Robots inspired by sea cucumbers turn from liquid into solid

Shape-shifting robots inspired by sea cucumbers can rapidly change between liquid and solid, offering the possibilities of breakthrough treatments in medicine, new research shows.

The miniature robots could be used in surgery and might change the face of engineering, researchers said.

Traditional robots are hard-bodied and stiff, while “soft” robots have so far been flexible but weak, and difficult to control.

The sea cucumber can transform itself from solid into a liquid. They liquefy at will to pour their bodies into tight spaces and solidify again to hide from predators.

“Giving robots the ability to switch between liquid and solid states endows them with more functionality,” said Chengfeng Pan, an engineer at the Chinese University of Hong Kong, who led the study.

Researchers put their robots through an obstacle course of mobility and shape-morphing tests in a study, which was published on Wednesday in the journal Matter.

The team created a new material — called the “magnetoactive solid-liquid phase transitional machine” — by embedding magnetic particles in gallium, a metal with a very low melting point of 29.8°C.

They have also tested the material’s mobility and strength in a variety of contexts.

The robots jumped over moats, climbed walls and split in half to co-operatively move other objects around before joining back together.

In one video, a robot shaped like a person liquefies to ooze through a grid before reforming.

“Now, we’re pushing this material system in more practical ways to solve some very specific medical and engineering problems,” Mr Pan said.

On the biomedical side, the team used the robots to remove a foreign object from a model stomach and to deliver drugs on-demand into stomach.

They also demonstrate how soldering robots can ooze into hard-to-reach circuits and the can be a mechanical “screw” for assembling parts in hard-to-reach spaces.

“Future work should further explore how these robots could be used within a biomedical context,” said senior author and mechanical engineer Carmel Majidi of Carnegie Mellon University.

“What we're showing are just one-off demonstrations, proofs of concept, but much more study will be required to delve into how this could actually be used for drug delivery or for removing foreign objects.”

Tips to stay safe during hot weather
  • Stay hydrated: Drink plenty of fluids, especially water. Avoid alcohol and caffeine, which can increase dehydration.
  • Seek cool environments: Use air conditioning, fans, or visit community spaces with climate control.
  • Limit outdoor activities: Avoid strenuous activity during peak heat. If outside, seek shade and wear a wide-brimmed hat.
  • Dress appropriately: Wear lightweight, loose and light-coloured clothing to facilitate heat loss.
  • Check on vulnerable people: Regularly check in on elderly neighbours, young children and those with health conditions.
  • Home adaptations: Use blinds or curtains to block sunlight, avoid using ovens or stoves, and ventilate living spaces during cooler hours.
  • Recognise heat illness: Learn the signs of heat exhaustion and heat stroke (dizziness, confusion, rapid pulse, nausea), and seek medical attention if symptoms occur.

Day 3, Abu Dhabi Test: At a glance

Moment of the day Just three balls remained in an exhausting day for Sri Lanka’s bowlers when they were afforded some belated cheer. Nuwan Pradeep, unrewarded in 15 overs to that point, let slip a seemingly innocuous delivery down the legside. Babar Azam feathered it behind, and Niroshan Dickwella dived to make a fine catch.

Stat of the day - 2.56 Shan Masood and Sami Aslam are the 16th opening partnership Pakistan have had in Tests in the past five years. That turnover at the top of the order – a new pair every 2.56 Test matches on average – is by far the fastest rate among the leading Test sides. Masood and Aslam put on 114 in their first alliance in Abu Dhabi.

The verdict Even by the normal standards of Test cricket in the UAE, this has been slow going. Pakistan’s run-rate of 2.38 per over is the lowest they have managed in a Test match in this country. With just 14 wickets having fallen in three days so far, it is difficult to see 26 dropping to bring about a result over the next two.

Retirement funds heavily invested in equities at a risky time

Pension funds in growing economies in Asia, Latin America and the Middle East have a sharply higher percentage of assets parked in stocks, just at a time when trade tensions threaten to derail markets.

Retirement money managers in 14 geographies now allocate 40 per cent of their assets to equities, an 8 percentage-point climb over the past five years, according to a Mercer survey released last week that canvassed government, corporate and mandatory pension funds with almost $5 trillion in assets under management. That compares with about 25 per cent for pension funds in Europe.

The escalating trade spat between the US and China has heightened fears that stocks are ripe for a downturn. With tensions mounting and outcomes driven more by politics than economics, the S&P 500 Index will be on course for a “full-scale bear market” without Federal Reserve interest-rate cuts, Citigroup’s global macro strategy team said earlier this week.

The increased allocation to equities by growth-market pension funds has come at the expense of fixed-income investments, which declined 11 percentage points over the five years, according to the survey.

Hong Kong funds have the highest exposure to equities at 66 per cent, although that’s been relatively stable over the period. Japan’s equity allocation jumped 13 percentage points while South Korea’s increased 8 percentage points.

The money managers are also directing a higher portion of their funds to assets outside of their home countries. On average, foreign stocks now account for 49 per cent of respondents’ equity investments, 4 percentage points higher than five years ago, while foreign fixed-income exposure climbed 7 percentage points to 23 per cent. Funds in Japan, South Korea, Malaysia and Taiwan are among those seeking greater diversification in stocks and fixed income.

How Filipinos in the UAE invest

A recent survey of 10,000 Filipino expatriates in the UAE found that 82 per cent have plans to invest, primarily in property. This is significantly higher than the 2014 poll showing only two out of 10 Filipinos planned to invest.

Fifty-five percent said they plan to invest in property, according to the poll conducted by the New Perspective Media Group, organiser of the Philippine Property and Investment Exhibition. Acquiring a franchised business or starting up a small business was preferred by 25 per cent and 15 per cent said they will invest in mutual funds. The rest said they are keen to invest in insurance (3 per cent) and gold (2 per cent).

Of the 5,500 respondents who preferred property as their primary investment, 54 per cent said they plan to make the purchase within the next year. Manila was the top location, preferred by 53 per cent.
