Chronic migraine cases are amplified by jawbone disorder, according to research

Fri, 22 Sep 2017 00:00:00 EDT

(Fundação de Amparo à Pesquisa do Estado de São Paulo) A study conducted by researchers in Brazil shows patients with chronic migraine are three times as likely to suffer from severe temporomandibular disorder. Though not a primary cause, the disorder is thought to accentuate and perpetuate sensitivity to pain; therefore, researchers recommend in chronic migraine clinical practice the assessement of the disorder's symptoms.

NYU dentistry study pinpoints role of proteins that produce pearls

Fri, 22 Sep 2017 00:00:00 EDT

(New York University) While it is known that pearls are made of calcium carbonate with an organic matrix core, the role of the proteins modulating the organization of these crystals has, until recently, been unclear. Researchers at NYU Dentistry reported the role of two such proteins that regulate the processes leading up to the formation of pearl.



Enhancing the sensing capabilities of diamonds with quantum properties

Fri, 22 Sep 2017 00:00:00 EDT

(American Institute of Physics) When a nitrogen atom is next to the space vacated by a carbon atom, it forms what is called a nitrogen-vacancy center. Now, researchers have shown how they can create more NV centers, which makes sensing magnetic fields easier, using a relatively simple method that can be done in many labs. They describe their results this week in Applied Physics Letters.



Highest-energy cosmic rays have extragalactic origin

Fri, 22 Sep 2017 00:00:00 EDT

(CNRS) A 50-year-old debate has at last been settled: the highest-energy cosmic rays do not originate in our own Galaxy but in galaxies located tens or even hundreds of millions of light years away. The evidence comes from the Pierre Auger Observatory in Argentina, which has been gathering data since 2004 about these particles that constantly bombard the Earth. The CNRS is the observatory's principal French funding agency.

A global perspective: Can humans mitigate risks associated with natural disasters?

Fri, 22 Sep 2017 00:00:00 EDT

(World Scientific) 'The Handbook of Disaster Risk Reduction & Management' explores climate change and its association with socio-economic development and cultures, particularly in vulnerable communities, and investigates how resilience to disasters can be built. As its title suggests, the focus is on mitigation strategies and policies to reduce and manage the consequences of natural disasters. The handbook covers pre- to post-disaster occurrences from a wide range of perspectives, such as gender and country.



Observatory detects extragalactic cosmic rays hitting the Earth

Fri, 22 Sep 2017 00:00:00 EDT

(University of Chicago) Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high energy cosmic rays -- whether they came from our galaxy or outside the Milky Way.The answer is a galaxy or galaxies far, far away, according to a report published Sept. 22 in Science by the Pierre Auger Collaboration.



Seven exciting studies on membrane technologies explained

Fri, 22 Sep 2017 00:00:00 EDT

(World Scientific) 'Membranes for Gas Separations, Vol. 1' in the World Scientific Series in Membrane Science and Technology: Biological and Biomimetic Applications, Energy and the Environment, addresses the subject of gas separation using membranes. The book is a collection of seven gas-separating membrane technologies' studies. Each chapter of this book is dedicated to a distinctive example of different membrane compositions including inorganic, polymeric, metallic, metal organic framework and composite, which have demonstrated successes in separating several industrially relevant gas mixtures.



700-year-old saint myth has been proven (almost) true

(University of Southern Denmark) Scientists confirm that the age and content of an old sack is in accordance with a medieval myth about Saint Francis of Assisi.



Winter cold extremes linked to high-altitude polar vortex weakening

Fri, 22 Sep 2017 00:00:00 EDT

(Potsdam Institute for Climate Impact Research (PIK)) When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere. A new study finds that these weak states have become more persistent over the past four decades and can be linked to cold winters in Russia and Europe.

Party discipline for jumping genes

Fri, 22 Sep 2017 00:00:00 EDT

(University of Veterinary Medicine -- Vienna) Jumping genes, transposons, are part of the genome of most organisms, aggregated into families and can damage the genome by jumping. How hosts suppress the jumping is well investigated. Why they still can jump has hardly been understood so far. Researchers from Vetmeduni Vienna investigated for the first time in all transposons of the host organism, which properties and host environments facilitate jumping. They showed that family affiliation is more important than position.
