"Lingo3G: text document clustering engine Lingo3G is a software component that organizes collections of text documents into clearly-labeled hierarchical thematic folders called clusters. In real-time, fully automatically and without external knowledge bases."

Captured by NASA's Chandra X-ray Observatory and combined with data from infrared and optical telescopes, this image shows the farthest galaxy cluster ever detected. Designated JKCS041, the cluster is located 10.2 billion light-years from Earth, beating the previous distance record by a billion light-years. Astronomers think JKCS041 formed just about as early as was feasible.

The most distant known galaxy cluster has been discovered with NASA's Chandra X-ray Observatory. The cluster, known as JKCS041, is located about 10.2 billion light-years away and is observed as it was when the universe was only about a quarter of its present age. It beats the previous record holder, XMMXCS J2215.9-1738, by about a billion light-years.

The contamination and potential ecological risk posed by heavy metals from thirteen (13) sediment samples from different sampling sites along the lower portion of Agusan River were analyzed and assessed using different pollution indices. The results obtained shows that the total digest concentrations of different heavy metals under investigation have the following order: Cd < Pb < Zn < Mn, for both first sampling periods. The speciation and distribution pattern have shown that significant amounts of all metals are present in the residual fraction. Similarly, oxide-bound and organic-bound fractions were found to be highly important for Zn and Mn while Cd and Pb were significantly associated in the residual and exchangeable fractions. The results of different pollution indices moreover, showed that among all the heavy metals being studied, Cd posed the highest environmental risk across all sampling stations in both sampling periods and Mn metal was highly enriched and abundant in all of the sampling stations. Importantly, PCA results suggest that Zn, Mn and Pb may have the same origin while Cd might be coming from different sources, and this is corroborated well with the cluster analysis results. The results obtained from this work provide baseline data on the assessment of heavy metal pollution in the lower portion of Agusan River. Importantly, the acquired environmental indices will certainly help safety managers in assessing and interpreting the potential risk of the sediment associated chemical status that might adversely affect aquatic organisms in the selected sampling sites.

"The CADET tool found that children consumed on average 293 g F&V (95% CI 287 to 303) per day. Clustered (by school) multilevel regression models with total F&V as the primary outcome were conducted to explore how the home environment affects children's F&V intake. Children of families who reported 'always' eating a family meal together at a table had 125 g (95% CI 92 to 157; p=

"Our knowledge of species and functional composition of the human gut microbiome is rapidly increasing, but it is still based on very few cohorts and little is known about variation across the world. By combining 22 newly sequenced faecal metagenomes of individuals from four countries with previously published data sets, here we identify three robust clusters (referred to as enterotypes hereafter) that are not nation or continent specific. We also confirmed the enterotypes in two published, larger cohorts, indicating that intestinal microbiota variation is generally stratified, not continuous. This indicates further the existence of a limited number of well-balanced host-microbial symbiotic states that might respond differently to diet and drug intake."

"MIT-based researchers and instructors Marcelo Coelho and Skylar Tibbits teamed up to tackle this very problem. Working under a grant from Ars Electronica, the pair conceived of a whole new way to do 3-D printing. Hyperform is a new strategy for designing and printing large objects irrespective of a printer's bed size. So not only can you print out that chair at home, you can also print a table, bed frame, and everything else you need to furnish a bedroom. The solution is breathtakingly simple. By merely folding the object you want to print, you can jig it to fit into a small-scale printer. In Tibbits and Coelho's project, the object is rendered in 1-D--a line--and endlessly folded into a space-filling curve proportioned to the printer's cubic dimensions. (The designers partnered with Formlabs and iterated the process using a Form 1 tabletop printer.) When the object is exhumed from the printer bed, it doesn't at all resemble its final shape. Rather, it's a dense cluster of thin but sturdy polymer links packaged in a three-dimensional puzzle that can be intuitively assembled"

ScienceDaily (July 27, 2011) - Using a measurement of the clustering of the galaxies surveyed, plus other information derived from observations of the early universe, researchers have measured the Hubble constant with an uncertainly of less than 5 percent. The new work draws on data from a survey of more than 125,000 galaxies.

Canonical discriminant analysis (CDA) in combination with cluster analysis was used to assess 296 spring wheat lines derived from a cross between Bam (drought tolerant) and Arta (drought sensitive) cultivars using stress tolerance indices, at two
