Science Ask Us Anything The most eco-friendly burial option isn't cremation or human composting With more options than ever, we break down which one's best for the planet. Cemeteries are increasingly running out of space. Are there greener options we ought to turn to? Breakthroughs, discoveries, and DIY tips sent six days a week. Perhaps one of life's hardest tasks is deciding what to do with a loved one's--or even your own--bodily remains. Do you go the cremation route? If you want your last act on Earth to also be good for the Earth, what do you do?

The trend often mirrored their relationship with religion before their deaths, too--nobility and knights frequently ensured they sat in the front pews of services. Money is only one facet of social relations, however. Communities have long discriminated against and ostracized residents with debilitating illnesses--especially those with outward physical effects.

Breakthroughs, discoveries, and DIY tips sent every weekday. Do you know what want to have happen to your body after you die? Do you want to be cremated, buried, or given an epic Viking burial? While it may seem macabre, it's important to think about so our loved ones don't have to while their in the throes of grief. On this episode of, editors Sarah Durn and Annie Colbert dig into a novel way people are choosing to handle their bodies after they die: human composting.

Compiling large datasets from published resources, such as archaeological find catalogues presents fundamental challenges: identifying relevant content and manually recording it is a time-consuming, repetitive and error-prone task. For the data to be useful, it must be of comparable quality and adhere to the same recording standards, which is hardly ever the case in archaeology. Here, we present a new data collection method exploiting recent advances in Artificial Intelligence. Our software uses an object detection neural network combined with further classification networks to speed up, automate, and standardise data collection from legacy resources, such as archaeological drawings and photographs in large unsorted PDF files. The AI-assisted workflow detects common objects found in archaeological catalogues, such as graves, skeletons, ceramics, ornaments, stone tools and maps, and spatially relates and analyses these objects on the page to extract real-life attributes, such as the size and orientation of a grave based on the north arrow and the scale. A graphical interface allows for and assists with manual validation. We demonstrate the benefits of this approach by collecting a range of shapes and numerical attributes from richly-illustrated archaeological catalogues, and benchmark it in a real-world experiment with ten users.

The science-fiction writer Robert Heinlein once wrote, "Each generation thinks it invented sex." He was presumably referring to the pride each generation takes in defining its own sexual practices and ethics. But his comment hit the mark in another sense: Every generation has to reinvent sex because the previous generation did a lousy job of teaching it. In the United States, the conversations we have with our children about sex are often awkward, limited, and brimming with euphemism. At school, if kids are lucky enough to live in a state that allows it, they'll get something like 10 total hours of sex education.1

Their meaning has been lost in ancient history but the distinctive marks on rocks by our ancestors thousands of years ago provide a unique link to our prehistoric past. Now a new project has been launched in an attempt to finally unravel some of the mysteries of the prehistoric rock art carved into stones in Scotland. Experts are to create a new digital database using 3D scanning to record and study more than 2,000 carvings across the country. Cup and ring marks are a form of prehistoric art found widely through out the world. They consist of a round indentation – the cup – surrounded by a series of concentric circles that look like ripples on water.
