Harmful algal blooms, or HABs, can harm fish, birds and even people who are exposed to the toxic algae. HABs come in many forms, including a red tide that regularly affects Florida waters, a brown tide organism, and Pfiestera piscicida, an algae associated with fish kills. Scientists are unsure of exactly what causes the blooms, but a Woods Hole Sea Grant research team may have come up with a way to treat the increasingly common occurrences. Don Anderson and Mario Sengco are testing the use of clay to manage and control HABs. Clay, mixed with seawater, is sprayed over the algal bloom, where it binds with the harmful organisms and sinks to the bottom. In laboratory experiments meant to mimic field conditions, results showed that the clay removed 80 to 90 percent of the toxins in 2-hour treatments.
Korea and Japan have used clay to control HABs periodically. In Korea clay is used mainly in aquaculture operations, which provide about 30 percent of Koreas fish. The concept has not caught on yet in the U.S., mainly due to water quality concerns. The WHOI project uses only native clay types, many of which come from the Florida coast in the Gulf of Mexico. Further research on water quality issues and the future feasibility of clay use to treat HABs is currently taking place.

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...
