Music Has Powerful (and Visible) Effects on the Brain
It doesn’t matter if it’s Bach, the Beatles, Brad Paisley or Bruno Mars. Your favorite music likely triggers a similar type of activity in your brain as other people’s favorites do in theirs.
That’s one of the things Jonathan Burdette, M.D., has found in researching music’s effects on the brain.
“Music is primal. It affects all of us, but in very personal, unique ways,” said Burdette, a neuroradiologist at Wake Forest Baptist Medical Center. “Your interaction with music is different than mine, but it’s still powerful.
“Your brain has a reaction when you like or don’t like something, including music. We’ve been able to take some baby steps into seeing that, and ‘dislike’ looks different than ‘like’ and much different than ‘favorite.’”
To study how music preferences might affect functional brain connectivity – the interactions among separate areas of the brain – Burdette and his fellow investigators used functional magnetic resonance imaging (fMRI), which depicts brain activity by detecting changes in blood flow. Scans were made of 21 people while they listened to music they said they most liked and disliked from among five genres (classical, country, rap, rock and Chinese opera) and to a song or piece of music they had previously named as their personal favorite.
Those fMRI scans showed a consistent pattern: The listeners’ preferences, not the type of music they were listening to, had the greatest impact on brain connectivity – especially on a brain circuit known to be involved in internally focused thought, empathy and self-awareness. This circuit, called the default mode network, was poorly connected when the participants were listening to the music they disliked, better connected when listening to the music they liked and the most connected when listening to their favorites.
The researchers also found that listening to favorite songs altered the connectivity between auditory brain areas and a region responsible for memory and social emotion consolidation.

The Cat's Paw Nebula
Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat's Paw Nebula visible in Scorpius. At 5,500 light years distant, Cat's Paw is an emission nebula with a red color that originates from an abundance of ionized hydrogen atoms. Alternatively known as the Bear Claw Nebula or NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. Pictured here is a deep field image of the Cat's Paw Nebula in light emitted by hydrogen, oxygen, and sulfur.

Meme Mora River Falls, Jamberoo, NSW
This 100m (300') fall is in the upper reaches of the Meme Mora (the river of many fish, today anglicized as Minnamurra). It is part of a series of drops that end in a plunge into a deep slot canyon. Access to the falls has been blocked because of dangerous conditions on the upper path.
This is a fast high ISO single shot (the darker of a HDR set), focused on this side of the edge of the fall to catch individual droplets falling on the vegetation on the sides of the cliff. The field of focus excludes the bulk of the falling water, to give the fall itself a soft feel. It has been toned for depth and sharpened for screen.

Rome, Italy, Sep 13, 2017 / 12:08 am (CNA/EWTN News).- For the first time ever, a non-Italian will serve as apostolic nuncio, or papal ambassador, to Italy. On Sept. 12, Pope Francis appointed Swiss-born diplomat Archbishop Emil Paul Tscherrig as his new ambassador to Italy. Archbishop Tscherrig has served most recently as apostolic nuncio to Argentina. Ironically, he was appointed nuncio there in 2012, replacing Archbishop Adriano Bernardini, who had been appointed nuncio to Italy. Four years later, he is called to replace Archbishop Bernardini again. Archbishop Tscherrig is a high-profile diplomat. Born in 1947, the first of eight children of a “Bergbauern” – mountain farmer – family, he was ordained a priest in 1974 and entered the Holy See diplomatic service in 1978. He worked in the Secretariat of State as assistant to Fr. Roberto Tucci, preparing Pope St. John Paul II’s trips outside of Italy. He served in several nunciatures before being appointed a nuncio: in Burundi from 1996 to 2000, in Caribe and Antille from 2000 to 2004, in Korea and Mongolia from 2004 and 2008 and in Scandinavian countries between 2008 and 2012. With his 2012 appointment as nuncio to Argentina, he got to know Cardinal Jorge Bergoglio, who then served as Archbishop of Buenos Aires. While relations have appeared cool between Archbishop Bernardini and Pope Francis, dating to their time in Argentina, Archbishop Tscherrig has long maintained a positive relationship with the Pope. The appointment of a Swiss bishop as Italy’s apostolic nuncio ends the so-called “Italian exception.” Since Italy and Holy See established full diplomatic ties in 1929, nuncios to Italy have always been of Italian nationality. This was an “exception” because the Holy See usually desires that the “Pope’s ambassador” be of a nationality different from that of the country he is appointed to, in order to avoid any “national” influence in diplomatic affairs. Apostolic nuncios have two main obligations: they maintain diplomatic relations between the Holy See and the nation to which they are appointed, and they represent the concerns of the Holy Father toward the local Church, conveying his intentions, and assisting in the appointment of new bishops. The “Italian exception” worked because the nuncio to Italy has focused mainly on the appointment of bishops, while diplomatic and political issues have been managed on the basis of personal relations between officials of the Italian government and those of the Holy See. Recent developments have changed that arrangement. The internationalization of the College of Cardinals, started more than 60 years ago under Pius XII, has become a solid reality – the Church’s cardinals hail from more than 80 different countries. The staff of the Roman Curia – the offices of the Vatican – also has developed an international flavor: top posts and clerical jobs in Vatican offices are more frequently entrusted to non-Italian bishops or priests, though the official language is still the Italian. This change has eroded the natural relationships between the Italian government and the Holy See. The appointment of a Swiss nuncio to Italy now ends the most visible “Italian exception” in the Vatican, and nearly ends the custom of reserving certain Vatican roles for Italians. In fact, there is one remaining exception left for the Italians. There is an unwritten rule in Rome that the Holy See’s Secretary of State must be Italian, if the Pope is not Italian. Until now, this rule has always been followed, with the only exception of Cardinal Jean-Marie Villot, who kept his post as Secretary of State when St. John Paul II was elected. He died March 9, 1979, a few months after St. John Paul II’s election, and was replaced with Cardinal Agostino Casaroli, a very skilled Italian diplomat. Time will tell how long the last remaining “Italian exception” will hold.

When it comes to pain, mind and body are one system.
"Fixing chronic back pain is possible when patients understand how much it is produced by the brain, not the spine. If you wish to get past the terror, you are going to have to follow pain deep into its lair."
--------------------
New hypothesis explains why: persistent back pain with no obvious mechanical source does not always result from tissue damage. Instead, that pain is generated by the central nervous system (CNS) and lives within the brain itself.
-----------------
More than three centuries ago, the French philosopher, mathematician and scientist René Descartes advanced the heretical idea that pain was not a punishment from God, nor a test or trial to be endured, for which prayer was the only intervention. Instead, he said, pain existed as a mechanical response to physical damage. His work Treatise of Man would not be published until after he died (some say because he feared persecution by Christian authorities, for whom the threat of pain was a useful recruitment tool).
----------------------
Historically, NIH has dedicated only 1 per cent of its research budget to pain science-related investigations. And until recently, painkiller manufacturers saw no reason to invest in very speculative research, thus unwisely diluting their shareholders’ earnings. But with opioid treatment on the skids, and profits sinking, finding new therapeutic targets is suddenly very attractive.
----------------------
Drug targets are still on the horizon. But many pain psychologists and rehab specialists believe that central sensitisation can be successfully treated with a combination of cognitive behavioural therapy (CBT) and graded, non-pain-contingent exercise. The good news is that several labs have now shown that, after a patient’s pain has been properly treated, three months of CBT can substantially reverse pain-induced changes in grey matter.
As a practice, CBT provides graded exposure to feared stimuli. That means if you’re afraid of spiders or flying, you dull your terror by facing down the arachnid or the take-off and landing, safely and repetitively. With back-pain patients, the fear of pain might seem life-threatening. This idea is often implanted by healthcare practitioners who caution patients, unnecessarily, to ‘be careful,’ and to ‘spare their backs’. The job is to let patients know that, in the case of chronic back pain, hurt does not typically mean harm.

X-rays Reveal Temperament of Possible Planet-Hosting Stars NASA Chandra | GJ 176: A Sun-like Star More than a Billion Years Old | Artist illustration of of possible planet-hosting stars. | Sept. 6, 2017: A new X-ray study has revealed that stars like the Sun and their less massive cousins calm down surprisingly quickly after a turbulent youth. This result has positive implications for the long-term habitability of planets orbiting such stars.
A team of researchers used data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton to see how the X-ray brightness of stars similar to the Sun behaves over time. The X-ray emission from a star comes from a thin, hot, outer layer, called the corona. From studies of solar X-ray emission, astronomers have determined that the corona is heated by processes related to the interplay of turbulent motions and magnetic fields in the outer layers of a star.
High levels of magnetic activity can produce bright X-rays and ultraviolet light from stellar flares. Strong magnetic activity can also generate powerful eruptions of material from the star’s surface. Such energetic radiation and eruptions can impact planets and could damage or destroy their atmospheres, as pointed out in previous studies, including Chandra work reported in 2011 and 2013.
Since stellar X-rays mirror magnetic activity, X-ray observations can tell astronomers about the high-energy environment around the star. The new study uses X-ray data from Chandra and XMM-Newton to show that stars like the Sun and their less massive cousins decrease in X-ray brightness surprisingly quickly.
Specifically, the researchers examined 24 stars that have masses similar to the Sun or less, and ages of a billion years or older. (For context, the Sun is 4.5 billion years old.) The rapid observed decline in X-ray brightness implies a rapid decline in energetic activity, which may provide a hospitable environment for the formation and evolution of life on any orbiting planets.
“This is good news for the future habitability of planets orbiting Sun-like stars, because the amount of harmful X-rays and ultraviolet radiation striking these worlds from stellar flares would be less than we used to think,” said Rachel Booth, a graduate student at Queen’s University in Belfast, UK, who led the study.
This result is different from other recent work on Sun-like and lower mass stars with ages less than a billion years. The new work shows that older stars drop in activity far more quickly than their younger counterparts.
“We’ve heard a lot about the volatility of stars less massive than the Sun, like TRAPPIST-1 and Proxima Centauri, and how that’s bad for life-supporting atmospheres on their planets,” said Katja Poppenhaeger, a co-author from Queen’s University and the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass. “It’s refreshing to have some good news to share about potential habitability.”
To understand how quickly stellar magnetic activity level changes over time, astronomers need accurate ages for many different stars. This is a difficult task, but new precise age estimates have recently become available from studies of the way that a star pulsates using NASA’s Kepler and ESA’s CoRoT missions. These new age estimates were used for most of the 24 stars studied here.
Astronomers have observed that most stars are very magnetically active when they are young, since the stars are rapidly rotating. As the rotating star loses energy over time, the star spins more slowly and the magnetic activity level, along with the associated X-ray emission, drops.
“We’re not exactly sure why older stars settle down relatively quickly,” said co-author Chris Watson of Queen’s University. “However, we know it’s led to the successful formation of life in at least one case—around our own Sun.”
One possibility is that the decrease in rate of spin of the older stars occurs more quickly than it does for the younger stars. Another possibility is that the X-ray brightness declines more quickly with time for older, more slowly rotating stars than it does for younger stars.
A paper describing these results has been accepted for publication in the Monthly Notices of the Royal Astronomical Society, and is available online. The other co-authors are Victor Silva Aguirre from Aarhus University in Denmark and Scott Wolk from CfA.
