Researchers in the United States have warned that it could take a decade for a vaccine againstthe Zika virus to be made available. Scientists at the University of Texas say most of the timewill be taken up in securing regulatory approval. They say the mosquito-borne virus has beenlinked with impaired brain development in the womb. Dr. Mark is the Head of the Pan AmericanHealth Organisation.
The priority is to aggressively control the vehicle. This is not Ebola. This virus needs avehicle to be transmitted. And it's a mosquito. If countries pick up the garbage, if countries areeducating people about covering the waters, the containers, because that's where themosquitoes breed, then they may be able to minimize massively the impact of this virus inwomen.
Reports from Sweden say the country intends to expel up to 80,000 failed asylum-seekerswho arrived last year.

Theauthorities say there's been a big increase in the number of threats and violent incidents atreception centres.

The government's been under pressure from charities and opposition parties to accept 3,000refugee children as part of its response to the migrant crisis. Now, the Immigration Minister,James Brokenshire, has asked the U.N. High Commissioner for Refugees to identifyunaccompanied children and help to bring them to the U.K. But they'll come from the countriesneighbouring Syria, not from among the one million refugees who've arrived in Europe. And thegovernment has not put a figure on how many it will take.

This is thetenth time in a row that Facebook has exceeded investors' expectations for both growth andprofit. And that success is down to the site being able to offer advertising that works on peopleusing Facebook on their mobile phones. Shares rose by nearly 10% after adding on theexpectations that things will only get better from here. The company is making big strikes innew areas like video and virtual reality.

A computer programme has beaten a professional player at the popular Chinese game Go, forthe first time. The programme, AlphaGo, won five games in a row against the Europeanchampion. Players used black and white pieces, vowing to take control of territory on awooden checker board. Demis Hassabis is one of the founders of DeepMind, the LondonArtificial Intelligence Company which developed the programme.
Before the match, we suspected we might be stronger than him. But we obviously didn't know,because we didn’t entirely test it against their own test systems, and of course, it was a historicmoment. So it was a fantastically exciting game, actually. It was a very close game. And I guessit was a mixture of relief and amazement and excitement when we did actually win.
That's the BBC News.
