NOAA Fisheries Service published with the Federal Register today a proposed rule to list black abalone, a marine mollusk coveted by fishermen and gourmets alike, as endangered under the Endangered Species Act (ESA). The proposal comes after NOAA Fisheries Service considered the report of a scientific review team concluding that the species is at risk of extinction.
“The scientific review team reported major declines in the population of black abalone, especially in the areas around the Channel Islands off Southern California,” said Rod McInnis, Southwest Regional Administrator for NOAA’s National Marine Fisheries Service. “These proposed regulations seek federal protection for black abalone and request input from the public in determining what areas might be included as critical habitat for the species.”
Black abalone were once plentiful in the intertidal waters from Northern Baja California, Mexico, to Monterey, Calif., although there is some scientific debate about how far north the population once extended. The species was utilized by early California natives and peaked as a commercial fishery in the state in 1973 with almost two million pounds harvested.
Since the 1980s, black abalone abundance has plummeted primarily from a bacterial disease known as withering syndrome. Other causes of the rapid population decline are likely due to historical overfishing, poaching and natural predation. NMFS has considered recent preliminary evidence which suggests a small disease resistant population may exist at San Nicolas Island. Even with this possibility, the likelihood that black abalone populations will continue to decline towards extinction (within the next 30 years) is very high.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
