6+ hour, 20+ min ago   (417+ words) Physicists have uncovered an in-plane Hall response that overturns a century-old assumption about how this famous electrical effect works. The discovery could eventually make multidirectional magnetic sensing possible with one tiny device....

2+ day, 23+ hour ago   (702+ words) The Pentagon has moved directed-energy counter-drone systems into yearlong operational trials at U.S. military bases to assess their readiness for routine installation defense. The effort will... U.S. Begins Yearlong Directed Energy Counter-Drone Trials Across Five Military Bases. The Pentagon has moved directed-energy…...

6+ hour, 50+ min ago   (658+ words) For decades, one of the most stubborn bottlenecks in building faster, greener computer memory has been a simple question of timing: how do you deliver an electrical pulse short enough and powerful enough to flip a magnetic bit in a…...

7+ hour, 50+ min ago   (637+ words) Titanium is one of the most demanding materials in modern manufacturing. It is strong, lightweight, corrosion-resistant, and biocompatible, which makes it indispensable for aerospace components, medical implants, and precision microdevices. Yet those same qualities make titanium notoriously difficult to machine…...

8+ hour, 12+ min ago   (86+ words) A pinch of graphene may be all it takes to make liquid crystals dramatically more useful in the infrared. Researchers in Japan have shown that dispersing tiny flakes of the one-atom-thick carbon material into a common nematic liquid crystal boosts…...

22+ hour, 15+ min ago   (682+ words) Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall off....

19+ hour, 33+ min ago   (761+ words) {“title”:”Chip-Scale Optical Circulator Promises Bidirectional 800G Fibre Transmission”,”html”:”Optical networks are built on a deceptively simple problem: light travelling in a fibre almost always wants to go both ways at once, and keeping those two directions from interfering with…...

20+ hour, 8+ min ago   (534+ words) Researchers at the University of Toronto and the University of Saskatchewan have engineered a compact, far-red light-responsive protein pair that could redefine how scientists switch molecules on and off inside living cells. The new system, described in Nature Methods, pairs…...

1+ day, 1+ hour ago   (73+ words) Light passing through a carefully engineered nanostructure can behave in ways that ordinary optics never allows. It can cancel itself out at certain frequencies, reinforce itself at others, and produce sharply asymmetric spectral lines that seem to defy the smooth,…...

1+ day, 7+ hour ago   (547+ words) Why organizations are moving past full digital sovereignty Canada eyes researchers looking to leave ‘hostile’ US AI-powered fraud is becoming personal: How cybercriminals are exploiting trust at unprecedented scale Robotics meets ultrafast lasers: Could a new generation of tools transform…...
