If an instance’s dictionary has an entry with the same name as a data descriptor, the data descriptor takes precedence. If an instance’s dictionary has an entry with the same name as a non-data descriptor, the dictionary entry takes precedence.

researchers report that young people aged 20-30 are able to accurately guess when a scent comes from an elderly individual aged 75-95

in the order Hyracoidea. they look more like small rodents though.

domestic cats make subtle use of one of their most characteristic vocalisations – purring – to solicit food from their human hosts, apparently exploiting sensory biases that humans have for providing care. When humans were played purrs recorded while cats were actively seeking food at equal amplitude to purrs recorded in non-solicitation contexts, even individuals with no experience of owning cats judged the “solicitation” purrs to be more urgent and less pleasant. Embedded within the naturally low-pitched purr, we found a high frequency voiced component, reminiscent of a cry or meow, that was crucial in determining urgency and pleasantness ratings. Moreover, when we re-synthesised solicitation purrs to remove only the voiced component, paired presentations revealed that these purrs were perceived as being significantly less urgent. We discuss how the structure of solicitation purrs may be exploiting an inherent mammalian sensitivity to acoustic cues relevant in the context of nurturing offspring.

Addison’s disease is a disorder that occurs when the adrenal glands do not produce enough of their hormones.

physicists predicted that electrons in a one-dimensional chain of atoms could be split into three quasiparticles: a %u2018holon%u2019 carrying the electron%u2019s charge, a %u2018spinon%u2019 carrying its spin (an intrinsic quantum property related to magnetism) and an %u2018orbiton%u2019 carrying its orbital location

Evidence of a person’s habit or an organization’s routine practice may be admitted to prove that on a particular occasion the person or organization acted in accordance with the habit or routine practice. The court may admit this evidence regardless of whether it is corroborated or whether there was an eyewitness.

One out of three builders say they lost signed sales contracts during the last half of 2011 because appraisals on their homes were less than the sales price the buyer agreed to, according to the latest data from the National Association of Home Builders.

since Cat’s Cradle, scientists have discovered some real-world example of crystals that seed the environment, converting other forms (polymorphs) of the crystal into their own.

the exudate from the castor sacs of the mature North American Beaver Castor canadensis and the European Beaver Castor fiber. Within the zoological realm, castoreum is the yellowish secretion of the castor sac in combination with the beaver’s urine, used during scent marking of territory

Used as “natural flavor” vanilla substitute in various foods and beverages.

rigid suit filled with water to allow pilots to withstand up to 10Gs.

A person immersed in liquid of the same density as tissue has acceleration forces distributed around the body, rather than applied at a single point such as a seat or harness straps.

double refraction, is the decomposition of a ray of light into two rays when it passes through anisotropic materials, such as crystals of calcite or boron nitride.

In photography, acutance is the edge contrast of an image. Acutance is related to the amplitude of the derivative of brightness with respect to space. Due to the nature of the human visual system, an image with higher acutance appears sharper even though an increase in acutance does not increase real resolution.

The sampling rate of such a system is constrained to relate simply to the field rate and field structure of the television standard used, so that an integer number of samples can be stored on each usable TV line in the field. Such a recording can be made on a monochrome recorder, and these recording are made in two standards, 525 lines at 60 Hz and 625 lines at 50 Hz.

In engineering a dog is a tool that prevents movement or imparts movement by offering physical obstruction or engagement of some kind. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison - the primary example of this being a flexible drive to mate two shafts in order to transmit torque.
