A new analysis of Tyrannosaurus rex teeth indicates the predator maintained a body temperature of about 36.3°C, close to that of elephants and far warmer than cold-blooded reptiles.
Researchers have identified a population of cells that can initiate programmed cell death, survive the process, and then drive rapid tissue repair. Their descendants show increased resistance to future damage, …
A spotted wildcat in Bolivia has been confirmed as a new species, with only one living individual currently known to science. The discovery highlights the urgent need for further surveys …
A pocket-sized detector costing about $100, originally built as a student physics project, is now used in major experiments, balloon missions, and potentially future spacecraft to observe cosmic particles that …
A previously unrecognized fruit-eating pigeon from the genus Ducula has been documented on Tawi-Tawi in the Philippines' Sulu Archipelago, according to research led by the Delaware Museum of Nature & …
Genetic analysis confirms the Tilcayo, a small wild cat known to local communities for generations, is a species distinct from other tiger cats.
Genomic analysis of 38 Leopardus cats reveals Leopardus tilcayo, a new species from Bolivia's Yungas forests, marking the first scientific naming of a new cat species in 100 years.
Researchers have achieved real-time, molecular-resolution monitoring of individual virus-like particles as they self-assemble, using mass photometry combined with a single-molecule trapping method. The technique reveals assembly pathways and dynamics that …
Fossils unearthed in Egypt's Dakhla Oasis have led paleontologists to describe a previously unknown species of mosasaur, an extinct marine reptile that lived alongside dinosaurs during the Cretaceous period.
Chemical analysis of 66-million-year-old tooth enamel suggests Tyrannosaurus rex regulated its body temperature like modern birds and mammals, with a body temperature of about 36°C.
Steady-state photoluminescence alone can mask critical differences in optoelectronic materials, prompting researchers to combine time-resolved, spatially resolved, and spectrally resolved methods into unified characterization platforms.
Researchers in China and the US have demonstrated that vacuum fluctuations can enhance superconductivity in a bulk material, introducing a new concept called vacuumtronics that could lead to non-invasive control …
NOAA scientists have identified nine previously unknown sponge species in the Gulf of Alaska and the Aleutian Islands, raising Alaska's known sponge total to 232 as bottom trawling and planned …
Researchers studying ancient rocks from Western Australia propose that water-rich crust sank into Earth's mantle through a process called dripduction, helping generate magma and volcanic eruptions more than three billion …
Paleontologists have identified the first known footprints from an adult Tyrannosaurus rex, a 23-foot trackway in North Dakota's Hell Creek Formation dating to 66.5 million years ago.
Researchers have directly captured two negatively charged DNA molecules pairing up, with positively charged metal ions bridging the repulsion — a two-decade-old theory now confirmed, with implications for cancer research.
Researchers at Tokyo University of Science discover that non-reciprocal interactions between differently sized colloidal particles prevent aggregation and keep the system in a state of continuous reorganization, offering a new …
Dengyingia pennata, a newly described frond from South China, combines a distinctive branched body with features consistent with suspension feeding more than 540 million years ago.
Scientists synthesized CaSiC2O7 at 122 gigapascals and about 2,800 kelvin, revealing an unexpected chemical bridge between carbonates and silicates near core-mantle conditions.
High-pressure experiments produced dense hydrogen-bearing iron phases that could sink toward the core-mantle boundary, offering a possible long-term reservoir for deep-Earth water.
