Oldest rove beetle in the Omaliini tribe found in French amber

Oldest rove beetle in the Omaliini tribe found in French amber
2014-07-31
(Press-News.org) An international team of scientists from Spain, France, and the U.S. has discovered and described a rove beetle that is the oldest definitive member of the tribe Omaliini that has ever been found in amber. The discovery and description were made possible through the use of the propagation phase-contrast X-ray synchrotron imaging technique, which allows the detailed study of otherwise invisible specimens in opaque amber. The new species is described in the journal Annals of the Entomological Society of America in an article called "Oldest Omaliini (Coleoptera: Staphylinidae: Omaliinae) Discovered in the Opaque Cretaceous Amber of Charentes."

The tribe Omaliini belongs to the subfamily Omaliinae, which belongs to the family Staphylinidae, the largest of all of the beetle families, with more than 60,000 described species.

Two specimens of the "new" species, called Duocalcar geminum, were found in a single piece of opaque amber, along with other arthropods that were embedded in the same piece of amber.

The genus name, Duocalcar, means "two spurs" in Latin, "alluding to the two distinctive projections on each hind leg, at the trochanteral apex and near the tibial apex." The specific epithet, geminum, is a Latin adjective meaning "twin-born," in reference to the discovery of both specimens in the same piece of amber.

"D. geminum is the first Omaliinae described from any amber, increasing the minimum age of Omaliini to ≈100 million years, from Eocene to latest Albian," the authors wrote.

Free pores for molecule transport

Free pores for molecule transport
2014-07-31
This news release is available in German. Metal-organic frameworks (MOFs) can take up gases similar to a sponge that soaks up liquids. Hence, these highly porous materials are suited for storing hydrogen or greenhouse gases. However, loading of many MOFs is inhibited by barriers. Scien-tists of Karlsruhe Institute of Technology (KIT) now report in Nature Communications that the barriers are caused by cor-rosion of the MOF surface. This can be prevented by water-free synthesis and storing strategies. MOFs are crystalline materials consisting of metallic nodes ...

Scientists shine bright new light on how living things capture energy from the sun

2014-07-31
Since Alexandre Edmond Becquerel first discovered the photovoltaic effect in 1839, humankind has sought to further understand and harness the power of sunlight for its own purposes. In a new research report published in the August 2014 issue of the FASEB Journal, scientists may have uncovered a new method of exploiting the power of sunlight by focusing on a naturally occurring combination of lipids that have been strikingly conserved throughout evolution. This conservation—or persistence over time and across species—suggests that this specific natural combination of lipids ...

Misinformation diffusing online

2014-07-31
The spread of misinformation through online social networks is becoming an increasingly worrying problem. Researchers in India have now modeled how such fictions and diffuse through those networks. They described details of their research and the taxonomy that could help those who run, regulate and use online social networks better understand how to slow or even prevent the spread of misinformation to the wider public. Krishna Kumar and G. Geethakumari of the Department of Computer Science and Information Systems, at BITS-Pilani, Hyderabad Campus, in Andhra Pradesh, India, ...

Lead in teeth can tell a body's tale, UF study finds

Lead in teeth can tell a bodys tale, UF study finds
2014-07-31
GAINESVILLE, Fla. – Your teeth can tell stories about you, and not just that you always forget to floss. A study led by University of Florida geology researcher George D. Kamenov showed that trace amounts of lead in modern and historical human teeth can give clues about where they came from. The paper will be published in the August issue of Science of The Total Environment. The discovery could help police solve cold cases, Kamenov said. For instance, if an unidentified decomposed body is found, testing the lead in the teeth could immediately help focus the investigation ...

Scientists discover biochemical mechanisms contributing to fibromuscular dysplasia

2014-07-31
An important step has been made to help better identify and treat those with fibromuscular dysplasia (FMD). FMD causes both an abnormal narrowing and enlarging of medium sized arteries in the body, which can restrict blood flow to the kidneys and other organs causing damage. In a new report appearing in August 2014 issue of The FASEB Journal, scientists provide evidence that that FMD may not be limited to the arteries as currently believed. In addition, they show a connection to abnormalities of bones and joints, as well as evidence that inflammation may be driving the ...

New paper describes how DNA avoids damage from UV light

2014-07-31
BOZEMAN, Mont. – In the same week that the U.S. surgeon general issued a 101-page report about the dangers of skin cancer, researchers at Montana State University published a paper breaking new ground on how DNA – the genetic code in every cell – responds when exposed to ultraviolet (UV) light. The findings advance fundamental understanding of DNA damage by the UV rays found in sunlight. This damage can lead to skin cancer, aging and some degenerative eye diseases. "Our paper advances foundational knowledge about how DNA responds to UV radiation. In our experiments, ...

Magnetic resonance imaging in patients with transient ischemic attack

2014-07-31
Transient ischemic attack (TIA) is a temporary event, which portends a higher risk of a disabling stroke following the TIA. However, the evaluation and management of TIA vary worldwide and is debated and controversial. Dr. Mohamed Al-Khaled from University of Lübeck in Germany considered With the development of brain imaging, particularly diffusion weighted imaging-magnetic resonance imaging (DWI-MRI), the diagnosis of TIA changed from time-based definition to a tissue-based one. DWI-MRI became a mandatory tool in the TIA workup. The DWI-MRI provides not only the evidence ...

Ligaments disruption: A new perspective in the prognosis of SCI

2014-07-31
Worldwide prevalence of Spinal Cord Injury (SCI) is ranging from 233 to 755 per million inhabitants, whereas reported incidence lies between 10.4 and 83 per million inhabitants per year. Thus, the socioeconomic impact of SCI associated with cervical trauma is high enough to be encountered within one of the most important worries in vast majority of developed countries. The ability to predict recovery following SCI is of paramount importance to the physician's role in providing the best care and guidance to patients and families during the illness. Diagnosis of cervical ...

Brother of Hibiscus is found alive and well on Maui

Brother of Hibiscus is found alive and well on Maui
2014-07-31
Most people are familiar with Hibiscus flowers- they are an iconic symbol of tropical resorts worldwide where they are commonly planted in the landscape. Some, like Hawaii's State Flower- Hibiscus brackenridgei- are endangered species. Only a relatively few botanists and Hawaiian conservation workers, however, are aware of an equally beautiful and intriguing related group of plants known as Hibiscadelphus- literally "brother of Hibiscus". Brother of Hibiscus species are in fact highly endangered. Until recently only one of the seven previously known species remained ...

Singing the same tune: Scientists develop novel ways of separating birdsong sources
2014-07-31
Researchers at the University of California, Los Angeles and the Chinese Academy of Sciences have pioneered a new study that could greatly improve current methods of localising birdsong data. Their findings, which ascertain the validity of using statistical algorithms to detect multiple-source signals in real time and in three-dimensional space, are of especial significance to modern warfare. Recently published in the journal Unmanned Systems, the study demonstrates the validity of using approximate maximum likelihood (AML) algorithms to determine the direction of arrival ...
