A research team in Germany has achieved a stunning theoretical breakthrough that could reshape one of physics’ oldest foundations after demonstrating that the no longer holds true for objects on the atomic scale. Their findings, made by Eric Lutz, PhD, a physics professor and Milton Aguilar, PhD, a postdoctoral researcher at the University of Stuttgart, show that quantum systems can …

Chemicals All chemicals were used without further purification after purchase: gold(III) chloride trihydrate (≥99.9% trace metals basis, HAuCl4·3H2O, Sigma-Aldrich), sodium borohydride (99%, NaBH4, Sigma-Aldrich), sodium iodide (99.999%, NaI, Sigma-Aldrich), sodium bromide (≥99.99%, NaBr, Sigma-Aldrich), sodium chloride (99.3%, NaCl, Fisher Scientific), potassium iodide (≥99.5%, KI, Sigma-Aldrich), silver nitrate (≥99.0%, AgNO3, Sigma-Aldrich), sodium tetrachloropalladate(II) (approximately 36%, Na2PdCl4, Acros Organics), l-ascorbic acid (BioXtra, …

Researchers in China have opened a new window into the deep past by blasting dinosaur eggs with a laser, dating them directly for the first time. A micro-laser was used to vaporize small portions of an eggshell, which released a cloud of radioactive uranium atoms. Since uranium decays into lead at a known, steady rate, researchers could ascertain the eggs’ …

Optical tweezer arrays 1,2 have transformed atomic and molecular physics, now forming the backbone for a range of leading experiments in quantum computing 3–8, simulation 1,9–12, and metrology 13–15. Typical experiments trap tens to hundreds of atomic qubits, and recently systems with around one thousand atoms were realized without defining qubits or demonstrating coherent control 16–18. However, scaling to thousands …

CHINA — A clutch of 28 dinosaur eggs found in the Qinglongshan fossil reserve in central China is about 86 million years old, according to scientists who used an “atomic clock” method to date the samples. Researchers said they now hope the eggs, and the technique employed to evaluate their age, might help to reveal how dinosaurs living in China’s …

A cryogenic microscope that fits on a laboratory bench has now let scientists watch electrons shake graphene’s atoms in real time, revealing something called “phasons.” The work ties those shivers to the zero-resistance current and odd “strange metal” signals that appear when two graphene sheets are rotated by about 1.1° or what’s referred to as the “magic angle.” …
