DOI: 10.1016/S2589-7500(22)00063-2 The miseducation of algorithms is a critical problem; when artificial intelligence mirrors unconscious thoughts, racism, and biases of the humans who generated these algorithms,...

Credit: National Cancer Institute An artificial intelligence (AI) tool developed by Cedars-Sinai investigators accurately predicted who would develop pancreatic cancer based on what their CT scan images looked like years prior to being diagnosed with the disease. The findings,...
by Victoria University of Wellington Credit: Pixabay/CC0 Public domain During her Ph.D., Dr. Qurrat Ul Ain developed a computer-aided diagnostic system that can identify certain characteristics of the disease from a photograph of a skin lesion. “Skin cancer has certain unique visual features that help to differentiate it from normal skin,” Dr. Qurrat Ul Ain...
The brain is often called a black box, but any neuroscientist who has looked inside knows that’s a sobering understatement. Technological advances are making our neural circuitries increasingly accessible, allowing us to closely watch any number of neurons in action. And yet the mystery of the brain only deepens. What’s the meaning embedded in the collective chorus...
The machine-learning model could help scientists speed the development of new medicines. Antibodies, small proteins produced by the immune system, can attach to specific parts of a virus to neutralize it. As scientists continue to battle SARS-CoV-2, the virus that causes Covid-19, one possible weapon is a synthetic antibody that binds with the virus’ spike proteins to...
By Steven Zeitchik Yesterday at 7:00 a.m. EST When Regina Barzilay returned to work after her breast cancer leave seven years ago, she was struck by an unexpected thought. The MIT artificial-intelligence expert had just endured chemotherapy, two lumpectomies, and radiation at Massachusetts General Hospital, and all the brutal side effects that come along with...
UNIVERSITY OF EXETER Artificial intelligence can predict which people who attend memory clinics will develop dementia within two years with 92 percent accuracy, a largescale new study has concluded. Using data from more than 15,300 patients in the US, research from the University of Exeter found that a form of artificial intelligence called machine learning...
by Massachusetts General Hospital Credit: Unsplash/CC0 Public Domain In a recent study published in Nature Biomedical Engineering, a team led by researchers at Massachusetts General Hospital (MGH) has demonstrated that magnetic resonance imaging (MRI) and artificial intelligence (AI) can be used to detect early signs of tumor cell death in response to a novel virus-based cancer...
by Helmholtz Association of German Research Centres Artificial intelligence makes it possible to classify automatically bone marrow cells like the ones pictured here. This method is an important step in the diagnosis of blood diseases. Credit: Helmholtz Munich / Carsten Marr Every day, cytologists around the world use optical microscopes to analyze and classify samples of...
UNIVERSITY OF SOUTHERN CALIFORNIA Cognitive behavioral therapy (CBT) is one of the most common types of talk therapy in the United States. There are 11 criteria that cognitive behavioral therapists-in-training are normally judged on. What if their skills could be evaluated and improved with feedback from AI? This is the crux of new research from...
