Fossil fish tooth chemistry uncovers Southern Hemisphere role in Earth's ice age shift

To understand where Earth might be headed, it's important to know where it has been. Throughout its existence, especially over the past couple of million years, Earth has experienced periodic cold and warm intervals, known as glacial and interglacial periods.

Wastewater management reverses widespread freshwater deoxygenation in China

Freshwater ecosystems worldwide have been suffering from declining oxygen levels—a trend known as deoxygenation—that threatens biodiversity, fisheries and ecosystem stability. However, a new study published in Nature Geoscience offers hope: targeted nutrient management via wastew

Screen reveals new proteins that control RNA processing

Researchers at the University of California San Diego have developed a large-scale screening approach that identifies proteins controlling a fundamental step in gene expression known as alternative polyadenylation (APA). APA determines where an RNA molecule is cut and finished be

Chemically primitive galaxy from 13 billion years ago reveals record-low oxygen

An international team of astronomers has used the James Webb Space Telescope (JWST) and a natural phenomenon known as gravitational lensing to achieve a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago. Expanding upon initial detections, this

Novel crystal strategy delivers near-perfect zero thermal expansion from 11 K to 893 K

Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute challenge for extremely precise technologies, such as l

Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil stor

Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships between living organisms in the past, reconstruc

NASA tests new refuel device for future in-space refueling missions

For NASA's next generation of deep-space exploration missions, spacecraft may need to refuel in Earth orbit before pushing farther into the solar system. Similar to how a gas pump needs a nozzle to fit your fuel tank, future spacecraft could require a special device in order to f

Scientists say creatine may help fight depression

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 participants and found mixed results

Stop the sting! Fire ant control tips

Fire ants are a common nuisance across much of the United States, known for their painful stings and unsightly dirt mounds in lawns and outdoor spaces. However, for individuals who are allergic, these pests can cause potentially life-threatening reactions. To help keep communitie

One of the most distant 'leaky' galaxies ever found may reveal how the universe reionized

Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.
