Conservation laws serve as a cornerstone in modelling the evolution of physical quantities such as mass, momentum and energy. Recent advances have placed a particular emphasis on systems where the ...

Canada's biodiversity is in decline. Globally, climate change, urbanization, overexploitation of resources and habitat loss are combining to drive biodiversity loss across all ecosystems. The recent ...

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when a single photon is converted into a ...

Figure 1. Correlated spectrum of angular momentum and energy (SAME) at the tunnel exit for photoelectrons originating from ionization of the helium atom exposed to (1) circularly or (2) elliptically ...

Indonesia’s recently revised conservation law retains a heavy focus on terrestrial protection and largely ignores marine and fisheries issues, experts say. Despite improvements such as clearer ...
