The new ring system is around a dwarf planet called Quaoar. It is about half the size of Pluto and orbits the Sun beyond Neptune. Scientists have found a new set of rings around a dwarf planet at the edge of the Solar System. The ring system orbits far further away than is common for other ring systems, bringing into doubt existing ideas about the formation of ring systems. Quaoar, a dwarf planet around the size of Pluto that circles the Sun beyond Neptune, is where this ring system is [...]

A study of 941 participants in the English Longitudinal Study of Aging (ELSA) who passed away between 2007 and 2018 (445 women, 496 men) found the following results. Men who grew up with an overprotective father and little independence may have a 13% greater chance of dying before their eightieth birthday. The probability of dying before the age of 80 may rise by 22% in women who had an overprotective father. On the other hand, the risk may drop by 14% for women whose mothers provided them [...]

A new study published in a peer-reviewed journal indicates that viral and human proteins interact to drive protein migration from the nucleus to the cytoplasm. New research says that the new coronavirus tricks cells into making copies of itself. The discovery, according to researchers, may help with COVID-19 treatment development. The research was carried out by scientists from the State University of Campinas (UNICAMP) and the University of So Paulo (USP) in Brazil, and the results were [...]

Both species live in waters about 25 miles north of the Brazilian city of Apu, on the verge of human encroachment into the Amazon jungle. In an article published today in the Zoological Journal of the Linnean Society, Smithsonian researcher Murilo Pastana and his colleagues describe two new Amazonian fish species, one with spectacular red-orange fins and the other so small it is technically designated a miniature fish species. Both species live in waters about 25 miles north of the [...]

The activity rates of all biological creatures, both plant and animal, are influenced by the gravitational tides produced by the orbital mechanics of the sun, Earth, and moon, says new study. Observations of changes in autoluminescence generated by seed germination in cycles regulated by gravitational tides motivated researchers at the University of Campinas in Brazil to pursue research. The gravitational tides produced by the orbital mechanics of the Sun-Earth-Moon system are intimately [...]

Small doses of a component found in some reptiles may be able to inhibit the formation of thrombi that cause cerebrovascular events and can even become a new option for tumor reduction. A team of Brazilian and Belgian scientists has developed a molecule based on one of the proteins in the venom of a South American snake. This sample facilitates the modulation of blood coagulation, so it could be used in medications to treat thrombosis or in healing dressings. Experts have synthesized the [...]

A group of researchers discovers a certain association between people who have had dengue and the risk of contagion from Covid-19 Dengue is a disease caused by a virus. It is a common pathology that each year causes many affected. In this sense, it is estimated that some 400 million people fall ill from dengue every year. Although, dengue is caused by the bite of infected mosquitoes. That is, the mosquito acts as a reservoir for the virus and transmits it to people through the bite. Anyone [...]
