Four centuries of history, imitation played a role in modern violin design
Scientist discovers basis of evolution in violins

(Press-News.org) Four families likely influenced violin shape over four centuries, with many imitating famous designs like Stradivarius, according to a study published October 8, 2014 in the open-access journal PLOS ONE by Daniel Chitwood from Donald Danforth Plant Science Center in Missouri.
The first violins appeared in 16th century Italy and since then, their designers have continued to incorporate numerous innovations to improve the acoustical properties and playability of violins. However, details of the body outline can vary without significantly compromising sound quality and may instead reflect other factors, like history. To better characterize the history of the violin, how its shape has changed over time, and how its shape compares among different violin makers, the author of this study analyzed the evolution of the violin shape by family, sampling the body shapes from photographs of over 9,000 instruments over 400 years of history.
Specific shape features, produced by different violin makers, strongly correlate with historical time. Specifically, violin shapes originating from multi-generational luthier families tend to cluster together, and familial origin is a significant explanatory factor of violin shape. The four major clusters include Maggini, Stradivari, Amati, and Stainer. The clustering suggests that luthiers likely copied the outlines of their instruments from others, which historical accounts corroborate. Together, the analysis of four centuries of violin shapes demonstrates not only the influence of history and time leading up to the design of the modern violin, but widespread imitation and the transmission of design by human relatedness.
Daniel Chitwood added, "Shape is information that tells us a story and can inform us about the historical forces shaping our lives and creativity. In the case of violins, their architecture was influenced by consumer preference and resulted in mimicry between violin makers, as well as by genetic lineages and human relatedness, through which information, in the form of shape, passed from one generation to the next."

The discovery of new bones from a large land mammal that lived about 48 million years ago has led scientists to identify a new branch of mammals closely related to modern horses, rhinos, and tapirs, according to a study published October 8, 2014 in the open-access journal PLOS ONE by Lisa Noelle Cooper from Northeast Ohio Medical University and colleagues.
This family of large mammals, Anthracobunidae, is only known from India and Pakistan and was commonly considered to be ancestors of modern elephants and sea cows. Geographically, this was a puzzling idea, because elephants ...

Healthier foods and beverages have been consistently more expensive than unhealthier ones from 2002-2012, with a gap that's growing, according to a study published October 8, 2014 in the open-access journal PLOS ONE by Nicholas Jones from University of Cambridge, UK, and colleagues.
Governments have identified access to affordable healthy diets as a key factor in improving public health, yet methods for tracking prices of more and less healthy foods over time have not been established. The authors of this study analyzed existing government data on national food prices ...

For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.
In January 2013 a Swedish arm amputee was the first person in the world to receive a prosthesis with a direct connection to bone, nerves and muscles. An article about this achievement and its long-term stability will now be published in the Science Translational Medicine journal.

CLEVELAND—Even before he lost his right hand to an industrial accident 4 years ago, Igor Spetic had family open his medicine bottles. Cotton balls give him goose bumps.
Now, blindfolded during an experiment, he feels his arm hairs rise when a researcher brushes the back of his prosthetic hand with a cotton ball.
Spetic, of course, can't feel the ball. But patterns of electric signals are sent by a computer into nerves in his arm and to his brain, which tells him different. "I knew immediately it was cotton," he said.
That's one of several types of sensation ...

A new study, published today in the journal PLOS One, tracked the price of 94 key food and beverage items from 2002 to 2012. Its findings show that more healthy foods were consistently more expensive than less healthy foods, and have risen more sharply in price over time.
Food prices in the UK have risen faster than the price of other goods in recent years, and this new research shows that the increase has been greater for more healthy foods, making them progressively more expensive over time.
While less healthy foods had a slightly greater price rise relative to ...

Berkeley — Fad diets come and go, but might there be something to the ones that involve consuming grapefruit and grapefruit juice? New research at the University of California, Berkeley, suggests that a closer look at grapefruit juice is warranted.
A new study, to be published Wednesday, Oct. 8, in the peer-reviewed journal PLOS ONE, found that mice fed a high-fat diet gained 18 percent less weight when they drank clarified, no-pulp grapefruit juice compared with a control group of mice that drank water. Juice-drinking mice also showed improved levels of glucose, ...

Cut off by freeways and human development, mountain lions in southern California are facing a severe loss of genetic diversity, according to a new study led by the University of California, Davis in partnership with The Nature Conservancy.
The study, published today in the journal PLOS ONE, represents the largest genetic sampling of mountain lions, or pumas, in southern California. It raises concerns about the current status of mountain lions in the Santa Ana and Santa Monica mountains, as well as the longer-term outlook for mountain lions across southern California.

Plant scientists are working to improve important food crops such as rice, maize, and beans to meet the food needs of a growing world population. However, boosting crop output will require improving more than what can be seen of these plants above the ground. Root systems are essential to gathering water and nutrients, but understanding what's happening in these unseen parts of the plants has until now depended mostly on lab studies and subjective field measurements.
To address that need, researchers from the Georgia Institute of Technology and Penn State University have ...

Lebanon, NH, 10/8/14 —To reduce false positives when identifying genetic variations associated with human disease through genome-wide association studies (GWAS), Dartmouth researchers have identified nine traits that are not dependent on P values to predict single nucleotide polymorphisms (SNP) reproducibility as reported in Human Genetics on October 2, 2014.
Reproducibility rates of SNPs based solely on P values is low. Dartmouth authors' analysis of GWAS studies published in Nature Genetics showed a 1-5 percent replication rate.
"It is important to improve our ...

A new study from UCLA found that a drug being evaluated to treat an entirely different disorder helped slow the progression of Parkinson's disease in mice.
The study, published in the October edition of the journal Neurotherapeutics, found that the drug, AT2101, which has also been studied for Gaucher disease, improved motor function, stopped inflammation in the brain and reduced levels of alpha-synuclein, a protein critically involved in Parkinson's.
Although the exact cause of Parkinson's is unknown, evidence points to an accumulation of alpha-synuclein, which has ...
