Record concentration of microplastics found in Arctic

Image copyright Alfred Wegener Institute/ R.Stein Image caption Plastic particles end up in sea ice floating in the Arctic Record levels of microplastics have been found trapped inside sea ice floating in the Arctic. Ice cores gathered across the Arctic Ocean reveal microplastics at concentrations two to three times higher than previously recorded. As sea ice melts with climate change, the plastic will be released back into the water, with unknown effects on wildlife, say German scientists. Traces of 17 different types of plastic were found in frozen seawater. Their…

Why It Seems Like Everyone Is Always Angry With You

“If you think they look angry then you may respond angrily,” said Abigail Marsh, the director of the Laboratory on Social and Affective Neuroscience at Georgetown University. What interested Dr. Schermerhorn was whether an even more common issue — conflict between parents — might also take a toll. She tested this by gathering 99 children, ages nine to 11, who lived in households with their two married biological parents. After the children completed a questionnaire with statements such as, “My parents get really mad when they argue,” she tested their…

YouTube Says Computers Are Catching Problem Videos

Figuring out how to remove unwanted videos — and balancing that with free speech — is a major challenge for the future of YouTube, said Eileen Donahoe, executive director at Stanford University’s Global Digital Policy Incubator. “It’s basically free expression on one side and the quality of discourse that’s beneficial to society on the other side,” Ms. Donahoe said. “It’s a hard problem to solve.” YouTube declined to disclose whether the number of videos it had removed had increased from the previous quarter or what percentage of its total uploads…

Under Obama administration guidelines, organizations awarded most of the grants had to use curriculums that were on an evidence-supported list. Under the new guidelines, they simply have to comply with more general requirements like “support personal attitudes and beliefs that value…

How Looming Privacy Regulations May Strengthen Facebook and Google

That Facebook and Google may emerge stronger from all of this can seem like a distant prospect. The Silicon Valley companies have been under scrutiny for months for how they collect and use people’s data, with Facebook reeling from revelations that the political research firm Cambridge Analytica harvested the personal information of up to 87 million of its users. That led to Congress dragging Mark Zuckerberg, Facebook’s chief executive, to Washington this month for a grilling. Photo The London offices of the political research firm Cambridge Analytica.

Apple’s Deal for Shazam Delayed in Europe Over Data Concerns

European authorities are raising alarms because Shazam has important data about Apple’s rivals, potentially allowing the company to “directly target its competitors’ customers and encourage them to switch” to Apple’s own streaming service, the European Commission, the European Union’s executive arm, said in a statement. “Competing music streaming services could be put at a competitive disadvantage,” the commission said. It added that it wanted to prevent Apple from blocking Shazam from referring users to other music services. The European Commission has until Sept. 4 to make a final decision on…
