Artists are challenging Facebook’s policy of refusing to take down videos which have been manipulated to misrepresent their subjects by creating one about Mark Zuckerberg.

The stunt follows criticism of Facebook for refusing to remove a video of US Democratic politician Nancy Pelosi, a prominent critic of President Donald Trump, which had been slowed down to make her appear inebriated.

Artists Bill Posters and Daniel Howe, working with an advertising company, created the video featuring Facebook’s founder and chief executive giving a speech about his desire to control the world’s data.

The so-called “deepfake” speech features the Facebook founder appearing to revel in knowing social media users’ “secrets” before thanking the artists behind the clip.

“Imagine this for a second: One man, with total control of billions of people’s stolen data,” Mr Zuckerberg appears to say.

“All their secrets, their lives, their futures. I owe it all to Spectre. Spectre showed me that whoever controls the data, controls the future.”

As in many manipulated videos which use artificial intelligence software to manipulate the frames of an existing video to change someone’s appearance, there are strange movements around Mr Zuckerberg’s mouth which give the game away.

Journalists who check the origin of such footage can see that it is a doctored version of a speech which Mr Zuckerberg gave in September 2017, fittingly about manipulation on Facebook during the US presidential election.

The video was created, alongside others featuring Kim Kardashian and Donald Trump, by advertising company CannyAI’s video dialogue replacement (VDR) technology for an exhibition in Sheffield.

Although it is possible to detect the VDR technology in the clip of Mark Zuckerberg, the Kim Kardashian clip is exceptionally convincing.

The sophistication of the technology is expected to improve with time which has prompted concerns that it will be used to spread fake news and disinformation.

At the time Ms Pelosi’s altered video was spreading online – amplified by a tweet from Donald Trump – critics noted that Facebook was alone among social media companies refusing to take it down.

Instead the company merely de-prioritised it so that it did not appear high in users’ news feeds, and was presented alongside information from third-party fact checkers.

Currently no such information appears alongside the Mark Zuckerberg video, but it may be coming if the video gains traction.

A spokesperson for Instagram told Sky News they would not be removing the video.

They said: “We will treat this content the same way we treat all misinformation on Instagram. If third-party fact-checkers mark it as false, we will filter it from Instagram’s recommendation surfaces like Explore and hashtag pages.”

Unhatched birds can warn other eggs in nest of danger by vibrating | Science & Tech News

Published

Unhatched baby seabirds can warn each other of impending danger by vibrating within their shells, scientists have discovered.

A study of yellow-legged gull embryos, found they reacted to warning calls from a parent and even passed on the message to siblings who had not heard the call.

The researchers collected gull eggs and divided them into groups of three.

A week before hatching, two of the three eggs in each nest were temporarily removed and exposed to a recording of a predator alarm call.

The noise was delivered four times a day at random intervals for three minutes at a time until hatching.

The third egg from each group remained in the nest in silence.

All three eggs were then reunited and left to hatch.

It was found the embryos responded to the external alarm calls by vibrating more.

This information appeared to be passed on to the third egg which had not been directly exposed to the sounds and it then mimicked the vibrations.

Experts from the Animal Ecology Group at the University of Vigo in Spain discovered all the chicks underwent genetic changes that delayed hatch time.

There was also evidence of increased production of stress hormones which is known to make birds more aware of their surroundings after hatching.

The findings were published in the journal, Nature Ecology and Evolution.

Bali arrests: Shackled Australians facing jail over ‘cocaine use’ | World News

Published

Two Australian men have been paraded in front of the media a week after being arrested in Bali on suspicion of cocaine use and possession.

Indonesian police are preparing to charge the pair and are currently searching for a third suspect after a series of drug raids in the village of Canggu, a popular nightclub area on the island of Bali.

The two men, who have been named as William Cabantong, 35, and David Van Iersel, 38, were led out in front of the media in hand and foot shackles, alongside local drug suspects.

Police acted on a tip-off, and said they found 1.12g of cocaine in the pockets of one of the men, as well as drug equipment including a set of broken scales.

The men bought 2g of cocaine for three million rupiahs (£172), according to police.

The pair have undergone days of interrogation and tests while in prison. Police say a blood test revealed that both Mr Cabantong and Mr Van Iersel were cocaine users.

Denpasar police chief Ruddi Setiawan told reporters: “We advise tourists, locals, and foreigners to come here for a holiday, don’t come to have a drugs party or to use drugs.

“We will take firm action if any foreigners resist. We will not be lenient.”

The men are expected to be charged under Indonesian law 112, legislation which covers drug possession. The punishment carries a possible jail term of between four and 12 years, as well as a fine of 800 million rupiah (£45,000).

It is understood that both Mr Cabantong and Mr Van Iersel worked as nightclub promoters whilst they lived in Australia before they travelled to Bali.

Indonesia is known for its strong penalties against those who commit drug offences. In 2017, Indonesian President Joko Widodo told police officers to shoot drug traffickers.

He said: “Be firm, especially to foreign drug dealers who enter the country and resist arrest. Shoot them because we indeed are in a narcotics emergency position now.”

Drug-resistant malaria strains spread through south east Asia | World News

Published

on

Strains of drug-resistant malaria are becoming more dominant in Vietnam, Laos and northern Thailand after spreading rapidly from Cambodia.

Malaria is caused by parasites which are carried by mosquitoes and spread through their blood-sucking bites.

And scientists have discovered a growing number of cases where the parasite has mutated making it resistant to drugs.

“We discovered (it) had spread aggressively, replacing local malaria parasites, and had become the dominant strain in Vietnam, Laos and northeastern Thailand,” said Roberto Amato, from the Wellcome Sanger Institute.

Malaria can be successfully treated with medicines if it is caught early enough, but resistance to anti-malarial drugs is growing in many parts of the world, especially in south east Asia.

The first-line treatment for malaria in many parts of Asia in the last decade has been a combination of dihydroartemisinin and piperaquine, also known as DHA-PPQ.

Researchers found in previous work that a strain of malaria had evolved and spread across Cambodia between 2007 and 2013 that was resistant to both drugs.

This latest research, published in The Lancet Infectious Diseases journal, found it has crossed borders and tightened its grip.

“The speed at which these resistant malaria parasites have spread in south east Asia is very worrying,” said Olivo Miotto, who co-led the work.

“Other drugs may be effective at the moment but the situation is extremely fragile and this study highlights that urgent action is needed.”

Almost 220 million people were infected with malaria in 2017, according to World Health Organisation estimates, and the disease killed 400,000 of them.

The vast majority of cases and deaths are among babies and children in sub-Saharan Africa.
