Flat screen displays currently used in computer monitors, television sets and numerous other electronic devices are all built on a glass base. Most use liquid crystal devices (LCDs), which filter light from behind to form an image.

But the glass substrate makes LCD displays rigid and fragile, limiting their use. Now display manufacturers are working to develop a new generation of robust, flexible displays that can be curved to fit the shape of a product or even rolled up like a magazine. The question is, which of the technologies under development is the best?

Big industrial names such as Nokia, Thales and Philips, as well as universities, research centres and many small and medium-sized businesses have pooled their skills and expertise to thoroughly test a large number of materials and techniques.

Astronomers have discovered an extrasolar planet only three times more massive than our own, the smallest yet observed orbiting a normal star. The star itself is not large, perhaps as little as one twentieth the mass of our Sun, suggesting to the research team that relatively common low-mass stars may present good candidates for hosting Earth-like planets.

The astronomers used a technique called gravitational microlensing (1) to find the planet, a method that can potentially find planets one-tenth the mass of our own.

The gravitational microlensing technique, which came from Einstein's General Theory of Relativity, relies upon observations of stars that brighten when an object such as another star passes directly in front of them (relative to an observer, in this case on Earth). The gravity of the passing star acts as a lens, much like a giant magnifying glass. If a planet is orbiting the passing star, its presence is revealed in the way the background star brightens. A full explanation of the technique follows this release.

The contentious debate about why insects evolved to put the interests of the colony over the individual has been reignited by new research from the University of Leeds, showing that they do so to increase the chances that their genes will be passed on.

A team led by Dr Bill Hughes of the University’s Faculty of Biological Sciences studied 'kin selection' – the theory that an animal may pass on its genes by helping relatives to reproduce, because they share common genes, rather than by reproducing itself.

The concept of ‘kin selection’ was developed in 1964 by the evolutionary biologist Bill Hamilton, first proposed by Charles Darwin to explain, for example, why sterile workers evolved in social insect groups and why a honeybee would sacrifice its life to defend the colony. Charles Darwin recognized that such altruistic behaviour in highly social insect groups was at odds with his theory of natural selection, and Bill Hamilton’s theory of kin selection showed that this behaviour can evolve because it still fulfills the drive to pass on genes - but through relatives instead.

The actor Sir Peter Ustinov once famously said "Contrary to general belief, I do not believe that friends are necessarily the people you like best, they are merely the people who get there first." Psychologists now believe there is some truth to this argument.

Rather than picking our friends based on intentional choice like common values and interests, our friendships may be based on more superficial factors like proximity or group assignments, like a department where you work or even an entirely new job.

Mitja Back, Stefan Schmukle, and Boris Egloff of the University of Leipzig sought to test the notion that random proximity and random group assignment at zero acquaintance would foster friendship in the long run. The researchers investigated 54 college freshmen upon encountering one another for the first time at the beginning of a one-off introductory session and randomly assigned them a seat number in a group of chairs organized in rows.

When people hear about elder abuse in nursing homes, they usually think of staff members victimizing residents. However, research by Cornell University faculty members suggests that a more prevalent and serious problem may be aggression and violence that occurs between residents themselves.

Although such aggression can have serious consequences for both aggressors and victims, the issue has received little attention from researchers, and few proven solutions exist to prevent resident altercations, says Karl Pillemer, director of the Cornell Institute for Translational Research on Aging at the College of Human Ecology. He has co-authored two articles -- in Aggression and Violent Behavior and in the Journal of the American Geriatrics Society -- on "resident-to-resident mistreatment" this spring with Weill Cornell Medical College professor of medicine Mark S. Lachs, M.D., and medical student Tony Rosen. Both studies report that verbal and physical aggression between residents is common and problematic, and that more research is necessary to identify risk factors and preventative measures.

"Anyone who spends much time in a nursing home will observe arguments, threats and shouting matches among residents, as well as behaviors like pushing, shoving and hitting," Pillemer said.

Researchers have demonstrated the possibility of preventing the human malaria parasite, Plasmodium falciparum, which is responsible for more than a million malaria deaths a year, from becoming sexually mature.

The discovery could have implications for controlling the spread of drug resistance, which is a major public health problem and which hinders the control of malaria.

The life cycle of Plasmodium falciparum is complex, and it is not yet known what triggers the production of parasite gametes or sex cells. These sexual forms of the parasite do not contribute to malaria symptoms, but are essential for transmission of malaria between humans via the bite of a mosquito.

In 1928 Alexander Fleming discovered penicillin, which was subsequently developed into a medicine by Florey and Chain in the 1940s. The antibiotic was hailed as a 'miracle cure' and a golden age of drug discovery followed. However, frequent rediscovery of known natural products and technical challenges forced pharmaceutical companies to retreat and stop looking for new molecules.

Big pharmacy companies gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries.

"Over the last eight years we have been looking for new natural products in the DNA sequence of the antibiotic-producing bacterium Streptomyces coelicolor," said Professor Gregory Challis from the University of Warwick. "In the last 15 years it became accepted that no new natural products remained to be discovered from these bacteria. Our work shows this widely-held view to be incorrect."

A major contribution to the long-term storage and access of data on mutation for genes and disease has been established with the launch of Human Genomics and Proteomics, the first database journal affiliated with a database, FINDbase: the National/Ethnic Mutation Database documenting frequencies of causative mutations leading to inherited disorders in various populations worldwide.

The first title to be launched through SAGE-Hindawi – the joint collaboration between SAGE and Hindawi Publishing Corporation, Human Genomics and Proteomics (HGP) is a peer-reviewed international open access journal that will provide a unique forum for the discussion of research on human genomics and proteomics, systems biology and various aspects of personalized medicine.

One copy of the human genome is more than 3 billion nucleotides in length, and weighs in at about 3.5 picograms (pg, or trillionths of a gram). Only about 1.5% of this is composed of our 20,000 or so protein-coding genes, though other data suggest that at least 5% has been conserved by natural selection, suggesting that a notable portion of the non-coding majority is also functional. On the other hand, it is now apparent that much of the genome residing in our cells is made up of sequences like transposable elements -- "parasites" of the genome that can move about wwithin and be copied independently of the "host" genome -- and especially their extinct remnants. One such element, Alu, is present in more than one million copies.
