Cutting-edge research has uncovered how chronic stress disrupts the balance of gut microbiota to speed up the progression of colorectal cancer (CRC), opening new avenues for CRC prevention and treatment.

By eliminating certain gut bacteria and inducing stress, researchers were able to conclude a relationship between stress and gut microbiota in the progression of CRC, identifying a particular bacterial species as a potential therapeutic target.

Presenting the study at UEG Week 2024, lead researcher Dr...

Harvard University researchers have identified the biological mechanism of how chronic stress impairs hair follicle stem cells, confirming long-standing observations that stress might lead to hair loss.

In a mouse study published in the journal Nature, the researchers found that a major stress hormone causes hair follicle stem cells to stay in an extended resting phase, without regenerating the hair follicle and hair...
