Although small in size, ants could soon play a big role in protecting our health, reported The Daily Mail. The insects may one day be used to detect cancer, according to a new study. Scientists have discovered ants, like dogs, can "sniff" out the disease.

In various experiments dogs have detected different types – for example, finding breast and lung cancer by sniffing patients’ breath. But a study has now found ants have a "high potential" to be used as a form of detection.

Researchers discovered that after just a few minutes of training, formica fusca black ants were able to differentiate healthy human cells from cancerous ones in a petri dish. This, they believe, is because healthy and cancerous cells emit different compounds that ants can distinguish by smell.

Most people rely on an MRI, mammogram or blood tests, which can be expensive and invasive, to pick up cancerous cells.

The study, published in the journal iScience, is the first to show ants have high potential, are capable of learning very quickly, at lower cost, and are efficient.

The authors, from the French National Center for Scientific Research, said: "We show that individual ants need only a few training trials to learn, memorize, and reliably detect the odor of human cancer cells."

The target for suspected cancer patients to be seen by a specialist within two weeks of an urgent referral may be axed.

Instead, the NHS proposed a focus on diagnosis within 28 days of referral and treatment within 31 days of a decision as it began a consultation recently.

The discovery of high levels of bacteria has led the World Expo in Japan's Osaka to suspend daily water shows and use of a shallow play pool, organizers said.

It comes after visitors also complained that swarms of tiny flying insects had invaded the vast waterfront site where Expo 2025 runs until mid-October.

Nearly six million people have visited exhibits from more than 160 countries, regions and organizations since it opened in April.

Although polls showed that public enthusiasm for the Expo was lukewarm before its opening, organizers say crowds have been growing, especially in recent weeks, said AFP.

But concerns were raised over environmental conditions at the reclaimed island site in Osaka Bay, which was once a landfill.

Organizers said Thursday that high levels of legionella bacteria had forced them to close an area with shallow water where visitors, including children, could cool off.

That followed a statement released Wednesday saying daily fountain shows with music and lights at an artificial pond had been suspended for the same reason.

They said they were cleaning the affected areas, adding that a decision would come on Friday on whether the shows could resume.

Days before the Expo opened, a level of methane gas high enough to potentially ignite a fire was detected at the site.

More recently, organizers sprayed insecticide to deter swarms of non-biting midges bothering guests.

Also known as a World's Fair, the Expo phenomenon, which brought the Eiffel Tower to Paris, began with London's 1851 Crystal Palace exhibition.

It is now held every five years in different global locations.
