According to new research published in the Annals of Oncology, deaths due to ovarian cancer have declined worldwide from 2002 to 2012. The authors believe the main reason for this is the use of oral contraceptives, along with “declines in menopausal hormone use…as well as improved diagnosis, management and treatment.”

Do You Know Scientists have Found Cancer in a Million-Year-Old Fossil?
A team of international researchers in South Africa have identified the earliest known incidences of cancer in the hominin fossil record. Two research articles in the South African Journal of Science describe a malignant osteosarcoma in a foot bone, dated at around 1.7 million years old, and benign neoplasms at nearly 2 million years old in hominin vertebrae. The malignant neoplasia predates the last evidence of the disease by nearly 200,000 years. While modern habits and lifestyles are responsible for many instances of cancer, it is apparent that the disease has been around for longer than we thought.
Did You Know that Running Could Help Improve Your Memory?
A new study published in Cell Metabolism has found that running releases a protein that is associated with improved memory in mice in laboratory conditions. This protein, called cathepsin B (CTSB), was known to help sore muscles recover and is secreted by muscle during exercise. The researchers found that adding CTSB to neurons in petri dishes led to brain cell production in mice. Furthermore, they showed a positive correlation between running and increased levels of the CTSB protein in mouse, monkey, and human subjects. Continue reading
