Switching nanomagnets using infrared lasers

Posted by in categories: nanotechnology, physics

When molecules are irradiated with infrared light, they begin to vibrate due to the energy supply. For Andreas Hauser from the Institute of Experimental Physics at Graz University of Technology (TU Graz), this well-known phenomenon was the starting point for considering whether these oscillations could also be used to generate magnetic fields.

Wanted: advanced atomic vapor sensors for quantum information, imaging, communications, and RF electrometry

Posted by in categories: military, particle physics, quantum physics

ARLINGTON, Va. – U.S. military researchers are approaching industry to enhance atomic vapor sensors for electric field sensing, imaging, communications, and quantum information science (QIS).

Officials of the U.S. Defense Advanced research Projects Agency (DARPA) in Arlington, Va., have issued a broad agency announcement (HR001124S0031) for the Enhancing Quantum Sensor Technologies with Rydberg Atoms (EQSTRA) program.

EQSTRA seeks to enhance the performance, capabilities, and maturity of atomic vapor sensors for future compact, calibration-free, small, and lightweight devices with low drift, and quantum-limited accuracy and sensitivity.

A 25-year quest for the Holy Grail of evolutionary biology

Posted by in category: biological

When I started my postdoc in 1998, I think it is safe to say that the Holy Grail (or maybe Rosetta Stone) for many evolutionary biologists was a concept called the Adaptive Landscape. The reason for such exalted status is that the adaptive landscape was then – and remains – the only formal quantitative way to predict and interpret an adaptive radiation of few organisms into many. I was heavily indoctrinated into this framework — as my postdoc was at UBC during precisely the time when Dolph Schluter was writing his now-classic book The Ecology of Adaptive Radiation.

US Wants To Create ‘Hellscape’ Of Drones If China Attacks Taiwan

Posted by in categories: drones, robotics/AI

Drone wars, what haven’t we seen. If we look at active wars and mark those drones gen1, do we have in army hangars strategic gen 3 or 4 drones? what do they look like, how does that c&c works?


Top Admiral: “I want to turn the Taiwan Strait into an unmanned hellscape using a number of classified capabilities.”

Molecules in Motion: Advanced Spectroscopy Captures Molecular Dynamics in Real-Time

Posted by in categories: biological, chemistry, evolution, particle physics

Researchers have developed a new method that uses attosecond core-level spectroscopy to capture molecular dynamics in real time.

The mechanisms behind chemical reactions are complex, involving many dynamic processes that affect both the electrons and the nuclei of the involved atoms. Frequently, the strongly coupled electron and nuclear dynamics trigger radiation-less relaxation processes known as conical intersections. These dynamics underpin many significant biological and chemical functions but are notoriously difficult to detect experimentally.

The challenge in studying these dynamics stems from the difficulty of tracing the nuclear and electronic motion simultaneously. Their dynamics are intertwined and occur on ultrafast timescales, which has made capturing the molecular dynamical evolution in real time a major challenge for both physicists and chemists in recent years.
