A new study published in the Proceedings of the National Academy of Sciences demonstrates how radiocarbon dating can reveal the maximum lifespan of Mediterranean hardwoods, uncovering hidden links between human history and long-term ecosystem dynamics. By analyzing mature and ancient oak trees across Italy, researchers found that a millennium of age is attainable from the Mediterranean coast to mountain environments.
Having Black teachers and other educators of color improves students' classroom experiences, research shows. They often serve as role models, set high academic expectations and teach material that connects to students' lives outside of schools.
Thousands of small earthquakes, detected for the first time by a machine-learning process, reveal the distinct, razor-sharp edge of the Yakutat microplate as it subducts beneath the North American plate.
Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. The results, published in the journal Nature Plants, show how a crucial protein interaction at the interface between photosystems I and II controls the photosynthetic machinery.
Imagine a train parked at the station. Passengers climb aboard and find their seats. Conductors move up and down the aisles, checking tickets. But there's a problem—the engineer's watch is broken. As a result, the doors never close, the whistle never sounds, and the train never starts. Something similar occurs in cells when developmental timing is disrupted. Rather than making people late for work, it can mean the difference between maturing into a healthy adult and never growing up at all.
Computational point-of-care sensors can significantly improve access to diagnostics by enabling rapid patient testing outside centralized medical facilities. These tests rely on machine learning models to make diagnostic predictions, but such inference models are susceptible to hallucinations and may produce erroneous outcomes. As a result, their limited reliability has partially hindered the broader adoption of computational sensors in health care settings.

For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.
New research suggests the fuzzy insects may be capable of spontaneously solving problems the way animals with much larger brains do.
Researchers have finally resolved a key problem in a 100-year-old theory of color, showing that the qualities we perceive in colors are intrinsic to the mathematics of color space itself. The discovery sharpens our understanding of human vision and could lead to more precise color technologies and visualizations.
Homing pigeons rely on a variety of signals to navigate, including magnetism. But it hasn't been clear how they detect magnetic cues. Researchers propose the answer may be found in the birds' livers.
Scientists are building autonomous robotic labs powered by artificial intelligence. The goal, they say, is for these robots to take over human researchers' most laborious, time-consuming tasks.
NPR's Eyder Peralta speaks with immunologist Nicole Baumgarth about why ticks are spreading to new regions, and what this increase in ticks could mean for the spread of Lyme disease.
A specific pattern of brain metabolism visualized with PET imaging can predict which patients are most likely to benefit from Alzheimer's disease therapy. In a retrospective study of patients who received Alzheimer's treatments, those with the identified pattern experienced stabilized cognitive performance, while patients with other patterns had significant cognitive decline. This study was presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2026 Annual Meeting, where it r
A new doctoral thesis from Karolinska Institutet shows that the balance system can be assessed during the first months of life. Using new, child-friendly methods, health care services can detect vestibular dysfunction in children with hearing impairment at an earlier stage and offer targeted habilitation.
University of Cincinnati and Ohio State University researchers have found that adults with developmental disabilities who have integrated care were less likely to go to the emergency room or be hospitalized than those who did not.
Chromosomal instability is a common feature in many solid tumors and is associated with greater aggressiveness. For years, its main contribution to cancer was thought to be driving the evolution of tumor genomes, causing cells to gain chromosomes with growth-promoting genes or lose chromosomes with tumor-suppressor genes.
A research team has developed technology that uses artificial intelligence to analyze electroencephalogram signals triggered by thermal stimuli and objectively classify pain intensity. The study is published in IEEE Transactions on Neural Systems and Rehabilitation Engineering.
For a long time, the likelihood of surviving pancreatic cancer has been extremely low. For patients who were diagnosed with metastatic pancreatic cancer between 2015 and 2021, about 97% died within five years of their diagnosis.
Infections should be considered a "health hazard" in people living with diabetes, with experts warning that current clinical guidelines fail to reflect a substantial but underrecognized burden of illness, hospitalization and death. This is according to a major study published today in Diabetes and presented at the American Diabetes Association Scientific Sessions conference in New Orleans.
A novel PET radiotracer can accurately detect deep vein thrombosis in the legs and reveal whether clots have migrated to the lungs. By enabling whole-body imaging of blood clots in a single scan, the approach may support faster and more efficient diagnosis—particularly for patients who also require evaluation for potentially life-threatening pulmonary embolism. This research was presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2026 Annual Meeting, and the collection of
