Researchers at Karolinska Institutet in Sweden have identified blood-based biomarkers that may determine which patients will benefit from continued hormonal therapy for advanced prostate cancer. The results are published in the journal JAMA Oncology. The researchers envision that this discovery may eventually result in a test that contributes to a more […]

Bioimpedance spectroscopy (BIS) is better than a tape measure for assessing a woman’s risk for developing lymphedema after breast cancer surgery, according to interim results of a study led by Sheila Ridner, PhD, RN, Martha Ingram Professor and director of the PhD in Nursing Science Program at Vanderbilt University School of Nursing. The […]

Researchers identify genetic variants that lead to a severe developmental syndrome. The findings could mean better screening and diagnosis for patients with inherited syndromes. New discoveries from an international team of scientists help explain how protein synthesis gone wrong in developing brains can result in birth defects — including microcephaly, […]

Advancing technology is allowing scientists increasingly to search for tiny signs of cancer and other health issues in samples of patients’ blood and urine. These “liquid biopsies” are less invasive than a traditional biopsy, and can provide information about what’s happening throughout the body instead of just at a single […]

Two proteins central to the pathology of Alzheimer’s disease act as prions — misshapen proteins that spread through tissue like an infection by forcing normal proteins to adopt the same misfolded shape — according to new UC San Francisco research. Using novel laboratory tests, the researchers were able to detect […]

The very first dog received the very first vaccine intended to protect her from cancer. And soon after the 9-year-old Gordon setter named Trilly received her shot, so, too, did Norton, a 9-year-old rat terrier mix. “We’re testing a totally novel way of creating an anti-cancer immune response,” says David Vail, […]

Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs with a breakthrough technique for bioprinting tissues. The new innovation allows scientists to create exquisitely entangled vascular networks that mimic the body’s natural passageways for blood, air, lymph and other vital fluids. The research is featured on the […]

Sperm start their sprint to the ovum when they detect changes in the environment through a series of calcium channels arranged like racing stripes on their tails. A team of Yale researchers has identified a key molecule that coordinates the opening and closing of these channels, a process that activates […]

About a third of us are walking around with the bacteria that causes tuberculosis (TB) in our bodies, but most don’t actually end up with TB. For children living with HIV – about 2 million at last estimate – it’s a different story. They’re much more likely to develop TB, […]

The human brain is “plastic”: it can adapt and rewire itself, often more easily when learning new things related to familiar skills. For example, it is probably easier for a professional tennis player to learn to play badminton than soccer. Seeking to discover basic limits on the brain's plasticity, a […]

Long before scientists test new medicines in animals or people, they study the effects of the substances on cells growing in Petri dishes. However, a 2D layer of cells is a poor substitute for the much more complex 3D structure of tissues in organs. Now, researchers reporting in the ACS […]

Researchers have linked some environmental pollutants with diseases, a decreased life span and signs of premature aging, such as wrinkles and age spots. But can accelerated aging be detected at the cellular level in healthy people exposed to pollutants? Now, researchers in the ACS journal Environmental Science & Technology report that […]
