After we published this story, Google reached out to say that it doesn’t currently use Gmail keywords to target web ads. We’ve updated the story to reflect that.
When Google bought the advertising network DoubleClick in 2007, Google founder Sergey Brin said that privacy would be the company’s “number one priority when we contemplate new kinds of advertising products.”
And, for nearly a decade, Google did in fact keep DoubleClick’s massive database of web-browsing records separate by default from the names and other personally identifiable information Google has collected from Gmail and its other login accounts.
The change is enabled by default for new Google accounts. Existing users were prompted to opt-in to the change this summer.
The United Nations (UN) has celebrated Wonder Woman’s 75th birthday by naming the comic book character as its new honorary ambassador for the empowerment of women and girls, despite frustration from both inside and outside the world organisation that the spot should go to a real and less-sexualised woman.
The ceremony, at the Economic and Social Council chamber, was marred by some 50 UN staffers who silently turned their back to the stage, some with their fists in the air.
The super heroine’s image will be used by the UN on social media platforms to promote women’s empowerment, including on gender-based violence and the fuller participation of women in public life, using the hashtag #WithWonderWoman.
If scientists can figure out how to convert atmospheric carbon dioxide into fuel – and do it at an industrial scale – it would, quite literally, change the world. Last month, we hit the highest levels of atmospheric CO2 in 4 million years, and it’s now permanent, meaning we’ll never be able to drop to ‘safe’ levels again.
But if we can turn CO2 into a fuel source, we can at least slow things down a bit, and now researchers have developed a process that can achieve this with a single catalyst.
“We discovered somewhat by accident that this material worked,” said one of the team, Adam Rondinone, from the US Department of Energy’s Oak Ridge National Laboratory.
“We were trying to study the first step of a proposed reaction when we realised that the catalyst was doing the entire reaction on its own.”
Rondinone and his colleagues had put together a catalyst using carbon, copper, and nitrogen, by embedding copper nanoparticles into nitrogen-laced carbon spikes measuring just 50-80 nanometres tall. (1 nanometre = one-millionth of a millimetre.)
