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.
At Blue Hill, Maine’s George Stevens Academy, there lies a Twinkie that was the subject of teacher Roger Bennatti’s 1976 science lesson on chemical preservatives and shelf life. Now the immortal snack cake sits in a glass case on the desk of the school’s Dean of Students Libby Rosemeier who was a student in the […]
In the early 1970s, Princeton University physicist Gerard O’Neill became a space activist touting plans to build human colonies in outer space. He argued that humans could escape (while helping alleviate) the environmental damage we are causing on Earth by migrating to space habitats housed in cylinders that would be suspended 250,000 miles from Earth […]
In a new scientific study, McGill University researcher Jay Olson combined stage magic with psychology to make people think that an fMRI machine (actually a fake) could read their minds and implant thoughts in their heads. Essentially, Olson and his colleagues used “mentalist” gimmicks to do the ESP and “thought insertion” but convinced the subjects […]
If you’ve got a coding career on your mind, few programming disciplines will take you farther than a commanding knowledge of the Python language, which is not to be mistaken for parseltongue. Its versatility and ease of use make it a go-to for any coding project…so master Python now with this all-inclusive all-level python programming course […]
