Phys.org / First evidence of lost-wax casting for silver in Bronze Age Western Europe uncovered
In a recent study, Dr. Linda Boutoille uncovered the first evidence of lost-wax casting of silver objects in Bronze Age Iberia and, to date, Western Europe. Published in the Oxford Journal of Archaeology, the study examines ...
Phys.org / KIC 5623923 is a faint eclipsing binary exhibiting Delta Scuti-type pulsations, observations find
Using NASA's Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary experiencing Delta Scuti-type ...
Phys.org / Degraded peatlands emit nearly twice as much greenhouse gas as previously thought, study finds
For the first time, researchers have produced a detailed, high-resolution map of peatlands in the EU, showing that these areas emit twice as much greenhouse gases than previously thought. The research, led by eco-hydrologist ...
Phys.org / Scientists rule out fourth neutrino in particle physics mystery
Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it.
Phys.org / Complex life developed nearly 1 billion years earlier than previously thought, study reveals
Complex life began to develop earlier, and over a longer span of time, than previously believed, a new study has revealed. The research sheds new light on the conditions needed for early organisms to evolve and challenges ...
Phys.org / Traditional note-taking beats AI chatbots for reading comprehension, but a combined approach is still useful
A new study suggests that traditional learning activities like making notes remain critical for students' reading comprehension and retention, while also suggesting that large language models (LLMs), such as ChatGPT or Microsoft ...
Phys.org / The bacteria that won't wake up: NASA discovers new bacteria 'playing dead'
New research conducted on a NASA-discovered bacterium shows the microbe is capable of entering an extreme dormant state, essentially "playing dead" to survive in some of the cleanest environments on Earth.
Phys.org / Simulations reveal how black holes generate intense light from infalling matter
Surprisingly, some of the universe's brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a team of computational ...
Phys.org / Precise catalyst design boosts hydrogen gas production efficiency and affordability
A recent advance in the science of hydrogen fuel production could enable higher output and more sustainable production of this renewable energy source, researchers with Stockholm's KTH Royal Institute of Technology report.
Phys.org / Bumble bees launch a three-stage defensive response when their nest is disturbed
Bumble bees respond to physical disturbance of their nest with a sequence of defensive behaviors that lasts up to 10 minutes, according to a study by Sajedeh Sarlak at the University of Konstanz, Germany, and colleagues.
Phys.org / Long-standing puzzle in electron scattering deepens with new measurement
Why does lead behave so differently from every other atomic nucleus when struck by electrons? A team of physicists at Johannes Gutenberg University Mainz (JGU) has taken an important step toward answering this question, only ...
Phys.org / Deciphering the heavyweights of the tetraquark world
The CMS collaboration reports the first measurement of the quantum properties of a family of tetraquarks that was recently discovered at the LHC.
