New AI sees like a human, filling in the blanks

Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions. The team, led by professor Kristen Grauman, Ph.D. candidate Santhosh Ramakrishnan and former Ph.D. candidate Dinesh Jayaraman (now at the University of California, Berkeley) published their results today in the journal Science Robotics.

What are the neurological side effects of CAR T-cell therapy?

The recent advent of chimeric antigen receptor (CAR) T-cell therapy has revolutionized the clinical treatment of cancer. Under the umbrella of immunotherapy, CAR T-cell treatment trains and strengthens a patient's own immune system to attack tumors. Early successes in clinical trials have led to approval of the treatment for recurrent blood cancers, including leukemia and lymphoma.

Once-per-month HIV drugs on the horizon

An HIV diagnosis was once a death sentence, but now people who receive treatment survive for decades with the disease. Keeping the virus at bay usually requires taking a pill every day, which aside from being inconvenient for some, is an unwelcome daily reminder of the disease. That's why drug companies are developing longer-acting, injectable HIV treatments, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

Researchers teach robots handwriting and drawing

An algorithm developed by Brown University computer scientists enables robots to put pen to paper, writing words using stroke patterns similar to human handwriting. It's a step, the researchers say, toward robots that are able to communicate more fluently with human co-workers and collaborators.

Study finds scientific reproducibility does not equate to scientific truth

Reproducible scientific results are not always true and true scientific results are not always reproducible, according to a mathematical model produced by University of Idaho researchers. Their study, which simulates the search for that scientific truth, will be published Wednesday, May 15, in the journal PLOS ONE.

An approach for securing audio classification against adversarial attacks

Adversarial audio attacks are small perturbations that are not perceivable by humans and are intentionally added to audio signals to impair the performance of machine learning (ML) models. These attacks raise serious concerns about the security of ML models, as they can cause them to make mistakes and ultimately generate wrong predictions.

Artificial intelligence shines light on the dark web

Beneath the surface web, the public form of the internet you use daily to check email or read news articles, exists a concealed "dark web." Host to anonymous, password-protected sites, the dark web is where criminal marketplaces thrive in the advertising and selling of weapons, drugs, and trafficked persons. Law enforcement agencies work continuously to stop these activities, but the challenges they face in investigating and prosecuting the real-world people behind the users who post on these sites are tremendous.
