Marine microorganisms drive summer clouds over Southern Ocean

The Southern Ocean surrounding Antarctica is home to some of the most pristine air anywhere on Earth. And yet it’s also one of the cloudiest places on the planet, a seeming contradiction because water droplets require particulate matter in the air to condense into clouds. Now, a study looking at cloud droplet concentrations over the Southern Ocean is giving scientists a clearer understanding of the role played by marine microorganisms in cloud formation and climate.

Oil-encased water droplets are mini-ecosystems for microbes

Dark, sludgy oil may not seem like an environment suited to life. But microbes, known to make meals of such organic stews by breaking down large hydrocarbons to extract food and energy, have been found before in petroleum reservoirs. Now, in a new study, researchers report finding diverse communities of microorganisms living inside tiny water droplets in Pitch Lake, the world’s largest natural asphalt seep located on the Caribbean island of Trinidad. The discovery may have implications for industry, scientists say, as well as for our understanding of extreme life.

Bacteria back from the brink

Thousand- and million-year-old microbes found living in salt crystals:  Could they also exist on other planets?

In 1993, “Jurassic Park” thrilled the world with the idea that dinosaurs could be resurrected from bits of DNA preserved in mosquitoes trapped in ancient amber. In the 18 years since the movie came out, scientists have been finding that parts of this scenario are closer to reality than anyone ever imagined.
