Elevated blood pressure, high cholesterol and diabetes increase the risk of heart disease. But a large study today reveals that in people with these conditions, increasing activity levels is associated with a reduced likelihood of heart events and mortality. The research is presented at ESC Preventive Cardiology 2021, an online scientific congress of the European Society of Cardiology (ESC).
Large-scale supercomputer simulations at the atomic level show that the dominant G form variant of the COVID-19-causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, compared to other variants.
A synaptically localized long noncoding RNA proves to be an important regulator of neural plasticity.
In a new Yale-led study, researchers find that autism may develop in different regions of the brain in girls than boys and that girls with autism have a larger number of genetic mutations than boys, suggesting that they require a larger "genetic hit" to develop the disorder. The findings appear in the April 16 edition of the journal Brain.
The new cutoff values for a metric widely used by geriatricians, physical therapists and nutritionists are more accurate, facilitate early diagnosis and contribute to preventive treatment.
More than 70% of neurological diseases, including Alzheimer's disease and the concussion-related disorder CTE, are believed to be fueled by protein clusters called tau aggregates. A new study sheds light on how they damage brain cells and could ultimately lead to new therapies for such "tauopathies."
Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.
Scientists at Sanford Burnham Prebys have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers' understanding of factors that affect disease severity and also suggest possible therapeutic options. The genes in question are related to interferons, the body's frontline virus fighters.
One of the most comprehensive statistical analyses of drivers of food insecurity across 65 countries has concluded that household income consistently explains more discrepancy in food security than any other factor, including agricultural land resources and production.
Results suggest vaccination against COVID-19 remains crucial even in young adults who were previously infected.
