Ancient Antarctica was a warm swampy rainforest, says sediment study


It’s hard to imagine Antarctica as anything other than a freezing lifeless landscape, but that wasn’t always the case. Now, an international team has recovered a 90-million-year old soil sample that paints the most detailed picture of ancient Antarctica ever found, revealing a swampy rainforest and balmy temperatures.

According to the study, during the peak of the Age of the Dinosaurs, West Antarctica was covered in dense vegetation, rivers and swamps. The annual average air temperature was around 12 °C (53.6 °F), and during summer that average went up to a pleasant 19 °C (66.2 °F). Rainfall amounts and intensity were similar to the lowlands of places like Wales.

The Deepest Hole in the World


For 24 years, Soviet scientists dug deeper into the Earth’s surface than anyone had ever done before. The result was the Kola Superdeep Borehole located on the Kola Peninsula in Russia.

The ambitious project began in the 1970s, and scientists in the former Soviet Union began to drill a hole that was just 9-inches in diameter. The hole eventually extended 7.5 miles into the Earth’s crust, farther than the deepest point in the ocean, Challenger Deep in the Marianas Trench in the Pacific Ocean at 6.8 miles.

What did the scientists learn, and what did they find at these incredible depths? Quite a lot actually. They found single-celled plankton organisms at 4.3 miles down, and at nearly the same depth they discovered water. They also discovered that the temperature reached 356° F at the bottom of the hole which was more than their estimates. This became the reason the hole had to be eventually abandoned in 1994. The hole was simply too hot for drilling to continue. The environment became more liquid because of the hot conditions, and the borehole was increasingly more difficult to maintain. Plus it ruined equipment quickly.

5 Strange Wonders of the Natural World


The natural world is full of beauty, wonder, and weirdness. Some aspects of nature, like seemingly impossible land formations or peculiar flora, are so bizarre that science is still working to explain exactly what they are and how they came to be. Some things are so strange that researchers believe it could only have been man-made…despite a complete lack of evidence to explain its existence either way.

USF researchers find human-driven pollution alters the environment even underground


The Monte Conca cave system on the island of Sicily is a vast system of springs and pools, sitting below a nature preserve. It might be presumed to be one of the few places untouched by human-driven pollution.

But new research published by a USF microbiology and geoscience team has found that even below ground, the microbial communities in the pools of water in the Monte Conca cave show signs of being altered by pollution from above.

Will this make us more susceptible to the solar wind and increase the chances of being hit with meteorites?

Nothing can change the chances of being hit by a meteorite, however solar wind would be able to do some damage if the change is big enough.
