Milk is a white liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infants before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother’s antibodies to the baby and can reduce the risk of many diseases in the baby. The precise components of raw milk vary by species and by a number of other factors, but it contains significant amounts of saturated fat, protein and calcium as well as vitamin C.
In almost all mammals, milk is fed to infants through breastfeeding, either directly or by expressing the milk to be stored and consumed later. Some cultures, historically or currently, continue to use breast milk to feed their children until they are seven years old. Human infants sometimes are fed fresh goat milk, but there are known risks in this practice, such as developing a host of allergic reactions.

Stephen LaBerge (born 1947) is a psychophysiologist and a leader in the scientific study of lucid dreaming. In 1967 he received his Bachelor’s Degree in mathematics. He received his Ph.D. in Psychophysiology at Stanford University in 1980.
He developed a technique to enable himself and other researchers to enter a lucid dream state at will, MILD (mnemonic induction of lucid dreams), which was necessary for many forms of dream experimentation. In 1987, he founded The Lucidity Institute, an organization that promotes research into lucid dreaming, as well as running courses for the general public on how to achieve a lucid dream.

Freckles are clusters of concentrated melanin (an organic pigment ubiquitous in nature) which are most often visible on people with a fair complexion. A freckle is also called an ‘ephelis.’ In contrast to lentigines (liver spots) and moles, freckles do not have an increased number of melanin producing cells (melanocytes). Freckles can be found on anyone no matter their genetic background; however, having freckles is genetic and is related to the presence of a dominant gene.
The formation of freckles is triggered by exposure to sunlight: UV-B radiation activates melanocytes to increase melanin production, which can cause freckles to become darker. Freckles are predominantly found on the face, although they may appear on any skin exposed to the sun, such as the shoulders. They are rare on infants, and more commonly found on children before puberty. Upon exposure to the sun, freckles will reappear if they have been altered with creams or lasers and not protected from the sun, but do fade with age in some cases. They can also be treated with citric acid.

Knismesis [niz-muh-sis] and gargalesis [gar-gal-uh-sis] are the scientific terms, coined in 1897 by psychologists G. Stanley Hall and Arthur Allin, used to describe the two types of tickling. Knismesis refers to light, feather-like type of tickling, which generally does not induce laughter and is often accompanied by an itching sensation. Knismesis can also be triggered by crawling insects or parasites, prompting scratching or rubbing at the ticklish spot, thereby removing the pest. It is possible that this function explains why knismesis produces a similar response in many different kinds of animals. In a notable example, it is possible to tickle the area just under the snout of a great white shark, putting it into a near-hypnotic trance.
Gargalesis refers to harder, laughter-inducing tickling, and involves the repeated application of high pressure to sensitive areas. This ‘heavy tickle’ is often associated with play and laughter. The gargalesis type of tickle works on humans and primates, and possibly on other species. Because the nerves involved in transmitting ‘light’ touch and itch differ from those nerves that transmit ‘heavy’ touch, pressure and vibration, it is possible that the difference in sensations produced by the two types of tickle are due to the relative proportion of itch sensation versus touch sensation. While it is possible to trigger a knismesis response in oneself, it is usually impossible to produce gargalesthesia, the gargalesis tickle response, in oneself.

God Helmet refers to an experimental apparatus used in neuroscience, primarily in the field of neurotheology (the study of correlations of neural phenomena with subjective experiences of spirituality). Originally called the ‘Koren helmet’ after its inventor Stanley Koren, it was conceived to study creativity and the effects of subtle stimulation of the temporal lobes. Reports by participants of a ‘sensed presence’ brought public attention to the device. The apparatus, placed on the head of an experimental subject, generates weak fluctuating (i.e. ‘complex’) magnetic fields. These fields are approximately as strong as those generated by a land line telephone handset or an ordinary hair dryer, but far weaker than that of an ordinary fridge magnet.
Michael Persinger, a Canadian neuroscientist, has published extensively about the effects on the human brain of the ‘complex’ magnetic fields generated by the God helmet and similar devices. Many subjects have reported ‘mystical experiences and altered states’ while wearing the God Helmet.

Near-death studies is a school of psychology and psychiatry that studies the phenomenology and after-effects of a Near-death experience (NDE). The NDEs are reported by people who have come close to dying in a medical or non-medical setting.
Some researchers try to study the postulated role of physiological, psychological and transcendental factors associated with the NDE. These factors come together to form an overall pattern when numerous NDE reports are considered together. It is this pattern that is one of the main objects of interest for Near-Death studies.

Energy shots are a specialized kind of energy drink. Sold in 59ml (2 fluid oz.) bottles, energy shots normally contain the same amount of caffeine, vitamins or other functional ingredients as their larger siblings, and therefore they may be considered concentrated forms of energy drinks. Also similar to energy drinks, energy shots contain caffeine, vitamins, and herbs such as guarana, ginseng or ginkgo biloba, taurine, maltodextrin, inositol, carnitine, creatine or glucuronolactone. Most energy shots contain sugar; however, many brands also offer artificially-sweetened ‘diet’ versions. The central ingredient in most energy shots is caffeine, the same stimulant found in coffee or tea. The average 50ml energy shot has about 80 mg of caffeine. This is approximately equivalent to a cup of coffee.
The idea of energy shots started decades ago in the Far East, notably in Japan, where small ‘tonics’ became very popular among consumers; they were highly concentrated and without carbonation. In 2004 the first suppliers, like 5-Hour Energy, Nitro2Go, and ZipFizz, took up the idea and launched these energy shots in the US, opening up a sub-segment in the energy drink market. Although originally marketed in the US, energy shots are becoming more popular in other parts of the world, like Europe, Asia and Australia.

Hologram therapy is the pseudoscientific practice of adorning oneself with hologram jewelry for enhancement of athletic performance. Merchants claim it to be a method in alternative holistic medicine that can improve general physical fitness and athletic prowess. It centers around wearing plastic holograms purported to resonate with frequencies that react positively with the putative energy field of the human body.
Promoters borrow from concepts in crystal healing, vibrational medicine, energy medicine, and physics, but provide a sparse and disjointed scientific explanation. The holograms are printed on stickers, plastic wristbands, and pendants. Promoters rely heavily on the ritualistic superstition that often characterizes athletes.

A form constant is one of several geometric patterns which are recurringly observed during hallucinations and altered states of consciousness. In 1926, psychologist Heinrich Klüver systematically studied the effects of mescaline on the subjective experiences of its users. In addition to producing hallucinations characterized by bright, ‘highly saturated’ colors and vivid imagery, Klüver noticed that mescaline produced recurring geometric patterns in different users. He called these patterns ‘form constants’ and categorized four types: lattices (including honeycombs, checkerboards, and triangles), cobwebs, tunnels, and spirals.
Klüver’s form constants have appeared in other drug-induced and naturally-occurring hallucinations, suggesting a similar physiological process underlying hallucinations with different triggers. Klüver’s form constants also appear in near-death experiences and sensory experiences of those with synesthesia. Other triggers include psychological stress, threshold consciousness(hypnagogia), insulin hypoglycemia, the delirium of fever, epilepsy, psychotic episodes, advanced syphilis, sensory deprivation, photostimulation, electrical stimulation, crystal gazing, migraine headaches, dizziness and a variety of drug-induced intoxications. These shapes may appear on their own or with eyes shut in the form of phosphenes, especially when exerting pressure against the closed eyelid.

Purple drank is a slang term for a recreational drug popular in the hip hop community in the southern United States, originating in Houston, Texas. Its main ingredient is prescription-strength cough syrup containing codeine and promethazine. Cough syrup is typically mixed with ingredients such as Sprite soft drink or Mountain Dew and pieces of Jolly Rancher candy. The purplish hue of purple drank comes from dyes in the cough syrup. Producer DJ Screw popularized the concoction in the 1990s, which is widely attributed as a source of inspiration for the ‘chopped and screwed’ style of hip hop music. However, musician Big Hawk claims it was consumed as early as the 1960s and 1970s.
DJ Screw died of a codeine-promethazine-alcohol overdose in 2000. Purple drank is confirmed or suspected to have caused the deaths of several prominent users. Respiratory depression is a potentially serious or fatal adverse drug reaction associated with the use of codeine, but mainly the danger lies in the much more potent and CNS-depressing phenothiazine-related antihistamine promethazine.

A hug machine, or squeeze box, is a deep-pressure device designed to calm hypersensitive persons, usually individuals with autism spectrum disorders. The therapeutic, stress-relieving device was invented by professor of animal science Temple Grandin in 1965.
Autism and autism-spectrum disorders have profound effects upon both social interactions and sensitivity to sensory stimulation in persons with such conditions, often making it uncomfortable or impractical for them to turn to other human beings for comfort. Grandin solved this by designing the hug machine so both she and others could turn to it for sensory relief, whenever needed or simply desired.

Bionic contact lenses are being developed to provide a virtual display that could have a variety of uses from assisting the visually impaired to the video game industry. The lenses require organic materials that are biologically safe and also use inorganic material for the electronic circuits. The electronic circuits are built from a layer of metal a few nanometres thick. The light-emitting diodes are one third of a millimetre across. A grey powder is sprinkled onto the lens. Then a technique called microfabrication or ‘self-assembly’ is used to shape each tiny component. Capillary forces pull the pieces into their final position.
Wireless communication, radio frequency power transmission and solar cells are expected in future developments. The prototype does not light up or display information; however, it is proof that it is possible to create a biologically safe electronic lens that does not obstruct a person’s view. Engineers have tested the finished lenses on rabbits.
