Immune cells attack dangerous bacteria by engulfing them and then releasing a cascade of defense molecules. But some bacteria, known as intracellular pathogens, have evolved to survive this onslaught and replicate inside immune cells. The result can be Salmonella poisoning … Continue reading

Study finds clues to Alzheimer’s disease onset in the aging female brain
In the United States, women make up nearly two-thirds of all diagnosed cases of Alzheimer’s disease. On average, women live about 5 years longer than men, but that life expectancy discrepancy doesn’t likely account for such a large, sex-skewed prevalence … Continue reading
PREVIEW News Feature: To counter the pandemic, clinicians bank on repurposed drugs
Teams are pursuing a dizzying array of therapeutic strategies to stymie COVID-19. It’s not yet clear which approach, or combination of approaches, will work best. *Editor’s Note: We’re providing a preview of this content due to the urgent and rapidly … Continue reading
Fluid dynamics work hints at whether spoken word can spread COVID-19
As of April 3, the Centers for Disease Control and Prevention (CDC) is advising that everyone—sick or healthy—wear masks to prevent the spread of COVID-19. Recent research on how fluids travel from our respiratory tracts when we sneeze, speak, or … Continue reading
New insights into how influenza evades human immunity
Some viruses can only infect people once—measles for example. But other viruses, notably influenza, are capable of infecting repeatedly. Scientists have long puzzled over how the flu virus evades human immunity. Recent work in eLife clarifies exactly how the virus … Continue reading
Journal Club: Amoeba have long-distance preference for certain bacteria, pointing to other cell-sensing insights
How does the microscopic amoeba track down prey in the vastness of the forest floor? Ample research on the soil amoeba Dicytostelium discoideum, affectionately called “Dicty” by researchers, has provided some clues. But the mechanisms behind long-distance sensing of bacterial … Continue reading
Journal Club: Mutation helps Zika virus evolve to more easily infect mosquitoes, spread infection
Scientists discovered the Zika virus over half a century ago. But it wasn’t until recent outbreaks in French Polynesia and South America that the mosquito-borne virus, now associated with Guillain-Barre syndrome in adults and microcephaly in newborn babies, reached epidemic … Continue reading
Journal Club: Macrophages help regenerate ear parts in spiny mice
Salamander tails and fish fins are oft-cited examples of animals’ ability to regenerate a lost limb or organ. But one mammal—the African spiny mouse—has also emerged as a model of regenerative abilities. In a recent study, Ashley Seifert of the University … Continue reading
Journal Club: A new strategy for producing polio vaccine without live virus
The poliovirus, which once paralyzed children across the globe, is nearly eradicated in nature. There were just 74 cases of polio reported in 2015, according to the World Health Organization, down from an estimated 350,000 in 1988. Two vaccines contributed … Continue reading
