Looking Sideways Without the Blur Most cameras still pretend the world is flat. Lenses bend light onto a rigid chip, edges smear, corners go soft, and engineers pile on corrective glass until the whole package swells. Nature never bothered with that workaround. Our own retinas cup the light. A fish eye cups it even more boldly. A team at the Hong Kong University of Science and Technology has now given that curved strategy the pixel density it has long lacked.

A thermometer you can swallow Core body temperature is one of medicine’s quietest storytellers. A gentle dip can flag early infection. A local cool-down can whisper that blood flow has stalled. Fertility cycles, gut inflammation, heat stress in athletes—temperature carries the plot. The catch has always been how we listen. Rectal and oral probes are invasive and wired. Existing swallowable capsules work, but they are relatively large—often the size of a small vitamin you wouldn’t want stuck anywhere.

A Living Web Beneath Our Feet Scoop up a teaspoon of healthy soil and you might be holding something astonishing: as much as ten meters of delicate fungal thread, quietly trading with plant roots. Scale that up, and the picture becomes almost cosmic. An international team has now produced the first global maps of arbuscular mycorrhizal fungal networks—the underground partnerships that link fungi to roughly 70 percent of plant species on Earth.

Watching Electricity Race Through a Living Brain Imagine trying to listen to every conversation in a crowded stadium at once—and catching not just the cheers, but the exact instant each person starts speaking. That is roughly the challenge neuroscientists face when they want to understand how brains work as whole systems. Calcium imaging has long let researchers watch activity ripple across tiny vertebrate brains, yet calcium is a slow proxy.

DinoTracker Now, researchers and dinosaur enthusiasts alike can upload an image or sketch of a dinosaur footprint from their mobile phone to the DinoTracker app and receive an instant analysis. Fossilised dinosaur footprints are an important indicator of pre-historic life but previous research has shown that they are notoriously difficult to interpret.

Unveiling Hidden Pathways in Water's High-Pressure Transformations New research from Korea Research Institute of Standards and Science (KRISS) suggests that water, under extreme pressure at room temperature, can follow multiple freezing and melting pathways through a newly identified metastable ice phase called ice XXI.

Brain Connectivity Predicts Function Across the Entire Human Brain New research from Ohio State University suggests that patterns of connectivity between brain regions can reliably predict their specialized functions, offering a broad perspective on how the brain organizes cognition. This study, conducted by scientists at The Ohio State University, extends previous findings by examining the link across 33 cognitive processes, from sensory perception to executive decision-making.

Unlocking the Mystery of Induced Earthquakes on Stable Faults New research conducted by Utrecht University suggests that faults traditionally viewed as stable—those that strengthen as they slip—can still trigger earthquakes when disturbed by human activities. Published in Nature Communications, the study offers promising insights into why these events occur in tectonically quiet regions, potentially improving seismic hazard assessments for subsurface energy projects.

Boron arsenide has dethroned diamond as the best heat conductor University of Houston researchers have made a groundbreaking discovery in thermal conductivity, overturning an existing theory that boron arsenide (BAs) couldn’t compete with the heat conduction of a diamond.
