The new system of testing for doping in sport will have an "extremely deterrent" effect, world football body Fifa's chief medical officer has said.
Professor Jiri Dvorak said testers would now be able to freeze blood and urine samples so that scientists can re-test them later on, potentially using newer technologies to detect performance-enhancing drugs.
"There is a strong evidence that if you re-analyse the samples from past years that new methods would find them, this is an extremely deterrent method," he said.
"Most of the international federations decided to freeze the samples for a number of years.
Families of Hillsborough victims have described as "deeply upsetting" the revelation that insults relating to the disaster were reportedly posted online from Government offices.
Margaret Aspinall, from the Hillsborough Family Support Group, said: "I don't even know how to react, it's just so sad. I hear something like that and it upsets me a great deal, it makes me incredibly sad.
"I'm glad somebody has found out about it but I'm frightened to be honest that we haven't known until now."
Sheila Coleman, from the Hillsborough Justice Campaign, said: "We're still in the inquests and we've sat listening to the most heartbreaking accounts of that day, and then you hear about things like this. It's absolutely appalling, disgraceful."
A public spending watchdog has demanded action to speed up the Government's "frustratingly poor" record on removing from the UK foreign criminals who are costing taxpayers hundreds of millions of pounds.
Too many overseas inmates are still being locked up at public expense as the rate they are sent home has dropped by 14% over the past four years, the Commons Public Accounts Committee (PAC) said.
The committee's chair, Labour MP Margaret Hodge, said: "While more than 1,000 foreign national offenders are deported each quarter, a similar number are convicted, so the overall number of foreign national prisoners stays at the same level of around 11,000 - 13% of the total prison population."
"The agency should work with the Home Office to understand why there are delays in removing foreign national offenders, and tackle the barriers to their removal."
Around 500 wildlife areas could be at risk from the HS2 high speed rail line, conservationists have warned.
The Wildlife Trusts called for a £130m investment to create new green areas over the length of the new line.

Boris Johnson could continue as Mayor of London even if he becomes an MP in 2015, David Cameron has said.
"He obviously wants to complete his second term but I don't think it's impossible to do that and to put yourself forward as a member of Parliament at the next election," the Prime Minister said.
"As a manager, as it were, I want all my star players on the field and Boris is a star player."
It is thought Mr Johnson, who previously served as MP for Henley, may want to run for the North West Hampshire seat currently held by the Chief Whip, Sir George Young, who is stepping down next year.
Footballers at this summer's World Cup will be among the first athletes to face a new testing system designed to weed out doping in sport.
Under the new regime athletes will have blood and urine samples compared over time to create a 'biological passport' that tracks changes in their body over time.
Major sports federations, medics and doping experts agreed to the new system, which they hope will combat increasingly sophisticated doping techniques.
The Duke and Duchess of Cambridge were up before dawn for a solemn remembrance of Australia's war dead.
The couple made an unannounced appearance in the darkness at the Australian War Memorial in Canberra for the early service marking Anzac Day - a national day of remembrance for the nation's fallen, veterans and those still serving.
With the Australian War Memorial lit up behind them, William and Kate quietly arrived at around 5am local time on Friday.
Kate, 32, in a cream scarf and black coat and black leather gloves, stood to William's right, her hands clasped in front of her as they listened to the early readings which were already under way.
A new 'Claimant Commitment' setting out what jobseekers must do to find work in return for benefits have been successfully rolled out across the country.
The Department for Work and Pensions said the agreements had now been adopted in every UK jobcentre, with jobseekers agreeing to take steps to find work or face having their benefits docked.
Among the measures are registering to look for work through the universal jobmatch service or via a recruitment agency.
Jobseekers who fail to follow through with the commitment risk having their benefits docked.
