Researchers evaluate the effects of warm waters on little fish
Warm Caribbean waters may provide a toasty growing area for larval fish, but thats not enough to ensure a flourishing fish population. Thats the conclusion of research published in this months edition of Marine Ecology Progress Series by Dr. Su Sponaugle and colleagues from the University of Miami Rosenstiel School. The scientists studied the petite, yet eye-catching blue-headed wrasse in the upper Florida Keys to monitor larval settlement success.
“The key to any larval reef fishs survival is to find food, avoid predation, and get to a reef to settle,” Sponaugle said. Fish larvae remain at sea for several weeks before returning to the reef to settle and join adult populations. What goes on during this time in the plankton is largely unknown. “What we found is that warm summer waters here are conducive to rapid larval growth, but other factors sometimes interfere, leading to highly variable settlement rates.”

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
