In a study using human breast cancer cells, scientists say they have potentially identified immune system white blood cells that appear to be the closest neighbors of breast cancer cells that are likely to spread. The researchers say the finding, focused on a white blood cell called a macrophage, may provide a new biological target for immunotherapies designed to destroy spreading cancer cells that are often markers for worsening disease.

Heart failure during pregnancy is a dangerous and often under-detected condition because common symptoms -- shortness of breath, extreme fatigue and trouble breathing while lying down -- are easily mistaken for typical pregnancy discomforts. A new study showed an artificial intelligence (AI)-enabled digital stethoscope helped doctors identify twice as many cases of heart failure compared to a control group that received usual obstetric care and screening.
