Phys.org / The hypothalamus predates the origin of vertebrates
The hypothalamus is involved during the coordination of neuroendocrine functions in vertebrates and their evolutionary origin can be described using integrated transcriptome or connectome brain maps of swimming tadpoles of ...
Phys.org / A universal method to easily design tough and stretchable hydrogels
In a new report in NPG Asia materials, Chisa Norioka and a team of scientists in Chemistry and Materials Engineering in Japan, detailed a universal method to easily prepare tough and stretchable hydrogels without special ...
Phys.org / Structure motif-centric learning framework for inorganic crystalline systems
Physical principles can be incorporated in a machine learning architecture as a fundamental setup to develop artificial intelligence for inorganic materials. In a new report now on Science Advances, Huta R. Banjade, and a ...
Phys.org / Using flexible microparticles as drug carriers to shuttle nanoparticles to the vascular wall
Drug carriers that target the vascular endothelium must adhere to the endothelial vessel wall to achieve clinical stability. The particle size is a critical physical property to prescribe particle margination within biological ...
Phys.org / Self-organization of nanoparticles and molecules in periodic Liesegang-type structures
Chemical organization in reaction-diffusion systems offer a strategy to generate materials with ordered morphologies and architecture. Periodic structures can be formed using molecules or nanoparticles. An emerging frontier ...
Phys.org / Boron insertion into alkyl ether bonds via zinc/nickel tandem catalysis
The carbon-oxygen (C-O) bond in alkyl ethers can be cleaved using mild methods to simplify chemical syntheses by elaborating robust, readily available precursors. In a new report now on Science, Hairong Lyu and a research ...
Phys.org / Understanding the charge pumping and relaxation of the chiral anomaly in a Dirac semimetal
The 3D Dirac and Weyl semimetals can be characterized by a charge chirality with the parallel or antiparallel locking of electron spin in its momentum. Such materials can exhibit a chiral magnetic effect associated with the ...
Phys.org / Breakthrough purification of fossil pollen using a new large-particle on-chip sorter
Particle sorting is fundamental to biological and medical research, although existing methods are unable to sort large-sized particles via high-throughput sorting. In a new report, Y. Kasai and a research team in Japan, Germany ...
Medical Xpress / Value and neural representations during goal-directed behavior
In its hedonistic aspects, value is often associated with reward. However, when circumstances change, value must also change. In this work, G. Castegnetti and a research team at the Institute of cognitive neuroscience and ...
Phys.org / Holographic metasurface gas sensors for instantaneous visual alarms
Biological and chemical substances can be rapidly detected in real-time for public health and environmental monitoring purposes. In a new report now on Science Advances, Inki Kim and a research team in mechanical engineering, ...
Phys.org / Designed proteins assemble antibodies into modular nanocages
In a new report now published on Science, Robby Divine and an interdisciplinary research team at the department of biochemistry, regenerative medicine, and vaccines and infectious disease at the University of Washington U.S. ...
Phys.org / Experimental observation of the elastic range scaling in turbulent flow with polymer additives
When long-chain flexible polymers are dissolved in a turbulent flow, the flow properties can be changed drastically by reducing the drag and enhancing the mixing. A fundamental riddle in materials science is to understand ...
Phys.org / Topological insulator metamaterial with giant circular photogalvanic effect
Topological insulators have notable manifestations of electronic properties. The helicity-dependent photocurrents in such devices are underpinned by spin momentum-locking of surface Dirac electrons that are weak and easily ...
Phys.org / Gate-controlled ground state crossover in a two-dimensional superconductor
In the paired fermion systems, the Bardeen-Cooper-Schrieffer (BCS) superfluidity and Bose-Einstein condensation (BEC) are two extreme limits of the ground state. In a new report in Science, Yuji Nakagawa and a team of scientists ...
Phys.org / High-order superlattices by rolling up van der Waals heterostructures
Two-dimensional (2D) materials and van der Waals (vdW) heterostructures are flexible materials with distinct atomic layers beyond traditional units of lattice-matching requirements. Nevertheless, the 2D van der Waals structures ...
