Arenaviridae
Arenaviridae is a family of viruses that primarily infect mammals, including rodents. These viruses have a double-stranded RNA genome and are known for causing hemorrhagic fever in humans. They are typically transmitted to humans through contact with infected rodent urine, feces, or saliva, or by inhaling contaminated dust. Some notable members of this family include Lassa virus and Machupo virus, which can lead to severe illness and have high mortality rates if not treated promptly.
Arenavirus
Arenavirus is a type of virus that belongs to the family Arenaviridae. These viruses are primarily found in rodents and can cause severe human illnesses, such as hemorrhagic fever. Transmission to humans usually occurs through contact with infected rodent urine, feces, or saliva, or through inhalation of contaminated dust. Arenaviruses have a biphasic genome consisting of two single-stranded RNA segments, and they are known for their ability to replicate in both immune and non-immune cells. Some notable examples of arenaviruses include Lassa fever virus and Machupo virus, which cause significant public health concerns in certain regions.
Arene
"Arene" is a term used in chemistry, specifically in organic chemistry, to refer to a type of aromatic hydrocarbon. It denotes a flat, cyclic structure consisting of six carbon atoms bonded together in a hexagonal planar ring, with alternating single and double bonds. The most well-known arene is benzene (C6H6), but the term can also encompass other similar compounds with this ring structure, such as naphthalene or anthracene. Arenes often exhibit unique chemical properties due to their aromaticity, which makes them important in various industrial applications and chemical reactions.
Arenes
Arene is a term used to describe a type of unsaturated ring-shaped molecule, specifically a hydrocarbon containing a 6-carbon ring with alternating double bonds. Examples of arenes include benzene, toluene, and xylene. Arene is derived from the Greek word "areno", meaning "fiery" or "incandescent", as these compounds were often obtained from coal tar, a byproduct of coal gasification, which was used for lighting and was known to ignite easily. The term "arene" is often used to distinguish these compounds from saturated hydrocarbons, which do not have double bonds within the ring structure.
Arenicolite
Arenicolite is a fossilized imprint or casts of burrows made by marine animals, typically worms, in sedimentary rocks. It provides evidence of ancient underwater ecosystems and the activity of organisms that lived in the seafloor.
Arenicolous
Arenicolous refers to organisms that live in or on sand, particularly sandy beaches or dunes. It comes from the Latin word "arena," meaning sand, and the suffix "-colous," which denotes a habitat or dwelling place. Therefore, arenicolous species are those adapted to living in sandy environments.
Arenilitic
Arenilitic refers to sedimentary rocks or sediments primarily composed of sand-sized grains of minerals, especially quartz, feldspar, and lithics. It is often used to describe sandstone formations.
Arenite
Arenite is a type of sedimentary rock primarily composed of sand-sized grains of minerals, rocks, and organic matter. It is usually formed from the cementation and compaction of sand-sized particles that have been deposited by water, wind, or ice. Arenites are often grainy and have a sandy texture, and they can vary in color depending on the composition of the grains. They are a common component of continental and marine sedimentary environments.
Arenose
The word "arenose" is an adjective used to describe something that is sandy or consisting of sand. It often refers to soils or sediments with a high content of sand particles.
Arenulous
The word "arenulous" is an adjective that means consisting of or containing sand, sandy, or having the characteristics of sand. It often refers to soil or other substances that have a significant amount of sand mixed in.
Areocentric
Aerocentric refers to something centered around or related to the Earth, particularly in the context of astronomy or space exploration. It contrasts with geocentric, which means Earth-centered. In the past, the term was used to describe the now-obsolete idea that the Earth was the center of the solar system. Today, it is more commonly used to discuss Earth-oriented observations or systems in space.
Areola
The areola is the circular area of pigmented skin surrounding the nipple on the breast of humans, typically females. It varies in color and size and plays a role in sexual attraction as well as providing a protective function for the nipple.
Areolae

In a broader sense, "areolar" can also refer to anything that is characterized by a circular or ring-like formation. For example, an areolar pattern on a leaf is a pattern of veins that radiate from the center of the leaf like the spokes of a wheel. In embroidery and other textiles, an areolar stitch is a type of stitch that is used to create a circular or ring-like pattern.
