Here is what I am reading today:
“Recent crowd disasters, such as those seen in 2006 during the annual pilgrimage to Mecca and in 2010 at the Love Parade in Duisburg, have underlined the need to better understand what determines the collective behavior of crowds. In a study published in PNAS on 18 April, scientists from CNRS and the Ecole Polytechnique Fédérale in Zurich managed to simulate collective movements resulting from interactions between pedestrians within a crowd. Their work enables them to predict potentially dangerous situations and to propose a regulation of movements in the event of a proven risk.”
“Engineering researchers the University of Southern California have made a significant breakthrough in the use of nanotechnologies for the construction of a synthetic brain. They have built a carbon nanotube synapse circuit whose behavior in tests reproduces the function of a neuron, the building block of the brain.”
“People may advise you to listen to your gut instincts: now research suggests that your gut may have more impact on your thoughts than you ever realized. Scientists from the Karolinska Institute in Sweden and the Genome Institute of Singapore led by Sven Pettersson recently reported in the Proceedings of the National Academy of Sciences that normal gut flora, the bacteria that inhabit our intestines, have a significant impact on brain development and subsequent adult behavior.”
“Zhenzhen Zhang from the Department of Epidemiology at Michigan State University and his colleagues decided to Meta-analyze and systemically review previous studies. They searched electronic records from MEDLINE, EMBASE, Agricola, and Cochrane Library and gathered information from six previous studies that had followed coffee drinkers over long periods of time, some as long as 33 years.”
“Based on the study results, Europeans who described themselves as being “very happy” went from 28 percent down to 23 percent as their work hours increased. Americans, on the other hand, remained at 43 percent regardless of how many hours they worked.”
“The romantic relationships of active Twitter users apparently don’t last as long as the rest of the population.
Dating trends website OKCupid studied more than 800,000 of its users. The study showed people who use Twitter every day tend to have shorter relationships. And the problem gets worse as the person gets older.”
