Cultural differences between countries run right to the heart of government, thereby influencing technological innovation. This is reported in a comparative study by David Calef and Robert Goble published recently in the journal Policy Sciences(1). The authors outline efforts taken throughout the 1990s by both the US and French governments to adopt legislation fostering technological innovation to improve urban air quality by promoting clean vehicles, specifically electric vehicles (EVs). The study highlights the differences in approach and policy-making style by both governments and how this might have affected the final outcome.

Threatened coral reefs could be given a helping hand by establishing marine reserves, according to a research team led by the University of Exeter. Marine reserves have already proved to be a successful way of protecting marine life against commercial fishing. Marine reserves could also help in the recovery of corals, which are already suffering the effects of climate change and over-fishing.

With the advent of more powerful and economical DNA sequencing technologies, gene discovery and characterization is transitioning from single-organism studies to revealing the potential biotechnology applications embedded in communities of microbial genomes, or metagenomes. The field of metagenomics is still in its infancy -- the equivalent of the early days of the California Gold Rush, with labs vying to stake their claim.

Amidst the prospecting, the call has been issued for methods to separate fool's gold from the real nuggets. Such a gold standard has now been provided through work led by the U.S. Department of Energy Joint Genome Institute (DOE JGI) with colleagues from Oak Ridge National Laboratory and IBM's T.J. Watson Research Center.

Researchers observing wild chimpanzees in Uganda have discovered repeated instances of a mysterious and poorly understood behavior: female-led infanticide. The findings, reported by Simon Townsend, Katie Slocombe and colleagues of the University of St. Andrews, Scotland, and the Budongo Forest Project, Uganda, appear in the May 15th issue of the journal Current Biology, published by Cell Press.

Infanticide is known to occur in many primate species, but is generally thought of as a male trait. An exception in the realm of chimpanzee behavior was famously noted in the 1970s by Jane Goodall in her observations of Passion and Pom, a mother-daughter duo who cooperated in the killing and cannibalization of at least two infant offspring of other females.

Human beings are directly responsible for more than 110,000 chemical substances which have been generated since the Industrial Revolution.

Every year, we "invent" more than 2,000 new substances, most of them contaminants, which are emitted into the environment and which are consequently present in food, air, soil and water. Nonetheless, human beings are also victims of these emissions, and involuntarily (what is known in this scientific field as "inadvertent exposure"), every day humans ingest many of these substances which cannot be assimilated by our body, and are accumulated in the fatty parts of our tissues.

Food producers in developing countries still need to make many improvements before they can compete effectively on the world market. This is the conclusion from researchers at Wageningen University after their 4-year study. They studied similar production chains in various tropical areas and recorded their findings in a book: ´Tropical food chains, Governance regimes for quality management’.

In the eye of a furious hurricane, the weather is often quite calm and sunny. But new NASA research is providing clues about how the seemingly subtle movement of air within and around this region provides energy to keep this central "powerhouse" functioning.

Using computer simulations and observations of 1998's Hurricane Bonnie in southern North Carolina, scientists were able to get a detailed view of pockets of swirling, warm humid air moving from the eye of the storm to the ring of strong thunderstorms in the eyewall that contributed to the intensification of the hurricane.

A study led by researchers at UCL (University College London) demonstrates that female reproductive function is influenced by childhood environment. This suggests there is a critical window of time from about 0-8 years of age that determines the rate at which girls physically mature and how high their reproductive hormone levels reach as adults.

A surprisingly complete fossil skull of an ancient relative of humans, apes and monkeys bears striking evidence that our remote ancestor was less mentally advanced than expected by about 29 million years ago.

The second and most intact cranium found of Aegyptopithecus zeuxis was identified by Duke University primatologist Elwyn Simons, who is announcing the find this week with several colleagues.

Professor of Women's Health Psychology at the University of Western Sydney, Jane Ussher, has been researching the issue for 20 years and says that women are being controlled by medical practices which position their unhappiness as a biomedical condition.

Women are being sold the idea that their bodies are biologically faulty and they need medication for PMS, post-natal depression and menopausal outbursts when in fact the pressures of being 'superwoman' are more likely to blame.
