EU to give internet firms 1 hour to remove extremist content

EU to give internet firms 1 hour to remove extremist content

Technology
European authorities are planning to slap internet companies like Google, Twitter and Facebook with big fines if they don't take down extremist content within one hour. European Commission President Jean-Claude Juncker said in a speech Wednesday that the Commission is proposing the new rules as part of efforts to step up the bloc's security. He said that removing material within an hour is important because it's "the critical window in which the greatest damage is done." The EU's executive body said "propaganda that prepares, incites or glorifies acts of terrorism" must be taken offline. Content would be flagged up by national authorities, who would issue removal orders to the internet companies hosting it. Those companies would be given one hour to delete it. The proposal , which still ...

Facebook will not remove fake news – but will 'demote' it

Technology
Facebook says it will not remove fake news from its platform because it does not violate its community standards.The social network is currently running an advertising campaign in the UK that declares "fake news is not our friend".But it said publishers often had "very different points of view" and removing fabricated posts would be "contrary to the basic principles of free speech".Instead, it says posts that it deems to be fake news will be "demoted" in the news feed.Facebook has been scrutinised for its role in spreading fake news after evidence emerged that Russia tried to influence US voters using the social network.On Wednesday, the company held an event in New York where it sought to convince journalists it was tackling the problem.CNN reporter Oliv...
Nanorobots help remove bacteria, toxins from blood

Nanorobots help remove bacteria, toxins from blood

Health
May 31 (UPI) -- Nanorobots that are about 25 times smaller than the width of a human hair have been developed to remove harmful bacteria and toxins by swimming through the bloodstream. Engineers at the University of California San Diego hope one day their proof-of-concept method will offer a safe and efficient way to detoxify and decontaminate biological fluids. Their findings were published Wednesday in the journal Science Robotics. "The idea is to create multifunctional nanorobots that can perform as many different tasks at once," co-first author Berta Esteban-Fernandez de Avila, a postdoctoral scholar at UC San Diego, said in a press release. "Combining platelet and red blood cell membranes into each nanorobot coating is synergistic -- platelets target bacteria, while red blood cells ...

George Michael's family ask fans to remove tributes

Entertainment
George Michael's family has asked fans to remove tributes from the late star's former homes, saying he "would not want to disturb" the neighbours.Fans of the Faith singer have created memorial areas filled with flowers, messages and candles outside his former homes in Highgate, London, and Goring-on-Thames, Oxfordshire.Michael, who sold 120 million records during his career as a solo artist and member of Wham!, died in his Oxfordshire home on Christmas Day 2016.Michael's sisters Mel and Yioda Panayiotou, his father Jack Panos and friend David Austin wrote on the pop icon's official site: "We've been touched by your many tributes celebrating and remembering Yog, reminding us how very much he is missed and loved."The statement reads: "We feel we cannot expect our Highgate and Goring neighbou...
New material can remove salt and metal ions from seawater

New material can remove salt and metal ions from seawater

Science
Feb. 9 (UPI) -- Scientists have developed a new, more efficient way to filter salt and metal ions from water. The method relies on metal-organic frameworks, a unique material with an expansive internal surface area and crystals capable of trapping chemical compounds dissolved in water.Currently, reverse osmosis membranes are responsible for the majority of desalinization efforts. The membranes also serve as the last stage of filtration in most municipal water systems. Unfortunately, the membranes aren't very energy efficient.A team of researchers from Monash University in Australia and the University of Texas in Austin found metal-organic frameworks, or MOFs, can be designed to selectively filter both salt and ions.The differently sized nanoscale substructures inside the unique materials s...
