The orange, purple and green cauliflowers that scientists claim could be healthier for you

Cauliflower cheese will never be the same again.

Scientists have developed amazing variants of vegetable where the traditional white florets have been changed to a garish orange, purple and green.

The "rainbow cauliflowers" are said to taste the same as the normal varieties, but add a splash of colour to the dinner table.

Some scientists have even claimed that they are healthier for you.

Andrew Coker, a spokesman for the plant company Syngenta - which is developing the plants in Europe - stressed that the colourful cauliflowers were not the result of genetic engineering, but came after decades of traditional selective breeding.

Cauli-ful: The green, orange and purple varieties of cauliflower

Although its not the first time that orange and green cauliflowers have been seen in Britain, their creators say they will be the first to be commercially available in supermarkets and markets.

They retain their colour even after cooking. "The pictures may look garish, but they are really are this colourful," said Mr Coker.

"Consumers are looking for ever new experiences on their dinner plates and colour features very large in their desire for different things.

"These are the results of traditional selective breeding - where different strains have been cross breed and cross bred until these strains have been created.

"We are now trying to ensure that we have the consistency of colour, taste and size before bringing them to the mass market. But you will find them in smaller outlets from this year."

In tests, the garish cauliflowers have proved a hit with shoppers.

While traditionalists may baulk at the unusual colours, it is not the first time that plant breeders have changed the appearance of vegetables.

Until the 17th century most carrots eaten Europe were white, yellow or purple. The orange pigment was added by Dutch plant breeders looking for a way to celebrate Holland's royal family.

The last few years has seen the introduction of purple carrots to supermarkets in Britain, along with yellow tomatoes and purple potatoes.

In America, where colour cauliflowers have been available for several years, they have been a big hit with foodies. The orange cauliflower has higher than normal levels of beta carotene, a form of vitamin A that encourages healthy skin.

The purple colour comes from anthocyanin, which may help prevent heart disease by slowing blood clotting.

Tests of the orange cauliflowers in America found that they contained 25 times the concentrations of beta carotene in normal cauliflowers.

Count Cards

Be warned that this picture is inaccurate. 1+1+1+1 equals +4, not +2.(Now CORRECTED)

Statistically speaking, you are doomed to lose at every game on the casino floor — unless, that is, you can count cards. At the blackjack table, speedy math skills can flip the advantage from the house to you. Granted, it's a small edge — 2 percent at best, which is nowhere near as good as dragging Rain Man to Vegas. But what have you got to lose? (Oh, yeah, all that money.)

Bring mucho moola. Your edge will come from betting more when the dealer's shoe — a device for holding multiple decks of cards — is rich with big cards, which tend to help you and hurt the house. Success takes time and a bankroll of at least 400 times your standard bet.

Count and cancel. Using the classic Hi-Lo method, you start with zero at the shuffle. For every 10, face card, or ace that hits the table, subtract a point. For every 2 through 6 card, add a point (the 7, 8, and 9 cards = zero points). When possible, let cards cancel each other out to save time.

Divide and bet. Before each hand, divide your count by the estimated number of decks left in the shoe (tip: guess how many decks are in the discard stack and subtract that amount from the total number used in the game — usually six). When the result hits +2, bet like a big dog.

Be inconspicuous. Don't move your lips as you calculate. Or bet too many chips. Counting cards isn't against the law, but a suspicious pit boss will show you the door — or just signal the dealer to shuffle, which wipes out your boosted odds and sets the count back to zero. D'oh!

Learn basic strategy. Basic strategy is a mathematically calculated optimum way to play your hand in every situation. There are variations in strategy according to the number of decks used and the different blackjack rules. A perfect basic strategy player plays at almost no disadvantage to the house.

Learn deviations. A deviation is a change from basic strategy by playing the hand differently according to the true count. There are many deviations, but start by learning the "illustrious 18", that should get you started.

Facebook can ruin your life. And so can MySpace, Bebo...

People will post just about anything on social networking sites. And the information can be used against them. David Randall and Victoria Richards report

In the judicial backwater of a New Jersey federal court, a case is being heard that nominally affects two families but should also make millions of Britons think twice about something they do every day: put highly personal information on Facebook, MySpace or Bebo.

An American insurance company, in defending its refusal to pay out a claim, is seeking to call in evidence personal online postings, including the contents of any MySpace or Facebook pages the litigants may have, to see if their eating disorders might have "emotional causes". And the case is far from a lone one. Suddenly, those saucy pictures and intimate confessions on social networking sites can be taken down and used in evidence against you in ways never dreamed of.

In the US, a sex assault victim seeking compensation faces the prospect of her MySpace and Facebook pages being produced in court. In Texas, a driver whose car was involved in a fatal accident found his MySpace postings ("I'm not an alcoholic, I'm a drunkaholic") part of the prosecution's case. From Los Angeles to Lowestoft, thousands of social network site users have lost their jobs – or failed to clinch new ones – because of their pages' contents. Police, colleges and schools are monitoring MySpace and Facebook pages for what they deem to be "inappropriate" content. Online security holes and users' naivety are combining to cause privacy breaches and identity thefts. And what all this, and more, adds up to is this: online social networking can seriously damage your life.

Just ask the 27 workers at the Automobile Club of Southern California fired for messages about colleagues on their MySpace sites; the Florida sheriff's deputy whose MySpace page revealed his heavy drinking and fascination with female breasts – and swiftly found himself handing in his badge; the Argos worker in Wokingham fired for saying on Facebook that working at the firm was "shit"; the Las Vegas teacher at a Catholic school fired after he declared himself gay on his MySpace page; the staff of an Ottawa grocery chain fired for their "negative comments" on Facebook; the 19 Northampton police officers investigated for Facebook comments; and Kevin Colvin, an intern at Anglo Irish Bank, who told his employers he had a family emergency, but whose Facebook page revealed he had, in reality, been cavorting in drag at a Hallowe'en party.

What these and other cases show is that employers and authorities are now monitoring what people imagined were private websites – and using the contents against them. Last September, David Rice, Britain's second-ranked tennis junior, and Naomi Brady, national U-18 champion, had their funding pulled and coaching suspended after the Lawn Tennis Association found pictures of them drinking beer, partying and, in Ms Brady's case, posing at a nightclub with her legs wrapped around a vending machine. And last summer, Oxford University proctors disciplined students after pictures of them dousing each other in shaving foam, flour and silly string in post-exam revelry were found on their Facebook pages.

At Cambridge, at least one don has admitted "discreetly" scanning applicants' pages – a practice now widespread in job recruitment. A survey released by Viadeo said that 62 per cent of British employers now check the Facebook, MySpace or Bebo pages of some applicants, and that a quarter had rejected candidates as a result. Reasons given by employers included concerns about "excess alcohol abuse", ethics and job "disrespect".

Viadeo's UK country manager, Peter Cunningham, said the results should act as a wake-up call to anyone who has ever posted personal information online. "Millions of people are leaving personal information online, much of which is cached and remains available via search engines even after the author has removed the web page," he said. "When people who are not the original intended audience – such as potential employers – find this information, it can have a major impact on their decision making process."

In America, the monitoring of social networking sites for content that may interest employers and officialdom is now so routine that software is being put on the market that will automate the process. Sure enough, software to try to defeat the snoops is also emerging – offering the prospect of a privacy "arms race" in the years ahead. ReputationDefender, for instance, offers the embarrassing personal information equivalent of credit reports, claiming it can help expunge from the online record material you regret revealing. Michael Fertik, the firm's CEO, said demand for their service is now "ridiculous", with hundreds of UK clients already.

He said: "Young people today do the same thing they have always done on paper, but now they do it on a web page... The first thing we do is lobby those involved and, quite simply, ask them to remove the material by going first to the individual, then to the moderator or administrator, then, if necessary, to the ombudsman or ISP controller."

What he and other experts emphasise is the online innocence of many social network site users. Privacy specialist William Malcolm of Pinsent Masons law firm said: "Rather than looking at what information constitutes a risk, it's better to think, 'Who am I sharing this information with?' If you're not sure about the identity of a third party on the website then you have to ask yourself if you would do that in an offline context, and the answer is that you probably wouldn't."

Few people bother to read the fine print of a social network site's agreement, and the consequences of using one can occur in the most unexpected ways. A Newport Pagnell man, for instance, was ordered by magistrates not to contact his estranged wife, but when he joined Facebook, an automatic "friend request" was sent to everyone on his email list, including his former partner. She contacted police; the man was arrested and got 10 days in jail.

The first Facebook or Bebo divorce case cannot be far away. Divorce specialist Elizabeth Allen, head of family law at Stephens and Scown, Exeter, said: "Social networking has much more scope for trouble because of the public element. It's got the potential to be more explosive. It's just like airing your dirty laundry. We've had divorces that have been due to Friends Reunited in the past and that will be replaced by Facebook with the next generation. Now most people who would never have written a love letter to someone are writing it all down and sending it because they somehow think it's different."

As well as unwise posting of content, there is also an unknown but large number of people whose privacy has been compromised, or their identities stolen, as a result of their own naivety combined with the security vulnerability of the social network sites, and the willingness of others to exploit that. Last month, for example, a hacker downloaded half a million private pictures from MySpace and made them available on the file-sharing site BitTorrent.

Although MySpace, Facebook and Bebo do what they can to maintain the privacy of their users, there is a constant stream of security breaches related to the applications placed on the sites. These number in the tens of thousands, most of which have been devised not by corporations, but individuals. Virtually all of them require a user to sign away various bits of personal information in return for getting the application, and, to begin work, all an identity thief needs is a name, address, date of birth, and a pet's, parent's or sibling's name. And the use of social network pages to perpetrate serious sexual or anti-personal crime is well known. Virtually every week a sexual predator is found to have used MySpace or Facebook pages to groom young girls.

That something as ubiquitous as social network sites (they have 13.7 million UK users) are exploited by paedophiles and other serious criminals is not surprising. Happily, the numbers affected are small. But the use of personal page content in civil disputes, divorces, employment and legal actions will affect far more of the millions now innocently sharing their thoughts and intimate moments with the online world.

A Facebook spokesperson said: "We may be required to disclose user information pursuant to lawful requests, such as subpoenas or court orders, or in compliance with applicable laws. We do not reveal information until we have a good-faith belief that an information request by law enforcement or private litigants meets applicable legal standards."

In the New Jersey insurance case, involving Horizon Blue Cross Blue Shield, judges have yet to decide if they will allow the use of online postings to outweigh privacy rights. But many think it only a matter of time before such evidence is routine. Vanessa Barnett, ecommerce lawyer with Berwin Leighton & Paisner, said: "I have come across it in the recruitment field where employers are trying to form behind-the-scenes information on candidates. It doesn't surprise me that they're doing it and it wouldn't surprise me to learn that insurance companies in the UK are doing it either."

Social network sites have brought unexpected pleasure to millions. But if present trends continue and users fail to wise up, the sites could soon be bringing them some equally unexpected shocks.
