Researchers have discovered a new molecular process that occurs when donor hearts are preserved in cold storage which contributes to failure after transplant, a study in both humans and animals shows. The team also found a therapy to reduce that damage using medication that is typically prescribed for high blood pressure. This discovery has potential to improve the consistent function of donor hearts and extend the distance they can be safely transported in cold storage.

We need to learn our letters before we can learn to read and our numbers before we can learn how to add and subtract. The same principles are true with AI, a team of NYU scientists has shown through laboratory experiments and computational modeling. In their work, researchers found that when recurrent neural networks (RNNs) are first trained on simple cognitive tasks, they are better equipped to handle more difficult and complex ones later on. 

A new study published in Science Advances reveals that a single gene plays a big role in how the liver stores energy, a process that's critical for overall health and for managing diseases like type 2 diabetes. Led by Penn Nursing’s Kate Townsend Creasy, PhD, Assistant Professor of Nutrition Science in the Department of Biobehavioral Health Sciences, the research focuses on the PPP1R3B gene. This gene tells the liver how to handle energy: store it as glycogen (a form of sugar) or triglycerides (a type of fat).

In the largest clinical genomic profiling study of non-Hispanic Black men with metastatic prostate cancer to date, researchers from Moffitt Cancer Center, University of Pennsylvania, University of California Los Angeles and the Veterans Affairs (VA) National Precision Oncology Program found key differences in tumor biology between non-Hispanic Black and non-Hispanic white veterans, but similar survival outcomes when both groups had equal access to care.
