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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
