Obstacles for breast cancer prevention in high-risk Black women

A new study found that high-risk Black women face significant barriers to breast cancer prevention, including a focus on spiritual well-being over risk management and limited access to specialists. Women in this group were less likely to prioritize preventive measures and more likely to report competing priorities in their lives.

New study unveils epigenetic ‘traffic lights’ controlling stop and go for gene activity

A major new study in the journal Nature reveals a 'traffic light' mechanism controlling genetic activity within cells. The research describes how epigenetic changes act as a stop-go signal determining whether a gene should be read, and how this system could potentially be targeted by cancer drugs already in development.

Despite misperceptions, hormone therapy may actually reduce risk of lung cancer

A large new study found that hormone therapy does not increase the risk of lung cancer development in postmenopausal women and may even reduce it. The study, based on data from over 38,000 women, suggests that higher cumulative dosages of hormone therapy are associated with a lower risk of developing lung cancer.

Research finds that deposit insurance and bank runs in reverse

Researchers found that deposit insurance motivates people to keep deposits immediately below the insured threshold, leading to 'bunching' behavior. An increase in insured deposits also causes savers to change their asset allocation and increase their deposits.
