On Earth, scientists are studying the most extreme environments to learn how life might exist under completely different settings, like on other planets. A University of Washington team has been studying the microbes found in “cryopegs,” trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures, which may be similar to environments on Mars or other planetary bodies farther from the sun.
At the recent AbSciCon meeting in Bellevue, Washington, researchers presented DNA sequencing and related results to show that brine samples from an Alaskan cryopeg isolated for tens of thousands of years contain thriving bacterial communities. The lifeforms are similar to those found in floating sea ice and in saltwater that flows from glaciers, but display some unique patterns.
“We study really old seawater trapped inside of permafrost for up to 50,000 years, to see how those bacterial communities have evolved over time,” said lead author Zachary Cooper, a UW doctoral student in oceanography.

The big picture: The new report suggests last year’s slowdown in renewable-energy construction has extended into 2019, taking the world in exactly the wrong direction at a critical time (see “Global renewables growth has stalled—and that’s terrible news”). Every major report finds that the world needs to radically accelerate the shift to clean energy to have any hope of not blowing past dangerous warming thresholds (see “At this rate, it’s going to take 400 years to transform the energy system”).

Investment in clean energy slipped to $117.6bn, a decline of 14 per cent compared with the same period last year, according to new research from Bloomberg New Energy Finance.
A sudden change in China’s renewable energy policies last year — when it curbed solar and wind subsidies — has dramatically reduced the number of new projects in the world’s largest market.
Clean energy investment in China was down 39 per cent during the first half of this year, compared with the same period last year.
However, those figures could improve later this year, suggested Justin Wu, BNEF’s head of Asia-Pacific.
