Investigators have discovered that arsenic in combination with an existing leukemia drug work together to target a master cancer regulator. The team, led by researchers at Harvard Medical School and the Cancer Center at Beth Israel Deaconess Medical Center, is hopeful that the discovery could lead to new treatment strategies […]

More than two-thirds of women with ovarian cancer have high-grade serous carcinoma (HGSC). Up to 90 percent of HGSCs are not detected until they are beyond the ovaries or fallopian tubes, at which point it may not be possible to fully remove the tumor. Many of these cancers are now […]

Eating a diet that is rich in fruits, vegetables and whole grains and low in added sugar, sodium and processed meats could help promote healthy cellular aging in women, according to a new study published in the American Journal of Epidemiology. “The key takeaway is that following a healthy diet […]

A new technology developed by Purdue University researchers allows different concentrations of a drug or a chemical to be targeted at different areas of the same cancerous tissue in the laboratory. The discovery may help the more than 1.7 million people the National Cancer Institute predicts will be diagnosed with […]

A special strain of soil bacteria has the paradoxical ability to produce highly toxic compounds to protect itself from other organisms without harming itself. A collaboration that includes scientists from the Department of Energy’s (DOE) Argonne National Laboratory has discovered that the bacteria performs this feat by confining the toxic […]

Queen and worker honeybees are almost genetically identical but are fed a different diet as larvae. The researchers have found that specific protein patterns on their genome play an important role in determining which one they develop into. These proteins, known as histones, act as switches that control how the […]

Researchers from the University of Oxford, in collaboration with researchers from Canada and the Universities of Bristol and London, have used advanced magnetic resonance imaging to investigate whether factors such as blood pressure, fitness, smoking and alcohol intake during young adult life are associated with changes in the blood vessels […]
