Unsafe concrete crisis could extend to other public buildings, experts warn
The crisis over unsafe concrete in schools may extend beyond the education sector to other types of public buildings, experts have warned.
They say the scale of the problem with reinforced autoclaved aerated concrete (RAAC) is “much bigger than schools” and could include hospitals, police stations, and court buildings.
Even private sector sites such as shopping centres and residential tower blocks could also be impacted, experts say.
Meanwhile, Labour MP Dame Meg Hillier, chairwoman of parliament’s Public Accounts Committee, has warned the issues with RAAC in schools are just the “tip of the iceberg” of maintenance issues for sites across England.
It comes after 104 schools and colleges were told by the Department for Education (DfE) to partially or fully shut buildings just days before the start of the new school year over fears about the safety of facilities built with RAAC.
Labour has called for an “urgent audit” across the public sector estate, while the Liberal Democrats say the public must be given “urgent clarity” over whether hospital wards and buildings could also be forced to close.

Concrete crisis explained
RAAC is essentially a lighter-weight form of concrete, used to build roofs, schools, colleges and other buildings from the 1950s until the mid-1990s,
But experts fear that the material has now reached the end of its shelf life and is liable to collapse.
Though not confirmed, it is estimated that around 24 schools in England have been told to close entirely because of the presence of RAAC.
Schools minister Nick Gibb has admitted more could be asked to shut classrooms.
But the problem could be far wider than just schools, experts say, with other buildings at risk of “sudden and catastrophic collapse” if RAAC is not removed.
Chris Goodier, professor of construction engineering and materials at Loughborough University, said the “scale of the problem is much bigger than schools”.
He says it could cover public sectors including health, defence, and justice, as well as some private sector buildings.
NHS providers have already identified 14 hospitals, which were constructed “either wholly or in major part with RAAC”. Seven of these are considered “critical” and not fit for purpose beyond 2030.
Three buildings operated by Police Scotland have also been found to contain RAAC after an investigation of 65 structures.
Matt Byatt, president of the Institution of Structural Engineers, says any high-rise buildings with flat roofs constructed between the late 1960s and early 1990s may also contain RAAC.

‘New evidence’ to shut unsafe schools
According to Dame Meg, the DfE has been aware of a “significant problem” with RAAC since a roof collapse in 2018.
She warns that this week’s announcement could have a “significant impact” on the department’s wider school maintenance programmes.

Ministers urged to publish full list of impacted schools
In an opinion piece in The Times newspaper, she writes: “At our hearing in July it was clear that officials were being thorough with the proportion of school buildings they were working on, including the surveys of 600 schools with RAAC which have led to this week’s decision.
“But this is the tip of the iceberg of a failing school estate in England. Most of the 700,000 pupils currently being educated in substandard buildings are not in RAAC buildings and will now be waiting longer for the improvements they need.”

Around 104 schools or “settings” in England found with concrete prone to collapse are set to be closed or disrupted – on top of 52 that have already been affected this year.
The government says the schools needed to close because of safety fears, which have arisen due to concrete failing “with no warning”.
While the DfE has previously focused on remediation, Mr Gibb says the department is now taking the “cautious approach” that all of the concrete should be removed.
Labour is calling on ministers to “come clean” and publish the full list of schools that will be impacted, as they have not yet been publicly named.
It has also accused the government of “neglect and incompetence” over their handling of the issue.

Satoshi Nakamoto, the pseudonymous creator of Bitcoin, marks their 50th birthday amid a year of rising institutional and geopolitical adoption of the world’s first cryptocurrency.
The identity of Nakamoto remains one of the biggest mysteries in crypto, with speculation ranging from cryptographers like Adam Back and Nick Szabo to broader theories involving government intelligence agencies.
While Nakamoto’s identity remains anonymous, the Bitcoin (BTC) creator is believed to have turned 50 on April 5 based on details shared in the past.
According to archived data from his P2P Foundation profile, Nakamoto once claimed to be a 37-year-old man living in Japan and listed his birthdate as April 5, 1975.

Nakamoto’s anonymity has played a vital role in maintaining the decentralized nature of the Bitcoin network, which has no central authority or leadership.
The Bitcoin wallet associated with Nakamoto, which holds over 1 million BTC, has laid dormant for more than 16 years despite BTC rising from $0 to an all-time high above $109,000 in January.

Nakamoto’s 50th birthday comes nearly a month after US President Donald Trump signed an executive order creating a Strategic Bitcoin Reserve and a Digital Asset Stockpile, marking the first major step toward integrating Bitcoin into the US financial system.

Nakamoto’s legacy: a “cornerstone of economic sovereignty”
“At 50, Nakamoto’s legacy is no longer just code; it’s a cornerstone of economic sovereignty,” according to Anndy Lian, author and intergovernmental blockchain expert.
“Bitcoin’s reserve status signals trust in its scarcity and resilience,” Lian told Cointelegraph, adding:
“What’s fascinating is the timing. Fifty feels symbolic — half a century of life, mirrored by Bitcoin’s journey from a white paper to a trillion-dollar asset. Nakamoto’s vision of trustless, peer-to-peer money has outgrown its cypherpunk roots, entering the halls of power.”
However, lingering questions about Nakamoto remain unanswered, including whether they still hold the keys to their wallet, which is “a fortune now tied to US policy,” Lian said.

Is Satoshi Nakamoto wealthier than Bill Gates?
In February, Arkham Intelligence published findings that attribute 1.096 million BTC — then valued at more than $108 billion — to Nakamoto. That would place him above Microsoft co-founder Bill Gates on the global wealth rankings, according to data shared by Coinbase director Conor Grogan.

If accurate, this would make Nakamoto the world’s 16th richest person.
Despite the growing interest in Nakamoto’s identity and holdings, his early decision to remain anonymous and inactive has helped preserve Bitcoin’s decentralized ethos — a principle that continues to define the cryptocurrency to this day.

The United States stock market lost more in value over the April 4 trading day than the entire cryptocurrency market is worth, as fears over US President Donald Trump’s tariffs continue to ramp up.
On April 4, the US stock market lost $3.25 trillion — around $570 billion more than the entire crypto market’s $2.68 trillion valuation at the time of publication.
Nasdaq 100 is now “in a bear market”
Among the Magnificent-7 stocks, Tesla (TSLA) led the losses on the day with a 10.42% drop, followed by Nvidia (NVDA) down 7.36% and Apple (AAPL) falling 7.29%, according to TradingView data.
The significant decline across the board signals that the Nasdaq 100 is now “in a bear market” after falling 6% across the trading day, trading resource account The Kobeissi Letter said in an April 4 X post. This is the largest daily decline since March 16, 2020.
“US stocks have now erased a massive -$11 TRILLION since February 19 with recession odds ABOVE 60%,” it added. The Kobessi Letter said Trump’s April 2 tariff announcement was “historic” and if the tariffs continue, a recession will be “impossible to avoid.”

On April 2, Trump signed an executive order establishing reciprocal tariffs on trading partners and a 10% baseline tariff on all imports from all countries.
Trump said the reciprocal tariffs will be roughly half the rate US trading partners impose on American goods.

Meanwhile, the crypto industry has pointed out that while the stock market continues to decline, Bitcoin (BTC) remains stronger than most expected.

Even some crypto skeptics have pointed out the contrast between Bitcoin’s performance and the US stock market during the recent period of macro uncertainty.
Stock market commentator Dividend Hero told his 203,200 X followers that he has “hated on Bitcoin in the past, but seeing it not tank while the stock market does is very interesting to me.”
Meanwhile, technical trader Urkel said Bitcoin “doesn’t appear to care one bit about tariff wars and markets tanking.” Bitcoin is trading at $83,749 at the time of publication, down 0.16% over the past seven days, according to CoinMarketCap data.
