Phys.org / Ultra-thin metasurface chip turns invisible infrared light into steerable visible beams
The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science Research Center at the CUNY ...
Phys.org / Two huge hot blobs of rock influence Earth's magnetic field, study reveals
Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 km. Consequently, little ...
Phys.org / Are cats 'vegan' meat eaters? Why isotopic signatures of feline fur could trick us into thinking that way
Cats—unlike humans—are true carnivores: they must eat meat to survive because their bodies can't draw some essential nutrients from plants. By looking at tissues, researchers can get a good understanding of what foods ...
Phys.org / Ancient Alaskan site may help explain how the first people arrived in North America
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Phys.org / 91-qubit processor accurately simulates many-body quantum chaos
Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a way by leveraging error ...
Phys.org / A student made cosmic dust in her lab—what she found could help us understand how life started on Earth
A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed ...
Phys.org / Long-period Jupiter-like exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size ...
Phys.org / Experiments clear up confusion over the form of solid methane
Through a combination of high-pressure experiments and optical spectroscopy, physicists have revealed new insights into the structural forms of solid methane. Led by Mengnan Wang at the University of Edinburgh in the UK, ...
Phys.org / Tibet's tectonic clash: New satellite view suggests weaker fault lines
A study on tectonic plates that converge on the Tibetan Plateau has shown that Earth's fault lines are far weaker and the continents are less rigid than scientists previously thought. This finding is based on ground-monitoring ...
Phys.org / Bubble bots: Simple biocompatible microrobots autonomously target tumors
The potential of microrobots is enormous. These miniature objects can be designed to carry out actions within the body, such as sensing biomarkers, manipulating objects like blood clots, or delivering drug therapies to tumor ...
Phys.org / Earth's largest volcanic event reshaped an oceanic plate, seismic wave analysis reveals
A research group has revealed through seismic wave analysis that the oceanic plate beneath the Ontong Java Plateau—the world's largest oceanic plateau—was extensively altered by massive volcanic activity during its formation. ...
Phys.org / Unraveling the physics behind Kamchatka's 73-year earthquake cycle
A research team from University of Tsukuba and collaborating institutions has clarified why M9-class megathrust earthquakes recur off the Kamchatka Peninsula with an unusually short cycle of 73 years. By analyzing the rupture ...
