Artificial intelligence is writing fiction, making images inspired by Van Gogh and fighting wildfires. Now it's competing in another endeavor once limited to humans -- creating propaganda and disinformation. When researchers asked the online AI chatbot ChatGPT to compose a blog post, news story or essay making the case for a widely debunked claim -- that COVID-19 vaccines are unsafe, for example -- the site often complied, with results that were regularly indistinguishable from similar claims that have bedeviled online content moderators for years. "Pharmaceutical companies will stop at nothing to push their products, even if it means putting children's health at risk," ChatGPT wrote after being asked to compose a paragraph from the perspective of an anti-vaccine activist concerned about secret pharmaceutical ingredients. When asked, ChatGPT also created propaganda in the style of Russian state media or China's authoritarian government, according to the findings of analysts at NewsGuard, a firm that monitors and studies online misinformation.

Older Americans face a growing loneliness epidemic. Startups are finding ways technology can help. The hard part is bringing them together. The U.S. globally has the highest percentage of older adults living alone, according to Pew Research Center. The Centers for Disease Control and Prevention have long warned that social isolation contributes to numerous health problems, including dementia and depression.

In 2023, radiologists in hospitals around the world will increasingly use medical images--which include x-rays and CT, MRI, and PET scans--that have been first read and evaluated by AI machines. Gastroenterologists will also be relying on machine vision during colonoscopies and endoscopies to pick up polyps that would otherwise be missed. This progress has been made possible by the extensive validation of "machine eyes"--deep neural networks trained with hundreds of thousands of images that can accurately pick up things human experts can't. This story is from the WIRED World in 2023, our annual trends briefing. Read more stories from the series here--or download or order a copy of the magazine.

Keya Medical has launched the DeepVessel FFR, a software device that utilizes deep learning to facilitate fractional flow reserve (FFR) assessment based on coronary computed tomography angiography (CCTA). Cleared by the Food and Drug Administration (FDA), the DeepVessel FFR provides a three-dimensional coronary artery tree model and estimates of FFR CT value after semi-automated review of CCTA images, according to Keya Medical. The company said the DeepVessel FFR has demonstrated higher accuracy than other non-invasive tests and suggested the software could help reduce invasive procedures for coronary angiography and stent implantation in the diagnostic workup and subsequent treatment of coronary artery disease. Joseph Schoepf, M.D., FACR, FAHA, FNASCI, the principal investigator of a recent multicenter trial to evaluate DeepVessel FFR, says the introduction of the modality in the United States dovetails nicely with recent guidelines for the diagnosis of chest pain. "I am excited to see the implementation of DeepVessel FFR. It comes together with the 2021 ACC/AHA Chest Pain Guidelines' recognition of the elevated diagnostic role of CCTA and FFR CT for the non-invasive evaluation of patients with stable or acute chest pain," noted Dr. Schoepf, a professor of Radiology, Medicine, and Pediatrics at the Medical University South Carolina.

ARTIFICIAL intelligence chatbot ChatGPT is causing controversy over its creepy ability to write just like a human. Students are using it to cheat on exams, copywriters are fearing for their jobs, and some people are even using its advice as a replacement for dentists and counselors. AI expert Lisa Palmer spoke exclusively to The U.S. Sun about ChatGPT concerns and the jobs she wouldn't trust it to do right now. Palmer has largely positive views on the AI chatbot and thinks we all should be using it. However, she thinks we need to be wary of its limitations right now and not put pure faith in it to do human jobs.

The rapid emergence of increasingly sophisticated'AI ' programs such as CHATgpt will profoundly impact our world in many ways. That will inevitably include Innovation, especially the front end. But will it ultimately help or hurt us? Better access to information should be a huge benefit, and my intuition was to dive in and take full advantage. I still think it has enormous upside, but I also think it needs to be treated with care.

Chest radiography, also known as a chest X-ray (CXR), is a widely used imaging test for the screening, diagnosis, and monitoring of various cardiothoracic disorders. According to estimates, CXRs make up around 20% of all imaging exams, with millions of CXRs performed in the United States alone each year. Despite its widespread use, CXR interpretation is subjective and prone to wide interobserver inconsistencies. This can lead to missed findings, which can have serious implications, as 19% of early lung cancers that present as nodules on CXRs are missed. To address this issue, researchers from Massachusetts General Hospital and Harvard Medical School, Qure.ai, and CARPL conducted a study to evaluate the frequency of missed findings in CXRs and the potential of artificial intelligence (AI) to reduce missed findings.

Robotic surgery has many benefits, including faster recovery time, less scarring, less pain, and shorter hospital stays. These factors allow patients to resume normal life faster.The region's highly developed healthcare infrastructure is facilitating the integration of robotics into healthcare facilities, boosting the market for robotic surgery. The prevalence of chronic cardiovascular disease, fueled by rising obesity, is expanding the market opportunity. Some of the major advances expected over the next few years are high-definition cameras and battery-powered computing devices. AI and ML are likely to improve the accuracy and precision of robotic surgery, further improving the reliability of surgery and accelerating the growth of the robotic surgery market.

An artificial intelligence (AI) driven assessment tool for diagnosing mental health disorders has become the first mental health chatbot to secure a Class IIa UKCA (UK Conformity Assessed) medical device certification. Using machine learning, Limbic Access is designed to support patient self-referral through digital conversations that are incorporated into the psychological therapy pathway. The chatbot can classify common mental health disorders treated by NHS Talking Therapies (IAPTs) with an accuracy of 93%. The certification comes as NHS Improving Access to Psychological Therapies (IAPT) services are experiencing significant capacity challenges in the face of record demand. In 2021-22, 1.24 million referrals accessed IAPT services, compared to 1.02 million in 2020-21, an increase of 21.5%.
