On Sunday, the leaders of Ethiopia and Eritrea built a bridge of love across a long-disputed border. That’s not us getting mushy in the mid-summer heat – that’s a direct quote from Ethiopian Prime Minister Abiy Ahmed, who has agreed with his Eritrean counterpart Isaias Afwerki to finally settle a late-1990s conflict that killed 80,000 people, displaced half a million more, and fueled destabilizing proxy fights between the countries elsewhere in East Africa ever since.

The peace is largely the initiative of the youthful Mr. Abiy – a former intelligence officer who, since taking power earlier this spring, has made waves by relaxing political controls, pledging economic reforms, and promising a more inclusive government. Peace with Eritrea would free up economic resources and open up greater avenues for development, not least by enabling landlocked Ethiopia to regain access to the Red Sea via Eritrean ports.

For Eritrea, peace offers a chance to emerge from the ruthless militarization and economic isolation that have made it one of the world’s most repressive regimes, driving hundreds of thousands of its people northward to Europe in search of better opportunities in recent years.

To be sure, plenty of challenges remain – for one thing, Ethiopian troops still need to leave border areas that they have occupied in contravention of UN findings, and thorny questions of territorial and population exchanges also remain. It’s also unclear whether Eritrea’s Afwerki can ease tensions without losing control over a system that has been shaped by more than two decades of war-footing.

But in a world where borders and walls are the thing these days, a bridge of love isn’t a bridge too far, is it?

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.

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.
