Geranylfarnesyl pyrophosphate is an intermediate used by organisms in the biosynthesis of sesterterpenoids. [1]
Calreticulin also known as calregulin, CRP55, CaBP3, calsequestrin-like protein, and endoplasmic reticulum resident protein 60 (ERp60) is a protein that in humans is encoded by the CALR gene.
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 million years ago; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are modern feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event approximately 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and the extinct non-avian dinosaurs, which are all dinosaurs other than birds.
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation. Evolution occurs when evolutionary processes such as natural selection and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.
The Jurassic is a geologic period and stratigraphic system that spanned from the end of the Triassic period 201.3 million years ago (Mya) to the beginning of the Cretaceous period, approximately 145 Mya. The Jurassic constitutes the middle period of the Mesozoic era and is named after the Jura Mountains, where limestone strata from the period were first identified.
Astraea is a large asteroid from the asteroid belt. Its surface is highly reflective (bright) and its composition is probably a mixture of nickel–iron with silicates of magnesium and iron. It is an S-type asteroid in the Tholen classification system.
Davida is a large C-type asteroid in the asteroid belt. It was discovered by R. S. Dugan in 1903. It is one of the ten largest and most-massive asteroids (7th). Davida is named after David Peck Todd, an astronomy professor at Amherst College.
Hestia is a large, dark main-belt asteroid. It is also the primary body of the Hestia clump, a group of asteroids with similar orbits.
Klio is a fairly large and very dark main-belt asteroid. It was discovered by R. Luther on August 25, 1865, and named after Clio, the Muse of history in Greek mythology. The name Clio had previously been suggested by the discoverer of 12 Victoria, and that is the name B. A. Gould, editor of the prestigious Astronomical Journal, adopted for that asteroid, because of the controversy over the name Victoria. An occultation by Klio over a dim star was observed on April 2, 1997.
Thisbe, minor planet designation 88 Thisbe, is the 13th largest main-belt asteroids. It was discovered by C. H. F. Peters on June 15, 1866, and named after Thisbe, heroine of a Roman fable. An occultation of a star by Thisbe was observed on October 7, 1981. Results from the occultation indicate a larger than expected diameter of 232 km.
704 Interamnia is a large F-type asteroid. With an estimated mean diameter of 330 kilometres, it is the fifth-largest asteroid after Ceres, Vesta, Pallas, and Hygiea. Its mean distance from the Sun is 3.067 (AU). It was discovered on 2 October 1910 by Vincenzo Cerulli, and named after the Latin name for Teramo, Italy, where Cerulli worked. It is probably the fifth-to-eighth-most-massive asteroid, with a mass estimated to be 1.2% of the mass of the entire asteroid belt. Observations by the Very Large Telescope's SPHERE imager in 2017–2019, combined with occultation results, indicate that the shape of Interamnia may be consistent with hydrostatic equilibrium for a body of its density with a rotational period of 7.6 hours. This suggests that Interamnia may have formed as an equilibrim body, and that impacts changed its rotational period after it fully solidified.
Acoelomorpha is a subphylum of very simple and small soft-bodied animals with planula-like features which live in marine or brackish waters. They usually live between grains of sediment, swimming as plankton, or crawling on other organisms, such as algae and corals. With the exception of two acoel freshwater species, all known Acoelomorphs are marine.
Frédéric Michalak is a former French rugby union footballer. His early career was spent playing for his hometown team, Toulouse, in the Top 14 and in the Heineken Cup. He moved to South Africa to play for the Sharks in the Super 14 after the 2007 Rugby World Cup, but after just one year with the Sharks he moved back to Toulouse. He has also played over 70 tests for France to date, and is the country's leading Test point scorer, achieving that milestone in 2015. Michalak originally played scrum-half but has played mainly at fly-half. He has appeared in advertisements for companies such as Nike and Levi's.
Rose hip seed oil is a pressed seed oil, extracted from the seeds of the wild rose bush Rosa rubiginosa in the southern Andes. Rosehip seed oil can also be extracted from Rosa canina, which grows in many regions of the world including South Africa and Europe. The fruits of the rosehip have been used in folk medicine for a long time. Rosehips have prophylactic and therapeutic actions against the common cold, infectious diseases, gastrointestinal disorders, urinary tract diseases, and inflammatory diseases.
Eupatorium cannabinum, commonly known as hemp-agrimony, or holy rope, is a herbaceous plant of the daisy family. It is a robust perennial native to many areas of Europe. It is cultivated as an ornamental and occasionally found as a garden escape in scattered locations in China, the United States and Canada. It is extremely attractive to butterflies, much like buddleia.
Peto's paradox is that at the species level, the incidence of cancer does not appear to correlate with the number of cells in an organism. For example, the incidence of cancer in humans is much higher than the incidence of cancer in whales, despite whales having more cells than humans. If the probability of carcinogenesis were constant across cells, one would expect whales to have a higher incidence of cancer than humans. Additionally, it is assumed that elephants would have a higher rate of cancer because of the prevalence of cells in comparison to humans.
Theresa Michalak is a German competitive swimmer and former European champion. She represented Germany at the 2012 Summer Olympics in London, competing in the 200-metre individual medley and 4×200-metre freestyle relay. Michalak holds the German records for the 100-metre and 200-metre individual medley. She won the gold medal in the 100-metre individual medley at the 2011 European Short Course Swimming Championships.
ParaHoxozoa is a clade of animals that consists of Bilateria, Placozoa, and Cnidaria. The relationship of this clade relative to the two other animal lineages Ctenophora and Porifera is debated. Some phylogenomic studies have presented evidence supporting Ctenophora as the sister to Parahoxozoa and Porifera as the sister group to the rest of animals. Some studies have presented evidence supporting Porifera as the sister to Parahoxozoa and Ctenophora as the sister group to the rest of animals. The tree below, which is congruent with the vast majority of these phylogenomic studies, conveys this uncertainty with a polytomy.
delta-8-Tetrahydrocannabinol is a psychoactive cannabinoid found in the cannabis plant. It is an isomer of Delta-9-Tetrahydrocannabinol, the compound commonly known as THC. ∆8-THC has antiemetic, anxiolytic, orexigenic, analgesic, and neuroprotective properties.
While acute symptoms of COVID-19 act on the lungs, there is increasing evidence suggests that COVID-19 causes both acute and chronic neurologicalor psychological symptoms. Caregivers of COVID-19 patients also show a higher than average prevalence of mental health concerns. These symptoms result from multiple different factors.
