Protein that detects mild may per chance furthermore play a job within the origin and progression of melanoma, search for suggests
Publicado em 15 agosto 2022
Melanopsin (OPN4) is a mild-weight-sensing protein present in pores and skin and retina cells. A novel search for performed at the University of São Paulo (USP) in Brazil suggests that OPN4 can furthermore elevate part within the growth and progression of melanoma, doubtlessly the most aggressive invent of pores and skin cancer.
In experiments with animals and genetically modified cells at the Comparative Physiology of Pigmentation Laboratory belonging to the Institute of Biosciences [...]

“Insect Apocalypse” – Study Reveals Drastic Decline of Aquatic Insect Population in Paraná River Basin
Publicado em 01 outubro 2021Analysis of data collected over 20 years suggests the decline is due to the construction of over 180 dams on the Paraná basin and its tributaries. Research conducted in Brazil for more than 20 years in the Paraná River basin shows a drastic fall in the number of aquatic insects in the region, which is considered well-preserved and distant from the negative impacts of agriculture, cattle breeding, and urbanization. The fieldwork was done by researchers affiliated with the State [...]ver notícia -
Electoral cycles influence destruction of Atlantic rainforest areas in southern and southeastern Brazil
Publicado em 22 setembro 2021A study conducted at the University of São Paulo (USP) in Brazil, and reported in an article published in the journal Conservation Letters, shows that destruction of the Atlantic Rainforest increases in election years. The researchers correlated data from the Electoral High Court (TSE) and MapBiomas, the Brazilian Annual Land Use and Land Cover Mapping Project, for 2,253 municipalities in the southern and southeastern regions covering the period 1991-2014. They [...]ver notícia -
First Genetic Sequencing of Brazilian Pit Viper Completed – Reveals Origin of Toxins in Its Venom
Publicado em 16 agosto 2021In an article published in PNAS, researchers affiliated with Butantan Institute describe the genome of Bothrops jararaca and suggest the origin of genes responsible for toxins in its venom. A group led by researchers at Butantan Institute and funded by São Paulo Research Foundation — FAPESP has completed the first sequencing of a Brazilian snake’s genome. The study is reported in an article published in the journal PNAS. It suggests that the nine genes that encode toxins [...]ver notícia -
Tree falls during dry season in São Paulo City are due to poor management, study suggests
Publicado em 12 agosto 2021Trees fall every day in São Paulo, Brazil, the largest and most populous city in Latin America, but most tree falls occur in the rainy season owing mainly to the effects of temperature, strong winds and heavy rain. When trees fall in the dry season, the main direct cause is not weather but a lack of management and adequate conditions for the survival of street vegetation. These are the key findings of a studypublishedby a group of Brazilian researchers in the journalTrees - Structure [...]ver notícia -
Birds that disperse more types of seed have better evolutionary chances
Publicado em 12 agosto 2021More than 70% of plant species that produce flowers depend on birds to disperse their seeds. Birds feed on fruit from a wide array of different plants, and bird-plant interactions configure a welter of complex networks. A study conducted at the University of São Paulo’s Institute of Biosciences (IB-USP) in Brazil shows that the evolutionary stability of each bird species depends on the position it occupies in these networks, increasing in step with the number and centrality of [...]ver notícia -
2/3 of Calories in Children and Teen Diets Comes From Ultraprocessed Foods
Publicado em 10 agosto 2021Ultraprocessed foods, including sugary snacks, now make up 2/3rds of kids’ and teens’ diets. New study in JAMA also found kids and teens eat less unprocessed and minimally processed foods. The calories that children and adolescents consumed from ultraprocessed foods jumped from 61% to 67% of total caloric intake from 1999 to 2018, according to a new study from researchers at the Friedman School of Nutrition Science & Policy at Tufts University. Published August 10, 2021, in [...]ver notícia -
Breakthrough: Magnetizing a Material Without Applying an External Magnetic Field
Publicado em 03 agosto 2021Researchers propose a method of magnetizing a material without applying an external magnetic field. The study shows that the phenomenon can be produced by means of adiabatic compression, without any exchange of heat with the environment. The process aligns the spins of the material’s particles and magnetizes the system. Magnetizing a material without applying an external magnetic field is proposed by researchers at São Paulo State University (UNESP), Brazil, in an article [...]ver notícia -
Researchers propose a method of magnetizing a material without applying an external magnetic field
Publicado em 29 julho 2021Magnetizing a material without applying an external magnetic field is proposed by researchers at São Paulo State University (UNESP), Brazil, in an article published in the journal Scientific Reports, where they detail the experimental approach used to achieve this goal. The study was part of the PhD research pursued by Lucas Squillante under the supervision of Mariano de Souza, a professor at UNESP’s Department of Physics in Rio Claro. Contributions were also made by Isys Mello, [...]ver notícia -
Microorganisms Discovered on the Rio Grande Rise Are a Basis for Life and a Possible Origin of Metals
Publicado em 26 maio 2021Researchers conducted the first large-scale survey of the microbiota present in the seamount’s ferromanganese crusts, describing bacteria and archaea involved in the nutrient cycle and formation of metals. The abundant biological and mineral diversity of the Rio Grande Rise, a seamount in the depths of the Atlantic Ocean about 1,500 km from the coast of Brazil, is probably due to a great extent to little-known microscopic creatures. Researchers affiliated with the University of [...]ver notícia
