Quake hits pandas
at the interface between biology, biochemistry and physics raised concerns that the slicing up of the organisation into disciplines might discourage such interdisciplinary work and make it harder to obtain funding for it. SLR cofounder and spokesman Alain Trautmann, head of the department of cellular biology at the Institut Cochin at Paris, expressed doubts that the plans will really amount to ...
متن کاملQuake warnings, seismic culture.
ince 1990, nearly one million people have died from the impacts of earthquakes. Reducing those impacts requires building a local seismic culture in which residents are aware of earthquake risks and value efforts to mitigate harm. Such efforts include earthquake early warning (EEW) systems that provide seconds to minutes notice of pending shaking. Recent events in Mexico provide an opportunity t...
متن کاملAtmospheric Neutrinos and the Oscillations Bonanza
We are lucky, you and I, to be born here on planet Earth and to have as our birthright the unrestricted use of a splendid neutrino beamline. Truly remarkable is that the originating hadronic primary beam, namely the cosmic ray flux of protons and assorted stable nuclei, is isotropic to high degree. Moreover, the beamline target region, which is the terrestrial atmosphere, is very nearly spheric...
متن کاملAtmospheric Neutrinos and the Oscillations Bonanza
New observations with atmospheric neutrinos from the underground experiments SuperKamiokande, Soudan 2, and MACRO, together with earlier results from Kamiokande and IMB, are reviewed. The most recent observations reconfirm aspects of atmospheric flavor content and of zenith angle distributions which appear anomalous in the context of null oscillations. The anomalous trends, exhibited with high ...
متن کاملT-QUAKE Quantum Mechanical Microchip
Delivering quantum-encoded secret keys is known as Quantum Key Distribution, or QKD; in essence it involves transmitting a series of randomly generated, quantum-encoded bits of information between a sender and a receiver, Alice and Bob, over a distance. This string of bits, called qubits, becomes the secret key Alice and Bob use to interpret encoded messages sent over less-secure channels. In t...
