The Ervebo vaccine has proved safe and effective against the more common Zaire strain of the Ebola virus, and World Health Organization experts say early data, notably from animal trials, suggest it may also offer some protection against the rarer Bundibugyo strain, which is spre

In a world first, scientists led by a team from Stanford University have created 16 viable viruses that do not exist in nature and were designed by AI. Their experiment, which is published in Science, could help in the fight against superbugs by allowing researchers to design cus

Nesta semana dois novos casos de remissão da infecção pelo vírus HIV após transplante de células-tronco foram anunciados durante a 26ª Conferência Internacional da Aids, no Rio de Janeiro. Com isso, chega a 13 o número de pacientes infectados com HIV que não tiveram vírus detecta

A Sociedade Brasileira de Imunizações (SBIm) lançou a campanha Todos contra o VSR – Proteção desde o Início. O objetivo é ampliar o conhecimento de gestantes e da população sobre a importância da imunização contra o vírus sincicial respiratório (VSR), bem como fortalecer o conhec

An international team of researchers has developed an innovative strategy for producing new vaccines. They created a genetically modified version of the chikungunya virus that replicates only once yet still trains the immune system to defend itself without causing disease. In tes

Every time a virus invades a person, it collides with thousands of years of human history. A study led by researchers at the USC Dornsife College of Letters, Arts and Sciences and Howard University suggests that some of the genes involved in the body's immune response today bear

A research team led by Kazuyoshi Murata has discovered that virus-like particles (VLPs) of human norovirus genotype GII.3 are not structurally rigid, but can adopt two distinct conformational states, similar to those previously reported for murine norovirus.

West Nile virus is the most common mosquito-borne disease in the United States—and this summer, cases are rising unusually early. According to the U.S. Centers for Disease Control and Prevention (CDC), the country has recorded its highest number of West Nile cases this early in t

The AI system makes genetically distant versions of a bacteria-killing virus. O recorte ajuda a contextualizar a pauta dentro de IA.

Scientists made 16 successful viruses that had their genetic code designed by artificial intelligence. O recorte ajuda a contextualizar a pauta dentro de Cultura.

Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein. In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a simple supplement could have powerf

Scientists have uncovered a surprising way that “jumping genes” may move between species and speed up evolution. While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from a tiny predatory bacterium ins
