A startling mutual-aid society is linking fungus and snails in marine ecosystems, according to a study led by a Brown University biologist. The study presents the first evidence that a species of marine snail engages in a previously undemonstrated form of food acquisition and ecological control by initiating and encouraging the growth of fungi, its preferred food, on live marsh grass. Infestation by fungi greatly slows the growth of the grass.
In surveys conducted along 2,000 kilometers of salt marshes on the southern U.S. shoreline, the researchers observed that the snail, Littoraria irrorata, actively grazes a live salt-marsh cordgrass. As the snail crawls along the grass surface, it scrapes grass tissue with its band of saw-like teeth and creates longitudinal cuts in leaf surfaces, making a much larger meal possible. While it travels, the snail also deposits feces laden with fungal spores and nutrients into the sensitive inner-tissue of the leaf, effectively stimulating and fertilizing fungal crops.
The result of snail grazing on marsh grass surface is an infestation of fungi, a major diet component for the snail, and the slowing of marsh grass growth.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
