New research from the Registry of Senior Australians (ROSA) research center based at SAHMRI has revealed one in five people living in Australian residential aged care (RAC) facilities has a significant oral health problem, with little access to dental services.
A recent study by the University of Eastern Finland shows that barriers to accessing social and medical services among older immigrants and immigrants with dementia in Finland are interconnected. The study, conducted among professionals working with older immigrants and immigrants with dementia, was published in the Journal of Cross-Cultural Gerontology.
The measles outbreak that started in Texas in late January continues to grow. As of March 18, 2025, confirmed cases in the outbreak, which now spans Texas, New Mexico and Oklahoma, reached 321, surpassing the number of confirmed cases recorded for all of the U.S. in 2024. The vast majority of cases are in people who are not vaccinated. Meanwhile, a lack of clarity from health authorities is leaving people with questions about whether they need to get revaccinated.
For the first time, scientists have systematically analyzed somatic mutations in stomach lining tissue to unpick mutational processes, some of which can lead to cancer. The team also uncovered hints of a potential new cause of stomach cancer that needs further research.
A team at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) led by Dr. Andrés Hidalgo has discovered a specialized population of neutrophils in the skin that produce extracellular matrix, helping to maintain the skin’s resistance and integrity.
A vaccine’s ability to generate long-lasting, high-affinity antibodies hinges on a delicate balance. Upon exposure to a vaccine or pathogen, B cells scramble to refine their defenses, rapidly mutating in hopes of generating the most effective antibodies. But each round of this process is a roll of the genetic dice—every mutation has the potential to improve affinity; far more often, however, it degrades or destroys a functional antibody. How do high-affinity B cells ever beat the odds?
By revealing for the first time what happens in the brain when an animal makes a mistake, Johns Hopkins University researchers are shedding light on the holy grail of neuroscience: the mechanics of how we learn.
A new study explains how a parakeet’s brain helps it to mimic human words. By recording for the first time the brain activity of parakeets as they made sounds, a research team at NYU Grossman School of Medicine found that their brains generate patterns seen before only in humans as they speak.
Germinal centers are high-speed evolution machines. Tiny clusters in the lymph nodes, germinal centers refine antibodies through mutation and expansion until they produce high-affinity B cells adapted to keep different pathogens in check. But rapid evolution should come at a cost.
To uncover what drives sexual behavior in animals, researchers studied the brain activity of male mice throughout the series of actions involved in sex leading up to ejaculation. Their results, published in Neuron, show that the intricate dance in the brain area responsible for pleasure between two chemicals—dopamine and acetylcholine—controls the progression of sexual behavior.
