Cooling Circuitry…
Illustration of a UCLA-developed solid-state thermal transistor using an electric field to control heat movement. Credit: H-Lab/UCLA Topics: Applied Physics, Battery, Chemistry, Electrical Engineering, Energy, Thermodynamics A new thermal transistor can control heat as precisely as an electrical transistor can control electricity. From smartphones to supercomputers, electronics have a heat problem. Modern computer chips suffer from microscopicContinue reading “Cooling Circuitry…”
Fusion’s Holy Grail…
A view of the assembled experimental JT-60SA Tokamak nuclear fusion facility outside Tokyo, Japan. JT-60SA.ORG Topics: Applied Physics, Economics, Energy, Heliophysics, Nuclear Fusion, Quantum Mechanics Japan and the European Union have officially inaugurated testing at the world’s largest experimental nuclear fusion plant. Located roughly 85 miles north of Tokyo, the six-story JT-60SA “tokamak” facility heats plasmaContinue reading “Fusion’s Holy Grail…”
‘Teleporting’ Images…
High-dimensional quantum transport enabled by nonlinear detection. In our concept, information is encoded on a coherent source and overlapped with a single photon from an entangled pair in a nonlinear crystal for up-conversion by sum frequency generation, the latter acting as a nonlinear spatial mode detector. The bright source is necessary to achieve the efficiencyContinue reading “‘Teleporting’ Images…”

Cate Cox is a married suburban mother with two children. She previously lived in a suburb of Dallas, Texas, but due to her condition,Continue reading “Births, Stats, Mathematics…”
The “Tiny Ten”…
Researchers are working to overcome challenges related to nanoscale optoelectronic interconnects, which use light to transmit signals around an integrated circuit. IMAGE: PROVIDED BY NCNST Topics: Biology, Materials Science, Nanoengineering, Nanomaterials, Nanotechnology, Quantum Mechanics The promise of nanotechnology, the engineering of machines and systems at the nanoscale, is anything but tiny. Over the past decade alone,Continue reading “The “Tiny Ten”…”
Funny How It’s Not Aliens…
The 3D model of Menga was drawn with AutoCAD, showing the biofacies (microfacies) present in the stones. The fourth pillar, currently missing, has been added, while capstones C-2, C-3, C-4, and C-5 have been removed in order to show the interior of the monument (Lozano Rodríguez et al.25). (a) Pillar P-3 with examples of biofaciesContinue reading “Funny How It’s Not Aliens…”

Credit: Korea Institute of Science and Technology Topics: Batteries, Chemistry, Climate Change, Lithium, Materials Science, Nanomaterials Often referred to as the “dream batteries,” all-solid-state batteries are the next generation of batteries that many battery manufacturers are competing to bring to market. Unlike lithium-ion batteries,Continue reading “All-Solid-State Batteries”
The Red Road…
Topics: Civics, Civil Rights, Civilization, Democracy, Existentialism, Fascism I can hear an irritated counterthrust already. The president has not driven the United States into a recession during his almost seven years in office. Unemployment stands at a respectable 4.6 percent. Well, fine. But the other side of the ledger groans with distress: a tax codeContinue reading “The Red Road…”
