The potential of artificial hideouts, outfitted with magnets or their imitations (control), to attract spinycheek crayfish Orconectes limosus was studied. The experiments were carried out within 1999-2002 in an 80-hectar natural lake.

Ferromagnetic material in the eastern red-spotted newt notophthalmus viridescens [PDF]
Behavioral results obtained from the eastern red-spotted newt (Notophthalmus viridescens) led to the suggestion of a hybrid homing system involving inputs from both a light-dependent and a non-light-dependent mechanism. To evaluate the possible role of a

Quantum probe and design for a chemical compass with magnetic nanostructures
Magnetic fields as weak as Earth's may affect the outcome of certain photochemical reactions that go through a radical pair intermediate. When the reaction environment is anisotropic, this phenomenon can form the basis of a chemical compass and has been ...

Stochastic Dynamics of Magnetosomes in Cytoskeleton
Rotations of microscopic magnetic particles, magnetosomes, embedded into the cytoskeleton and subjected to the influence of an ac magnetic field and thermal noise are considered.

Magnetite-based magnetoreception in birds: the effect of a biasing field and a pulse on migratory behavior [PDF]
To test the hypothesis that single domain magnetite is involved in magnetoreception, we treated Australian silvereyes Zosterops l. lateralis with a strong, brief pulse designed to alter the magnetization of single domain particles.

Quantum calcium-ion interactions with EEG
Previous papers have developed a statistical mechanics of neocortical interactions (SMNI) fit to short-term memory and EEG data. Adaptive Simulated Annealing (ASA) has been developed to perform fits to such nonlinear stochastic systems.

Electron spin relaxation can enhance the performance of a cryptochrome-based magnetic compass sensor
The radical pair model of the avian magnetoreceptor relies on long-lived electron spin coherence. Dephasing, resulting from interactions of the spins with their fluctuating environment, is generally assumed to degrade the sensitivity of this compass to ...

Is It Possible to Predict Strong Earthquakes?
The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent ...

Magnetism, FeS colloids, and Origins of Life
A number of features of living systems: reversible interactions and weak bonds underlying motor-dynamics; gel-sol transitions; cellular connected fractal organization; asymmetry in interactions and organization; quantum coherent phenomena; to name some ...
