The rich tapestry of life on Earth is fraying, due in large part to human-caused habitat loss and climate change. As more species disappear, researchers are racing to track this global decline in biodiversity to understand its consequences and counteract it through conservation initiatives. Those efforts rely on accurate animal monitoring, which can be difficult, time-consuming and costly. Now, in new research published in the journal iScience, researchers present evidence for a new low-cost, noninvasive tool that can be used to monitor animals: spiderwebs. They're using environmental DNA, or eDNA, which is simply different creatures' DNA just lying around in the environment. Previous work showed that webs are good sources of insect DNA, including what spiders are gorging on. But [evolutionary biologist Morton] Allentoft and [student Josh] Newton wanted to see whether the webs were also trapping DNA from vertebrate animals. So Newton ... collected spiderwebs. Back in the lab, Newton amplified the small amounts of DNA from the webs. They were filled with genetic material from animals. "It was wonderful," says Allentoft. "We could see these kangaroos [and] wallabies." There were nine other mammals, 13 species of birds, the motorbike frog and the snake-eyed skink. In other words, the technique worked. It represents a new way of tracking animal biodiversity and alerting us when we should intervene to conserve native species.

Many studies have shown that people living in greener neighborhoods have several health benefits, including lower levels of stress and cardiovascular disease. But new research indicates that exposure to parks, trees and other green spaces can slow the rates at which our cells age. The study, published in Science of the Total Environment, found that people who lived in neighborhoods with more green space had longer telomeres, which are associated with longer lives and slower ageing. Telomeres are structures that sit on the ends of each cell's 46 chromosomes, like the plastic caps on shoelaces, and keep DNA from unraveling. The longer a cell's telomeres, the more times it can replicate. When telomeres become so short that cells can't divide, the cells die. [Study co-author Aaron] Hipp and his colleagues looked at the medical records (that included measures of telomere lengths from biological samples) and survey responses from more than 7,800 people who participated in a national Centers for Disease Control and Prevention survey conducted between 1999 and 2002. The researchers connected that information with census data to estimate the amount of green space in each person's neighborhood. They found that a 5% increase in a neighborhood's green space was associated with a 1% reduction in the ageing of cells. "The more green the area, the slower the cell ageing," said Hipp.
