Two strains of the bacterium causing tuberculosis have only minor genetic differences but attack the lungs in completely different fashion, according to Rutgers researchers. New Jersey, April 18, 2022.- The findings, published in the journal Nature Communications, could help break the cycle of rapid transmission of TB, the second-leading infectiousContinuar Leyendo
The ability to visually represent artefacts, whether inorganics like stone, ceramic and metal, or organics such as bone and plant material, has always been of great importance to the field of anthropology and archaeology. For researchers, educators, students and the public, the ability to see the past, not only readContinuar Leyendo
A new University of Gothenburg study has paved the way for the first drug treatment for sleep apnea. Compared to before receiving the treatment, breathing pauses decreased with on average more than 20 per hour for patients given the drug. Gothenburg, April 16, 2022.- The treatment that has been testedContinuar Leyendo
