​Extreme Animals Alive is a special exhibition at the Houston Museum of Natural Science, a 501(c)(3) nonprofit organization. The unique exhibit features live animals with "superpowers," including the ability to change shape, glow, or even control the minds of other animals. One of the exhibit's most interesting creatures is the axolotl.

The axolotl is a species of paedomorphic mole salamander. Axolotls differ from many other amphibians in that they mature into their adult form without going through a metamorphic period. Furthermore, the adults remain fully aquatic and sport external gills.

Adult axolotls reach sexual maturity between 18 and 27 months, at which point they may reach up to 18 inches in length, though 9 to 12 inches is more common. They closely resemble salamander larvae, partly because they do not lose their external gills, like most salamander species. Axolotls also have vestigial teeth, which usually only occur in salamanders going through metamorphosis.

Wild axolotls usually appear brown or tan with a lighter undertone. However, they can change their color for camouflage, and researchers have noted several common color mutations, including pale pink with black eyes and white with red eyes.

The species originated in a system of lakes and wetlands in the Mexican highlands, along with smaller lakes throughout Xochimilco, Chalco, and other nearby waterways. Spanish settlers destroyed much of the animal's habitat following the conquest of the Aztec Empire, leaving the remaining population confined to areas around Mexico City. Despite losing a significant stretch of habitat, axolotls persisted in sufficient numbers to become a staple of the native Mexican diet during colonial times.

In modern times, the axolotl continues to face many challenges, including water pollution and threats from invasive species such as carp and tilapia. As a result, the axolotl qualifies as a Critically Endangered species, meaning it is nearly extinct in the wild. According to the International Union for Conservation of Nature, just 50 to 1,000 axolotls remain in the wild.

In captivity, meanwhile, the axolotl maintains a sizable population, largely due to the global scientific community's fascination with the animal's ability to regenerate limbs, gills, and even its eyes, heart, and central nervous system, including parts of the brain. Rather than scarring, the axolotl's body regenerates tissue over months. Researchers have also discovered that the axolotl's body readily accepts transplants from other individuals.

Axolotl regeneration can have several results. For example, if an animal's limb is damaged, the body may simultaneously grow a new limb and repair the original limb, resulting in an axolotl with extra arms or legs. Axolotls can regenerate more easily in youth, but do not lose the ability with age. While scientists do not fully understand the animal's ability to regenerate, they sometimes attribute it to the axolotl's indeterminate growth, meaning its body continues to grow throughout its lifetime.

As mentioned, the axolotl also attracts scientists, researchers, and animal lovers for its neoteny. Many amphibian species begin life as fully aquatic animals, undergo metamorphosis, and then lose their gills as they assume a more terrestrial form. The term "neoteny" means that the axolotl reaches sexual maturity without undergoing metamorphosis, maintaining its gills and living its entire life in water.

​Some archeological discoveries are intentional, while others are accidental. Either way, archeologists typically work to carefully preserve the historical objects they unearth. Artifact preservation safeguards archeological finds, ensuring availability and accessibility for future generations.

When archeologists discover ancient pottery, for example, they document their discoveries with photos, videos, and reports. Next, they may establish when the object was used. From there, they classify the object under its respective category, such as Renaissance pottery. They may also display the artifact at a museum for entertainment, education, or research purposes.

Before scientists can do anything to an object, they evaluate it to determine its condition and outline the necessary preservation techniques. Some artifacts are recovered in their original state, while others are damaged or incomplete. The latter are typically repaired to restore them to the extent possible.

Most items require cleaning before storing. The cleaning method also depends on the artifact in question. A popular cleaning method for cleaning metal is electrolysis, which removes rust.

Next comes preservation. This helps maintain an object’s integrity while preserving it for posterity. Preservation techniques like resin coating and desalination stabilize damaged objects, preventing further degradation.

Preservation techniques depend on the object’s material. Popular techniques include vacuum-sealing, freezing, and chemical treatment. Organic artifacts such as plants, wood, and textiles may require storage where temperature, humidity, and light are carefully controlled. This protects objects against damage from environmental and biological factors, such as mold.

Records are also an important part of archeology, as they allow researchers to make sense of historical objects. Assigning each object an identification number through cataloging is necessary for accessibility and tracking purposes.

The more detailed an artifact’s documentation, the richer its context. Records should provide information on the location and condition of the find, restoration, cleaning, and preservation work conducted. They should also include any data that might enrich the finding’s context, such as topographical maps of the area and geographic information systems data.

Some historical finds deteriorate despite even the best preservation efforts, a reality that archeologists must contend with. In this case, digitization techniques can be helpful. With technology like 3D imagery, scientists can reconstruct archeological sites and artifacts. They can also preserve them virtually. For example, by digitizing the Gunboat Philadelphia (the oldest American fighting vessel), the Smithsonian American Art Museum documented minute areas of damage and other structural changes to the vessel (which was recovered in 1935 with much of its equipment intact).

Light projection is another technique that is used. Harvard Art Museum collaborated with the University of Basel and MIT to develop software that generates faded paintings’ original colors, which are then projected via low-intensity light onto the original material, virtually restoring it. Such a technology could bring back to public view writings and paintings that are too fragile for restoration by traditional methods.

Not all historical finds make it to museums’ public galleries. However, modern technologies can increase accessibility to these artifacts. Thanks to virtual reality, audiences can experience a 3D image of an object remotely. Such technologies also help address ethical concerns. Balancing public accessibility with the cultural significance of some objects can be challenging. With virtual reality, global audiences can experience history without the objects ever leaving their places of origin.

Artifact preservation is critical for several reasons. It conserves history and cultural heritage while providing humans with tangible links to the past. It also offers immense research opportunities, as future researchers can leverage advances in archeological research to open new lines of inquiry and develop new perspectives.

​The intellectual streams of the ancient Middle East were firmly rooted in religious cosmology and thought, forming a rich tapestry that influenced Western civilization for centuries. From the fertile Mesopotamian valleys to the banks of the Nile, early civilizations developed advanced conceptual frameworks to address existential questions about life, divinity, and humanity.

At the heart of Middle Eastern philosophy was the concept of the sacred, where divine agency existed in every realm of life and nature. According to this worldview, everything earthly had a divine prototype, ensuring easy continuity between the worldly and sacred spheres. The Mesopotamians, for instance, believed that the universe was created by introducing order into chaos, a frequent theme in numerous later philosophical and religious traditions.

One of the earliest and most significant philosophical systems to emerge from this region was Zoroastrianism, founded by the Iranian prophet Zarathustra between 1700 and 1800 BCE. Zoroastrian philosophy introduced a rich ethical dualism that would influence many later philosophical traditions. It was the first system to address the problem of evil in metaphysical terms, proposing a conflict between good and evil powers in a monotheistic framework. This metaphysical innovation would later shape Jewish, Christian, and Islamic philosophy.

The Babylonians developed philosophical traditions that went beyond descriptive observation to provide systems of reason and rationale. Their philosophical treatises, such as "Dialog of Pessimism," possessed strikingly similar features to those of post-Greek writings, suggesting possibly some influence over Western philosophy. The dialectic structure of the text was similar to the dialogue technique of Plato and Socrates.

In ancient Egyptian philosophy, the divine-human relationship was particularly advanced. The Egyptians possessed abstract ideas about the afterlife that were linked to ethical behavior in this life. Ma'at, the concept of truth, justice, and cosmic order, was part of their philosophical framework and influenced both practical rule and metaphysical theory.

The ancient Middle East also saw the emergence of various schools of philosophy that explored the essence of light and wisdom. These included Manichaeism, which used Zoroastrianism's dualistic framework, and Zurvanism, which used time as an original creator and explored various means of comprehending reality in terms of aesthetic, materialist, and fatalistic approaches.

The relationship between religion and science in ancient Middle Eastern philosophy was particularly important. Rather than seeing them as separate fields of study, ancient thinkers integrated astronomical observations, mathematical axioms, and religious ideas into coherent systems of thinking. Numbers were not only useful but also spiritually important.

Other modes of literature, including epic poetry, literature of wisdom, and religious works, transmitted and sustained these philosophical schools. The contrast between sacred and secular philosophy also often remained ill-defined, as can be seen in texts such as the epic of Gilgamesh, which combines religious narrative and philosophical speculation.

The influence of Middle Eastern philosophy transcended its era and geographic boundaries. Its impact is evident in Greek philosophy, the Abrahamic religions, and contemporary philosophical thought. The sophisticated ways in which these early thinkers explored questions of existence, morality, and the relationship between the divine and human realms continue to shape modern philosophical inquiry.

​A museum curator is someone who is employed by a museum to handle and arrange exhibits, collections, and other items meant to be displayed in the museum. They also oversee and preserve the collections and artifacts, ensuring their integrity and condition.

Museum curators can provide details and create exhibits that make visitors' experiences enjoyable and help them navigate the museum. They might also be involved in activities such as fundraising, promoting the museum, managing its public image, and developing educational initiatives related to the institution.

The main duty of a curator is to manage the collections held in a museum; so the word "curator" comes from the Latin verb "curare," meaning "to care for," and has evolved significantly in the last 25 years.  It now includes both the traditional role of managing collections in museums and overseeing departments in large museums.

Museums employ several professionals, including exhibit designers, fundraisers, conservators, collections managers, educators, and museum directors. Curators serve as pivotal figures who work together with all these staff members. A museum's limited storage space necessitates curators deciding which items are worthy of being acquired for its collections.

A museum curator's specific roles and duties can differ based on the museum's size. A museum curator who works for a smaller museum is likely to have a broader range of tasks and might also need to handle administrative or managerial roles alongside their curatorial work. While curators who work for larger museums often focus on a specific field of expertise, handling tasks that are exclusively connected to their area of specialization.

The role of a curator also involves creating themes for exhibitions and conducting research on the museum's collections and displays. Exhibit concepts are carefully mapped out over some time (as long as three years in some cases) to facilitate negotiations for borrowing artifacts from other museums or private collectors. Curators work closely with exhibition designers and educators to craft exhibits that captivate and educate the broader audience.

A museum curator is expected to possess several technical skills. These skills might range from research to project management, fundraising, collections management, and art collections skills. It is also important that the curator understands fine arts, museum displays, educational initiatives, and oral traditions. 

Collections management involves the systematic recording, safeguarding, and explanation of items crucial to fulfilling a museum's objectives. Curators use collections management to systematically list and categorize their artifacts, monitor where they are stored, and ensure their preservation.

Art collections consist of artworks assembled by either artists or curators. Museum curators use art collections for conducting studies, arranging public exhibitions, and showcasing artworks to audiences. They also work hand in hand with contract conservators to develop treatment plans for the artworks in their collections.

Another museum skill a curator must possess is museum exhibit skills. Museum exhibits showcase items and details within a museum setting. Curators are also responsible for creating and managing displays, as well as crafting descriptions on placards to explain them.

As a museum curator, you should be good at cataloging. Cataloging is the creation of entries for items or objects. Museum curators use cataloging methods to monitor and organize the artifacts within their collections. They input information into software applications, handle the processing and organization of newly acquired artifacts, and instruct volunteers on correct cataloging methods.

​The Middle East is home to some of the most fascinating archaeological sites in the world. Many of these sites attract thousands of tourists from across the globe every year. Because it is rich in history and culture, the Middle East is a must-visit destination for anyone who loves history and would love to explore the archaeological elements.

One of the most famous archaeological centers in the Middle East is the Pyramids of Giza. The pyramids are situated on the west bank of the Nile River, on a plateau known as the Giza Plateau. These pyramids were built in the 25th century BC, approximately between 2480 and 2550 BC. The largest and oldest pyramid on the Giza plateau is the Khufu. This pyramid comprises approximately 23 million stone blocks that weigh 2.5 tons each, and it took over 3800 years to build. In addition to the Pyramids of Giza, the Giza plateau is also home to the tombs of the kings of the Fourth Dynasty and the Sphinx, a creature with the body of a lion and the head of a human. The sphinx is usually described as the guardian of the plateau.

Further, located off the Mediterranean Sea on the topmost tip of Africa, Carthage is one of the most ancient cities in the world. Today, the city of Carthage is 15 kilometers from Tunis, the modern capital of Tunisia. Carthage was so powerful it built an empire that encompassed a huge swath of the western Mediterranean Sea. Today, the city of Carthage is home to some of the most fascinating archaeological museums with Carthage and Roman artifacts. Similarly, the Roman Houses Quarter contains several aristocratic monuments and buildings that the Romans constructed during their occupation of the city. The Roman theater of Carthage is famous to tourists for its semi-circular runways and its overall architectural beauty.

Also, Baylon is an archaeologically rich city that will fascinate travelers. Babylon was one of the most populated cities in ancient times. Among other things, the city is famous for its hanging gardens, the Ishtar Gate, and the Tower of Babel. All of these monuments are listed as ancient wonders of the world. Babylon was at the core of the success of ancient Mesopotamia, and it facilitated Babylonian trading and transport. Over time, the city of Babylon fell into ruins, and it is currently a UNESCO World Heritage Site situated near Baghdad in Iraq.

About 2,000 years old, Petra is one of the most ancient cities in the Middle East and is surrounded by sandstone cliffs and mountains. Petra houses some of the most fascinating architectural materials in the kingdom of Jordan and was named one of the Seven Wonders of the World in 2007. Some of the most fascinating elements of the city are its elaborate caved-in pink rocks. This architecture is symbolic of the various ancient civilizations that traded in and occupied Petra. Tourists often consider the monastery as the most fascinating of Petra’s rock-cut buildings. The monastery is also the largest carved mountain in the city. Another heavily visited site is the Nabataean Theater.

Similarly, in Saudi Arabia, there is a remote settlement named Hegra or Mada’in Saleh, which is about a thousand years old. Hegra was the second city of the Nabataean civilization after their capital city, Petra, in Jordan. It was an important trading post, connecting to several important trading routes around the Arabian peninsula. The city is home to 110 ancient tombs and inscriptions that are symbolic of the Nabataean artistic abilities. It is also the first Saudi Arabian destination to be named a UNESCO World Heritage Site.

​Each state in America has natural history museums that feature exhibits on animals, plants, ecosystems, geology, paleontology, and climatology. Some of the most famous of these venues include the Houston Museum of Natural Science, the National Museum of Natural History, the Natural History Museum of Los Angeles County, and the Denver Museum of Nature and Science.

The Houston Museum of Natural Science is one of the most renowned natural history museums in the United States.
