Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
Waste treatment facilities in the United States process more than 8,000,000 tons of biosolids - semi-solid sewage - about half of which is recycled into fertilizer and spread on crop land and which helps solve storage issues and produces revenue to support the treatment plants.
But what else is being spread in that sludge? As industry invents new materials and chemicals for modern products, many find their way to our skin and bloodstream and, subsequently, into our sinks and toilet bowls. More than 500 different organic chemicals have been identified in the biosolids used as fertilizer across the United States.
There is a reason some schools on the coast of California only have a 25 percent vaccination rate. Not 25 percent exemption, 25 percent vaccination. In California overall, exemptions rates rose by 25 percent just between 2008 and 2010 and that trend has been mirrored in states like Washington and Oregon.
The recent rash in anti-vaccination hysteria can be mathematically modeled, say scholars from the University of Guelph and the University of Waterloo.
The anterior insula region deep inside the brain controls how quickly people make decisions about love, according to a new paper.
The finding, made in an examination of a 48-year-old man who suffered a stroke, is the first causal clinical evidence that the anterior insula "plays an instrumental role in love," according to Stephanie Cacioppo, Director of the Center for Cognitive and Social Neuroscience Laboratory of the University of Chicago, lead author of the study who also helped create an evolutionary theory of loneliness.
First impressions are so powerful that they can override what we are told about people, say social psychologists. A new paper presented today at the Society for Personality and Social Psychology (SPSP) annual conference in Austin says that even when told whether a person was gay or straight, participants generally identified the person's sexual orientation based on how they looked.
Everyone feels neuroscience studies are biased, no matter how representative they try to be. But Roel Willems and colleagues from the Donders Institute for Brain, Cognition and Behaviour at Radboud University Nijmegen,
and Max Planck Institute in Nijmegen say studies are flawed if they don't include enough left-handed people.Because left-handed people have different brains.
Do television shows and magazines make you feel guilty for not wearing sexy lingerie, ladies? You may just need some marketing empowerment from academics in the humanities.
Luckily, at Valentine's Day, the Internet will be filled with insipid advice based on weak observational studies and surveys. So here it is: sexy lingerie may not help, but it sure won't hurt.
Can data be a tactile experience?The CEEDs project thinks it can be, and they want to use integrated technologies to support human experience when trying to make sense of very large datasets. Jonathan Freeman Professor of Psychology at Goldsmith University of London, did an interview with youris.com to outline how they believe this project can help present data better, depending on the feedback participants provide to data from their environment via monitoring of explicit responses such as eye movement, and their inner reactions, like rate. What inspired you to get involved in data representation?
Looking for a good book? Then stay away from the award-winning section of the bookstore, because high standards means a greater chance for a letdown, according to Amanda Sharkey of the University of Chicago Booth School of Business, who finds that a book read after winning a prestigious award will likely be judged more negatively than if it's read prior to recognition.
Sharkey and colleague Balázs Kovács of the University of Lugano analyze thousands of reader reviews of 32 pairs of books. One book in each pair had won an award – like the Booker Prize, National Book Award or PEN/Faulkner Award – while the other book had been nominated but hadn't won.
Asian longhorned beetles are an invasive pest that affects about 25 tree species in the United States.
Female Asian longhorned beetles lure males to their locations by laying down sex-specific pheromone trails on tree surfaces, according to an international team of researchers.
The researchers isolated and identified four chemicals from the trails of virgin and mated female Asian longhorned beetles -- Anoplophora glabripennis -- that were not found in the trails of males. They found that the pheromone trails contained two major components -- 2-methyldocosane and (Z)-9-tricosene -- and two minor components -- (Z)-9-pentacosene and (Z)-7-pentacosene.
Health education videos tell us what really matters to people.
Two videos both began by offering information about UV light and sun-protective behaviors but then one describes the increased skin cancer risk of UV exposure and the other
describes effects on appearance including wrinkles and premature aging.
Cancer is too remote, but wrinkles are real, for teenagers.
A
University of Colorado Cancer Center study shows that while teens who watched both videos
learned and retained the same amount of knowledge about UV light and sun-protective behaviors,
only the teens who watched the appearance-based video (and not the health-based video) actually
changed these behaviors.
Osteoarthritis is a leading cause of disability, characterized by the destruction of cartilage tissue in joints, but there is a lack of effective therapies because the underlying molecular causes have been unclear. A study published by Cell Press February 13th in the journal Cell reveals that osteoarthritis-related tissue damage is caused by a molecular pathway that is involved in regulating and responding to zinc levels inside of cartilage cells. A protein called ZIP8 transports zinc inside these cells, setting off a cascade of molecular events that result in the destruction of cartilage tissue in mice. The findings could lead to a new generation of therapies for osteoarthritis.
Cells communicate through proteins embedded in their cell membranes. These proteins have diverse functions and can be compared with antennas, switches and gates. For the well-being of the cell, it has to adjust the composition of its membrane proteins and lipids constantly. New proteins are incorporated, while old proteins get recycled or eliminated. The process by which membrane material gets internalized is called endocytosis. A research team headed by Daniël van Damme and Geert De Jaeger from VIB and Ghent University (Belgium), and Staffan Persson from the Max Planck Institute of Molecular Plant Physiology in Golm near Potsdam (Germany) has now identified a new protein complex which is crucial for endocytosis in plants.
