Scientists have long debated the greatest possible age of a person, with previous studies placing the limit at up to 150 years. But in the past 25 years, no one has surpassed the record for the world’s oldest person, held by Jean Louise Calment, who died at age 122 in 1997.

“This has led people to argue that the maximum life span has been reached,” David McCarthy (opens in new tab) , an assistant professor of risk management and insurance at the University of Georgia, told Live Science. In a new study, McCarthy and his colleagues say they’ve uncovered evidence that this longevity record will be broken within the next four decades. The team did not propose a maximum age that humans can live to, but rather, they used a mathematical model to project what mortality trends might look like in upcoming years. 

However, not everyone agrees with the team’s conclusions, experts told Live Science.

In the study, published March 29 in the journal PLOS One (opens in new tab) , the scientists analyzed mortality data from hundreds of millions of people in 19 countries who were born between the 1700s and the late 1900s, up to 1969. They tweaked an existing mathematical model to explore how the mortality rates among people ages 50 to 100 differed in people with different birth years. They then used this information to predict the ages that people may reach in the future.

In this model, mortality rates are assumed to increase exponentially beyond age 50 and then plateau at extremely old ages, McCarthy said. Such modeling can offer clues as to whether humans are nearing the maximum life span. If that were the case, you would expect any decreases in mortality rates in younger ages to be accompanied by mortality rates that increase more rapidly with age, to preserve the age limit, he explained. 

The researchers found that this was generally the case among those born before 1900. However, the mortality rate trends in people born between 1910 and 1950 appear to be different. This group reached the old age-related plateau at older ages than the pre-1900s group had, and they didn’t see sudden upticks in mortality at old ages to accompany decreases in mortality seen at younger ages. This finding hints we have not reached the maximum human life span, McCarthy said.

“In most of the countries we examined, we project that the maximum age will rise dramatically in the future,” McCarthy said. “This will lead to longevity records being broken in the next 40 years or so.” RELATED STORIES—People who live to 100 have unique gut bacteria signatures

For example, the model projects that a Japanese woman born in 1919 or later has at least a 50% chance of living to age 122 or older. And a Japanese woman born in 1940 or later has a 50% chance of surpassing age 130. (The model roughly covered the next 50 years, and didn’t predict that anyone in any country would surpass age 150 in that time.)

However, the model has a major limitation: It does not account for the biology of aging. In other words, in predicting who has a decent chance of living past age 122, the model doesn’t account for the fact that people’s cells age over time and they become more prone to age-related diseases, like cancer. It also doesn’t acknowledge how advances in medicine might extend human life span in the years to come.   

“While we find this demographic analysis interesting, we have long believed that addressing basic questions about whether, when and how aging stops are best settled by research with large animal cohorts maintained under stable laboratory conditions,” Michael Rose (opens in new tab) and Laurence Mueller (opens in new tab) , professors at the University of California, Irvine, who were not involved in the study, told Live Science in an email.

“The duration of life is at its heart a biological phenomenon, not a mathematical one,” said Stuart Jay Olshanky (opens in new tab) , a professor of epidemiology and biostatistics at the University of Illinois Chicago who was not involved in the research. 

McCarthy accepts these limitations, but “since the simple model we used fit historical mortality data extremely well,” he said he thinks it can still offer useful insight into future mortality patterns.

Global markets have given Trump a clear no-confidence vote - and his fickleness is making the problem worse

Global financial markets gave a clear vote of no-confidence in President Trump’s economic policy.

The damage it will do is obvious: costs for companies will rise, hitting their earnings.

The consequences will ripple throughout the global economy, with economists now raising their expectations for a recession, not only in the US, but across the world.

Financial investors had been gradually re-calibrating their expectations of Donald Trump over the past few months.

Hopes that his actions may not match his rhetoric were dashed on Wednesday as he imposed sweeping tariffs on the US’ trading partners, ratcheting up protectionism to a level not seen in more than a century.

Markets were always going to respond to that but they are also battling with another problem: the lack of certainty when it comes to Trump.

He is a capricious figure and we can only guess his next move. Will he row back? How far is he willing to negotiate and offer concessions?

These are massive unknowns, which are piled on to uncertainty about how countries will respond.

China has already retaliated and Europe has indicated it will go further.

That will compound the problems for the global economy and undoubtedly send shivers through the markets.

Much is yet to be determined, but if there’s one thing markets hate, it’s uncertainty.

Hundreds of names removed from official Gaza war death list

Hundreds of names removed from official Gaza war death list

Gaza’s health ministry has removed 1,852 people from its official list of war fatalities since October, after finding that some had died of natural causes or were alive but had been imprisoned.

The list of deaths currently stands at 50,609 following the removals. Gaza’s health ministry records do not distinguish between civilians and combatants.

Almost all of the names removed (97%) had initially been submitted through an online form which allows families to record the deaths of loved ones where the body is missing.

The head of the statistics team at Gaza’s health ministry, Zaher Al Wahidi, told Sky News that names submitted via the form had been removed as a precautionary measure pending a judicial investigation into each one.

“We realised that a lot of people [submitted via the form] died a natural death,” Mr Wahidi said. “Maybe they were near an explosion and they had a heart attack, or [living in destroyed] houses caused them pneumonia or hypothermia. All these cases we don’t [attribute to] the war.”

Others submitted via the form were found to be imprisoned or to be missing with insufficient evidence that they had died.

Some families submitting false claims, Mr Wahidi said, may have been motivated by the promise of government financial assistance.

It is the largest removal of names from the list since the war began, and comes after 1,441 names were removed between August and October – 54% of them originating in hospital morgue records rather than the online form.

Mr Wahidi says his team audited the hospital data after receiving complaints from people who had ended up on the list despite being alive.

They found that hospital clerks, when operating without access to the central population registry and lacking full names or dates of birth for the dead, had marked the wrong people as dead in their records.

In total, 8% of people who were listed as dead in August have since been removed from the official death toll. Many of those may later be added back in, as the judicial investigations proceed.

‘It doesn’t look like manipulation’

Gabriel Epstein, a research assistant at US thinktank The Washington Institute for Near East Policy, said there’s no reason to think the errors are the result of deliberate manipulation intended to inflate the share of women and children among the dead.

“If 90% of the removed entries were men aged 18-40, that would look like manipulation,” he said. “But it doesn’t look like that.”

Of those entries removed since the start of the war and whose demographic information was recorded, 41% are men aged 18 to 60, while 59% are women, children and elderly people.

By comparison, 44% of remaining deaths are working-age men. This means that the removals have had the effect of slightly reducing the share of women and children in the official list.

Names were previously added to the list without verification

Until October, Mr Wahidi said, names submitted via the online form had been added to the official list of registered deaths before undergoing a judicial confirmation process.

The publication of unverified deaths submitted via the form had previously led to issues with the data, with 1,295 deaths submitted via the form being removed from the list prior to October. This included 474 people who were later added back again.

Sky News previously understood that names from the form were only published after undergoing judicial confirmation. However, Mr Wahidi says this practice only began in October.

“This does cause me to downgrade the quality of the earlier lists, definitely below where I thought they were,” said Professor Michael Spagat, chair of Every Casualty Counts, an independent civilian casualty monitoring organisation.

A Ministry of Health document from July 2024 confirms that names submitted through the online form were, at the time, included in the official fatality list before being verified.

These names “are initially included in the final count of martyrs, but verification procedures are undertaken afterward”, the document says.

“They basically said that they were posting these things provisionally pending investigation,” said Prof Spagat.

“There may have been literally zero people, including us, who actually absorbed this message, but they weren’t hiding it either.”

More than 1,200 Israelis have been killed in the 7 October attack and ensuing war.

Children among 19 killed in Russian attack on Zelenskyy's home city

At least 19 people, including nine children, have been killed in a Russian attack on Volodymyr Zelenskyy’s home city, according to Ukrainian officials.

Around 50 people were also wounded in the attack, according to emergency services, and regional governor Serhiy Lysak said more than 30, including a three-month-old baby, were in hospital.

Ukraine’s president said Friday’s attack on Kryvyi Rih showed Russia “does not want a ceasefire”.

“The whole world sees it,” said Mr Zelenskyy.

“Every missile, every strike drone proves that Russia only wants war.

“And only on the pressure of the world on Russia, on all efforts to strengthen Ukraine, our air defence, our forces – only on this does it depend when the war will end.”

Russia’s defence ministry claimed it had struck a military gathering – a statement denounced by the Ukrainian military as misinformation.

Mr Lysak wrote on the Telegram messaging app that 18 people were killed when a missile hit residential areas and sparked fires.

Later on Friday, Russian drones attacked homes and killed one person, Oleksandr Vilkul, the city’s military administrator, said.

Local authorities said the missile strike damaged about 20 apartment buildings, more than 30 vehicles, an educational building and a restaurant.

They said emergency responders were at the scene and psychologists were helping survivors.

Confirming the “high-precision strike”, the Russian defence ministry said on Telegram it targeted “a meeting of unit commanders and Western instructors” in a city restaurant.

“As a result of the strike, enemy losses total up to 85 servicemen and officers of foreign countries, as well as up to 20 vehicles,” the ministry added.

US ‘not interested in negotiations about negotiations’

It comes after the US secretary of state issued a veiled threat to Russia as talks about a ceasefire with Ukraine continue.

Speaking in Brussels during a NATO meeting, Marco Rubio said the US was “not interested in… negotiations about negotiations”.

“We’re testing to see if the Russians are interested in peace. Their actions – not their words, their actions – will determine whether they’re serious or not, and we intend to find that out sooner rather than later,” he said.

In March, the US agreed a proposed 30-day ceasefire with Ukraine after talks in Saudi Arabia. Later, Washington negotiated a limited ceasefire about energy infrastructure with Russia.

Since then, the warring countries have accused each other of violating the energy ceasefire.

UK Foreign Secretary David Lammy, who was also in Brussels on Fridaym said Vladimir Putin “continues to obfuscate, continues to drag his feet” on ceasefire talks.

He added that while the Russian president should be accepting a ceasefire, “he continues to bombard Ukraine, its civilian population, its energy supplies”.

“We see you, Vladimir Putin. We know what you are doing,” he said.
