Most of us can remember exactly where we were when we heard about the September 11 terror attacks. This type of vivid recollection has been documented for other major world events too. They’re known as flashbulb memories and feel remarkably accurate, yet research suggests they can be just as unreliable as any other memory.

So why do we trust these memories so strongly and could misremembering actually benefit us?

US President, Donald Trump, has said he will offer every adult American $5,000 (£3,700) if the Republican party wins the midterms.

President Trump gave no detail on how it would work or how he would fund it. Speaking at the party’s first-ever convention in the middle of a US presidential term. He also said that the country’s war with Iran would not end until after the midterms. James is joined by Caitriona Perry and Faisal Islam to unpack these latest statements.

The far-right Alternative for Germany (AfD) has won a decisive victory in Germany’s eastern state of Saxony-Anhalt, far ahead of mainstream rivals.

But preliminary results show it has fallen short of an outright majority needed to govern alone, with 43.8% of the vote to the conservative CDU’s 17.2%, and tricky negotiations on who will run the state lie ahead.

AfD’s charismatic leader in the state, Ulrich Siegmund, said it was “sensational” and the party had won a mandate to govern.

No far-right party has controlled a German state since World War Two, and governing at state level would mean powers over policing, local education and culture.
