Making Coffee More Sustainable

Coffee is one of the most popular drinks in the world, but that means it creates a lot of waste in the form of cups and used coffee grinds. Every year, we drink out of 600 billion single-use plastic and paper cups, most of which end up in a landfill or our environment. Could coffee also contribute to a more sustainable future? A German company is now recovering leftover coffee grounds from bars, restaurants and hotels, and it's recycling them into reusable coffee cups. In other words, they're creating cups of coffee made from coffee.

A few days ago, the New York Times published a bombshell report on the Chinese government's systematic oppression of Muslims in Western China. The story was about many things: human rights, geopolitics, Chinese society – but it was also about technology: Beijing's repression in Xinjiang province is powered in part by facial recognition, big data, and other advanced technologies.

It's a concrete example of a broader trend in global politics: technology is a double-edged sword with sharp political consequences. Artificial intelligence, for example, can help develop new medicines but it can also support surveillance states. Social media helps nourish democracy movements and entertains us with cat memes, but it also feeds ISIS and 4Chan.

Increasingly violent anti-government protests in Hong Kong have dealt a major blow to the city's once booming economy. Tourism – an economic lifeline in that city – has dropped, and retailers are suffering from a sharp decline in sales. Now, six months since the unrest began, Hong Kong has recorded its first recession in a decade, meaning its economy has contracted for two consecutive quarters. Here's a look at how Hong Kong's quarterly gross domestic product (GDP) growth has fared during the past two years.

Tehran's Next Move: "We don't want an Islamic Republic, we don't want it," was the chant heard among some protesters in Tehran over the weekend after the government announced a 50 percent fuel price hike meant to fund broader support for the country's poor. Under crippling US sanctions, the country's economy has plummeted, unleashing a "tsunami" of unemployment. What started Friday as nationwide economic protests took on a political coloring, as protestors in some cities tore up the flag and chanted "down with [Supreme Leader] Khamenei!". The unrest seems to be related, at least indirectly, to widespread demonstrations against Tehran-backed regimes in Iraq and Lebanon as well. Economically-motivated protests erupt in Iran every few years, but they tend to subside within weeks under harsh government crackdowns. So far, the authorities have shut down the internet to prevent protestors from using social media to organize rallies. But Iran's powerful Revolutionary Guards Corps has warned of more "decisive action" if the unrest continues.

13 billion: Building a single state-of-the-art US aircraft carrier costs about $13 billion, a figure that exceeds total military spending by countries like Poland, the Netherlands, or Pakistan. But as China's ability to hit seaborne targets improves, the Economist asks if carriers are "too big to fail." (Come for that, stay for the many strange Top Gun references in the piece.)
