Two Chinese teams claim to have reached primacy with quantum computers

https://phys.org/news/2021-10-chinese-teams-primacy-quantum.html "quantum primacy is the performance of calculations that are not feasible on conventional computers... thus far have been met with skepticism... In this new effort, both teams are claiming... no room for doubt... In the first effort...

Bioplastics can be chemically recycled into nitrogen-rich fertilizers in a facile and environmentally friendly way

https://www.titech.ac.jp/english/news/2021/062171 "The team focused on poly (isosorbide carbonate), or "PIC," a type of bio-based polycarbonate that has garnered much attention as an alternative to petroleum-based polycarbonates. PIC is produced using a non-toxic material derived from glucose called isosorbide (ISB) as a monomer. The interesting part is that the carbonate links that join the ISB units can be severed using ammonia (NH3) in a process known as ‘ammonolysis’. The process produces urea, a nitrogen-rich molecule that is widely used as a fertilizer" Related:   Hard-To-Recycle Plastics Are Now Being Made Into Zero Waste “Concrete” Blocks https://www.apartmenttherapy.com/recycled-plastic-concrete-37041922 Researchers building green fertilizer system to reuse wastes, cut greenhouse gas emissions https://www.eurekalert.org/news-releases/998970 Chemical fertilizer is a climate disaster.

IU physicists lead world's most precise measurement of neutron lifetime

https://news.iu.edu/stories/2021/10/iub/13-physics-neutron-lifetime-measurement-study.html The process by which a neutron ‘decays’ into a proton — with an emission of a light electron and an almost massless neutrino — is of great interest to physicists.  “...understanding the precise lifetime of the neutron can shed light on how the universe developed ... and show flaws in our model of the subatomic universe that we know exist but nobody has yet been able to find.”  The neutron source was the Ultracold Neutron source at Los Alamos.  The experiment captures these neutrons, whose temperatures are lowered to nearly absolute zero, inside a “bathtub” lined with about 4,000 magnets.  After waiting 30 to 90 minutes, researchers count the surviving neutrons in the tub as they’re levitated against gravity by the force of the magnets.  The trap allows neutrons to remain stored for more than 11 days.  This is significantly longer than earlier designs, minimizing the need for systematic correction
