SINGAPORE: Minister for Social and Family Development Chan Chun Sing said he does not welcome Ashley Madison, a dating website targeting married spouses, into Singapore.
Posting on his Facebook page on Friday, Mr Chan said he is against any company or website that harms marriage.
"Promoting infidelity undermines trust and commitment between a husband and wife, which are core to marriage," said Mr Chan, who is also second minister for defence.
"I'm heartened by the responses of many Singaporeans who also spoke up against such website," he added.
Mr Chan's comments followed reports that Ashley Madison plans to expand into Singapore next year.
The website, which touts itself as "the famous name in infidelity and married dating", and has a tagline "Life is Short. Have an Affair," has a presence in the US, Europe and a number of other places, including Hong Kong and Japan.
News of its plans for Singapore prompted strong responses, including the formation of a Facebook group called “Block Ashley Madison” that has garnered over 11,000 likes.
In a statement, the Media Development Authority (MDA) said its content regulatory framework is based on community standards and social norms.
A spokesperson said since there are growing public sentiments against the site, it will take these into account when evaluating the website, if it is set up.
Under the Broadcasting Act, MDA has the powers to act against Internet content providers which violate community standards and social norms.
This includes issuing take-down notices or site-blocking.

Carnivorous killer algae found in Danish waters
Carnivorous killer algae found in Danish waters
May 8, 2012 - 06:27
We know that fish eat plankton and plankton eat algae. Think again, says researcher, who has spotted a form of algae so ferocious that can they overpower animals 10,000 times their own size.

Algae are a vital part of the life cycle. They are the food source for larger zooplankton such as copepods, which are eaten by fish larvae, so they can grow to become the fish we see on our dinner tables.
But apparently it works the other way round too. There are actually algae that are the ocean equivalent of carnivorous plants.
This is the startling conclusion from biology post doc Terje Berge, the leading author of a brand new study, which has just been published in the scientific journal International Society for Microbial Ecology (ISME) Journal.
When the grass eats the gazelle
“What’s really quite sensational about this discovery is that algae, which appear to be animal and plant at the same time, attack and eat zooplankton,” says Berge.“If we imagine an African savannah, this would roughly correspond to the grass suddenly jumping up, attacking and starting to eat the gazelle.”

The alga, which goes by the latin name Karlodinium armiger, has so far only been found on the Spanish coast, where it is suspected of having caused extensive fish die-offs in the region. ‘Armiger’ is latin for ‘The armed’.
Now Berge has discovered that this kind of combative algae also exists in Danish waters.
Studying the hungry algae under a microscope has provided Berge’s team with a clear answer to how algae can turn into carnivores. Their eating sprees offer a tremendous insight into the world of biology.
Killer algae suck the life out of their prey
First, the algae locate their prey by sensing their chemical traces in the water. Then the algae kill the animal – and the animal’s size is of little importance. Sometimes the prey can be up to 10,000 times larger than the algae themselves.This, according to the new study, means that the algae are capable of eating animals the size of copepods or perhaps even fish larvae.
If we imagine an African savannah, this would roughly correspond to the grass suddenly jumping up, attacking and starting to eat the gazelle.
The algae then start eating from the still living animal by poking holes into it and sucking the nutrients out of it through a kind of straw – much like mosquitoes do with us humans.
When the algae conspire, they are deadly. As soon as the nutrients start to seep out of the animal, the nearby algae are triggered, and before long they form a giant swarm around the attacked animal.
As the prey is being consumed, the algae start growing – now they grow not only through photosynthesis like other algae, but also from the nutrients from the animal they’re eating.
The food chain can go both ways
As long as the algae don’t attract too many of its co-combatants, there is no danger – the animals just eat the algae.Facts
When algae don’t eat, they usually survive by means of photosynthesis, which sends light, CO2, nutrients and water to all of the algae’s building blocks.Algae create oxygen through photosynthesis – in fact, algae are responsible for almost half of the world’s oxygen production.
On the east coast of Spain, scientists have found concentrations of between 10 and 100,000 algae per millimetre. These high concentrations have yet to be observed in Scandinavian waters, but the new discovery is likely to explain why the growth of algae related to Karlodinium is being associated with fish die-offs in Scandinavian countries too.
Carnivorous algae have grave consequences
Berge is keen to stress that the algae pose no particular threat to humans. But the discovery plays an important role in our understanding of how nature works.”It’s remarkable that the algae can turn the food chain around this way,” he says. “And they don’t do it just by spreading poison, but simply by hunting – it’s a completely new perspective on what algae are capable of.”
There are isolated examples of other microscopic animals that can attack animals further up the food chain. But unlike with the carnivorous algae, this doesn’t have any serious consequences, such as extensive fish die-offs.
Berge and his colleagues will now try to learn more about how strong the algae poison is. The stronger the poison, the larger the animals the algae can kill when they band together.
In the novel and the movie "Life of Pi",Pi encountered a floating island of carnivorous algae that is inhabited by meerkats while shipwrecked somwhere in the Pacific Ocean. I was curious if there is such thing as carnivorous algae and decided to find out. In fact, there are people posted in different forums asking if there is such thing as carnivorous algae. No, I was not interested what the island signified. It turned out there is such .....
