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.
Your support makes all the difference.Cigarettes can make the lungs "leaky," causing far more damage than high levels of air pollution, researchers said yesterday.
Smoking cigarettes was found to cause a big increase in the "leakiness" of the lungs, reducing the efficiency of oxygen transport. However, no such increase was observed when healthy people were exposed to concentrated levels of ozone - a common air pollutant caused by vehicle exhaust fumes, the British Lung Foundation study found. The new research carried out at the Respiratory Medicine Unit at Edinburgh University is the first to compare the direct effects of tobacco smoke and ozone on the lungs.
