Artificial Cells: Models Of Eel Cells Suggest Electrifying Possibilities (October 3, 2008) -- Researchers have applied modern engineering design tools to one of the basic units of life. They say that artificial cells could be built that not only replicate the electrical behavior of electric eel cells but in fact improve on them, possibly driving future implantable medical devices. ... > full story
Small Fly Has Receptor For Painful Heat (October 3, 2008) -- Scientists have found that a small fly, drosophila, has a receptor for noxious heat. ... > full story
Don't Stress! Bacterial Cell's 'Crisis Command Center' Revealed (October 3, 2008) -- A bacterial cell's 'crisis command center' has been observed for the first time swinging into action to protect the cell from external stress and danger, according to new research. ... > full story
Epstein-Barr Virus Protein Contributes To Cancer (October 3, 2008) -- Researchers have shown that the EBNA1 protein of Epstein-Barr virus (EBV) disrupts structures in the nucleus of nasopharyngeal carcinoma (NPC) cells, thereby interfering with cellular processes that normally prevent cancer development. The study, published in PLoS Pathogens, describes a novel mechanism by which viral proteins contribute to carcinogenesis. ... > full story
Remembrance Of Tussles Past: Paper Wasps Show Surprisingly Strong Memory For Previous Encounters (October 3, 2008) -- With brains less than a millionth the size of humans', paper wasps hardly seem like mental giants. But new research shows that these insects can remember individuals for at least a week, even after meeting and interacting with many other wasps in the meantime. ... > full story
Reducing Work Commutes Not Easy In Some Cities, Study Suggests (October 3, 2008) -- Shorter work commutes are one way to reduce gasoline consumption, but a new study finds that not all cities are equal in how easy it would be to achieve that goal. Research suggests that Atlanta and Minneapolis may be the US metropolitan areas that would find it most difficult to reduce the miles that workers commute each day. ... > full story
Arctic Sea Ice Hits Second-lowest Recorded Extent, Likely Lowest Volume (October 3, 2008) -- Arctic sea ice extent during the 2008 melt season dropped to the second-lowest level Sept. 14 since satellite measurements began in 1979 and may represent the lowest volume of sea ice on record, according to researchers. ... > full story
Similarity Of Urban Flora: Plants In Towns And Cities Are More Closely Related Than Those In The Countryside (October 3, 2008) -- More plant species grow in German towns and cities than in the countryside, but those in towns and cities are more closely related and are often functionally similar. This makes urban ecosystems more susceptible to environmental impacts. ... > full story
Captain Birdseye's Robotic Nose (October 3, 2008) -- The captain can't freeze smelly fish that's past its best -- and Icelandic scientists can now help him out by detecting the levels of stench-making bacteria faster than ever before. A new method to detect bacteria that break down dead fish and produce the distasteful smell of rotting fish has been developed. ... > full story
Compact Fluorescent Lighting: Are We Trading Energy Conservation For Toxic Mercury Emissions? (October 3, 2008) -- New research shows certain countries and some US states stand to benefit from the use of compact fluorescent lighting more than others, and some places may even produce more mercury emissions by switching from incandescent light bulbs to CFLs. ... > full story
Simple Twists Of Fate (October 3, 2008) -- A novel study in PLoS Biology reports on some of the molecular gymnastics performed by a protein involved in regulating DNA transcription. Using state-of-the art tools, researchers observed the shape and behavior of individual DNA molecules bent into tight loops by Lac repressor, a protein from the bacterium E.coli that switches on and off individual genes. ... > full story
Chernobyl Fallout? Plutonium Found In Swedish Soil (October 2, 2008) -- More than 20 years later, researchers from Case Western Reserve University traveled to Sweden and Poland to gain insight into the downward migration of Chernobyl-derived radionuclides in the soil. Among the team's findings was the fact that much more plutonium was found in the Swedish soil at a depth that corresponded with the nuclear explosion than that of Poland. ... > full story
