This Is Why

In what might feel like a rare break from sunshine, the UK is preparing itself for the most spectacular solar eclipse in a generation.
The cosmic phenomenon occurs when the moon passes directly between Earth and the sun, meaning the country will be slowly plunged into darkness.
So, how can you watch safely? What is it about an eclipse that fascinates us? And with the Perseid meteor shower also taking place, what other celestial wonders might you witness if you make a habit of gazing up at the night sky?
Niall Paterson is joined by Dr Jenifer Millard, co-presenter of the Awesome Astronomy podcast.

Some leaders have gone to extreme measures to save their jobs - but is allowing a deadly war to rage on indefinitely a step too far?
That is what many believe Israel's prime minister Benjamin Netanyahu is doing after he rejected Donald Trump's 15-point peace plan for Gaza.
The proposal was designed to end more than two years of war between Israel and Hamas - so why has Netanyahu rejected it? And can there ever be peace in Gaza with him in power?
Niall Paterson is joined by Middle East expert Dr H. A. Hellyer, a senior associate fellow at the Royal United Services Institute.

Artificial intelligence is already changing how we work, communicate and find information. But could its biggest impact be on science?
Demis Hassabis is one of the most influential figures in AI. An artificial intelligence researcher and entrepreneur, he is the co-founder of Google DeepMind, having recently stepped down as chief executive to become the company's chair and chief scientist at its parent company Alphabet.
His is also co-founder and CEO of Isomorphic Labs, and an AI adviser to the UK government.
DeepMind has used AI to predict the structure of proteins, a breakthrough that helped Hassabis win a Nobel Prize and could accelerate the development of new medicines. And the ambition goes much further: using AI to tackle some of the biggest unanswered questions in biology, physics and beyond.
Niall Paterson speaks to Sebastian Mallaby, journalist and author of The Infinity Machine, about the extraordinary ambition behind DeepMind, why its approach to AI is different from some of its Silicon Valley rivals, and whether the technology could ultimately become the world's smartest scientist.

UEFA has said it is not lifting its boycott of the World Cup after FIFA president Gianni Infantino held a crisis meeting in Morocco. This appears to be in defiance of the letter issued by FIFA at the end of the meeting, which said it would "no longer tolerate any attacks on its integrity".
The letter said Infantino had continued to have the support of everyone who attended the meeting, but some of FIFA's management team who had been critical of him were not there.
For now, he seems determined to hang on to power, but with UEFA also not backing down, is his position still under threat?

Britain is on track for one of its worst harvests on record, according to new analysis by the Energy and Climate Intelligence Unit (ECIU) think tank.
It's bad news for farmers whose businesses are struggling, bad news for consumers who could see higher prices and potentially bad news for the country.
We are far from being self-sufficient in our food production, already importing 40% of what we eat. So what should the government be doing to help farmers deal with the effects of climate change and protect our food security?
Mhari Aurora is joined by Sky News climate reporter Victoria Seabrook, and Martin Lines, a farmer in south Cambridgeshire who leads the Nature Friendly Farming Network.
