Several of the papers lead on what the Daily Mail describes as "the best heart drug since statins".
Scientists are said to have found that a new drug, given by injection every three months, can cut the risk of heart attacks by a quarter.
It is called Canakinumab and works by reducing inflammation.
The Sun calls it a "wonder drug" that "slashes the risk" of cancer too.
The i newspaper hails the dawn of "a new era in heart disease treatment" but says the price will have to come down before it can be approved.
The Times says the drug currently costs £40,000 per patient per year as an arthritis treatment - so that could delay widespread use of the medicine alongside statins as a heart treatment.
According to the Guardian, Jeremy Corbyn is facing a backlash from senior MPs in Labour's heartlands because of the party's "shift to soft Brexit".
Three of them, from the Midlands and northern England, have told the paper that the move risks alienating thousands of voters in traditional seats who support greater controls on immigration.
The Financial Times says Labour's announcement is putting Theresa May under renewed pressure from her own party over Brexit.
Pro-European Conservatives, the paper says, will be emboldened to urge the prime minister to accept a softer deal.
One unnamed senior pro-remain Tory is quoted as saying: "The leverage among soft-Brexit Tories has increased significantly".
The Times leads on the case of a white, Christian five-year-old girl who, it says, has been taken from her family and forced to live with a foster carer who wears a niqab.
In an internal report seen by the Times, a supervisor at Tower Hamlets council in London describes the child sobbing and begging not to be sent back to the foster carer's home because "they don't speak English".
The council put out a statement saying: "All our foster carers receive training and support from the council to ensure they are fully qualified to meet the needs of the children in their care."
"Charles must be our king" is the bold message spelt out in a purple box on the front of the Sun, pointing to an article inside by the paper's famed royal photographer, Arthur Edwards.
He has decided to speak out after a recent poll suggested 51% want Prince William to be the next monarch.
Edwards disagrees: "The monarchy doesn't work like that. It's not an X Factor vote. Charles will be our next king, it's his birthright."
The photographer says his job has given him a unique insight into Charles's mindset - he's educated, passionate and very bright, has been heir for 65 years - and will be a good king.
Finally, back to Brexit and the Daily Express reports a surge in vacuum cleaner sales as shoppers rush to beat an EU ban on the most powerful models.
"Buy now while stocks last", the paper says.
"It is a British person's inalienable right to have a vacuum cleaner of such ferocity that it sucks up your underlay and your floorboards."
