Curious wolf pups emerge from their dens in Minnesota’s Voyageurs National Park, eager to explore their surroundings. Engaging in playful activities like roughhousing, these pups develop important social skills and gradually establish their place within the pack’s hierarchy.

Monitored by researchers from the Voyageurs Wolf Project, these pups contribute valuable insights into wolf behavior and their role within the pack structure. Despite facing challenges such as food scarcity, they adapt and thrive in their habitat.

The mummified remains of two-year-old Rosalia Lombardo rest in Palermo’s Capuchin Catacombs. Although she died of pneumonia in 1920, her body is remarkably preserved.

In the depths of an obscure Sicilian catacomb, there lies a young girl in an open casket. Her name is Rosalia Lombardo and she died at the tragically young age of two due to complications from pneumonia in 1920.

Her father was so grief-stricken that he sought the aid of an embalmer to preserve his child. The embalmer, Alfredo Salafia, then mummified Rosalia Lombardo so perfectly that her internal organs are still intact a century later.

Indeed, it is difficult to gaze upon the tiny body in the glass coffin and not believe that she will awaken at any moment. Her skin is still smooth and porcelain, and her golden hair is neatly tied back with a large, silk bow. And most hauntingly, her crystal blue irises are visible underneath her blonde eyelashes.

Michael Jackson’s physical appearance underwent changes over his career.

Starting with a natural Afro in the ‘70s as part of the Jackson 5, he later adopted a signature look with lightened skin and short curls, attributed to vitiligo.

His facial features also appeared to change over the years, often speculated to be the result of cosmetic surgeries.

WHY IS FUEL STORED IN THE WINGS OF THE AIRCRAFT

Fuel exclusively stored in the fuselage reduces aircraft performance, crash safety, and practicality. The FAA and EASA have regulations for fuel storage, but additional factors ultimately determine where fuel is stored within aircraft designs.
Fuel stored in the wing is generally safer in crash events than fuel stored near the passenger cabin. Even for crash events where the plane doesn’t catch on fire, fuel is best kept off and away from passengers. Fire kept away from the cabin (in the wings) gives passengers time to escape to safety.

Surprisingly, where fuel is stored within an aircraft can drastically effect the structural weight of the aircraft. This is due to a structural effect called span loading.
Imagine yourself walking onto a steadily thinning sheet of ice on a lake. Your steps start to crack the ice.

Quick, lay down flat and spread your weight out before you fall through. The thin ice can support your weight as long as you keep your weight spread out.
In this silly example, the ice thickness represents the thickness of structural aluminium or carbon fibre in a wing. The more evenly distributed the weight of the fuel, engines, components, and payload is across the wing, the thinner the “ice” – the aluminium in the wing can be to support the same weight.

Less aluminium equals less structural weight – resulting in lower cost, better efficiency, and higher aircraft performance. Fuel stored in the wing helps accomplish that.
Long range aircraft, like airliners, carry a large portion of their total weight as fuel – over 12%. Most of the fuel weight is burned up in flight. For huge airliners, that can be hundreds of thousands of pounds of fuel burned in one flight.

Aircraft simultaneously need their Center of Gravity (CG) tightly controlled and to be near and slightly ahead of the aerodynamic centre of the airplane. The CG is typically located near the wing. Slight movements in the CG – inches – have drastic impacts on aircraft stability and control. As a plane burns its fuel during flight, the CG needs to stay within a small range – the entire time.

Fuel stored in the wings is perfectly suited to keep the CG within limits as the weight of the plane reduces by tons.

Where do those checked bags go? Fuel in the fuselage limits how much baggage, cargo, cabin, and internal volume is available. Fuel is the perfect candidate to be put in the wings. It’s a liquid – which occupies odd geometries and narrow passages with ease. Fuel stored in the wings expands the amount of volume open for baggage as well as for passengers.

Fuel stored in the wings enables better safety, efficiency, performance, and affordability. With so many benefits to fuel storage in the wings, it would be irresponsible to not consider it.

1- Then and Now: Nineveh
Nineveh , Oldest and most populous city of ancient Assyria, on the eastern bank of the Tigris River opposite modern Mosul, Iraq. Its greatest development was under Sennacherib and Ashurbanipal in the 7th century BCE. It was captured and destroyed by Nabopolassar of Babylonia and his allies, the Scythians and Medes, in 612 BCE. Excavations made in 1845–51 revealed palaces, a library, city walls, and many gates and buildings.

2- Then and Now: Tyre
Tyre is a city in Lebanon, one of the oldest continually inhabited cities in the world,though in medieval times for some centuries by just a small population. It was one of the earliest Phoenician metropolises and the legendary birthplace of Europa, her brothers Cadmus and Phoenix, as well as Carthage’s founder Dido (Elissa). The city has many ancient sites, including the Tyre Hippodrome, and was added as a whole to the list of UNESCO World Heritage Sites in 1984.The historian Ernest Renan noted that ”One can call Tyre a city of ruins, built out of ruins .

3 - Then and Now: Carthage
.
Carthage was an ancient Phoenician city located on the northern coast of Africa. Its name means “new city” or “new town.” Before the rise of ancient Rome, Carthage was the most powerful city in the region because of its proximity to trade routes and its impressive harbor on the Mediterranean.

4 -Then and Now: Acropolis of Athens.

The Acropolis of Athens is an ancient citadel located on a rocky outcrop above the city of Athens, Greece, and contains the remains of several ancient buildings of great architectural and historical significance, the most famous being the Parthenon.

Then and Now: Persepolis
.
Founded by Darius I in 518 B.C., Persepolis was the capital of the Achaemenid Empire. It was built on an immense half-artificial, half-natural terrace, where the king of kings created an impressive palace complex inspired by Mesopotamian models. The importance and quality of the monumental ruins make it a unique archaeological site.

The physics of a pendulum wave
⠀
The dance comprises a 60-second cycle, with the longest pendulum completing 51 oscillations and each shorter pendulum having one additional oscillation than the previous.
Consequently, the 15th pendulum, the shortest, completes 65 oscillations. Although the pendulums initially fall out of sync due to their varied oscillation periods, after 60 seconds, they harmoniously return to their starting positions, prepared to repeat the synchronized dance.
