Electricity-driven undersea reactions may have been important for the emergence of life

By     No comments:
In deep sea hydrothermal vents, water heated by Earth's mantle flows into the ocean, precipitating various minerals, including metal sulfides. These minerals form channels for the vent water, and since the metal sulfides are electrically conductive and the vent and ocean water are compositionally different, an electric current is created. ELSI scientists have shown this current can reduce metal sulfides to metals, which can reduce organic compounds. These reactions could have helped jump-start life's chemistry.

The reduction was even greater (50%) in those who had close friends who smoked when they were 16.

The geoengineering of consent: How conspiracists dominate YouTube climate science content

By     No comments:
Using YouTube to learn about climate-change-related topics will expose you to video content that mostly opposes worldwide scientific consensus. That's the finding of a new study, which also reveals that conspiracy theorists have 'hijacked' some scientific terms, such as 'geoengineering,' so that searches provide entirely non-scientific content. Scientists could counteract this by forming alliances with influential YouTubers, politicians and those in popular culture, to ensure scientifically accurate video content reaches the widest-possible audience.
