Reconstructing precise clinical timelines is essential for modeling patient trajectories and forecasting risk in complex, heterogeneous conditions like sepsis. While unstructured clinical narratives offer semantically rich and contextually complete descriptions of a patient's course, they often lack temporal precision and contain ambiguous event timing. Conversely, structured electronic health record (EHR) data provides precise temporal anchors but misses a substantial portion of clinically meaningful events. We introduce a retrieval-augmented multimodal alignment framework that bridges this gap to improve the temporal precision of absolute clinical timelines extracted from text. Our approach formulates timeline reconstruction as a graph-based multistep process: it first extracts central anchor events from narratives to build an initial temporal scaffold, places non-central events relative to this backbone, and then calibrates the timeline using retrieved structured EHR rows as external temporal evidence. Evaluated using instruction-tuned large language models on the i2m4 benchmark spanning MIMIC-III and MIMIC-IV, our multimodal pipeline consistently improves absolute timestamp accuracy (AULTC) and improves temporal concordance across nearly all evaluated models over unimodal text-only reconstruction, without compromising event match rates. Furthermore, our empirical gap analysis reveals that 34.8% of text-derived events are entirely absent from tabular records, demonstrating that aligning these modalities can produce a more temporally faithful and clinically informative reconstruction of patient trajectories than either source alone.

Nine-person jury to consider whether AI firm bilked world's richest person and unjustly enriched themselves Closing arguments began on Thursday in Elon Musk's lawsuit against Sam Altman and OpenAI, bringing the weeks-long courtroom battle between the two tech moguls nearer to a decision.

Closing arguments begin in Elon Musk's landmark lawsuit against OpenAI Lawyers for OpenAI and Elon Musk began closing arguments in a landmark trial that could impact the future of the ChatGPT maker. On Thursday, each side presented a concluding statement to jurors, who will decide whether OpenAI and its leaders profited from a venture that was meant to be a "charity". Musk sued OpenAI, its CEO Sam Altman and its president Greg Brockman, alleging that the company strayed from its founding mission to build AI that was safe and beneficial to humanity. Musk was not present for the closing statements on Thursday, as he is currently in China on a diplomatic visit with United States President Donald Trump. His lawyer, Steven Molo, used his final remarks to accuse OpenAI of breaching its charitable trust by enriching investors and insiders at the nonprofit's expense.

Elon Musk's team seems to have one main goal: make the OpenAI boss look like a liar. Musk's wins so far mainly involve making OpenAI and Altman look ridiculous. Get your news from a source that's not owned and controlled by oligarchs. Can you trust Sam Altman? That was one of the central themes at the high-profile trial between the OpenAI CEO and Elon Musk in California this week, as Musk's lawyers peppered Altman with questions on his work relationships, including his temporary ouster from OpenAI three years ago by a mistrustful board of directors .

Since debuting last spring, OpenAI's Codex coding app has seen standalone Mac and Windows releases, so it was only a matter of time before OpenAI gave people a way to access their Codex projects on mobile. Starting today, all ChatGPT users, including those using the chatbot through OpenAI's Go and Free tiers, can use the software through the ChatGPT app on Android and iOS. To be clear, you won't be using Codex to program on your phone. Instead, the ChatGPT mobile app is acting here as a intermediary between you and whatever environment you've set it up for your coding projects, whether that be a physical device like a Mac mini or a remote space managed by your company. That might seem limiting, but it does mean your files, credentials and permissions stay secure on the machine where Codex is running.

Today on, we discuss how Donald Trump's visit to China could influence conversations between world leaders at a moment when the economic and foreign policy stakes couldn't be higher. This week on, the team dives into Trump's selected entourage for his high-stakes visit to China, ranging from Silicon Valley's tech billionaires to director Brett Ratner. We also break down the latest developments in Elon Musk's lawsuit against Sam Altman, alleging that OpenAI abandoned its original nonprofit mission for profit-driven goals, and whether either side is actually gaining an edge in the trial.

He's accompanied by a select number of Silicon Valley's top CEOs. We'll discuss how their presence could influence conversations between world leaders at a moment when the economic and foreign policy stakes could not be higher for the US. A lot of them have been recycling very similar conspiracy theories from the Covid-19 pandemic . We're going to tell you what they're sharing and also how to spot this kind of harmful misinformation.

OpenAI's ChatGPT app for Mac just experienced a security breach involving two employee devices, according to a report by . The company is issuing a software update to users that's rolling out now, but won't arrive for everyone until June 12. The why of it all is a bit convoluted, stemming from a security issue involving open-source code. A widely-used open-source library was compromised and two devices at the company were impacted. Upon identification of the malicious activity, we worked quickly to investigate, contain and take steps to protect our systems, the company wrote in a blog post.

In this piece, we reflect on AIES 2025, and outline the conversations and presentations from a discussion session on LLMs in the context of clinical usage and human rights. This is a crosspost from the latest issue of AI Matters, published by the ACM SIAGI. This year's conference on artificial intelligence, ethics and society (AIES) took place in the north of Madrid within the 180m-high tower block that forms the vertical campus of IE University. The event kicked off with a welcome from the chairs and organising committee members, with this opening session also featuring the conference best paper awards. Topics covered during the three-day event included mitigating bias, integrating AI into the workplace, evaluating LLMs in clinical settings, power dynamics in AI ecosystems, and dataset creation.

'If OpenAI lost its footing as the AI industry frontrunner, another barely distinguishable competitor - Musk's xAI or other - would simply replace it.' 'If OpenAI lost its footing as the AI industry frontrunner, another barely distinguishable competitor - Musk's xAI or other - would simply replace it.' If it wasn't already clear, Elon Musk and Sam Altman hate each other. While the two men were once cofounders of OpenAI, they're now locked in a vicious feud, playing out in all its theatrics in front of a judge and jury in a California courtroom. Musk is suing, alleging that Altman and OpenAI president Greg Brockman tricked him into forming and funding the organization as a non-profit before they subsequently restructured it to have a for-profit entity.
