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

EurekAlert! - Jue, 09/21/2017 - 22:00
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.

NASA'S OSIRIS-REx spacecraft slingshots past Earth

EurekAlert! - Jue, 09/21/2017 - 22:00
NASA's asteroid sample return spacecraft successfully used Earth's gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August.

Study finds no-tillage not sufficient alone to prevent water pollution from nitrate

EurekAlert! - Jue, 09/21/2017 - 22:00
A new IUPUI study funded by the US Department of Agriculture answers a long-debated agricultural question: whether no-tillage alone is sufficient to prevent water pollution from nitrate. The answer is no.

Researchers describe mechanism that underlies age-associated bone loss

EurekAlert! - Jue, 09/21/2017 - 22:00
A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Researchers have now detailed an underlying mechanism leading to that osteoporosis. When this mechanism malfunctions, progenitor cells stop creating bone-producing cells, and instead create fat cells. Knowledge of this mechanism can provide targets in the search for novel bone-loss.

UTA study finds public-private partnerships key to making telemedicine sustainable

EurekAlert! - Jue, 09/21/2017 - 22:00
RadhaKanta Mahapatra, a professor in the Department of Information Systems and Operations Management in the UTA College of Business, conducted the study, A Collaborative Approach to Creating ICT-based Sustainable Development, which was published as part of the Americas Conference on Information Systems' proceedings earlier this year. ICT is Information and Communication Technology. Former Odisha Chief Secretary Sahadeva Sahoo co-authored the study.

Two Group A Streptococcus genes linked to 'flesh-eating' bacterial infections

EurekAlert! - Jue, 09/21/2017 - 22:00
Group A Streptococcus bacteria cause illnesses ranging from mild nuisances like strep throat to life-threatening conditions such as flesh-eating disease, also known as necrotizing fasciitis. Life-threatening infections occur when the bacteria spread underneath the surface of the skin or throat and invade the underlying soft tissue. Researchers have found two group A Streptococcus genes involved in invasive infections, which may be potential targets for therapeutics.

Twitter bots for good: USC ISI study reveals how information spreads on social media

EurekAlert! - Jue, 09/21/2017 - 22:00
Twitter bots have earned a bad reputation -- but not all bots are bad, suggests a new study co-authored by Emilio Ferrara, a USC Information Sciences Institute computer scientist and a research assistant professor at the USC Viterbi School of Engineering's Department of Computer Science with a team from the Technical University of Denmark.

From galaxies far far away!

EurekAlert! - Jue, 09/21/2017 - 22:00
In a paper to be published in Science on 22 September, the Pierre Auger Collaboration reports observational evidence demonstrating that cosmic rays with energies a million times greater than that of the protons accelerated in the Large Hadron Collider come from much further away than from our own Galaxy.

Fires in Australia pop up in places already burned

EurekAlert! - Jue, 09/21/2017 - 22:00
Fires that span across the Northern Territory and Western Australia appear to have broken out in areas that have already been burned in previous fires.

Emergency contraception not as accessible as it should be, says CU Anschutz study

EurekAlert! - Jue, 09/21/2017 - 22:00
Efforts to remove barriers to accessing emergency contraception (EC) scored victories in 2013, when the US Food and Drug Administration removed age restrictions on over-the-counter sales of the levonogestrel drug Plan B.

NYU dentistry study pinpoints role of proteins that produce pearls

EurekAlert! - Jue, 09/21/2017 - 22:00
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.

UCI scientists identify important aspect of the brain's navigational system

EurekAlert! - Jue, 09/21/2017 - 22:00
The ability to successfully navigate in the environment is essential both for animals searching for food or escaping predators, as well as for human urban dwellers. It is something we take for granted, but under the hood, it is supported by still incompletely understood brain networks that continuously calculate our position in the environment. Moreover, the location where certain experience occurred is an indispensable building block of memory.

Discovery of a new genetic syndrome which predisposes the body to cancer

EurekAlert! - Jue, 09/21/2017 - 22:00
A new syndrome caused by biallelic mutations -- those produced in both gene copies inherited from the mother and father -- in the FANCM gene predisposes the body to the appearance of tumors and causes rejection to chemotherapy treatments. Contrary to what scientists believed, the gene does not cause Fanconi anaemia. Researchers recommend modifying the clinical monitoring of patients with these mutations.

Enhancing the sensing capabilities of diamonds with quantum properties

EurekAlert! - Jue, 09/21/2017 - 22:00
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.

Low screening rates for adolescents diagnosed with PID in the nation's emergency departments

EurekAlert! - Jue, 09/21/2017 - 22:00
The nation's emergency departments had low rates of complying with recommended HIV and syphilis screening for at-risk adolescents, though larger hospitals were more likely to provide such evidence-based care.

Highest-energy cosmic rays have extragalactic origin

EurekAlert! - Jue, 09/21/2017 - 22:00
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.

NASA tracking Hurricane Maria on Bahamas approach

EurekAlert! - Jue, 09/21/2017 - 22:00
NASA-NOAA's Suomi NPP satellite provided a look at Maria's temperatures to find the strongest sides of the storm, while NOAA's GOES satellite revealed the extent of the storm in a visible image as it moved toward the Bahamas.

Families of survivors of ECMO for heart conditions report favorable quality of life

EurekAlert! - Jue, 09/21/2017 - 22:00
One of the few large studies to report long-term outcomes in cardiac patients treated in childhood with extracorporeal membrane oxygenation (ECMO) has found overall favorable outcomes among survivors, as reported by families. ECMO provides short-term breathing and heart support for critically ill children while doctors treat the underlying illness.

NASA's Terra satellite sees a very stubborn post-Tropical Cyclone Jose

EurekAlert! - Jue, 09/21/2017 - 22:00
Jose continues to bring tropical storm conditions to southern New England although the storm has become post-tropical. NASA's Terra satellite caught a view of the storm sitting almost stationary about 100 miles from Nantucket Island, Mass.
