A new study suggests that the reason why aging is associated with obesity lies in specific neurons found in the brain [1]. Tell that to the brain It is often hard to lose weight, and it becomes harder with age. While it seems simple enough to eat less, signals in the brain are telling people to...

In Cell, researchers have published a paper outlining the different ways in which brain cells slowly mutate with aging. The genomic damage of aging Cells accumulate mutations with aging, including brain cells [1]. However, as these researchers note, most previous research into these mutations has been on neurons rather than the glia, the helper cells...

In an in-depth paper in Nature, researchers have explained how astrocytes, helper cells that provide crucial brain functions, epigenetically remember things in a way that encourages inflammation. Traumatized cells Long-lived immune cells, including T cells and B cells, can remember foreign pathogens [1]. This is why people can become immune to diseases after catching them...

Publishing a study in GeroScience featuring people over 80 years old, researchers have described a link between physical fitness and maintenance of specific brain functions. Executive functions This paper begins with a description of executive functions, the basic abilities involved in performing the fundamental goal-oriented behaviors necessary for everyday life. It is obvious how this...

Scientists have discovered a small molecule that effectively kills glioblastoma, a highly aggressive and untreatable brain cancer, in cellular cultures [1]. When acidic means deadly Despite scientists’ best efforts, some types of cancer remain almost as deadly as ever. This includes the dreaded glioblastoma, a type of brain cancer that is especially aggressive and resistant...

In a recent study published in Aging Cell, researchers found similarities between glioblastoma and Alzheimer’s disease patients in their gene expression and protein profiles [1]. Brain tumors and neurocognitive dysfunction The majority of patients with brain tumors develop irreversible, progressive neurocognitive dysfunction, sometimes long after their treatment [2-4]. It reduces their quality of life and,...
