“Cold-Water Coral Mounds Revealed” is authored by members of the IODP Expedition 307 Porcupine Basin Carbonate Mounds science party. A second article, “Continental Break-Up and Sedimentary Basin Formation,” discusses strategic planning for future investigations into continental break-up and rifting that took root at an IODP international workshop recently held in Pontresina, Switzerland.
The coral mounds report discusses deep-ocean coring along the Irish Continental Margin, 150 kilometers off the shores of southwestern Ireland, where the IODP science party recovered the first complete section through to the base of a modern cold-water coral mound. Since the expedition, studies of the recovered sediment are providing insight into the initiation and growth of these structures, their role as paleoceanographic recorders, and the interpretation of fossil mounds in the geological record. The article is authored by the IODP expedition scientists; lead author is Trevor Williams of Lamont-Doherty Earth Observatory, Columbia University, New York.

The report on the continental break-up and rifting workshop, the precursor to a scientific drilling proposal to IODP, is authored by Millard (Mike) Coffin of the University of Tokyo; Dale Sawyer of Rice University, Houston; Timothy Reston of University of Birmingham, UK; and Joann Stock of the California Institute of Technology, Pasadena. Background on the prospective science investigations that drove the scientists’ workshop is online at http://www.iodp.org/continental-breakup.
The Integrated Ocean Drilling Program (IODP) is an international scientific research program dedicated to advancing scientific understanding of the Earth by monitoring and sampling subseafloor environments. Through multiple platforms, IODP scientists explore the deep biosphere, environmental change, geodynamics and solid earth cycles. Expedition 311, noted above, was managed by the JOI Alliance, the IODP U.S. science operator, aboard the JOIDES Resolution, the U.S.-sponsored scientific research vessel. The IODP 10-year science plan is supported by two lead agencies, the U.S. National Science Foundation and Japan’s Ministry of Education, Culture, Sports, Science, and Technology. Other support comes from the European Consortium on Ocean Research Drilling (ECORD), the People’s Republic of China--Ministry of Science and Technology, and the Republic of Korea. Overall, 21 member nations participate in IODP.

Greenland ice flow likely to speed up: New data assert glaciers move over sediment, which gets more slippery as it gets wetter

Climate change: In their old age, trees still accumulate large quantities of carbon

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
