What can green algae do for science if they weren't, well, green?
That's the question biologists at UC San Diego sought to answer when they engineered a green alga used commonly in laboratories, Chlamydomonas reinhardtii, into a rainbow of different colors by producing six different colored fluorescent proteins in the algae cells.
WACO, Texas (March 7, 2013) - A genetic analysis by Baylor University biologists suggests that the stocking of Florida bass in Texas reservoirs impacts bass populations far beyond the actual stocking location.
The native largemouth bass has a long and nearly continuous stocking history in Texas. However, the Florida bass is widely considered a better sport fish because it grows to a greater size. Subsequently, stocking efforts in Texas reservoirs have transitioned from largemouth bass to Florida bass.
Malaria, the leading cause of death among children in Africa, could be eliminated if three-fourths of the population used insecticide-treated bed nets, according to a new study from the National Institute for Mathematical and Biological Synthesis (NIMBioS).
Montreal, March 7, 2013 – Just hours after the tragic shooting of 27 victims at Sandy Hook Elementary School, Twitter was overloaded with messages slamming reporters for interviewing children involved in the tragedy. While some of the journalists probably knew better but wanted the story at all costs, others were rookie reporters facing ethical decisions for the first time and unaware of the impact these interviews might have on the young survivors.
A new study demonstrates what researchers consider conclusive evidence that the red wine compound resveratrol directly activates a protein that promotes health and longevity in animal models. What's more, the researchers have uncovered the molecular mechanism for this interaction, and show that a class of more potent drugs currently in clinical trials act in a similar fashion. Pharmaceutical compounds similar to resveratrol may potentially treat and prevent diseases related to aging in people, the authors contend.
Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.
FROSTBURG, MD (March 7, 2013)—Prairie dogs pull up stakes and look for a new place to live when all their close kin have disappeared from their home territory--a striking pattern of dispersal that has not been observed for any other species. This is according to a new study published in Science by behavioral ecologist John Hoogland, Professor at the University of Maryland Center for Environmental Science's Appalachian Laboratory. He has been studying the ecology and social behavior of prairie dogs in national parks in Arizona, South Dakota, and Utah for the last 40 years.
Looking at the transformation of a fly larva into a pupa may help researchers to understand the molecular mechanisms that trigger puberty. A study conducted on the fruit fly, Drosophila melanogaster, by scientists at the Institute for Research in Biomedicine (IRB Barcelona) led by ICREA research professor Marco Milán, identifies an miRNA as key to the relationship between hormones that control growth and sexual maturity.
INDIANAPOLIS -- A large randomized controlled study is among the first to rigorously demonstrate that health information technology can improve compliance with patient care guidelines by clinicians in resource-limited countries. The study was led by Regenstrief Institute investigator Martin Chieng Were, M.D., M.S., assistant professor of medicine at the Indiana University School of Medicine, and Regenstrief Institute affiliated scientist Rachel Vreeman, M.D., M.S, assistant professor of pediatrics at the IU School of Medicine.
UAlberta medical researchers and their American colleagues have discovered that the "gateway" known to control the movement of molecules in and out of a cell's nucleus appears to play another critically important role – one no one had noticed until now.
Geneva, Switzerland (07 March, 2013) – A new survey reveals that more than half of British women did not play competitive sport or spend any time on intensive workouts such as running or cycling, in a given week. Seven months on from the 2012 Olympics, British women are still less likely than their European counterparts to devote any time to competitive sport, with Britain trailing behind Germany, Denmark, Sweden and France, according to a new multi-national survey on sport and exercise habits.
Geneva, Switzerland (07 March, 2013) – A new survey reveals that 1 in 3 Danish women did not play competitive sport or spend any time on intensive workouts such as running or cycling, in a given week. However, more Danish women were physically active than their European counterparts in Germany, France, Sweden and the UK, according to a new multi-national survey on sport and exercise habits.
SAN FRANCISCO -- Weight loss study participants who received financial incentives were more likely to stick with a weight loss program and lost more weight than study participants who received no incentives, according to Mayo Clinic research that will be presented Saturday, March 9 at the American College of Cardiology's 62nd Annual Scientific Session.
Scientists at A*STAR's Genome Institute of Singapore (GIS) have developed a novel technique to precisely monitor and study the evolution of micro-organisms such as viruses and bacteria. This is an extremely important capability as it allows scientists to investigate if new drugs designed to kill them are working, and catch the development of resistance early on.
