Rising tensions between the US and Iran threaten the security of the Strait of Hormuz, a narrow waterway plied daily by dozens of tankers carrying oil out to the rest of the world from Qatar, Saudi Arabia, Iran, Iraq, Kuwait, and the United Arab Emirates. At the moment, the US Navy provides security in the international waters there, but President Trump has suggested other major oil consuming countries should pitch in more to help. Here's a look at the countries that are most dependent on oil exports shipped through the world's most important energy chokepoint.
Electricity consumption in our homes contributes 25% of all greenhouse gas emissions. What if we could transform this huge contributing factor into a solution? That's what Eni's luminescent solar concentrators can do. These transparent, colored slabs can be inserted into home windows to capture solar energy and generate electricity. By adjusting to the brightness and temperature of your home, they can even save you money on heating and air conditioning costs.
Is the lithium-ion battery the most important invention of the past 50 years?
It is definitely important. And the inventors just won a Nobel Prize. Powers all kinds of stuff. But no, I'm gonna go with the Internet as the most important invention of the last 50 years.
Was PG&E shutting off power to 600,000 Californian customers the right call?
Hard to say. They do have a pretty solid argument that you have to shut off powers at this time of the year, with these kinds of winds coming, to prevent forest fires. On the other hand, surely there's a better way to get the same benefit in forest fire reduction than taking away all the electricity? It's a big problem.
What can we expect with the just announced PlayStation 5?
It's coming next holiday season. It's going to start much faster. The hard drives a lot better. The thing I'm most excited about, the haptics in the controller. When you play video games, there's usually some soft rumbling that can help you understand feedback. There's gonna be a lot of much cooler stuff in the PS5.

David Miliband: The answer to that depends on whether or not you believe the opinion polls, because the opinion polls are clear that Boris Johnson the Conservative Party are ahead of a divided opposition between Labour and the Liberal Democrats. The lead ranges from 5 to 15 points. What does seem to be overwhelmingly clear, what is overwhelmingly clear, is that the leader of the opposition is immensely unpopular, with an unpopularity rating of about minus 50 percent. And that leads many conservatives to believe that it will be propitious for the conservatives to call or affect a general election and it leads many Labour MPs and supporters to be extremely fearful of the outcome.
The BRICS – a bloc of nations comprising Brazil, Russia, India, China and South Africa – meets next month in Brazil's capital for its annual summit. The idea of the "BRIC" grouping comes from a 2001 Goldman Sachs paper, which predicted that these rising economies, despite their major differences, would soon be among the world's largest, and that as a group they would command more global clout as a result. The idea took on a real-world structure in 2009, when Brazil, Russia, India and China began holding regular BRIC summits, and in 2010 they invited South Africa to join as well. But this vision of BRICS power hasn't necessarily materialized: China's share of global GDP has boomed – and India's growth has been significant, too. But the B, R, and S shares of the global economy have actually shrunk over the past 20 years. Here's a look at how these economies have fared since the idea of the BRICS was born.
Turkey's ongoing military incursion into Syria began when President Donald Trump ordered the withdrawal of US forces from land in northern Syria held by the Kurdish-led Syrian Democratic Forces (SDF).
The US has long considered the SDF an important ally in the drive to destroy ISIS. Turkey, by contrast, accuses the SDF of support for Kurdish separatists inside Turkey.
