Researchers trace flow over long distances
Researchers have discovered a pair of seamounts on the ocean floor that serve as inflow and outflow points for a vast plumbing system that circulates water through the seafloor. The seamounts are separated by more than 30 miles (52 kilometers).
"One big underwater volcano is sucking in seawater, and the water flows north through the rocks of the seafloor and comes out through another seamount," said Andrew Fisher, an associate professor of Earth sciences at the University of California, Santa Cruz.
Scientists have known for decades that enormous quantities of ocean water circulate through the seafloor, flowing through the porous volcanic rock of the upper oceanic crust. In the process, the water extracts large amounts of heat from the crust, which is warmed by the constant flow of heat out of the Earths interior. The mystery has been how the water gets in and out of the crust, most of which is covered by a thick layer of relatively impermeable sediments.

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,...
