Data Ownership in Healthcare
This section briefly discusses this issue of data ownership in the light of recent privacy laws. These laws have a very large impact on the topic of data sharing. It shows that these privacy laws provide rights to the patient, but they do not necessarily make clear who is the owner of the data. They only provide a legal framework for the handling of the data.

Dilophosauridae
Dilophosauridae is a family of medium to large sized theropod dinosaurs. The name Dilophosauridae is derived from Greek, with “di-” meaning “two,” “lophos” meaning “crest,” “sauros” meaning “lizard,” and “-idae” meaning “family”. While the name suggests that all dilophosaurids have two crests, this is not applicable to all dilophosaurids. The Dilophosauridae is anchored by its type genus, Dilophosaurus, and therefore the name comes from the distinctive two crests of the genus.

Fungal Pigments
Fungi can produce a large diversity of pigments. Based on their chemical structures, fungal pigments are broadly grouped into carotenoids, melanin, polyketides, and azaphilones etc. These pigments differ in many aspects, including colouration and physical and chemical properties such as molecular size, structure, hydrophobicity, reactivity and biological roles. While the same fungus may be able to produce different pigments, structurally similar pigments can be produced by fungi in evolutionarily divergent lineages. Some of these pigments play positive roles in human welfare, including vitamin precursors, antibiotics, immunomodulators and colourants. However, when present in human fungal pathogens, these pigments can also enhance the virulence and pathogenicity of these organisms. While significant progresses have been made for understanding fungal pigments, much remains unknown, including the structure-function relationships and the genes and metabolic pathways involved in their synthesis for the majority of fungal pigments.

Impact of Self-Driving Cars
The impact of self-driving cars is anticipated to be wide-ranging on many areas of daily life. Self-driving cars have been the subject of significant research on their environmental, practical, and lifesyle consequences. One significant predicted impact of self-driving cars is a substantial reduction in traffic collisions and resulting severe injuries or deaths. United States government estimates suggest 94% of traffic collisions are caused by human error, with a 2020 study estimating that making 90% of cars on US roads self-driving would save 25,000 lives per year. While this has significant benefits, other health downsides of self-driving cars are predicted; self-driving cars are suggested to worsen air pollution, noise pollution, and sedentary lifestyles, and may contribute to shortages of donor organs. Self-driving cars are anticipated to increase productivity and housing affordability, as well as reclaim land used for parking. However, they are also predicted to cause greater energy use, traffic congestion and sprawl. The impact of self-driving cars on absolute levels of individual car use is not yet clear, with commentators alternatively predicting increases and decreases. Self-driving cars are one of several potential autonomous vehicles, and other forms of self-driving vehicles, such as self-driving buses, may decrease car use and congestion in ways self-driving cars are unlikely to. The effect of self-driving cars on various employment fields is predicted to be wide-ranging. Impacts are anticipated on the healthcare, insurance, travel, and logistics fields. Auto insurance costs are expected to decrease, and the burden of cars on the healthcare system to reduce. Self-driving cars are predicted to have substantial and wide-ranging effects on transportation industries, with significant job losses in these fields.

Talkboy
Talkboy is a line of handheld voice recorder and sound novelty toys manufactured by Tiger Electronics (now owned by Hasbro) in the 1990s. The Talkboy was originally conceived as a cassette recorder and player prop for the 1992 film Home Alone 2: Lost in New York. At the request of director John Hughes and 20th Century Fox, Tiger designed and built the prop, and was given permission by the movie studio to sell a retail version of the toy. Two cassette recorders modeled after the film prop were released in 1992 and 1993, respectively. The original model did not have the variable-speed voice changer of the film version and sold only moderately during the 1992 holiday shopping season. In April 1993, Tiger released the Deluxe model, which added the voice-changing feature. Following the release of Home Alone 2 on home video in July with an insert advertising the Deluxe Talkboy, interest in the toy spiked. Retailers had severely underestimated demand, and as a result the Deluxe Talkboy was one of the most highly sought-after toys during the 1993 holiday shopping season, selling out of stores across the United States. A pink version of the cassette recorder called "Deluxe Talkgirl" was released in 1995. The success of the Talkboy cassette recorders spawned a product line of electronic toys. Tiger transitioned to digital recorders for subsequent devices, using solid-state storage and adding sound effects, beginning with "Talkboy/Talkgirl F/X+" pens in 1995, which sold more than a million units in 45 days.

Polyphenolic-Food and Longevity
Aging and, particularly, the onset of age-related diseases are associated with tissue dysfunction and macromolecular damage, some of which can be attributed to accumulation of oxidative damage. Recently, growing interest has emerged on the beneficial effects of plant-based diets for the prevention of chronic diseases including obesity, diabetes, and cardiovascular disease. Several studies collectively suggests that the intake of polyphenols and their major food sources may exert beneficial effects on improving insulin resistance and related diabetes risk factors, such as inflammation and oxidative stress. They are the most abundant antioxidants in the diet, and their intake has been associated with a reduced aging in humans. Polyphenolic intake has been shown to be effective at ameliorating several age-related phenotypes, including oxidative stress, inflammation, impaired proteostasis, and cellular senescence, both in vitro and in vivo.

Tissues to Implant Abutments
This entry is based on the fact that physical or biomechanical phenomena can cause biologic results. Implant-abutment connection structures determine the stability of soft tissue attachment to abutments. The bone responses to the strain that the stress is converted to, not the stress itself. Some implant-abutment materials and connection designs prevent the marginal bone loss by converting the stress to the strain stimulating bone apposition properly. These biomechanical interpretation of soft tissue seal and bone stimulation should be understood for the clinical long-term success of dental implants.

Mercury's Magnetic Field
Mercury's magnetic field is approximately a magnetic dipole (meaning the field has only two magnetic poles) apparently global, on planet Mercury. Data from Mariner 10 led to its discovery in 1974; the spacecraft measured the field's strength as 1.1% that of Earth's magnetic field. The origin of the magnetic field can be explained by dynamo theory. The magnetic field is strong enough near the bow shock to slow the solar wind, which induces a magnetosphere.
