Two new studies reveal how bacteria infiltrate tumors and could be helping tumors progress and spread and suggest a link between oral health and cancer, as microbes in the mouth are associated with cancers elsewhere in the body. The two articles focus on an oral bacterium called Fusobacterium nucleatum, which has been linked to colorectal cancer.

Immune checkpoint inhibitors such as Keytruda and Opdivo work by unleashing the immune system's T cells to attack tumor cells. Their introduction a decade ago marked a major advance in cancer therapy, but only 10% to 30% of treated patients experience long-term improvement. New findings could now bolster the effectiveness of immune-checkpoint therapy.

One aspect of hormonal contraceptives' effect on the teenage body remains a mystery -- whether and how they modify the developing brain. New research in young rats links synthetic hormones found in birth control pills, patches and injections with disordered signal transmission between cells in the prefrontal cortex, an area of the brain that continues to develop throughout adolescence.

While previous studies have linked commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, to benefits related to cardiovascular, metabolic and neurological health, new research has found NR could actually increase the risk of serious disease, such as development of breast cancer and brain metastasis. [Editor's Note (Nov. 16, 2022): The headline and first paragraph have been updated to clarify the findings of the study.]
