It’s true that dogs demand a lot from their owners—but they also offer a lot in return.
Are you on the fence about getting a dog? Worried that he’ll pee on the carpet or chew the furniture? Well, he might—at least at first. But he’ll also add so much joy and love to your life. And the benefits of having a dog don’t stop at him being adorable and snuggly; according to a growing body of science, dogs can be good for your physical and mental health, too. Here’s what the research has to say:
Novartis is offering a $250,000 prize to fund development of pioneering innovation with great potential in advancing Assistive Tech for Multiple Sclerosis. Applications will be accepted until January 10, 2020, and the winners will be announced during a panel discussion among experts in the field at SXSW in Austin, TX.
This study involved 4,717 participants from two different community-based cohorts. A meta-analysis of both cohorts showed that elevated sCD14 was associated with a 12 percent increased risk of dementia as people got older. Higher levels of sCD14 were also associated with accelerated brain aging in both cohorts, a faster progression of age-related brain atrophy, and a more rapid decline of executive functions.
The authors sum up their findings: “sCD14 is an inflammatory marker related to brain atrophy, cognitive decline, and incident dementia.”
“Higher levels of sCD14 were associated with markers of brain aging and injury, such as total brain atrophy and a decline in executive functioning—the decision-making needed for many activities of daily life,” first author Matthew Pase, of the Florey Institute for Neuroscience and Mental Health in Melbourne, Australia, said in a news release.
Scientists have developed a new gene-therapy technique by transforming human cells into mass producers of tiny nano-sized particles full of genetic material that has the potential to reverse disease processes.
Though the research was intended as a proof of concept, the experimental therapy slowed tumor growth and prolonged survival in mice with gliomas, which constitute about 80 percent of malignant brain tumors in humans.
The technique takes advantage of exosomes, fluid-filled sacs that cells release as a way to communicate with other cells.
Optogenetics, a tool for controlling neurons with light, has given neuroscientists the ability to flip brain cells on and off more or less at will, revolutionizing neuroscience.
Yet the technique faces a fundamental challenge: To study all but the outermost part of the brain, researchers need to implant fiber optics or other invasive devices to deliver light deep into the brain.
Now, in Proceedings of the National Academy of Sciences, Stanford researchers report that they’ve found a less invasive way to do so: injectable nanoparticles that convert sound waves, which can easily penetrate into the brain, into light.
