Phys.org / Tectonic influence on Cenozoic mammal richness
Speciation and sedimentation are driven by tectonic activity, which causes fossil and rock records to share common patterns through time. During the Miocene, the Basin and Range (BR) of western North America arose through ...
Phys.org / Discovery of segmented Fermi surface induced by Cooper pair momentum on a hybrid material platform
In a new report now published in Science, primary authors Zhen Zhu, Michal Papaj, and an international research team in physics, materials science, and condensed matter at the Jiao Tong University, China, Massachusetts Institute ...
Phys.org / Demonstration of diamond nuclear spin gyroscope
In a new report now published in Science Advances, Andrey Jarmola and an international research team in physics and materials in the U.S. and Germany demonstrated the function of a rotation sensor based on the Nitrogen-14 ...
Medical Xpress / Monitoring blood flow velocity with a flexible Doppler ultrasound device
Researchers aim to implement a clinical strategy to monitor vascular conditions such as restenosis and thrombosis after vascular reconstruction procedures. Conventional ultrasound probes are rigid devices for patients with ...
Tech Xplore / Developing 3-D electronics with pre-distorted pattern generation and thermoforming
Three-dimensional electronics (3-DE) is attracting much interest due to the increasing demands for seamless integration on curved surfaces. Nevertheless, it is challenging to develop 3-DE with high customizable conformity ...
Medical Xpress / MagneTEskin – Reconstructing the skin with magnetically induced assembly of microtissue cores
Autologous skin grafting is still the gold standard of wound repair. In a new report now published on Science Advances, Christiane Fuchs, and a research team in photomedicine and dermatology at the Massachusetts General Hospital ...
Phys.org / Efficient light-emitting diodes based on oriented perovskite nanoparticles
Planar perovskite light-emitting diodes (LEDs) are high-performance and cost-effective electroluminescence devices that are ideal for large-area display and lighting applications. By exploring the emission layers with high ...
Phys.org / Inter-atomic photon emission during contact-electrification
Contact electrification can arise when physical contact occurs between two materials. In a new report now published on Science Advances, Ding Li, and a team of scientists in nanoscience, nanoenergy and materials science in ...
Phys.org / Bioinspired electromechanical nanogenerators to regulate cell activity
The extracellular matrix (ECM) including three-dimensional (3D) network and bioelectricity can profoundly influence cell development, migration, and functional expression. In a new report now published on Science Advances, ...
Medical Xpress / Simultaneous acoustic energy transfer and communication in neuroscience and cardiovascular medicine
Implantable medical devices including cardiac pacemakers and brain pacemakers are increasingly prevalent, although replacing their batteries surgically is a drawback for long-term functionality and patient health. Current ...
Phys.org / Implementing a 46-node quantum metropolitan area network
Quantum key distribution (QKD) is a method used for secure or secret key exchanges between two remote users. Using secure communication, cyberscientists ultimately aim to establish a global quantum network. Existing field ...
Phys.org / Load-bearing entanglements in polymer glasses
The role of entanglements can determine the mechanical properties of glass polymer blends. In a new report now published on Science Advances, Cynthia Bukowski and a research team in polymer science and biomolecular engineering ...
Phys.org / Millimeter-scale chip-based supercontinuum generation
In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...
Medical Xpress / Personalized 3-D magnetic micromachines from patient blood-derived biomaterials
Wireless micromachines have increased the scope for applications in biomedicine, although their risks relative to minimal biocompatibility need be lessened. Most materials are not intrinsically biocompatible in physiological ...
Phys.org / Cristae-dependent quality control of the mitochondrial genome
Mitochondrial genomes (MtDNA) comprise essential subunits of the mitochondrial respiratory chain; therefore, mutations in mtDNA can reduce cellular energy support and cause mitochondrial diseases. Researchers seek to understand ...
