A recent study of coral formations in different tropical locations will be used to help geologists reconstruct climate and storm patterns of the past and learn more about the preservation of reefs. The findings will be presented by David Meyer, University of Cincinnati professor of geology, at the upcoming 2002 meeting and exposition of the Geological Society of America.
Meyer’s previous research established that coral reefs can be an index of the ocean’s health and are greatly impacted by pollution. The report he will deliver at this year’s GSA meeting describes how hurricanes affect coral formations and will help scientists compare modern storm effects to those of the past.
Meyer conducted the research with Benjamin Greenstein of Cornell College in Mt. Vernon, Iowa, and recent UC graduate Jill Bries. The trio’s work investigated the effect that the frequency of hurricanes had on the geological record contained in coral reefs. In high-frequency hurricane areas like the Bahamas and Florida Keys, coral formations were damaged and broken. Meyer described it "like a forest fire going through." Reefs studied in the southern Caribbean islands of Curacao and Bonaire were well preserved owing to a very low frequency of storms.

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...
