Everyone living and working in Liverpool - about half a million people - will be offered regular coronavirus tests in the UK's first mass testing of a whole city. The pilot scheme will start at the end of this week, and the armed forces will help carry it out. Liverpool has one of the highest rates of coronavirus deaths in England, and doctors at the city's intensive care units have told the BBC they're struggling to cope.
City Mayor Joe Anderson said mass testing could be "a game-changer", but our health correspondent James Gallagher points out there are questions about its efficacy. False positives could be a problem, as could individual behaviour - can authorities do better at persuading people who do test positive to isolate? The pilot will help authorities assess whether those sorts of issues can be overcome.
The clock, meanwhile, is ticking down towards the start of England's second nationwide lockdown. Plenty of sectors have been making last-minute arguments for an exemption, but at least one - children's grassroots sport - has been told it won't be granted. Retailers preparing to close their doors have also told us how they're feeling, and we've answered your questions on some of the finer detail, including what the restrictions mean for Remembrance Sunday.
Finally, Wales has been in lockdown for several weeks already - see how one community hub is helping those who've fallen on hard times due to the pandemic.

The most polarised US election campaign in decades has drawn to a close, with Donald Trump and Joe Biden taking part in their final rallies. Democrat challenger Mr Biden, alongside a few famous faces, urged voters to "take back" democracy, adding: "We're done with the tweets, the anger, the hate, the failure, the irresponsibility." President Trump packed in a punishing last-minute tour of crucial states, repeatedly attacking his rival's long record in politics. Look back on a wild campaign in three minutes.
The stakes couldn't be higher or the nation more divided, says our North America editor Jon Sopel. There's unease across the country, he adds, with shops and offices boarded up ahead of the result and workers told not to come in for fear of social unrest. The result might not be known for several days - this is why - only adding to the tension, but here are three headlines you might be waking up to on Wednesday.
Here's how to follow election night across the BBC and what to look out for when you do. Finally, check out our simple guide to how the whole thing works.

Police in Austria are still searching for at least one suspect after several gunmen opened fire at six different locations in the capital, Vienna, on Monday evening. Two people were killed and at least a dozen more wounded, some seriously. One suspect was shot dead by police and another arrested, officials said.
Austrian Chancellor Sebastian Kurz called it a "repulsive terror attack". The shootings took place near Vienna's central synagogue but it's not yet clear if that was the target. Leaders across Europe were quick to condemn the incident. Austria had until now been spared the sort of attacks that have hit other countries in the region.

The plan for mass Covid testing to be trialled in Liverpool makes the lead for many. The Daily Telegraph believes it could offer a "way out" of lockdown. "Covid hope" is the i's headline, while the front page of the Daily Express declares optimistically: "Virus battle will be done by Spring." Others, though, are not convinced by Boris Johnson's efforts to quell anger about England's looming second lockdown. The Daily Mail accuses him of "duping the public" by "cherry-picking only the most blood-curdling statistics" to regulate "who we hug, whether we visit our parents, and where we eat and drink". The Sun says banning children from playing sport outside is "simply inexplicable". The Financial Times feels the PM's attempts to remain upbeat have "failed to lift the gloom that has settled over the Tory party and among many business leaders". Elsewhere, actor Johnny Depp features widely after he lost his High Court libel battle. "Hollywood urged to ditch Depp" is the headline in the Times. Women's justice campaigner Harriet Wistrich tells the paper it would send "a terrible message" if he was allowed to continue making films.

From sexual liberation to the power-play of carers and benefit scams, BBC Four's CripTales presents a series of unexpected monologues written, performed and directed by disabled people. Elsewhere, turning a run into an adventure - a secret agent mission, for example - is just one of the ways the fitness industry is using technology to make working out more fun. Find out more.
