Phys.org / 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.
Phys.org / New research reveals the motivations and tactics used by call center fraudsters
A new study led by the University of Portsmouth lifts the lid on the tactics used by call center fraudsters in India, while revealing the shocking scale of the industry within the country. Published in the Journal of White ...
Phys.org / An iconic spear-throwing device likely wasn't used by prehistoric hunters until around 10,000 years ago
Archaeologists have long pictured prehistoric hunters taking down mammoths and other megafauna using the atlatl, a handheld spear-throwing device that uses leverage to achieve greater velocity and force when throwing darts. ...
Phys.org / The invasive fern that science misidentified for decades
Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present ...
Phys.org / Tiny ancient fish fossil with preserved brain offers clues to early fish evolution
Over 300 million years ago, a minnow-sized fish died and fell to the bottom of a prehistoric swamp near the village of Trawden, Lancashire, in northwest England. The remains of this tiny fish—known as Trawdenia planti—became ...
Phys.org / Arabian Sea sediments reveal summer and winter monsoons shifted differently after last ice age
High-resolution sediment analyses from the Arabian Sea reveal, for the first time, that summer and winter monsoons respond differently to global climate change. The study enhances understanding of past precipitation patterns ...
Phys.org / The largest digital camera ever built begins decade-long survey of the universe
The largest digital camera ever built is starting to capture images of unseen corners of the universe.
Phys.org / Houston power plant emerges as dominant source of cloud-forming aerosols
Research by atmospheric scientists at UC San Diego's Scripps Institution of Oceanography and colleagues pinpointed an individual coal-fired power plant in Houston as the main source of particles most likely to encourage the ...
Phys.org / Open cluster NGC 6134 in Norma is 1.38 billion years old and hosts a core, tidal tail and diffuse halo
Indonesian astronomers have conducted a comprehensive study of an open cluster in the constellation Norma, known as NGC 6134. Results of the new study, available in a research paper published June 23 on the preprint server ...
Phys.org / World Cup research reveals strategy to give teams a penalty-shootout edge
One of football's most iconic moments—the penalty shootout—may be far more strategic than previously thought, with new research challenging the notion that the team kicking first holds a major advantage.
Phys.org / Human activity has not always harmed biodiversity—quite the opposite
For millennia, farming in Switzerland did not reduce plant diversity but helped increase it, University of Basel researchers have shown in a detailed reconstruction covering the past 7,000 years. Only recent decades paint ...
Phys.org / The little red galaxies that may be sending us neutrinos
Peering far into the distant, high-redshift universe, the James Webb telescope has discovered an abundance of small red galaxies known as the Little Red Dots. From their observations, astronomers believe that at least some ...
