Micro-CT provides high resolution 3D imaging of the interior structure of materials and biological samples without having to cut the samples.

The aortic valve of the human heart typically contains three leaflets or cusps, hence called the tri-leaflet valve. When the valve opens it allows blood to exit the left ventricle into the aorta. Once closed, blood movement stops. In the case of a dysfunction, the tri-leaflet valve is repaired or replaced by a surgery. The technology described in this article provides a promising approach to create artificial implants for these surgeries.

Hydrogels are 3D networks of hydrophilic polymers that can hold a lot of water while still maintaining structure.

Negative Nb anomalies are characteristic of subducted material. Subducted material includes continental-sources sediments from the ocean floor that gets subducted into the mantle. The trace element patterns look more like the crust than the mantle, which means that the fluid inclusions' trace element record is not recording any mantle processes.

A kind of intrusive, igneous rock that is formed deep inside the Earth’s interior. Kimberlite tends to move upwards via the upper mantle and lower and upper crusts, ultimately reaching the surface of the Earth. When the rocks move up, they carry diamonds inside them, thereby becoming an important source of diamonds.

A slab is a part of the tectonic plate which undergoes subduction. Subduction is a geological phenomenon occurring at the junction between two tectonic plates. This involves pushing one plate below the other, so much so that the sinking plate (usually the denser one) protrudes into the Earth’s mantle.

The mid-ocean ridge is one of the largest chain of volcanic mountains on Earth, with 90% of the mountains submerged underneath the ocean. A type of basaltic rock originating from volcanic eruptions in this region is known as mid-ocean ridge basalt.

Mid-ocean ridges occur where two tectonic plates pull apart and the mantle below wells up and then rapidly cools due to the interaction with the ocean's cold water. This is what makes up oceanic crust.

This occurs when magma inside the Earth's mantle gets polluted by small amounts of crustal rocks—that is, rocks from Earth's crust. Shallower crustal rocks are more felsic, which means they contain more feldspar and quartz.

Simply put, resonant frequency is the natural frequency at which it is easiest to get an object to vibrate. Most objects have several resonance frequencies, such as stringed musical instruments that vibrate at their resonance frequencies when plucked or struck, and their vibrations against the surrounding air produce sound. This type of resonance is found when an object is in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.

wikipedia

A mass of undifferentiated cells that has the ability to develop into an organ or body part, such as limbs.

A pattern of temperatures

A 24-hour cycle, more commonly referred to as a "day".

Commonly called "cold-blooded", this term describes an animal that regulates its body temperature using external energy sources. For example, this is the reason why many reptiles sunbathe.

The search for food in the environment.

The period of time that viviparous animals (those that give live birth and do not lay eggs) will carry a developing embryo. The length of this period will vary depending on species; for example humans have a gestation period of 40 weeks, whereas rabbits only take about a month.

Ecologists often use equations to try to describe animal behavior. A "scaling coefficient" is a number by which a variable is multiplied, which is used here to say that temperature (the variable in this case) will cause a larger change in the behavior of prey (large scaling coefficient) than predators (small scaling coefficient).

Caranx ignobilis, the "Giant trevally" is called out as an animal that has some key similarities and differences in behavior from the blacktip reef sharks at the center of this study.

While both are apex predators from the Phylum Chordata, the trevally is a bony fish (Class Actinopterygii) while the shark is a cartilaginous fish (Class Chondrichthyes)

Ambush predators which hunt using stealth or strategy (ex: house cat) rather than speed or strength (ex: cheetah).

Another term for a "variable" that was considered as part of the study as a factor that could potentially explain the behavior in question.

Also known as autocorrelation, this is a phenomenon that occurs within datasets such as a time series in which the data points are not independent of each other. For example, the temperature recorded one minute is very likely to be similar to the temperature that was recorded for the previous time point because these time points have a relationship to each other, as the temperature will only change as quickly between them as the underlying physics allow. This phenomenon has consequences for some statistical analyses that researchers must correct for to avoid generating spurious results.

Striped surgeonfish

Striated surgeonfish

Whitecheek surgeonfish

An infraclass of the class Actinopterygii, this classification includes most ray-finned fishes found in the world today, with only a few exceptions of ancient fish which branched off earlier in evolutionary history.

A device used to detect sounds underwater.

Describes the movements of smooth muscle in the stomach that contract as part of the digestion process.

Many animals "play dead" in response to a stress or threat, but this trance-like state in sharks is thought to be connected to mating since they typically have few predators to feel threatened by. It typically takes 15 minutes for this effect to wear off and has little or no lasting health consequences for the shark.

The numbers refer to the diameter of the tag, with different sizes being better suited to a range of animal sizes and data types.

How many measurements are made over a period of time. A measurement is said to be continuous if it is being constantly tracked, whereas discrete measurements are taken periodically at a time interval that the scientists have determined is frequent enough to answer their research question.

Located in the Pacific, south of Hawaii: With no permanent residents, this is a United States Minor Outlying Island that is part of the largest marine protected area in the world: the Pacific Remote Islands Marine National Monument.

Behaviors performed to control the temperature of an organism such as basking in the sun or seeking shelter.

An example of turtles basking in the sun to increase their body temperature:

The emptying of the stomach which occurs as food moves on to subsequent stages of digestion and the eventual excretion of wastes.

The temperature conditions within which an organism has the best chance of thriving. This is one of several factors that determine the ecological niche of an organism, which describes how its behavior and habitat choice play a specific role in the context of the larger ecosystem that it is a part of.

The classic "bell curve" that is used to describe a normal distribution of values.

Enzymes perform many important functions in our bodies (such as digestion) and have a temperature at which they can perform optimally. Temperatures that are higher or lower will require more energy to perform the same task. Keeping your body, and the enzymes that it contains, at an optimal temperatures is a way to maximize the efficient use of energy.

Refers to things that happen during the twilight hours (dawn and dusk). This is in contract to "nocturnal" things that happen at night or "diurnal" things that happen during the day. Crepuscular animals such as deer, bears, and housecats tend to be the most active during these time periods.

A measurement that can be used to infer the health status of an organism. This is typically calculated by comparing a measurement like length to another like weight, for which a healthy ratio is known.

The human body-mass-index (BMI) can be considered a measurement of body condition, as this is derived from a person's height and the range of weights that are considered to be healthy for that height.

A fish with a high body condition is likely to be on the plump side with excess energy stored as a buffer for times of low food intake or high energy use, while a fish with low body condition would be skinny for its length and have low energy reserves.

The energy required for an organism to perform an action. This includes constant needs such as the maintenance of cells or voluntary actions like the use of muscles for swimming. Organisms must balance all of these metabolic costs with the intake of energy from food, or they will run an unsustainable deficit in their energy budget.

Describes the resistance of an object (or, in this case, an animal) to changes in temperature, and the speed at which it approaches the temperature of its surroundings. A warm fish with high thermal inertia would maintain its heat relatively well in cold waters, whereas a fish with low thermal inertia would lose its heat quickly in cold water and is more likely to have a body temperature that is similar to its surroundings.

The period that follows the high point in the tidal cycle (high tide) as the ebb current pulls water back towards the ocean.

"Diurnal" refers to things that happen during the daytime. This is the opposite of its antonym "nocturnal", which appears much more often in common speech to refer to animals that are active at night. In this case, "diurnal prey" is used to refer to the daytime activity of fish that the sharks may be feeding on.

An island formed when an extinct mid-ocean volcano surrounded by coral reefs is eroded and subsided beneath sea level, leaving only a coral reef ring visible above the ocean surface. These are found only in tropical and subtropical regions where corals can thrive and continue to build up a reef at a rate that keeps pace with the erosion and subsidence of the underlying volcano.

The three-point bend test provides values for the modulus of elasticity, and flexural stress and strain.

Modulus of elasticity is the ratio of the stress in a body to the corresponding strain.

Flexural stress is the maximum bending stress that can be applied to that material before it breaks.

Flexural Strain is the ratio of stress to strain in flexural deformation, or the tendency for a material to resist bending.
