'A single piece of plastic' can kill sea turtles, says study

Science
A new study suggests that ingesting even a single piece of plastic can be deadly for sea turtles.Researchers found there was a one in five chance of death for a turtle who consumed just one item - rising to 50% for 14 pieces. The team found that younger turtles are at a higher risk of dying from exposure to plastic than adults. The authors say their research raises concerns over the long term survival of some turtle species.The never ending surge of plastic into the world's oceans is taking an increasing toll on iconic marine species. While it has been relatively straightforward for researchers to document the threat to animals who become entangled in plastic and drown, determining the impact of consumed plastic is much harder.The authors of this study es...

ESA scientists piece together last image captured by Rosetta probe

Science
Sept. 28 (UPI) -- European Space Agency scientists have pieced together one final image from the Rosetta probe's last telemetry packets, collected right before the craft crash landed on the surface of Comet 67P/Churyumov-Gerasimenko.Roughly a year ago, Rosetta attempted to land on the snowman-shaped comet. The landing didn't go as smoothly as hoped, but the probe collected a wealth of data and images before it tumbled into a sunless crater.Until recently, scientists thought they'd already seen Rosetta's last image, but while parsing the probe's last bits of data, ESA researchers found a few remaining telemetry packets. Scientists were able to piece the data fragments into one last snapshot of Comet 67P."The last complete image transmitted from Rosetta was the final one that we saw arriving...
