A. Science and Technology News
Nanomagnets Can Clean Arsenic-Contaminated Water
New technique generates great promise for the treatment of millions of wells currently believed to be contaminated with dangerous levels of arsenic. Scientists at Rice University, in Houston, USA believe the properties of magnetic nanoparticles of rust tend to bind to arsenic and make them ideal for removing arsenic from contaminated well water using little more than a magnet. Arsenic sticks to rust, says Vicki Colvin, a chemist at Rice's Center for Biological and Environmental Nanotechnology. And since rust is essentially iron oxide, it tends to be magnetic, so it can be drawn back out of the water using a low-powered magnet.
According to the World Bank, nearly 65 million people are at risk from arsenic-related health problems, largely due to contaminated wells. The situation is so dire that it has led to the creation of a $1 million cash prize, called the Grainger Challenge, to be awarded to whoever comes up with a practical solution to removing arsenic from wells in many developing countries. Until now it was thought that such particles, which are around 10 nanometers in diameter, would need powerful electromagnets to generate fields strong enough to overcome local forces acting on the tiny particles. But Colvin's team, which published its results in the journal Science, shows that even low-power magnets can do the trick. "The particles magnetically interact," she explains. This allows them to behave, at least magnetically, like a larger magnet, and therefore be influenced like one. The Rice technique could provide a far more practical approach. While Colvin's experiments used relatively expensive nanoparticles, she is confident that ultra-small rust particles can be easily and cheaply generated. As for the magnets, these can be recovered from the hard drives of old computers, many of which end up in Southeast Asia, she says. For more information, please see: http://snipurl.com/13f4y.

Low-cost Broadband from High Altitude
Broadband communications may be about to get a whole lot faster and cheaper, thanks to high-altitude platforms (HAPs) that can relay wireless and optical communications to remote areas. The revolutionary CAPANINA project is the brainchild of a consortium drawn from Europe and Japan and led by the University of York, UK. HAPs are essentially airships or aircraft operating in the stratosphere, and due to their altitude (17-22 km) they have the potential to deliver services over a wide coverage area. The CAPANINA project is focusing on development of low-cost broadband technology from HAPs aimed at providing efficient ubiquitous coverage to users who may be marginalized by geography, distance from infrastructure, or those traveling inside high-speed public transport vehicles. Users in rural and other 'hard to reach' areas will benefit thanks to the unique wide-area, high-capacity wireless coverage provided by HAPs. Additionally, use of "smart" roof-top antennas on trains will provide the moving user with high speed internet connectivity.
Whatever a user wants to do, be it browse the internet, download a movie or song, select video on demand or use any other bandwidth hungry application, HAP broadband delivery systems will ensure more cost effective availability to all. The new innovative communications system, say scientists, could provide inexpensive broadband connections to isolated areas, with data rates expected to be 2,000 times faster than traditional dialup and 100 times faster than current "wired" ADSL broadband. "The potential of the system is huge, with possible applications ranging from communications for disaster management and security, to environmental monitoring and providing broadband for developing countries," said Dr David Grace, CAPANINA's Principal Scientific Officer.

Cheap Ethanol from Wood Chips
Efforts are on the way to produce commercially viable ethanol from cellulosic sources such as cornstalks and wood chips. This was found through the research of Lee Lynd, professor of engineering at Dartmouth College and a cofounder of Mascoma Corporation, based in Cambridge, Massachusetts, USA. Experimental methods for converting wood chips and grass into ethanol will soon be tested at production scale. The company is building demonstration facilities that will have the capacity to produce about one-half to two million gallons of ethanol a year from waste biomass. The optimized process shows enough promise to invest in scaling up the technology, says Colin South, Mascoma's president. If the fuel is to replace a sizable fraction of the huge amount of gasoline currently consumed each year all over the world, ethanol producers will need to turn to biomass such as wood chips and grass. These resources are cheaper and potentially much more abundant, and they can be converted to ethanol much more efficiently than corn can because they require less energy to grow. Gregory Stephanopoulos, professor of chemical engineering at MIT also agrees to this viewpoint. He says some experts estimate that with gains in efficiency and high yields of ethanol, all the gasoline for transportation could be replaced; the most conservative estimates say that about 20 percent could be replaced.

Peer Review Practice in Europe Needs Changes
Experts have expressed concerns that peer review, the internationally accepted form of scientific critique, may no longer be receptive to the novel approaches that lead to valuable scientific advances. In an international conference organized jointly by the European Science Foundation (ESF), the Czech Science Foundation, and the European Heads of Research Councils (EuroHORCs), the speakers have indicated that the current system of peer review could at times be considered 'tyrannical' in its approach and it needed to evolve. Over the course of the two-day event, held on 12-13 October 2006, some 150 experts from the European scientific community and institutions throughout the world (including China, Japan and Korea) convened to discuss the growing need for access to the best quality expert reviewers and the provision of suitable incentives for these scientists, including financial remuneration.
The president of the ESF, Ian Halliday, suggested that the future of European peer review lies in the creation of international expert review panels. He concluded that many research areas would benefit from a common pool of international referees. He also referred to the good examples set by the US National Science Foundation (NSF). It was agreed that overall, peer review remains the best method of judging scientific quality both in research proposals and publications, but that its inherent subjectivity and variability can cause problems. Further workshops and a final meeting will take place in 2007 to implement the findings of this ongoing activity. Please see: http://snipurl.com/13f8h.

EuroDYNA Conference Searches Answers to Human Disease
At a recent EuroDYNA conference in Brno, Czech Republic 60 scientists from nine European countries came together to present their research. A number of highly prominent researchers in the field of genetics and cell nucleus architecture discussed and debated their recent findings in details. Discussion ranged from the understanding of gene silencing in zebrafish to investigating the scaffolding of the nucleus. It is hoped that understanding the intricate processes of the body could lead to a better way of combating human disease. Gene silencing is of great importance in both plants and animals as it is essential for regulating genes and participates in the defense against viral infections. Leonie Kamminga, Hubrecht Laboratory, Utrecht, Netherlands has found that a protein called ziwi is linked to the presence of reproductive cells in zebrafish. When ziwi is silenced in zebrafish, the reproductive cells are absent. Understanding cellular processes are important in understanding the cause of disease. No cellular process is 100 per cent efficient and cell division failure is harmful and can lead to tumours. Kim Nasmyth, University of Oxford, spoke about the structure of cohesin, the substance which hold the genetic material together in the nucleus. Nasmyth described how cohesin is made up of two protein arms joined with a hinge. DNA is held in place in between the two arms. Nasmyth is working on developing a model to picture the interactions between cohesin and DNA during cell division. The conference demonstrated that there is still much to learn about the body's small components but that scientific synergy and pan-European collaboration could help to achieve this goal.

Speakers Emphasized to Make Sigma Xi Truly International
Sigma Xi should put in more efforts to make the Society truly international - this was agreed by all discussants in one of the chapter sessions of Sigma Xi's Annual Meeting in Detroit. In the session, named "Is Sigma Xi Really an International Society?", one of the panelists, Dr. Antonio Pita, Director of the Canadian/International Constituency Group mentioned that although Sigma Xi has endeavored to build its international membership, only a few active chapters and partners currently exist. He raised a question whether Sigma Xi should strive to be truly an international scientific society. If so, how should its efforts be directed, and how could Sigma Xi be a driving force in promoting international S&E partnership. Another panelist Dr. Michael Crosby, Executive Director, U.S. National Science Board informed that NSB was examining the role of the US Government in supporting international science and engineering (S&E) research partnerships and how such partnerships might be used to achieve benefits beyond just doing "good" science. According to him, Sigma Xi, as an international interdisciplinary honorary S&E research society, should be uniquely positioned to facilitate international partnerships. The session was attended by current and future presidents of the Society, its executive director and a host of other leaders of the society. All of them stressed the need for more involvement of the society internationally and expressed their full support in spearheading this mission in the coming years.
