Atrial fibrillation, the most frequently diagnosed type of irregular heart rhythm, is more prevalent in whites than people from other race or ethnic groups, according to researchers at UC San Francisco. 
Atrial fibrillation is the most common cardiac arrhythmia. People over 40 years of age have a 26 percent lifetime risk of developing this abnormality, according to the Framingham Heart Study.

Researchers have come one step closer to understanding unstable atomic nuclei.

The protons and neutrons inside the atomic nucleus exhibit shell structures in a manner similar to electrons in an atom. For naturally stable nuclei, these nuclear shells fill completely when the number of protons or the number of neutrons is equal to the 'magic' numbers 2, 8, 20, 28, 50, 82 or 126. But not always. For exotic nuclei, 28 is not a magic number of neutrons. Traditional magic numbers, which were once thought to be common for all nuclei, can change in unstable, radioactive nuclei that have a large imbalance of protons and neutrons.

Today I was in the mood of cleaning up some areas of my labyrintic hard drive, after having performed a periodic backup of its contents. I thus came across some pieces of text that had been sitting in a remote folder, waiting to be used for a project now obsolete. I was about to just dump these files in the trash bin, when it occurred to me that this was stuff that had taken me some good time to put together, and maybe there was a better use for it.

A group at the University of Exeter used functional magnetic resonance imaging (fMRI) technology on the brains of 13 volunteers, all faculty members and graduate students in English at the school, to see how they respond to poetry and prose - and then declared that "scientists prove" poetry is like music to the mind.

The upcoming results in the Journal of Consciousness Studies found a "reading network" of brain areas was activated in response to any written material and also that more emotionally charged writing aroused several of the regions in the brain which respond to music. 

A new paper uses mathematical models
to examine the effect of direct and indirect social influences, otherwise known as peer pressure, on how decisions are reached on important issues. The data taken from 15 networks, including groups as disparate as U.S. school superintendents and Brazilian farmers, outline peer pressure's crucial role in society.  

In soccer, football in the rest of the world, a team is most vulnerable right after they score. That is why goals often come in pairs. 

But there is also a more dangerous statistic relating to scoring. Players are at a greater risk of injury five minutes or after a goal has been scored and the frequency of player injuries also increases when their team has the lead, according to a paper that analyzed injuries over the last three World Cup tournaments. 

The Toby Jug Nebula, formally known as IC 2220, is an example of a reflection nebula - a cloud of gas and dust illuminated from within by a star called HD 65750. 

The Toby Jug Nebula is located 1,200 light-years from Earth in the southern constellation of Carina  - The Ship's Keel.

HD 65750, the driver of the nebula, is a red giant, has five times the mass of our Sun and is in a much more advanced stage of its life, despite its comparatively young age of around 50 million years. Stars with more mass run through their lives much more quickly than lighter ones such as the Sun, which have lives measured in billions, rather than millions, of years.

When you think about science leadership, you don't often think about United Arab Emirates. Dictatorships don't lend themselves to quality basic research but when they put their minds to applied research and development, and a lot of money, good things can happen.

While environmental activists wish we were a little more dictatorship-oriented when it comes to banning cars, like the Chinese did before the Olympics (for everyone but elites, anyway), plenty of scientists might like to have a more dictatorial, mission-based approach to research in the US, like we had with the Manhattan Project and the NASA Moon landing.

The Nobel Prize in Chemistry 2013 was awarded jointly to Martin Karplus, Michael Levitt and Arieh Warshel "for the development of multiscale models for complex chemical systems".

While today, chemical modeling is carried out in computers, in the early 1970s that was far more difficult. Chemical reactions occur at lightning speed. In a fraction of a millisecond, electrons jump from one atomic nucleus to the other. Classical chemistry has a hard time keeping up; it is virtually impossible to experimentally map every little step in a chemical process using physical models.

Grey literature in medicine has some valuable insight, according to a new paper. The authors say that clinical trial outcomes are more complete in unpublished reports than in publicly available information.

The results found that publicly available information contained less information about both the benefits and potential harms of an intervention than unpublished data. These findings highlight the importance of recent initiatives, such as the AllTrials initiative, that aim to make clinical trial outcome data publicly available, in order to provide complete and transparent information to help patients and clinicians reach decisions about clinical care.
