Penn doctoral student Michael Barnett admits he was “obsessed” with Pokémon as a child, spending hours with Pikachu and the gang. So, as he and former Stanford colleague Jesse Gomez discussed a paper about which brain regions light up when young macaques view letters, cartoons, and Tetris pieces, they had an idea. “We […]

Earth’s atmosphere shields life on the ground from cosmic radiation that can damage DNA.  Astronauts in space have no such protection, and that puts them at risk. An investigation on the International Space Station examines DNA damage and repair in space in order to help protect the long-term health of […]

In 2009, disagreement in the health community arose following a recommendation from the United States Preventive Services Task Force (USPSTF) against routine mammogram screening for women ages 40-49 who are at average risk for breast cancer. Then, in 2015, the American Cancer Society (ACS) updated its 2003 breast cancer screening […]

Technology reveals previously undetectable protein signaling activity in diabetes, cancer Proteins are the workhorses of the cell. Their activity is often controlled by adding or removing chemicals called phosphates, like switching an electrical current on or off. Measuring how many proteins are phosphorylated, or turned on, has been a roadblock […]

Some research suggests that one reason people with obesity overeat is because they don’t enjoy food—especially sweets—as much as lean people. But it’s not understood if obesity itself or eating certain foods causes taste changes, or how those changes impact appetite and obesity. For clues, University of Michigan researchers turned […]

Several years ago, MIT neuroscientists showed that they could dramatically reduce the amyloid plaques seen in mice with Alzheimer’s disease simply by exposing the animals to light flickering at a specific frequency. In a new study, the researchers have found that this treatment has widespread effects at the cellular level, […]

A new algorithm developed by MIT researchers takes cues from panoramic photography to merge massive, diverse cell datasets into a single source that can be used for medical and biological studies. Single-cell datasets profile the gene expressions of human cells — such as a neurons, muscles, and immune cells — to […]

MIT researchers have performed the first comprehensive analysis of the genes that are expressed in individual brain cells of patients with Alzheimer’s disease. The results allowed the team to identify distinctive cellular pathways that are affected in neurons and other types of brain cells. This analysis could offer many potential […]

Oncologists may soon have an accurate and inexpensive way of differentiating between types of ovarian cancer that will improve how patients are treated, thanks to findings from a national research study co-led out of the University of Alberta. “One of the issues with ovarian cancer is that we cannot fully decipher between […]

Repetition can be useful if you’re trying to memorize a poem, master a guitar riff, or just cultivate good habits. When this kind of behavior becomes compulsive, however, it can get in the way of normal life—an impediment sometimes observed in psychiatric illnesses like Tourette’s syndrome and autism spectrum disorders. […]

While it’s reported that chronic disruptions of circadian rhythms, or internal body clocks, can lead to an increased risk of cancer, the underlying mechanisms by which the disturbances promote tumor growth had been largely unknown. In a study published in the journal PLOS Biology, researchers at Penn Medicine show circadian disruptions trigger […]

Cleft lip and palate (CL/P) is the second most common birth defect in the world, affecting 1 in 700 live born babies. While the exact cause of CL/P is not well understood, investigators think it could be the result of a combination of genetics and environment. Cleft lip and palate […]

Induced pluripotent stem (iPS) cells are among the most important tools in modern biomedical research, leading to new and promising possibilities in precision medicine. To create them requires transforming a cell of one type, such as skin, into something of a blank slate, so it has the potential to become […]

Mac, an 8-year-old boxer, lay sedated on a table in the gleaming new radiation treatment room at the Hixson-Lied Small Animal Hospital at Iowa State University.
