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.
