New research into how biodiversity is generated and maintained in the seas surrounding hostile Polar Regions is reported in this month`s Proceedings of the Royal Society (Biological Sciences).
British Antarctic Survey biologist David Barnes studied `battles` between rock-dwelling marine organisms in shallow seas from the Poles to tropics to come up with a `league table` and a `polar pecking order` that lead to a greater understanding of extreme environments and how marine organisms may react to global change.
Barnes found that the battle for survival in the shallow seas surrounding the Polar Regions is much tougher than in the tropics. Not only must small aquatic animals (Bryozoa) compete for space to get food, they also have to contend with massive destruction of their habitat by icebergs and rough seas. However, by a strange twist of fate, these harsh conditions appear to increase biodiversity.

Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
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...
