS Biology by Johanna Espin, Emilio Bruna, and colleagues at the University of Florida finds that while scientists from an increasing number of countries are represented in the scientific journals in which scientists report their results, the editors of these journals are a far less diverse group.
A study by the University of Cincinnati found that the rare Henst's goshawk of Madagascar hunts lemurs in low-lying areas that are most at risk to deforestation. Researchers could use this isotope analysis to study the habitat and prey needs of other threatened species that are difficult to track.
A new study of four South Asian countries argues that early marriage should be considered a major public health issue, due to its complex associations with women's education, health and nutrition -- which may also affect the next generation of children. The study also finds that increased education has had some, but not enough, success in delaying girls' marriage.
The UN-backed Global Alliance for Buildings and Construction predicts that the floor area of buildings worldwide (235 billion m2 in 2016) will roughly double by 2060, some 230 billion m2 of additional buildings -- the equivalent of all the buildings in Japan added every year; a Paris every week. While energy intensity of the buildings sector has improved, it isn't enough to offset rising energy demand. Ambitious action is needed to avoid locking in long-lived, inefficient buildings assets for decades.
In a new study comparing smoking rates and regulations between the US and Turkey, Mansoo Yu, associate professor of social work at the University of Missouri, found the rate of current smoking is higher in Turkey at 27 percent compared to the US at 18 percent.
A new mapping technique, described in the Nov. 14 issue of the Proceedings of the National Academies of Sciences, shows how researchers are developing computational tools that combine cellphone records with data from satellites and geographic information systems to create timely and incredibly detailed poverty maps. Unlike surveys or censuses, which can take years and cost millions of dollars, these maps can be generated quickly and cost-efficiently.
Newly emerging trends in data suggests humans may have reached their maximum limits for height, lifespan and physical performance. These biological limitations may be affected by anthropogenic impacts on the environment -- including climate change -- which could have a deleterious effect on these limits. This review is the first of its kind spanning 120 years worth of historical information, while considering the effects of both genetic and environmental parameters.
Yemenis face serious mental health risks, but the issue is being neglected. In a new study released today, the researchers reveal how serious the risk to mental health is in Yemen. Yet, mental health services in Yemen are few, and there is little research on the effects of the war on the mental health of the population. The paper also analyzes the long-term costs of failing to respond.
