A singing computer scientist wants to use cutting-edge technology to create Europe's first successful Internet choir.

Dr Barry Cheetham, a senior lecturer in The School of Computer Science at The University of Manchester, is seeking to combine his academic expertise in communications, networks and digital signal processing with his love of choral singing.

He is looking for funding to drive forward a project that will bring together amateur and semi-professional singers across Europe for seamless and polished live performances.

A new National Science Foundation (NSF) report finds the number of U.S. science and engineering (S&E) articles in major peer-reviewed journals flattened in the 1990s, after more than two decades of growth, but U.S. influence in world science and technology remains strong.

The report, Changing U.S. Output of Scientific Articles: 1988 - 2003, finds changes occurred despite continued increases in funding and personnel for research and development. Flattening occurred in nearly all U.S. research disciplines and types of institutions.

In contrast, emerging Asian nations had large increases in publication numbers, reflecting their growing expertise in science and technology. European Union totals also went up.

Although the addition of nutrients to soil helps to maximize crop production, fertilizer can leech nutrients, polluting the water supply. A recent study by researchers at the University of Minnesota shows alternative cropping practices may help to protect the environment by reducing high nitrate levels in surface and ground water caused by conventional fertilizer use.

Nitrogen is one of the most important elements required in agricultural systems for plant and animal production. While treatment with the correct amount of nitrogen-based fertilizer optimizes crop yield and minimizes environmental damage, too much nitrogen can lead to nitrate loss.

Human cells function through the concerted action of thousands of proteins that control their growth and differentiation. Yet, the specific function of most human proteins remains either unknown or poorly characterized.

Diseases being often due to aberrations in the function of key cellular proteins, numerous large-scale research initiatives have been launched internationally to crack the function of all human proteins.

A research team led by Dr. Benoit Coulombe from the Institut de recherches cliniques de Montréal (IRCM) describes a powerful proteomics approach that promises to have a profound impact on our current understanding of the human proteome and the function of its individual proteins.

There are lots of things that brain cells need to survive. Add to that list microRNAs. New research from Rockefeller University shows that neurons that cannot produce microRNAs, tiny single strands of RNA that regulate the expression of genes, slowly die in a manner similar to what is seen in such human neurodegenerative disorders as Alzheimer’s and Parkinson’s diseases.

To many people, the scent of jasmine flowers suggests a romantic interlude in an exotic locale. But jasmonate, the main component of the lush scent, carries far different meanings for plants. It is a hormone they use to regulate reproductive development, immunity to pathogens, defense against insect herbivores and other critical aspects of their biology.

Despite jasmonate’s importance in plant development and function, the chemical steps that convert the hormonal signal into genetic and cellular action have remained elusive. Now researchers at Washington State University and Michigan State University have identified the family of proteins that allow a plant to perceive and respond to the hormone. They have also proposed a model for how the proteins, dubbed JAZ proteins, work.
