Donald Trump wrote in a post on Truth Social that he had discussed with Russian President Vladimir Putin Iran and "the fact that time is running out on Iran's decision pertaining to nuclear weapons, which must be made quickly"."We will need a definitive answer in a very short period of time!"

Trump has warned Iran's leaders that it could face US and Israeli military action if the negotiations are not successful, and he is said to have given them a two-month deadline in a letter he sent in early March.He has also insisted Iran would have to halt all uranium enrichment under any deal.As supreme leader, Ayatollah Khamenei has final say on Iran's most important issues, including a potential nuclear agreement.

"Uranium enrichment is the key to our nuclear programme and the enemies have focused on the enrichment," he declared in his speech on Wednesday."The rude and arrogant leaders of America repeatedly demand that we should not have a nuclear programme. Who are you to decide whether Iran should have enrichment?"

Iran's chief negotiator, Foreign Minister Abbas Araghchi, wrote on X: "Iran has paid dearly for these capabilities, and there is no scenario in which we will give up on the patriots who made our dream come true."

"To reiterate: No enrichment, no deal. No nuclear weapons, we have a deal."Cassettes of magnetic tape known as LTO (Linear Tape Open), are the most common form, but newer innovations promise to revolutionise how we preserve information.

For example, Microsoft's Project Silica has developed 2mm-thick panes of glass, onto which chunks of data is transferred by powerful lasers.Meanwhile a team of scientists from the University of Southhampton have created a so-called 5D memory crystal, which has saved a record of the human genome.

That's also been placed in the, another vault safeguarding historic documents, hidden in a salt mine in Austria.
