Artificial neurons emulate biological counterparts to enable synergetic operation
Posted by Dan Breeden in category: biological
An organic artificial spiking neuron based on nonlinear ionoelectronic phenomena is reported that is sensitive to ionic and biomolecular species common in neuronal signalling. The neuron realistically emulates the function and firing properties of biological neurons and enables biohybrid interfaces made of artificial and biological components that function in real time.

Study unveils an antiferromagnetic metal phase in an electron-doped rare-earth nickelate
Posted by Jose Ruben Rodriguez Fuentes in categories: materials, particle physics
Researchers at Harvard University, the Lawrence Berkeley National Laboratory, Arizona State University, and other institutes in the United States have recently observed an antiferromagnetic metal phase in electron-doped NdNiO3 a material known to be a non-collinear antiferromagnet (i.e., exhibiting an onset of antiferromagnetic ordering that is concomitant with a transition into an insulating state).
“Previous works on the rare-earth nickelates (RNiO3) have found them to host a rather exotic phase of magnetism known as a ‘noncollinear antiferromagnet,’” Qi Song, Spencer Doyle, Luca Moreschini and Julia A. Mundy, Four of the researchers who carried out the study, told Phys.org.
“This type of magnet has unique potential applications in the field of spintronics, yet rare-earth nickelates famously change spontaneously from being metallic to insulating at the exact same temperature that this noncollinear antiferromagnet phase turns on. We wanted to see if we could somehow modify one of these materials in a way so that it remained metallic, but still had this interesting magnetic phase.”

Scientists make a rare find: A Solar system with three Super-Earths
Posted by Dan Breeden in categories: physics, space
Three Super-Earths and two Super-Mercuries, a type of planet that is extraordinarily rare and distinct, haʋe Ƅeen found in a star systeм Ƅy astronoмers. Super-Mercuries are so uncoммon—only eight haʋe Ƅeen found so far—that they are extreмely rare.
ESPRESSO’s spectrograph detected two ‘super-Mercury’ worlds in the star systeм HD 23472. Astronoмers haʋe discoʋered that these planets are extreмely rare. This study, puƄlished in Astronoмy &aмp; Astrophysics, looked at how the coмposition of tiny planets ʋaries with planet position, teмperature, and star attriƄutes.
The reason for oƄserʋing this planetary systeм, according to Susana Barros, a researcher at the Institute of Astrophysics e Ciências do Espaço (IA) who led the project, is to characterise the coмposition of sмall planets and to study the transition Ƅetween haʋing an atмosphere and not haʋing an atмosphere.

The Evolution of Warfare in the 21st Century — Part One: Here Come the Drones
Posted by 21st Century Tech Blog in categories: drones, military, robotics/AI
Russia and Ukraine have deployed an army of drones in their conflict. Mechanized warfare is about to dramatically change in the 21st century.
The Russia-Ukraine war is using military drones not just to gather intelligence, but also to kill. Are autonomous robot armies to follow?
