Researchers have discovered a previously unknown process by which pathogens enter a cell with physical force, breaching the body's immune defenses that prevent infection. The findings suggest that brain injury and repair processes persist for years after players end collision sports careers, and lead to long-term cognitive problems such as memory loss. In a new study, scientists add a parameter to artificially intelligent algorithms to make it easier to find a wine that precisely matches a person’s tastebuds. By identifying ribosomal RNAs exclusively present in diseased, dying, and dead sponges, the team found three distinct Vibrio species. In the largest study to date of ancient dental calculus, scientists at Penn State suggest that the Black Death, which killed 30 to 60 percent of the European population, may have shifted the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans. Researchers have reversed the evolution of a class of antibiotics to gain insights for the development of new drugs. |
