The restoration of a 2,000-year-old bronze sculpture of the famed ancient Greek athlete Apoxyomenos may help modern scientists understand how to prevent metal corrosion, discover the safest ways to permanently store nuclear waste, and understand other perplexing problems.
That's the conclusion of a new study on the so-called "biomineralization" of Apoxyomenos appearing in the current issue of ACS' Crystal Growth & Design, a bi-monthly journal. Best known as "The Scraper," the statue depicts an athlete scraping sweat and dust from his body with a small curved instrument.
In the report, Davorin Medakovic and colleagues point out that Apoxyomenos was discovered in 1998 on floor of the Adriatic Sea. While the discovery was a bonanza for archaeologists and art historians, it also proved to be an unexpected boon to scientists trying to understand biomineralization. That's the process in which animals and plants use minerals from their surroundings and form shells and bone. Apoxyomenos was encrusted with such deposits.
"As studies of long-term biofouled manmade structures are limited, the finding of an ancient sculpture immersed for two millennia in the sea provided a unique opportunity to probe the long-term impact of a specific artificial substrate on biomineralizng organisms and the effects of biocorrosion," the report said. By evaluating the mineral layers and fossilized organisms on the statue, the researchers were able to evaluate how underwater fouling organisms and communities interacted with the statue as well as how certain mineral deposits on the bronze sculpture slowed its deterioration.ARTICLE #3 FOR IMMEDIATE RELEASE

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...
