Perplexity has announced a partnership with PayPal to bring conversational commerce to life within its Perplexity Pro platform. Launching this summer in the U.S., this collaboration allows users to shop, book travel, and secure tickets instantly with PayPal or Venmo—all through Perplexity’s chat interface. Aravind Srinivas, CEO of Perplexity, emphasizes the shared focus on trust, while PayPal CEO Alex Chriss highlights the ease and security of shopping during chats. Key features include seamless payment, shipping coordination, tracking, and passkey-powered checkouts. This innovation also taps into PayPal’s global network of over 430 million accounts across 200 markets, all backed by strong security protocols.

Philips and Nvidia are working together to develop AI-driven advancements for MRI systems. The partnership focuses on creating a new AI model designed to improve the quality of MR images, reduce scanning times, and support more accurate diagnoses. Radiologists may find tools such as interactive image adjustments and automated scanning processes particularly relevant for enhancing workflow efficiency. This collaboration highlights ongoing efforts to modernize medical imaging and demonstrates how AI continues to play an important role in healthcare technology.

Apple is investigating the integration of AI-driven search functionality into its Safari browser, a move that could shake Google's dominance in online search. Eddy Cue, an Apple executive, revealed this potential shift during testimony in Google's antitrust trial with the U.S. Department of Justice. Analysts estimate that Google pays Apple roughly $20 billion annually to remain Safari’s default search engine, a lucrative arrangement now under scrutiny. With Apple’s ecosystem spanning 2.5 billion devices, any changes in search priorities could reshape the industry. Cue pointed to rising user interest in AI platforms like OpenAI and Perplexity, hinting at their future inclusion in Safari. Google’s ad business might face major repercussions.

Artificial intelligence is quickly shifting from an emerging trend to a foundational tool in the real estate industry. According to T3 Sixty’s latest Tech 200 list, more than half of the featured products now integrate AI, a notable rise from just under a third last year. Brokers and agents are adopting AI for tasks like lead management, content creation, and market analysis. Industry leaders are warming to the widespread use, with only 42% expressing significant concern — down from 50% a year ago. Alongside AI adoption, consolidation is reshaping the sector, with key acquisitions occurring among tech firms. Despite mergers, fresh innovators are making their mark, while established players dominate the landscape.

Groundbreaking research led by Yong Chen at the University of Pennsylvania's Perelman School of Medicine could revolutionize mental health diagnosis and treatment. Chen's work focuses on artificial intelligence that could detect mental health conditions — like dementia and depression — years before they fully manifest. Incorporating biometrics, psychometric testing, and smart-device data, the AI aims to revolutionize early diagnoses and personalized treatments. While still in the research phase, actionable insights are expected within two years, facing challenges such as privacy concerns and data variability. These tools promise to reshape mental health care, yet regulatory and technical hurdles remain.

Researchers from the University of Rochester and other institutions have developed MagicTime, an AI text-to-video model that generates realistic metamorphic videos. The system learns from time-lapse footage to simulate complex processes like plant growth or construction. MagicTime produces short, high-resolution clips that more accurately depict physical, chemical, and biological changes compared to previous models. This advancement moves AI closer to effectively modeling real-world transformations. The technology could potentially aid scientists in preliminary research by allowing faster exploration of ideas before conducting physical experiments.

Artificial Intelligence is improving at identifying locations based on minimal details – from photos to sounds. Tools like ChatGPT and Perplexity analyze visual elements, such as architecture, landscapes, and even tool brands, to pinpoint places. Remarkably, AI can also draw conclusions from audio data, such as bird songs, narrowing down locations based on species habitats. For example, a Dutch-made wheelbarrow or migratory bird song range were enough for the AI to deduce general locations in tests. These revelations highlight privacy concerns in an age of AI-driven geo-guessing. As social media content fuels AI accuracy, users may unintentionally share their whereabouts.

Google is seeing a rise in visits, but users are spending less time on the site. A recent analysis reveals this trend through data from 5 billion search queries and 20 million websites. Since the introduction of AI Overviews in May 2024, U.S. visits to Google have increased by 9%. However, user engagement, including time on site and pages per visit, is either flat or declining across the U.S., UK, and Germany. Despite slightly longer search queries, the new user pattern suggests people visit Google frequently and leave quickly after finding answers. These findings, impacting SEOs and brands, emphasize the need to adapt to changing user behaviors.

OpenAI's recent update to GPT-4o in ChatGPT led to unexpected sycophantic behavior. Launched on April 25 and rolled back on April 28, the update made the model unnervingly eager to please, affecting user interactions. Users experienced the model validating doubts, fueling anger, and reinforcing negative emotions. Despite positive offline evaluations and AB tests, the sycophantic trend went unnoticed during reviews. OpenAI has since addressed the issue, opting for an earlier version of GPT-4o with more balanced responses.

Google's latest experiments through its Labs platform introduce three innovative tools — Tiny Lesson, Slang Hang, and Word Cam — that use Generative AI to support language learning in novel ways. Tiny Lesson offers personalized guidance on key phrases and grammar based on scenarios like grocery shopping. Slang Hang generates dynamic dialogues, allowing users to explore dialects and conversational patterns. Word Cam utilizes image recognition, helping learners identify and translate objects in real time through photos. Powered by the advanced Gemini AI, these initiatives aim to present fresh methods for language education.
