Music students do better in school than non-musical peers

Eurekalert.org 

High school students who take music courses score significantly better on math, science and English exams than their non-musical peers, according to a new study published in the Journal of Educational Psychology.

Ruminants' genes are a treasure trove

Eurekalert.org 

A new large-scaled research project has mapped the genome of 44 ruminant species -- a group of animals that have intrigued researchers for years because of their biological diversity and their huge importance as domestic animals.

Study ties poor sleep to reduced memory performance in older adults

Eurekalert.org 

A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and older African American research participants.

Hydrogel offers double punch against orthopedic bone infections

Eurekalert.org 

Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved. Now, researchers have a developed a double-duty hydrogel that both attacks the bacteria and encourages bone regrowth with a single application containing two active components.

Play games with no latency

Eurekalert.org 

One of the most challenging issues for game players looks to be resolved soon with the introduction of a zero-latency gaming environment. A KAIST team developed a technology that helps game players maintain zero-latency performance. The new technology transforms the shapes of game design according to the amount of latency.

Helping the body's ability to grow bone

Eurekalert.org 

For the first time, scientists have been able to study how well synthetic bone grafts stand up to the rigors and 'strains' of life, and how quickly they help bone re-grow and repair.



Study investigates role of family doctors in advanced therapies

Eurekalert.org 

A group of researchers at the University of Granada has conducted a study into the knowledge and attitudes of Family Medicine residents, in relation to the so-called 'advanced therapies'. These include gene therapy, cell therapy, and tissue engineering.

A wearable vibration sensor for accurate voice recognition

Eurekalert.org 

Professor Kilwon Cho of Chemical Engineering and Professor Yoonyoung Chung of Electronic and Electric Engineering from POSTECH successfully developed a flexible and wearable vibration responsive sensor. When this sensor is attached to a neck, it can precisely recognize voice through vibration of the neck skin and is not affected by ambient noise or the volume of sound.

Shedding light on rhodopsin dynamics in the retina

Eurekalert.org 

Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Emeritus Professor Fumio Hayashi of Kobe University and his colleagues revealed that the photoreceptor protein rhodopsin forms transient clusters within the disc membranes in retina. These clusters are concentrated in the center of disc membranes, and act as platforms in the process of light to chemical signal conversion.

How to bend waves to arrive at the right place

Eurekalert.org 

Under certain circumstances, a wave can split into several paths, reaching some places with high intensity, while avoiding others almost completely. This kind of 'branched flow' has first been observed in 2001. Scientists at TU Wien (Vienna) have now developed a method to exploit this effect. The core idea of this new approach is to send a wave signal exclusively along one single pre-selected branch, such that the wave is hardly noticeable anywhere else.

Novel Chinese nanogenerator takes cue from electric eels

Eurekalert.org 

Researchers from the Beijing Institute of Nanoenergy and Nanosystems and the University of Chinese Academy of Sciences have developed a bionic stretchable nanogenerator (BSNG) that takes inspiration from electric eels.

Non-invasive view into the heart

Eurekalert.org 

The non-invasive measurement of blood flow to the heart using magnetic resonance imaging (MRI) is on par with cardiac catheterization. This was the result of an international study published in the current issue of the New England Journal of Medicine and headed by researchers from Goethe University.

A solarium for hens? How to increase the vitamin D content of eggs

Eurekalert.org 

Many people suffer from a vitamin D deficiency. This can result in brittle bones and an increased risk of respiratory diseases. Chicken eggs are a natural source of vitamin D and one way to, at least partially, compensate for this deficiency. A team of nutritionists and agricultural scientists at Martin Luther University Halle-Wittenberg (MLU) has found a new way to further increase the vitamin D content of eggs: by exposing chickens to UV light.

Researchers unveil how soft materials react to deformation at molecular level

Eurekalert.org 

Before designing the next generation of soft materials, researchers must first understand how they behave during rapidly changing deformation. In a new study, researchers challenged previous assumptions regarding polymer behavior with newly developed laboratory techniques that measure polymer flow at the molecular level.

More energy needed to cope with climate change

Eurekalert.org 

A new study published today in Nature Communications by researchers from IIASA, Boston University, and the Ca' Foscari University of Venice found that by mid-century climate change will increase the demand for energy globally, even with modest warming.
