Phys.org / Tyrannosaurus rex teeth reveal a body temperature close to the human average
When picturing a scaled, toothy Tyrannosaurus rex stomping across North America, building nests and eating other dinosaurs, it's easy to forget that scientists have gleaned everything we know about T. rex from clues left ...
Tech Xplore / Manuscripts-turned AI agents can now 'talk' to each other and make new discoveries
Since 1665, scholarly journals have served as written records of scientific advancement—static words on a page, references written by people for other people to read. That's about to change.
Phys.org / Nullarbor mapping reveals surface signs of deep, hidden cave systems
Mysterious trenches stretching for kilometers across southern Australia's Nullarbor Plain have been revealed as the surface footprints of deep, hidden ancient cave systems.
Phys.org / Newfound fungal nutrient-sensing mechanism could advance biofuels and disease control
Scientists have taken a step toward a better understanding of how fungi sense and respond to nutrients in the environment, which is critical for engineering fungi for green technologies and combating fungal pathogens and ...
Phys.org / Black holes from stellar to supermassive size may follow one jet-launching rule
An early-career Western Australian astrophysicist has helped uncover a universal rule behind one of the most powerful behaviors in the universe: when black holes launch jets. The discovery, published in the journal Nature ...
Phys.org / NASA spacecraft discovers a huge new crater on the moon
Scientists have discovered a crater on the moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected.
Medical Xpress / Stable frontal signals, flexible hippocampal ones: How the brain preserves context as goals change
While humans are completing a task, they can temporarily store information in their minds while also manipulating and adapting it based on changing circumstances. To support this capability, known as working memory, the brain ...
Medical Xpress / REM and deep sleep, not just total sleep time, associated with disease risk
Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases, and less than 5 hours of total sleep was associated with high disease risks, according to a new study published Sept. 17 in the ...
Phys.org / Astronomy's decades-long quest to understand cosmic topology
If some aspects of cosmic topology turn out to be true, the idea that starships might voyage across the cosmos for hundreds of thousands of light-years without ever returning to the same neck of spacetime could be problematic.
Phys.org / How accurately can we measure the ocean's deepest point?
How deep is the deepest ocean—and how precisely can we actually measure it? A Japanese research team led by the National Institute of Polar Research (NIPR), SOKENDAI, the University of Tokyo and other Japanese institutions ...
Phys.org / Weeping whales: Stillborn humpback whale grieving documented
Humpback whale mothers may experience grief when their calves die, a rare research observation led by Griffith University and Sea World Foundation has found.
Phys.org / Portable metasurface biosensor turns molecular signals into images, bypassing spectrometers
What if signs of disease could be detected using nothing more than a tiny chip that fits in the palm of your hand and a camera, without ever visiting a hospital? A scene that once seemed possible only in science fiction has ...
