A new study of mutations in cancer genomes shows how researchers can begin to distinguish the 'driver' mutations that push cells towards cancer from the 'passenger' mutations that are a by-product of cancer cell development. The study also shows that at least one in nine genes can be removed without killing human cells.

A new study reveals how infection with the influenza virus impacts the way that the immune system responds to subsequent infections. The research, published by Cell Press in the February 18th issue of the journal Cell Host and Microbe, provides a new understanding of the physiological and pathological consequences of the flu.
A signaling protein that is key in orchestrating the body's overall immune response has an important localized role in fighting bacterial infection and inflammation in the intestinal tract, according to a study by UC San Diego School of Medicine investigators, published in the journal Cell Host and Microbe.
Researchers, including those at MU, have found that the most effective method of care for lymphedema is complete decongestive physiotherapy, in which therapists use specialized lymphatic massage techniques to reduce protein-rich fluid buildup. Bandages and compression garments also help to reduce swelling.
A proud consumer won't necessarily make the same purchase as a contented one, according to a new study in the Journal of Consumer Research.
"Previous research shows that positive feelings produce a 'rose-colored glasses effect,' leading products to appear more desirable," write authors Vladas Griskevicius (University of Minnesota), Michelle N. Shiota, and Stephen M. Nowlis (both Arizona State University). "But we find that rose-colored glasses come in different shades."
Those unplanned grocery purchases may not be so unplanned after all. According to a new study in the Journal of Consumer Research, shoppers often expect to buy a certain number of unplanned items, and most have a pretty good idea of how much they'll spend on them.
If you believe in karma, you're more likely to have higher expectations, according to a new study in the Journal of Consumer Research.
Some consumers strategically lower their expectations in order to try to increase their satisfaction with a product or experience, write authors Praveen K. Kopalle (Dartmouth College), Donald R. Lehmann (Columbia University), and John U. Farley (Dartmouth College). But people who believe in karma tend to have a more long-term orientation, which decreases the importance of momentary happiness.
When employees are rude to one another, it creates a negative impression that affects consumer judgments of the company, according to new study in the Journal of Consumer Research.
Authors Christine Porath, Debbie MacInnis, and Valerie Folkes (all University of Southern California) conducted several studies of employee-employee incivility and found that consumers frequently witnessed incidents of employees behaving badly toward each other.
An international consortium of scientists, including Universitat Autònoma de Barcelona (UAB) researcher Deodoro Oliveira, have sequenced the genome of three species of parasitoid wasps of the genus Nasonia. The research offers new basic information on the genetic mechanisms of evolution. It is also of great importance for the control of agricultural pests and of insect-borne diseases, since parasitoid wasps bite and lay eggs on much larger insects, many of which are the ones to later cause plagues or spread infectious diseases.
Just because cricket moms abandon their eggs before they hatch doesn't mean they don't pass wisdom along to their babies. New research in the American Naturalist shows that crickets can warn their unborn babies about potential predator threats.
The ATS and the European Respiratory Society have issued official standards for the quantitative assessment of lung structure.
"This is the first concise state-of-the-art review of stereological methods for lung morphometry that formulates practical guidelines for the use of advanced imaging techniques," said ATS past president, John Heffner, M.D. "The proposed standards ensure that the three dimensional window into the lung offered by advanced imaging techniques will provide the sharp and clear view necessary for the discovery of new respiratory cures."
Consumers perceive non-profit organizations as being "warm," but not particularly competent, according to a new study in the Journal of Consumer Research.
Quebec City, February 17, 2010–The southern limit of permanently frozen ground, or permafrost, is now 130 kilometers further north than it was 50 years ago in the James Bay region, according to two researchers from the Department of Biology at Université Laval. In a recent issue of the scientific journal Permafrost and Periglacial Processes, Serge Payette and Simon Thibault suggest that, if the trend continues, permafrost in the region will completely disappear in the near future.
CHICAGO—February 17, 2010—While many people who are adopted by members of another race still identify as black or mixed race, many lack the community and cultural connections with others who share those same identities. New research in the journal Family Process suggests that adopted children of mixed race need early and ongoing experiences within the cultural communities of their origin, and with other multiracial adopted persons, to help them to build healthy cultural identities.
An Agricultural Research Service (ARS)-developed method to safely and reliably mark termites and other insects over vast acreage so their movements can be tracked is just as effective as the previous method—and more affordable.
That's according to recently published research by ARS entomologist James Hagler, at the agency's U.S. Arid-Land Agricultural Research Center in Maricopa, Ariz., and his collaborators at the University of Arizona.
