From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

The tiny, single-cell organism discovered by researchers in Sydney, Australia has the capacity to naturally absorb carbon and can photosynthesise, hunt, and eat. It is plentiful in marine environments around the world.
“This could be a game-changer in the way we think about carbon and the way it moves in the marine environment,” the study’s senior author Martina Doblin told Newsweek.
The existence of the marine microbe suggests to scientists that the ocean has a greater capacity to absorb and store carbon than is currently believed.
The potentially important marine microbe in question operates by secreting a mucus-like substance called “exopolymer mucosphere,” rich in carbon, that then traps other microbes. After consuming some of the trapped prey, the microbe ejects the substance — which sinks back down into the ocean’s carbon-cycling system.
It is the potential to move carbon from the ocean’s surface to deep within the ocean that could be particularly useful in regulating the climate. Researchers have estimated that the newly-discovered microbe species could sink up to 0.15 gigatons of carbon each year.
This potential new species will not likely solve the world’s climate problems on its own.
Scientists believe that the world needs to remove 10 gigatons of carbon from the atmosphere yearly to prevent catastrophic global warming; this microbial species, at best, could help remove just over 1 percent of that goal.
But researchers are hopeful that there may be similar marine microbial species that could help with carbon sequestration as well.
“The implication is that there’s potentially more carbon sinking in the ocean than we currently think and that there is perhaps greater potential for the ocean to capture more carbon naturally through this process, in places that weren’t thought to be potential carbon sequestration locations,” Ms Doblin told Newsweek.
