"Loppem Castle", located in Loppem (West-Vlaanderen), Belgium, is a 19th-century neo-gothic castle commissioned by Baron Charles van Caloen and his wife Savina de Gourcy Serainchamps. Construction began in 1856 under English architect Edward Welby Pugin and was completed by Belgian architect Jean-Baptiste Bethune, who infused it with Flemish character. The castle retains its original architecture and interior. It houses an extensive art collection, including a circa 1460 stained-glass Pietà, and is surrounded by a park featuring ponds and a maze.

Komodo dragons are apex predators and their diet includes sea turtles.

This is the birth of a Seahorse.

The perfect combination of buoyancy and bone density allows them to “fly” through water at speeds of 5 mph (8 kph), propelling themselves using intermittent contact with the ground, like astronauts on a moonwalk.

Hippos can't technically swim

When a crow isn’t feeling well, it lands near an ant nest, spreads its wings and… stands there, still, letting the ants climb onto its body.
But why?
The ants release formic acid, a natural substance with antiparasitic properties. This “chemical bath” helps eliminate fungi, bacteria and parasites from the skin and feathers.
This behavior is so common that it even has a name: “anting.” And it’s not just among crows — several species of birds do this as a form of self-medication.
Nature is a living pharmacy. And animals know exactly where to look for a cure.

Researchers have detected, for the first time, gases on another planet that — here on Earth — only arise because of living beings.

The discovery was made with the world's most advanced space telescope : o James Webb.

![](https://m.stacker.news/87548)

🔭 The telescope that made this possible

James Webb was launched in 2021 by NASA. It is the most powerful instrument we have ever sent into space.

He sees the universe with unprecedented precision — and now he has produced the most promising data in the history of astrobiology.


🌍 The planet that entered the radar: K2-18 b

Located 124 light years from Earth, it is 2.6 times larger than our planet.

Orbiting a small, cool star, it lies in a region called the habitable zone — where conditions allow liquid water on the surface.


🌊 A candidate for an ocean planet

Scientists hypothesize that K2-18 b is a planet covered by a liquid ocean, with an atmosphere rich in hydrogen.

An environment reminiscent of primitive Earth, where microbial life began to appear.


🧪 The gases that triggered the alert

In the planet's atmosphere, the following were found:
•Dimethyl sulfide (DMS)
•Dimethyl disulfide (DMDS)

Here on Earth, these gases are produced exclusively by living organisms, such as marine phytoplankton.



📈 Data too strong to ignore

These gases were detected in concentrations thousands of times greater than on Earth.

And the analysis has 99.7% statistical confidence — that is, only a 0.3% chance of the signal being the result of chance.

With what science knows today, there is no non-biological explanation for this.



⚠️ It's not a confirmation of life yet — but it's the closest we've come

The study talks about biosignature: a possible trace of biological activity.

It's the kind of signal scientists have always dreamed of finding on exoplanets. Now it's here, published in the Astrophysical Journal Letters.



🧬 What kind of life could it be?

No intelligent aliens. The bet is on simple microbial life, similar to that of Earth's primitive oceans.

Still, it would be the first form of life identified outside the solar system.



What makes this discovery unique

More than 5,800 exoplanets have already been cataloged.

But this is the first time that carbon-based molecules — essential for life — have been detected in the atmosphere of a habitable planet.

It's a game changer.



🛰️ The search for life has become data science

The study author summarized:

“We have entered the era of observational astrobiology.”

The search for life is no longer just philosophy or science fiction. It is now spectroscopy, statistics and scientific inference.

And the frontier of the unknown has just receded.

Science may have found life outside Earth 👽

Taq Kasra holds a prominent place in history as one of few remnants of the great city of Ctesiphon, the capital of Parthian and Sassanian Empires. Its construction is believed to have been initiated during the rule of Ardeshir I, founder of the Sassanian Empire, 3rd Century AD. This period marked a renaissance in Persian architecture, with a distinct focus on monumental structures that exemplified the power and cultural identity of the empire.

It was built in 6th Century AD. It is the world’s largest brick vault and largest free-standing arch constructed until modern times. The arch stands as a symbol of architectural prowess, with its grand semi-circular design and intricate embellishments. The central arch spans over 25m, making it one of largest single-span arches in the world. The intricate brickwork, both exterior and interior, showcases the mastery of the craftsmen who meticulously placed each brick to create a harmonious blend of form and function. 

Taq Kasra’s architectural significance lies not only in its grandeur but also in the ingenious design elements that make it a true masterpiece of Persian architecture. The arch’s semi-circular form, a hallmark of Persian arches, symbolizes the union of heaven and earth, reflecting the spiritual and earthly realms of Persian cosmology. This design choice imparts a sense of harmony and balance to the structure, echoing philosophical and cultural ideals of the Persian civilization.

The exterior of Taq Kasra adorned with intricate ornamentation that showcases the Persian artisans’ mastery of decorative art. Floral motifs, geometric patterns, and inscriptions are meticulously carved into the brickwork, creating a visual narrative that celebrates the empire’s achievements, its rulers, and its connection to the divine. The facade’s intricate embellishments are a testament to the Persian love for beauty and aesthetics, which permeated all aspects of their culture.

The interior of Taq Kasra is equally captivating. The use of deep niches and recesses along the walls not only adds structural stability but also creates a sense of depth and dimension within the arch. The interplay of light and shadow enhances the arch’s three-dimensional effect, capturing eye and evoking a sense of wonder. This manipulation of architectural elements to evoke emotions is a quintessential characteristic of Persian architecture, where form and function converge to create an immersive experience for visitors.

The arch’s towering height and colossal scale are balanced by its elegant proportions, a hallmark of Persian architectural aesthetics. This careful attention to proportion and symmetry reflects the Persian emphasis on creating spaces that resonate with the human spirit and provide a sense of order in the universe. As visitors stand beneath the arch, they are not just witnesses to a physical structure; they are enveloped in an architectural embrace that carries echoes of a rich cultural legacy.

Taq Kasra stands as an embodiment of Persian architectural brilliance, where form, function, symbolism, and aesthetics seamlessly intertwine. Its grandeur speaks to the power and influence of the Persian Empire, while its intricate detailing and design reflect the cultural sophistication of the civilization. As we gaze upon Taq Kasra today, we are transported to a time when Persian architects crafted not just structures but living embodiments of their culture, leaving an indelible mark on the landscape of history.

During the construction of the Antakya Museum Hotel in Türkiye 🇹🇷, workers unearthed a breathtaking archaeological marvel: the largest intact mosaic in the world. Spanning an impressive 1050 square meters, this ancient mosaic once adorned a significant public building in the historic city of Antioch.

Archaeologists believe the mosaic, dating back to 6th Century AD, was possibly part of a government building. Inside, artifacts dating to the Hellenistic Age (beginning in 323 BC) were discovered alongside the mosaic's intricate geometric and figural designs, offering a glimpse into the artistic sophistication of the period.

Rather than relocating this massive masterpiece, the hotel was ingeniously designed to float above it, incorporating special platforms and viewing points that allow guests to admire this extraordinary relic from the past.

Cats have a greater number of bones than humans. While the human body has 206 bones, cats have around 230 bones, and this number can vary slightly depending on the breed and individual characteristics.
The difference is mainly in the spine and ribs. Cats have a very flexible spine, made up of more movable vertebrae, which contributes to their agility and ability to move so easily. In addition, they have more bones in their tails, which are also long and flexible, allowing for greater control and balance during rapid movements.
The greater number of bones is also related to the bones in the paws, especially at the ends of the hind legs and in the claws, which give them a unique ability to climb and hunt.
This specialized bone structure is one of the many characteristics that make cats so agile and adaptable.
