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…”
Nano Racetracks…
In this image, optical pulses (solitons) can be seen circling through conjoined optical tracks. (Image: Yuan, Bowers, Vahala, et al.) An animated gif is at the original link below. Topics: Applied Physics, Astronomy, Electrical Engineering, Materials Science, Nanoengineering, Optics (Nanowerk News) When we last checked in with Caltech’s Kerry Vahala three years ago, his labContinue reading “Nano Racetracks…”
All-Solid-State Batteries
Comparison of cathode volume changes in all-solid-state cells under low-pressure operation. 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…”

Power and Resources…
French economist Thomas Piketty compares the US economy to Europe in the Gilded Age. Oregon Live, 2014 Topics: Civics, Civil Rights, Civilization, Climate Change, Democracy, Existentialism, Fascism Thomas Piketty wrote “Capital in the 21st Century” in 2013 centered on the wealth inequality we can see all around us. I can see more house-less citizens onContinue reading “Power and Resources…”

Quantum Switch…
Credit: CC0 Public Domain Topics: Condensed Matter Physics, Materials Science, Quantum Computer, Quantum Mechanics Quantum scientists have discovered a rare phenomenon that could hold the key to creating a ‘perfect switch’ in quantum devices, which flips between being an insulator and a superconductor. The research, led by the University of Bristol and published in Science, found theseContinue reading “Quantum Switch…”
Dark Matter, Ordinary Matter…
Topics: Astronomy, Astrophysics, Dark Matter, Research, Theoretical Physics Dark matter, composed of particles that do not reflect, emit, or absorb light, is predicted to make up most of the matter in the universe. However, its lack of interactions with light prevents its direct detection using conventional experimental methods. Physicists have been trying to devise alternativeContinue reading “Dark Matter, Ordinary Matter…”
