  • Acute chromatin decompaction stiffens the nucleus as revealed by nanopillar-induced nuclear deformation in cells
    Proceedings of the National Academy of Sciences, Volume 122, Issue 19, May 2025. <br/>SignificanceMany cellular processes such as wound healing, immune activation, and DNA damage repair require a temporally decompact and accessible chromatin structure. Whether such short-term remodeling of the chromatin impacts nucleus mechanics and ...... Read more »
  • The developmental factor TBX3 engages with the Wnt/β-catenin transcriptional complex in colorectal cancer to regulate metastasis genes
    Proceedings of the National Academy of Sciences, Volume 122, Issue 19, May 2025. <br/>SignificanceDysregulated Wnt signaling is a well-established driver of colorectal carcinogenesis. However, its pivotal role in normal intestinal stem cell homeostasis has posed significant challenges for its therapeutic inhibition, highlighting the need ...... Read more »
  • Blocking C-terminal processing of KRAS4b via a direct covalent attack on the CaaX-box cysteine
    Proceedings of the National Academy of Sciences, Volume 122, Issue 19, May 2025. <br/>SignificanceThe development of small molecule KRAS inhibitors has proven to be a challenge. Recent clinical development of covalent KRAS G12C inhibitors demonstrates the potential of targeting KRAS oncogenic proteins directly. Compounds that target the ...... Read more »
  • OGG1S326C variant frequent in human populations facilitates inflammatory responses due to its extended interaction with DNA substrate
    Proceedings of the National Academy of Sciences, Volume 122, Issue 19, May 2025. <br/>SignificanceOGG1S326C, a variant widely recognized as a risk factor for various malignancies and other diseases, has drawn significant attention due to its high prevalence (~20% in Caucasians and ~40 to 60% in Asians) in human populations. Despite... Read more »
  • Social dominance in rats is a determinant of susceptibility to stress
    Proceedings of the National Academy of Sciences, Volume 122, Issue 19, May 2025. <br/>SignificanceAlthough stress has significant impact on brain and behavior, its effects vary between individuals. Relatively little is known about how social status contributes to individual differences in stress vulnerability. We report that stress affects ...... Read more »
  • Architecture of Pseudomonas aeruginosa glutamyl-tRNA synthetase defines a subfamily of dimeric class Ib aminoacyl-tRNA synthetases
    Proceedings of the National Academy of Sciences, Volume 122, Issue 19, May 2025. <br/>SignificancePseudomonas aeruginosais a common cause of hospital-related infections and a formidable health threat due to its evolving antibiotic resistance.PaGluRS is homologous to other bacterial GluRSs in its domain architecture, but has evolved a ......

  • The Winter Vitamin D Crash – And the Workout That Prevents It
    New research shows that staying active in winter doesn’t just keep you fit—it also protects your vitamin D levels. The sun might be shining now, giving our vitamin D levels a natural boost, but not long ago we were in the depths of winter. During those colder, darker months, sunlight... Read more »
  • Is Your Salt Habit Secretly Fueling Depression?
    Too much salt doesn’t just affect your heart—it may also impact your mood. Scientists discovered that high-salt diets in mice led to depression-like behavior through immune system activity. Cutting out certain immune cells reversed the symptoms, pointing to new ways we might treat or even prevent depression. High-Salt Diet Linked... Read more »
  • One-and-Done Cure: New Gel Wipes Out Ear Infections in 24 Hours
    Scientists may have just found a game-changer for kids plagued by ear infections. A single squirt of a special gel cured the infection in animals within just 24 hours—no pills, no repeated doses. The gel slips through the eardrum to deliver medicine right where it’s needed, and it worked perfectly... Read more »
  • Quantum Speed Hack: Extra Qubits Slash Measurement Time Without Losing Precision
    Quantum scientists have cracked a longstanding problem by devising a method to speed up measurements without losing accuracy, a key hurdle for quantum technology. By cleverly adding extra qubits, they traded “space” for time, gathering more information faster without destabilizing the fragile quantum systems. This innovative approach, involving top researchers... Read more »
  • Quarks Gone Rogue: Flavor Symmetry Break Sparks Physics Shake-Up at CERN
    In high-energy collisions between argon and scandium atomic nuclei, scientists from the international NA61/SHINE experiment have uncovered a striking anomaly. It points to a possible breakdown of one of the most fundamental principles in particle physics: the near-symmetry between up and down quarks, known as flavor symmetry. This unexpected result...

  • Quantum Computers Just Outsmarted Supercomputers – Here’s What They Solved
    USC researchers have achieved a milestone in quantum computing by showing that quantum annealing can solve complex optimization problems faster than classical methods. With advanced error correction, they beat top classical algorithms using a D-Wave quantum processor. Quantum Advantage Demonstrated In a major breakthrough, researchers at USC have shown that...

  • Bats Learn To Hunt by Eavesdropping on Mating Calls, Study Reveals
    Data collected on juvenile and adult fringe-lipped bats provide the first insights into how eavesdropping behavior develops in these predators. Scientists at the Smithsonian Tropical Research Institute (STRI) have discovered that fringe-lipped bats, which locate their prey by eavesdropping on frog and toad mating calls, learn to tell the difference...

  • Inflammation Tied to Motivation Loss in Schizophrenia
    A new study has uncovered a biological link between inflammation and motivational deficits in people with schizophrenia, identifying a promising treatment target for symptoms that current medications fail to address. Higher levels of the inflammatory marker C-reactive protein were associated with reduced activity in brain regions involved in reward and... Read more »
  • Your Brain Loves Deep Breathing, Science Explains Why
    Breathwork, or the practice of intentionally controlling one’s breathing, has been shown to calm brain activity, reduce anxiety, and even ease symptoms of depression. Deep, slow breathing engages neural circuits that regulate emotional states, producing a measurable calming effect.... Read more »
  • Midlife Cortisol Levels Linked to Alzheimer’s Risk
    A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who... Read more »
  • Babies Fight COVID Differently Than Anyone Else
    Infants hospitalized with severe COVID-19 mount an immune response that looks entirely different from that of adults or older children. Researchers found both interferon responses and inflammation were elevated simultaneously—something never before observed in other viral infections.... Read more »
  • AI Chatbots Mirror a Human Brain Disorder
    Researchers have found a surprising similarity between the way large language models (LLMs) like ChatGPT process information and how the brains of people with Wernicke’s aphasia function. In both cases, fluent but often incoherent output is produced, suggesting rigid internal processing patterns that can distort meaning.... Read more »
  • Tylenol Targets Pain Through Unexpected Endocannabinoid Pathway
    A new study reveals that acetaminophen (Tylenol) relieves pain by reducing levels of an endocannabinoid called 2-AG, rather than increasing it as previously thought. This discovery challenges decades-old assumptions about how pain relief works and may open the door to designing safer, more targeted medications.... Read more »
  • Calm Your Mind: Choose Mindfulness by Anxiety Type
    Mindfulness is well known for its calming effects, but researchers now propose that different types of mindfulness practices may be more effective for specific types of anxiety.
