Ancestors of Primates and Marsupials May Have Left Trees to Survive End-Cretaceous Extinction

Shortly after the end-Cretaceous mass extinction, the earliest known primates, such as Purgatorius mckeeveri shown in the foreground, quickly set themselves apart from their competition -- like the archaic ungulate mammal on the forest floor -- by specializing in an omnivorous diet including fruit found up in the trees.

The end-Cretaceous mass extinction 66 million years ago was characterized by a worldwide ecological catastrophe and rapid species turnover. Arboreal (tree-dwelling) species were especially at risk of extinction due to large-scale devastation of forested environments caused by wildfires from the Chicxulub asteroid impact. New research led by Cornell University and University of Cambridge scientists reveals that most of the surviving mammals did not...

Schematic representation of the key steps of the teleportation protocol and its verification: (1) realization of an EPR source: the Stokes scattering of a pair of nanobeams results in an entangled state between the photon polarization state and the phonon population state in the nanobeams; (2) an arbitrary input state is encoded in the polarization basis of a weak coherent state; (3) a BSM of the polarization teleports the input state onto the joint mechanical memory state; (4) a short anti-Stokes pulse maps the teleported state (ψout) back onto the photon polarization for verification.

Hughes et al. demonstrate an endogenously-generated electric field proportional to the membrane potential Vm, and most likely caused by capacitive coupling between cytoplasm and extracellular medium, which manifests as changes in ζ-potential, low-frequency polarization and surface conductance; significantly, this shows red blood cells can alter the way in which they interact with their surroundings by the membrane potential rather than membrane composition, shedding new light on ion channel activity, cardiovascular disease, and drug action.
