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.

Solar storms can consist of solar flares that are thrown out of the Sun, by the magnetic field. When the flare arrives at Earth, they can cause drastic effects, including throwing out radio communications and satellites, or even disturbing the power grid.
Experts have repeatedly warned that humanity might not be ready for the effects of a truly powerful solar storm, and that such an event could bring even deadly consequences.
To attempt to understand and mitigate the effects of any such storms, experts keenly watch the Sun and forecast space weather, in the same way they do weather on the Earth.
But existing systems are still hit by problems because of the complex characteristics of the Sun’s magnetic field, which make it very difficult to predict how it might behave.
Now scientists say they have established a new system that will work as an early warning system that can predict weather a solar flare will occur in the next two days.
The system uses neural networks – computer systems that are structured to work in a similar way to the human brain – to help identify characteristics that suggest a solar flare could be on its way.
The system works far more effectively than existing tools that aim to predict how the Sun might be behaving, write the team behind the breakthrough, who were led by Hong Chen from Huazhong Agricultural University in China.
The system is reported in a paper, ‘Two-Stage Solar Flare Forecasting Based on Convolutional Neural Networks’, published in the journal Space: Science and Technology.
