Not such a flutter
For many conservationists, butterflies are some of the key species that can indicate the quality of an environment not only for themselves but for many other, often less visible, species. Some of their specific needs are often well known, but movements around their habitat and important factors within it are less understood. To help address this issue, a new study reports for the first time the...
متن کاملChronic cough--not such a heartsink.
P atients present with symptoms. Doctors are trained to recognise disease. There is no better illustration of these two different paradigms than cough. Unfortunately for the patient, the sensory input triggering the cough reflex may arise from anywhere in the territory of the vagus nerve. Thus, chronic cough may be caused by conditions treated by at least three different specialists—the ENT sur...
متن کاملDefending continuous variable teleportation: Why a laser is a clock, not a quantum channel
It has been argued [T. Rudolph and B.C. Sanders, Phys. Rev. Lett. 87, 077903 (2001)] that continuous-variable quantum teleportation at optical frequencies has not been achieved because the source used (a laser) was not ‘truly coherent’. Van Enk, and Fuchs [Phys. Rev. Lett, 88, 027902 (2002)], while arguing against Rudolph and Sanders, also accept that an ‘absolute phase’ is achievable, even if ...
متن کاملScaffolding Proteins: Not Such Innocent Bystanders
Sequential transfer of information from one enzyme to the next within the confines of a protein kinase scaffold enhances signal transduction. Though frequently considered to be inert organizational elements, two recent reports implicate kinase-scaffolding proteins as active participants in signal relay.
متن کاملInterval timing: memory, not a clock.
Anticipation of periodic events signalled by a time marker, or interval timing, has been explained by a separate pacemaker-counter clock. However, recent research has added support to an older idea: that memory strength can act as a clock. The way that memory strength decreases with time can be inferred from the properties of habituation, and the underlying process also provides a unified expla...
