Coral reefs, the rainforests of the sea, feed a large portion of the worlds population, protect tropical shorelines from erosion, and harbor animals and plants with great potential to provide new therapeutic drugs. Unfortunately, reefs are now beset by problems ranging from local pollution and overfishing to outbreaks of coral disease and global warming. Although most scientists agree that reefs are in desperate trouble, they disagree strongly over the timing and causes of the coral reef crisis. This is not just an academic exercise, because different answers dictate different strategies for managers and policymakers intent on saving reef ecosystems. The cover story published this month in Geology helps focus the debate.
A team led by Richard Aronson of the Dauphin Island Sea Lab in Alabama took cores through reef frameworks in Belize to reconstruct the history of the reefs over the past several thousand years. Although some scientists have suggested that reefs began their decline centuries ago due to early overfishing, Aronsons team found that coral populations were healthy and vibrant until the 1980s, when they were killed by disease and high sea temperatures. The research effort was supported by the National Geographic Society, the Smithsonian Institution and the National Science Foundation.
As Aronson points out, "Protecting fish populations is important in its own right, but it wont save the corals. Corals are being killed at an unprecedented rate by forces outside local control. Saving coral reefs means addressing global environmental issues--climate change in particular--at the highest levels of government."

A new indicator for marine ecosystem changes: the diatom/dinoflagellate index

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...
