New possibilities for life at the bottom of Earth"s ocean, and perhaps in oceans on other planets
In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life. These vents belch scorching hot fluids into extremely cold seawater, creating the chemical forces necessary for the small.....»»

"The nastiest soils on Earth" are getting recognized as a bigger problem
Acid sulfate soils are characterized by their orange hue and their tendency to kill surrounding vegetation and fish. Anders Johnson's extensive research along Sweden's coastline reveals the widespread presence of these soils, underscoring their signi.....»»
Decades after global regulations, the Arctic Ocean"s legacy persistent organic pollutants haven"t dropped
The presence of persistent organic pollutants (POPs) in all the world's oceans but one has been in steady decline since 2001, when 152 countries agreed on a comprehensive global ban. The exception has been the Arctic Ocean, which has seen a sharp ris.....»»

Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
How many additional exoplanets are in known systems?
One thing we've learned in recent decades is that exoplanets are surprisingly common. So far, we've confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets were discovered using the transit method. though there.....»»
Earth underwent a massive, rapid melting period after the last global ice age, new study suggests
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—other.....»»
