Tech Xplore / Metal alloys defy the deep freeze, staying tough at -253°C
Scientists have discovered a class of metal that can unexpectedly resist extreme cold using an unusual mechanism. Normally such temperatures would make similar materials brittle and vulnerable to breaking. The findings, published ...
Phys.org / Optical skyrmions can control the motion of magnetic skyrmions
Magnetic skyrmions (MSks) are swirling patterns of magnetization that form inside certain magnetic materials. They can behave like actual particles in many ways, exhibiting a stable internal structure and distinct boundaries. ...
Phys.org / Planetary systems reveal two distinct families tied to their host stars
Analyzing a sample of 300 of the best-characterized planetary systems among the more than 1,000 known in the Milky Way, an international research team led by the Italian National Institute for Astrophysics (INAF) has discovered ...
Medical Xpress / Same duty cycle, very different outcomes: What tough materials taught us about histotripsy
One of the questions that stayed with me throughout my Ph.D. was surprisingly simple: Why are some tissues so much harder to break down with histotripsy than others? Histotripsy is a focused ultrasound technique that uses ...
Phys.org / From nonmagnetic to magnetic: A 2D semiconductor with electrically tunable magnetism
Researchers from the National University of Singapore (NUS), in collaboration with scientists from institutions in Switzerland, the Czech Republic and Germany, have demonstrated a way to introduce magnetism into an otherwise ...
Tech Xplore / Vapor-clearing channels could keep powerful chips cool with less risk of short circuits
Integrated circuits are electronic chips containing the interconnected components that process information or control electrical signals inside many electronic devices. These chips are known to generate heat as they operate, ...
Phys.org / One step closer to quantum computers that can correct their own mistakes
Researchers from Rutgers, IBM and collaborating institutions have shown that a quantum computer can check what is happening inside it and respond while it is running, repeatedly resetting parts of the system to bring chaotic ...
Phys.org / New sensor uses slowed light to detect gravitational pull of tiny objects
Gravity, the attraction between objects with mass, is the weakest of the four fundamental forces governing physical processes. Detecting the tiny gravitational pull of objects that are just a few millimeters in size and have ...
Phys.org / Ultrafast core-level spectroscopy reveals elusive precursors of exciton condensation in quantum materials
Many fascinating phases in quantum materials emerge when electrons, atoms and other microscopic components begin to act collectively. But these phases do not necessarily appear out of nowhere when a material crosses a transition ...
Phys.org / New 'computational microscope' simulates DNA packaging at more than ten times previous scale
The DNA in our cells wraps around proteins called histones to form nucleosomes, which organize into chromatin. This organization helps pack genetic material into the nucleus and influences how easily genes can be read and ...
Phys.org / Pottery styles reveal contrasting paths to social complexity in Neolithic Europe
Societal changes do not follow a linear path—this also holds true for Neolithic Europe, approximately 8,000 to 4,000 years ago. Two researchers from the National Academy of Sciences of Ukraine (NASU) and the Leibniz-Zentrum ...
Phys.org / Acoustic experiments confirm topology can persist at gapless critical points
Two studies on critical topology have recently been published in the journal Nature. These studies were led by the teams of Prof. Baile Zhang at Nanyang Technological University, Singapore, and Prof. Jianhua Jiang at the ...
