  • AI tool uses face photos to estimate biological age and predict cancer outcomes

    AI tool uses face photos to estimate biological age and predict cancer outcomes

    Eyes may be the window to the soul, but a person’s biological age could be reflected in their facial characteristics. Investigators from Mass General Brigham developed a deep learning algorithm called FaceAge that uses a photo of a person’s face to predict biological age and survival outcomes for patients with cancer. They found that patients with cancer, on average, had a higher FaceAge than those without and appeared about five years older than their chronological age. Older FaceAge…

  • Ultra-Processed Foods Directly Linked to Poor Health

    Ultra-Processed Foods Directly Linked to Poor Health

    A new study published in the journal Nutrition & Metabolism has shown that consumption of ultra-processed foods is directly and significantly linked to poor health outcomes.

    The cross-sectional study used data from the Canadian Health Measures Survey from 2016 through 2019 that included nearly 6,000 participants. Data on dietary content was collected using a food frequency questionnaire, and participants were grouped into quartiles based on their intake…

    Healthy Sleep Duration Varies by Location and Culture

    New research published in the Proceedings of the National Academy of Sciences has shown that the amount of sleep required for positive health outcomes varies significantly between locations and cultures, challenging the common belief that all people need around the same amount of sleep.

    The study included sleep duration and health data from nearly 5,000 people in 20 different countries. Many previous studies have shown that shorter sleep durations are…

  • Rethinking The MD/MBA Pathway: Why Timing Matters

    Rethinking The MD/MBA Pathway: Why Timing Matters

    When I was a medical student, I was among the few who pursued and completed a joint MD/MBA degree. At the time, it felt pioneering. The combination of clinical and business education promised to equip us to address the deep inefficiencies and inequities of the American healthcare system—not just from the exam room, but also from the boardroom.

    Fast forward two decades, and MD/MBA programs have grown substantially in…

    Health care workers, firefighters have increased PFAS levels, study finds

    A study including researchers from the University of Arizona Health Sciences and published in the Journal of Exposure Science & Environmental Epidemiology found that firefighters had higher concentrations of certain per- and polyfluoroalkyl substances, or PFAS, and health care workers had moderate elevations of PFAS in their blood with significantly higher odds of two specific PFAS when compared with other essential workers.

    “Our study reinforces previous research showing elevated PFAS…

  • 3D printing in vivo using sound

    3D printing in vivo using sound

    Imagine if doctors could precisely print miniature capsules capable of delivering cells needed for tissue repair exactly where they are needed inside a beating heart. A team of scientists led by Caltech has taken a significant step toward that ultimate goal, having developed a method for 3D printing polymers at specific locations deep within living animals. The technique relies on sound for localization and has already been used to print polymer capsules for selective drug delivery as well…

  • Unique model of rare epileptic disease helps pinpoint potential treatment route

    Unique model of rare epileptic disease helps pinpoint potential treatment route

    While extremely rare, encephalopathy (a condition affecting brain function) triggered by mutations in the UBA5 gene has devastating impacts, with affected individuals reaching few developmental milestones and experiencing frequent and early-onset seizures. Scientists at St. Jude Children’s Research Hospital created a first-of-its-kind cortical organoid model for the disorder, studying how it causes developmental defects and identifying potential ways to treat it. The findings were published…

    Lab-on-a-chip devices take public health into home

    University of Cincinnati engineers created a new device to help doctors diagnose depression and anxiety.

    UC College of Engineering and Applied Science Distinguished Research Professor Chong Ahn and his students developed a “lab-on-a-chip” device that measures the stress hormone cortisol from a patient’s saliva. Knowing if a patient has elevated stress hormones can provide useful diagnostic information even if patients do not report feelings of anxiety, stress or depression in a standard…

  • New study traces sharp regional shifts in ischemic heart disease burden — a global warning signal

    New study traces sharp regional shifts in ischemic heart disease burden — a global warning signal

    A new study puts the spotlight on the rising burden of ischemic heart disease across Southeast Asia, East Asia and Oceania, and calls for localized, equity-focused interventions in these regions. The researchers identified region-specific, modifiable risk factors that influence the increasing prevalence of ischemic heart disease, such as toxic air pollution in East Asia and ultra-processed dietary dependence in Oceania. The study will be presented at the ACC Asia 2025 Together With SCS 36th…

  • Incidence rates of some cancer types have risen in people under age 50

    Incidence rates of some cancer types have risen in people under age 50

    Researchers at the National Institutes of Health (NIH) have completed a comprehensive analysis of cancer statistics for different age groups in the United States and found that from 2010 through 2019, the incidence of 14 cancer types increased among people under age 50. Of these cancer types, nine — including several common cancers, such as breast cancer and colorectal cancer — also increased in some groups of people aged 50 and older. However, the incidence of 19 other cancer types –…
