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 ...
Phys.org / Physicists trace the sun's magnetic engine, 200,000 kilometers below its surface
Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and migrate toward the ...
Phys.org / Quantum-inspired laser system delivers distance measurements with sub-millimeter accuracy
A new laser range-finding technique, inspired by quantum physics, that can measure distances under strong solar background has been demonstrated by researchers at the University of Bristol. The team has proved their hypothesis ...
Phys.org / Carbon nanotube 'black paint' absorbs terahertz radiation to cut 6G interference
Skoltech researchers and their colleagues from KTH Royal Institute of Technology, Sweden, have created an important building block for future 6G communication technology, which will make wireless data transfer at superior ...
Phys.org / What's in your lipstick and water? New test flags hidden mutagens
Substances capable of mutating human genetic material—altering and permanently damaging it—are present in many everyday products. Researchers at Justus Liebig University Giessen (JLU) have, for the first time, detected ...
Phys.org / Graphene sensors stay stable in liquids, boosting sensitivity up to 20 times
Accurately measuring small shifts in biological markers, like proteins and neurotransmitters, or harmful chemicals in the water supply, can identify critical problems before they have a chance to impact patients or the environment. ...
Phys.org / Asteroid Bennu's rugged surface baffled NASA—now, we finally know why
In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier observations from Earth-based ...
Phys.org / 'Conflict entrepreneurs': Examining divisive political rhetoric and the pursuit of celebrity by politicians
American politics is increasingly characterized by high levels of polarization and divisive rhetoric, despite stated preferences among voters for civility and substantive debate. Sean J. Westwood and colleagues sought to ...
Phys.org / When it comes to networks, nature has an edge
Networks exist in both nature—such as biological systems like food webs and gene regulatory networks—and in engineered systems as seen in power grids. Though natural and engineered systems share an overarching goal—providing ...
Phys.org / Perovskite crystals can host qubits, challenging long-held assumptions
For the first time, researchers have demonstrated that the properties of the perovskite family of materials can be used to create so-called quantum bits. The findings, published in the journal Nature Communications, pave ...
