Delirium is an acute, transient, and typically reversible neuropsychiatric syndrome. The elderly have a risk of experiencing delirium.

Indicators of delirium include slow responses, worsened concentration, and confused perception, such as visual-auditory hallucinations. Changes in social behavior, including challenges in following requests, changes in communication, and moodiness and withdrawal, also indicate delirium.

Several factors contribute to delirium, including age-related cognitive decline and medications. Delirium is a psychiatric emergency that often involves dementia and a history of cognitive impairment. Addressing these multifactorial symptoms requires talking to the patient calmly, explaining who and where they are, and explaining the care provider's role. It also includes socialization pathways, such as arranging regular visits with friends and undertaking cognitively stimulating activities, such as reminiscences and conversations about daily life.

Individuals with delirium require monitoring until the symptoms subside. Essential care includes ensuring that the patient is safe and getting sufficient sleep and avoiding common issues such as falls and bed sores. Some patients benefit from psychiatric medications to help them overcome the confusion and disorientation associated with delirium. Physical restraints serve as a last resort, only undertaken when measures such as pharmacotherapy have failed, and harm-threatening behaviors persist, which become dangerous to the patient and those around them.

​One of the highlights at the Houston Museum of Natural Science’s Cullen Hall of Gems and Minerals is a 3,000-carat topaz crystal. Topaz is a crystalline mineral within the silicate group with fluorine within its chemical makeup. Topaz forms as igneous rock cools when volatile gaseous elements such as hydroxyl group (OH) and fluorine emit during volcanic degassing and later magma cooling stages.

Forming within cavities and fractures of rocks that have already cooled, such as granite, rhyolite, and pegmatite, topaz crystals expand as hot hydrothermal fluids flow through the rock cracks. In Australia, professionals have found the mineral in granite-derived placer deposits or gravel carried by streams.

Topaz has been revered since ancient times, with Ancient Egyptians associating the golden color of the gemstone with Ra, the Sun God, and ancient Greeks associating it with strength. With topaz mined during the Middle Ages in Germany’s Erzgebirge Mountains, the mining epicenter shifted to Brazil’s Minas Gerais region in the 1730s, and the industry there remains significant. Beyond its use for jewelry and ornaments, topaz serves as the basis of refractory materials that hold their strength under elevated temperatures and are thus useful for industrial applications in furnaces, incinerators, and reactors.

​Mineralogists hoping to find a vacation spot that doubles as an opportunity to scout minerals can explore countries in the Middle East. Many consider the Middle East a super region since it has a wealth of minerals.

Most know that the Middle East has a wealth of oil, a mineral; the Middle East also has a considerable concentration of iron ore, phosphates, zinc, copper, gold, and potash. Iron ore, used for steel production, has fueled the region’s industrial growth, as Iran, Oman, and Saudi Arabia have become the largest producers. Countries in the Middle East also contain large quantities of phosphates, used as fertilizer in agriculture. The reserves of phosphates reside in Morocco, Jordan, and Saudi Arabia.

Regarding zinc, Iran, Turkey, and Saudi Arabia hold the largest reserves, used in construction, the automotive industry, electronics, and medicine. Copper, a mineral used in electronics, electricity, and transportation, widely resides in Iran. The Middle East also has extensive reserves of the precious metal gold found in Iran, Saudi Arabia, and Turkey. Finally, Jordan contains large quantities of the mineral potash, used as a key ingredient fertilizer in the Middle East.

Other minerals found in the Middle East include sulfur, bauxite (an ingredient in aluminum production), and natural gas.

​Natural history museums have existed since the nineteenth century and are most prevalent in America and the Western world. The origins of these venues can be traced back to collections that were popular in Europe during the Renaissance. Referred to as cabinets of curiosities, they often contained a diverse array of objects including ecological specimens, scientific instruments, works of art, and artifacts. Over time, the concept of the museum has evolved, with dedicated institutions emerging to focus specifically on the study of natural history and the display of specimens.

One of the earliest natural history museums in America was established by Charles Wilson Peale, a prominent figure in early American naturalism. His museum was initially located in Philadelphia, and showcased a wide range of natural specimens alongside portraits of leaders of the American Revolution. This museum laid the groundwork for future institutions dedicated to the study of nature.

The Smithsonian Institution was founded in 1846, and played a pivotal role in the development of natural history museums in the United States. It initially served as a center for scientific research, but gradually expanded its focus to include displays and preserved items. Under the leadership of Spencer Baird, the Smithsonian's first curator, the institution amalgamated a vast collection of flora and fauna from around the globe.

Natural history museums of the nineteenth century were often shaped by the efforts of hunter-naturalists like John James Audubon and Theodore Roosevelt. These individuals combined a passion for hunting with a deep appreciation for the natural world, and contributed specimens to museum collections while advocating for conservation efforts.

Despite their historical significance, many natural history museums face challenges today. Budget cuts and dwindling resources have led to the neglect of many museum collections and threatened their long-term preservation. Fortunately, advances in technology offer new opportunities for museums to digitize their collections and make them more accessible to researchers and the public. Collectively, these institutions continue to play a vital role in advancing our understanding of the natural world.
