I love it when news lines up almost perfectly with our editorial calendar. Next week, I've got a Science Question from a Toddler feature lined up that will explain how scientists can date reserves of water, and what makes ancient water special.
This week, in Antarctica, a team of Russian scientists made contact with some very ancient water. Yesterday, they drilled through the last of a more than 12,000-foot ice cover and into Lake Vostok, a reserve of liquid water that hasn't had contact with the outside world in 15-34 million years.
These researchers are looking for extremophile bacteria—semi-alien Earthlings that have evolved separately from the rest of their terrestrial kin. Bryan Walsh at Time.com explains:
The hope is that some form of new microbial life might exist within the waters of the lake, which remain liquid despite the cold thanks to heat generated by the pressure of all that ice and geothermal energy rising from the planet’s core. The environment of Lake Vostok is similar to that found on Jupiter’s icy moon of Europa. If life can survive in Lake Vostok, it might just be able to survive on another planetary body.
It’s still going to take the Russian scientists some time to actually take samples from the lake—with the Antarctic winter on its way, they’ll need to leave Vostok Station soon. And there are environmental concerns that the drilling process could contaminate the lake, which is pristine. The researchers used more than 66 tons (60 metric tons) of lubricants and antifreeze in the drilling process—chemicals that would have polluted Lake Vostok had they leaked through the ice, and contaminated any samples. The good news is that contamination seems to have been avoided: the scientists plugged the bottom of the bore hole with Freon, an inert fluid, and drilled the final distance to the lake surface using a heated drill tip instead of a motorized drill that needed chemical lubricants. When the lake was breached, water flowed up the bore hole before freezing and forming an icy plug.

A trio of scholars who study the psychology and philosophy of science have written a fantastic paper for Springer’s Sythese looking at the way that climate change conspiracy theorists construct their view of the world, and how these conspiracy theories contain self-contradictory theses (like the idea that climate change can’t be predicted and the idea […]
Princeton University psych prof Susan Fiske published an open letter denouncing the practice of using social media to call out statistical errors in psychology research, describing the people who do this as “terrorists” and arguing that this was toxic because of the structure of social science scholarship, having an outsized effect on careers.
