Many women struggling to have a baby turn to in-vitro fertilization to improve their chances, and then face further uncertainty and anxiety when confronted with the decision of whether to use frozen or fresh embryos. A new study by a researcher at Yale School of Public Health and co-authors in […]

Researchers at the Case Comprehensive Cancer Center (CCCC) at Case Western Reserve University have helped develop a computer program to find new indications for old drugs. The computer program, called DrugPredict, matches existing data about FDA-approved drugs to diseases, and predicts potential drug efficacy. In a recent study published in Oncogene, the […]

Attempts to eradicate cancer are often compared to a “moonshot” — the successful effort that sent the first astronauts to the moon. But imagine if, instead of Newton's second law of motion, which describes the relationship between an object's mass and the amount of force needed to accelerate it, we […]

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have, for the first time, coaxed human stem cells to become sensory interneurons — the cells that give us our sense of touch. The new protocol could be a step toward stem cell–based therapies to […]

In the nervous system, a synapse is the place where signals are passed from neuron to neuron. The recently published paper focuses on synaptic dysfunction and its impact on dementia severity and cognition in the elderly with various dementia diagnoses. In addition to Alzheimer´s disease, the Lewy body dementias are the […]

New national research led by Jonathan Lass of Case Western Reserve University School of Medicine has found that corneal donor tissue can be safely stored for 11 days before transplantation surgery to correct eye problems in people with diseases of the cornea. This is four days longer than the current […]

Why does immunotherapy achieve dramatic results in some cancer patients but doesn’t help others? It is an urgent and vexing question for many cancer specialists. Now, two research groups from Harvard Medical School based at Dana-Farber Cancer Institute have independently discovered a genetic mechanism in cancer cells that influences whether […]

University of Alberta researchers have discovered a mechanism that may make cancer cells more susceptible to treatment. Post-doctoral fellow Mohammad Ali and his research team found that the protein RYBP prevents DNA repair in cancer cells, including breast cancer, which in turn could make chemo or radiation therapy more effective.
