Phys.org / Solar energy transforms polystyrene waste into valuable chemicals using sulfur
Turning waste into wealth may no longer be just a marketing slogan, as a team of researchers in China has found an eco-friendly way to do exactly that. The abundant sunlight our planet receives was put to use for transforming ...
Phys.org / Ultrathin BiFeO₃ breaks the 30 nm limit, delivering fourfold stronger piezoelectricity
Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric materials, such as lead ...
Phys.org / Proof-of-concept quantum battery shows faster charging as it gets larger
Australian scientists have made a significant leap forward in energy storage technology with the world's first proof-of-concept quantum battery. Similar to conventional batteries, this quantum version charges, stores and ...
Phys.org / Scientists discover new heavy proton-like particle at CERN
Scientists from the University of Manchester have played a leading role in the discovery of a new subatomic particle at CERN's Large Hadron Collider (LHC). The particle, known as the Ξcc⁺ (Xi‑cc‑plus), is a new type ...
Tech Xplore / AI chatbots' tendency to always agree may reinforce delusions in vulnerable users
The integration of large language model-based AI chatbots into multiple facets of our everyday lives has opened us up to advantages that would have been considered impossible even a decade ago. The same development has, however, ...
Phys.org / Bow and arrow arrived about 1,400 years ago across western North America, study finds
A study clarifies the date of an important technological milestone: the adoption of the bow and arrow in western North America. The replacement of older weapons by bows and arrows occurred independently in several prehistoric ...
Phys.org / Past intensive whaling threatens the future of bowhead whales
A unique collection of prehistoric bowhead whale bones, dating back 11,000 years, reveals a previously untold story of the relative impacts of humans on nature. The time series of ancient fossils show that commercial hunting ...
Medical Xpress / Brain tumors hijack sugar metabolism to evade immune attack, study shows
Northwestern Medicine scientists have discovered that specialized immune cells within the glioblastoma tumor metabolize fructose to suppress immune responses and promote tumor growth, reports a study published in the Proceedings ...
Phys.org / From dust to planets: Parabolic flight reveal a turbulent path
How does fine dust aggregate into building blocks that ultimately form entire planets like our Earth? A research team led by the University of Bern, with the participation of ETH Zurich, the University of Zurich and the National ...
Phys.org / Nano 3D metallic parts turn out to be surprisingly strong despite defects
Scientists at Caltech have figured out how to precisely engineer tiny three-dimensional (3D) metallic pieces with nanoscale dimensions. The process can work with any metal or metal alloy and yields components of surprising ...
Phys.org / 'Rock clock' refines time measurement of Earth's early complex animal life
How can we measure time more than 500 million years into the past? A study recently published in Nature Communications by researchers at the University of Lausanne presents a new geological "rock clock" that allows major ...
Phys.org / Genetic analyses show that many sponge species in the Indo-Pacific are regionally unique
The Indo-Pacific is the largest marine biogeographical region on Earth and a global center of marine biodiversity. Nevertheless, there are gaps remaining in our understanding of the diversity, distribution, and endemism of ...
