Mount Vesuvius eruption turned part of man’s brain into glass after super-hot ash cloud
A man’s brain was partly turned into glass after Mount Vesuvius erupted.
Researchers discovered dark fragments resembling obsidian in the skull of a man in the ancient settlement of Herculaneum.
Along with Pompeii, the ancient settlement was obliterated in 79AD when the volcano erupted, killing thousands and burying both under a thick layer of volcanic material and mud – preserving them in excellent condition for future archaeologists.

The man was first discovered in the 1960s inside a building called the College of the Augustales, which was dedicated to the cult of Emperor Augustus.
He is thought to have been the college’s custodian and was killed in his bed, around midnight when he was assumed to be asleep, in the first effects of the eruption as the burning hot ash cloud hit.
The city was buried in the latter stages of the geological event.
But after his remains were re-examined more recently, the glass fragments were discovered.
In a paper published on Thursday, researchers said this was the “only such occurrence” of this happening on Earth.
It was caused by a super-hot ash cloud that is thought to have suddenly descended on his city, likely instantly killing the inhabitants.
The glass was formed by vitrification, the process of transforming a substance into glass, when the brain’s organic material was exposed to the incredibly high temperatures – at least 510C (950F) – before rapidly cooling.
“The glass formed as a result of this process allowed for an integral preservation of the biological brain material and its microstructures,” said forensic anthropologist Pier Paolo Petrone of Universita di Napoli Federico II, one of the study’s lead researchers.

He added: “The only other type of organic glass we have evidence of is that produced in some rare cases of vitrification of wood, sporadic cases of which have been found at Herculaneum and Pompeii.
“However, in no other case in the world have vitrified organic human or animal remains ever been found.”

Mr Petrone continued: “I was in the room where the college’s custodian was lying in his bed to document his charred bones.
“Under the lamp, I suddenly saw small glassy remains glittering in the volcanic ash that filled the skull.
“Taking one of these fragments, it had a black appearance and shiny surfaces quite similar to obsidian, a natural glass of volcanic origin – black and shiny, whose formation is due to the very rapid cooling of the lava.
“But, unlike obsidian, the glassy remains were extremely brittle and easy to crumble.”

Trump criticises Putin after potentially ‘historic’ meeting with Zelenskyy before Pope’s funeral
Donald Trump has criticised Vladimir Putin and suggested a shift in his stance towards the Russian president after a meeting with Volodymyr Zelenskyy before the Pope’s funeral.
The Ukrainian president said the one-on-one talks could prove to be “historic” after pictures showed him sitting opposite Mr Trump, around two feet apart, in the large marble hall inside St Peter’s Basilica.
The US president said he doubted his Russian counterpart’s willingness to end the war after leaving Rome after the funeral of Pope Francis at the Vatican.

In a post on his Truth Social platform, he said “there was no reason” for the Russian president “to be shooting missiles into civilian areas, cities and towns, over the last few days”.

He added: “It makes me think that maybe he doesn’t want to stop the war, he’s just tapping me along, and has to be dealt with differently, through ‘Banking’ or ‘Secondary Sanctions?’ Too many people are dying!!!”
The meeting between the US and Ukrainian leaders was their first face-to-face encounter since a very public row in the Oval Office in February.
Mr Zelenskyy said he had a good meeting with Mr Trump in which they talked about the defence of the Ukrainian people, a full and unconditional ceasefire, and a durable and lasting peace that would prevent the war restarting.
Other images released by the Ukrainian president’s office show Sir Keir Starmer and French President Emmanuel Macron were present for part of the talks, which were described as “positive” by the French presidency.
Mr Zelenskyy‘s spokesman said the meeting lasted for around 15 minutes and he and Mr Trump had agreed to hold further discussions later on Saturday.

But the US president left Rome for Washington on Air Force One soon after the funeral without any other talks having taken place.
The Ukrainian president’s office said there was no second meeting in Rome because of the tight schedule of both leaders, although he had separate discussions with Mr Starmer and Mr Macron.
The French president said in a post on X “Ukraine is ready for an unconditional ceasefire” and that a so-called coalition of the willing, led by the UK and France, would continue working to achieve a lasting peace.
There was applause from some of the other world leaders in attendance at the Vatican when Mr Zelenskyy walked out of St Peter’s Basilica after stopping in front of the pontiff’s coffin to pay his respects.

Sir Tony Brenton, the former British ambassador to Russia, said the event presents diplomatic opportunities, including the “biggest possible meeting” between Mr Trump and the Ukrainian leader.
He told Sky News it could mark “an important step” in starting the peace process between Russia and Ukraine.
Professor Father Francesco Giordano told Sky News the meeting is being called “Pope Francis’s miracle” by members of the clergy, adding: “There’s so many things that happened today – it was just overwhelming.”
The bilateral meeting comes after Mr Trump’s peace negotiator Steve Witkoff held talks with Mr Putin at the Kremlin.
They discussed “the possibility of resuming direct negotiations between Russia and Ukraine”, Kremlin aide Yuri Ushakov said.

Russia and Ukraine have not held direct talks since the early weeks of the war, which began in February 2022.
Mr Trump has claimed a deal to end the war is “very close” and has urged Mr Zelenskyy to “get it done” in a post on his Truth Social platform.
He has previously warned both sides his administration would walk away from its efforts to achieve a peace if the two sides do not agree a deal soon.
Meanwhile, the Polish armed forces said a Russian military helicopter violated its airspace over the Baltic Sea on Friday evening.
“The nature of the incident indicates that Russia is testing the readiness of our air defence systems,” they said in a post on X.
On an extraordinary day, remarkable pictures on the margins that capture what may be a turning point for the world.
In a corner of St Peter’s Basilica before the funeral of Pope Francis, the leaders of America and Ukraine sit facing each other in two solitary chairs.
They look like confessor and sinner except we cannot tell which one is which.
Leaning forward hands together in their laps, Donald Trump and Volodymyr Zelenskyy stare at each other in one photo.
In another, the Ukrainian president seems to be remonstrating with the US president. This is their first encounter since their infamous bust-up in the Oval Office.

Other pictures show the moment their French and British counterparts introduced the two men. There is a palpable sense of nervousness in the way the leaders engage.
We do not know what the two presidents said in their brief meeting.
But in the mind of the Ukrainian leader will be the knowledge President Trump has this week said America will reward Russia for its unprovoked brutal invasion of his country, under any peace deal.
Mr Trump has presented Ukraine and Russia with a proposal and ultimatum so one-sided it could have been written in the Kremlin.
Kyiv must surrender the land Russia has taken by force, Crimea forever, the rest at least for now. And it must submit to an act of extortion, a proposed deal that would hand over half its mineral wealth effectively to America.
The world leaders shared a moment before the service
Afterwards, Zelenskyy said it had been a good meeting that could turn out to be historic “if we reach results together”.
They had talked, he said, about the defence of Ukraine, a full and unconditional ceasefire and a durable and lasting peace that will prevent a war restarting.
The Trump peace proposal includes only unspecified security guarantees for Ukraine from countries that do not include the US. It rules out any membership of Ukraine.
Ukraine’s allies are watching closely to see if Mr Trump will apply any pressure on Vladimir Putin, let alone punish him for recent bloody attacks on Ukraine.
Or will he simply walk away if the proposal fails, blaming Ukrainian intransigence, however outrageously, before moving onto a rapprochement with Moscow.
If he does, America’s role as guarantor of international security will be seen effectively as over.
This could be the week we see the world order as we have known it since the end of the Second World War buried, as well as a pope.
