Scientists have created a tiny “Terminator 2”-like robot that can melt and resolidify itself on command, enabling it to easily escape from confined spaces.

To make the phase-shifting robot, scientists embedded microscopic chunks of magnetic neodymium, boron and iron into liquid gallium (a metal with a low melting point) and left it to solidify.

And just like the spine-chilling T-1000 from “Terminator 2,” the robot has shape-shifting abilities that make it an excellent escape artist. By using magnets to command their miniature creation to melt, the researchers recorded the robot transforming into an amorphous puddle to slither through the bars of a cage before miraculously reconstituting itself on the other side. The researchers published their findings Jan 25 in the journal Matter (opens in new tab) .

To perform this melting trick, the researchers heated the bot through a process known as magnetic induction — using a moving magnet to set up an electrical current inside the robot. The current melted the gallium, and the magnetic elements suspended inside caused it to be drawn toward the magnet. RELATED STORIES—This sideways-scooting robot crab is so tiny, it fits through the eye of a needle

“The magnetic particles here have two roles,” senior author Carmel Majidi (opens in new tab) , a mechanical engineer at Carnegie Mellon University, said in a statement (opens in new tab) . “One is that they make the material responsive to an alternating magnetic field, so you can, through induction, heat up the material and cause the phase change. But the magnetic particles also give the robots mobility and the ability to move in response to the magnetic field.”

The researchers said the inspiration for the device came from sea cucumbers, which have been observed switching between soft and stiff states to protect themselves from their environment and increase the weight they can carry.

The researchers see several potential medical and technological applications for their robot. So far, it has passed multiple tests: fixing circuits by entering tough-to-reach spots and then transforming itself into solder; melting into a screw socket and then solidifying to become a mechanical screw; and removing a foreign object from a model stomach.

“Giving robots the ability to switch between liquid and solid states endows them with more functionality,” lead author Chengfeng Pan (opens in new tab) , an engineer at The Chinese University of Hong Kong, said in the statement. “Now, we’re pushing this material system in more practical ways to solve some very specific medical and engineering problems.”

UK economy contracts – with record fall in exports to the US after Trump tariff hikes

UK economy contracts - with record fall in exports to the US after Trump tariff hikes

The UK economy shrank more than expected in April as the worst of President Trump’s tariffs hit.

The standard measure of economic output (GDP) contracted a sharp 0.3% in April, data from the Office for National Statistics (ONS) showed.

During the month, Mr Trump’s so-called “Liberation Day” applied steep tariffs to countries around the world and sparked a trade war with China, the world’s second-largest economy.

The outcome is worse than expected by economists. A contraction of just 0.1% had been forecast by economists polled by the Reuters news agency.

It’s also down from the growth of 0.2% recorded in March.

Blow for Reeves

It’s also bad news for Chancellor Rachel Reeves, who has made the push for economic growth her number one priority. Speaking to Sky News following the news, she described the figures as “disappointing”.

Reeves refuses to rule out tax rises

Additional costs on businesses were also levied during the month, as higher minimum wages and employer national insurance contributions took effect, which businesses told the ONS played a part in their performance.

Why?

The biggest part of the economy, the services sector, contracted by 0.4%, and manufacturing dropped 0.9%.

There was the largest ever monthly fall in goods exported to the United States, the ONS said.

Decreases were seen across most types of goods due to tariffs, it added.

Higher stamp duty depressed house buying and meant legal and real estate firms fared badly in the month.

After a strong showing in the first three months, car manufacturing performed poorly.

Economy shock overshadows Reeves' big day

Sky News’ Sam Coates and Politico’s Anne McElvoy serve up their essential guide to the day in British politics.

Rachel Reeves has said this morning that the latest figures showing the UK economy has shrunk by more than expected are “disappointing”. How much will this overshadow yesterday’s major spending announcement?

The chancellor has now planted Labour’s fiscal flag in the sand – and spending mistakes from here on in certainly cannot be blamed on their predecessors. How will Labour react to a potential internal revolt over disability benefit cuts? And how will the party manage the politics around expected tax rises in the autumn?

Did ChatGPT get the spending review right? Treasury minister gives his verdict

The chief secretary to the Treasury has called the Sky News-Chat GPT spending review projection “pretty good” and scored it 70%.

Darren Jones compared the real spending review, delivered by Rachel Reeves on Wednesday, and the Sky News AI (artificial intelligence) projection last week.

Sky News took the Treasury’s spring statement, past spending reviews, the ‘main estimates’ from the Treasury website, and the Institute for Fiscal Studies’ projections, and put them into ChatGPT, asking it to calculate the winners and losers in the spending review.

This was done 10 days ahead of the review – before several departments had agreed their budgets with the Treasury – on the basis of projections based on those public documents. It also comes amid a big debate kicked off by Sky News about the level of error of AI.

The Sky News-AI projection correctly put defence and health as the biggest winners, the Foreign Office as the biggest loser, and identified many departments would lose out in real terms overall.

It suggested the education budget would be smaller than it turned out, but correctly highlighted the challenges for departments like the Home Office and environment.

AI writes the spending review

Reviewing the exercise, the author of the real spending review told Sky News that this pioneering use of AI was “pretty, pretty good”.

He added: “I could be out of a job next time in 2027, which to be honest, it’s not a bad idea given the process I’ve just had to go through.”

The Treasury made a number of accounting changes to so-called “mega projects” which AI could not have anticipated, and changed some of the numbers.

Sky’s economics editor Ed Conway takes a look at the key takeaways from chancellor Rachel Reeves’ spending review.

Asked to give it a score, Mr Jones replied: “I’m going to give it 70%.”

The spending review includes AI as a tool to save money in various government processes.

Asked if 70% accuracy is good enough for government, he replied: “Well we’re not using your AI. We’ve got our own AI, which is called HMT GPT, and it helps us pull together all the information across government to be able to make better, evidence-informed decisions.”
