A team of Texas A&M University and Louisiana State University scientists conducted a research cruise in late August to the "dead zone" - a region in the northern Gulf of Mexico that suffers from low oxygen and results in huge marine losses - and much to their surprise, the "dead zone" area had either moved or had disappeared completely.
Steven DiMarco, associate professor in the Department of Oceanography and leader of the team, found that some areas that were previously hypoxic - a technical term for extremely low dissolved oxygen concentrations in water - had broken up and appeared to pose little threat to marine life, while in other areas the hypoxia appeared to have moved further off shore.
Hypoxia can result in fish kills and can adversely affect many types of marine life where it is present. The dead zone area encompassed more than 6,000 square miles this year. "We found that the hypoxia had moved offshore from shallow waters to much deeper waters in the Gulf," DiMarco explains. "In other words, much of the dead zone had broken up, and this very much surprised us."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
