Hard Numbers: A billion-dollar typo

52: Only a slim majority (52 percent) of Iranians polled now support the 2015 nuclear agreement, which the US walked out of last year. Back in 2015 more than three quarters of those surveyed approved of the agreement. Hardliners in Tehran are pleased to see this: they never much liked the deal to begin with.

2: North Korea yesterday test-launched two more short-range missiles. The move follows a similar move last Saturday. None of this violates Kim Jong-un's promise to stop testing long-range or nuclear missiles, but angrily firing missiles into the sea is seen as a sign that North Korea is frustrated by scant progress in negotiations with the US over its nuclear program.

1.6: Australia's government has printed $1.6 billion worth of currency… with a typo on it. The new Aussie 50-dollar bill, the country's most widely circulated bill, misspells the word "responsibility" in quoting a speech by the country's first female parliamentarian, Edith Cowan. We have to ask: whose responsibility is this?

0: So far, zero European countries have heeded the Trump Administration's call to ban the Chinese tech firm Huawei from their plans to build 5G communications networks, prompting US Secretary of State Pompeo to accuse them of going "wobbly."

Scientists, engineers and technologists are turning to nature in search of solutions to climate change. Biomimicry is now being applied in the energy sector, medicine, architecture, communications, transport and agriculture in a bid to make human life on this planet more sustainable and limit the impacts of global warming. New inventions have been inspired by humpback whales, kingfishers and mosquitoes.

The drumbeat for regulating artificial intelligence (AI) is growing louder. Earlier this week, Sundar Pichai, the CEO of Google's parent company, Alphabet, became the latest high-profile Silicon Valley figure to call for governments to put guardrails around technologies that use huge amounts of (sometimes personal) data to teach computers how to identify faces, make decisions about mortgage applications, and myriad other tasks that previously relied on human brainpower.

January 27 marks 75 years since the liberation of Auschwitz-Birkenau, the largest Nazi extermination camp. But even as some 40 heads of state gathered in Jerusalem this week to commemorate the six million Jews who were killed, a recent Pew survey revealed that many American adults don't know basic facts about the ethnic cleansing of Europe's Jews during the Second World War. Fewer than half of those polled knew how many Jews were killed in the Holocaust, and close to a third didn't know when it actually happened. Here's a look at some of the numbers.

1: The Greek parliament has elected a woman president for the first time since the country's independence some 200 years ago. A political outsider, Katerina Sakellaropoulou is a high court judge with no known party affiliation. "Our country enters the third decade of the 21st century with more optimism," Greece's prime minister said.

A quarantine in China– Local authorities have locked down the city of Wuhan, the source of the outbreak of a new and potentially deadly respiratory virus that, as of Thursday morning, had infected more than 540 people in at least six countries. Other nearby cities were also hit by travel restrictions. Rail and air traffic out of Wuhan has been halted. Public transportation is shut, and local officials are urging everyone to stay put unless they have a special need to travel. Wuhan is a city of 11 million people, many of whom were about to travel for the Chinese New Year. We're watching to see whether these extraordinary measures help stem the outbreak, but also to see how the people affected respond to the clampdown.
