Chemistry » Binding, Silk »
University of Massachusetts at Amherst − AMHERST, Mass. - Scientific debate has been hot lately about whether microbial nanowires, the specialized electrical pili of the mud-dwelling anaerobic bacterium Geobacter sulfurreducens, truly possess metallic-like conductivity as its discoverers claim. But now University of Massachusetts Amherst microbiologist Derek Lovley, with postdoctoral researcher Nikhil Malvankar and colleagues, say they have settled the dispute between theoretical and experimental scientists by devising a combination of new experiments and better theoretical modeling.

University of Granada − An international team of scientists which included three University of Granada and the Andalusian Institute of Earth Sciences researchers (a joint UGR-CISC centre) have found new data on the weather in the Mediterranean basin over the course of the past 20.000 years thanks to the chemical composition of sediments deposited in its seabed.
|Twitter Helps Smokers Kick the Habit, UCI-Stanford Study Finds|
Medicine » Smoking, Cessation »
University of California - Irvine − Irvine, Calif., March 3, 2015 - When subjects in a smoking cessation program tweet each other regularly, they're more successful at kicking the habit, according to a study by UC Irvine and Stanford University researchers. Specifically, daily "automessages" that encourage and direct the social media exchanges may be more effective than traditional social media interventions for quitting smoking.
|Amazon Deforestation 'Threshold' Causes Species Loss to Accelerate|
Nature » Amazon, Forest »
University of Cambridge − One of the first studies to map the impact of deforestation on biodiversity across entire regions of the Amazon has found a clear 'threshold' for forest cover below which species loss becomes more rapid and widespread. By measuring the loss of a core tranche of dominant species of large and medium-sized mammals and birds, and using the results as a bellwether, the researchers found that for every 10% of forest loss, one to two major species are wiped out.

University of Bristol − With the most unpredictable UK general election looming in modern times, how can big data be used to understand how elections are covered by the media? New research has for the first time analysed over 130,000 online news articles to find out how the 2012 US presidential election played out in the media.
|UBC Scientists Uncover Cause of Tree-killing Fungus|
Biology » Fungus, Walnut »
University of British Columbia − Forest scientists at the University of British Columbia believe they've discovered the root cause of a deadly tree fungus: extra genes. The fungus, Mycosphaerella populorum, uses extra genes to produce a toxin that can cause fatal lesions on the leaves, stems and branches of poplar trees. The extra genes were found through genome sequencing, the mapping of an organism's DNA.
|Study: Men Tend to Be More Narcissistic Than Women|
Psychology » Women, Gender »
University at Buffalo − BUFFALO, N.Y. - With three decades of data from more than 475,000 participants, a new study on narcissism from the University at Buffalo School of Management reveals that men, on average, are more narcissistic than women.

|Flexible Sensors Turn Skin into a Touch-sensitive Interaction Space for Mobile Devices|
Technology » Mccarthy, Liver »
Saarland University − Someone wearing a smartwatch can look at a calendar or receive e-mails without having to reach further than their wrist. However, the interaction area offered by the watch face is both fixed and small, making it difficult to actually hit individual buttons with adequate precision. A method currently being developed by a team of computer scientists from Saarbrücken in collaboration with researchers from Carnegie Mellon University in the USA may provide a solution to this problem. They have developed touch-sensitive stickers made from

Biology » Animals, Larger »
Stanford's School of Earth, Energy & Environmental Sciences − Like a master painter who uses the same brush techniques to continually create original works of art, evolution has produced unique species to fill new or vacated ecological functions by tinkering with just a few basic body plans that have changed little in hundreds of millions of years. The end result: tremendous diversity in myriad combinations of animal life.
|The Brain Works as a 'Cyclops,' Compensating the Optical Differences Between the Eyes|
Psychology » Eye, Tram »
Spanish National Research Council (CSIC) − The eyes differ in their optical properties what results in a blur projected in each retina, despite we see sharp images because the visual system calibrates itself. An international research performed by the Consejo Superior de Investigaciones Científicas has discovered that when each eye separately has a different level of blur, our brain uses as sharp reference the image projected through the less aberrated eye. The research has been published in Current Biology.
|The Politics of Inequality And the Inequality of Politics|
Psychology » Political, Economic »
Society for Personality and Social Psychology − Economic inequality is at historic highs. The wealthiest 1% own 40% of the nation's wealth. This staggering inequality raises the question, what are the psychological causes and effects of inequality? A symposium at SPSP's Annual Convention presented four talks on how subjective construals of inequality and status shape political motivations, beliefs, and behaviors. The symposium featured four presentations: Subjective Socioeconomic Status Shapes Political Preferences

Nova Southeastern University − FORT LAUDERDALE-DAVIE, Fla. - Just when you thought hurricanes couldn't get any scarier, think again. Their names roll of the tongue like a rogues' gallery: Floyd, Frances, Irene, Wilma and Andrew. But these aren't the names of notorious criminals; rather, they are just a few of the hurricanes since 1992 that have helped spread invasive marine species throughout the Florida Straits.

Institute of Cancer Research − Changing the shape of breast cancer cells could make the disease more sensitive to treatments - even driving the body's own inflammatory response against a tumour - a new study shows. Scientists at The Institute of Cancer Research, London, showed that the shape of a tumour cell is an important factor in determining its response to inflammatory molecules, which can either promote or inhibit cancer progression.
|Genetic Data Can Help Predict How Pine Forests Will Cope with Climate Change|
Biology » Variants, Genetic »
Genetics Society of America − Data from only a small number of gene variants can predict which maritime pine trees are most vulnerable to climate change, scientists report in the March issue of GENETICS. The results will improve computer models designed to forecast where forests will grow as the climate changes, and promises to help forestry managers decide where to focus reforestation efforts. The results will also guide the choice of tree stocks.
|Cities Have a Memory And Interact with Their Neighbors|
Biology » Cities, City »
FECYT - Spanish Foundation for Science and Technology − Demographic changes in large cities depend on millions of individual decisions, but the population evolves depending on two factors: what 'reminds' them of their recent past and the existence of other urban areas around them. This is the proposal supported by a Spanish-Argentinean group of researchers through algorithms, which show how American cities have a 25-year-old memory and interact with others 200 km away while in the case of the Spain these values are 15 years and 80 km.

Duke University − DURHAM, N.C. - When its environmental and human health toll is factored in, a gallon of gasoline costs us about $3.80 more than the pump price, a new Duke University study finds. The social cost of a gallon of diesel is about $4.80 more than the pump price; the price of natural gas more than doubles; and coal-fired electricity more than quadruples. Solar and wind power, on the other hand, become cheaper than they initially seem.
|Usual Prey Gone, a Fish Survives by Changing Predictably|
Biology » Fish, Langerhans »
Case Western Reserve University − A species of fish that normally eats smaller fish changes in predictable ways when isolated from its prey, research led by a Case Western Reserve University biologist found. Without the Bahamas mosquitofish to eat, bigmouth sleepers slide down the food chain and survive on insects, snails and crustaceans--small invertebrates the mosquitofish normally eats. And, in so doing, sleepers' behaviors, ratio of males to females and physical appearance change, too.
