Hong Kong told to revamp air pollution rules
The Hong Kong government has been told to hammer out a timetable for new air quality rules amid increasingly vocal criticism of pollution in the global financial hub, a green group said Sunday.
Does the central Andean backarc have the potential for a great earthquake?
The region east of the central Andes Mountains has the potential for larger scale earthquakes than previously expected, according to a new study posted online in the May 8th edition of Nature Geoscience. Previous research had set the maximum expected earthquake size to be magnitude 7.5, based on the relatively quiet history of seismicity in that area. This new study by researchers from the University of Hawaii at Manoa (UHM) and colleagues contradicts that limit and instead suggests that the region could see quakes with magnitudes 8.7 to 8.9.

Medusa-structure of gene regulatory network: Dominance of transcription factors in cancer subtypes
Over the past decades, researchers seeking to understand molecular mechanisms underlying various diseases, notably cancer, have taken advantage of DNA microarrays to interrogate tissues specimen of patients for the expression status of thousands of genes at once. Jointly, such gene expression status of each gene in the genome, measured as the level of their transcripts, constitutes the gene expression profile. Since each of the tens of thousands of genes can be switched on or off, a gene expression profile contains complex information, akin to a huge bar code with tens of thousands of digits for every sample. While microarray data was initially used by gene hunters to identify novel genes, such as those which are only active in samples of particular cancer tissues, researchers have later learned to employ sophisticated computational tools to classify these bar codes into subgroups and to find subgroup specific signatures. In cancer research such statistical analysis of ge! ne expression patterns can serve to identify new cancer subtypes and help classify patients more accurately.
Study finds Filipino children in San Diego County at higher risk for Kawasaki disease
While children of all ethnicities can contract Kawasaki disease (KD), a study led by researchers at the Kawasaki Disease Research Center at the University of California, San Diego and Rady Children's Hospital-San Diego finds that Filipino children with KD are at a higher risk for inflammation of the blood vessels of the heart than those of other Asian and non-Asian backgrounds. Nearly 24 percent of Filipino children with KD in San Diego County were found to have aneurysms compared to 10.5 percent of children of other Asian descent.
Adalimumab levels detected in cord blood and infants exposed in utero

Socioeconomic status influences celiac disease diagnosis
Income is a pivotal factor in whether a patient without common symptoms of celiac disease is accurately diagnosed with the digestive condition, according to a new study from the Beth Israel Deaconess Medical Center in Boston, MA.
Season of birth and celiac disease in Massachusetts children
Celiac disease is more common among Massachusetts children born in the spring or summer, and this higher incidence could be related to the intersection of key seasonal and environmental factors, according to researchers at the Massachusetts General Hospital for Children.
Columbia engineers patch a heart
Researchers at Columbia Engineering have established a new method to patch a damaged heart using a tissue-engineering platform that enables heart tissue to repair itself. This breakthrough, recently published in the Proceedings of the National Academy of Sciences, is an important step forward in combating cardiovascular disease, one of the most serious health problems of our day.
The brain performs visual search near optimally
In the wild, mammals survive because they can see and evade predators lurking in the shadowy bushes.
In a genetic research first, researchers turn zebrafish genes off and on
Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods.
