Patterns fascinate. Particularly stripes. Found in nature in zebras, they are also found in the most unlikely places, such as powdered drugs' mixing vessel walls. In an article about to be published in EPJ E, Nirmal Thyagu and his colleagues from Rutgers University, New Jersey, USA, propose a traffic model to predict the formation of different patterns, ranging from stripes to spots.

SANTA BARBARA – Collaborators at Cottage Health System and University of California, Santa Barbara (UCSB) have identified biomarkers that may yield a revolutionary diagnostic test for pre-eclampsia, a complex and potentially life-threatening hypertensive condition affecting 5% of pregnancies worldwide.
That snake heading towards you may be further away than it appears. Fear can skew our perception of approaching objects, causing us to underestimate the distance of a threatening one, finds a study published in Current Biology.
"Our results show that emotion and perception are not fully dissociable in the mind," says Emory University psychologist Stella Lourenco, co-author of the study. "Fear can alter even basic aspects of how we perceive the world around us. This has clear implications for understanding clinical phobias."
In a key step toward creating a working quantum computer, Princeton researchers have developed a method that may allow the quick and reliable transfer of quantum information throughout a computing device
The finding, by a team led by Princeton physicist Jason Petta, could eventually allow engineers to build quantum computers consisting of millions of quantum bits, or qubits. So far, quantum researchers have only been able to manipulate small numbers of qubits, not enough for a practical machine.
A team of elephant researchers from Stanford University has transformed a remote corner of southern Africa into a high-tech field camp run entirely on sunlight. The seasonal solar-powered research camp gives scientists a rare opportunity to quietly observe, videotape and photograph wild elephants at Mushara waterhole, an isolated oasis in Etosha National Park in Namibia.
Australian scientists have unveiled a new theory which explains the mysterious phenomenon known as ball lightning.ightings of ball lightning have been made for centuries around the world – usually the size of a grapefruit and lasting up to twenty seconds – but no explanation of how it occurs has been universally accepted by science.
Miss hitting the "sweet spot" on a baseball bat and the resulting vibrations can zing your hands. Bat companies have tried for decades to reduce these painful shocks with limited success. But Daniel Russell, a professor in the graduate program in acoustics at Pennsylvania State University in University Park, has figured out that bat vibrations between 600 and 700 hertz (Hz) cause the most pain and that specifically tuned vibration absorbers are the best at combatting the sting.
Bethesda, MD, October 18, 2012 The Association for Molecular Pathology (AMP) published thereport of the Whole Genome Analysis (WGA) Working Group of the AMP Clinical Practice Committeein the November 2012 issue of The Journal of Molecular Diagnostics (JMD). Titled "Opportunities andChallenges Associated with Clinical Diagnostic Genome Sequencing," the timely report provides adetailed and compelling overview of the landscape of next generation sequencing (NGS) technologyand its clinical relevance and impact on improving patient care.
People are more likely to install a solar panel on their home if their neighbors have one, according to a Yale and New York University study in the journal Marketing Science.
The researchers studied clusters of solar installations throughout California from January 2001 to December 2011 and found that residents of a particular zip code are more likely to install solar panels if they already exist in that zip code and on their street.
An international research group led by scientists from the University of Bristol and the Universities of Glasgow (UK) and Sun Yat-sen and Fudan in China, have demonstrated integrated arrays of emitters of so call 'optical vortex beams' onto a silicon chip. The work is featured on the cover of the latest issue of Science magazine, published tomorrow [19 October 2012].
PASADENA, Calif.—Thanks to better voting technology over the last decade, the country's election process has seen much improvement, according to a new report released today by researchers at Caltech and MIT. However, the report notes, despite this progress, some problems remain.
Spurred by the debacle of hanging chads and other voting problems during the 2000 presidential election, the Voting Technology Project (VTP) was started by Caltech and MIT to bring together researchers from across disciplines to figure out how to improve elections. The VTP issued its first report in 2001.
Braunschweig/ Leipzig. An interdisciplinary team of 11 scientists from seven European countries and the USA have discussed the concept to utilize so called surplus land for the production of feedstock for bioenergy. They identified environmental, economic and social constraints but also options for efficient use of surplus land for bioenergy. The study provides a scientific background in support of a reassessment of land available for bioenergy feedstock production. Their findings were published in the open access journal BioRisk.
Qubit-based computing exploiting spooky quantum effects like entanglement and superposition will speed up factoring and searching calculations far above what can be done with mere zero-or-one bits. To domesticate quantum weirdness, however, to make it a fit companion for mass-market electronic technology, many tricky bi-lateral and multi-lateral arrangements---among photons, electrons, circuits, cavities, etc.---need to be negotiated.
PASADENA, Calif.—Imagine navigating through a grocery store with your cell phone. As you turn down the bread aisle, ads and coupons for hot dog buns and English muffins pop up on your screen. The electronics industry would like to make such personal navigators a reality, but, to do so, they need the next generation of microsensors.
The technology that opened a wealth of new natural gas resources in the U.S. is producing millions of gallons of dirty water — enough from one typical gas well to cover a football field to a depth of 9-15 feet. Cleaning up that byproduct of "fracking" is the topic of the cover story of the current issue of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.
