Weak magnetic and electromagnetic fields affect physiological processes in animals, plants, and microorganisms. Ion cyclotron resonance (ICR) is discussed as one of the sensitive mechanisms, which enable perception of the geomagnetic field and its or

Seawater is the major heat transporter in our global environment, covering more than two-thirds of the surface of the earth. With an average salinity of ∼3.5%, it is a moderate electric conductor, which is permanently in motion by thermal and hydro

The mode of carotenoid (Crt) binding to polypeptide and specifying its function is as yet largely unknown. Statistical analysis of major photosystems I and II suggests that aromatic residues make up a significant part of the Crt binding pockets. Phen

The ability to respond to magnetic fields is ubiquitous among the five kingdoms of organisms. Apart from the mechanisms that are at work in bacterial magnetotaxis, none of the innumerable magnetobiological effects are as yet completely understood in

This article reviews phenomena of magnetoreception in plants and provides a survey of the relevant literature over the past 80 years. Plants react in a multitude of ways to geomagnetic fields-strong continuous fields as well as alternating magnetic f

Black lipid membranes were prepared on a Teflon septum separating electrically the two chambers of a Teflon cuvette, using the technique of Mueller et al., (Nature 194. 979 (1962)). An external, static magnetic field was applied, whose intensity vari

Liquid cultures of Chlorella kessleri, Scenedesmus armatus and Chlamydomonas reinhardtii have been grown phototrophically in weak (0 .2 -2 G) alternating (7.8 Hz) magnetic fields. The data indicate, that the rate of cell division is larger at 0.2 tha

Correlations between geomagnetic-field and climate parameters have beensuggested repeatedly, but possible links are controversially discussed.Here we test if weak (Earth-strength) magnetic fields can affectclimatically relevant properties of seawater

Background The effects of weak magnetic and electromagnetic fields in biology have been intensively studied on animals, microorganisms and humans, but comparably less on plants. Perception mechanisms were attributed originally to ferrimagnetism, but

Biological effects of weak magnetic fields are widespread, but poorly understood. Besides magnetic particles, which have been shown to be involved in only few cases, membranes are discussed as the site of perception. However, the mechanism is unknown
