https://medicalxpress.com/ en-us provides the latest news from Stanford University Perhaps to the surprise of their creators, large language models have become confidants, therapists, and, for some, intimate partners to real human users. In a new study, AI researchers at Stanford studied verbatim transcripts of 19 real conversations between humans and chatbots to understand how these relationships arise, evolve, and, too often, devolve into troubling outcomes the researchers describe as "delusional spirals." https://techxplore.com/news/2026-04-ai-relationships-trigger-delusional-spirals.html Tue, 21 Apr 2026 11:00:10 EDT news695986862 Stanford researchers interviewed 21 global health leaders to identify specific strategies men can use to support women's career advancement. https://medicalxpress.com/news/2026-04-male-allies-key-women-global.html Fri, 17 Apr 2026 08:00:01 EDT news695627882 When Glenn Carroll talks to managers about the culture at their organization, about 80% of them say it needs to change. Yet they're often unsure how to influence culture, so they fall back on a small set of change mechanisms like aligning leaders around values and using culture-related training and communications. https://phys.org/news/2026-04-qa-great-company-culture-nice.html Wed, 15 Apr 2026 12:40:05 EDT news695470861 Latino-owned businesses in the U.S. continue to overcome funding challenges to pursue expansion and innovation—through strategies such as scaling internationally, acquisitions, and investing in artificial intelligence. Between 2017 and 2023, they grew at a faster rate than white-owned businesses overall—and in California and Florida, they accounted for more than 55% of all net new firms. https://phys.org/news/2026-04-latino-business-owners-growth-ai.html Wed, 15 Apr 2026 12:20:06 EDT news695470682 A new study by SIEPR's Michael Blank is among the first to examine an overlooked effect of generative AI: it's significantly boosting how much people get done at home. Barely a day goes by when there isn't a story about generative AI and what it means for companies and worker productivity. For good reason: the more artificial intelligence can perform job tasks independently, the more work can get done in less time. In theory, that's great for economic growth. https://techxplore.com/news/2026-04-ai-big-productivity-boost-sofa.html Wed, 15 Apr 2026 11:40:03 EDT news695471101 Light has an increasing number of applications in biology and medicine—it can be used to stimulate cell growth, manipulate neural signals, and treat some cancers—but it doesn't easily pass through tissue. Most methods to bring light deep within the body are invasive, requiring either tissue to be removed or an optical fiber to be inserted. https://phys.org/news/2026-04-ultrasound-body-path-treatments.html Mon, 13 Apr 2026 13:00:01 EDT news695300402 Researchers have developed a volcanic rock formula that cuts carbon emissions by 67%, potentially offering an affordable alternative to increasingly scarce cement additives. https://techxplore.com/news/2026-04-volcanic-formula-cement-emissions-thirds.html Thu, 09 Apr 2026 13:10:01 EDT news694957125 As warming temperatures spread dengue to new regions, Stanford researchers are using AI-powered drones to hunt down hidden mosquito breeding sites. Anyone who has left water standing in a wading pool or empty flower pot knows how quickly mosquitoes arrive. But these backyard nuisances can spawn serious diseases: dengue, chikungunya, and Zika are all transmitted by mosquitoes breeding in water that collects in shallow containers. https://medicalxpress.com/news/2026-04-drones-ai-flight-combat-mosquito.html Wed, 08 Apr 2026 11:20:02 EDT news694861202 A new map of a brain circuit specific to chronic pain suggests a promising route to treatment for the roughly 60 million Americans living with persistent pain, according to a study published in Nature. The study showed that silencing the specific cells that drive this circuit eased chronic pain while preserving acute pain responses—in other words, the body's ability to signal danger. https://medicalxpress.com/news/2026-04-newly-chronic-pain-circuit-pathways.html Wed, 01 Apr 2026 15:20:07 EDT news694272601 The Artemis II mission launches this week as a first step toward returning to the moon and reaching Mars.

It is a provocative topic in the scientific community and an important one to wrestle with as AI's capabilities grow. https://techxplore.com/news/2026-03-exploring-ai-role-scientific-peer.html Tue, 31 Mar 2026 10:10:01 EDT news694169330 A Stanford study shows that jail-based hepatitis C programs could cut new infections by nearly half among people who inject drugs, potentially providing a major boost to lagging U.S. efforts to meet national hepatitis C elimination goals. https://medicalxpress.com/news/2026-03-based-hepatitis-infections.html Mon, 30 Mar 2026 12:00:11 EDT news694089452 A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica. https://phys.org/news/2026-03-antarctic-sea-ice-growth-sudden.html Sat, 28 Mar 2026 07:00:01 EDT news693896147 Protein-maxxing—the social media-fueled trend of maximizing dietary protein at every opportunity—is showing no sign of slowing. That's in part because the federal government has weighed in with nutrition guidelines that emphasize the consumption of meat and dairy and an increase in the recommended dietary allowance of protein by 50% to 100% over the previous RDA. https://medicalxpress.com/news/2026-03-qa-protein.html Fri, 27 Mar 2026 11:00:05 EDT news693826141 In a new study published in Science, Stanford computer scientists showed that artificial intelligence large language models are overly agreeable, or sycophantic, when users solicit advice on interpersonal dilemmas. Even when users described harmful or illegal behavior, the models often affirmed their choices. https://techxplore.com/news/2026-03-ai-overly-affirms-users-personal.html Thu, 26 Mar 2026 14:00:18 EDT news693667021 The economic damage yet to come from carbon dioxide emitted decades ago far exceeds the harm it has wrought so far, according to a new Stanford University study. The research, published in Nature, puts a dollar value on the harm done to individual nations and the world by carbon dioxide emitted over time by countries and major companies. https://phys.org/news/2026-03-co8322-emissions-bigger-future-economic.html Wed, 25 Mar 2026 12:00:05 EDT news693648541 Jack Welch, the legendary General Electric CEO, was infamous for firing the bottom 10% of his workforce every year, without exception. The company's market cap rose substantially during Welch's tenure, but his "rank and yank" ritual was divisive. If you knew your job was always on the line, the logic went, you would push harder and generate results. Yet what did this approach do to the employees who had to constantly compete with each other to keep their jobs? https://phys.org/news/2026-03-cooperative-workplaces-boost-freedom.html Tue, 24 Mar 2026 14:40:08 EDT news693573181 What if AI could predict the next financial meltdown?

Consisting of amino acids strung together into peptide chains, these molecules perform much of the work inside living cells. While they execute life's most essential functions with apparent ease, decoding their precise sequence and structure has long been one of biology's hardest challenges. https://phys.org/news/2026-03-protein-sequencing-advance-insights-life.html Wed, 18 Mar 2026 06:00:03 EDT news692980021 Diseases historically absent from the United States have been showing up in Florida, Texas, California and other U.S. states in recent years. To understand why, look to Peru. That's where researchers from Stanford and other institutions analyzed the connection between a cyclone and a massive outbreak of dengue fever, a mosquito-borne viral disease that can cause fever, rash, and life-threatening symptoms like hemorrhage and shock. https://phys.org/news/2026-03-warmer-wetter-cyclone-weather-peru.html Tue, 17 Mar 2026 11:00:07 EDT news692867488 Geneticist Anne Brunet explores what aging really is, how lifestyle choices might influence longevity, and the promising frontiers of aging research. Aging is a process that affects us all. But how many of us can clearly define what happens in our bodies when we age? For an inevitable and universal experience, it's shockingly mysterious. https://medicalxpress.com/news/2026-03-science-aging-qa-geneticist.html Tue, 17 Mar 2026 08:10:08 EDT news692952962 Stanford Medicine pediatric hematologist Agnieszka Czechowicz, MD, Ph.D., has devoted her research career to improving treatments for rare blood disorders. She's an expert in Fanconi anemia, a genetic disease that interferes with DNA repair and blood cell production. By age 12, most people with the disease experience a life-threatening complication called bone marrow failure, in which the body's blood-cell factory stops functioning. https://medicalxpress.com/news/2026-03-prenatal-stem-cell-treatment-rare.html Fri, 13 Mar 2026 12:30:02 EDT news692613621 Surprise parties. Marriage proposals. Sports upsets. Bank collapses. Military sneak attacks. Why do some unexpected events catch us completely off guard while others don't? For years, political scientists, security analysts, and financial gurus have tried to understand how information can be used to forecast what comes next and, through post-mortems, diagnose why certain predictions fail. https://medicalxpress.com/news/2026-03-style-amplify.html Fri, 13 Mar 2026 10:20:07 EDT news692613317 By midlife, an animal's everyday behaviors can signal how long it is likely to live. That is the striking conclusion of a new study in which researchers put scores of short-lived fish under continuous, lifelong surveillance to explore how behavior and aging are linked. https://medicalxpress.com/news/2026-03-lifetime-motion-reveals-architecture-aging.html Thu, 12 Mar 2026 14:00:08 EDT news692522662 As tech giants race to power AI data centers and extreme weather becomes more frequent, America's electrical grid is straining under conditions it was not built to handle. Alice Hill, senior director for resilience policy on the National Security Council during the Obama administration, has a message for business leaders and policymakers: prepare now. https://techxplore.com/news/2026-03-qa-ai-era-america-energy.html Wed, 11 Mar 2026 17:20:07 EDT news692467861 The conversation around AI and art generally swings between two extremes: a flood of AI slop or the total automation of creative work. The more desirable approach may be an AI that behaves as a useful collaborator. But thus far, visual artists working with text-to-image tools confront frustrating basic hurdles in their abilities to direct AI. Ask an AI to create an image of a house? Not too difficult. Direct it to make the house red, with four front-facing windows, a chimney, and ivy covering the left side? Good luck. https://techxplore.com/news/2026-03-ai-artists-creative-ground.html Wed, 11 Mar 2026 11:50:01 EDT news692448397 A Stanford study shows simple digital prompts can motivate people taking GLP-1 medications to make lifestyle changes.
