Scientists in Italy have demonstrated something that sounds impossible: light behaving like a solid, opening a new direction in quantum physics.

Researchers at the Italian National Research Council (CNR) and collaborating institutions created an unusual quantum state in which particles of light interacted collectively and developed properties associated with both liquids and solids.

The breakthrough involves a state of matter called a supersolid. In ordinary solids, particles arrange themselves into an organized structure. In superfluids, particles can move collectively with almost no resistance. A supersolid combines characteristics of both.

Normally, photons, the particles that make up light, do not interact strongly with one another. However, scientists can make light interact with matter inside specially designed semiconductor structures, creating hybrid particles called polaritons.

These particles contain properties of both photons and matter, allowing researchers to control their interactions in ways that would be impossible with ordinary light traveling through empty space.

By carefully adjusting the experimental conditions, the researchers observed an organized spatial pattern alongside the coherent behavior associated with a quantum fluid.

The experiment provides evidence that light-based systems can exhibit supersolid behavior, something previously studied mainly in ultracold atomic gases.

However, the researchers did not literally freeze a beam of pure light into a solid object. The experiment involved light interacting with matter, and the resulting state cannot be held or touched like an ordinary solid.

Scientists hope that understanding these unusual quantum states could eventually contribute to advances in quantum simulation, photonic technologies, and the study of exotic forms of matter.

The discovery demonstrates that light can behave in ways that go far beyond our everyday understanding of photons.

This is one of those ideas where an ordinary bench is doing much more than it looks like during the day.

In Germany, some bench-style shelter concepts are designed so they can unfold at night into a more protected sleeping space for people without a proper place to stay. Panels can close around the bench, thermal curtains help keep the inside warmer, and small solar-powered lights give basic light without needing a full power connection.

I think the smart part is that the structure still works as normal public furniture when it is not being used for sleeping.

Then at night, the same space can give someone a little more privacy and protection instead of leaving them completely open to cold air and weather.

It is not a full home, and it does not solve the bigger housing problem by itself. But honestly, even a small covered space can make a very different kind of night for someone who has nowhere else to go.

And this is why simple design matters sometimes.

Why should a bench only be a bench if it can also help someone rest a little better?

A polar bear sleeping peacefully on a small iceberg became one of the most loved wildlife photographs in the world. The image, titled "Ice Bed," was captured by British amateur photographer Nima Sarikhani during an expedition around Norway's Svalbard archipelago.

Sarikhani and his companions had searched for polar bears for days in thick fog before they finally came upon two of the animals. One of the bears climbed onto a small iceberg, used its powerful paws to carve out a comfortable hollow in the snow, and curled up to sleep. Sarikhani photographed the moment from the expedition vessel as the bear drifted off.

The picture went on to win the Wildlife Photographer of the Year People's Choice Award, chosen by the public from a shortlist, drawing the most votes among a record of roughly 75,000 wildlife-photography fans around the world.

Polar bears depend heavily on Arctic sea ice as a platform for hunting seals, for traveling, and for breeding. They are powerful swimmers, but as sea ice retreats, many populations are forced to spend more time on land or to swim ever greater distances. The photograph captured a completely natural, almost tender moment, a wild animal making itself a bed and going to sleep. But its setting also became a quiet reminder of just how closely the polar bear's life is bound to the frozen world around it.

Did this image stay with you the way it did for so many others? Tell us below. And here's one for today: what's a photograph of the natural world that you've never been able to forget?

China planted trees on such a huge scale that the result was not only more green land. The trees also started changing how water moves through some areas, and that part is actually very interesting.

One of the biggest examples is the Loess Plateau, where large restoration programs brought back trees, shrubs and other vegetation across a massive dry region. More plants meant more water moving from the land back into the air through evapotranspiration. New research shows that this extra moisture can also help the atmosphere produce more rain in some semi-dry areas, which can support water availability again.

But this is not as simple as saying more trees always means more water.

Trees also use a lot of moisture from the soil, and older studies from China found that heavy planting in dry areas can reduce local water supply if the number and type of trees do not match the rainfall there.

I think this is the most interesting part. Planting trees at this scale can actually change the local water cycle itself, but it has to be done carefully.

So yes, trees can help bring more moisture back into the system, but the right place and the right amount matters a lot too.
