LONDON, February 25 /PRNewswire/ --
The Brazilian Municipal Water and Wastewater Treatment Market has been experiencing strong growth since 2004. However, 80% of the country's population still needs to be connected to sewage treatment facilities. To remedy this, the Brazilian government has launched Programa de Aceleracao e Crescimento (PAC), an investment programme aimed at financing municipal water and wastewater projects. The Brazilian government has set lofty goals; it plans to reach 80% population coverage in the next seven years and hopes to achieve 100% coverage by 2020.

A biochemical analysis of a rare Clovis-era stone tool cache recently unearthed in the city limits of Boulder, Colo., indicates some of the implements were used to butcher ice-age camels and horses that roamed North America until their extinction about 13,000 years ago, according to a University of Colorado at Boulder study.
The study is the first to identify protein residue from extinct camels on North American stone tools and only the second to identify horse protein residue on a Clovis-age tool, said CU-Boulder Anthropology Professor Douglas Bamforth, who led the study. The cache is one of only a handful of Clovis-age artifact caches that have been unearthed in North America, said Bamforth, who studies Paleoindian culture and tools.
A deep new image of the magnificent Helix planetary nebula has been obtained using the Wide Field Imager at ESO's La Silla Observatory. The image shows a rich background of distant galaxies, usually not seen in other images of this object.
A team of Vanderbilt scientists have invented what is basically the world's smallest periscope and are using it to look at cells and other micro-organisms from several sides at once.
The researchers have officially dubbed these devices "mirrored pyramidal wells" and they consist of pyramidal-shaped cavities molded into silicon whose interior surfaces are coated with a reflective layer of gold or platinum. They are microscopic in dimension – about the width of a human hair – and can be made in a range of sizes to view different-sized objects. When a cell is placed in such a well and viewed with a regular optical microscope, the researcher can see several sides simultaneously.
We learn a lot from genes but it turns out we can learn even more - like where you lived or even who you spent time with. It just requires knowing where and how to look.
Researchers from Stanford and Tel-Aviv University are using a technique called "reverse ecology" to examine metabolic networks and pull out proxies for reconstructing bacterial environments millions of years in the past. The work, published in the February issue of the Journal of Computational Biology, offers clues to the complex evolutionary interplay between organisms such as parasites and hosts.
Interstellar space dust from a dead star identified by a research team led by The University of Nottingham could unlock some of the mysteries of the early universe.
Dr Loretta Dunne and her team have found new evidence of huge dust production in the Cassiopeia A supernova remnant, the remains of a star that exploded about 300 years ago. The paper is set to be published in the Monthly Notices of the Royal Astronomical Society.
White people are having a tough 2009. And it's going to get worse if new research in the Journal of Personality and Social Psychology is accurate. A series of six studies conducted by University of Washington and Michigan State University psychologists says that whites react more negatively to racial minority individuals who strongly identify with their racial group than to racial minority individuals who weakly identify with their group.
The research, they say, may provide evidence for the claim from some blacks that they personally experience more prejudice than they see others receiving.
A pregnant fossil fish at the Natural History Museum in London has shed light on the possible origin of sex, according to a study published today in the journal Nature by an international team including Museum scientists.
The fossil is an adult placoderm, an extinct group of armored fish, and it contains a 5cm-long embryo. It is dated to the Upper Devonian period 350 million years ago and was found in the Gogo formation of western Australia. The fish species is Incisoscutum ritchiei and this specimen is one of the earliest examples of a pregnant vertebrate and shows that internal fertilisation, or sex, started far sooner than previously thought.
A 380-million-year-old fossil fish that shows an unborn embryo and umbilical cord has been discovered, write scientists from the Natural History Museum in Nature. The extremely rare specimen shows incredible detail. The umbilical cord is attached to an area of small bones, corresponding to the embryo. This means the fish would have given birth to live young, known as viviparity and is the oldest record of this kind known.
'The find is important because it provides concrete evidence for vivparity,' says Zerina Johanson, fossil fish curator at the Natural History Museum.
