Humans can ‘feel’ objects buried in sand! Scientists reveal our secret ‘seventh sense’

It is our senses that help us define our reality. We see things, touch them, taste them, hear sounds, feel textures. Simple, right? But what if touch wasn’t just about actually touching? What if your hands could “feel” something before you even make contact?

That’s exactly what scientists are now calling a kind of “seventh sense.” Sounds wild, but it’s not sci-fi or magic. It’s just our body being smarter than we ever realised - a quiet skill we’ve had all along.

Humans can sense things without touching them

Researchers from Queen Mary University of London and University College London found that people can sense objects hidden under sand without actually touching them. Kind of like how birds on the beach somehow find food buried beneath the surface.

In one experiment shown at the IEEE ICDL conference, volunteers slowly ran their fingers through sand. Surprisingly, many of them could tell when something solid was buried underneath - even when the object was almost 3 cm away. That alone messes with what we think “touch” really means.

This ability is being called “remote touch.” Basically, when your fingers move through sand, tiny pressure waves bounce off hidden objects and change how the sand feels. Your skin picks up on these super subtle shifts. People in the study got it right about 70% of the time - which is honestly impressive for something most of us didn’t even know we could do.

Why are our hands so good at this?

Our fingertips are insanely sensitive. They notice the smallest changes in texture and resistance. The researchers found that human touch is almost as good as it can physically get - no fancy tools needed. Out of 216 tries, people correctly sensed hidden objects 79 times without even touching them properly.

No special bird beaks required. Just regular human hands doing quietly brilliant things.

Humans vs robots

Of course, scientists also tried this with robots. A robot arm trained with AI could sense objects from a similar distance, but it messed up a lot more. It was right only about 40% of the time and got confused by random noise in the sand.

Humans, on the other hand, were way better at filtering out “fake signals” and sticking to what actually mattered. Once again: humans 1, robots 0.

Why this actually matters

This research changes how we think about human perception. As Elisabetta Versace from Queen Mary University of London explained, it’s the first time scientists have shown that humans can sense things without direct contact, and that shifts how we understand our sensory world.

Another researcher, Zhengqi Chen, said this could help design better tools and tech in the future. Think prosthetic hands that feel more natural, or robots that can work safely in dangerous places.

Where this could be useful

This “remote touch” skill could help in real life too - like carefully digging at archaeological sites, finding people in collapsed buildings, or even helping robots explore places like the ocean floor or Mars.

So yes, we might not have superpowers. But it turns out our bodies are already doing some pretty superhero-level stuff - we just never noticed.
