The lost discipline of life-long learning.
“That I, whose experience of teaching is extremely limited, should presume to discuss education is a matter, surely, that calls for no apology. It is a kind of behavior to which the present climate of opinion is wholly favorable. Bishops air their opinions about economics; biologists about metaphysics; inorganic chemists, about theology; the most irrelevant people are appointed to highly techni...
متن کاملMolecular evolution: Actin's long lost relative found
The bacterial protein MreB has been identified as a prokaryotic homolog of the eukaryotic cytoskeletal protein actin. While we still know little about MreB's function, the structural similarities and differences between MreB and actin provide more insight into the remarkable properties of actin.
متن کاملNaChBac: The Long Lost Sodium Channel Ancestor
In excitable cells, the main mediators of sodium conductance across membranes are voltage-gated sodium channels (Na(V)s). Eukaryotic Na(V)s are essential elements in neuronal signaling and muscular contraction and in humans have been causally related to a variety of neurological and cardiovascular channelopathies. They are complex heavily glycosylated intrinsic membrane proteins present in only...
متن کاملMarine reserves reestablish lost predatory interactions and cause community changes in rocky reefs.
In the last decades, marine reserves have dramatically increased in number worldwide. Here I examined the potential of no-take marine reserves to reestablish lost predatory interactions and, in turn, cause community-wide changes in Mediterranean rocky reefs. Protected locations supported higher density and size of the most effective fish preying on sea urchins (the sea breams Diplodus sargus an...
متن کاملMultiple Stressors on Coral Reefs: A Long-Term Perspective
Coral reefs are subject to a high frequency of recurrent biological and physical disturbances. The temporal and spatial scales of these are often large and difficult to study, so that most of our knowledge of disturbances on coral reefs comes from investigations conducted at one or a few sites, over short periods of time. We argue that studying single events in isolation can be misleading and t...
