Sports concussions, Parkinson’s disease and hormone therapy for cancer all can have memory loss as symptoms. But can the biochemical processes of each reveal anything about the memory loss associated with Alzheimer’s disease? Rong Xu recently received a total of $5 million from the National Institute of Health’s (NIH) National […]

There is a large, untapped potential for developing drugs against cancer, fibrosis and cardiovascular diseases by targeting a family of receptors known as Frizzleds, researchers at Karolinska Institutet in Sweden believe. In a new study published in Science Signaling, they identify how these receptors are activated in the cell membrane and […]

Purdue University research shows the antidote can effectively remove acrolein, a neurotoxin produced in the body that is directly correlated with Parkinson’s disease. A World War II chemical weapon antidote is shown to be effective combating a new enemy: Parkinson’s disease. Parkinson’s is characterized by the steady and progressive loss […]

Epigenetics is the expression and control of genes. The epigenetics involved in the inner ear is a critical part of the mystery of hearing. A team led by Prof. Karen B. Avraham, Vice Dean of the Sackler Faculty of Medicine at Tel Aviv University, has now created the first map of “methylation” — one […]

The National Institutes of Health announced that enrollment for the Adolescent Brain Cognitive Development (ABCD) Study is now complete and, in early 2019, scientists will have access to baseline data from all ABCD Study participants.
