In His Image: Cloning of a Man
"In 1978, J.B. Lippincott Company published as fact a story previously told only as science fiction: the tale of an eccentric, wealthy businessman longing for a son -- but not exactly a son. Instead, the California millionaire in his twilight years is looking for more than an heir: he is looking for a clone of himself."

Cosmology in ghost-free bigravity theory with twin matter fluids: The origin of "dark matter" [CL] | arXiver
"We study dynamics of Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime based on the ghost-free bigravity theory. Assuming the coupling parameters guaranteeing the existence of de Sitter space as well as Minkowski spacetime, we find two stable attractors for spacetime with “twin” dust matter fields: One is de Sitter accelerating universe and the other is matter dominated universe. Although a considerable number of initial data leads to de Sitter universe, we also find matter dominated universe or spacetime with a future singularity for some initial data. The cosmic no-hair conjecture does not exactly hold..." Science writing as demented poetry. My favourite.

LHC team observes first instance of D-mesons oscillating between matter and antimatter
"Put simply, antimatter is identical to matter except that it exists with an opposite electrical charge. In this new research, the team was studying mesons—a group that along with other particles are made up of quarks. Mesons are made up of just two quarks, one matter, the other antimatter. Research over the years has led to theories that the quarks that exist as part of mesons, can oscillate between matter and antimatter."
