Despite the astonishing successes of quantum mechanics, due to some fundamental problems such as the measurement problem and quantum arrival time problem, the predictions of the theory are in some cases not quite clear and unique.

The measurement and quantum arrival time problems have originated various predictions for the join spatiotemporal distribution of particle detection events, derived from different formulations and interpretations of the quantum theory. By reworking the famous double-slit experiment, the authors propose a realizable setup to probe such predictions.

Your knees have lots of parts, and you use them a lot, so there’s plenty that could go wrong. WebMD explains common things that can cause knee pain.

The UN General Assembly on Thursday adopted a landmark resolution on the promotion of “safe, secure and trustworthy” artificial intelligence (AI) systems that will also benefit sustainable development for all.

Leading computer scientists from around the world have shared their vision for the future of artificial intelligence—and it resembles the capabilities of Star Trek character “The Borg.”

Weak fluctuations in superconductivity, a precursor phenomenon to superconductivity, have been successfully detected by a research group at the Tokyo Institute of Technology (Tokyo Tech). This breakthrough was achieved by measuring the thermoelectric effect in superconductors over a wide range of magnetic fields and over a wide range of temperatures, from much higher than the superconducting transition temperature to very low temperatures near absolute zero. The results of this study were published online in Nature Communications on March 16, 2024.

This revealed the full picture of fluctuations in superconductivity with respect to temperature and magnetic field, and demonstrated that the origin of the anomalous metallic state in magnetic fields—which has been an unsolved problem in the field of two-dimensional superconductivity for 30 years—is the existence of a quantum critical point, where quantum fluctuations are at their strongest.

“Cannabis vapes are newly regulated products in Canada, so we don’t yet have much scientific data about them,” said Dr. Andrew Waye. “This is an opportunity for us to look at some of the questions concerning the risks and unknowns of cannabis vapes.”

Do vapes pose health risks on par with the very tobacco and cannabis products it’s using to safeguard against? This is what a recent study presented at the ACS (American Chemical Society) Spring 2024 meeting hopes to address as a team of researchers investigated the potential health risks that vaping devices could pose, specifically pertaining to the vaping liquids that possess toxic metal nanoparticles, with both regulated and unregulated vaping devices. This study holds the potential to help researchers, medical professionals, and the public better understand the long-term health risks by vaping, which until now have been deemed a “safer” alternative to smoking cigarettes or cannabis.
