Much the same happens in women: That's why their bones become less dense.

And when most materials warm up, they expand and become less dense, or lighter.

The size is approximately 280 μm long by 5–6 μm wide. The cephalic tip is bluntly rounded. The nerve ring (excretory pore) and the nucleus of the excretory cell are said to be similar to B. malayi. Behind the nerve ring it was found that the cells of the nuclear column over time become less dense.

Numerous prominently lipped glands are present on the underside of the lid, particularly near the base of the midrib, where they are 0.3 to 0.7 mm wide. Glands become less dense and smaller (around 0.15 mm wide) towards the margins. An unbranched spur measuring 2 to 4 mm is inserted near the base of the lid. Upper pitchers arise from uncurled tendrils.

By changing the viscosity of the endolymph to become less dense when alcohol enters the system, the hair cells can move more easily within the ear, which sends the signal to the brain and results in exaggerated and overcompensated movements of body. This can also result in vertigo, or "the spins.", Why does my head spin when I'm drunk? Rachel Nuwer, 8 Feb 2011, Scienceline.

As the water vapor condenses into liquid, latent heat is released, which warms the air, causing it to become less dense than the surrounding, drier air. The air tends to rise in an updraft through the process of convection (hence the term convective precipitation). This process creates a low-pressure zone within and beneath the forming thunderstorm. In a typical thunderstorm, approximately 500 million kilograms of water vapor are lifted into the Earth's atmosphere.

Osteopetrosis, literally "stone bone", also known as marble bone disease or Albers-Schönberg disease, is an extremely rare inherited disorder whereby the bones harden, becoming denser, in contrast to more prevalent conditions like osteoporosis, in which the bones become less dense and more brittle, or osteomalacia, in which the bones soften. Osteopetrosis can cause bones to dissolve and break. It is one of the hereditary causes of osteosclerosis. It is considered to be the prototype of osteosclerosing dysplasias.

The temporary implants take most of the burden off of the fracture, causing the bone to become less dense. This can lead to the re- fracturing of the bone after the implant is removed. The implants can also cause stress concentrations as a result of the material difference between the bone and the plate. With the permanent prostheses, a putty like substance is injected into the implant site to keep the body, mainly the immune system, from fighting off the implant.

Alchemilla diademata has an erect high stem. The stem is highly pubescent at the base, the trichomes become less dense at the tips. The leaves are basal and measure wide and wide; they resemble lobed kidneys with an oval with an inward curve on one side The leaves are incised to the third into 7 to 9 lobes, each of them fringed by 6 to 7 teeth on each side of the lobes. The teeth end with bristles and are slightly connivent.

This means that equatorial regions of a star will have a greater centrifugal force when compared to the pole. The centrifugal force pushes mass away from the axis of rotation, and results in less overall pressure on the gas in the equatorial regions of the star. This will cause the gas in this region to become less dense, and cooler. Von Zeipel's theorem states that the radiation from a star is proportional to the local effective gravity, that is to the gravity reduced by any centrifugal force at that location on the star's surface.

The bean decreases in weight as moisture is lost and increases in volume, causing it to become less dense. The density of the bean also influences the strength of the coffee and requirements for packaging. The actual roasting begins when the temperature inside the bean reaches approximately , though different varieties of seeds differ in moisture and density and therefore roast at different rates. During roasting, caramelization occurs as intense heat breaks down starches, changing them to simple sugars that begin to brown, which alters the color of the bean.

This creates circulating flow: convection. As it relies on gravity, there is no convection in free-fall (inertial) environments, such as that of the orbiting International Space Station. Natural convection can occur when there are hot and cold regions of either air or water, because both water and air become less dense as they are heated. But, for example, in the world's oceans it also occurs due to salt water being heavier than fresh water, so a layer of salt water on top of a layer of fresher water will also cause convection.

It is projected that the ocean will experience severe acidification under RCP 8.5, high CO2 emission scenario, and less intense acidification under RCP 2.6, low CO2 emission scenario. Ocean acidification will impact marine organisms (corals, mussels, oysters) in producing their limestone skeleton or shell. When CO2 dissolves in seawater, it increases protons (H+ ions) but reduces certain molecules, such as carbonate ions in which many oysters needed to produce their limestone skeleton or shell. The shell and the skeleton of these species may become less dense or strong.

Breast and connective tissues are radiographically denser (they produce a brighter white on an X-ray) than adipose tissue on a mammogram, so a woman with more breast tissue and/or more connective tissue is said to have greater breast density. Breast density is assessed by mammography and expressed as a percentage of the mammogram occupied by radiologically dense tissue (percent mammographic density or PMD). About half of middle-aged women have dense breasts, and breasts generally become less dense as they age. Higher breast density is an independent risk factor for breast cancer.

In the critical depth of 1.2-1.3 km, the density of rock salt and surrounding rocks are roughly the same. At greater burial depth, density inverse and rock salt become less dense than the overburden rocks, which leads to positive buoyancy of the rock salt and causes the rise of salt. As temperature increases with depth, salt is heated and expands, this also leads to increase in buoyancy of rock salt. However, when the overburden is thick enough, the salt will not be able to pierce the overburden by buoyancy.

This heated, buoyant and less-viscous portion of the upper layer would become less dense due to thermal expansion and rise towards the surface as a Rayleigh- Taylor instability. When the mantle plume reaches the base of the lithosphere, the plume heats it and produces melt. This magma then makes its way to the surface, where it is erupted as lava. Arguments for the validity of the hotspot theory generally centre on the steady age progression of Anahim volcanoes and nearby features: a similar eastward-younging spatiotemporal trend exists for the Yellowstone hotspot track to the southeast.

Stress shielding refers to the reduction in bone density (osteopenia) as a result of removal of typical stress from the bone by an implant (for instance, the femoral component of a hip prosthesis). This is because by Wolff's law, bone in a healthy person or animal will remodel in response to the loads it is placed under. Therefore, if the loading on a bone decreases, the bone will become less dense and weaker because there is no stimulus for continued remodeling that is required to maintain bone mass. The design of porous implant is one typical method to alleviate the problem.

In pressurized water reactors the coolant water is used as a moderator by letting the neutrons undergo multiple collisions with light hydrogen atoms in the water, losing speed in the process. This moderating of neutrons will happen more often when the water is denser, because more collisions will occur. The use of water as a moderator is an important safety feature of PWRs, as any increase in temperature causes the water to expand and become less dense; thereby reducing the extent to which neutrons are slowed down and hence reducing the reactivity in the reactor. Therefore, if reactivity increases beyond normal, the reduced moderation of neutrons will cause the chain reaction to slow down, producing less heat.

According to estimation of this theory, space and time emerged together ago and the energy and matter initially present have become less dense as the universe expanded. After an initial accelerated expansion called the inflationary epoch at around 10−32 seconds, and the separation of the four known fundamental forces, the universe gradually cooled and continued to expand, allowing the first subatomic particles and simple atoms to form. Dark matter gradually gathered, forming a foam-like structure of filaments and voids under the influence of gravity. Giant clouds of hydrogen and helium were gradually drawn to the places where dark matter was most dense, forming the first galaxies, stars, and everything else seen today.

Wolff's law, developed by the German anatomist and surgeon Julius Wolff (1836–1902) in the 19th century, states that bone in a healthy person or animal will adapt to the loads under which it is placed. If loading on a particular bone increases, the bone will remodel itself over time to become stronger to resist that sort of loading. The internal architecture of the trabeculae undergoes adaptive changes, followed by secondary changes to the external cortical portion of the bone,Stedman's Medical Dictionary (Wayback Machine PDF) perhaps becoming thicker as a result. The inverse is true as well: if the loading on a bone decreases, the bone will become less dense and weaker due to the lack of the stimulus required for continued remodeling.

This heated, buoyant, and less-viscous portion of the upper layer would become less dense due to thermal expansion, and rise towards the surface as a Rayleigh-Taylor instability. When the mantle plume reaches the base of the lithosphere, the plume heats it and produces melt. This magma then makes its way to the surface, where it is erupted as lava. Arguments for the validity of the hotspot theory generally center on the steady age progression of the Hawaiian islands and nearby features: a similar bend in the trail of the Macdonald hotspot, the Austral–Marshall Islands seamount chain, located just south; other Pacific hotspots following the same age-progressed trend from southeast to northwest in fixed relative positions; and seismologic studies of Hawaii which show increased temperatures at the core–mantle boundary, evidencing a mantle plume.
