Genetic and lifestyle factors linked to brain network aging, study reveals

Research highlights the impact of genetic and lifestyle factors on a brain network particularly sensitive to aging, schizophrenia, and Alzheimer's disease, using data from nearly 40,000 UK Biobank participants to investigate modifiable risk factors and genetic associations.

Cells' built-in stopwatch safeguards mitosis

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from one parent cell to the next generation of two daughter cells.

Study reveals neurological effects of reused frying oils

A new study found higher levels of neurodegeneration in rats that consumed reused deep fried cooking oils and their offspring compared to rats on a normal diet. Deep frying, which involves completely submerging food in hot oil, is a common method of food preparation around the world.
