Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, a team at the Technical University of Munich (TUM) systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.

If you think shopping is tedious, try juggling 200,000 products in a Walmart. Not literally, of course, but somehow keeping the shelves stocked over an area of tens of thousands of square feet. For that you need a worker with a barcode scanner and an enviable amount of patience.

For the first time, high-resolution images show the three-dimensional structure of massive ice deposits on Mars. According to an in-depth analysis led by the USGS, the images reveal never-before-observed details about the ice sheets, including that some begin just a few feet below the Martian surface and extend to depths greater than 300 feet.  

Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on January 9. NASA calculated the amount of rain fall between January 8 and 10, 2018 and calculated the potential for landslides.
