Identifying the cause of mysterious heart disease in women
Prof. Kovacic said, “SCAD is still a relatively little-known disease, but it has a huge impact and is behind a quarter of all heart attacks in women under 50. We urgently need to learn more about this disease and discover what is causing it.”
He added, “This disease can not only be life-threatening, but it can reoccur without warning in some patients.”
The researchers are the first outside of the United States to join the iSCAD Registry, a global collaboration of researchers and patients studying the characteristics and pathogenesis of SCAD.
Scientists Hacked Human Cells to Make Insulin, And It Reversed Diabetes in Mice
Scientists have repurposed human stomach cells into tissues that release insulin in response to rising blood sugar levels in a breakthrough that promises an effective way to manage conditions such as type 1 diabetes.
The experiment, led by researchers from Weill Cornell Medicine in the US, revealed transplants of gastric insulin-secreting (GINS) cells reversed diabetes in mice.
Pancreatic beta cells normally do the job of releasing the hormone insulin in response to elevated sugar levels in the blood. In people with diabetes, these tissues are damaged or die off, compromising their ability to move glucose into cells for fuel.
Scientists are closer to understanding how much meditation training is needed to improve brain–computer interface performance
Mindfulness-based awareness training can help people learn to better control brain-computer interfaces. But a new study has found that a single guided mindfulness meditation exercise isn’t enough to boost performance. The findings, published in Frontiers in Human Neuroscience, suggest that a longer period of meditation is needed in order for people to experience observable improvements.
The authors of the research are interested in exploring the potential benefits of using mindfulness meditation as a training tool to improve the performance of brain-computer interfaces, which allow individuals to control machines or computers directly from their brain, bypassing the traditional neuromuscular pathway. These devices have the potential to greatly benefit people with conditions such as spinal cord injuries, stroke, and neurodegenerative diseases like amyotrophic lateral sclerosis (ALS).
Previous studies have shown that one of the most effective signals for brain-computer interface control is the sensorimotor rhythm produced in the primary sensorimotor areas during motor imagery. However, not everyone is able to effectively control brain-computer interfaces, with approximately 20% of the population being “BCI-inefficient” even with extensive training. Therefore, researchers are looking for ways to improve performance, and one potential method is through meditation.
