Researchers found that chimpanzees learn and adopt specific techniques to solve problems, demonstrating a form of culture. The study shows that chimpanzees have a tendency to conform to their group's norms, even when they know alternative methods exist.
Scientists have identified a new mechanism by which Listeria invades non-phagocytic cells, revealing similarities between phagocytosis and endocytosis. Researchers found that Listeria uses endocytosis to transport tagged proteins inside the cell.
A large study found no link between MS risk and birth order position, contradicting the hygiene hypothesis. In fact, individuals with MS tended to be born later in larger sibships than expected.
Researchers identified a new gene, BRIP1, associated with Fanconi anemia's hallmark chromosomal instability. The protein BACH1 helps DNA unwind for repair, and BRIP1 mutations disrupt this process.
A new statistical analysis of paroxetine trials reveals a significantly higher rate of suicide attempts among adults compared to placebo groups. The study confirms that all SSRIs increase suicidal tendencies in depressed adults, with increased intensity over time.
Researchers have found that few B cells are needed to trigger an effective T-cell immune response in certain cancers. A personalized vaccine used in a Phase I study resulted in an impressive 89% survival rate for patients with mantle cell lymphoma. The study paves the way for future vaccine use in other hematological cancers.
Researchers at NIA discover new gene FANCM linked to Fanconi anemia and increased cancer risk. The gene plays crucial role in DNA repair machinery, offering potential targets for treatment.
Researchers found chimpanzees learn by observation and adopt traditions through ape-to-ape transmission. Chimpanzee groups conform to established norms, even when alternative methods exist, suggesting an ancient origin for cultural conformity in non-human primates.
