Ecological research, 30 feet down - Jon Witman, professor of biology, photographs an 18-by-24-inch sample of a Caribbean rock wall. He and his team produced and analyzed more than 1,500 such marine images from around the world.
Latitude matters - A photographic sample taken from a ledge off Cape Town, South Africa, is packed with sponges, anemones, soft corals, sea fans and bryzoans, whose name, taken from the Greek, means “moss animals.”
In an epic research project spanning 14 years and seven continents, a research team based at Brown University has photographed and cataloged nearly 3,000 species of sponges, corals and other shallow water ocean invertebrates from Antarctica to Australia. The key finding: Large-scale forces play a pivotal role in local species diversity. Results are published in the current online early edition of the Proceedings of the National Academy of Sciences.
In a groundbreaking, globetrotting study of sea life in shallow waters, a research team led by a Brown University marine ecologist has found that the richness of species diversity in a small patch of ocean is powerfully shaped by far-away forces.
Jon Witman, associate professor of biology at Brown, said this finding was a surprise. At the start of the project, Witman expected to find that forces specific to a small area of ocean – predation, species competition and disturbances such as hurricanes or landslides – would play a central role in limiting the number of species found there.

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...
