Finding hidden regularities in nature: Researchers apply deep learning to X-ray diffraction
X-ray diffraction (XRD) is an experimental technique to discern the atomic structure of a material by irradiating it with X-rays at different angles. Essentially, the intensity of the reflected X-rays becomes high at specific irradiation angles, producing a pattern of diffraction peaks. An XRD serves as a fingerprint for a material since each substance produces a unique pattern.

Could more acidic air keep viruses from spreading?
Aerosols in indoor air can vary in acidity, and the acidity determines how long viruses remain infectious in the air, research finds. Viruses such as SARS-CoV-2, influenza, and others travel from person to person by "hitchhiking" on aerosols. An infected person expels the finely dispersed particles when they cough, sneeze, or just exhale. Someone else can then inhale them. It's not clear how long

Nvidia RTX Ada Titan Leaks Show Quad-Slot Monstrosity, Dual 16-pin Connectors
(Credit: Moores Law is Dead) When Nvidia launched its 40-series Ada Lovelace GPUs, it conspicuously revealed the 4090 does not use the full-fat AD102 silicon. Instead, it's a cut-down version, meaning Nvidia left some horsepower waiting in the wings just in case it needed it. We always figured that would be a 4090 Ti, launched when necessary to blunt an attack from AMD. Now it seems like the comp

Mid life career change – what to avoid with a view to AI/automation
I want this to be a more general discussion but i'll give some details. I'm 40. So, my window is 25 years. My main idea right now is social work. It would be cool if people could give a window for how long it would take for any listed career to reduce in number of jobs, or to become obsolete. Maybe that way it would be useful for people of varying ages. submitted by /u/throw1274637374 [link] [com
