Coal-Tar Sealcoat a Major Source of PAHs to Air and to Children Living Nearby

*Four new reports examine the contaminants polycyclic aromatic hydrocarbons (PAHs) found in house dust, streams, lakes, soil, and air*

Coal-tar-based sealants are emitting polycyclic aromatic hydrocarbons (PAHs) into the air at rates that may be greater than annual emissions from vehicles in the United States, according to new reports by the U.S. Geological Survey, published in the scientific journals Chemosphere and Atmospheric Environment.

New Mouse Reference Library Should Speed Gene Discoveries

Genetic information provided by a large group of specially designed mice could pave the way to faster human health discoveries and transform the ways people battle and prevent disease.

In 15 papers published Feb. 16 in the Genetics Society of America journals Genetics and G3:Genes/Genomes/Genetics, researchers from North Carolina State University, the University of North Carolina at Chapel Hill, The Jackson Laboratory and other universities and labs across the globe highlight a new genetic resource that could aid development of more effective treatments for any number of human diseases.

REDMOND, Wash. – It was a story that everyone hoped wasn’t true. On Saturday, Feb. 11, the day before the Grammys, Twitter and Facebook posts reported that one of the music industry’s once brightest stars, Whitney Houston, had died. Variations on the hashtag #RIPwhitney filled the top trending spots on Twitter. Facebook feeds were filled with memories of the late singer’s music – a first kiss, a first dance or first song ever bought. And YouTube exploded with videos of Houston’s past performances.

An hour or so after reports of the singer’s death began appearing via social media sites, the mainstream media began reporting confirmations of her death. As the day progressed, the major cable news stations began reading celebrity tweets aloud memorializing the singer and encouraging readers to visit their Facebook fan pages to join in the discussion.

Color is Key in Controlling Flies, UF Researchers Find

GAINESVILLE, Fla. — As a carrier of as many as 100 types of germs, the common house fly is hardly as innocuous as its name might suggest.

Military personnel know this firsthand, and their need for effective fly control has helped University of Florida researchers create an innovative new fly control device. (more…)

High Population Density is Greatest Risk Factor For Water-Linked Diseases

COLUMBUS, Ohio – Water-associated infectious disease outbreaks are more likely to occur in areas where a region’s population density is growing, according to a new global analysis of economic and environmental conditions that influence the risk for these outbreaks.

Ohio State University scientists constructed a massive database containing information about 1,428 water-associated disease outbreaks that were reported between 1991 and 2008 around the world. By combining outbreak records with data on a variety of socio-environmental factors known about the affected regions, the researchers developed a model that can be used to predict risks for water-associated disease outbreaks anywhere in the world.

Echoes From an Exploding Star

Astronomers watch a delayed broadcast of a powerful stellar eruption

Astronomers are watching the astronomical equivalent of streaming live video of a spectacular outburst from the unstable, behemoth double-star system Eta Carinae, which initially was seen on Earth nearly 170 years ago. (more…)

When Nerve Meets Muscle, Biglycan Seals The Deal

In the absence of the protein biglycan, synapses at neuromuscular junctions in mice began to break up about five weeks after birth, according to a new study led by Brown University researchers. Reintroducing byglycan helped fix the loss of synaptic stability in cell culture. The research may be relevant to efforts to treat motor neuron diseases, such as amyotrophic lateral sclerosis (ALS, Lou Gehrig’s Disease) and spinal muscular atrophy. (more…)
