Coastal communities at the forefront of climate change reveal valuable approaches to foster adaptability and resilience, according to a worldwide analysis of small-scale fisheries by Stanford University researchers.
Globally important for both livelihood and nourishment, small-scale fisheries employ about 90 percent of the world s fishers and provide half the fish for human consumption. Large-scale shocks like natural disasters, weather fluctuations, oil spills and market collapse can spell disaster, depending on the fisheries ability to adapt to change. In an assessment of 22 small-scale fisheries that experienced stressors, researchers revealed that diversity and flexibility are among the most important adaptive capacity factors overall, while access to financial assets was not as important for individual households as it was at the community scale. The research was published Jan. 23 in the journal

Bill Gates recently told Andrew Ross Sorkin on CNBC s Squawk Box.
Nuclear power has to overcome a baneful reputation garnered by association with the atomic bomb and radioactive disasters, but it s a necessary, worthy and surmountable challenge to correct the naysayers, according to Gates.

That s because the need for clean energy is dire, and the operation of nuclear power plants produces no greenhouse gas emissions. According to Gates, new innovations in nuclear technology (in which he is an investor) are making nuclear energy safer and more affordable, and countries around the world are starting to adopt nuclear power.

Children exposed to air pollution, such as wildfire smoke and car exhaust, for as little as one day may be doomed to higher rates of heart disease and other ailments in adulthood, according to a new Stanford-led study. The analysis, published in Nature
Scientific Reports, is the first of its kind to investigate air pollution s effects at the single cell level and to simultaneously focus on both the cardiovascular and immune systems in children. It confirms previous research that bad air can alter gene regulation in a way that may impact long-term health - a finding that could change the way medical experts and parents think about the air children breathe, and inform clinical interventions for those exposed to chronic elevated air pollution.
Tigers face uncertain futures primarily due to habitat fragmentation, human-wildlife conflict, and poaching.
As global tiger populations decline, so does their genetic diversity. But until now it’s been unclear how the animals’ dwindling numbers are affecting them at the genetic level.
To find out, researchers sequenced 65 genomes from four of the surviving tiger subspecies. The findings confirm that strong genetic differences exist between different tiger subspecies but show, surprisingly, that these differences emerged relatively recently, as Earth underwent a major climatic shift and our own species grew increasingly dominant.
“The increasing dominance of humans across the world means that our understanding of which attributes of species and populations are best suited to the Anthropocene becomes ever more important,” says Elizabeth Hadly, professor in environmental biology at Stanford University, referring to the proposed geological epoch marked by significant human im
Vector-borne diseases shaped human history and reveal race disparities
In December 2015, a yellow fever outbreak began in Luanda, Angola. This outbreak was the largest reported in Angola during the last 30-years. In a new study, researchers examine the ways in which vector-borne diseases, like yellow fever, have shaped society and culture.

Vector-borne diseases shaped human history and reveal race disparities

UNIVERSITY PARK, Pa. Vector-borne diseases (VBDs), such as plague, malaria and yellow fever, have significantly shaped society and culture, according to an international team of researchers. In a study published in Ecology Letters on Jan. 27, the team used historical evidence interpreted through an ecological lens to illustrate how VBDs have influenced human history, with particular attention to how VBDs have reinforced and exacerbated racism.
