From Quiz Great Science Questions

Answer: Plastic

There are several garbage patches in the world's oceans, but the largest is in the North Pacific. By 2020, it contained 79 thousand metric tons of garbage and sprawled 1.6 million square kilometers (almost the size of Alaska). The vast majority is plastic, especially microplastics which are created when plastics degrade. The floating plastic creates ecological hazards, especially to birds and marine mammals. In recent years, several non-governmental organizations have started efforts to clean up the garbage patch, but it is a monumental task, The National Oceanic and Atmospheric Administration estimated it would take 67 boats one full year to clean up just one percent of the Pacific Garbage Patch,

Answer: Spectroscopy

There are several types of spectroscopy, most of which involve the use of electromagnetic radiation. The most popular types are UV-Vis spectroscopy, in which the radiation is either in the visible or ultraviolet range, and IR spectroscopy, in which the radiation is in the infrared spectrum. In addition to these common forms of spectroscopy, many other variants, such as acoustic spectroscopy, are also used in scientific research.

From Quiz FunTrivia Sci / Tech Mix: Vol 16

Answer: left and right brain specialization

One must be careful when discussing brain lateralization, as the evidence concerning this field is inconclusive. There is still much research to do, but scientists have generally discovered that the left hemisphere and right hemisphere take on different tasks linguistically. The "left brain" generally handles language functions such as grammar and vocabulary, while the "right brain" handles the aspects of language such as intonation and stress; however, this is not the case for everyone. Sometimes opposite hemispheres can even take on the functions of the other if a person suffers brain damage.

Answer: regurgitate

Regurgitation is the (normally) involuntary ejection of the contents of the stomach through the mouth. ["Regurgitate" is also a rock-and-roll band in Sweden, but that is quite another matter.] This medical term entered English from the Medieval Latin "regurgitatus" which is the past participle of "regurgitare" meaning to surge or to flood. Exsanguinate is to bleed. Expectorate is to spit. Micturate it to pass urine.

Answer: Universal Serial Bus

The Universal Serial Bus was designed and established around 1995 or 1996 by a group of seven 'tech' companies in order to regiment a plethora of external devices that get connected to a host computer. That's about all the information I can give you on the topic, except to say I don't go anywhere without my USB mass-storage device, or flash drive, or as us Luddites like to call it: memory stick.

Answer: hearing

A cochlear implant is an electronic device which converts sound waves into electrical signals which are transmitted directed to the auditory nerve. The hearing is different from that afforded by the more common acoustic hearing process but is a remarkable adaptation, especially for the profoundly deaf. Earliest models were invented in 1957; later versions were invented in 1961, 1964 and 1977. Some members of the Deaf Community oppose the use of cochlear implants because they regard them as a threat to their culture.

Answer: Saltpetre

Saltpetre helped the preserving salt to penetrate the meat more evenly and also preserved its pink colour. Although it is a preservative and has pharmaceutical applications, potassium nitrate is on the Hazardous Substance List as it can be seriously harmful if directly ingested or inhaled - not to mention its use in gunpowder and other explosives, besides fertilisers. The name saltpetre can apply to both potassium and sodium nitrate.

Question by player tritran5555

From Quiz The Science of Cows

Answer: Cows have distinctive individual voices

Green spent five months listening to a herd of Holstein-Freisian heifers and analyzing their acoustical patterns. She determined that individual cows have individual voices that enable them to communicate emotions such as excitement, arousal or distress. According to Greene, these vocal cues remain consistent in both positive and negative situations. Green's research was published in the December 2019 issue of "Scientific Reports." It could enable farmers to better understand the emotional state of their herds. Green was assisted in her research by bio-acoustic specialists Professor David Reby and Dr Livio Favaro. Remarkably, scientific research has shown that cow saliva does indeed have healing properties. Cows and humans share about 80 percent of the same genes.

From Quiz Color Me Purple Part 9 - The Science of Purple

Answer: hematite and manganese

Pigments of both hematite and manganese were used to create the colour purple, by Neolithic and New Stone Age artists. These minerals were finely ground before being mixed with fat, and finally moulded into sticks to be used for painting. Manganese was also later used by the Romans to colour glass purple. Cadmium and chromium pigments were mainly used to provide the colour yellow, although cadmium was also used to create both red and orange. Mercury pigments were mainly used to create the bright red colour vermilion, whilst iron oxide provided various shades of red. (Question by moonraker2)

From Quiz In the Year 2525

Answer: Exoskeleton

In general, these suits enable the wearer to lift and move in ways that seem super-human. Very little modification needs to be done for use with paralyzed legs, and semi-automated prototypes for paralyzed arms are currently being developed. The system works by transferring weight from the body to the exoskeleton itself, allowing people to carry more and work longer with less strain. For paralyzed people, the limbs of the exoskeleton are strong enough that a person can smoothly stand and walk around with very minimal effort.

From Quiz The Jury's Still Out on Science

Answer: Diederik Stapel

Stapel's 130 articles and 24 book chapters were investigated by three committees. Their joint final report found that Stapel's high academic status and charismatic personality permitted him to get away with fraudulent behaviour. All agreed that Stapel had not only damaged the careers of graduates but also the pursuit of science, particularly social psychology. In his apology, Stapel made some salient points: "I did not withstand the pressure to score, to publish, the pressure to get better in time. I wanted too much, too fast. In a system where there are few checks and balances, where people work alone, I took the wrong turn."

From Quiz If cats have kittens...

Answer: In the waters that flow over the coral reefs

Corals eject clouds of eggs and sperm which drift together in the tides and currents. The phases of the moon seem to dictate that all the corals eject them at the same time, causing a phenomenon that divers like to watch.

Melanism gets its name from melanin, which is responsible for giving skin its color. People with a high concentration of melanin are shown to be less likely to develop skin cancer.

From Quiz The Space Between

Answer: Boy scouts

Boy scouts, along with astronauts, are taught to be responsible, follow through on tasks, display initiative, and pay strict attention to details. Indeed, of the 312 scientists and pilots selected since 1959 to take part in some way in the space program, 207 of these were involved in some level of the scouts as they were growing up. Twenty-seven of these were women who had been girl scouts in their youth. Of the 24 men who travelled to the moon, 20 of these were members of the scouts as boys, and 11 of the 12 men who actually set foot on the moon were also members of this very worthy boyhood organisation.

From Quiz Back to Square One

Answer: Cells & Cell

The term 'cell' came from the Latin word 'cella', which means 'small rooms'. When Hooke saw the cells of the cork he was examining through his microscope, he likened them to monk's cells. Robert Hooke did not only delve into microsopy; he was a true Renaissance man. He studied and published in many fields, including mechanics, gravitation, paleontology, astronomy, and human memory.

From Quiz Summing Up Science With Headlines

Answer: DNA Structure Solved

Two British-based groups are often credited with the discovery of the structure of DNA - the famous double helix (or twisted ladder). One group was based in Cambridge and included the experienced Francis Crick and the young and self-confident James Watson. The second group was based at King's College, London, and was led by Maurice Wilkins. Wilkins was later joined at King's by Rosalind Franklin, a sharp but acerbic scientist who specialised in X-ray crystallography. This rather arcane field seems daunting, but was the key to the discovery of the structure of DNA and remains the leading method for structural analysis of proteins (a rapidly developing area of study). At the same time, Linus Pauling was working on the structure of DNA in America. Pauling was a giant in the field of structural biology and when he announced he had discovered the structure of DNA, the British groups felt resigned. However, it soon became clear that Pauling's triple helix model did not fit with the excellent X-ray images of Rosalind Franklin. It is unjust that, despite it being her images that led to the development of the double helix model, Rosalind Franklin is often written out of the history books. Some put this down to sexism (which may have some truth), but it may also be due to her passing away before the Nobel Prize was awarded to Crick, Watson, and Wilkins.
