(Santa Barbara, Calif.) –– Using eyes made of a calcium carbonate crystal, a simple mollusk may have evolved enough vision to spot potential predators, scientists say.
Daniel Speiser, a postdoctoral fellow in the Department of Ecology Evolution and Marine Biology at UC Santa Barbara, studied mollusks that he collected in the Florida Keys. His research of their vision, performed during his graduate studies at Duke University, resulted in a study published today by Current Biology.
Challenging traditional views of workplace anger, a new article by a Temple University Fox School of Business professor suggests that even intense emotional outbursts can prove beneficial if responded to with compassion.
Dr. Deanna Geddes, chair of the Fox School's Human Resource Management Department, argues that more supportive responses by managers and co-workers after displays of deviant anger can promote positive change at work, while sanctioning or doing nothing does not.
A dietary yeast extract could be an effective alternative to antibiotics for poultry producers, according to a U.S. Department of Agriculture (USDA) study.
MADISON – A little information can go a surprisingly long way when it comes to understanding rodent-borne infectious disease, as shown by a new study led by John Orrock from the University of Wisconsin-Madison.
COLUMBUS, Ohio – Chronic inhalation of polluted air appears to activate a protein that triggers the release of white blood cells, setting off events that lead to widespread inflammation, according to new research in an animal model.
This finding narrows the gap in researchers' understanding of how prolonged exposure to pollution can increase the risk for cardiovascular problems and other diseases.
The idea of probing the body's interior with radiation stretches back to experiments with X rays in the 1800s, but more than a century later, images taken with radiological scans still are not considered reliable enough to, for example, serve as the sole indicator of the efficacy of a cancer treatment. Lisa Karam, a biochemist at the National Institute of Standards and Technology (NIST) and a few dozen of her colleagues across North America have set out to change that.

A University of Granada research group composed of professors Antonio Campos and Miguel Alaminos (histologists), María del Mar Pérez, Ana Ionescu and Juan de la Cruz Cardona (opticians) and the ophthalmologist Miguel González Andrades, University Hospital San Cecilio, Granada, have made the first bioartificial organ in Spain
Genetically modified bacteria could be used in air filters to extract pesticide vapors from polluted air thanks to work by researchers in China published this month in the International Journal of Environment and Pollution.
Cold Spring Harbor, N.Y. -- One way of discovering a gene's function is to switch it off and observe how the loss of its activity affects an organism. If a gene is essential for survival, however, then switching it off permanently will kill the organism before the gene's function can be determined. Researchers at Cold Spring Harbor Laboratory (CSHL) have overcome this problem by using RNA interference (RNAi) technology to temporarily turn off any essential gene in adult mice and then turn it back on before the change kills the animals.
Montreal, April 14, 2011 – An international consortium of scientists, including major contributions from the Montreal Heart Institute, demonstrates that the "one-size fits all" strategy of uniformly doubling the dose of an antiplatelet drug, clopidogrel, for patients with high on-treatment platelet reactivity does not reduce the incidence on death, heart attacks and stent thrombosis after percutaneous coronary intervention (PCI).
Approximately 20% of Spaniards take non-prescribed medication and women are the group most inclined towards this practice. This is the conclusion of a research study carried out by experts from the Rey Juan Carlos University in Madrid, which also links this habit to nationality, income level and alcohol and tobacco consumption amongst the population.
A new study led by a scientist at Scripps Institution of Oceanography at UC San Diego is painting a more complete picture of an extraordinary sea worm that makes its living in the depths of the ocean on the bones of dead animals.
Producing hydrogen in a sustainable way is a challenge and production cost is too high. A team led by EPFL Professor Xile Hu has discovered that a molybdenum based catalyst is produced at room temperature, inexpensive and efficient. The results of the research are published online in Chemical Science Thursday the 14th of April. An international patent based on this discovery has just been filled.
An international study published today warns that nitrogen pollution, resulting from industry and agriculture, is putting wildlife in Europe's at risk. More than 60 per cent of the EU's most important wildlife sites receive aerial nitrogen pollution inputs above sustainable levels.
There is evidence of impacts on semi-natural grasslands, heathlands and forests across Europe. This threat is set to continue unless there is further action on emissions of polluting nitrogen gases.
The researchers also found that some cuckoo finch hosts use an alternative strategy: red-faced cisticolas lay only moderately variable eggs but are instead extremely discriminating in deciding whether an egg is their one of their own. Thanks to their excellent discrimination, these hosts can spot even a sophisticated mimic.
