7 Dec Today, the amount of carbon dioxide humans are pumping into Earth's atmosphere is threatening to skew the accuracy of this technique for future archaeologists looking at our own time. That's because fossil fuels can shift the radiocarbon age of new organic materials today, making them hard to distinguish . Any charcoal or wood sample that is carbon dated will have an apparent age. The "old wood" effect should be taken into account to avoid wrong conclusions when linking materials to event and context. 9 Sep Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so - a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.

Would you say there's a time in a strictly monogamous relationship where you don't need to use protection anymore (because of STIs, not for birth control, I mean)

I would love to see a full and comprehensive episode on sex shaming. Definitely on slut shaming women and the like, but also on the destructive assumptions of male sexuality, like how it's all we think about, or that if we get a hard-on then we're being pervvy or even consenting to sex regardless of what we're saying. There's a lot of male sexuality shaming myths in the public that rarely gets talked about.
