Phys.org / A very strong El Niño is approaching. Here's what we can expect
El Niño is a recurring climate event with impacts across the globe. It has three phases: one cold (known as La Niña), one neutral, and one warm (El Niño).
Phys.org / World's largest scorpion revealed by 415-million-year-old fossils
Fossil fragments found in the U.K. have been identified as remains of the largest scorpions ever. Measuring more than a meter in length, Praearcturus gigas was among the first large predators to ever stalk the land.
Phys.org / Genetically modified hookworms produce and deliver therapeutics
Hookworms, intestinal parasites that infect hundreds of millions of people in under-resourced tropical regions around the globe, have evolved to survive inside the human gut for years, secreting molecules that enable coexistence ...
Phys.org / Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV
An international team of astronomers have employed one of the Large-Sized Telescopes (LSTs) at the Cherenkov Telescope Array Observatory (CTAO) to observe a distant blazar known as OP 313. Results of the observational campaign, ...
Phys.org / Deep-Earth seismic anomalies may be explained by newly discovered manganese compound
Scientists know that manganese, in its various oxide forms, plays a significant role in Earth's geochemical cycles. However, the exact forms of manganese, their abundance and the mechanisms behind these cycles that occur ...
Phys.org / Giant fan-shaped structure found under East Antarctica
An international team of researchers including our Department of Geography has discovered a vast geological structure hidden beneath the East Antarctic Ice Sheet. The findings are published in the journal Nature Geoscience.
Phys.org / Dogs respond to human tone without words, hinting at communication older than language
Humans can communicate various instructions to dogs without using actual words—simply by modulating the tone of their voice, a new study from ELTE University's Department of Ethology shows. By repeating the nonsense syllable ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
Phys.org / Japan's new seafloor record could sharpen megathrust earthquake warnings in Nankai Trough
Off the southern coast of Japan, the Philippine Sea Plate lies underneath the Japanese mainland. The locked tectonic plates threaten to unleash a catastrophic megathrust earthquake, likely within the next few decades. Given ...
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory ...
Phys.org / How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution ...
