The papers: Gerry Adams' release and meditation in the City
The story which dominates Monday's papers is the Sinn Fein leader Gerry Adams' release from four days of police custody. He was being questioned over the murder of Belfast mother-of-10 Jean McConville in 1972.
Mr Adams, who maintains he had nothing to do with Mrs McConville's death, has stressed his party "remains wedded" to the Northern Ireland peace process, the Guardian reports.
The measured tone of Mr Adams' statement on his release was echoed by shadow Northern Ireland secretary Ivan Lewis, who said: "Wise and cool heads are needed amongst leaders on all sides", the paper says.
Helen McKendry, a daughter of the murdered woman, is quoted by the paper as saying if formal charges are not forthcoming, the family has received cash backing from a donor to launch a civil action against Mr Adams.
The Daily Telegraph says the Sinn Fein leader is calling "the Boston tapes" - the American academic research project said to implicate him in the murder - "discredited and relied upon hearsay".
Anthony McIntyre - a former IRA member whose research project for Boston College collected the testimony - is said to be "living in fear", the Daily Mail says.
It says threatening graffiti about Mr McIntyre has appeared in Belfast. He says Boston College did not do enough to keep the tapes out of the hands of the British state.
The Independent highlights Mr Adams' description of his arrest as "malicious and sinister".
The paper says Sinn Fein is claiming the move was motivated by "an embittered rump of police officers" who wanted to "settle old scores".
The Sun provides two alternative voices on the arrest: Jim Gamble, a former RUC anti-terror chief, says political leaders in Northern Ireland must give police "the benefit of the doubt, to trust they will see lawful, balanced and appropriate policing".
Kevin Toolis, a writer on the Troubles, says: "It was always going to be safer to let sleeping IRA dogs lie."
Writing in the Times, Melanie Phillips accuses Sinn Fein of adopting the language of "continuing war".
She adds that if "justice is denied for wrongs that have been committed, a worm of corruption continues to eat at society's soul".
There have been many contentious corporate takeovers in history, but US firm Pfizer's bid for British pharmaceutical company AstraZeneca does seem particularly bitter.
The Financial Times reports on the growing political involvement in the affair, saying that David Cameron has been accused of "pushing" Pfizer's offer.
The charge comes from Labour leader Ed Miliband who argues for "a stronger public interest test" before foreign takeovers are allowed, the paper adds.
The Daily Mirror's Kevin Maguire agrees with this stance.
He states "putting Britain up for sale is a bigger threat to our nation's jobs, prosperity and sovereignty than any European Union directive".
The Guardian says Labour's approach has caused a "coalition rift" with Lib Dem Business Secretary Vince Cable guardedly welcoming Labour's idea, but Tory party chairman Grant Shapps saying the plan is "anti-business".
The paper's leader column says Mr Shapps' intervention has made him a "comical figure" .
However, the Daily Telegraph's opinion column rejects the Labour plan, saying "the market is wiser than Ed Miliband".
The Times reports that AstraZeneca will defend itself from further bids from Pfizer by setting out details of new drugs it is developing in the hope that this will persuade shareholders to resist the lure of immediate cash.
The paper's business section says AstraZeneca (which employs 9,000 scientists) has 11 treatments in late-stage trials and 19 others expected to arrive this year.
A boom in the building of new houses has gripped the country, the Daily Telegraph reports.
The paper says 5,000 new housing estates have been approved since planning laws were relaxed two years ago, and applications have shot up by 10% to 200,000.
It says house-building will become a "key issue" in this month's local elections, especially in rural areas, where many of the new builds have sprung up.
It quotes Lord Wolfson - described as a key member of "George Osborne's inner circle" - as saying "unloved, flat, ecologically unimportant land... should be considered for housing".
Ranged against Lord Wolfson's views are campaigners such as Susan Parker, of Guildford Greenbelt Group.
The paper says her view is that "growth does not have to come from building".
The Daily Mail reports on a scheme to be announced this week that seems likely to encourage the building boom.
It says a new "right to build" rule will force councils to make land available to people who want to build their own homes, providing they have lived in the area for three years.
The paper says the scheme is a "radical plan" and will be a "key part" of Conservative policy going into the next election.
The housing demand is shown by another article in the Mail which says parents are risking their financial future to help their children buy homes.
It says nearly 40% of parents have helped their adult children buy a home, and assets used include their own pension pots.
The figure is based on research from the Halifax.
It seems Count Dracula may have been on to something, according to a story carried by many papers.
The Daily Telegraph is among many publications to report that injections of blood from young people could reverse the ageing process in the older population.
The paper quotes one Harvard University scientist involved in the research as saying: "This should give us all hope for a healthy future".
The Times says the young blood infusion idea does not have a successful history to it.
It recalls that in the 1400s Pope Innocent VIII was treated with the blood of three young boys as he lay mortally ill. Both the pontiff and the young donors died, it says.
The Daily Express focuses on hopes that the treatment - which is still at an early development stage - could "rejuvenate dementia patients".
But it also notes that an Alzheimer's Research UK spokesman says the research, "while very interesting", does not investigate the type of brain function impairment seen in Alzheimer's.
The condition affects half a million people in the UK.
The Guardian reports on how the infusion of young blood plasma benefitted elderly mice. An aged mouse is one aged 18 months or older.
The paper says after the blood treatment the venerable rodents found their way around mazes as well as mice a third of their age.
The Daily Mail reports that old mice's fading sense of smell was also sharpened by the treatment.
It says in future a pill could give humans a similar treatment.
When do you feel most happy? If it is at 6:08pm on Friday you are perfectly average, the Daily Telegraph reports.
The paper publishes research from Citizens Advice that found that the happiest time of the week was, not surprisingly, just moments after most of us have knocked off work for the weekend.
Conversely Monday lunchtime - 1:42pm to be precise - is where people's employment-related ire reaches "fever pitch", the paper adds.
Citizens Advice say its website sags under the demand of the many fed-up workers who consult its employment rights section during their midday break on Monday.
Perhaps they need a bit of "mindfulness" - as reported in the Financial Times.
The paper says this ancient Buddhist concept is currently "gripping the City of London".
Financiers, it reckons, are turning to this combination of meditation and breathing techniques to bring them "greater clarity of thought in a world dominated by technology".
The FT doesn't go as far as to explain how mindfulness can be practised, but it does quote a Goldman Sachs manager who says: "In years to come, we'll be talking about mindfulness as we talk about exercise now."
But on the other hand, perhaps happiness can just come from a tin, if a story in the Daily Mail can be believed.
It says a Tasmanian study has suggested that eating tuna can cut the risk of depression by 25%.
But guys rushing for a can opener can hold fire, as the research suggests the effect is only seen in women.
The high levels of omega-3 in the fish could combine with oestrogen to create a feeling of well-being, the paper suggests.
